Microwave exhaust or cooling fan is very loud or squeals during operation.
Safety Warning
This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.
If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.
Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug the microwave.
External checks:
- Inspect the exhaust area for foreign objects or loose grille parts.
- Clean dust and grease from the fan intake and exhaust vents.
If noise persists, the internal fan motor or blade may be worn or obstructed. Accessing and replacing the fan requires removing the outer cover and working near high-voltage components; this is best done by a technician.
