Hi all,
Got a GE Profile PEM31SM3SS Profile microwave go off (no power) after one or few uses. It could run 1 cycle like a 1 minutes or 2/3 then got no power. or it could last few cycles with the same issues. Unplugged/replug or flip the breaker normally bring it back until the next time. I tried different outlet on different breaker and the result is the same. It is seems to start this issue when I added another duplex receptacle to the same box, go from a double to quad, same circuit, which I don't think would cause this type of issue. When the microwave got no power, the outlet still got power.
Thanks,

Hi,

Possible trouble makers:

Main power wire loose or burnt.
Bad cavity thermostat or it's wiring.
Bad fuse holder/noise filter board.
Fuse.
Bad main pcboard.

Someone will need to remove the outer cover to have a peek.
But, keep in mind:
Microwaves are very dangerous, they can still shock you even unplugged!!
