Why is there snow on the wall of the refrigerator?

Refrigerator Repair: Why Does my Refrigerator Have a Frost Buildup?

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:

  • Improperly selected cooling mode. Especially it concerns the users, who think that in the heat it is necessary to set the lowest temperature mode. It ends up with a frozen wall. As for the freezing mode, this should not be used on hot days.
  • Constant formation and melting of a light layer of frost. This is also not a malfunction if the defrost is “drip” type. You can confidently use the refrigeration equipment (hereinafter. CO).
  • Improper operation. Ice on the back wall of the “Indesit”, “Samsung”, Bosch (and other brands) can grow due to neglect of the manufacturer’s recommendations. If you load the shelves with unrefrigerated foods without a lid or if you put a lot of opened containers with liquid, the water will evaporate and collect as droplets on the rear wall. When the cold circuit is running, the droplets will turn into ice, which will thaw when the heating starts. If the drain hole is not clogged, the water will flow down the drain without causing problems. And if the drain pipe is clogged, the water will go under the drawers, creating more difficulty. Because of the excess moisture in the chamber, the ice will be more and more.

When all these reasons are excluded, but the snow or ice still does not come off the wall of the compartment, it means that there is a breakdown. On this page you can find out what kinds of defects can cause freezing of the evaporator.

The ice is freezing on the back wall of the fridge?

Why the freezing of the refrigerator back wall is a rather frequent phenomenon. Sometimes it happens due to the malfunction of the device, but in half of the cases it is caused by the carelessness of the owners. It is required to call a master or to apply to a workshop only in those situations when to eliminate the problem on your own it is not possible. That is why let’s analyze typical factors that create this problem.

Today the majority of modern models, popular at our market of manufacturers (Ariston, Atlant, Bosch, Electrolux, Indesit, LG, Snaige, Stinol, Nord, etc.) have a defect.) are equipped with the No Frost cooling system. In them a fan blows dry air through the compartments, preventing the formation of frost. If the ice on the back wall of the refrigerated compartment does begin to grow, you should conduct a complete inspection of the entire unit and make further decisions.

Frozen refrigerator: causes and ways to eliminate the snow “coat

If you have detected ice on the back wall of your refrigerator do not panic. this is one of the most frequent malfunctions of refrigerators of any brands (Minsk, Atlant, Biryusa, Indesit, Stinol, Bosch, Beko, etc.).).

The rear wall of the refrigerator is most often covered with snow in the models that are equipped with the drip defrosting system of the main compartment.

Any failure does not pass without a trace for all the systems and units of the appliance, so the formation of ice necessarily affects the operation of the refrigerator, its functionality and the quality of food storage.

So, if there is ice frozen around the food in your fridge, there is a high probability that the food will soon become ice-cold, and after defrosting it will hardly be distinguished by its perfect taste and attractive appearance.

Well, of course, sooner or later, the snow “coat” will think to melt, and your refrigerator will begin to leak.

If you think that normal defrosting and manual breaking of ice will help to get rid of ice block for a long time, it is not so, especially if the freezing block has appeared not because of errors in operation but because of breakage of important blocks of fridge unit. If you take your time and manually scrape away the ice in the fridge compartment, your efforts will be wasted. frost may soon appear again.

Why ice forms

Why the back wall of the refrigerator is freezing? There are a variety of causes. To determine this accurately, you need to know exactly where the ice is growing. Only after determining the exact cause of the problem can you begin to repair your refrigerator. Ice appears for the following reasons:

If the defrost sensor stops working completely or partially, snow or ice forms on the back wall of the unit. If the sensor is working properly, the frosting can last up to 15 minutes. It melts in the next 30 minutes. This happens with a single-compressor refrigerator. Frost on the wall of the two-compressor fridge can keep up to 35 minutes. If to put a hot dish in the device it will reflect on refrigerator work too. A plate with freshly baked patties or hot soup in the proximity of the sensor can simply put it out of operation. As food cools, it will leave moisture droplets on the walls, which turn into ice crystals.

If your refrigerator has ice freezing on the side walls, it means the gaskets are worn out. There are different ways to replace the sealing rubber. It is often installed in special grooves. Then it is necessary just to remove old gasket and insert a new sealing strip in the groove. It does not need any fasteners. In other cases, it can stick to the door or be stuck to it at several points.

Ice freezes on the back wall and when the compressor malfunctions. It can happen when the refrigerant leaks from the system. The compressor starts to work almost without rest. Its constant operation causes the temperature to rise in the chamber, leading to snow and ice on the walls.

The above causes of the fact that the wall is covered with snow and ice are reasons to invite a specialist to fix them. From such cases buying new equipment can save. It is usually equipped with a No Frost system. These units are Ariston, Bosch, LG, Stinol, Atlant, Electrolux, Indesit, Nord, Snaige and some other brands. In their chambers the fan blows dry air that does not let the snow crust to form on the walls. But not everyone has such an opportunity. Then the refrigerator has to be defrosted by yourself.

When replacing the sensor, you need to buy it from a reputable vendor. It is better to do it in a service center. Many parts seem to be exactly the same in appearance. Only some letters and numbers differ in their designation. But these are the reasons that can completely put the fridge equipment out of operation.

Why the ice is freezing on the fridge rear wall

There are 6 reasons why ice freezes on the fridge rear wall:

  • Frozen insulation of the back wall.
  • Freon deficiency.
  • Thermostat malfunction.
  • Capillary tube is clogged.
  • The electromagnetic valve is broken.
  • Leaks (rubber seal is worn out).

It is possible to determine the cause even before calling a master, the malfunctions manifest themselves in different ways:

Why does the fridge freeze

Often the users are perplexed why there is ice on the fridge rear wall irrespective of the fact how long since the last defrosting. We will answer all questions and will help to avoid occurrence of a snow “coat. But before doing so, be aware that this phenomenon must be dealt with as soon as it is detected, since permanent frosting of foods can lead to a reduction in their flavor and health benefits.

Do not try to splinter, break or constantly defrost the unit. It will not solve the problem, but only damage the important parts and reduce the service life of appliances. First of all it is necessary to find out why the ice in the fridge is frozen because of malfunction or breakage.

Normal operation of the refrigerator and frost inside

If the refrigerator with a drip system of defrosting (Indesit, Atlant, Nord and others) the periodicity of moisture drainage and its freezing on the back wall is normal. The principle of work of such system consists in that it freezes moisture for some time, cooling internal space, then this moisture defrosts and drains into the special hole in the bottom. This is how it works. But these frosts are small and disappear very quickly.

And here is why the snow in the form of “coat” forms on the wall of the refrigerator, it is necessary to understand:

  • Cooling mode set to maximum during hot weather. There is a common misconception that if it is hot, your fridge needs more power to prevent the food from spoiling. The consequence of this misconception is a coating of frost on the rear wall of the refrigerator compartment. To solve this defect, you need to defrost the fridge and turn it on again, in the normal mode.
  • Excessive food load. When the unit is difficult to cope with its function because of the large amount of food inside, then from intensive operation icing of the wall is formed. You need to defrost the appliance to work properly, and avoid overloading it with contents during further operation.
  • Warm food in the refrigerator. Foods that are warmer than room temperature should not be placed in the refrigerator. Moisture evaporates from them, it covers the walls and ices up, plus it puts extra stress on the unit itself. Snow “coat”. a sign of its improper use. Actions in this case are the same as in the previous two.
  • Ajar door that was forgotten to close. Warm air inlet causes icing.

When these causes are eliminated, and the snow still collects, it means that there is a breakdown, which only a specialist can deal with.

Snow or frost on the back wall of the fridge?

This is the question that most fridge owners try to answer when faced with snow or ice on the back wall of their refrigerator. It seems to be all quite natural. it is cold in a fridge and that is why a snow coat is formed there over time, isn’t it so?? But, let me agree with this statement and say that far from always it should be so. If we are talking about the old “grandma’s” refrigerators, there is nothing to do about it. the snow is freezing and will keep on doing that. But it shouldn’t be like that in modern units. Especially if their fridge has the No Frost function. That is why if you have noticed that the evaporator is covered with a layer of snow or if you have noticed even a very little frost on the inside wall of the fridge. on the back wall. it already can be a reason to sound the alarm.

Snow on the refrigerator wall, proper defrosting

We will talk about the breakdown when snow or ice freezes on the back wall inside the refrigerator compartment.

This malfunction has different names: ice on the back wall of the fridge, snow on the back wall, even ice on the wall of the fridge or ice on the refrigerator.

The causes of formation of the snow coat in the refrigerator

In modern refrigerators with the electronic control the defrosting process is monitored by a special temperature sensor. Its breaking off leads to the fact that the back wall freezes as a snow coat or ice.

After replacing the sensor with a new one, the freezing stops and the operation of the refrigerator completely returns to normal.

The reason of ice formation in the fridge compartment can be caused by the refrigerant leakage from the unit. Due to loss of cooling capacity, fridge never switches to defrost mode and ice formation goes on day after day (large ice coat forms in a week).

The snow coat in the fridge is often formed if the door opening is poorly sealed. In these cases, the sealant must be replaced with a new one.

The same coat can form if the fridge is used incorrectly: there are liquids in open vessels kept in the chamber or foodstuffs that have not cooled down to the room temperature.

Also, ice in refrigerators can form when the refrigerator door is often open, and even more so for prolonged periods of time.

Modern household refrigerators have different systems of defrosting the evaporator. The drip defrost systems and the “No Frost”, “Frost Free” and “Full no Frost” systems are now common.

Of course approach to fridge defrosting in systems with different methods of evaporator defrosting should be different.

Let us begin with the refrigerator with the “drip type” of defrosting. Refrigerators with “weeping” evaporator.In such refrigerators, a distinction should be made between medium temperature defrost and low temperature defrost.

Regarding the medium-temperature compartment. There should not be any greater snow coat on the evaporator fin of the medium temperature section! And, of course, there is no need for defrosting.If on the evaporator lobe of your fridge there is a big snow coat, then as a rule, it means that either you put into the fridge compartment a lot of warm and non-packed food, or there are problems with the tightness of door closure in the fridge. Check that the rubber seal is in good contact with the interior of the freezer, particularly in the corners.

Why is Your Freezer Frosting & Fridge Freezing

Now to the low-temperature compartment.In systems with “drip type” defrosting, defrosting the freezer compartment manually is imperative! There’s no automation!But it needs defrosting very seldom. only a few times a year. How often. It all depends on the specific conditions of use. The less frequently you open the freezer door, the less you defrost it. Usually. 1 time in the winter and 2-3 times in the summer. In general, use a simple rule: as soon as the snow on the evaporator starts to cause you inconvenience (interferes with getting the food, pulling out the drawers). defrost!

When manually defrosting the evaporator of a low-temperature compartment, do not make the most common mistakes. Use the well-known recommendations:. Switch off the fridge for the defrosting period. Do not use knives, forks, wooden sticks to unscrew ice to speed up defrosting. And do not take away thawed ice with your hands. Remember, evaporator walls are very thin and it is easy to destroy them, but it is difficult to repair the evaporator. Expensive;- Expedite the defrosting process by placing a container of warm water in the freezer is possible, but the water must be exactly warm, not hot. It is better to put the container with water itself on a wooden board or a cloth;. It is possible to use a fan and a hair dryer, but the air heating in the hair dryer must be switched off;. The main piece of advice is: do nothing and let the fridge defrost by itself in order not to make a mess!After getting rid of the snow coat and after a thorough cleaning of the refrigerated compartment, it is not necessary to load food immediately. Let the refrigerator run for at least 30-40 minutes. Thus you will facilitate the start-up of the refrigerating machine. This recommendation is especially topical when defrosting the fridge during the hot period of the year.

Defrosting of refrigerators equipped with the “No Frost” system.I would like to stress right away that common opinion that fridges with “No Frost” system requires manual defrosting at least once a year is wrong!In such refrigerators the defrosting of the evaporator is fully automatic. If the defrost system fails, you feel it almost immediately. The temperature in the refrigerated volume will start to rise. In other words. The refrigerator will break down.Of course, the lack of manual defrosting of refrigerators with the system “No Frost” does not mean that they do not need to do sanitation.
