Dennis for Model Number PVM1790SR1SS My microwave went totally dead. No clock, nothing. We were cooking potato's with the convection and it just quit in the middle of this. I checked the plug, the main fuse, and the thermal fuses. They all appear good. Is it very common for the main board to go out? Help! Thanks
