Possible Causes
Worn blower motor bearings, blower wheel rubbing housing, misaligned blower shaft, debris in blower housing
How to Fix / Troubleshooting
Safety first: Unplug the unit before accessing the blower assembly.
Steps:
- 1. Remove front cover: Access the indoor blower wheel and motor.
- 2. Inspect blower wheel: Check for rubbing marks on the housing and ensure the wheel is centered on the shaft and not wobbling.
- 3. Clear debris: Remove any foreign objects or heavy dust buildup from the blower blades.
- 4. Check motor play: Gently move the blower motor shaft; excessive side-to-side play indicates worn bearings.
- 5. Replace motor and/or wheel: If the motor squeals or grinds when spun by hand, replace the indoor blower motor (and blower wheel if damaged) with Koldfront-compatible parts.
