What to do when the ice on the back of the refrigerator

One of the most common problems is that it intends to ice on the back of the refrigerator. "Indesit", "Atlant", LG - all models are subject to this malfunction. More often it occurs in refrigerators with a drip defrosting system. It is known that any malfunction in the unit affects its operation and introduces violations into the usual mode of freezing products. If they are in the snow and ice, then they themselves are more likely to turn into ice. After defrosting, such products will look, to put it mildly, unattractive. In addition, the snow may begin to melt, and the refrigerator because of this leak. If the ice on the back of the refrigerator intends, it does not need to be beaten. This will not solve the problem if the ice is formed due to the failure of any node. After a while, everything will happen again. So, what if the ice inside the refrigerator on the back wall?

First of all, it is necessary to identify the reason for this.

Reasons for intent when the refrigerator is working

1). In very warm weather, the cooling is adjusted to the highest level.

First you need to check if such an error is made. Often people think that the hotter in the room, the colder it should be inside the camera. But the temperatures outside and inside each other are not connected. Therefore, even in summer it is not necessary to include maximum freezing, since this will only increase the load on the motor.

2). A thin layer of frost appears and melts again.

If a small layer of frost forms on the wall, then it appears, then it wakes, there is no reason for panic. If the refrigerator has a drop defrost, then this phenomenon is quite normal.

3). Violated the rules of operation.

What ice targets at the rear of the refrigerator can occur due to improper compliance with the operating rules of the unit. In order to avoid frost, you do not need to put products inside the refrigerator that have not cooled down to room temperature. Upon evaporation, they condense. If the refrigerator is operating normally, then during the operation of the motor this condensate freezes, and then, when the compressor is turned off, thaws and water drains into a special container. But if the moisture that condenses is too large, the unit simply does not have time to thaw, and the ice on the rear wall of the refrigerator is intruding.

In other cases, probably, there is some kind of breakdown and repair is needed.

Frequent breakage of the refrigerator, leading to the formation of ice

Why does ice make ice on the back of the refrigerator? There are a number of frequent malfunctions that are characteristic of refrigerators with a drop defrost system. Further, these signs will be considered, as well as the possible causes of the malfunction.

Breakage of thermostat or temperature sensor

A sign of this is that the camera is too much frozen. This often turns on the motor, and rest breaks become very short. At the same time, the ice on the rear wall of the refrigerator intends evenly. In models with electromechanical control, the thermostat that measures the temperature of the evaporator fails. If the refrigerator has electronic control, then the problems with such symptoms are associated with an air temperature sensor that measures the temperature in the cold room itself. If this element fails, it erroneously gives a signal saying that the camera is not sufficiently cold, and forces the motor to run more often in order to reduce it even more. At the same time, the rear wall of the refrigerator does not have time to thaw, and ice appears on it. The solution is to replace the thermal sensor with a working one.

Freon leak

It happens that the refrigerator motor starts to work without stopping. The ice builds up unevenly and is most often formed in the corner of the chamber. If the defrost is performed, the refrigerator completely stops freezing. Such signs indicate a leak of freon. Most often this happens in the places of factory connections or in a "crying" evaporator, if it is affected by corrosion. With a leak, the motor runs constantly, as if compensating for the lack of cold. Such leaks must be eliminated, and the system must be refilled with a refrigerant. If there is a leak in the evaporator, it must be replaced.

Litter in the capillary pipeline

Symptoms of such a malfunction are poor cooling and non-stop operation of the motor. The refrigerator Atlant is subject to this problem. Ice freezes on the back wall with this problem very much. The compressor becomes hot. Because of the clog, Freon circulation is disturbed. And the reason is the condensed oil, which together with the refrigerant is present in the system. To solve the problem, you need to clean the system and restart it. Also, you need to check the oil and, if necessary, replace it.

Wear of rubber door seal

Inside the refrigerator gets warm air, and the motor starts to work, without turning off to reduce the elevated temperature. Because of this, the evaporator does not have time to thaw, and ice forms on the rear wall. Replacing the rubber band with a new one will solve the problem

Thus, if the refrigerator first frosted inside, it is recommended that it first be thawed. Probably, after that the problem disappears. If the ice builds up again, you should contact the service center for qualitative diagnosis and repair.
