Possible Causes

Worn blower motor bearings, Blower wheel rubbing against housing, Foreign object in blower wheel, Misaligned blower assembly in Goodman air handler/furnace

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.
