Vent Won't Turn Off - Over-the-Range Microwave

Possible Solutions

Fan running during cooktop usage

The microwave oven’s cooling fan (on some models), which is separate from the vent fan, automatically comes on during microwave oven operation to cool the microwave oven. It may also automatically come on and cycle on and off to cool the microwave oven’s controls while the cooktop below is being used. It may stay on for up to 1 hour to cool the microwave oven. When this occurs, the vent fan cannot be turned off.

Has the fan been on for 4 hours?

The vent fan will automatically turn off or shut off after 4 hours.  

Fan running during cook function

The vent fan will automatically turn on during any cook function (on some models), acting as a cooling fan to protect the microwave.
