Possible Causes
Failed outdoor fan motor, Faulty fan capacitor (on AC motors), Obstructed fan blades, Faulty outdoor PCB fan driver
How to Fix / Troubleshooting
Safety: Isolate power and wait for the fan to stop before working on the outdoor unit.
Steps:
- 1. Check for obstructions: Inspect the outdoor fan guard and blades for debris, ice, or foreign objects. Remove carefully.
- 2. Spin test: With power off, spin the fan by hand. It should rotate freely. Stiffness indicates bearing failure.
- 3. Inspect wiring: Check the fan motor connector and wiring harness to the outdoor PCB for damage or loose connections.
- 4. Capacitor check (AC motors): If your Baxi model uses a separate fan capacitor, a technician can test and replace it if weak.
- 5. Replace fan motor: If the motor is seized or electrically open, replace it with the correct Baxi outdoor fan motor.
