How to Fix / Troubleshooting
Safety first: Turn OFF the breaker and wait before opening the outdoor unit. Beware of sharp metal edges.
- Step 1 – Check for obstructions: Inspect the outdoor fan for leaves, plastic, or ice buildup preventing rotation. Remove any obstructions.
- Step 2 – Spin test: With power OFF, spin the fan blade by hand. It should move freely. If stiff, the motor bearings may be failing.
- Step 3 – Inspect wiring: Ensure the fan motor connector is firmly seated on the outdoor PCB and wires are intact.
- Step 4 – Test operation: Restore power and run the unit. If the fan does not start and F5 appears, shut down the unit to avoid compressor overheating.
