The situation when the refrigerator breaks down is always unexpected and unpleasant. Especially on the eve of a big feast or in a big heat, when you need to carefully monitor the freshness of products. Often, users are faced with a different problem when the freezer works, and the refrigerator practically does not cool. How to determine the cause?

Why is the refrigerator not cooling well?

Such a breakdown is rarely immediately noticed, since the health indicator is not the indicators on the thermometer in the refrigerator, but the freezer, which continues to work well. A difference of several degrees is difficult to feel for an ordinary person, but the food in the refrigerator deteriorates literally before our eyes.

If a malfunction is detected, you need to find out as soon as possible the reason why the refrigerator does not freeze. Postponing repairs will result in complete failure, and then the owner will have to spend a lot on repairs, if at all.

Here is a list of possible reasons why the refrigerator stopped freezing:

• Poor closing of the door. It is possible that a foreign object has fallen under the rubber band of the door, which prevents the hermetic slamming of the door. Check not only its absence, but also the integrity of the protective gum. Punctures, tears or flaking contribute to the release of cold air to the outside;
• High temperature in the room. More typical for single-chamber models. If the refrigerator is near a hot battery or the room is very warm, and the freezer is set to maximum freezing, the electrical motor cannot cope with the high load. Try to choose a more gentle mode of operation. Complete defrosting for at least 10 hours will not interfere. After that, set the desired temperature again and turn on the device. Do not forget about the thermal insulation of batteries near the refrigerator.
• Another reason why the refrigerator does not cool may be damage to metal cooling elements and freon leakage. This could happen if, during defrosting, you removed the ice from the cooling grate with a knife or other metal objects. In this situation, you can not do without the help of a qualified master. But you can solve the problem without huge costs. It will be necessary to seal the damaged area of ​​the cooling element and refill the system with freon. If you don't want your refrigerator to stop freezing, never force the ice to peel off when defrosting. It is better to wait for complete thawing and then easily remove the lagging ice.

The described breakdowns are typical for both single-chamber and two-chamber refrigerators. Basically, such a failure is associated with improper operation, non-compliance with sanitary standards for use and can be independently diagnosed and prevented.

But it happens that the refrigerator does not cool, although all the norms are met and there are no visible reasons for the malfunction. In this case, you need to more carefully examine the electrical appliance and analyze its operation. Most likely, it will not be possible to repair at home without a master, but you will be able to estimate the cost and duration of the upcoming repair.

Complex technical problems

If the refrigerator began to freeze poorly, its breakdown may be associated with one of the key structural elements. Let's look at the main problems with the motor that lead to the fact that the refrigerator does not cool the air to the desired temperature - fan motor failure.

In this case, you will not hear the characteristic sound that the fan makes during operation. The breakdown occurs due to the freezing of the element and requires its mandatory replacement by a specialized master.

Since the motor does not run constantly, but turns on only periodically, in order to determine the malfunction, you need to carefully listen to the operation of the refrigerator. You can try turning off the refrigerator and completely defrost it for 10 hours. If even after defrosting and restarting the situation does not improve, a repairman should be called.

Compressor failure is another issue.

A single-chamber refrigerator has one compressor, so its breakdown is immediately visible, since the refrigerator does not cool the air either in the freezer or in the refrigerator and quickly makes itself felt with a leak. A two-chamber refrigerator, such as Indesit and other high-performance brands, has two compressors, separately for the refrigerator and freezer. If the temperature of the refrigerator compartment does not match the settings, the compressor could fail. The problem is solved by replacing the element.

Quite often the refrigerator does not cool due to blockages in the cooling system. The capillary tube through which the refrigerant circulates tends to become clogged. An experienced craftsman can easily fix the problem with special equipment.

Often the cause of a breakdown can be a refrigerant leak in the evaporative system of the refrigerator. Leaks can occur for a variety of reasons, but mostly due to system wear and tear. You can detect such a breakdown not only by checking the temperature of the refrigerator compartment, but also by rusty smudges inside the freezer compartment, if it is located below. In addition, you can see water or oil smudges under the refrigerator itself.

Special attention is paid to malfunctions of various sensors and thermostats. Since there may be several of them in different models of refrigerators, for example, Samsung, their failure entails a change in temperature, ice, snow, smudges, continuous fan operation or long pauses between engine start cycles.

In any of the above cases, you should not delay the moment of meeting with the repairman. Not everyone will be able to replace it on their own or solve the problem in any other way, and the operation of a refrigerator with a faulty element increases the load on other systems of an electrical appliance and can lead to a final failure without a chance for repair.

What to do if the refrigerator is not cold?

If you notice a significant change in temperature, you should first check:

• Clearly determine that the refrigerator is not working, but everything is in order with the freezer;
• Perhaps there are heaters next to the refrigerator. Batteries must be insulated;
• Check the integrity of the sealing gum on the door;
• Check all the buttons for adjusting modes and temperatures;
• Determine if there is ice and snow in the freezer. Try setting the freezer temperature to a higher temperature. It may happen that the motor simply cannot cope with the load when the refrigerator does not cool the air, and the freezer is operating in intensive mode;
• Inspect the refrigerator externally for rusty, oily or other smudges;
• Is there any deformation of the elements and the inner surface of the refrigerator.

Having correctly determined the nature of the breakdown, you can immediately report it to the master so that he can take with him the components necessary for replacement. A quick response will help you avoid costly and lengthy repairs.
