To begin with, nothing appears from nowhere and disappears nowhere. The ice at the bottom of the freezer of the Samsung No Frost refrigerator appears due to the fact that the melted condensate simply has nowhere to go. In general, the following occur, the water drain channel that goes from under the freezing evaporator to the container on the motor is clogged. Many people think that this channel is clogged with some kind of muck, that is, due to the ingress of any debris. Yes, indeed, all kinds of herbs are stored in the freezer, such as parsley, dill and the like, of course, the leaves can get into the channel through which the condensate flows, but from experience I can say that this is extremely rare. Believe me, the condensate drain channel is clogged with debris in 10% of cases out of 100, in overwhelming cases the culprit for this behavior of the refrigerator is the freezing of the drain pipe. In the video below, I showed how a flexible additional defrost heater is installed. You should definitely watch this video, then we will analyze cases and questions from consumers of this equipment related to this disease

Watch the video why ice accumulates at the bottom of the freezer in the No Frost refrigerator

Let's return to the video and consider some of the nuances that are associated with the installation of a flexible heating element. For the first time this video was posted on YouTube, and now it's time to interpret it on my website, this video was shot by me personally, so I understand very well what I'm talking about. First, let's see how the additional defrost works and what it is for. From the video above, you should have learned that the refrigerant suction pipe from the evaporator passes in close proximity to the water drain pipe, as a result, the condensate drain pipe gradually freezes. This is the main reason why ice appears in the freezer. Next, we will consider the issue that is of most interest to everyone, that is, we will talk about the parameters and where to connect the contacts of our additional heater

1. Heating element power→ 30 to 80 watts can be used. The most important thing here is that it does not melt the plastics, that is, the drain tube. Take the heating element and connect it to electricity, if you can hold it in your hands when it is turned on, then it is quite suitable for defrost
2. Flexible heating element length→ Completely depends on the model of your refrigerator and the location of the freezer. If the chamber is at the top, then its length will be noticeably longer, since the heating element must be stretched along the entire drain tube. In general, take some long single flexible wire and try to install it in the same way as there will be an additional defrost. This way you will get the exact length. You don’t need to buy a butt, it’s better to let it be half a meter longer, the extra ones can be laid at the bottom of the freezing evaporator
3. Where to connect→ This heating element must be switched on together with the main defrost. So it is necessary to solder the ends of the additional defrost to the contacts of the main defrost

Well, in principle, that's all, as you can see, there is nothing complicated, the heating element itself can be bought in almost any specialized online store, the main thing is to know which one to buy. When you buy, choose one that will fit into a hole with a diameter of no more than 1 centimeter. Further I will answer some questions that sound in my workshop about this. I think thanks to my answers, you will be able to understand whether you need to carry out this procedure

I have a Samsung refrigerator with the No Frost system, after I bought it, about three years later, such crap began. In general, water constantly accumulates in the freezer, or rather, water appears first, and then it freezes. We have to defrost the refrigerator every month, although we used to do it once every two years. In general, so that the food does not deteriorate, we pull out the bottom drawer and pick out the ice from the bottom of the freezer. They called several masters, they shrug their shoulders and each time they change the defrost sensor and clean the water drain pipe from the freezing evaporator. It helps for a while, but then we notice back the appearance of ice.

If you changed the defrost sensor, and also cleaned the condensate drain channel and the result remained the same, then you need to install an additional heating element, you can see how to do this in the video above. Cleaning the channel and replacing the defrost sensor is unlikely to help you

Lately my Samsung refrigerator started to act up, the problem is that water started dripping from the top of the refrigerator. The freezer freezes perfectly, but at the bottom of the freezer, we recently saw ice. The fact is that we have not defrosted it for a long time, and closer to summer we decided that we need to prepare the refrigerator for harvesting berries. They began to pull out the products and they froze to the bottom of the freezer. We defrosted the refrigerator for 3 days, then turned it on. After 3 weeks, ice was again found at the bottom of the freezer, and in the refrigerator compartment, water began to drip again from above. The master changed the defrost sensor, as well as the clockwork, but things are still there. As before, water drips from above the refrigerator compartment, and there is ice in the freezer

A classic case for the Samsung No Frost refrigerator with a top freezer. Try again to clean the water drain channel. It is quite possible that something is sitting there, it is in such refrigerators that this happens quite often. If this does not help, install a flexible heating element, that is, an additional defrost. I think that the defrost sensor and the timer have nothing to do with it at all, most likely we are talking about freezing the drain pipe or clogging it with debris

Once a month I cleaned the drain pipe in the freezer, now the situation is aggravated by the fact that the spiral of the main heating element is covered, it does not ring at all and frost freezes on the evaporator. In online stores, such a heating element is not sold separately, only assembled with the radiator itself. I watched your video, I understood the principle of the system. I have such a question, but can we use such a flexible heating element as the main one, that is, wrap it around the evaporator and put it into the drain pipe. It seems to me, what's the difference what this radiator will heat

The difference is big, the fact is that the main heating element is in an aluminum case and stands on the evaporator itself, thanks to this, heat exchange occurs, if you install a flexible heating element, then there will be no such heat exchange and it is quite possible that ice will freeze on the freezer in the future. If you cannot find the original, then you can install the universal one. You can see it in the photo below

Photo of glass defrost heater for No Frost refrigerators

It is very important here that he sat down in size, and the rest, as you put it, does not matter to the evaporator that it will warm it. Do not forget about the additional heater, it must also be installed. If there was a freezing of the drain channel in your refrigerator, then it will continue to be repeated in the future, so it’s better to play it safe. When you buy a glass heating element, be sure to find out the dimensions and measure the length of the evaporator, since you will need to install it under the evaporator

America puts old refrigerators along the roads. Of course, this is not about Harlem. Rather, it concerns small cottage towns, where the wealthy stratum of the population lives. Refrigerators are quite working, just the owner decided to update the set household appliances at home, put the unnecessary on the highway. It is considered in the order of things to come, pick up the thing you like, or the waste disposal service will do it the next morning. An unimaginable standard of living allows Americans to stop thinking about why ice freezes in the refrigerator, despite the presence of the NoFrost system, just get rid of it by throwing out old trash.

Refrigerator operation diagram

The refrigerator lives by the circulation of freon, pumped by the compressor into the condenser. Under high pressure the refrigerant becomes a liquid, giving off heat to the kitchen air. Having passed into the evaporator, freon takes the heat from the interior of the refrigerator to the evaporator. The refrigerant becomes a gas and rushes back to the compressor. The cycle is carried out continuously, the difference between refrigerators shows how to use the fundamental principle in operation.

There are models:

1. With one or two compressors.
2. Two, single-circuit systems (we mean the freon circulation path).
3. With static, dynamic (forced) cooling.

Today we are going to consider the second branch of the last group, for completeness we will describe other variations along the way, so that the speech is clearer. The most impatient readers can skip ahead to the next subheading about the NoFrost system.

One vs two compressors

So... In a refrigerator there are usually two compartments, hermetically separated from each other (the systems considered today violate this principle). Each has its own temperature, optimal for food storage:

• refrigerating chamber 4 - 5 ºС;
• freezer -18 - -20 ºС.

It should be noted that the parameters were chosen for a reason. Temperatures require the use of state regulations for food products of various kinds. Defrosting of frozen semi-finished products is carried out at a temperature of about 5 ºС, which is very convenient, since most of the food is supposed to be stored at the same thermometer reading.

Modern refrigerators usually offer a range of values ​​to choose from, the owner of the device is free to find the right ones. Some models have freshness zones. The temperature is maintained close to the freezing point of water. Allows you to store almost any product intact for several days without losing quality.

One of the circuit implementations of the refrigerator is the presence of two compressors. Everyone works by cooling the compartment. Naturally, there are two contours of freon movement. Usually the evaporator is located right behind the back wall, there will be the coldest place. Gradually, due to the natural circulation of air, the temperature decreases. The process is called static cooling, ice usually accumulates on the back walls, and periodically needs to be cleaned off. Usually it is necessary to carry out the defrosting procedure.

But! The procedure is carried out for the freezer. In the refrigerator compartment, condensate forms on the back wall (evaporator area), it does not turn into ice. Drops gradually flow down, bypassing the drainage channel, into a special bowl, standing under the refrigerator. The freezer is freed from frost in a similar way. Cooling is turned off, the temperature gradually rises, water flows down the drain, and is collected by hand with a rag. No problem.

Trouble starts when drainage tube it gets clogged at the bottom, water begins to collect in the pan, the first sign: it's time to start cleaning. Ice does not form, just a small flood. It is allowed to clean the drain with a thick fishing line (1 mm or more), similar material that is unable to damage the drainage tract.

This is how refrigerators equipped with two compressors work.

Two circuits vs one

Refrigerators with one compressor function in a similar way. For each compartment, one freon movement circuit is created. The evaporators are located directly behind the back wall. Therefore, frost constantly forms in those areas, this is normal. It happens that ice freezes on the wall of the refrigerator. This means that the temperature set by the owner is too low. A suitable option: the thermostat has broken down, it becomes noticeable by strong deviations of the operating parameters from the set ones.

The operation of the equipment is characterized by cyclicity, the frost slowly melts when the compressor is turned off. The modes are calculated, ice is not formed by the back wall of the refrigerator. In the absence of the NoFrost system, the maximum that can disturb is the water of the pan. Fact means: it's time to clean the drain. It just clogged, preventing the liquid from draining.

The freezer, of course, will have to be thawed from time to time. Indispensable attributes of static cooling. It doesn't matter if there are two compressors in the refrigerator or only one.

NoFrost refrigerators

NoFrost works on a different principle. The creators wanted in advance that frost and ice would not form in the compartments. Moisture has to be removed. It is achieved by the fact that the evaporator is placed in a special compartment, invisible to the user's eyes. Hiding in the space between the walls. To enhance air circulation through the hidden compartment, a special fan is used. The flow enters from one side, exits from the other, bypassing the ventilation holes.

Moisture settles on a cold evaporator, therefore, the walls of the chambers remain clean. To defeat the frost that has covered the evaporator, a defrosting unit of special heating elements is built in. Due to the high-quality thermal insulation of the hidden compartment, the temperature of the chambers remains unchanged. Water flows down through a special drainage path, often symbolically separated from the path of frosty air.

Such a scheme makes the products dry out with lightning speed in NoFrost refrigerators, take the trouble to wrap the food in bags, pack it in containers. As for the freezer, semi-finished products remain pristine, since frost has ceased to form. Products do not freeze to each other.

However, this convenience sometimes comes at a cost. The refrigerator is covered with ice. This happens when the bottom of the drainage. Let's take a closer look at the mechanism itself.

Why ice forms in the refrigerator with NoFrost

Why ice forms in the NoFrost refrigerator. In other models, the effect is absent (in the refrigerator compartment).

The point is in the peculiarities of the location of the evaporator, blowing. Depending on the schema, it looks like this:

1. The freezer is located at the top, the refrigerator compartment is at the bottom. A hidden compartment is built in between them. In the refrigerating chamber, air is taken in from above, the evaporator passes (leaving frost), the fan drives it behind the back wall, enters inside from below, near the pallet.
2. Each compartment has its own evaporator. There are two drainage labyrinths. The solution is more reliable. Practice shows: the solution is not ideal. We will return at the end of the review.

Now let's see what happens in the NoFrost refrigerator with one central evaporator. Firstly, the flows from both compartments mix at one point - where the frost settles. Therefore, the smells of the freezer and the refrigerator are mixed. Separate inconvenience. The temperature is controlled by the amount of air passing through. For a freezer, the value is larger, despite the smaller volume of the compartment.

When defrosting, heating is switched on. The evaporator frost becomes moisture flowing down the same path (or near) that the air travels. The special relief of the tract will ensure a reliable flow of liquid into the container under the refrigerator. The process proceeds normally until a slaughter occurs. Somewhere below. After moisture is collected near the drain hole, hidden from the eyes of the user of the refrigerator. Then the cooling cycle starts. Frosty air begins to flow along the path, moisture immediately freezes, turning into an ice plug.

The process is on the rise, at the next cycle, the water is poured into the lower refrigeration compartment through the ventilation holes. Moisture can accumulate behind the wall, causing an avalanche-like process of ice accumulation. Ultimately, there is ice in the tray inside the refrigerator, ice in the back of the chamber on the wall of the refrigerator, and the cavity inside the space between the walls is clogged with ice.

The problem is easily cured. Take the trouble to defrost the refrigerator by unplugging it (remove food). Then clean out the drain.

Noticing this problem, manufacturers began to produce Low Frost (Frost Free) refrigerators. The branch of forced airflow is used for the freezer. The refrigerator compartment is defrosted by the drip method (see the beginning of the review). Eliminates questions about why there is ice on the refrigerator wall.

Not all refrigerators are equipped with the No Frost system, and dripping ice in the freezer does not surprise anyone, because it is defrosted manually. But what if this problem arose in modern models? You need to find the cause of the problem and fix it. In the article we have collected all the possible options.

Why does ice form in the freezer

If the No Frost defrost system is installed in the Samsung, Bosch, Ariston or other brands refrigerator and a snow coat freezes in the freezer, it is not necessarily a breakdown. You may be using the device incorrectly.

• Look at the control panel. Have you set the mode to "Super Freeze"? In electromechanical models, it is turned off manually. The compressor will continue to pump cold until you cancel the setting.

• Check temperature controller. The temperature in the chamber should be from -17 to -19 degrees. Otherwise, the compartment will be very cold, snow may form under the freezer, and the motor will wear out. Adjust thermostat. Even if the room is too hot, do not set a low temperature - when the technique is chosen correctly, it itself reaches the desired performance.

Minor problems include wear on the seal on the door. Warm air penetrates into the cracks, the performance in the department increases. The compressor works with a double load, pumping cold, so snow freezes on the walls.

If the door is not closed tightly, or the seal is leaking, a red light may flash on the panel or a signal may sound.

Tires need to be replaced. Perhaps it does not adhere well to the body, because it is clogged. You can wash it with warm water and soap, and wipe it with ammonia.

Sagging hinges also lead to a loose door seal. Then most of the ice will collect on the edge, near the freezer door. You can tighten the loops yourself.

Flashing of the red indicator occurs after the camera is loaded. If you put a lot of warm food in the compartment, wait until the temperature has recovered.

What malfunctions require repair

Frost in the compartment may indicate a breakdown. Be careful and you will be able to find the problem.

Clogged drain hole

Snow accumulates at the bottom of the freezer. There may be water in the refrigerator with No Frost at the bottom under the drawers. After turning off the motor for rest, the evaporator heating element is turned on and the ice is defrosted. All moisture flows into the drainage hole and is removed from the system. The drain could be clogged with small debris, crumbs. It needs to be cleaned up.

On some models, the opening is located behind a panel that must be removed first.

You can clean the hole with a thin wire or a syringe with water.

Faulty defrost system

At the same time, the back wall is covered with a snow coat and ice. Failure of any component of the evaporator - heater, timer, fuse - leads to a lack of defrost. Therefore, the evaporator is covered with snow. The channel, which is responsible for the supply of cold, also freezes, so the temperature in the department begins to rise. You may notice that the compressor turns off less and less.

It is necessary to inspect, diagnose the parts of the evaporator. This will require special equipment, so it is better to contact the master.

Temperature sensor failure

The compressor rarely turns off "to rest". The walls of the freezer compartment are overgrown with ice and snow if there is a separate thermostat or compressor. If there is one control for both chambers, then ice may also form on the back wall of the refrigerator.

When the temperature sensor breaks, the control board does not know what the temperature is in the chamber. Therefore, it gives the command to the motor to pump the cold more.

The temperature sensor needs to be replaced. Additionally, a fault code may appear on the display. To check the sensor for serviceability, you must completely defrost the refrigerator. Diagnostics is carried out with a multimeter. The resistance should be 4.7 kOhm.

Refrigerant leak

The continuous operation of the compressor leads to frost on the evaporator. However, the temperature is still too high and does not reach the set level. If you perform defrosting, the refrigerator may stop turning on.

A constant leak of refrigerant in the evaporator leads to ice build-up and non-stop operation of the motor. After all the gas has evaporated, both chambers will stop working. Therefore, you need to find the cause and location of the leak. The master will deal with this best, he will repair the damaged area and refuel the system with freon gas.

If you notice that frost is growing in your refrigerator with No Frost, sound the alarm, this is not normal. Try to defrost it yourself and check the above details, or contact the service center.

Refrigerators that need to be manually defrosted and washed monthly are a thing of the past. Modern models are equipped automatic system defrosting, which performs its functions unnoticed by the owners. True, manufacturers still recommend defrosting the refrigerator 1-2 times a year manually for prevention purposes. And yet, with automatic defrost technology, this preventive treatment will not resemble the conquest of an icy peak. mountain top- parts of the refrigerator are covered with only a slight frost coating.

The most common automatic defrosting technologies are drip (weeping) and windy, which is called No Frost. The drip defrost system is most commonly found in modern refrigerators. Its essence is as follows. An evaporator is installed on the back wall of the refrigerator compartment (drip technology is not used for freezers). Usually it is hidden inside the wall itself, since the products should not come into contact with the evaporator - this worsens its operation. In this case, water may not drain into a special container, but to the bottom of the chamber. In addition, an "open" evaporator can be accidentally damaged. The evaporator maintains a low temperature rear wall, due to which water vapor condenses on it and ice floes form. This does not happen with other walls. At the end of the refrigeration cycle, when the compressor stops, the evaporator heats up. The ice accumulated on it thaws, and the water flows into a special container along the grooves. When the compressor starts up again, the water in the tank heats up and evaporates. The process starts over with a new cooling cycle.

In refrigerators with the No Frost system, the evaporator is installed behind the back wall of the refrigerator compartment or above the freezer compartment. It is equipped with fans that circulate the air inside the refrigerator. The evaporator, as in a refrigerator with a drip system, provides a low temperature of the back wall. When the compressor stops, the frost thaws and evaporates.

So what are the advantages and disadvantages of No Frost? Many people think that due to the airflow system in refrigerators with the No Frost system, food dries out faster. From a theoretical point of view, this may be true, but in practice there is not much difference. In different models of refrigerators with a drip system and No Frost, products remain fresh for different times, but No Frost technology does not have a strong effect on this.

There is an opinion that refrigerators with the No Frost automatic defrosting system do not need to be defrosted manually at all. But this, again, is not true. Refrigerators with both drip and wind systems should be defrosted once or twice a year.

The main feature of the No Frost system, which is called its main advantage, is the uniform air temperature inside the refrigerator. The temperature difference on the upper and lower shelves of the refrigerator does not exceed two degrees Celsius. For comparison: in refrigerators with a drip system, the difference can reach five to six degrees. And in freezers not equipped with No Frost - up to nine degrees. Uniformity of temperature provides the best safety of products.

Another important advantage of No Frost is that the system works both in refrigerators and freezers, while the drip system can only work in refrigerators.

The ventilation system allows the refrigerator to recover temperature faster after the door is opened. However, this is not too noticeable - the power of the refrigerator plays an incomparably large role here.

Among the shortcomings of No Frost are called relatively high level noise at work. Fans provide additional noise. However, some models of refrigerators with the No Frost system are equipped with very quiet fans, which makes them much quieter than some of their drip "brothers".

A rather important drawback of No Frost is that the bulky evaporator mechanism “eats up” the volume of the refrigerating chamber. As a result, similar refrigerators with a drip defrosting system are noticeably more spacious.

A refrigerator with a No Frost system, ceteris paribus, consumes more electricity than a refrigerator with a weeping defrosting system. The difference in electricity bills will be small, but for those who are used to saving wherever they can, this is still a disadvantage.

Refrigerators with a drip system and No Frost differ in price. A refrigerator with windy defrosting technology will cost a little more than a similar model with "weeping" technology. However, this difference is also not very significant.

In general, the advantages and disadvantages of the No Frost system (compared to the common drip system) almost balance each other out. Therefore, the automatic defrost system is usually not a decisive criterion when choosing a refrigerator. But the advantages and disadvantages of different systems are still worth taking into account.

The practice is such that this is a very unpleasant and extremely common defect. Excessive ice formation forces endless defrosting, the quality of the products stored inside deteriorates, and the usable volume suffers.

If you notice that the unit began to require defrosting much more often, you should think about its good condition. Ice itself is just a sign of much more serious problems. To avoid unnecessary headaches, first I will tell you why a snow layer can form precisely through the fault of the user.

If ice appeared on the back wall of the refrigeration compartment, then this disease is more common in units with a drip defrosting system in the refrigeration compartment (, Hotpoint-Ariston, etc.). Frost leads to a violation of the correct mode of storage of products and malfunctions of the device. The fur coat will thaw, and the equipment will leak. Defrosting or chipping ice is not the solution. If you carry out these manipulations, the ice will eventually begin to grow again. It is necessary to look at the root, since a fur coat is a consequence of the breakdown of any components of the refrigerator.

The source of the problem may be the inclusion of maximum cooling in hot weather. Such users are guided by the fact that the most low temperature inside the chambers it is better to keep food inside the refrigerator at +30°C outside the window. However, the temperature inside the refrigerator and freezer does not depend on the heat in the apartment. It is not necessary to transfer the unit to a wearing mode of operation for the entire summer period. This will lead not only to the formation of a "fur coat", but also to more serious problems.

The second point is the constantly activated superfreeze. There are models where the mode does not know how to turn off on its own and this must be monitored. At this rate, the compressor works almost without turning off, the unit freezes by 200%. The freezer is the weak link.

The third point is the violation of the rules of operation. To prevent the formation of snowdrifts inside, do not put hot dishes inside. Food and liquids must be covered, as otherwise evaporation will occur, which condenses on the back wall of the refrigerator compartment.

If there is a small layer of frost that thaws, this is the norm for equipment with a drip defrost system. In all other cases, it makes sense to look for a malfunction.

To get started, it would be nice to carry out a few simple steps:

• monitoring the operation of the unit for several days;
• it should be noted exactly where the fur coat freezes, how thick, the rate of ice formation.

The causes, sources of breakdowns and principles of repair, I will consider below.

Temperature sensor failure - snow in the freezer

The unit begins to behave inappropriately, it practically does not turn off, it freezes almost continuously. The layer of snow grows in the freezer. The fact is that a broken temperature sensor reports that it is too warm inside and the device starts the cooling cycle again. This usually happens in .

Solution: the temperature sensor is replaced with a new one. In domestic refrigerators, the question will rise at 2.5 tr, in European ones - from 4.5 tr.

Temperature sensor failure - snow in the refrigerator compartment

Almost the same picture is observed here: the motor works with short and rare interruptions. The refrigerating compartment is heavily frozen, and the ice does not come off the back wall. This is due to the same sensor. but the refrigerator compartment. The compressor is forced to freeze above the measure and the compartment is significantly supercooled. The air temperature sensor breaks down, which measures the temperature directly in this compartment.

Solution: Replace a damaged sensor. The asking price is the same.

Faulty thermostat - frost in two compartments at once

This happens in refrigerators with one thermostat for both compartments. Snow and ice form in both the freezer and refrigerator compartment. Compressor almost never turns off. I note that the thermostat is in the evaporator. Its breakdown deprives the compressor of a signal that cooling should be completed, which leads to the indicated consequences. This is a typical problem.

Solution: practice is such that a complete replacement of the node is required. The price of work and spare parts varies between 2-3.5 tr.

Clogged drainage hole - ice on the bottom

If the refrigerator is equipped with a drip defrosting system for the refrigerator compartment, water accumulates under the unit and under the vegetable boxes. An ice layer forms on the bottom of the freezer compartment.

In 99% of cases, the source is a clogged drain. This prevents moisture from escaping into the bath under the appliance and evaporating naturally. That is why the liquid accumulates at the bottom of the compartments, forming ice.

Solution: Cleaning the drain hole. This repair can be carried out independently or invite a specialist. The cost of the service starts from 1 tr.

The automatic defrosting system is broken

This issue may occur in . In this case, the back wall of the freezer is covered with a thick layer of ice. The compressor does not fade and runs almost continuously. The temperature in the freezer is several degrees higher than the set temperature.

If the unit has full automatic defrosting, poor cooling and a snow coat are also observed in the refrigerator compartment. For more modern technology the temperature malfunction indication flashes, the device may squeak about the problem.

I note that the breakdown of the defrosting system is a loose concept. Here the timer, drip tray, thermal fuse, defroster or heater may fail. Each faulty node blocks the unit from going into defrost mode. The evaporator slowly freezes, its performance drops, which leads to an increase in temperature. To compensate for this shortcoming, the motor runs more often, which leads to a vicious circle. The evaporator is covered with an even greater layer of ice, as are the walls of the compartments.

In addition, I will say that in systems with full automatic defrosting, the cold air supply channel suffers, which is why the equipment also cools the products poorly.

Solution: the only way out is to replace defective elements. Diagnosis is needed to identify the problem. Such a repair will cost a pretty penny. The cost can vary from 3 to 8 tr, which depends on the total number of broken nodes.

Freon leak - a snow coat inside two chambers

When a refrigerant leak occurs, the cooling capacity of the machine drops significantly. To eliminate this shortcoming, the compressor begins an almost continuous stroke. As a result, a snow coat grows inside the chambers. When the remaining refrigerant is completely evaporated, the motor stops working.

The most vulnerable places:

• in the areas of factory rations (connections);
• in the evaporator of the refrigerator compartment;
• in the freezer heating circuit.

The symptoms of a leak are revealed in different ways:

• in the areas where the freezer evaporator goes, an uneven, but rather massive layer of snow is formed. The compressor plows without interruption, but the temperature inside the compartment is too high. The unit can squeak and signal with an indication. If you defrost, the refrigerator stops working altogether;
• the refrigeration compartment also suffers. An uneven layer of ice and snow accumulates in it, the other signs of failure are identical to those described above.

Solution: you should involve the master so that he finds and fixes the leak. The system needs to be recharged with Freon. If a leak occurs in the evaporator, it is replaced with a new one. Repair costs can exceed 8 tr, which is also not cheap.

Deterioration of the rubber door seal

If this trouble happened, ice and snow accumulate on the walls closer to the door. The temperature inside the chambers is higher than the set one. In the refrigerator compartment, frost and snow spread to the rear wall. The alarm indicator may flash.

The main symptom of a problem is a loose door closing. Warm air enters the refrigerator freely. The compressor begins to compensate for the heat, which causes more ice to form.

Solution: everything is simple here - just change the seal. This question will arise at about 2.5 tr.

Partial blockage of the capillary pipeline

This leads to difficult circulation of freon in the system. Because of this, a layer of ice builds up on the back wall of the refrigerator compartment. There is poor cooling in the chamber itself. The engine runs with rare pauses. If the model is smarter, the indicator starts flashing and a squeak is heard.

Solution: the main task is to remove the blockage formed as a result of the burning of the oil circulating through the system. The pipeline is cleaned only by the master, the unit is charged with refrigerant. If required, change the oil. Issue price - 3.5-6.5 tr.

Solenoid valve failure

If your refrigerator compartment starts to freeze, the valve is probably out of order. In such a situation, a snow coat always grows on the back wall. The temperature is getting higher than normal.

In general, the valve controls the variable cooling of the compartments. If it is stuck, freezing begins in one, in the other, on the contrary, underfreezing.

Solution: the valve is replaced with a new one. The cost of repairs starts from 3.5 tr. and can go up to 8.

Freezing insulation of the refrigerator compartment

If the thermal insulation is constantly wet from condensate, it is broken. This leads to the fact that in a certain place of the rear wall of the chamber, a thick layer of snow and ice grows unevenly.

Solution: the frozen section of the insulation is cut out and replaced with a new one. This is work for a professional, which will cost about 8 tr.

Unbalance door fixing system

The doors of any refrigerator are hinged. When the fasteners weaken and sag, this leads to a violation of the fit. Warm air begins to flow into the compartments. The main volume of ice accumulates near the doors.

Solution: replacement or balancing of fasteners. A possible solution is to re-hang the door where possible. The repair price can reach 4.5 tr.

What is the result

The main advice from the master: all operating standards must be observed immediately after buying a refrigerator. Do not rely on "maybe" in this matter. Even the most modern units with full automatic defrosting need to be defrosted once a year. If a breakdown does occur, some of the problems can be fixed on their own. However, don't procrastinate, as a thin layer of snow can result in major problems that require costly repairs.
