In most models of modern refrigerators, the noise level is so low that sometimes it is very difficult to hear whether the compressor is working or “resting”. However, if the refrigerator works without stopping, all deviations from the norm are noticed by all. Moreover, in addition to the non-stop operation of the compressor, there are other signs of a malfunction - the refrigerator has stopped freezing, or vice versa, it greatly freezes. And not always these reasons are the result of insufficient care, because all owners know how to defrost a refrigerator, and usually follow the manufacturer's recommendations almost in time. Below we will examine why the refrigerator does not turn off and what can be done in such situations.

The main reasons why the refrigerator does not turn off Refrigerators are related to complex household appliances and various reasons why the refrigerator works without stopping can be many. But not all of them relate to breakdowns.. Often users themselves create conditions under which the refrigerator works without shutting down. These reasons include:.

improper installation of the refrigerator. At the same time, there is no minimum clearance between the body, wall, kitchen furniture and heating devices. Because of this, refrigeration of freon is difficult and the refrigerator rarely turns off. And the additional load on the compressor leads to its overheating and to a reduction in its resource;

cases when the regulator is set to the lowest temperature. Not always the refrigerator can cool the food in the chamber to such a temperature. Especially in the hot season. And if it can, then to maintain it requires almost round-the-clock compressor operation. Therefore, the refrigerator does not turn off for a long time. A similar situation arises when the superfrost mode is turned on for a long time;

wrong choice of the climatic class of the refrigerator. The appliance is not designed to operate in rooms with such a high temperature and the refrigerator does not turn off, trying to reach the set temperature;

irregular maintenance, during which the defrosting of the chambers and the cleaning of the drainage channels have not been performed. Due to the accumulated ice, the heat transfer of surfaces deteriorates and the refrigerator does not turn off;

loading in a refrigerator a large amount of warm products at once. Due to the need for a large amount of cold, the refrigerator works without interruption for several days until the products reach the required temperature.

In addition, often the refrigerator works without interruption due to a loose door. In this case, all the cold generated by the compressor goes out.

The most common malfunctions leading to the fact that the refrigerator rarely shuts down. It is not always possible to cope with the failure of the refrigerator systems by unscheduled defrosting or by setting a more gentle operation. Sometimes, however, breakdowns of individual nodes also occur due to which the refrigerator is constantly working. Some of them fail from normal wear and tear, and some from improper use and careless maintenance.. Let's consider the most common of the malfunctions and effective ways to restore the refrigerator.

Lost properties of rubber door seals. Through violations of the chamber’s tightness, warm air enters and, in order to reach the temperature set by the owner, the refrigerator works constantly. You can replace a worn seal. In this case, the most difficult thing is to find the original seal for your model of refrigerator;

The temperature controller or temperature sensor has broken. In such cases, the refrigerator freezes, but does not turn off. Soon a solid “fur coat” of hoarfrost or a thick layer of ice will appear. You can check the control elements of the refrigerator with the help of a tester: the contact group of the thermostat must open when the set temperature is reached. After installing a new part, the normal operation of the refrigerator will be restored;

Compressor assembly failed. Trying to set the required temperature, the refrigerator works, but does not freeze. But alas, because of a breakdown, this can not be done.. It is necessary to replace the compressor. Despite the fact that it is not difficult to remove the old and install a new unit, other operations (purging the system, injecting freon and sealing the system) require special accessories and skills in working with refrigeration equipment. Therefore, service center specialists should be invited to replace the compressor unit;

Refrigerant escaped from the system. In such cases, the compressor heats up, the refrigerator does not freeze. After all, the most important link in the process of heat extraction from products is precisely the refrigerant. Very often, for this reason, the refrigerator does not turn off after defrosting. And probably the owner due to inaccurate removal of ice mechanically damaged one of the pipelines. Such breakdowns are eliminated by the specialists of the service center, so the repair is quite complicated and laborious. It is necessary to find a leak, seal the system and download freon.

The malfunctions described above are characteristic both for refrigerators with a drip auto-defrost system, and in models with “dry” No Frost frost. But in the latter, another failure may occur - the failure of the fan, which ensures the distribution of cold air in the chambers. At the same time, the refrigerator know frost does not turn off, since the required temperature cannot be established in the chamber.

Sometimes it even happens that the refrigerator does not turn off after replacing the thermostat. At the same time, it normally (even very) cools foods. In such cases, it is necessary to verify the correct connection of the new part and its serviceability.

If you find that the refrigerator does not turn off, you must immediately find out and eliminate the cause, as long-term operation of the refrigerator without stops will ultimately lead to compressor failure and costly repairs.
