Is This the Right Part?

Common Symptoms

• Unusual or louder-than-normal fan noise during microwave operation.
• Cooling fan fails to spin.
• Microwave shuts off unexpectedly during operation because of overheating.

Check Before Replacing

• With the microwave fully assembled, observe whether a cooling-fan sound is present during a normal cooking cycle; do not remove panels or access internal wiring.
• Confirm the symptom is not limited to the separate hood/exhaust-fan function or an airflow restriction before attributing it to this internal cooling-fan motor.
• If the microwave is unresponsive, perform Whirlpool’s basic one-minute power reset by unplugging it or switching off its circuit breaker, then restore power.
• Do not perform energized internal voltage or continuity tests unless you are a qualified appliance technician.
