1. First, check whether the normal closing of the door is affected by the high accumulation of goods. If there is such a phenomenon, it is necessary to adjust the placement of goods or redistribute space.

2. Secondly, check whether the door hinges and locks of the cold storage are stuck or damaged, and the damaged parts need to be repaired or replaced in time.

3. Then check whether the track of the refrigerator door is blocked by foreign objects, which causes the door not to close normally. If there are foreign objects, they need to be cleaned up in time.

4. Finally, check whether the sensor in the cold storage works normally. Sensor failure caused the door not to sense correctly and stop running. If there is any problem, please replace the sensor.
