Whynter Fan or Pump Bearing Wear

High-pitched squealing or whirring noise while 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

Worn condenser fan motor bearings, Failing circulation pump (on some models), Fan blade rubbing housing

Safety: Unplug the unit before touching any moving parts.

Steps to fix squealing noise:

Locate noise: Determine whether the sound comes from the rear (condenser fan) or inside (circulation pump).
Inspect fan: Check that the fan blade spins freely by hand and is not rubbing against the shroud. Adjust position if needed.
Check for play: Wiggle the fan shaft; excessive play indicates worn bearings. Replace the fan motor.
Circulation pump: If equipped, listen near the pump. If noisy or rough, replace the pump assembly.
