Ge Microwave Vent Fan Stays On

I ve tried unplugging it temporarily but the issue keeps coming back.

Ge microwave vent fan stays on.

If the exhaust fan on your over the range microwave does not appear to be working the problem may be with the fan motor. When it senses heat it turns on the exhaust fan. On several models of microwaves the thermostat is super sensitive causing the exhaust to run longer than needed. The exhaust fan thermostat is usually the failed component.

The fan motor is located at the top rear of the microwave and exhausts the air into the duct system or re circulates into the room through the charcoal filter depending on the installation. The built in thermostat automatically turns the vent fan on if the unit is too hot and will not turn off until the microwave is cool again. What is the solution. Ge microwave combo oven unit stopped heating light not turning on and turntable not spinning.

Microwave has automatic fan ignition setting pre programmed to keep the unit components from over heating. Replaced all 3 door switches and thermo fuse.
