It so happens that inside, on the back of the Biryusa refrigerator, Indesit, Atlant, ice freezes. A similar problem worries users. After all, constant freezing of products negatively affects their safety. An ice ball can begin to thaw. Because of this, water accumulates under the drawers.
If such a phenomenon arose for the first time, you do not need to panic, but first start defrosting the Indesit refrigerator or any other model. Perhaps it has simply not been defrosted for a long time, and this will help. But if, almost immediately after defrosting, the fur coat has grown again, it is worth considering whether everything is in order with the cooling device.
No need to beat off or crack ice. So you can damage the nodes. This will not solve the problem, but it can lead to more serious and costly breakdowns.
When ice and a snow coat on the back of the refrigerator is normal
If there is an insignificant layer of frost on the back of the refrigerator, it melts, then forms again - this is normal. Do not worry. So the drip refrigerator works.
The following causes, which are not related to breakdowns, arise from improper use. And the first mistake that many users make is setting the maximum cooling mode in hot weather. The erroneous opinion is that the hotter it is outside, the higher the cooling temperature must be set in order to preserve the products. When you turn on severe freezing, the compressor is subjected to a large load.
It is forbidden to load unheated foods, pots, pans without a lid. It is advisable not to put a lot of open containers with soups, borscht, juices and other dishes containing a lot of yushki.
During the operation of the refrigeration circuit, part of the liquid evaporates and falls out in the form of droplets of moisture on the back wall. In normal operation, when everything is in order, the droplets freeze during the operation of the motor-compressor. When the motor is idle, hoarfrost melts and flows down the drain pipe. But the device can no longer cope with a lot of moisture, so the snow remains on the wall. Due to excess moisture, more and more ice will form.
If the recommendations are followed, the user does not load hot foods, covers the pots with lids, and the back wall is still covered with ice, most likely the problem is a malfunction. Specialist assistance will be required.
When a wizard call is needed
About what damage is accompanied by the formation of ice on the back wall, we will discuss below.
Wear rubber
The task of the rubber seal is to ensure the tightness of the chamber. Over time, the seal wears out. It may also be damaged if handled improperly. This leads to an increase in temperature inside the chamber.
The compressor, trying to make up for the lack of cooling, works almost without shutdowns. In this case, uniform freezing occurs on the surface of the back wall. Why is that? This happens for the reason that the crying evaporator, due to the constant operation of the compressor, does not have time to melt, as it should. To check a guess, it is not necessary to wait for the master. You can do it yourself.To do this, take a piece of paper and pinch it between the refrigerator door. After that, try to pull out the sheet. If this was done easily, then the sealing rubber must be changed.
Capillary line clogged
With this malfunction, not only a “fur coat” appears, but also the following additional symptoms: the compressor is hot and works without interruptions. At the same time, there is no coolness in the refrigerator compartment, temperature indicators do not meet the standards and significantly exceed those set by the user.
The hole in the capillary can be clogged with clots of engine oil, which heats up when the freon is working. Such blockages result in uneven refrigerant circulation. To fix the problem, you will need:
- system cleaning;
- refueling it with freon;
- oil check.
Refrigerant leak
If refrigerant leaks, the back wall will become uneven. Typically, ice forms in the corner. After that defrosting the refrigerator with this malfunction, he will stop cooling altogether.
The causes of gas bleeding are different - from factory defects to corrosion damage. The latter usually occurs with a crying vaporizer. At the same time, the refrigerator engine begins to "plow" intensively without shutting down. Thus, he is trying to make up for the lack of cooling capacity.
After freon completely disappears from the refrigerator, the compressor stops its work. To fix the problem, you will need to find, first of all, the place of damage, eliminate it. After that, you need to refill the system with freon.
Temperature sensor breakdown
A malfunction is indicated by a symptom such as frequent activation of the refrigerator motor. The rest cycle is shortened. The refrigerator freezes food, and freezing occurs evenly.
In the large mechanical appliances under consideration, these signs can indicate a breakdown of the capillary thermostat located in the evaporator. In electronic refrigerators, this job is done by the blower. It controls the temperature right in the compartment.
What causes freezing? Everything is simple. A faulty element falsely notifies the device that there is insufficient cold in the compartments. Trying to reduce the seemingly too high temperature, the motor works without turning off. The temperature sensor or thermostat must be replaced.
The insulation of the refrigerator is frozen
With this malfunction, ice in the form of a thick layer of ice or snow forms at the site of damage. The frozen insulation section is cut out and replaced with a new one. Pretty expensive service in repair shops.
Solenoid valve failure (in single compressor)
This malfunction can be suspected by the following symptoms:
- in the freezer, temperature readings are higher than those set by the user.
- ice appeared in the refrigerator compartment.
Technologically, there are 2 operating modes for this cooling switch between the refrigerator and the freezer: cooling chambers one by one, and then at the same time. Due to a power surge, the valve sticks on the cooling of 2 compartments, as a result of which the refrigerator freezes products, and cooling is insufficient for the freezer.
