If the SMH8165STE does not appear to have power, please confirm that it is plugged into an appropriate dedicated outlet that meets the following specifications: 120V, 60 Hz, 20 amps. Try cycling the power by unplugging then replugging the microwave, or turning the circuit breaker off and on. To confirm the outlet is powered, try plugging in a different appliance (like a clock or blender) to see if it works.
If the microwave still doesn't power on, it will 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.
