If the exhaust fan on your over the range microwave does not appear to be working the problem may be with the fan motor.
Ge microwave vent fan stays on.
I ve tried unplugging it temporarily but the issue keeps coming back.
Replaced all 3 door switches and thermo fuse.
What is the solution.
Microwave has automatic fan ignition setting pre programmed to keep the unit components from over heating.
On several models of microwaves the thermostat is super sensitive causing the exhaust to run longer than needed.
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.
When i plug the power back in the fan comes on and stays on whether the door is open or not.
When it senses heat it turns on the exhaust fan.
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.
Ge microwave combo oven unit stopped heating light not turning on and turntable not spinning.
If you are cooking on the cooktop it can sense the heat and the fan won t turn off until the thermostat cools.
