Possible Causes
Seized outdoor fan motor, Fan blade jammed by debris, Failed fan motor hall sensor, Faulty outdoor PCB fan driver
How to Fix / Troubleshooting
Safety first: Turn off power at the outdoor disconnect before touching the fan or removing panels.
Steps to try:
- Clear obstructions: Remove any visible debris, ice, or objects blocking the fan blade.
- Manual spin test: With power off, spin the fan blade. If it does not spin freely, the motor bearings may be seized and the motor should be replaced.
- Check wiring: Inspect the fan motor harness and connector for damage or loose pins.
- Restart test: Restore power and run the unit. If the fan still does not start and H6 returns, the motor or PCB is faulty.
When to call a pro: Replacement of the outdoor fan motor or PCB should be done by a technician.
