How to Fix / Troubleshooting
Safety first: Turn OFF power at the outdoor disconnect before inspecting.
Steps:
- 1. Inspect fan blade: Look for bent blades or contact with the fan shroud. Gently straighten minor bends if safe.
- 2. Check for debris: Remove sticks, leaves, or foreign objects from the fan area.
- 3. Spin fan by hand: If it feels rough or wobbly, the motor bearings may be failing.
- 4. Listen to compressor: A loud knocking or grinding from the compressor itself indicates internal damage.
- 5. Call a technician: Fan motor or compressor replacement should be done professionally.
