Possible Causes
Worn sleeve or ball bearings in indoor fan motor, misaligned blower wheel rubbing housing, lack of lubrication (non-serviceable motor)
How to Fix / Troubleshooting
Safety: Disconnect power before accessing the blower assembly.
Steps:
- Remove front cover and filter: Gain access to the blower wheel and motor.
- Check for rubbing: Spin the blower wheel by hand and listen for scraping. Adjust the wheel position on the shaft if it is rubbing the housing.
- Assess motor: If the squeal persists and comes from the motor body, the bearings are likely worn.
- Replace motor: Remove the blower wheel and motor assembly. Install a new Friedrich indoor fan motor and reassemble, ensuring proper alignment.
Note: Most modern fan motors are sealed and cannot be lubricated effectively; replacement is the proper fix.
