Ge Microwave Vent Fan Stays On

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.

Ge microwave vent fan stays on.

On several models of microwaves the thermostat is super sensitive causing the exhaust to run longer than needed. Ge microwave combo oven unit stopped heating light not turning on and turntable not spinning. I ve tried unplugging it temporarily but the issue keeps coming back. Microwave automatic fan feature all over the range microwaves have an automatic fan feature to help protect the electronic components and also helps the cooking area get rid of excess heat.

If you are cooking on the cooktop it can sense the heat and the fan won t turn off until the thermostat cools. Microwave has automatic fan ignition setting pre programmed to keep the unit components from over heating. Replaced all 3 door switches and thermo fuse. 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.

The exhaust fan thermostat is usually the failed component. If the exhaust fan on your over the range microwave does not appear to be working the problem may be with the fan motor. What is the solution.
