My Kenmore built in microwave just stopped working. Nothing works, no lights sounds or keypad response. There is power to the outlet but nothing to the microwave. I've heard there is a fuse that might be blown but don't see anyway to access the inside of the unit without taking it off the wall. Any ideas? Or if not a fuse, what might be the problem?

Could very well be the fuse, but I would say the only way to access it would be to remove the microwave from the wall. Although I could be wrong.

Be prepared to find out why the fuse blew in the first place, you might put in a new fuse and it blow that one too. Check for any shorted wires while you are in there.

If you open your microwave, make sure you discharge the capacitor before touching anything. Ive been popped by a mic capacitor before, and it does get your attention.
