How to Fix / Troubleshooting
Safety first: Turn off power at the outdoor disconnect before working on the fan.
Steps:
- Check for obstructions: Inspect the outdoor fan blade for sticks, leaves, or ice buildup preventing rotation.
- Spin test: With power OFF, spin the fan blade by hand. It should rotate smoothly.
- Restart and observe: Restore power and command cooling. If the compressor runs but the fan does not or runs erratically, shut power off again.
Repair: Replace the outdoor fan motor if it fails to start or has excessive play/noise. If a new motor does not resolve F7, the outdoor control board may be defective and should be replaced by a technician.
