1. Deicing with hot water: first cut off the power supply, then open the refrigerator, put a bowl of boiling water in the refrigerator, and wipe the ice with a dry towel after the ice falls off. If the ice does not fall off, you can gently break it with your hands to see if the ice is loose. 2. De-icing with a hair dryer: Set the hair dryer to the lowest level of hot air at a distance of more than 50 cm from the refrigeration pipe, and slowly blow against the ice. Be careful not to turn it to the maximum, otherwise it will easily damage the instrument parts in the refrigerator. After the ice is loose, gently break it with your hands.

/The reasons for this situation are:

1, the refrigerator has been opened and closed too many times. If we switch the refrigerator on and off many times in summer, hot air will enter the refrigerator and combine with the cold air in the refrigerator to form water vapor, which will freeze the refrigerator.

2. The water contained in vegetables will evaporate. As we all know, the water content in vegetables is very high. If the vegetables are not wrapped in fresh-keeping bags or insurance films when they are put into the refrigerator, the water vapor in the vegetables will evaporate and combine with the cold air in the refrigerator to produce ice cubes.

3. The water in the leftovers will evaporate. If the leftovers that are not completely cooled are directly stored in the refrigerator, the water vapor in the leftovers will rise and condense in the refrigerator and hang on the surface of the refrigerator, causing the refrigerator to freeze.

The exhaust pipe of refrigerator is broken. If the exhaust pipe of the refrigerator is damaged, the water vapor in the refrigerator can't be discharged in time, and the long-term steam accumulation is likely to cause the refrigerator to freeze.
