Doug for Model Number PNM1971SR1SS GE Profile OTR Microwave After a cycle tried to run another cycle and entire uwave went dead. No lights, display, no buttons work, nothing. 1) Checked outlet w/ circuit tester and another appliance - Outlet OK 2) Checked both fuses with DMM - Both measured <2 ohms - Fuses OK Thinking either a bad TCO somewhere or the PCB is bad. Thoughts ?
