Replace the sealing strip regularly. First, take out the magnetic stripe from the old door seal. Can be adsorbed on the box to avoid damage or breakage. Then, remove the old door sealing strip and replace it with a new one. Finally, insert the magnetic stripe just taken out into the new door seal.

Because the refrigerator door is opened and closed too many times, the refrigerator door seal is almost always under stress. If this state is maintained for a long time, the door seal is prone to aging and deformation, resulting in the refrigerator door not being closed tightly.

Proper maintenance. The refrigerator is not well maintained. In fact, refrigerators, like people, should be maintained frequently, sometimes improperly maintained or never maintained. It will make him sick. The refrigerator door won't close tightly.

Causes of frost:

Most water vapor comes from air. When people store food and open the refrigerator, indoor air exchanges freely with the gas in the refrigerator, and indoor humid air quietly enters the refrigerator.

Part of the water vapor comes from food stored in the refrigerator, such as vegetables and fruits washed in the crisper. Water in vegetables and other foods will evaporate and condense into frost when it is cold. Especially in summer, the indoor temperature is high and the humidity is high, and the temperature between room temperature and refrigerator is very different.

As soon as the refrigerator is opened, a stream of cold air flows out from it and indoor air enters the refrigerator. After a while, a layer of frost condensed on the refrigerator wall. It is also found that even if nothing is put in the refrigerator, a thick layer of frost will form in the refrigerator that is often opened, indicating that a large part of the water vapor in the refrigerator comes from the water vapor in the air.
