How to Fix / Troubleshooting

Safety first: Disconnect mains power before accessing sensors or control boards.

Identify which sensor: Refer to the user manual or service documentation to determine whether the error refers to fridge, freezer, or ambient sensor.
Access sensor: Remove the relevant interior cover or rear panel to expose the sensor. Carefully pull it out if it is in a sleeve.
Inspect wiring: Check for cuts, pinched wires, or corrosion at the connector. Repair or replace damaged wiring.
Replace sensor: Install a new OEM NTC sensor, routing the wire as originally to avoid contact with moving parts or sharp edges.
Reset and test: Restore power and clear the error (if required by button sequence). Monitor displayed temperatures for stability.
If error persists: The main control board may have a defective input channel and will likely need replacement by a professional.
