How to Fix / Troubleshooting
Safety: Unplug the freezer before cleaning or accessing the compressor compartment.
Steps:
- Check installation: Ensure there is adequate ventilation around the freezer, especially at the rear and sides. Follow Fisher & Paykel clearance recommendations.
- Clean condenser: Remove the rear lower panel and vacuum dust and lint from the condenser coils and surrounding area. Use a soft brush to avoid damaging fins.
- Verify condenser fan: With power briefly restored, confirm the condenser fan runs whenever the compressor runs. If the fan is not running, unplug the unit and replace the condenser fan motor.
- Ambient temperature: Ensure the freezer is not installed in a very hot space (e.g., unventilated garage in summer) beyond its rated climate class.
- Persistent F9: If the code returns after cleaning and verifying airflow, the compressor may be overheating due to internal faults or low refrigerant. This requires a qualified refrigeration technician.
