proceed with common sense tech. God bless you
Touchpad dead If you have a stuck key or non-responsive key, most of the time you will have to replace the keypad for this microwave oven repair. If your keypad is connected to your control board by a flat ribbon wire, try disconnecting it and clean the silver contacts with an ordinary pencil eraser. After cleaning, plug it back in and try it. If it doesn't fix it, replace the keypad unit. Some units actually have keypad tests to confirm your diagnosis of a bad key.If your keypad and control is the same unit, replace that unit. Another note, unlike stove/oven keypads and controls, most microwaves do not have error codes or tests to distinguish whether it is truely the keypad or control. Most of the time, it is the keypad that needs replacing, but a small percentage of the time it can be the control. Check the tech sheet if they can point you to the right part.
