Thank you for the question. It is not unusual for the digital temperature on the display to vary by up to 4 degrees compared to the actual temperature in the refrigerator or freezer, and it is very difficult to get an accurate temperature reading inside the compartments because:
- Hot air rises, and cold air falls. This can effect the shelf temperatures.
- Opening the door to read the thermometer allows cold air to escape, and warm air to enter causing an inaccurate temperature reading.
- Refrigeration thermometers are calibrated differently than regular household thermometers.
That said, if your RSG257AARS is varying by as much as 10 degrees, it may require service. To initiate service through Samsung, please submit an online service request through the link below, or call 800-SAMSUNG to speak with an agent who will be happy to assist you.
