How to Fix / Troubleshooting
Safety first: Unplug the cooler before working inside the lower compartment.
- Confirm zone mapping: Verify that F2 corresponds to the lower zone on your model.
- Access lower zone sensor: Remove lower zone shelves and the interior panel or cover where the sensor is located (typically rear wall).
- Inspect sensor: Ensure the sensor is properly clipped and not hanging loose. Check for visible damage or corrosion.
- Check harness and board connection: From the rear, inspect the lower zone sensor connector on the main control board and ensure it is fully seated.
- Replace sensor if needed: Install a new "Phiestina lower zone temperature sensor" if the old one is damaged or tests open/shorted.
- Reassemble and test: Put panels and shelves back, restore power, and confirm that F2 clears and the lower zone holds temperature.
