Why is the temperature displayed on the Mijia Refrigerator Side-by-Side 621L different from the actual temperature?

The temperature displayed on the Mijia Refrigerator Side-by-Side 621L represents the set temperature, which can differ from the actual temperature inside the refrigerator.
The actual internal temperature can fluctuate due to factors such as door openings, food placement, ambient temperature, and cooling cycles. In addition, the refrigerator compressor does not operate continuously. It automatically starts and stops according to the cooling requirements to maintain the target temperature efficiently.
Therefore, some temperature fluctuations inside the refrigerator are normal, and the displayed temperature may not always match the temperature measured at a specific location inside the compartment. If cooling performance is otherwise normal and the refrigerator can maintain the set temperature over time, this difference generally does not indicate a malfunction.
