Why does the top of the refrigerator always freeze?

1. When the weather is hot, the refrigerator door is frequently opened and closed, resulting in a large temperature difference between the inside and outside of the refrigerator, and external humid air enters the refrigerator and freezes when it is cold.

2. Long-term aging of refrigerator sealing strip leads to lax sealing, and outside air enters the refrigerator and freezes when it is cold.

3. The thermostat gear of the refrigerator is set too low or the thermostat fails, which leads to the continuous refrigeration of the compressor, resulting in the temperature of the fresh-keeping layer being lower than the applicable temperature in the normal state of the fresh-keeping layer, resulting in icing.

It is also possible that the drain of the refrigerator is blocked, and the water can't be discharged, so it can only be left in the refrigerator. When the temperature of the fresh-keeping layer of the refrigerator is low, it will freeze.

Solution:

1. First take out all the food in the refrigerator and put it away, turn off the power of the refrigerator, then let the frozen ice melt naturally or shovel the ice manually, and then brush a layer of oil on the inner wall of the refrigerator after cleaning the ice, which can effectively prevent it from freezing again.

2. Adjust the thermostat of the refrigerator and raise the temperature or gear a little, so that the overall temperature of the fresh-keeping layer of the refrigerator will also rise, and it is not easy to freeze.

3, reduce the number of unnecessary refrigerator door switches in daily use and reduce the working time of the compressor.

4. Replace the sealing strip of the refrigerator.

The drain pipe of refrigerator is blocked.
