How to Fix / Troubleshooting
Safety first: Turn OFF power before opening the indoor unit.

- Step 2 – Inspect blower wheel: Remove the front cover and look into the blower area for foreign objects. Remove any debris.
- Step 3 – Tighten blower set screw: If accessible, check the blower wheel set screw on the motor shaft and tighten if loose.
- Step 4 – Motor bearing check: Spin the blower by hand. If it squeals or feels rough, the indoor fan motor may need replacement.
