Ge Microwave Vent Fan Stays On

When i plug the power back in the fan comes on and stays on whether the door is open or not.

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. On several models of microwaves the thermostat is super sensitive causing the exhaust to run longer than needed. If you are cooking on the cooktop it can sense the heat and the fan won t turn off until the thermostat cools. Ge microwave combo oven unit stopped heating light not turning on and turntable not spinning.

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. 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. Replaced all 3 door switches and thermo fuse.

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. When it senses heat it turns on the exhaust fan. I ve tried unplugging it temporarily but the issue keeps coming back.
