Thanksgiving night my GE Profile Spacemaker XL1800 above the oven microwave died. No digital display, nothing. I unplugged it and plugged back in and it seemed to reset itself. Next day, I was heating something and it went dead again in the middle of heating. Did the same thing, was able to finish heating my food, but then it went dead again. I don't want to keep messing with it, in the case that this is some safety feature, preventing my microwave from starting on fire. Has anyone had this experience, and what is the repair that needs to be made?
