I'm sorry to hear you're having this issue. The circuit breaker that may need to be reset would be in your house, not in the microwave. In addition, the SMH9151 should be plugged into a dedicated 20-amp circuit. If yours is, and the microwave will not turn back on once you've reset your home's circuit breaker, it may require service. 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.
