Possible Causes
Thermistor out of calibration, Stuck relay on main control board, Damaged thermistor wiring, Air damper stuck open (fresh food too cold)
How to Fix / Troubleshooting
Safety First: Disconnect power before accessing sensors, dampers, or control boards.
- 1. Verify actual temperature: Place an appliance thermometer in the compartment to confirm if it is truly too cold.
- 2. Inspect thermistor: Locate the compartment thermistor and check for secure mounting and connection. Replace if cracked or loose.
- 3. Check air damper (fresh food): If the refrigerator section is freezing food, inspect the air damper between freezer and fresh food. If stuck open, replace the damper assembly.
- 4. Control board: If temperatures are normal but LO persists, the main control may be misreading the sensor and could require replacement.
