All of a sudden, no power, no lights, NOTHING!
Took 5 screws out to get the top/sides loose and found a blown fuse right near where the power cord goes in. Gonna get a new fuse tomorrow and replace it. I think it might have been a power glitch that blew the fuse. I hope it doesn't blow again when I turn it on, because that will mean something more complicated is wrong, requiring professional service.

If the microwave is on the same circuit as the refrigerator, it's possible that the micro was turned on just as the refer compressor kicked on. i've seen that situation pop a fuse in microwaves many times - make sure you get a ceramic slo-blo fuse
