Possible Causes

Worn fan motor bearings, Debris in fan blades, Fan blades rubbing against housing, Misaligned fan shroud

Safety first: Unplug the microwave before accessing the fan.

Step 1 – Locate noise source: Run the microwave briefly and listen to identify if the noise comes from the rear or side where the fan is located.
Step 2 – Inspect fan: Remove the cabinet and check the fan blades for debris or contact with the housing. Clean and adjust as needed.
Step 3 – Spin test: Turn the fan by hand. If it feels rough or wobbly, the motor bearings are worn and the fan motor should be replaced.
