Possible Causes
Faulty fridge NTC sensor reading too warm, Stuck electronic thermostat on PCB, Incorrect temperature setting, Damaged air damper stuck open
How to Fix / Troubleshooting
Safety: Unplug before accessing sensors or control boards.
Steps:
- Check settings: Ensure the fridge temperature is not set to the coldest level. Adjust to recommended (around +4°C).
- Relocate sensitive items: Avoid placing delicate foods directly in front of cold air vents.
- Inspect fridge NTC: Access the fridge temperature sensor and check for dislodging or damage. Replace if suspect.
- Check damper: Ensure the air damper is not stuck fully open, allowing excessive cold air into the fridge.
- Control board: If the compressor never cycles off despite correct sensor and damper, the thermostat function on the PCB may be faulty and require replacement.
