Possible Causes
How to Fix / Troubleshooting
Safety first: Turn off power to the indoor unit at the breaker before removing the blower door.
Steps to check:
- 1. Access blower assembly: Remove the blower door on the Goodman furnace or air handler to expose the blower housing.
- 2. Inspect blower wheel: Look for screws, insulation, or other debris lodged in the wheel. Remove any obstructions.
- 3. Spin blower by hand: Rotate the wheel. If you feel grinding or hear squealing, the motor bearings may be failing.
- 4. Check alignment: Ensure the blower housing is properly seated and not twisted, which can cause the wheel to rub.
When to call a professional: Blower motor or wheel replacement and rebalancing should be done by an HVAC technician to ensure proper airflow and quiet operation.
