Microwave stopping working

The microwave was working fine until today. I tryed to heat up something and it ran for about 1 minute and and shut off causing my fuse box to trip off. The unplug the microwave and turned the fuse box to the on position and then replugged the microwave and now it is not coming on at all.

In this one, the most likely causes are the inverter or magnetron, but it really will need an experienced troubleshooter. Due to the lethal voltages involved, I do not recommend that a person without training and experience ever work on these models. You should be able to locate a Panasonic-authorized servicer here: http://www.pasc.panasonic.com/WhereTo/FindServicer.asp?Pass=1 I would mention the exact symptom when you call so the technician can bring a new inverter with him when he comes out to repair it. Might save you having it pulled into the shop.

check the fuse on the microwave. if its busted, something shorted out in the oven that tripps off your breaker. it could be your inverter.
