Causes and solutions of the refrigerator door not closing tightly;

First, the door seal is aging, because the refrigerator door is opened and closed many times, which makes the refrigerator door seal almost always in a state of stress. If this state is maintained for a long time, the door seal is easy to age and deform, resulting in the refrigerator door not being closed tightly.

Secondly, the suction of refrigerator door is not big enough. At present, most refrigerators on the market adopt drawer design, which solves the problem of opening and closing doors for children. However, once this technology is not too hard, it will easily lead to the loosening of the refrigerator door, which will make the refrigerator door very difficult to tighten.

Third, the refrigerator is not properly maintained. In fact, refrigerators, like us, should always be properly maintained. If it is not properly maintained for a period of time, it will make it sick and the refrigerator door will not close tightly.

Fourth, it is very important to clean the refrigerator correctly. For the treatment of the refrigerator, not only the inside of the refrigerator should be treated, but also the outside of the refrigerator should be cleaned frequently. Otherwise, once too many stains are deposited on the outside of the refrigerator, the refrigerator door will not be closed tightly, and the door seal should be cleaned regularly and correctly.
