How do I fix the Xbox Series 2 Elite Controller Bumpers?

Yeah the Elite Series 2 was basically improved from feedback of users of the Elite Series 1

Many problems were fixed including the bumpers and the grip that also came loose after some time

Hope to get an Elite Controller one day

I totally understand and it is unfortunate that the warranty coverage has already expired. Nothing to worry, you have mentioned that you were able to temporarily fix your controller by blowing air where the bumper is.

To permanently fix the issue, I would highly recommend you have your controller fixed to your nearest electronic store as they have the right tools to check and fix the controller's left bumper.

I have similar experience before with my Xbox series controller buttons and I have it successfully fixed on one of my local electronics shops.

You can also try to fix it on your end by following the detailed instructions here on this link: (But we do not recommend a self-fix as this can possibly damage the device more.)

We cannot assist with self-repair.

My elite series 2 rb button doesnt work and i cant find a replacement button how do i fix this

Microsoft knew the controllers were defective and still sold them as a good product. they wont do anything to fix your controller because its most like out of warranty thats why the warranty was so short. The whole elite series 2 was a scam

I'm sorry to here that sadly I had my elite series 2 controller do the same thing, it started with the x button and then the bumpers, I noticed stick drift of both the sticks, sadly when I went to the store to exchange it for another one they had no
elite series 2 controllers in stock, I switched to the Razer wolverine ultimate edition and so far its a great controller
