Kitchenaid Refrigerator Touchpad not responding, both sections warm

"Most of the time, the culprit in the case of both frig and freezer not cooling sufficiently (with your model) will be the “compressor start device and capacitor”. This part runs between $45-$60, depending on where you get it, and you probably should get someone qualified to handle the replacement.

Also, according to what I’ve read on the non-responsive touch pad issue, as odd as it may sound, it appears replacing the water filter (located upper right, at the back, inside the frig compartment) is the most common fix. But be aware this could also be an issue with the control board. Again, you may want to have someone qualified to help make this determination.

Good luck."
