Well, I'll be! I had the same problem with the main dial on my 5D M IV. I followed your instructions very closely and it worked! The dial works like new. Thanks for saving me a lot of money and aggravation. It cost me just over $18 for the two cans and took less than 5 minutes to fix the camera.

Another satisfied viewer who saved himself a $500 repair!

Absolute legend!! I was literally just about to open my 5dmk3 to swap out the dial for another one. Figured I would give this a go first and boom, we're back in business. All working again and only took me 5 minutes! Thanks a lot for this video!

Tried this last night, and it seems to have worked! I suspect that the contact cleaner clears out grease and such that gets between the rubber wheel and the inner, plastic wheel. Great, painless solution! Cheers!

Thank you soooo much !!! I used to apply this kind of fix for other electronic devices, but I didn’t think about using a contact cleaner for my 5d IV dials ! Grip dial and top dial are working perfectly now 👍👍👍

You're a life saver. I've been dealing with a skipping dial for 3 years now and was about to sell my 5dm4 until I saw this. Had to do it twice, but it worked!

Just done my 40D and 50D two weeks ago, job fixed Thanks.

THANK YOU KINDLY SIR !!!!! I received the products yesterday and it worked like a charm !!!! Thank again man 👍👍👍💯Respect

Another satisfied customer!! The top dial of my 5D MK IV was very hit and miss…just like described in your video. I got the two products you mentioned at Home Depot today and followed your directions. The first time did not resolve it….so had to do another round. It worked like a charm! For anyone trying this…the spray of the duster after applying the contact cleaner is an important step…I think. It resulted in contact cleaner working its way back out of the top dial opening. Wtihout this step…you might get some “pooling” of the contact cleaner inside the top dial….even though it is quick drying. Thanks for the video!!!

Thank you! I was about to take mine apart and put a new dial in and saw this…took the risk and gave it a shot. Worked like a dream and no dramas. Thank you thank you thank you!!!!

Will definitely be giving this a try. This problem has been driving me nuts.

After some time it will come back, same situation here...fixed, but only temporarily.

That worked on my EOS R! So far so good. Great tip!

Worked as prescribed!

Great fix! Worked perfect on my stubborn top dial. Thank you very much!!

Hint: sometimes the dust blower is enough, I was gonna follow this procedure on my 5D mark III and it fixed the issue with just the dust blower and a few wheel spins. I'd keep the contact cleaner as last resort.

Wow, such an easy fix. Thank you for sharing. One of our 5d bodies has been getting worse over time and this made it good as new in seconds!

Dang, i already change the dial myself and then watch your video, if only.........

I'm glad i saw your video, i was about to send my 5d4 to canon but using this method fix it. i had to do it twice and now it back to normal

thanks for the tip, everything works perfectly again, no more glitches

Good one! It happened to me every now and then, it seems I solved it using a manual air blower and isopropyl alcohol.

The products just arrived from Amazon…..fingers crossed 🤞 LOL

Hello David, just looked yr video and want to give it a try. However, I cannot find exactly the same products you are using. Not on Amazon either. Maybe because I am in the Netherlands. Can you help me out? Has the packaging been changed maybe? Thanks a lot!

went to canvas the repair at a local repair shop says it will cost me $100 went to a hardware and bought a contact cleaner for $5. Easy fix :D ty

Mine got stiffer and stiffer to turn over a pretty short time. my 7d2 shows a bit of the same but nowhere as bad as the 5d4. The wheel’s adjust function seems ok, only this damn stiffness, I feel it may even seize up although thats the gloomy view. ive seen £600 quoted for this job from Canon UK, seems Canon’s approach is to replace the entire top assembly. But Canon has always charged repair prices likely to push the owner towards buying a new camera, as a company theyre very greedy. This fault arises in several of their top models and canon clearly made no attempt to rectify the fault at design stage. if I didnt have a bag of L grade lenses Id jump ship PDQ probably to Sony kit. But cant afford to.

Thanks bro you save my camera and money

Worked great thank youuuui

This worked on my Canon R5...thanks!!!

Thank you for sharing this fix. I just had to do this twice to recover a dial as good as new.

Doesn't posting this video then saying "don't do this send to Canon" defeat the whole purpose of it? This video also only shows a temporary fix that doesn't address the root cause, all this does is make the rubber the dial is made of grip better on its inner circle. For now. Common sense(along w/your finger) should tell you the root cause of the main dial skipping or otherwise working sporadic is caused by this rubber wheel stretching & no longer gripping the internal selector firmly. There's another YT video showing a more proper & permanent fix to shorten/reconnect this dial. But it does require a bit of skill vs. spraying solvent inside your camera. Deliberate or not, it's a shame Canon switched to an expiration date rubber dial from the practically indestructible compsite plastic dial of my 1987 EOS 620 film camera which is still solid as new. It's also a shame Canon seems to have fallen prey to the game of other huge corporations by now making their cameras w/parts clearly not meant to last. They've even gone one step further in that they put service expiration dates on their high-end cameras/lenses. In other words, in 2025 they'll no longer service our 7D MkII & even L lenses so it's definitely a good idea to verify these dates & keep in mind!

You have to spray it od the sensor
