How to Fix / Troubleshooting
Safety: Unplug the unit before working near the fan.
- Check for blockage: Remove the front grille and filter. Inspect the blower wheel for foreign objects or heavy dust buildup. Clean thoroughly.
- Spin test: Try spinning the blower by hand. If it is stiff or seized, the indoor fan motor likely needs replacement.
- Capacitor: Inspect the fan capacitor (if separate). Replace any bulged or leaking capacitor with the correct value.
- Wiring: Verify all fan motor connectors are secure and not burnt.
- Replace motor: If the motor does not run even with proper voltage and a good capacitor, replace the indoor fan motor assembly.
