Possible Causes

Dry or failing blower motor bearings, Blower wheel rubbing housing, Loose blower wheel on shaft

Safety: Turn off power to the air handler.

Access blower assembly: Remove the blower compartment door. Inspect the Luxaire blower wheel and motor.
Check for rubbing: Spin the wheel by hand and listen for scraping. Adjust the blower housing or wheel position as needed and tighten set screws.
Motor bearings: If the squeal comes from the motor and persists, the motor bearings are likely failing. Replace the blower motor with the correct Luxaire replacement.
