Possible Causes
Worn blower motor bearings, Blower wheel rubbing against housing, Misaligned motor mount, Debris lodged between blower wheel and shroud
How to Fix / Troubleshooting
Safety first: Unplug the unit. Do not run the fan if grinding is severe; it can cause further damage.
Steps to address squealing/grinding:
- 1. Access blower assembly: Remove the front panel and any internal covers to expose the indoor blower wheel and motor.
- 2. Check for rubbing: Spin the blower wheel by hand and listen for scraping. Adjust the wheel position on the motor shaft so it is centered in the housing.
- 3. Remove debris: Clear any objects or heavy dust buildup from the blower and housing.
- 4. Evaluate motor bearings: If the squeal persists and the shaft feels loose or rough when turned by hand, the motor bearings are likely worn. Replace the indoor fan motor with an OEM Insignia motor.
- 5. Rebalance and test: After reassembly, run the unit and verify smooth, quiet operation.
