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.
