What is the reason for the freezing of the fresh-keeping layer of refrigerator and how to solve it?

1, which may be due to improper daily use of the refrigerator and frequent opening and closing of the door, causing external water vapor to enter the fresh-keeping layer and freeze when it is cold. 2, the refrigerator has a long service life, the rubber strip is aging, and the seal is not tight, which leads to the entry of water vapor and the freezing. The thermostat of the refrigerator is broken, which causes the compressor to keep cooling, causing serious icing. 4. Put too much food or fruit with high water content. 5. The drain of the refrigerator is blocked, resulting in water not being discharged in time and forming ice. Suggested solution: 1. Use the refrigerator correctly and don't open and close the refrigerator door too often, especially when the weather is hottest in summer. 2. Contact the refrigerator maintenance personnel to replace the rubber strip of the refrigerator to ensure the best sealing effect of the refrigerator. 3. Check whether the thermostat of the refrigerator works normally. This operation needs to contact a professional home appliance maintenance master or refrigerator after-sales maintenance personnel. Individuals have no way to identify. If there is a problem, it can be replaced directly. If there are fruits and vegetables in the refrigerator, it's best to put them in a fresh-keeping box or wrap them with plastic wrap, so as to ensure freshness to the maximum extent and reduce power consumption. 5. Check whether the drain of the refrigerator is blocked. If it is blocked, dredge it in time to ensure that there is no water in the fresh-keeping layer, which effectively reduces the icing phenomenon.
