Thank you for the question. Please make sure your microwave is connected to a dedicated 120V/60 Hz/20-amp power supply, then try unplugging the microwave and plugging it in again, or turning the circuit breaker off then on. If you continue to have the delayed response times you've described, your microwave may require service to determine the cause and find a solution. 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.
