Common reasons: 1, the air humidity in the freezer is relatively high, and the evaporator temperature in the refrigerator is relatively low, so the temperature can be adjusted. 2. The drain hole of refrigerator is blocked, and it should be dredged in the right way. 3. The water vapor in the air condenses due to the damage of the refrigerator sealing strip, which can be solved by replacing the new sealing strip. Solution: 1 Can be solved by natural melting. If the ice layer in the refrigerator is thick, you can unplug the power cord of the refrigerator, then open the refrigerator door and take out the food inside, so that the ice in the freezer can naturally melt under natural conditions. 2. It can be solved by dredging the drainage pipe and melting naturally. When the refrigerator is in use, the drain hole in the freezer is blocked, which easily leads to poor drainage, so too much water will freeze. We should find out first at this time. If it is, it is necessary to clear the drain, then unplug the refrigerator and open the door to melt naturally. If the ice in the refrigerator is thick, you can handle it yourself, but if it is not solved well, you need to find professional maintenance personnel, which can avoid many problems. If you have no experience, it will directly affect the refrigeration effect of the refrigerator. The correct treatment method will improve the performance of the product, and you need to have certain operating conditions during the treatment.
