Fagor Fan or Motor Bearing Wear

Microwave emits unusual high-pitched squealing or chirping noise during operation.

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

Worn cooling fan bearings, Worn turntable motor bearings, Foreign object contacting fan blade, Loose fan shroud

Safety: Unplug before inspection.

Isolation:

Run the microwave briefly without the turntable (if allowed) to see if noise changes.
If noise persists regardless of turntable, the cooling or convection fan is likely at fault.

Internal fans or motors with worn bearings should be replaced by a technician to prevent failure and overheating.
