Chefman Fan Motor Bearing Lubrication Failure

Air fryer makes a high-pitched squealing noise when running.

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

Dry sleeve bearings in fan motor, Misaligned fan shaft, Dust buildup in motor bushings

Safety first: Unplug the fryer and allow it to cool.

Access fan motor: Remove the housing to expose the fan motor.
Clean dust: Use compressed air or a soft brush to remove dust from the motor vents and shaft area.
Check alignment: Ensure the fan blade is seated fully on the shaft and not forcing the shaft sideways.
Motor replacement: Most sealed fan motors in Chefman units are not designed for lubrication. If squealing persists, replace the fan motor assembly.
