One of the most common problems is that ice freezes on the back of the refrigerator. Indesit, Atlant, LG - all models are susceptible to this malfunction. More often it is found in refrigerators with a drip defrosting system. It is known that any malfunction in the unit affects its operation and introduces violations in the usual mode of freezing products. If they are in the midst of snow and ice, then they themselves are very likely to turn into ice. After defrosting, such products will look, to put it mildly, unattractive. In addition, frozen snow may begin to melt, and the refrigerator will leak due to this. If ice freezes on the back of the refrigerator, it does not need to be beaten off. This will not solve the problem if ice is formed due to the breakdown of a node. After some time, everything will happen again. So what to do if ice freezes inside the refrigerator on the back wall?
First of all, it is necessary to identify the reason for this.
Causes of freezing when the refrigerator is in good condition
1). In very warm weather, cooling is adjusted to the highest level.
First you need to check if such an error has been made. Often people think that the hotter the room, the colder it should be inside the cell. But the temperatures outside and inside are not connected with each other. Therefore, even in the summer, you should not include maximum freezing, as this will only increase the load on the motor.
2). A thin layer of hoarfrost appears and melts again.
If a small layer of hoarfrost forms on the wall, which then appears, then thaws, there is no reason to panic. If the refrigerator has a drip defrost, then this phenomenon is quite normal.
3). Violated operating rules.
What freezes ice on the back of the refrigerator may occur due to improper compliance with the operating rules of the unit. In order to avoid frost, you do not need to put foods that have not cooled to room temperature inside the refrigerator. Upon evaporation, they condense. If the refrigerator is operating normally, this condensate freezes while the engine is running, and then it thaws when the compressor is turned off and water flows into a special container. But if the moisture that condenses is too large, the unit simply does not have time to thaw out, and ice freezes on the back of the refrigerator.
In other cases, there is probably some kind of breakdown and need repair.
Frequent damage to the refrigerator leading to ice formation
Why does ice freeze on the back of the refrigerator? There are a number of common faults that are characteristic of refrigerators with a drip defrost system. Next, these symptoms will be considered, as well as the possible causes of the malfunction.
Damage to the thermostat or temperature sensor
A sign of this is that the camera is freezing too much. In this case, the motor often turns on, and rest breaks become very short. In this case, the ice on the rear wall of the refrigerator freezes evenly. On models with electromechanical control, a thermostat that measures the temperature of the evaporator fails. If the refrigerator is electronically controlled, then problems with such symptoms are associated with an air temperature sensor that measures the temperature in the refrigerator itself. If this element fails, it erroneously gives a signal saying that the temperature in the chamber is not low enough and forces the motor to work more often in order to reduce it even more. At the same time, the back wall of the refrigerator does not have time to thaw, and ice appears on it. The solution is to replace the temperature sensor with a working one.
Freon leak
It so happens that the refrigerator motor starts to work non-stop. The ice builds up unevenly and most often forms in the corner of the camera. If you defrost, the refrigerator will completely stop freezing. Such signs indicate a leak of freon. Most often this happens at the factory connection points or in the “crying” evaporator if it is corroded. In the event of a leak, the motor runs continuously, as if compensating for the lack of cold. Such leaks must be repaired and the system recharged with refrigerant. If there is a leak in the evaporator, then it must be replaced.
Capillary blockage
Symptoms of this malfunction are poor cooling and non-stop operation of the motor. The Atlant refrigerator is subject to this problem. The ice on the back wall freezes with this problem very much. The compressor is getting hot. Because of the blockage, the circulation of freon is disturbed. And the reason is the thickened oil, which, together with the refrigerant, is present in the system. To troubleshoot, you need to clean the system and refill. You also need to check the oil and replace it if necessary.
Worn rubber door seal
Warm air enters the refrigerator 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 back wall. Replacing the gum with a new one will solve the problem
Thus, if the refrigerator is icy inside for the first time, it is recommended to first defrost it. Perhaps after this the problem will disappear. If the ice builds up again, you must contact the service center for a quality diagnosis and repair.
