Frigidaire Microwave Fan Runs When Door Is Closed

The problem is the primary interlock switch is supposed to be open when the door is opened which would effectively remove the 120vac from the cooling fan.

Frigidaire microwave fan runs when door is closed.

My microwave same model after 2 years runs as soon as i close the door intermittently. It s not actually activating the magnetron as nothing warms up. I was actually looking for an answer here. Once the do read more.

A malfunctioning circuit board may cause the control panel to run the light to turn on the fan to function and the turntable to rotate all signs that the microwave is working but the food may not be actually heating up. The microwave still lights the inside lamp and the fan still blows. The microwave works when cook time is entered but will not shut off until door is opened. The components that could stay on when the door is open but the door switch isn t working are the fan motor stirrer motor and interior light.
