Ge Microwave Vent Fan Stays On

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 vent fan stays on.

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. Microwave model me21k7010ds fan turns itself on randomly random messages flash on the input screen turnable off turntable on press ok etc and beeping for no reason.

When i plug the power back in the fan comes on and stays on whether the door is open or not. Replaced all 3 door switches and thermo fuse. I ve tried unplugging it temporarily but the issue keeps coming back. 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. 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.
