There are some “iron” and quite obvious rules: do not put hot drinks into the fridge, do not place open containers with liquids, do not leave the door open for a long time: please keep them in mind. Moisture that evaporates condenses on the walls and freezes, and if you put something hot near the sensitive defrost sensor, it can easily break down. You should not experiment on your fridge: it may offend and stop working.
It is possible that just in case you have set the temperature too low in the chamber and as a result the food there started to freeze and on the walls of the chamber. Frost formation. It is better not to do that as the fridge is designed for cooling even in conditions of quite high temperature outside: by insuring too much you will only increase the load on the compressor that, beside the inevitable additional electricity bill, will lead to the accelerated depreciation of the compressor.
The ice or water forms on the fridge rear wall why and what to do
It happens so that inside, on the back wall of the refrigerator Biryusa, Indesit, Atlant the ice is freezing. Such a problem worries users. Constant freezing of the food has a negative effect on its preservation. The ice lump can start to thaw. Because of it the water is accumulated under the drawers.
If such a phenomenon has occurred for the first time, it is not necessary to panic, and for a start to defrost the refrigerator Indesit or any other model. Maybe you just haven’t defrosted in a while, and this will help. But if almost immediately after defrosting the coat has built up again, you should wonder if everything is okay with the cooling unit.
There’s no need to chop or chip away the ice. You can damage components that way. It will not solve the problem, but it can lead to more serious and costly damage.
The problem of ice formation on the walls of the chamber is encountered more often by the owners of refrigerators with drip defrost system and more seldom with No Frost system. It should be understood that the occasional appearance of a thin layer of frost, which quickly melts and drains into the drainage hole is normal. But the increase of the coat thickness, the spread of the snow cover on the neighboring walls, the freezing of the foods indicate the serious defects. Let’s look at the most common ones.
Freon, circulating through a closed line, provides the desired 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, defects of the factory connections the refrigerant is leaking. Signs of failure:
Important! The location of a freon leak can be identified by a frost stain on the chamber walls or cooling elements.
Improper sealing of the equipment is caused by the door seal being worn, the door not being adjusted at the proper height or an obstruction from the inside of the room (e.g. protruding container). Signal to action will be:
- motor operation with infrequent pauses;
- Uniform growth of the snow coating on the whole back wall of the refrigerator;
- Door sensor beeps if door is not closed.
Reference! In old models there is no sensor; it is possible to check the defect only visually.
The temperature in the chamber is recorded and transmitted to the “headquarters” temperature sensor. Its failure will cause a chain reaction: unreliable information will force the compressor to work in intensified mode, cooling the chamber and causing the formation of ice and over-freezing of products. Obstruction of the cooling system tubes by foreign particles or products of used oil does not allow the freon to move evenly and fully perform its function: this results in freezing of the ice on the rear wall and overheating of the compressor. A clogged drainage system will cause water to form under the vegetable drawer, ice to form on the interior of the compartment and on the drain inlet.
Warning! To remove the “clot”, the refrigerator must be completely defrosted and the drainage system must be blown out with a rubber blower.
Damage to the unit’s thermal insulation layer causes condensate to form and freeze through, forming a thick crust of ice and snow in a particular area of the chamber. In single-compressor models it can be breakage of the magnetic valve that regulates freon supply for a given circuit: freezer or refrigeration compartment. “Symptoms of the disease” will be a decrease in the temperature of the evaporator, increased motor operation and abundant freezing of ice crust.
Important! Failure of the valve leads to rapid wear of the compressor. For preservation of its resource, unplug the equipment from the network and call the repairman.
Review of basic problems and tips for their elimination
If there is ice in the refrigerator, then before you grab your head and beat the alarm, check the position of the knob of the thermostat. Maybe you overheated it to the full maximum or to the super-freezing mode. If it is confirmed, then put the regulator in the position corresponding to the minimum or medium temperature of freezing. Observe for a couple of days how the refrigerator operates and whether the generation of excessive cold continues. If the position of the regulator is on minimum, but the refrigerator still “freezes to the soul”, it certainly indicates a technical problem. As a rule, they require a master from the service, because they cannot be repaired at home.
In the best case if you are lucky, the master will repair the defect at once in your presence. But, often, your refrigerator will have to be taken to a repair shop. However, there are certain malfunctions that you will be able to fix. The same concerns elementary rules of operation, which are recommended to be followed by the manufacturers of the refrigerating machinery.
Something that cannot be fixed yourself at home:
- Freon leakage. special equipment and skills are required, in this case it is possible to refill the freon at home with the participation of a service technician, who must, first of all, find and fix the crack through which the refrigerant has escaped
- Evaporator malfunction. can be repaired or replaced with a new one
- Faulty thermostat, air thermostat, heating element or solenoid valve. requires repair or replacement with a new one
- Compressor malfunction. repair or replacement. It is worth mentioning that compressor is almost the most expensive element of the refrigerator mechanics and its repair or replacement can cost one third or even half of the cost of the refrigerator. What to do in this case is up to you to decide. Sometimes it is simpler to buy a new fridge
What you can do on your own at home:
- Find the right place to install your refrigerator, away from heaters, stoves and direct sunlight
- Do not open the fridge unnecessarily and do not leave the doors open for a long time
- Defrost your fridge or freezer with a manual defrosting system and wash it regularly
- Adjusting the door to make sure that the refrigerator closes tightly
- The door gasket wear and tear can cause poor closing and warm air penetration and, as a result, freezing in the fridge compartment
Why the freezer freezes in the refrigerator No Frost: possible problems
Let us have a look at the possible malfunctions that result in freezing of the refrigerator.
The drain hole in the freezer is clogged
This problem is characterized by the accumulation of snow and ice on the bottom. When the “No Frost” system is operating normally, the chambers are cleaned from the ice at least once a day. This happens in the following way: to turn the ice into water, connect the heating element. The water formed drains through the drainage system. But if the drain hole is clogged, the water has nowhere to go. It stays under the boxes, freezing up in thick blocks of ice.
To fix the problem, you need to clean the drain. This can be done by using warm water and a medical pump or a hand pump. However, unlike the fridge compartment, in order to access the drainage hole in the freezing chamber, it is necessary to unscrew the back panel.
Defrost system malfunction
There are various components that can break: fuses, heaters, timers, etc. д. At the same time, if something has failed, defrost cycle will not start, the refrigerator ceases to be “No Frost”. It will be necessary to carry out a complete diagnosis of this system, to identify the fault and eliminate it. It is better to entrust this work to professionals.
Faulty temperature sensor
If this problem occurs, the walls will ice up evenly. If we are talking about two-compressor systems, only the freezer will freeze, if about single-compressor. the food in the refrigerator will also be frozen.
The purpose of the temperature sensor is to measure the temperature in the chambers. If this element fails, the refrigerator gets the wrong data. Thus, thinking that it is not cold enough in the chambers, the compressor works without stopping.
Wear of the rubber seal
The rubber band around the perimeter of the door deteriorates because of long use or because it is damaged. As a consequence, the tightness is lost and the heat enters the chambers.
The “growths” are irregular and located closer to the door. The temperature in the chambers is too high. On models with electronic display, corresponding error code may be displayed. Worn out seals need to be replaced.
Door not tightly sealed
Symptoms of malfunction are similar to those of a worn seal. The cause is the same: leaks in the chambers.
As you know, the door is mounted on hinges. If the hinges have sagged or become loose, the seals are compromised. Door needs to be adjusted.
Finding the place of the leak and charging of freon is a complicated process that is better to trust the professionals
If the Freon is leaking the refrigeration capacity drops. Compressor struggling to make up the deficiency, at first runs non-stop. The motor won’t start at all after the gas has completely evaporated. If you have a refrigerant leak, the ice is usually located in the evaporator area of the freezer.
Why is there ice on the back wall in the refrigerators: what to do, how to get rid of ice
Ice formed in layers on the surface of an object. The physical phenomenon occurs when there is a spout from the array or water coming in from above on a stably frozen platform. Ice in the refrigerator is an indicator that the household appliance has a malfunction.
Ice in the Atlant refrigerator or any other cooling appliance can appear due to loss of refrigerant or damage to some parts of the system.
Wear of the gasket
The part is designed to keep the space inside the refrigerator airtight. The material loses its qualities over time. Damage to the sealing rubber can be caused by improper use of the appliance. Temperature rises in the chamber causing the rear wall to freeze. The compressor tries to compensate for the lack of refrigeration by running continuously. Evaporator does not have time to eliminate condensation. Ice builds up evenly.
You can identify the malfunction on your own. For this purpose a sheet of paper is clamped when the door is closed. After that they try to take out the object. If the paper is easily removable, the gasket has to be replaced.
Capillary tube clogging
If the walls of the freezer compartment of the refrigerator are covered with ice due to clogged pipes of the cooling system, the following accompanying signs occur:
- Compressor overheating;
- Continuous motor operation;
- An increase in temperature in the main compartment;
- Defrosting the food placed in the freezer.
Capillary openings become clogged with particles of machine oil heated during freon circulation. In this case, unequal distribution of the refrigerant is observed, as a result of which ice freezes on the back wall of the refrigerator. The following actions help to eliminate the problem:
When the amount of refrigerant is reduced, ice freezes on the back wall in one place. snow is found in the corners. After defrosting, the unit stops cooling completely. Causes of loss of freon are:
- Damage to the capillary system tubes due to improper operation of the refrigeration system;
- Corrosion of some parts of the system (the malfunction is most characteristic of the drip refrigerators);
- Clogged pipes in the cooling system.

If Indesit No Frost freezes in the freezer and the engine starts to work continuously, it is necessary to look for the reason in freon leakage. After a complete loss of refrigerant, the compressor stops and will not start. In this case it is required to replace or refill the freon.
If the walls of the freezer are covered with ice, and the refrigerator works and does not turn off, it is necessary to check the functionality of the thermostat. The freezing in this case has an irregular character. In machines with mechanical control, the relay located in the evaporator malfunctions. In electronic systems, the air duct is responsible for temperature regulation. Defective part gives signal to compressor to increase temperature in the chamber. Motor starts to run without shutting down. The thermostat must be replaced in this case.
The insulation is frozen
In this case, the formation of ice crust covers only the damaged area. Failed section of insulation is removed and replaced with a new one. Repair is not cheap, if the device is used for a long time, it is worth thinking about buying another.
Magnetic valve failure
The following signs help to detect a malfunction:
The solenoid valve operates in 2 modes, which include alternating and simultaneous cooling of the compartments. If there are voltage fluctuations, the part starts to work to lower the temperature in both compartments. This causes food to freeze and ice to build up on the surfaces. The temperature in the freezer is constantly rising.
Probable breakdowns: what to do
In the fridge, on the back wall, the ice is freezing and there is a reasonable question what to do. It is better to fix the failure immediately, before there are serious problems.
In normal mode the refrigerant circulates correctly. But the tubes can rust, crack or burst and the freon can escape. In this case the refrigerant drips on the case and snow or frost may appear on this part of the surface. Ice can also appear in the corners on the back walls of the camera.
It is better to find the leak before the refrigerator stops functioning. There’s nothing you can do on your own. Only an expert can braze or replace the tubes and top up the freon.
Wear on the gasket
This is the most common reason for ice to freeze on the back wall. The sealing rubber wears out, cracks, and heat escapes inside the refrigerator. It is desirable to check the seal for cracks all over the area. To seal the crack or replace the rubber band at all is simple. But it is not necessary to delay with it, otherwise the simple question may turn into a serious repair.
Magnetic valve breakage (in single compressors)
An annoying problem can occur in refrigerators with one compressor. The magnetic valve is responsible for making sure that the cold circulates evenly between the chambers. If the valve has failed, the compressor will start working more intensively. The temperature drops on the evaporator and ice appears on the back wall. Here, too, an expert from the service center is indispensable. Only he can understand the seriousness of the situation.
Capillary tube blockage
Frozen snow coat on the surface of the back wall of the refrigeration unit can clog sections of the capillary pipe. This could be thick accumulations of machine oil trapped in the tube. As a result. ice on the walls and constant work of the compressor. Here you need the help of a qualified technician.
If the problem is with the sensor
There is usually a sensor installed in electronically controlled refrigerators. This device monitors the temperature in the chambers and signals the compressor to turn on/off. If the sensor is broken, the engine starts to run nonstop and the refrigerator freezes very hard and can freeze a lot of ice. In this case it is better not to get involved and immediately invite a knowledgeable person.
If this problem is allowed to go unchecked, the compressor, which is working at its limit, will stop functioning altogether. Repair costs can be unpleasantly high.
If it’s the compressor
Practice shows that the compressor does not break down very often. Fixing screws can come loose or mechanical damage can occur.
The cause of compressor malfunction can be immediately recognized by such manifestations:
Improper operating conditions
May be due to forgetfulness or haste, but many users allow the refrigerated cabinet to be operated improperly. Not completely cooled products are put into the chamber. Overloading the freezer or leaving the liquid in an uncovered container. All this can lead not only to the appearance of ice in the chamber and puddles under the bottom drawer of the appliance, but also to more negative consequences.
Refrigerator compartment insulation is frozen
Frost on one area may indicate that the insulation in your refrigerator is freezing. The problem is caused by wear and tear in the rubber seals. It can be replaced completely or the damaged area can be repaired.
The device that measures the temperature in the refrigerator compartment is called a thermostat. It is needed to interface with a sensor that stops the cooling process. The thermostat can go bad due to a power failure. It can be replaced by yourself by purchasing it in advance from the household appliance department.
This cause is actual for the over-stockinged. It is the right thing to do, but don’t overdo it. If the chamber is clogged up with products up to the refusal, the compressor can not cope with its task. Motor is running constantly, stopping occasionally. Frost or ice appears on the rear wall of the chamber. To avoid this, the products should be evenly arranged on the shelves.
Overloading of the refrigerator causes the compressor to start working intensively
The starting relay is responsible for ensuring that the compressor switches on and off on time. If the relay is defective, the motor can fail to start. Or may start but immediately stops. You can not fix anything yourself, that’s why it is necessary to entrust the decision of this question to professionals.
Determine the disease by the symptoms
Inspection of the refrigerator must be performed by a specialist. But it is possible to define some reasons by yourself. For your convenience we give the table of the most frequent breakages and malfunctions of the refrigerator and their symptoms. You can roughly determine what’s wrong with the unit.
Inverter refrigerators, the motor (compressor) does not turn off. It works all the time, but at different speeds (output, power, intensity). In conventional compressors, the compressor switches on and off periodically. Read more about the differences between inverter compressors and conventional compressors in this article.
