Kismile Worn or Contaminated Fan Motor Bearings

Fan noise is loud or squealing 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

Dust buildup on fan shaft, Dry or worn fan motor bearings, Fan blade out of balance, Fan hitting wiring harness

Safety: Unplug the unit before servicing the fan.

Clean fan assembly: Remove the rear panel and clean dust from the fan blades and motor housing.
Check for contact: Ensure no wires or insulation are touching the fan blades.
Lubrication (temporary): A small drop of light machine oil on the fan shaft may temporarily reduce noise, but if noise returns, replace the motor.
Replace fan motor: If squealing persists, install a new condenser fan motor and reuse or replace the fan blade as needed.
