I'm sorry to hear the exhaust vent on your SMH9151 microwave is not working. If the microwave is connected to a dedicated 120V, 20-amp power supply, and the exhaust fan motor does not turn on when you press the Vent Hi/Lo/Off button firmly, your microwave will likely require service. To initiate service through Samsung, please submit an online service request through the link below, or call 800-SAMSUNG to speak with an agent who will be happy to assist you.
