Clatronic Fan or Turntable Motor Bearing Wear

Microwave emits a high-pitched squeal 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 motor bearings, Worn turntable motor bearings, Debris contacting fan blades, Loose fan shroud

Steps:

Isolate source: Listen carefully to determine if the noise comes from the top/rear (cooling fan) or bottom (turntable motor).
Check turntable: Remove the glass tray and roller ring, then run briefly with a cup of water. If the noise disappears, the issue is with the turntable assembly.
Clean vents: Dust or debris in the fan can cause squealing. Clean vents thoroughly.
Technician replacement: If the noise persists, a technician should inspect and likely replace the cooling fan motor or turntable motor.
