Check the power supply: Ensure the microwave is plugged in, and test the outlet with another device. If the outlet is faulty, reset the circuit breaker or replace the outlet.
Inspect the circuit breaker: Locate the circuit breaker panel and check if the breaker for the microwave is tripped. If so, reset it. If it continues to trip, consult a professional.
Test the door switch: Open the microwave door and press the door switch with a small tool. If the microwave operates when the switch is pressed, the switch may need to be replaced.
