Over-the-range Danby microwave fan or hood light does not work, but microwave heats normally.

Safety first: Unplug the microwave or switch off the circuit breaker before servicing the hood fan or light.

• Replace bulbs: Access the hood light bulbs from the bottom of the unit. Replace with the exact type and wattage specified by Danby.
• Fan speed settings: Try all fan speed buttons. If none work, the fan motor or control is suspect.
• Check filters: Remove and clean grease filters. Excess grease can overheat the fan motor.
• Next step: If the fan still does not run or is noisy, the hood fan motor or control board relay may need replacement by a technician.
