Why does ice freeze on the back wall of the refrigerator?: causes of failure

Why the back wall of the refrigerator freezes is a fairly common phenomenon. Sometimes this happens due to a malfunction of the device, but in half of the cases it is caused by the safety of the owners. Calling the master or contacting the workshop is necessary only in those situations, when it is not possible to eliminate the problem by oneself. Therefore, let's consider typical factors, that create this problem.

Today, most modern models, manufacturers popular in our market (Ariston, Atlant, Bosch, Electrolux, Indesit, LG, In the snow, Stinol, Nord, etc.) They are equipped with a No Frost cooling system. They have a fan that blows dry air through the compartments, which prevents the formation of frost. If the ice on the back wall of the refrigerator still began to grow, a full inspection of the entire unit should be conducted and a further decision made.

The principle of operation of the refrigerator

Answer the question, why is there ice in the refrigerator?, learning how the device works will help. Refrigeration equipment works due to the freon circulating in its system. The compressor pumps gas (freon) in a condenser, where high pressure turns it into a liquid state. When moving along the evaporator, the reverse conversion of the refrigerant into gas occurs, 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 one, or a two-circuit coolant circulation path;
• use static or dynamic (forced) cooling.

Atlant provides a good selection of models, Ariston, Samsung.
