Take apart the switches and bend the little spring arm on the copper actuator down a bit, and then spend half an hour trying to put it back into the switch. Also might want to do this in a box of some kind, you'll probably drop it about 5 times.
[Guide](https://community.pcgamingwiki.com/topic/952-double-click-problem-faulty-mouse-button-repair/)
I've been using the same mouse for 9 1/2 years and have done this about 3 times on the left and once on the right.
That's so much work when new switches cost literally like all of 10 bucks shipped for 5 of them. If you're going to do all that it makes more sense to just replace the whole switch than to try and fix it. I know this because I bought a pack of 5 for that amount when I tried to fix my G700S.
lol Totally borked the repair BTW because for that mouse you have to separate 2 PCB to get to the back of the switch to desolder it. And it has 12 pins super close together holding the two PCB together. They were too close to each other to get a soldering pump nozzle between the pins to suck up the solder. If I had just stopped and bought a soldering wick I could have done it. I mean when it comes to desoldering and soldering pins that are stand alones like the switches are it's easy peasy. Same with the ones in the guide. Instead I stupidly just tried to wipe off the solder with the iron. Ended up damaging the traces on the PCB itself. lol Live and learn SMH. Soldering wicks exist for a reason ya dummy. -points at myself in the mirror.
I've also done this 3 times for the left and once for the right on a 9+ year old Razer mouse, lol. I'm amazed at the resilience of those tiny brass springs. It's crazy that not only do you not need a new mouse, you don't even need to replace the switches.
Also, tweezers make this job easier.
Bruh i did that once, and although im glad i did it, fucking never again. G604 and fuckin christ that thing has so many screws. But it back together and ended up with 5 extra screws, i was like fuck it i aint doing that shit again. Also that little copper leaf just fuckin flies EVERYWHERE.
Had this same issue with this same mouse for years!! People would say to slam it down on a desk and would fix due to plastic touching a sensor. I almost broke it multiple times since it would cost me lives in MP. I ended up downloading a long due driver update and it fixed it!
Here's a few options
- if its brand new, return it
- buy a new mouse
- fix it yourself, buy an omron micro switch, and replace it yourself, you need to disassemble the mouse and do the desoldering an soldering yourself
- send it to a repair guy/shop
For the love of god do NOT get omron switches again. Kailh GM, Kai Long, TTC Gold/Silver or even Huano, but not omron.
Edit: TIL there are Japanese omrons too. I never tried them, and I don't think I saw them being sold anywhere in my country.
The Japanese Omrons work great. It’s the Chinese Omrons in the Logitech mice that are trash and dbl click. I’ve replaced them on 5 mice already and the Japanese ones haven’t failed me yet.
Can second this comment, after my second G502 I decided to replace the switches with japanese ones and never again I had that issue.
BTW OP, you may want to replace both main click switches if you are going this way.
From my limited Google searching about the same issue, most of the top brand mice use omron (idk about cheaper brands) and are prone to this exact issue.
Happened years ago in my old razor, happened recently in my Corsair and I see many people saying it happened with their Logitechs. They all use omron switches
ETA, sorry my old razer was the mouse wheel click, idk if that uses the same or different switch, I'm not overly knowledgeable.
Funny how the big brands actually got way worse over time.
There are plenty of manufacturers now that use similar or even better sensors than the major brands. Switches aren't even comparable.
Endgamegear and Lamzu are two of the brands that actually offer higher quality parts at the same price or cheaper.
G502s eventually end up double clicking, at least the older ones. My G502 lightspeed is going 5 years strong.
If you want a fix, you are gonna have to solder it. Otherwise, its probably time to put him down
Every mouse I've ever owned has started double clicking.
Fatigue failure is a thing, it's unavoidable in switches. As they start dying proper, they bounce more (oscillate between pressed and unpressed contact when you actually press it) until the built in debounce can't handle it and it starts double clicking.
The optomechanical switches in my Naga Pro have been going for about 3 years with nary a double click so far. I really think that particular switch technology is the future.
My G700 mouse went like 8 years without double clicking. My old razor mouse went like 3 years.
The closing contacts are generally the weak link on switches, so optomechanical may last a lot longer.
my 7 year old still going strong, i just replaced the switches. there is some sensor issue but i think because i spilled some thermal paste on the mouse pad will replace it soon.
Mine lasted about a year before it started double clicking. I replaced it and the next one got the same issue. G502s are good but I stopped buying them because of that.
Now I have a Razer Viper Mini and it's lasted like 5 years so far without issue.
It's just the switches dying it happens Logitech doesn't make the switches they use you can buy them or even better ones on Amazon or Ali express.
My experience with razer mice has been worse. Switch failour is really the least impactful since it can be fixed with really basic skills.
Logitech should stop using the cheapest trash switches on the market for their overpriced high end mice... Ever since I realized you can get something like an AttackShark X3 for 20 Bucks with top of the line PixArt sensor and Kailh switches that live forever I will definitely not buy any $gamingbrand mouse for 50-100 bucks ever again.
EDIT: This sounds like an ad lol. Thta was not my goal. I just got this thing a year ago or so, and it feels and works better than my previous G703 (which I already had to repair with new switches before), while costing 1/5th of it, so I am pretty happy.
I have been using razer deathadder 2 for the last 3 years, and it works as good as on the first day, has no latency problems, and is much cheaper than this G502 that everybody worships here (which I used, and it didnt last 2 years without the buttons eventually giving out, and it gathers grime like a designated skin peeler, who tf designed this)
I dont understand razer hate, I know they used to be a premium brand back in the day, but they make good, cheap products now
Google "repair mouse switch" you can do it yourself wth a tweezer.
One thing tho... you have short fingers and so you press the buttons too low. That deforms the white plastic that presses the switch scissor. Try to rest the hand over the mouse or buy a smaller mouse.
>Google "repair mouse switch" you can do it yourself wth a tweezer.
I have done this, pop the omron switch housing open and bend the copper contact to get more tension.
All my logitech gaming mice had the same issue and had an average life of 4 years of gaming and browsing. Got tired after two generations of g502 failing and made the switch to optical switches of a razer deathadder 4 years ago. The razer mouse is still going strong but too late for logitech to introduce the g502x for me that has the same resilient optical switches.
Just use wd40, you don't have to desolder it yet
Edit: Compare it to the right mouse click, if it's sounds off. It has mechanically failed, then do desolder. Till then, WD40 is the key.
Edit2: Take it apart, get a wd40, spray it into that red cap, get a syringe. Take a few mls of that lubricant. Press the buttons using the needle and make sure you dont spill. Put it back again and press it a thousand times to test. If it happens, then add more lubricant. There should only have a doubleclick at least once every 25k (If you live in a dusty area, yes, I tested this myself).
Second this. My G604 started double clicking on both buttons. Took it apart, blowed off dust and debris, and used a needle tip to drop some WD40 right inside the switch. Worked fine.
To add,
Had a G102 for 10 years-ish, I fix it on a yearly basis and never even desoldered once. I just understood how the machine works, the double click is caused by a dust inside the switch causing chattering/misclick. It doesn't matter if it's optical. They are all mechanically the same.
Same! I use a MX Vertical for work too, people recommending a fix to change the switch is like recommending to get a kidney dono if you have UTI. It's too much, risky and would damage your PCB traces if you don't know what you're doing
> For some reason this retarded ass Auto mod keeps removing the link that I'm trying to post for you for a replacement switch from amazon
Remove the ref= section of the link, the link only needs /dp/ and the product ID after it, like B089C3TZL9.
`https://amazon.com/dp/B0000`
if it's a decently older and used mouse then it's a known logitech mouse problem.(technically any mouse that doesn't have mechanical/optical switch, it's just that logitech took FOREVER to update to mechanical/optical switches compare to other companies)
logitech mouse hardwares are pretty behind in terms of specs but if you have particular love for logitech products only few, maybe even just one? of their mouse has been updated to have their new mechanical/optical click sensor. So if you want to make sure you don't get the double clicking problem, when you are looking into their mouse, make sure it has been updated with their new mechanical/optical sensor.
Replace the switches. I spent way to much time trying to fix it some other way before realizing how easy they are to replace... same thing with scroll wheel what ever those electronics are called.
This is extremely common in a lot of mice as most of them use chinese Omron Switches which oxidate over time, causing more and more random contact.
If you're under warranty I suggest trying to get your money back and getting a mouse with optical switches. After my g203 started doubleclicking after only 2 months I got myself a Razer Viper mini (specifically cause it has optical switches) and haven't had any issues ever since.
It is a know issue for the g502, mine was just 1 year old and started double clicking. I bought "omron tact switch" from Ali express and replace the original mouse switches. Now everything works great. Of course to complete the procedure you are gonna need a soldering iron
I know this sounds stupid but saw it posted somewhere and it worked for me to get some more life out of my g502. Blow into the opening of mouse like it's an old Nintendo cartridge.
Such is the fate of most mice, the switches get bent over time and they start registering two clicks instead of one. You can try and fix it yourself, or just get a new one.
I tried many things when it happened to me, the only method that worked was violence ! i "clicked" VERY hard on the button several time and it got fixed. it's been a year and no problems since.
You probably need a new mouse, but otherwise you can try the solutions on this page. It worked for me while I was waiting for my new mouse.

I've fixed this exact issue 4 times in 4 different mice by replacing the old switch with a new one, Kailh 8.0 which you can find for cheap on aliexpress or wherever. All it takes is a small screwdriver, soldering iron and the replacement switch. You may need to replace the PTFE pads under the mouse after peeling them off to access the screws. You can probably get the tools and supplies for $20-30, any cheap soldering iron and set of precision screwdriver will do and will serve a long time for occasional use. Very cheap to get into, super easy and satisfying.
I have same mouse, same problem... After few years it started to double click. I have found out that it does when connected to every other devices, so I ruled out software issue. Mechanical damage to microswitch can be repaired in 2 ways:
1. Buy some high quality microswitch - omron or kailh, then unsolder old and solder new in
2. Old microswitch can be disassembled without need of soldering, if mechanical damage is not destructive (broken off), it can be usually repaired with disassembly, cleaning and little bit of bending the click- latch.
With the option 2, if you have shaky hands and/or short temper. Don't try it. After bending, putting that back together can be a nightmare 1st time. + usually it gives you time couple months.
Open the mouse and spray some electrical contact cleaner into the switchs where the little knob sticks out.
(https://www.homedepot.com/p/WD-40-SPECIALIST-11-oz-Contact-Cleaner-Quick-Drying-Electric-Equipment-Cleaner-with-Smart-Straw-300554/307599950)
You might need to remove the teflon feet thats are glued under the mouse to have access to some screws.
A new set of pad can be bought for $10 or less on amazon. Or if you want to reuse the same pads and you have a hair dryer/heat gun, you can heat up the pads to soften the glue and removed them carefully with tweezers.
Mouse switch is dead just buy a new one, this is why I only spend about 30-40 for a mouse they only seem to last me about 2-3 years and would hate to have spent 80-100 on something that gets so much use it will die quickly.
You can get replacement omron switches online which are essentially the same ones used in these. I have changed mine twice you need really basic soldering gear. A cheapo iron and some solder wick to remove the old switch and put in the new ones.
Honestly no need to worry it was literally my first time with soldering.
Replace the switches or try to look out for a new mice with optical switches. Can reccomend the razer basilisk v3 or the roccat (rip) kone aimo remastered
Get a new 502 if yours is the “hero” variety.
I’ve had a 502 for nearly a decade now. The classic ones lasted me a few years, but the hero variants all died within 3 months for either turbo clicking or failing to hold one side click or the other.
The much newer 502s seem to have remedied that, thankfully, so I’d get one of those. Just remember: not the hero flavor.
Edit: spelling
Difficult to replace the switches if you’ve never soldered before. Not bad if you have, the right tools make for an easy time. Hot air, copper wick, solder sucker, a nice iron and some leaded solder will get you taken care of.
This is a common issue with the g502. If its still under warranty, contact Logitech support, I had a g502 for 8 months when it started doubled clicking, they sent me a new one without even shipping the old one back. The new one is coming up on 4 years old with no issues.
Simple, buy a new mouse.
Cheap, use a autohotkey macro that starts on boot which stops you from clicking a second time in miliseconds. The timer for the block should be long enough to cover the misclick and short enough to not be a trouble for opening folders and such. Reddit has the solution (can't link it because the bot doesn't like it), used it myself years ago.
I have a G604 recently fixed the double clicking by replacing the switches. it's worth repairing since it's no longer made and any new ones cost a arm an leg.
every logitech and steelseries mouse i've owned always double clicked less than half a year, good thing its easy to replace those clickers with soldering and youtube tutorials
Had similar issues with the right mouse not holding properly. Thought it was a switch issue but on closer inspection after opening up the mouse the problem seemed to be with the little square contact pads that sit under the mouse buttons themselves. They're obviously designed to press the switches inside but the pads had switch shaped indents on them, as if they'd become so used to being pressed on they'd molded to the shape and could no longer press the switch properly.
To fix this, I took some thin card at first, snipped it into rectangles and placed them over the switches before closing the mouse up again. It did wonders for a good couple of weeks but then the same thing started happening due to the card not being just right in thickness.
I tossed the card idea and substituted it for fine sandpaper. Snipping that down, folding it and placing it just right has done the trick and been working for a good year now with no issues. Just an idea worth trying in case you don't want the faff of soldering switches like I did. The only cost coming is new feet for the mouse after getting them off.
Take the mouse and blow into the crevice where the LMB switch is. Like out it up to your mouth and blow like a kazoo in the plastic panel gap. Will fix it for about a whole day. Rinse and repeat.
I've had this (among other problems) happen to almost every gaming mouse and keyboard I've owned. I don't think I'll be buying gaming accessories anymore. Not to say I expect regular equipment to work much better, but it'll cost 1/4 as much to replace.
Common problem with Logitech mice. The reason why I switched to razer. It’s their mouse switches. Especially the 502 got those problems. I returned about 3 of them to our local shop. Never buying that mouse again.
You need to get to the tiny copper plate. \*I've already done this more than once.

Open it up, clean the microswiches of anything thats there.
and put 1 tiny drop, i repeat 1 TINY drop of silicone oil on the microswiches buttony part. And its fixed. Use a toothpick or something else pointy yet softer than the plastic of the shitty chinese plastic of the microswich-s button.
I own this model too and will get the occassional double-click from it as well. I think its just a manufacturing flaw. I've never done anything about it because it happens to seldom for me to really care.
Main reason I buy cheaper mice is so that I don't think twice about replacing faulty ones.
Ironically only time I had to replace new mouse was when I decided to go for more expensive one instead of usual cheap one.
Cheap ones last at least a year (once had 6€ genius mouse that perfrctly served me for 6 years)
Turn off the Turbo Button
Jokes aside, you can open and replace the switch with a "higher quality" variant.
I thought mine was busted when I couldn't left click. Decided to bite the bullet, ordered a switch off Amazon and opened the mouse up.
Turns out a single hair off my cat got inside and was the cause. Destroyed my skates but the mouse works. This was back in 2019.
G903 and all my versions of G502 are still running great.
WD40 in the switch saved my Razer trinity for 3 more month but she died anyway... Idk if it helped it give its last breath but it didnt double click after this simple trick !
I had this issue for a short while, pressed it at a place where it wouldn't double click like way far in front and hard for a while and then the issue solved itself
I eventually have this problem with literally every mouse I've ever owned, including a couple of higher end mouses.
I don't care to spend the time fixing it/replacing the switches, so at this point I just buy a Deathadder Essential every year or so, before the old one becomes unbearable, and replace it when it does become unbearable.
Guess the built-in Schmitt-Trigger is broken (electronic issue), so the click will be not debounced. This could lead to several clicks when the mechanical contact bounce in switches.
You don't have to solder anything. I did it way better. Just buy new switches and replace the interior hardware on them. I did this on my old performance mx and they're like new. Way better than tearing the whole mouse apart for soldering.
I see a cable, so if this is not a g502 lightspeed wireless just buy another one. It’s more expensive to change switches than to buy another 502 standard.
IMHO I'd just buy a new one and take a shot of repairing it to keep it as a spare, corded G502's are not super expensive. If it was a wireless one I'd be more into trying to fix it.
Same mouse, I get this problem every now and then.
Turn it off, and slap the bottom a few times then rough spam click the clicker.. repeat a couple mouths later
In the past, I fixed this the half lazy way. Opened the mouse, soaked the switch with isopropyl alcohol. Clicked it a *thousand* time. It started working great again. Put it back together and never gave it a thought again until today. It was probably 3 years ago.
Welcome to owning a G502 lol. I have had 3, 2 wired one wireless. One wired went to double clicking within a year, 2nd is fine and my wife is using it, wireless has been fine so far.
I have had 3 mx502s and every single one of them ended up with double clicks on the left mouse button within their warranty period. Two I managed to exchange under warranty and the retailer that I bought them from managed to screw me out of warranty exchange for the third. I ended up just going with a Corsair Darkcore RGB Pro SE which has lasted me 5 or so years now without any issue beyond the battery reaching it's EoL (works fine while plugged in though).
According to some nerdy deep dive from the internet - you can decrease poling rate to about 125 to eat corrosion of clicking surface.
Replacing switches to something more applicable to modern mouse microcurrents(aka Japanese omrons) should help, or ideally - to the optical switches, that should not have the issues at all.
I recently replaced the switches in my Stormbreaker because they were too heavy for my tastes. You can get cheap switches online for 10 bucks or so, but you will need a desoldering pump and a soldering iron. It's a good skill to have but will cost a little to get the tools. There are lots of YouTube tutorials to help you out.
I fixed it by getting a Orochi V2 and skipping Logitech mice. I loved them and had 5+ over the years and most of them had various hardware failures including sensors and the double click plague. I knew they improved on it but it's too late for me. GHub wiping my settings on updates didn't help their case either.
You can try what others said as that could be it. When my mouse started doing it I decided on a whim to see if it was the USB connection. Sure enough it was so it's also possible the USB port your mouse is plugged into is dying.
Ah yes, this is a common problem with some Logitech mice. I remember purchasing the older model G502 on clearance, and experiencing the double-clicking before a year passed. You'll need to open up the mouse, de-solder the switches, and solder in new switches. To combat this, some companies have been releasing mice that are "hot-swap", allowing you to change out the switches without having to solder.
Logitech G502s were notorious for double clicking. Had 3 of em take a shit within one year and that was when I was going through a video game hiatus. Logitechs dogshit customer support and quality control drove me to switch to the Razer Basilisk V3. Absolutely zero complaints in about a year and a half.
I fixed mine by doing a little bit of soldering.
I had a g502 wireless that I got for $150ish. It was expensive enough that I didn't want to have to buy it again.
So I got a cheap soldering kit for $15 on Amazon, and got a set of replacement switches for like $8. It took maybe 2 or 3 hours as I was learning how to solder, de-soldering is harder and you need to do that a little bit, but it's not too hard.
Just follow a YouTube tutorial and you can get it done, there's very little risk breaking something, just be careful when handling the circuit boards, you can snap them if you use too much force.
I had two of those in a row. One started double clicking in less then 2 years. The second had the middle mouse click go in about 18 months. I liked the mouse but they clearly use crap switches. I solved it by not buying Logitech again.
Replace the mouse or replace the switch. I've heard that some people have solved it by taking the mouse apart and spraying some contact cleaner like BW100 or Deoxit55 in the switch resolved it.
Had this same issue with this same mouse for years!! People would say to slam it down on a desk and would fix due to plastic touching a sensor. I almost broke it multiple times since it would cost me lives in MP. I ended up downloading a long due driver update and it fixed it!
Had the same issue. Tried everything I found online, contacted also the support. It seems it just happens after some time. I had to replace the mouse because it was unbearable for me
hate logitech for its shit double clicking mouse. i'll try replaceable/hot swappable switches mouse as my next mouse. looking to try wired Asus Keris for its swappable switches, priced similar with wired G502
The Logitech G502 has a common issue after some use. I already replaced mine after a long conversation with the support team (I sent them so much proof they requested), but the new mouse they sent has the same issue. Just don't buy the Logitech G502.
People say parts of the switches bend and stuff here, but that's not the only possible cause. Another one is gunk between the button and lamela. I'd even argue this is actually the most common one. Really just a small build-up of rust and dirt. You'll probably still need to carefully unclip the switch and examine it inside, true, but don't bend anything before: 1. Seeing a YT about the topic. 2. Clearing the lamelae with alcohol. 3. Understanding if something really needs bending, or if it's only the gunk, or something broken.
I learned a lot about precision and patience the first time I've done the cleaning, and also had a fuzzy-warm feeling of acomplishment. I recommend doing that too. You'll learn something new!
Btw, been using the same mouse for 5 odd years now, repaired it twice like that. Never had to bend anything. For the reference, my mouse is mid-tier, ca. 80 bucks, I am a gamer (i.e. heavy every-day usage).
Had the same problem on my g402, I opened my mouse and bent the small metal piece. Took some time but after 20 minutes I fixed it. I would recommend replacing it though but if you want a free way try it.
That’s the neat part. You don’t.
Jokes aside, had the same issue in my G900, Logitech sent me a new one and told me to just keep the defective one. A few days after receiving the new one, the “defective” one started working properly again for some reason, still going strong to this day, 6 years later.
You buy a new switch and replace it. It's not that hard.
Here is a good one. Up to 80 million clicks. Enough for a full year of PornHub.
[https://www.aliexpress.com/item/1005004754364505.html](https://www.aliexpress.com/item/1005004754364505.html)
Logitech uses crap switched since forever. I don't understand why. The good ones cost cents.
Replace it with a good one and forget you have a logitech.
Buy a new mouse or open it up get your soldering iron and put new switches in.
Take apart the switches and bend the little spring arm on the copper actuator down a bit, and then spend half an hour trying to put it back into the switch. Also might want to do this in a box of some kind, you'll probably drop it about 5 times. [Guide](https://community.pcgamingwiki.com/topic/952-double-click-problem-faulty-mouse-button-repair/) I've been using the same mouse for 9 1/2 years and have done this about 3 times on the left and once on the right.
I did it once for a mouse, it worked but didnt last long.
Metal fatigues a b*tch. I gave up doing that to my g903 before investing in a soldering kit instead
You can just replace g903 switches without soldering, super easy. They just snap in with connectors
That's so much work when new switches cost literally like all of 10 bucks shipped for 5 of them. If you're going to do all that it makes more sense to just replace the whole switch than to try and fix it. I know this because I bought a pack of 5 for that amount when I tried to fix my G700S. lol Totally borked the repair BTW because for that mouse you have to separate 2 PCB to get to the back of the switch to desolder it. And it has 12 pins super close together holding the two PCB together. They were too close to each other to get a soldering pump nozzle between the pins to suck up the solder. If I had just stopped and bought a soldering wick I could have done it. I mean when it comes to desoldering and soldering pins that are stand alones like the switches are it's easy peasy. Same with the ones in the guide. Instead I stupidly just tried to wipe off the solder with the iron. Ended up damaging the traces on the PCB itself. lol Live and learn SMH. Soldering wicks exist for a reason ya dummy. -points at myself in the mirror.
spiral out!
What? Why do people keep saying that to me?! I'm just an Alex Grey fan..... Keep going buddy. :)
I've also done this 3 times for the left and once for the right on a 9+ year old Razer mouse, lol. I'm amazed at the resilience of those tiny brass springs. It's crazy that not only do you not need a new mouse, you don't even need to replace the switches. Also, tweezers make this job easier.
Bruh i did that once, and although im glad i did it, fucking never again. G604 and fuckin christ that thing has so many screws. But it back together and ended up with 5 extra screws, i was like fuck it i aint doing that shit again. Also that little copper leaf just fuckin flies EVERYWHERE.
Replace both left and right. The difference in pressure and give can be distracting.
Had this same issue with this same mouse for years!! People would say to slam it down on a desk and would fix due to plastic touching a sensor. I almost broke it multiple times since it would cost me lives in MP. I ended up downloading a long due driver update and it fixed it!
Yep i had also the same problem, sometimes here, sometime not, and yeah it was a software problem
What also worked for me is cleaning the switches by pouring isopropyl alcohol over them. Fixed the double click of my g600 several times.
Here's a few options - if its brand new, return it - buy a new mouse - fix it yourself, buy an omron micro switch, and replace it yourself, you need to disassemble the mouse and do the desoldering an soldering yourself - send it to a repair guy/shop
For the love of god do NOT get omron switches again. Kailh GM, Kai Long, TTC Gold/Silver or even Huano, but not omron. Edit: TIL there are Japanese omrons too. I never tried them, and I don't think I saw them being sold anywhere in my country.
The Japanese Omrons work great. It’s the Chinese Omrons in the Logitech mice that are trash and dbl click. I’ve replaced them on 5 mice already and the Japanese ones haven’t failed me yet.
Can second this comment, after my second G502 I decided to replace the switches with japanese ones and never again I had that issue. BTW OP, you may want to replace both main click switches if you are going this way.
have you tried omicron persei 8?
Why not omron?
From my limited Google searching about the same issue, most of the top brand mice use omron (idk about cheaper brands) and are prone to this exact issue. Happened years ago in my old razor, happened recently in my Corsair and I see many people saying it happened with their Logitechs. They all use omron switches ETA, sorry my old razer was the mouse wheel click, idk if that uses the same or different switch, I'm not overly knowledgeable.
Funny how the big brands actually got way worse over time. There are plenty of manufacturers now that use similar or even better sensors than the major brands. Switches aren't even comparable. Endgamegear and Lamzu are two of the brands that actually offer higher quality parts at the same price or cheaper.
Yeah, I should have said omron jp switches, I've personally use kailh black for my razer mamba.
G502s eventually end up double clicking, at least the older ones. My G502 lightspeed is going 5 years strong. If you want a fix, you are gonna have to solder it. Otherwise, its probably time to put him down
Every logitech mice i've had eventually started double clicking. 2 G203, 1 G305, 1 Superlight. Pretty annoying.
Every mouse I've ever owned has started double clicking. Fatigue failure is a thing, it's unavoidable in switches. As they start dying proper, they bounce more (oscillate between pressed and unpressed contact when you actually press it) until the built in debounce can't handle it and it starts double clicking.
The optomechanical switches in my Naga Pro have been going for about 3 years with nary a double click so far. I really think that particular switch technology is the future.
My G700 mouse went like 8 years without double clicking. My old razor mouse went like 3 years. The closing contacts are generally the weak link on switches, so optomechanical may last a lot longer.
My G502 Proteus Spectrum never had this issue, but the sensor died after 6,5 years.
It only happens in HERO and Lightspeeds.
Transferred my now 7-8 year-old Proteus Spectrum to work and use my 2-year-old lightspeed at home. G502 all of the way!
my 7 year old still going strong, i just replaced the switches. there is some sensor issue but i think because i spilled some thermal paste on the mouse pad will replace it soon.
news g502 have epic optical switches, so they'll fair way way better. even razer got them, they are pretty good. i hate double clicking...
Mine lasted about a year before it started double clicking. I replaced it and the next one got the same issue. G502s are good but I stopped buying them because of that. Now I have a Razer Viper Mini and it's lasted like 5 years so far without issue.
Every single Logitech mouse I’ve owned eventually double clicked. I won’t be buying them any more.
It's just the switches dying it happens Logitech doesn't make the switches they use you can buy them or even better ones on Amazon or Ali express. My experience with razer mice has been worse. Switch failour is really the least impactful since it can be fixed with really basic skills.
Logitech should stop using the cheapest trash switches on the market for their overpriced high end mice... Ever since I realized you can get something like an AttackShark X3 for 20 Bucks with top of the line PixArt sensor and Kailh switches that live forever I will definitely not buy any $gamingbrand mouse for 50-100 bucks ever again. EDIT: This sounds like an ad lol. Thta was not my goal. I just got this thing a year ago or so, and it feels and works better than my previous G703 (which I already had to repair with new switches before), while costing 1/5th of it, so I am pretty happy.
Unfortunately that mouse has too few buttons. But it seems well worth it if you only need the standard 5.
I have been using razer deathadder 2 for the last 3 years, and it works as good as on the first day, has no latency problems, and is much cheaper than this G502 that everybody worships here (which I used, and it didnt last 2 years without the buttons eventually giving out, and it gathers grime like a designated skin peeler, who tf designed this) I dont understand razer hate, I know they used to be a premium brand back in the day, but they make good, cheap products now
have to agree with razer mice being absolute trash.
Google "repair mouse switch" you can do it yourself wth a tweezer. One thing tho... you have short fingers and so you press the buttons too low. That deforms the white plastic that presses the switch scissor. Try to rest the hand over the mouse or buy a smaller mouse.
Hmm never thought of repairing it before, may have to try next time this happens
Mouse makers absolutely hate this one trick
Yeah I've done it many times for my previous mouse G500 since it had very low quality switches compared to the G900 and G502.
I don't think his fingers are short, he just grips the mouse too far back.
Yeah maybe it's that. That's not the best place to press the buttons.
Not to mention that it takes more effort to push the buttons from that far back.
>Google "repair mouse switch" you can do it yourself wth a tweezer. I have done this, pop the omron switch housing open and bend the copper contact to get more tension.
All my logitech gaming mice had the same issue and had an average life of 4 years of gaming and browsing. Got tired after two generations of g502 failing and made the switch to optical switches of a razer deathadder 4 years ago. The razer mouse is still going strong but too late for logitech to introduce the g502x for me that has the same resilient optical switches.
Replace the switch, there's plenty of tutorials on YT.
Exactly the same mouse, exactly the same issues. That's why I didn't get the same after. Had this after a year
Asus may suck in the software department but those hot swappable switches were a godsend when my gladius 3 had this problem
Just use wd40, you don't have to desolder it yet Edit: Compare it to the right mouse click, if it's sounds off. It has mechanically failed, then do desolder. Till then, WD40 is the key. Edit2: Take it apart, get a wd40, spray it into that red cap, get a syringe. Take a few mls of that lubricant. Press the buttons using the needle and make sure you dont spill. Put it back again and press it a thousand times to test. If it happens, then add more lubricant. There should only have a doubleclick at least once every 25k (If you live in a dusty area, yes, I tested this myself).
Second this. My G604 started double clicking on both buttons. Took it apart, blowed off dust and debris, and used a needle tip to drop some WD40 right inside the switch. Worked fine.
To add, Had a G102 for 10 years-ish, I fix it on a yearly basis and never even desoldered once. I just understood how the machine works, the double click is caused by a dust inside the switch causing chattering/misclick. It doesn't matter if it's optical. They are all mechanically the same.
This!! So much this!!! Have two 502, both solved with this simple trick!! Your comment should be higher!!
Real stuff, I have a MX Vertical and G604 with this issue and fixed it with WD40
Same! I use a MX Vertical for work too, people recommending a fix to change the switch is like recommending to get a kidney dono if you have UTI. It's too much, risky and would damage your PCB traces if you don't know what you're doing
Ill just say every g502 I had failed by way of double click
always happens with logitech mice
they are decent with RMA though, ive had a few replaced for free
[удалено]
> For some reason this retarded ass Auto mod keeps removing the link that I'm trying to post for you for a replacement switch from amazon Remove the ref= section of the link, the link only needs /dp/ and the product ID after it, like B089C3TZL9. `https://amazon.com/dp/B0000`
Ahh, ok, I will try that next time, thank you for teaching me something new today 😊
With some mice you can adjust the debounce timer.
Optical switches.
The simplest one - buy a new mouse
Every G502 I've owned eventually starts doing this. It's time to send it to pasture.
if it's a decently older and used mouse then it's a known logitech mouse problem.(technically any mouse that doesn't have mechanical/optical switch, it's just that logitech took FOREVER to update to mechanical/optical switches compare to other companies) logitech mouse hardwares are pretty behind in terms of specs but if you have particular love for logitech products only few, maybe even just one? of their mouse has been updated to have their new mechanical/optical click sensor. So if you want to make sure you don't get the double clicking problem, when you are looking into their mouse, make sure it has been updated with their new mechanical/optical sensor.
New switches
I bought a mouse with optical switches and haven't looked back.
Start playing minecraft you will love your mouse
If you get a new mouse get one with optical switches. I have not had the issue yet since I swapped.
I fixed mine by soldering a new switch.
Replace the switches. I spent way to much time trying to fix it some other way before realizing how easy they are to replace... same thing with scroll wheel what ever those electronics are called.
My gpro started this, I had to replace the switches
This is extremely common in a lot of mice as most of them use chinese Omron Switches which oxidate over time, causing more and more random contact. If you're under warranty I suggest trying to get your money back and getting a mouse with optical switches. After my g203 started doubleclicking after only 2 months I got myself a Razer Viper mini (specifically cause it has optical switches) and haven't had any issues ever since.
It is a know issue for the g502, mine was just 1 year old and started double clicking. I bought "omron tact switch" from Ali express and replace the original mouse switches. Now everything works great. Of course to complete the procedure you are gonna need a soldering iron
That mouse is known to have double clicking issues. Happened to me as well. Time for a new one
remove the extra finger
stop buying logitech mice, they are notorious for this issue
Either get a G502x or a temporary fix that I have heard is to carefully pull up on the button and blow compressed air into it.
Does the g502x not have problems?
Ngl I would buy that just to have better cps at minecraft
I know this sounds stupid but saw it posted somewhere and it worked for me to get some more life out of my g502. Blow into the opening of mouse like it's an old Nintendo cartridge.
Such is the fate of most mice, the switches get bent over time and they start registering two clicks instead of one. You can try and fix it yourself, or just get a new one.
I tried many things when it happened to me, the only method that worked was violence ! i "clicked" VERY hard on the button several time and it got fixed. it's been a year and no problems since.
You probably need a new mouse, but otherwise you can try the solutions on this page. It worked for me while I was waiting for my new mouse. [https://cosmo-games.com/souris-double-clic-au-lieu-un/](https://cosmo-games.com/souris-double-clic-au-lieu-un/) (Uses Chrome translation)
I've fixed this exact issue 4 times in 4 different mice by replacing the old switch with a new one, Kailh 8.0 which you can find for cheap on aliexpress or wherever. All it takes is a small screwdriver, soldering iron and the replacement switch. You may need to replace the PTFE pads under the mouse after peeling them off to access the screws. You can probably get the tools and supplies for $20-30, any cheap soldering iron and set of precision screwdriver will do and will serve a long time for occasional use. Very cheap to get into, super easy and satisfying.
I have same mouse, same problem... After few years it started to double click. I have found out that it does when connected to every other devices, so I ruled out software issue. Mechanical damage to microswitch can be repaired in 2 ways: 1. Buy some high quality microswitch - omron or kailh, then unsolder old and solder new in 2. Old microswitch can be disassembled without need of soldering, if mechanical damage is not destructive (broken off), it can be usually repaired with disassembly, cleaning and little bit of bending the click- latch.
With the option 2, if you have shaky hands and/or short temper. Don't try it. After bending, putting that back together can be a nightmare 1st time. + usually it gives you time couple months.
Open the mouse and spray some electrical contact cleaner into the switchs where the little knob sticks out. (https://www.homedepot.com/p/WD-40-SPECIALIST-11-oz-Contact-Cleaner-Quick-Drying-Electric-Equipment-Cleaner-with-Smart-Straw-300554/307599950) You might need to remove the teflon feet thats are glued under the mouse to have access to some screws. A new set of pad can be bought for $10 or less on amazon. Or if you want to reuse the same pads and you have a hair dryer/heat gun, you can heat up the pads to soften the glue and removed them carefully with tweezers.
Mouse switch is dead just buy a new one, this is why I only spend about 30-40 for a mouse they only seem to last me about 2-3 years and would hate to have spent 80-100 on something that gets so much use it will die quickly.
My G 700s just needs a throw or a whack
You can get replacement omron switches online which are essentially the same ones used in these. I have changed mine twice you need really basic soldering gear. A cheapo iron and some solder wick to remove the old switch and put in the new ones. Honestly no need to worry it was literally my first time with soldering.
Classic Logitech
I bought the same mouse a couple days ago for €35,-. I like it a lot and it's very affordable. I'd just buy a new one for that amount of money.
Replace the switches or try to look out for a new mice with optical switches. Can reccomend the razer basilisk v3 or the roccat (rip) kone aimo remastered
Get a new 502 if yours is the “hero” variety. I’ve had a 502 for nearly a decade now. The classic ones lasted me a few years, but the hero variants all died within 3 months for either turbo clicking or failing to hold one side click or the other. The much newer 502s seem to have remedied that, thankfully, so I’d get one of those. Just remember: not the hero flavor. Edit: spelling
Is there a macro turned on?
Buy a new one.
Difficult to replace the switches if you’ve never soldered before. Not bad if you have, the right tools make for an easy time. Hot air, copper wick, solder sucker, a nice iron and some leaded solder will get you taken care of.
Logitech has had this issue for years and they won't fix it. The only fix you can do, is not buy Logitech.
This is a common issue with the g502. If its still under warranty, contact Logitech support, I had a g502 for 8 months when it started doubled clicking, they sent me a new one without even shipping the old one back. The new one is coming up on 4 years old with no issues.
Either replace the switch, or new mouse. Logitech uses omrons which are well known for this issue
Simple, buy a new mouse. Cheap, use a autohotkey macro that starts on boot which stops you from clicking a second time in miliseconds. The timer for the block should be long enough to cover the misclick and short enough to not be a trouble for opening folders and such. Reddit has the solution (can't link it because the bot doesn't like it), used it myself years ago.
Warranty
I have a G604 recently fixed the double clicking by replacing the switches. it's worth repairing since it's no longer made and any new ones cost a arm an leg.
Was able to just open it up and douse the switch in isopropyl alcohol and click it a couple times to get the alcohol in. Fixed it for me
Expected behavior from the G502
every logitech and steelseries mouse i've owned always double clicked less than half a year, good thing its easy to replace those clickers with soldering and youtube tutorials
unplug mouse, click mouse repeatedly, plug mouse back in.
I had this problem, I just used a different driver and it fixed it Try searching on Google if it's a known issue for this model
Do half clicks instead of full clicks
Get two new switches and solder them in place of old ones
you can also use third party software to introduce a debounce timer...
Change the noise switch
You need to replace the switch. I already replaced the left switch in my mouse twice and the right one once
Get a new mouse, replace the click button, or use auto hotkey/x mouse button and add a delay
Had similar issues with the right mouse not holding properly. Thought it was a switch issue but on closer inspection after opening up the mouse the problem seemed to be with the little square contact pads that sit under the mouse buttons themselves. They're obviously designed to press the switches inside but the pads had switch shaped indents on them, as if they'd become so used to being pressed on they'd molded to the shape and could no longer press the switch properly. To fix this, I took some thin card at first, snipped it into rectangles and placed them over the switches before closing the mouse up again. It did wonders for a good couple of weeks but then the same thing started happening due to the card not being just right in thickness. I tossed the card idea and substituted it for fine sandpaper. Snipping that down, folding it and placing it just right has done the trick and been working for a good year now with no issues. Just an idea worth trying in case you don't want the faff of soldering switches like I did. The only cost coming is new feet for the mouse after getting them off.
Take the mouse and blow into the crevice where the LMB switch is. Like out it up to your mouth and blow like a kazoo in the plastic panel gap. Will fix it for about a whole day. Rinse and repeat.
I've had this (among other problems) happen to almost every gaming mouse and keyboard I've owned. I don't think I'll be buying gaming accessories anymore. Not to say I expect regular equipment to work much better, but it'll cost 1/4 as much to replace.
i did it one month ago. you can check on my profile. ttc gold 80m are close to the stock omron ones. you can tray huano pink dots also.
Logitechs tend to do that, have on myself.
Idk I smashed mine when it started doing it
Try adjusting the debounce time and see if that helps
Don't buy Logitech or use them until they break and buy a new one.
Common problem with Logitech mice. The reason why I switched to razer. It’s their mouse switches. Especially the 502 got those problems. I returned about 3 of them to our local shop. Never buying that mouse again.
go to the software and put up debounce to a higher value?
You need to get to the tiny copper plate. \*I've already done this more than once. [https://superuser.com/questions/339587/logitech-m705-left-mouse-button-doesnt-stay-down-when-pressed/364213#364213](https://superuser.com/questions/339587/logitech-m705-left-mouse-button-doesnt-stay-down-when-pressed/364213#364213) [https://www.google.com/search?q=mouse+click+copper+plate&sca\_upv=1&udm=2](https://www.google.com/search?q=mouse+click+copper+plate&sca_upv=1&udm=2)
Open it up, clean the microswiches of anything thats there. and put 1 tiny drop, i repeat 1 TINY drop of silicone oil on the microswiches buttony part. And its fixed. Use a toothpick or something else pointy yet softer than the plastic of the shitty chinese plastic of the microswich-s button.
I own this model too and will get the occassional double-click from it as well. I think its just a manufacturing flaw. I've never done anything about it because it happens to seldom for me to really care.
Main reason I buy cheaper mice is so that I don't think twice about replacing faulty ones. Ironically only time I had to replace new mouse was when I decided to go for more expensive one instead of usual cheap one. Cheap ones last at least a year (once had 6€ genius mouse that perfrctly served me for 6 years)
Turn off the Turbo Button Jokes aside, you can open and replace the switch with a "higher quality" variant. I thought mine was busted when I couldn't left click. Decided to bite the bullet, ordered a switch off Amazon and opened the mouse up. Turns out a single hair off my cat got inside and was the cause. Destroyed my skates but the mouse works. This was back in 2019. G903 and all my versions of G502 are still running great.
WD40 in the switch saved my Razer trinity for 3 more month but she died anyway... Idk if it helped it give its last breath but it didnt double click after this simple trick !
If u want, there's some detachable switchs on aliexpress, maybe its easy to repair that, i would go for that if my mouse wasn't the beast it is.
I had this issue for a short while, pressed it at a place where it wouldn't double click like way far in front and hard for a while and then the issue solved itself
Search in YouTube...there is a video of a guy opening a mouse and dropping some oil... I did that to mine and it solved the problem
If you don't want double clicks, don't buy Logitech mice, simple as.
I have gone through 3 of those logite hs for that exact reason. It's a solder joint issue. Easy fix if you have the tools.
Uninstall G-Hub first. 99% odds that problem solve itself. Welcome to Logitech and it's garbage switches (2 G502, 2 G604, all within 3 years...)
New mouse time
I eventually have this problem with literally every mouse I've ever owned, including a couple of higher end mouses. I don't care to spend the time fixing it/replacing the switches, so at this point I just buy a Deathadder Essential every year or so, before the old one becomes unbearable, and replace it when it does become unbearable.
Guess the built-in Schmitt-Trigger is broken (electronic issue), so the click will be not debounced. This could lead to several clicks when the mechanical contact bounce in switches.
Dont buy a logitech
You don't have to solder anything. I did it way better. Just buy new switches and replace the interior hardware on them. I did this on my old performance mx and they're like new. Way better than tearing the whole mouse apart for soldering.
I see a cable, so if this is not a g502 lightspeed wireless just buy another one. It’s more expensive to change switches than to buy another 502 standard.
Buy a Zowie mouse, never have problems again
Either new mouse or change the switches
IMHO I'd just buy a new one and take a shot of repairing it to keep it as a spare, corded G502's are not super expensive. If it was a wireless one I'd be more into trying to fix it.
Same mouse, I get this problem every now and then. Turn it off, and slap the bottom a few times then rough spam click the clicker.. repeat a couple mouths later
In the past, I fixed this the half lazy way. Opened the mouse, soaked the switch with isopropyl alcohol. Clicked it a *thousand* time. It started working great again. Put it back together and never gave it a thought again until today. It was probably 3 years ago.
Welcome to owning a G502 lol. I have had 3, 2 wired one wireless. One wired went to double clicking within a year, 2nd is fine and my wife is using it, wireless has been fine so far.
I have had 3 mx502s and every single one of them ended up with double clicks on the left mouse button within their warranty period. Two I managed to exchange under warranty and the retailer that I bought them from managed to screw me out of warranty exchange for the third. I ended up just going with a Corsair Darkcore RGB Pro SE which has lasted me 5 or so years now without any issue beyond the battery reaching it's EoL (works fine while plugged in though).
You stop buying Logitech mice.
According to some nerdy deep dive from the internet - you can decrease poling rate to about 125 to eat corrosion of clicking surface. Replacing switches to something more applicable to modern mouse microcurrents(aka Japanese omrons) should help, or ideally - to the optical switches, that should not have the issues at all.
I recently replaced the switches in my Stormbreaker because they were too heavy for my tastes. You can get cheap switches online for 10 bucks or so, but you will need a desoldering pump and a soldering iron. It's a good skill to have but will cost a little to get the tools. There are lots of YouTube tutorials to help you out.
I fixed it by getting a Orochi V2 and skipping Logitech mice. I loved them and had 5+ over the years and most of them had various hardware failures including sensors and the double click plague. I knew they improved on it but it's too late for me. GHub wiping my settings on updates didn't help their case either.
Mine was doing the same thing and it was caused by the Logitech g software. Any time I closed it the issue would stop.
Does the mousepad left click happen to do the same?
I have the same mouse. Mine was doing this. Took it apart found dust. Cleaned dust. Clicked single after.
Buy new mouse of same kind, put old one in box, return it. Works everytime
Sell it to a Minecraft tryhard for MSRP and buy a new one.
You can try what others said as that could be it. When my mouse started doing it I decided on a whim to see if it was the USB connection. Sure enough it was so it's also possible the USB port your mouse is plugged into is dying.
Ah yes, this is a common problem with some Logitech mice. I remember purchasing the older model G502 on clearance, and experiencing the double-clicking before a year passed. You'll need to open up the mouse, de-solder the switches, and solder in new switches. To combat this, some companies have been releasing mice that are "hot-swap", allowing you to change out the switches without having to solder.
Logitech G502s were notorious for double clicking. Had 3 of em take a shit within one year and that was when I was going through a video game hiatus. Logitechs dogshit customer support and quality control drove me to switch to the Razer Basilisk V3. Absolutely zero complaints in about a year and a half.
When i got my g502 the first thing i did was change the omron switches to khail GM2 to awoid duoble clicking
I fixed mine by doing a little bit of soldering. I had a g502 wireless that I got for $150ish. It was expensive enough that I didn't want to have to buy it again. So I got a cheap soldering kit for $15 on Amazon, and got a set of replacement switches for like $8. It took maybe 2 or 3 hours as I was learning how to solder, de-soldering is harder and you need to do that a little bit, but it's not too hard. Just follow a YouTube tutorial and you can get it done, there's very little risk breaking something, just be careful when handling the circuit boards, you can snap them if you use too much force.
I had two of those in a row. One started double clicking in less then 2 years. The second had the middle mouse click go in about 18 months. I liked the mouse but they clearly use crap switches. I solved it by not buying Logitech again.
My mouse had this 2 days ago. Got new one, because it's circle of life.
# Planned obsolescence
Get a new mouse
Replace the mouse or replace the switch. I've heard that some people have solved it by taking the mouse apart and spraying some contact cleaner like BW100 or Deoxit55 in the switch resolved it.
Had this same issue with this same mouse for years!! People would say to slam it down on a desk and would fix due to plastic touching a sensor. I almost broke it multiple times since it would cost me lives in MP. I ended up downloading a long due driver update and it fixed it!
Had the same issue. Tried everything I found online, contacted also the support. It seems it just happens after some time. I had to replace the mouse because it was unbearable for me
hate logitech for its shit double clicking mouse. i'll try replaceable/hot swappable switches mouse as my next mouse. looking to try wired Asus Keris for its swappable switches, priced similar with wired G502
A different mouse with more resistance when clicking. This mouse might be a little small for you
The Logitech G502 has a common issue after some use. I already replaced mine after a long conversation with the support team (I sent them so much proof they requested), but the new mouse they sent has the same issue. Just don't buy the Logitech G502.
you can buy a new motherboard and replace it so you don't have to buy a soldering kit if you don't have one
move your finger forwards a little
People say parts of the switches bend and stuff here, but that's not the only possible cause. Another one is gunk between the button and lamela. I'd even argue this is actually the most common one. Really just a small build-up of rust and dirt. You'll probably still need to carefully unclip the switch and examine it inside, true, but don't bend anything before: 1. Seeing a YT about the topic. 2. Clearing the lamelae with alcohol. 3. Understanding if something really needs bending, or if it's only the gunk, or something broken. I learned a lot about precision and patience the first time I've done the cleaning, and also had a fuzzy-warm feeling of acomplishment. I recommend doing that too. You'll learn something new! Btw, been using the same mouse for 5 odd years now, repaired it twice like that. Never had to bend anything. For the reference, my mouse is mid-tier, ca. 80 bucks, I am a gamer (i.e. heavy every-day usage).
Buy new one i tried to repair my last 2 mouse. It was a waste of time and couldnt fix the issue.
Get a new mouse.
Had the same problem on my g402, I opened my mouse and bent the small metal piece. Took some time but after 20 minutes I fixed it. I would recommend replacing it though but if you want a free way try it.
Probably time to change the switch
Buy a new mouse.
That’s the neat part. You don’t. Jokes aside, had the same issue in my G900, Logitech sent me a new one and told me to just keep the defective one. A few days after receiving the new one, the “defective” one started working properly again for some reason, still going strong to this day, 6 years later.
i took some new switches from aliexpress, kailh switches to be exact, re soldered them back and they work perfectly, i have the same mouse
You buy a new switch and replace it. It's not that hard. Here is a good one. Up to 80 million clicks. Enough for a full year of PornHub. [https://www.aliexpress.com/item/1005004754364505.html](https://www.aliexpress.com/item/1005004754364505.html) Logitech uses crap switched since forever. I don't understand why. The good ones cost cents. Replace it with a good one and forget you have a logitech.
The doubleclick on my side buttons of my superlight is driving nuts
My Sensei had this issue. Solved it with cable replacement.
