PVM9179FL1DS General Electric Microwave

Replaced High Voltage Diode. Very carfully due to the extream danger of a electrical shock.

Per instructions on part select.com website. But needs further repair because still doesn't heat food and pad is partially disabled.

While cooking squash for 20 min the microwave quit. No lights, nothing. Initially, I looked at fuses and tested thermostats whille leaving the unit in place over oven and removing control panel. One thermostat one base under fan showed no continuity so I replaced it just to find it was normally open so the problem remained, no power. Afte ... Read more r looking at schematic I saw the negation thermostat on the top of the megatron which would require removing the unit from the wall and disabling the unit cover , removing the vent duct. Immediately, I knew that had to be the problem since there was nothing more difficult to reach. Sure enough, after disassembling the unit, removing everything removable, I tested it and it was dead! No continuity! After replacing, everything works fine. Other than being a pain in the *** , it was pretty easy. Just a ton of screws to remove everything very obvious. The frustration is that there are two fuses, and two other thermostats right up front that would have been easy to replace but nooo. Can’t be those :-).
