How to Fix / Troubleshooting
Safety: Turn off power to the furnace/air handler before opening the blower compartment.
- 1. Access blower assembly: Remove the blower access panel. Use a flashlight to inspect the blower wheel and motor.
- 2. Check for debris: Look for insulation, plastic, or other objects rubbing against the blower wheel. Remove any foreign objects.
- 3. Inspect blower wheel: Spin the wheel by hand. It should rotate smoothly without wobble. If it scrapes the housing, the wheel may be bent or misaligned.
- 4. Motor bearings: If the squeal or grinding persists and the motor shaft feels rough when turned by hand, the motor bearings are likely failing and the motor should be replaced.
- 5. Professional balancing/replacement: A technician can replace the blower motor and wheel and ensure proper balance and alignment.
