Indoor Keeprite air handler makes loud squealing or grinding noises when running.

Safety Warning

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 blower motor bearings, Loose blower wheel on shaft, Debris in blower housing, Bent blower wheel

How to Fix / Troubleshooting

Safety first: Turn off power at the breaker. Blower wheels can start unexpectedly if power is restored.

Step 1 – Access blower: Remove the blower compartment panel.
Step 2 – Inspect wheel: Check that the blower wheel is centered and not rubbing on the housing. Tighten the set screw on the motor shaft.
Step 3 – Clean housing: Vacuum out dust and debris that may be contacting the wheel.
Step 4 – Check bearings: Spin the wheel by hand. If it grinds or has excessive play, the motor bearings are worn and the motor should be replaced.
