How to Fix / Troubleshooting
Safety: Unplug the microwave before cleaning vents or moving the unit.
User-level steps:
- 1. Identify noise source: Listen carefully to determine if the noise comes from the rear, side, or top where the fan is located.
- 2. Clean vents: Use a vacuum or brush to remove dust and debris from vents that may contact the fan blades.
- 3. Check for foreign objects: Ensure no small items have fallen into external vent openings.
If the squealing persists, the cooling or convection fan motor likely has worn bearings and should be replaced by a technician.
