High‑pitched squealing or screeching noise from the unit while the fan is 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 indoor fan motor bearings, Blower wheel rubbing housing, Foreign object contacting fan blades

Safety: Unplug the unit before inspection.

Remove grille and filter: Access the blower area and visually inspect for objects rubbing the wheel.
Check alignment: Ensure the blower wheel is centered in its housing and not contacting the sides. Adjust position on the motor shaft if needed.
Spin test: Rotate the blower by hand. Roughness or grinding indicates worn bearings.
Replace motor: If noise persists and bearings are worn, replace the indoor fan motor and blower wheel assembly as a set if available.
