The LG Thermostat: a technical dossier
The thermostat (or temperature sensor in LG inverter models) tells the control board when to cool. A faulty reading causes the fridge to run non-stop, freeze food, or not cool at all.
- Fridge too cold or freezing food
- Fridge not cooling at all
- Temperature swings between cycles
- Error code for sensor fault
- Compressor never switches off
- Read the sensor resistance across temperature ranges
- Compare against LG spec values
- Test the main board sensor input
- Replace the temperature sensor or thermostat
- Calibrate and verify cycling
