Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. First I’ll need some more info so I have a more complete picture of you situation.

Have you checked where the exhaust terminates outdoors? A blocked vent can cause an outage. Are you getting an error message on the display?
