Why does ice in the fridge freeze up on the back wall?

In the fridge freezes ice on the back wall. This phenomenon is familiar to many owners of similar devices for storing products. The new refrigerator works fine, but over time, frost appears on its walls, and then ice. The device stops working normally. What to do with it in this case: try to find the cause yourself or call specialists right away?

Why ice forms

Why freezes the back wall of the refrigerator? The reasons are different. For their exact definition, you need to know exactly where frost is growing. Only after determining the exact cause of the malfunction, can we proceed to refrigerator repair. Frozen appears for the following reasons:

• defrost sensor stopped working;
• worn out the refrigerator seal;
• disturbed normal operation of the compressor.

If the defrost sensor stops working completely or partially, snow or ice forms on the back of the unit. When the sensor is working properly, the frost can hold up to 15 minutes. In the next 30 minutes it melts. It happens to single compressor refrigerator. In a double-frost on the wall lasts up to 35 minutes. If you put hot dishes in the appliance, this will also affect the operation of the refrigerator. A plate with freshly baked pies or hot soup that is close to the sensor can simply disable it. When cooling down, the products will leave droplets of moisture on the walls, which turn into ice crystals.

If the refrigerator freezes ice on the side walls, this means wear of the seals. Replacement of sealing rubber happens in many ways. Often it is installed in special slots. Then you just need to remove the old seal and insert a new sealing tape into the groove. It does not need any fasteners. In other cases, it may stick to the door or fasten to it at several points.

Ice on the back wall and in case of malfunction compressor. This can happen if refrigerant leaks from the system.The compressor starts to work almost without rest. His constant work causes an increase in temperature in the chamber, which leads to the appearance of snow and ice on the walls.

The above reasons that the wall is covered with snow and ice are reasons for inviting a specialist to eliminate them. From such cases saves buying new equipment. It is usually equipped with a system. No frost. These are Ariston, Bosch, LG, Stinol, Atlas, Electrolux, Indesit, Nord, Snaige and some other brands. In their cells, the fan drives dry air, which prevents the formation of a snow crust on the walls. But not everyone has this opportunity. Then defrost the refrigerator have to do it yourself.

When replacing the sensor you need to buy it from a reliable seller. It is better to do this in the service center. Many of the details on the appearance seem to be exactly the same. Only some letters and numbers in their designation differ. But it is they who can completely destroy the refrigeration equipment.

Other causes of snow and ice

Why else on the back of the refrigerator appears snow coat? The reason may be:

• constant burning lamp lighting;
• loose fit of the door;
• the refrigerator is full of groceries;
• cold regulator is not in that position;
• there is freon leak (refrigerant);
• electromagnetic valve failure (for two-chamber refrigerators);
• clogged capillary tubes.

A burning camera light also affects the microclimate. The door may not fit tightly. It needs to be adjusted. With a large number of products in the refrigerator, the compressor is almost not disconnected from the network. Ice appears on the back wall. The position of the cold adjuster also matters. It is not recommended to turn it on to the maximum value, especially when the refrigerator is full. In case of refrigerant leakage, the call of the master is obligatory. Previously, to eliminate this cause, it was necessary to take the unit to a repair shop.

Today, masters can do all the work at home in an hour. They will find a leak, refuel the system, after which the refrigerator freezes again normally.

The two-chamber refrigeration unit has an electromagnetic valve. It automatically regulates the cooling of a particular chamber. Ice and snow on the back of the refrigerator may appear in the event that the cooling is only in the refrigerator.The freezer can also defrost. The cause of the appearance of ice may be clogged tubes on which the refrigerant moves. This reason can be removed only by a specialist.

Instead of a conclusion on the topic

Snow and ice on the back of the refrigerator is a frequent occurrence. It may be a sign of a malfunction of the apparatus or its individual mechanisms. It can be seals, tubes, regulators, relays, compressor.

To eliminate the causes you need to call on the master of the repair of refrigeration equipment.

He is able to locate the problem and eliminate it. Do not fully load the camera products. You can not put in a hot dish. These measures are known to everyone, but are far from being implemented by everyone. As a result, the compressor has to work almost without stopping. This leads to breakage and the need to replace parts.
