Possible Causes

Aging NTC sensors, Poor sensor placement or contact, Firmware calibration offset, Airflow issues causing stratification

How to Fix / Troubleshooting

Safety: Unplug the refrigerator before accessing sensors or control boards.

Steps to correct temperature readings:

  • Verify with a reliable thermometer: Place a thermometer in water in the fridge and in the freezer to get accurate readings.
  • Check sensor placement: Ensure sensors are properly clipped and not touching warm lights or cold evaporator surfaces unless designed to.
  • Replace drifting sensors: If readings are consistently off and sensors test out of spec, replace the affected NTC sensors.
  • Control calibration: Some Vestfrost models allow minor temperature offset adjustments via the menu; consult the user manual.

Note: Allow at least 24 hours after any change for temperatures to stabilize before rechecking.
