When you opened the refrigerator, did you see ice on the back wall? So, you are faced with the most common problem of refrigeration equipment - freezing. Usually it is typical for “crying” models with drip thawing of the main camera. The first unpleasant consequence is food spoilage. In addition, the snow or ice cover of the chamber will periodically thaw, which will create an additional problem with leaks.
If you notice ice on the wall, the cause should be found right away. Do not try to crack ice and defrost cameras continuously. This is not a solution, because frost and ice are symptoms of a serious malfunction. Therefore, having discovered ice on the back wall of the Atlant refrigerator (or another brand), you need to understand what contributed to this. Often snow is not a sign of breakage at all, but more on that below.
When the "coat" on the wall is not a breakdown
When ice freezes on the back wall (Stinol, Ariston, Nord and other brands), the reasons may be as follows:
- Wrong cooling mode. This is especially true for users who believe that in the heat you need to set the lowest temperature mode. It ends with a frozen wall. As for the freezing regimen, then on hot days it is worth giving up.
- A constant layer of frost forms and melts. This is also not a breakdown if the defrost is “drip” type. You can confidently use refrigeration equipment (hereinafter - XO).
- Improper operation. The ice on the back wall of Indesit, Samsung, Bosch (and other brands) can grow due to neglect of the manufacturer's recommendations. If you load shelves with unheated dishes without a lid or put a lot of open containers with liquid, the water will evaporate and collect in the form of drops on the back wall. When the cold circuit is operating, the drops will turn into ice, which will thaw when the heating starts. If the drainage hole is not clogged, the water will go into the drain without creating problems. And with a clogged drain pipe, the water will go under the drawers, creating additional difficulties. Due to the excess moisture in the ice chamber, each time there will be more.
When all of the above reasons are excluded, and the snow or ice still does not leave the compartment wall, then there is a breakdown. What malfunctions can cause freezing of the evaporator, you will learn further.
Snow on the back of the refrigerator: causes and signs of damage
In the table we have collected the most likely failures that can provoke freezing of the wall. If you have a “crying” vaporizer, these reasons will be relevant.
Sign | Why the problem appeared |
The refrigerator compartment freezes. The compressor practically does not turn off, and rests only a few minutes. The nature of the snow cover on the back wall is uniform. | Likely, temperature controller broke (the thermostat is typical only for models on the electromechanical type of control). The unit regulates and measures the temperature in the chamber. In the electronic model could break air temperature sensor, which monitors the cooling of the main camera. A faulty sensor reports incorrect signals to the control unit that there is too little cold. The compressor runs for a long time and almost does not stop, trying in vain to lower the temperature, which is already normal. Due to excess cold, snow grows on the back of the refrigerator. Replacement of faulty components is required - thermostat or sensor. |
The compressor is in continuous operation. Freezing is uneven, mainly in the corners of the chamber. Attempts to defrost the refrigerator end with his refusal to work. | Diagnostics should show freon leak. In most cases, refrigerant is allowed to pass through soldering spots. If the refrigerator is many years old, and it already has a rusty evaporator, freon can leak out from there. Due to a leak in the chambers, it is warming, so the motor runs non-stop to compensate for the loss of temperature. To eliminate the malfunction, refrigerant charge is required. If during diagnostics it is discovered that the leakage is the foam part of the evaporator, replacement of this part is required. |
The main chamber does not cool the products, the compressor works without pauses. A “fur coat” grew on the wall. The motor compressor is hot. | The capillary tube is clogged, due to which the uniform circulation of the refrigerant is disturbed. How is a “blood clot” formed in the pipeline? Usually these are clots of engine oil from a compressor, which is heated when Freon is heated. How to fix a failure? It is necessary to clean the system, charge it with refrigerant, check the oil, if necessary, add a new one. |
Freezing the wall is uniform. Compressor operation is constant. There are almost no shutdowns. | Inspect the gum seal on the refrigerator door - it may be worn or damaged. Warm air outside goes into the compartment. The compressor is trying to cool it to the desired parameters. There is no evaporator defrost (due to compressor operation without shutdown), therefore ice or snow appears on the wall. It is necessary to repair or replace the seal. |
The wall is overgrown with a block of ice or a lump of snow in a certain part. | It is worth checking the insulation of XO. If thermal insulation is broken (when getting wet from excessive formation of condensate droplets), it is necessary to replace it partially or completely. |
The main chamber freezes too much, the back wall is frozen, and the temperature in the freezer is high. | Damage to the solenoid valve. This part monitors the alternate cooling of each compartment. If the valve fails and “freezes” on cooling of both chambers at once, there is not enough cold for the freezer; the refrigerator compartment, on the contrary, is too cold. Replace valve. |
Important! In our review, we did not write about refrigerators No Frost, as these models are characterized by freezing not of the main compartment, but of the freezer. This is because there is no such part as an evaporator in the refrigerator. This item is one on both chambers, and is located in the freezer. That is why ice or a "fur coat" inside grows only in the lower chamber.
If the “fur coat” in your Indesit refrigerator (or any other) has appeared for the first time, you can take no active action. For starters, try defrosting XO. If the snow or ice does not return after the procedure, then there is no question of a serious breakdown. If the situation repeats, contact the wizard for diagnostics and further repairs.
