The Mijia Refrigerator Cross Door 502L is designed with a heat-dissipation system that releases heat through both sides of the refrigerator. Therefore, it is normal for the sides to feel warm during operation, and no special treatment is required. To ensure efficient performance, please leave enough space around the refrigerator and avoid placing objects too close, as this can block airflow and reduce cooling efficiency.
Additionally, the door frame of the refrigerator also functions as a condenser. This design prevents the door from freezing shut, ensuring smooth opening and closing in daily use. The warmth you feel around the frame is a normal phenomenon caused by this process. As long as ventilation is unobstructed, the heating does not indicate any malfunction and requires no repair.
