There are various options for freezing systems. For some of them, freezer belted with ice is a normal occurrence. The condensate cools and settles on the surfaces. But if ice forms in the freezer of the refrigerator when using the know-frost system, then this indicates a violation. The use of the latter involves the removal of condensate from the freezing compartment.
How is ice formed, and how to remove it?
How does know frost work?
This is a fully automated system that eliminates human participation in its work. The defrosting of the refrigerator occurs according to the calculated algorithm using special mechanisms. The system independently conducts a defrost in forced mode. This is done in a hidden way.
In this case, the freezing compartment is ventilated. Due to the presence of a mounted drip device, condensate is constantly removed from the refrigerator, as a result of which it does not leak. Violation of the output mode may cause the formation of ice on the surfaces of the freezer.
The idea of creating "NoFrost" implies the exclusion of situations in which ice is formed. For this, a special moisture removal technology is used. A heat exchanger is integrated in the cavities of the side walls. Strengthening the processes of air movement occurs due to the built-in fan heater.
Condensate during operation is delayed by the heat exchanger, which has a reduced temperature. Due to this, the chamber walls remain dry and clean. Hoarfrost that occurs on the evaporator is removed in defrost mode. This is due to specialized heating elements.
The use of the know frost system in the refrigerator requires taking into account some features of how the products should be stored by the owner. Due to the nature of the work, in which there is a constant movement of air, a quick airing of the stored will occur. Accordingly, before you put food in the refrigerator, you need to close it from external influences (i.e., put it in a container or wrap it with plastic wrap).

Why is ice formed?
One of the probable causes of frost can be a power outage. The mains voltage has disappeared, so the refrigerator does not freeze. As a result of downtime, a puddle can occur, the fact that it appeared is not always clearly visible and may be left without attention. After recovery, it freezes and ice forms.
Setting the maximum freezing mode can lead to untidy consequences. When the door is opened, hoarfrost forms, which begins to thaw and drip down, resulting in ice formation.
In order to avoid this, it is recommended to keep the average freezing temperature. This will not only prevent the occurrence of frost, but also save some electricity. According to the recommendations of most manufacturers. This mode of operation is the most optimal.
When the door is opened, hoarfrost forms, which begins to thaw and drip down, resulting in ice formation.
Naturally, opening and closing the door is not the only circumstance leading to the occurrence of icing. Among the causes of this phenomenon may be the following:
- Violation of the sealing of the door seal. Wear on the rubber seal may cause the door to not fit snugly against the refrigerator.
- Another reason that ice forms in a refrigerator with the NoFrost system may be a clogging of foreign channels leading out of the water exchanger. Also, one of the nozzles could trite out, as a result of which moisture does not get into it and water does not move to the container to collect moisture.
The container itself, as a rule, is located in the same compartment with the motor. Water from it evaporates naturally. The occurrence of icing may be due to the fact that the resulting water does not fall into the required place, but is poured into the freezer. There she accordingly freezes safely.
- Violation of the heating element of the heat exchanger, that is, its combustion. In this case, no one but a service technician can help.
Important! If the appearance of ice is noted regularly, and the refrigerator is still under warranty, then do not look for reasons. Moreover, carry out independent repairs. Contact your dealer for troubleshooting or replacing a technical device.

How to defrost?
Owners of modern refrigerators with a know-frost system note that the defrosting procedure on some models has to be done quite often. In order for this procedure not to lead to a breakdown of the technical device, it should be carried out correctly:
- The first thing you should start with is disconnecting the refrigeration unit from the power source. That is, pull the plug out of the outlet.
After defrosting, you will have to turn off the refrigerator, even pulling the cord from the outlet
- The ice that has formed can cause a desire to remove it mechanically: cut it with a knife or scrape it off with any other hard object. In no case should this be done.
The wall thickness of the heat exchanger is small. To inflict damage on it by mechanical action is not difficult. As a result, the problem will develop into a completely different direction. You will have to contact the after-sales service for repairs, which will be expensive.
- Acceleration of the defrosting process can be achieved by using a container with warm water. The use of boiling water is excluded. If the water temperature is close to 100 degrees, its effect on the surface of the refrigerator can lead to damage. It is recommended to install the container on a woven material or on a board. You can use a hair dryer to dry it quickly, but first you need to make sure that the heating function is not turned on.
Some users of refrigerators are afraid that their defrosting can lead to breakage. In this situation, you can entrust the procedure to the technical device itself. After the defrosting process is over, a person will only need to remove excess moisture.

Next, you need to withstand the time (about half an hour) before returning the products to their places. This is necessary so that the refrigerator returns to standard operation. This is most relevant in the warm season.

Remember! Refrigerators with NoFrost require defrosting only when there is any malfunction. The main advantage that was pursued during the development of the system operation process is the absence of the need for defrosting due to the removal of moisture by the technical device itself.
Additional operating notes
- The cooling mode should be selected correctly. The high ambient temperature does not mean that it is necessary to set the freezing to the maximum possible power.
- Placing containers of hot food in the refrigerator can lead to malfunction of the temperature sensor. If it is also open, then actively evaporating moisture will lead to the formation of ice. Often, this becomes the simplest cause of ice.
Allow hot food to cool before refrigerating.
- Do not overload the refrigerator with food. This may result in compressor overload. Extreme mode of operation will lead to its failure.
Filling the refrigerator too tight may overload the compressor
