Why the back wall of the refrigerator freezes up is a fairly common occurrence. Sometimes this happens due to a malfunction of the device, but in half of the cases it is caused by the carelessness of the owners. Calling the master or contacting the workshop is required only in those situations when it is not possible to fix the problem on your own. Therefore, consider the typical factors that create this problem.
Today, most of the modern models popular in our market by manufacturers (Ariston, Atlant, Bosch, Electrolux, Indesit, LG, Snaige, Stinol, Nord, etc.) are equipped with a No Frost cooling system. In them, the fan drives dry air through the compartments, preventing the formation of frost. If the ice on the rear wall of the refrigerating chamber still begins to grow, a complete inspection of the entire unit should be carried out and a further decision should be made.

How the refrigerator works
The study of the operation of the device will help to answer the question of why ice freezes in the refrigerator. The refrigeration equipment operates due to the freon circulating in its system. The compressor pumps gas (freon) into the condenser, where high pressure turns it into a liquid state. As it moves through the evaporator, the refrigerant is converted back to gas and returned to the compressor. The process of such circulation in a working device is continuous and allows the refrigerator to work without interruptions.
There are only a few varieties of models:
- contain one or two compressors;
- have one or two-circuit refrigerant circulation path;
- use static or dynamic (forced) cooling.
A good selection of models is provided by Atlant, Ariston, Samsung.
Reasons for the freezing of the snow "coat" on the back of the refrigerator
If snow and ice have appeared on the back of the refrigerator, then this may be preceded by several factors:
- The temperature regime of the refrigerator is violated. This happens when the rules for operating the refrigerator are not followed: food is put into it with a temperature higher than room temperature. The defrost sensors start to malfunction and ice builds up. To avoid this phenomenon, do not put hot food and dishes inside.
- The sealing rubber on the refrigerator door is worn out. In this case, ice and snow cover not only the back, but also the side walls of the refrigerator. Restoring the temperature balance will only help to replace the refrigerator seal. Here you can also do it yourself replace the sealing rubber on the refrigerator, the more you can purchase the necessary material in specialized retail outlets or on the market.
- Freezer overloaded. By hammering its internal space to the eyeballs, you contribute to the forced operation of the compressor, and its constant overloads can result in expensive repairs. Ice also builds up on the back of the refrigerator.
Complex malfunctions
Having excluded all the visible reasons due to which the back wall of the refrigerator is covered with snow, you have not yet determined why the refrigerator is very freezing, you cannot do without repairs. Having found out the reason for the appearance of ice on the back wall of the refrigerator, you can try to eliminate it on your own, although it will not be so easy, or you can resort to the help of a specialist.
There may be several factors leading to the appearance of ice in the refrigerator:
- failure of the thermal relay;
- defrost sensor malfunction;
- the appearance of a refrigerant leak.
To repair or replace these units, only a special tool will not be enough. You will need to have the necessary knowledge and practical experience. In order not to aggravate the situation, it is better to turn to professionals. The service staff will not only eliminate the malfunctions that have arisen, but will also conduct the necessary consultations on the further operation of the product so that it will serve you for a long time and faithfully.
