One corner of the freezer door is frozen.

1. It may be because hot food is placed in the corner of the freezer near the door. When hot objects enter the freezer, water vapor will condense into ice. 2. There may be cases where the refrigerator door is forgotten to close or the refrigerator door seal is not tight, or it may be that the outside air enters and condenses into ice due to frequent opening and closing of the freezer. It is also possible that the drain pipe is blocked, which causes more water in the refrigerator to freeze. Suggested measures: 1. In the process of using the refrigerator, it is necessary to clean the refrigerator regularly, and it is generally recommended to clean it once every six months. The food in the refrigerator will have a certain taste. Cleaning the refrigerator can ensure the safety and cleanliness of the refrigerator when storing food, and can also achieve the purpose of emitting odor. 2. Check the drain hole of the refrigerator regularly to ensure that the drain hole of the refrigerator is not blocked. You can also regularly check whether the refrigerator sealing strip is damaged or not tightly sealed, and replace it in time if necessary. Pay attention to close the door in time when using the refrigerator. If you forget to close the door or open and close the door frequently, it will reduce the service life of the refrigerator and increase the power consumption. 4. Ice cubes can't be removed with sharp objects, which may easily lead to the damage of the insulation layer inside the refrigerator. It is recommended to open it naturally or apply it with a hot towel, and then clean up the accumulated water.
