I'm sorry to hear you're having trouble with your SMH7178STE microwave. After receiving an error code, you can try cycling the power by unplugging the microwave, or turning the circuit breaker off then on again. If the error code returns or the problem persists, your microwave 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.
