Possible Causes
How to Fix / Troubleshooting
Safety first: Turn off power and wait for the indoor fan to stop completely before opening the front cover.
Steps to try:
- Check for obstructions: Remove the front panel and filters. Inspect the cross-flow blower wheel for foreign objects (plastic, insulation, toys) that may jam rotation. Remove any obstructions.
- Spin the blower by hand: It should rotate freely without grinding. If stiff or noisy, the motor bearings may be failing.
- Inspect wiring: Locate the indoor fan motor connector on the PCB and ensure it is fully seated. Check for damaged wires.
- Clean dust buildup: Heavy dust on the blower can overload the motor. Use a soft brush and vacuum to clean the wheel and housing.
When to call a technician: If the fan still does not start or E6 returns, the DC fan motor or the indoor PCB driver circuit likely needs replacement.
