Latisha, I wouldn't assume it is the keypad itself. Does it light up or do anything at all? If it seems totally dead that suggests some problem with the power supply to it, which is inside the cabinet. So here is some advice. Do not attempt to access the innards, as there are lethal voltages in there, even when the power is off.

But not all is lost. The entire wiring diagram for the serviceable portion of a microwave oven would fit on the bottom of your shoe. So, microwave ovens are relatively easy to trouble shoot for an experienced technician, and many problems that seem really bad to the user, are actually not very expensive to diagnose and fix. So, take it to a qualified repair station you trust and get some $$ numbers from them. You may find it worth fixing. If not you can always just trash it.

SOURCE: GE Microwave Model: JVM1540DN1BB Keypad appears to work... but Microwave doesn't work

The problem is more than likely in the microprocessor control board, sometimes a bad relay, or poor solder points.

LED not working


see this causes and fix it. God bless you
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.

Sharp Carousel Microwave - R1481 keypad doesn't work


No! I'am afraid not, the problem is in the keypad control board, the whole assembly must be replaced, the part alone will cost around $100.00 or more depending on make and model.

Can't use the microwave at all


you have either a bad keypad or control board.

If you have operation of some buttons and not others its the keypad. if you have no operation out of the buttons at all you have a bad control board.

If you turn your microwave on and it sets and the timer counts down you have a bad interlock switch..

please let me know exactly what your microwave does when you set the cook time
