Ice on the refrigerator wall cause

Ice in the refrigerator Atlant or any other cooling appliance can appear due to the loss of refrigerant or damage to some parts of the system.

Wear of the sealant

The part is designed to keep the space inside the refrigerator airtight. The material loses its properties over time. Damage to the sealing rubber may occur if the appliance is used improperly. Temperature in the chamber rises and causes the rear wall to freeze. The compressor tries to compensate for the lack of cooling by running continuously. Evaporator has no time to remove condensate. The ice builds up evenly.

It is possible to find out the defect on your own. To do this, a sheet of paper is clamped when the door is closed. After that, try to remove the object. If paper pulls out easily, gasket must be replaced.

Capillary tube is clogged

If the walls of the freezer compartment of the refrigerator are covered with ice because of clogged pipes of the cooling system, the following accompanying signs occur:

  • Compressor overheating;
  • Continuous operation of the motor;
  • Temperature rise in the main compartment;
  • Defrosting of foods placed in the freezer.

Capillary openings get clogged by the particles of machine oil that get heated during the circulation of freon. In this case, there is uneven distribution of the refrigerant, which causes ice to freeze on the rear wall of the refrigerator. The following actions help to eliminate the problem:

Freon leakage

If the quantity of refrigerant is reduced, ice freezes on the rear wall. snow is found in the corners. Unit stops cooling completely after defrosting. Causes of freon loss include:

  • Damage to the capillary system tubes that occurs when the refrigeration unit is not properly operated;
  • Corrosion of some parts of the system (the defect is more typical for drip refrigerators);
  • Cooling system tubes clogging.

If the Indesit No Frost freezes in the freezer and the engine starts to work continuously, it is necessary to look for the reason in the Freon leak. After a complete loss of the refrigerant the compressor stops and does not start. In this case the refrigerant needs to be replaced or topped up.

Thermostat breakage

If the walls of the freezer compartment are covered with ice, but the refrigerator is working and will not shut down, it is necessary to check the functionality of the thermostat. In this case the freezing becomes irregular. In devices with mechanical control relay located in the evaporator malfunctions. In the electronic systems the air duct is responsible for regulating the temperature. Defective part gives the compressor a signal to increase the temperature in the chamber. Motor starts to function without shutting down. The thermostat in this case should be replaced.

The insulation is frozen

In this case, the formation of ice crust covers only the damaged area. The failed section of insulation is removed and replaced with a new one. Repair is not cheap, if appliance is used for a long time you should think about buying another one.

Magnetic valve failure

The following signs help detect the malfunction:

Magnetic valve operates in 2 modes, which include alternate and simultaneous cooling of compartments. If there are voltage fluctuations, the part starts to work to lower the temperature in both compartments. This causes products to freeze and ice to build up on the surfaces. Temperature in freezer constantly rises.

Symptoms: compressor works too intensively, almost without pauses, refrigerator compartment overfreezes, on the back wall. uniform snow cover.

If the thermostat (or temperature sensor or air sensor) is broken, the control board receives incorrect information about the temperature in the chamber, and the control module gives wrong commands to the compressor, which toils tirelessly and freezes too hard.

To check that it is the sensor that is guilty, you can temporarily disconnect it, and connect the contacts directly: if the compressor began to work quieter, then the sensor is defective and it is better to replace it. But we still advise you to contact an expert, because the installation of the wrong sensor or its inaccurate connection can disable a much more expensive unit: a control board or a compressor.

Ice on the back of the refrigerator: what to do?

Repair

Having a refrigerator is a must for comfortable living. If it fails, it is a disaster of no small magnitude for any single family. Therefore, it is important to ensure that the equipment is in good working order. If the refrigerator ice freezes on the back wall. this is an occasion to identify the reason why it happens.

The presence of frost or ice on the rear wall can indicate many things, from improper use to a malfunction of the unit. You should not ignore such a signal, otherwise you can say goodbye to the island of cold in the kitchen.

The problem of ice formation on the walls of the chamber is encountered more often by owners of refrigerators with the drip defrost system, less often with the No Frost system. It is necessary to understand that occasional occurrence of thin layer of frost that melts quickly and drains into the drainage hole is a norm. But the increase in the thickness of the coat, the spread of the snow coating on the adjacent walls, freezing of food indicates a serious malfunction. Let’s consider the most common ones.

Refrigerant leakage

Freon circulating through the closed pipe provides the necessary temperature inside the refrigerator. In the case of natural wear and tear or mechanical damage of the gas pipeline, corrosion of the metal components of the system, or defects of the factory connections, the refrigerant leaks. Signs of failure:

Important! The place of freon leakage can be identified by a frost stain on the walls of the chamber or cooling elements.

Problems with the door

Leakage in the equipment is caused by the door seal being worn, the door not being adjusted at the proper height or an obstruction from inside the oven (e.g. protruding container). The signal for action will be:

  • The operation of the motor with rare pauses;
  • Uniform accumulation of snow cover all over the back of the refrigerator;
  • Audible sensor message about the door not being closed.

Help! In older models, the sensor is not provided, the only way to ascertain the malfunction is visually.

Other malfunctions

Information about the temperature in the chamber is recorded and transmitted to “headquarters” by the temperature sensor. Its breakage will cause a chain reaction: the unreliable information will force the compressor to work in the intensified mode, cooling the chamber and causing formation of ice and over-freezing of products. Clogging of cooling system tubes by foreign particles or products of oil waste products will not allow the freon to move evenly and fully perform its function: this will result in freezing of ice on the rear wall and overheating of the compressor. A clogged drainage system will cause water to form under the vegetable drawer and ice to form on the interior of the compartment and drain inlet.

Warning! To remove the “clot”, it is necessary to defrost the refrigerator completely and blow out the drainage system with a rubber blower.

Breaking the heat-insulating layer of the appliance causes condensation which can freeze through and form a thick crust of ice and snow in a certain area of the cavity. In single-compressor models it can happen the breakage of the magnetic valve that regulates the freon supply in the given contour: freezing or refrigerating compartment. “The symptoms of the disease are the evaporator temperature drop, the increased motor operation and the abundant freezing of the ice crust.

Important! Valve failure leads to rapid compressor wear and tear. To save its resource, disconnect the equipment from the network and call the repairman.

Freezing ice and snow in the refrigerator

The build-up of a snow “coat” inside the refrigerator is one of the most common and unpleasant defects of the unit. Frost formation forces the fridge owner to defrost the fridge, and you have to admit that this is not the most interesting and time-consuming task. And meanwhile the food waits in the warmth to finish this procedure, which can have a bad effect on its quality.

If you noticed that you have to defrost your fridge too often, then it is time to think about whether or not your unit is in good working order. After all, frost build-up is not a malfunction per se, but a consequence of a malfunction of one of the device components. So, what should be done first of all?

First of all it is necessary to check if the fridge is out of order.

Why in refrigerators the ice forms on the back wall: what to do, how to get rid of ice

Ice is the formation of ice in layers on the surface of an object. Physical phenomenon occurs when water spills from an array or flows from above onto a stably frozen platform. Ice in the refrigerator is an indicator that the household appliance has a malfunction.

As the refrigerant gives off heat from the chambers of the refrigerating unit, water droplets form on the inner walls of the chambers. Refrigerators with drip defrosting function, such as Electrolux, Biryusa, Pozis, Atlant or Ariston, are prone to this. Contrary to the statements, this can happen even in Bosch, Nord, Stinol units with “No Frost” function.

Ice can freeze in the following situations:

  • Worn seal.
  • Freon leakage.
  • Temperature sensor is defective.
  • Hotter is put into the refrigerator, causing heat exchange to be disrupted.

If there are doubts concerning the elimination of malfunction by your own efforts, it is better to apply to a service center or a master.

What to do if there is ice on the rear wall of the refrigerating chamber?

Ice and snow on the back wall of the refrigerator compartment is one of the most common faults. It occurs more often in the units with a drip system of defrosting of the fridge compartment. As you know, any malfunction of refrigerator makes its changes in its operation and breaks the usual mode of food storage. So, the foods that are surrounded by ice and snow are most likely to turn into ice flakes by themselves and after defrosting they will get an unpleasant look. Besides, the frozen snow “coat” can begin to thaw and the refrigerator can leak.

Meanwhile defrosting or “beating up” the ice is not the solution if the ice has formed due to the malfunction of one of the units. Most likely, after some time the “coat” will build up again. So, what one should do if there is ice frozen on the back wall of the fridge?

First of all, it is worth determining the cause of this phenomenon and establish whether something is really broken in the refrigerator, because the back wall of the refrigerator could be covered with snow and for other reasons not related to the failure of the unit.

When ice and snow coat on the back wall of the refrigerator is the norm

If your fridge is sweating inside, then the frost is building up on the walls and the process is repeating itself, this is normal for appliances that have a drip defrost system. It is used in the refrigerators of most modern models. This is a simple and efficient defrosting method.

An evaporator is installed behind the back of the unit and a drain underneath. When the motor is running, ice forms. When the compressor is turned off, the frost melts and the water droplets drip down. Liquid flows through the drain into the special tray on the motor, where it evaporates.
