I would suspect either door switches or an intermittent control circuit board, either of which can be repaired. Opening the door while cooking (without first hitting the STOP pad) is the primary cause of door switch failure over time. I have a text file on my site called "doorsw.txt" which helps in diagnosing and repairing door switch problems. You can find the file via a Google search. It will help you check and replace the door switches if you or an able friend is so inclined. In some cases, the problem is a bad connection or a bad relay on the control board. That's something we see fairly often, and we repair them for only $32.50 nationwide.

I'd say you have a contaminated or failing keypad or possibly residue on the boar dor where the keypad connects to the board.

Is it possible that some spray cleaner got into the controls?

I always recommend that users instead spray cleaner on a soft cloth then wipe the control panel.

Also, I always recommend non-ammonia cleaners since ammonia can crack and damage plastic.

Otherwise, the spray can get into the controls and lock it up or make it act odd.

If it does not dry out over time, it may need to be manually dried or blown out.

The keypad may be damaged or worn out, or control unit may be damaged.

Replace the fuse with a ceramic fuse from Home depot! costs less than $3 and it will fix the problem. I had all the same problems as everyone else, you name it my microwave had it! you must remember replace it with a ceramic fuse! not a glass one. I know people say its the switchboard and all that nonsence but I promise you, the fuse plays a majoe roll in the microwave not working properly. Even though it doesnt look broken, a junky fuse can cause your appliance to do very strange things. I replaced mine 6 months ago and it works like its fresh out of the box.

You will need to remove the oven from the wall and remove the outer cover.

If for some reason you don't have yours, you can download your owner's manual and installation instructions free from this page.

These models use halogen lamps. You must not touch halogen types with your bare skin, as the oils will shorten the bulb life.

You should be able to get one from a home center or local appliance parts store.

If you order it online (from the link above) it is part # 4375348.

When I opened up the microwave cover, noticed that the door latch mechanism was worn and not holding up the interlock switch. A thick piece of tape on the worn piece of plastic and microwave was back to working (I had symptom of the timer counting down without the microwave turning on)
