Possible Causes
Aging NTC sensors, Poor sensor placement or contact, Control board calibration drift, Airflow issues causing stratification
How to Fix / Troubleshooting
Safety: Unplug the refrigerator before accessing sensors or control boards.
Steps:
- 1. Verify with a reliable thermometer: Place a thermometer in water in the refrigerator and compare to the display after several hours.
- 2. Check sensor placement: Ensure sensors are properly clipped to their mounting points (evaporator, wall) and not hanging loose.
- 3. Replace suspect sensors: If readings are consistently off, replace the refrigerator compartment NTC sensor or freezer NTC sensor as appropriate.
- 4. Airflow: Avoid blocking vents with food, which can cause localized hot or cold spots.
Note: Minor differences (1–2°C) are normal; larger discrepancies indicate a sensor or control issue.
