The reason may be that the refrigerator has just been put into use, so the sealing strip at the door of the refrigerator still has strong suction, so you can wait patiently for a while before trying to open it; The reason may be that in the process of starting refrigeration, the refrigerator is cold inside and hot outside, and the pressure inside and outside the refrigerator forms a certain difference, which makes the door cover of the refrigerator sucked tightly. Before balancing the pressure, we can observe whether there is a strong temperature difference and pressure difference. The reason may be that the sealing strip of the refrigerator door is too poor, which causes the outside air to enter and form frost.

In addition, it is possible to encounter the situation that the freezer door of the refrigerator is frozen by the inside of the refrigerator. If this happens, users are generally advised to unplug the refrigerator, wait patiently for about 10 hour, and then try to open the refrigerator door. At the same time, it should be noted that in order to prevent the cupboard door of the refrigerator from being frozen inside again, we should adjust the temperature of the refrigerator freezer to about third gear to avoid the temperature difference between the refrigerator freezer and the high temperature outside because it is too low. If it is found that the cupboard door of the refrigerator still cannot solve the problem of freezing, then the temperature control of the refrigerator is damaged and needs to be repaired and replaced in time.
