GE Integrated Microwave Oven Dead

[mimo1]

I have a GE JKP76G0V1BB combo microwave / oven. The microwave went dead all of a sudden, no light, no response on the keypad, no display. We replaced the control board but did not solve the problem, still no response. The oven below is working properly. Need help to diagnose what else may be broken? Thank you!

It sounds like the monitor switch has blown a fuse... Check the fuse that is wired to the door interlock switches. If it is blown, test the door switches before replacing the fuse or it will likely just blow again...

Agree with Hiroshi. Looking at the wiring diagram, L2 feeds the microwave. The first thing on the L2 line is a 15amp fuse that would kill power to everything.

Unfortunately I don't have the wiring diagram. Any way you can tell me where the L2 line would be? And the part number for the fuse to order?

You are correct! We figured out and replaced both the monitor switch and fuse, and the microwave is back in business! Thank you for your insights!
