Amica Cooling Fan or Convection Fan Bearing Wear

Microwave fan is very loud or makes grinding noises 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 fan motor bearings, Foreign object in fan blades, Loose fan mounting, Bent fan blade

Safety: Unplug before accessing fan assemblies.

Identify fan: Determine if the noise is from the rear cooling fan or the internal convection fan (if equipped).
Inspect blades: Remove obstructions such as insulation, wires, or debris touching the blades.
Check mounting: Tighten any loose screws securing the fan motor.
Spin test: Rotate the fan by hand; roughness or play indicates worn bearings.
Replace motor: If noisy, replace the fan motor assembly with the correct Amica part.
