Thank you for your question and I understand your concern.


The exhaust fan will turn "ON" automatically during

heavy use of the surface burners on the cook top if the fan thermostat senses too mush heat. It will come to help keep the controls cool inside the microwave control panel. It cannot be turned off manually. It will turn off automatically once it cools down. It may stay on up to 15 minutes after range and lower oven controls are turned off.

This may be the issue. If not, please reply and I will be glad to assist you further.
