refrigerator Causes of snow coat on the back of the
refrigeratorSometimes this is 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 going to the workshop is required only in those situations when the problem cannot be fixed on its own. Therefore, we consider the typical factors that create this problem.
Today, most modern models, popular in our market of manufacturers( Ariston, Atlas, 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 back wall of the refrigerator still began to grow, you should conduct a full inspection of the entire unit and take a further decision.

The principle of operation of the refrigerator

To answer the question of why ice is frozen in the refrigerator, a study of the operation of the device will help. Refrigeration equipment works by freon circulating in its system. The compressor injects gas( freon) into the condenser, where high pressure turns it into a liquid-like state. When moving through the evaporator, the refrigerant turns back into gas, and it returns to the compressor. The process of such circulation in a working device is continuous and allows the refrigerator to work without failures.

There are only a few varieties of models:
- contain one or two compressors;
- have a single or dual circuit refrigerant circuit;
- use static or dynamic( forced) cooling.
A good selection of models provides Atlas, Ariston, Samsung.

Causes freezing of snow "fur coat" on the back of the refrigerator

If there is snow and frost on the back of the refrigerator, then several factors may precede this:
- The temperature of the refrigerator is disturbed. This happens when the rules for operating the refrigerator are not followed: food with a temperature above room temperature is placed in it. Defrost sensors start working incorrectly and frost appears. To avoid this phenomenon, do not put inside hot food and dishes.
- Worn rubber seals on the refrigerator door. In this case, the frost and snow cover not only the back, but also the side walls of the refrigerator. Restoring the temperature balance will only help the replacement of the refrigerator seal. Here you can also replace the sealing rubber on the refrigerator with your own resources, the more you can buy the necessary material in specialized outlets or on the market.
- Overloaded freezer. Scoring its internal space to the eyeballs, you contribute to the forced operation of the compressor, and its permanent overload can result in costly repairs. There is also ice freezing on the back of the refrigerator.
Complicated Malfunctions

Having found out the cause of ice on the back of the refrigerator, you can try to fix it on your own, although it will not be so easy, or you can resort to the help of a specialist.

There can be several factors leading to ice formation in the refrigerator:
- failure of the thermal relay;
- defrost sensor malfunction;
- refrigerant leakage appearance.
To repair or replace these components, it will not be enough just a special tool. You will need to have the necessary knowledge and practical work experience. In order not to aggravate the situation, refer better to the professionals. Service staff will not only eliminate the malfunctions that have occurred, but will also conduct necessary consultations on the further use of the product so that it will serve you for a long time and truly.
