The refrigerator always freezes in the cold storage. What could be the cause?

There are many reasons why the freezer is always frozen. First of all, if your food is put in the refrigerator before being measured, it will produce steam, which is easy to freeze at this time. There is too much water in the refrigerator, so the water evaporates easily, and then it will freeze. If you open and close the refrigerator frequently in your life, it will lead to hot air and then enter the refrigerator. After encountering cold air, it is easy to produce steam to freeze. So if your refrigerator is frozen now, the first thing to do is to cut off the power supply, then take out all the food in the refrigerator, and then clean the refrigerator before using it. In order to prevent the refrigerator from freezing, the first thing to pay attention to is not to open and close the refrigerator frequently, and it must be remembered that food can only be put into the refrigerator after measuring the physical quantity, because only in this way can the water vapor be reduced. Usually, after washing the dishes we eat, we drain the water outside and put it in the refrigerator, which can reduce the evaporation of water and prevent the refrigerator from freezing. When we store food in the refrigerator, we either put it in a sealed box or in a sealed bag. This can not only lock the moisture in the food in the refrigerator, prevent water loss, keep the food fresh, but also reduce the freezing of the refrigerator. There is another way to prevent the freezer from freezing, that is, after cleaning the refrigerator, we can brush a thin layer of cooking oil on the inner wall of the refrigerator, because this can prevent the freezer from freezing, and then even if it freezes, it is easy to clean it, which is also a very good way to protect the refrigerator. Therefore, the freezing of the refrigerator freezer is the above reason. If these reasons are avoided, the situation of icing will be reduced.
