Possible Causes
How to Fix / Troubleshooting
Safety first: Turn off power at the outdoor disconnect. Do not attempt to spin the fan with power on.
Steps to try:
- Inspect fan blade: Remove the top grille if necessary and check for sticks, leaves, or ice blocking the fan. Ensure the blade is not cracked or loose on the shaft.
- Spin test: With power off, spin the fan blade by hand. It should rotate smoothly. Resistance or grinding indicates motor bearing issues.
- Check wiring: Verify the fan motor connector is fully seated on the outdoor PCB and wires are not damaged.
- Clean area: Remove debris around the outdoor unit to prevent future obstructions.
When to call a pro: If F7 persists, the outdoor fan motor or outdoor PCB will need diagnostic testing and likely replacement.
