Possible Causes
Worn indoor fan motor bearings, debris in blower wheel, misaligned blower housing, dry sleeve bearings
How to Fix / Troubleshooting
Safety: Unplug the unit. Do not run the unit with covers removed.
Steps:
- Inspect blower area: Remove front cover and visually inspect the blower wheel and housing for foreign objects (plastic, paper, etc.). Remove any debris.
- Spin test: Rotate the blower by hand. Roughness, grinding, or side-to-side play indicates worn motor bearings.
- Motor replacement: If bearings are noisy, replace the indoor fan motor (and blower wheel if worn or cracked). Lubrication is usually not a permanent fix on sealed motors.
- Re-align housing: Ensure the blower housing is centered and not rubbing against the wheel.
