I recently had some electrical problems on the same circuit as my microwave (a Kitchen Aid KHMS1850) the microwave went on and off a few times now it is completely dead. I plugged it in directly to a good outlet and it still doesn’t run. I replaced the fuse and that was not the problem. Also, how do you access the internal parts taking out the complete unit?

I found the fuse and it the continuity checks ok with my ohm meter. The microwave is dead and I don't know what to check next, any suggestions?
