PEB7227AN3DD General Electric Microwave

Hello Dennis, Thank you for your inquiry. For safety reasons, since the microwave capacitor can still store electricity even when the microwave is unplugged, it is usually advised that you discharge the capacitor before any attempt at repair. We have included a link on how to do so. First, check to see what else is plugged into the same circuit, as if too many items are plugged into the same circuit that the microwave oven is on, it can cause an overload-make sure that the microwave has its own dedicated circuit of 20 amps on the breaker, and try plugging the microwave into other circuits to see if the same issue happens. If the issue happens when you use a different plug-in, then the parts that can cause this issue are one of the door switches, the diode, the transformer, or the capacitor. You can test the parts with a multimeter. Good luck with your repair.
