GE microwave not working/unresponsive

I have a GE Over-The Range Microwave (model#PVM1870SM3SS) that has suddenly stopped working and is completely dead. I heated pizza up, opened the door and took it out. As I was about to shut the door everything went blank. The interior light went off and the display panel went dark. Its completely dead. I checked the circuit breaker and it was fine. I unplugged it from the wall and plugged it back in but still get nothing. Can you please advise me on what to do next? Any help or advice would greatly be appreciated.....Thank You

 

Welcome to the forums.

Be sure to try it in a different/confirmed working receptacle.

That would be indicative of a problem with a door switch.
Your unit has a main protection fuse as well as a thermal safety fuse.
The logical step is to check the internal fuse next. This requires unmounting the unit.

Microwave repair is technically not a DIY repair due to the high voltages found inside.

The following link illustrates checking the fuse....

Unplugged, it is as safe as a flashlight battery. An internal fuse is blown and the High voltage power diode is likely shorted. The cover is fairly easy to remove to access those parts. Online appliance part dealers have exploded views and part lists to help locate same. A VOM ( volt-ohm meter) is very helpful to check if fuse is blown and diode shorted out or even the cord cut between plug and MV. If you replace fuse it will likely blow again without finding out why. Don't even play inside with it plugged in - that hi voltage can change a VOM to trash. In five years that was the same problem with 5-6 friend or family's unit and I'm just a DIY or else. LOL
