Ge WB27X10194 Thermostat OEM Part

Follow the trio ubshooting flow chart inside of the microwave panel - and read articles on this website. Turned out to be a thermostat that had popped and gone bad. Replace the thermostat and it is good to go.

Changed blown 20A fuse and thermal fuse.

Originally thought maybe a fuse but first thought to look on the internet. Found this website which was very helpful. Turned out the thermostat on top of the microwave was the problem. Ordered the thermostat and spares for the future. Replaced the thermostat and problem solved. This item is inside so the cover had to be removed. While removing the cover I found a wiring diagram inside the Display Module. It was helpful although I had to trace the wires to locate the thermostat. Turns out microwaves are not that complicated.

I found a blown fuse and an open thermostat, which I ordered. The new thermostat tested open as well. I called AppliancePartsPros.com and they informed me that it was a "normally open" thermostat that would close and turn on a fan if the unit got too hot. So, I continued with the diagnosis and found an open diode and a shorted electrolytic capacitor. I was able to obtain those parts locally. With a new fuse, diode, and capacitor installed, the microwave was once again operational. I appreciate the technical support from Appliance Parts Pros.
