Refrigerator displays temperature but actual temperature is significantly different from the set value

Safety first: Use a reliable fridge thermometer to verify temperatures.

• Measure correctly: Place a thermometer in a glass of water on the middle shelf and check after 12 hours for an accurate reading.
• Adjust settings: Change the set temperature one step at a time and recheck after several hours.
• Avoid frequent door openings: Repeated openings can cause temporary warm readings.
• Sensor replacement: If readings remain inaccurate despite adjustments, replace the relevant temperature sensor.
• Control board: Persistent calibration errors after sensor replacement may require control board replacement by a technician.
