How to Fix / Troubleshooting
Safety first: Unplug the freezer before accessing the control panel or sensor wiring.
- Check installation location: Ensure the Fagor freezer is not installed in a garage or unheated space outside the specified ambient temperature range.
- Inspect ambient sensor: Locate the ambient NTC sensor near the control panel or front grille and check for damage.
- Measure resistance: Test the sensor at room temperature and replace if readings are out of specification.
- Relocate appliance: If the room is too hot or cold, move the freezer to a more suitable location.
- Control board: Persistent F5 with a good sensor and proper environment may indicate a faulty control board.
