Why the freezer does not freeze and what to do

There are many breakdowns that can cause a stop. freezer operation. Users drop into this part of the refrigerator less often, because it is not always possible to notice a breakdown on time. Let's see why freezer or the freezer chest stopped freezing.

What should I pay attention to first of all?

The freezer may not be broken, and the reason for inaction is the improper use of the device. It is necessary to inspect the thermostat. If the thermostat numbers between the three and four, then it works correctly. Products will freeze and the motor will work properly. The cell will have about 15-20 degrees of frost. If you accidentally hook the regulator, cold will not be generated, and the numbers on the device will drop to a minimum.

Another reason is that the freezer has not been thawed for a long time, and a lot of ice has accumulated there. Therefore, the sealant is loose and warm air enters. Each time the motor turns off, the ice begins to melt, and water drips down. To fix this problem, you need defrost the freezer and check the seal.

If the temperature in the chamber is low and there is little ice, but the freezer still does not work, then some part has broken.

Why could the freezer stop freezing?

There are many parts that affect the operation of the freezer. Among them:

1. A motor that is directly responsible for the operation of the freezer. If it turns on, it works for several seconds and immediately turns off, this means that the motor-compressor is broken. There are two reasons for this malfunction. The first is for the refrigerator for many years, and the engine has never been replaced. The second is a high load on the motor (set the minimum temperature on a thermostat on a hot summer day). It is necessary to replace the compressor. It will cost about 2000 rubles.

2. The motor works, but rests for a very long time. If the refrigerator is equipped with an electronic control unit, then there are problems with the air sensor. It is necessary to transmit information to the control unit that the temperature in the freezer rises, but that the engine does not start. It is necessary to replace the air sensor. It costs about 2000 rubles.
3. If the refrigerator is electromechanically controlled, the thermostat has broken. It performs the same function as the air sensor. You need to buy a new thermostat. The issue price is about 2000 rubles.

4. The freezer works, but it freezes badly. This problem often concerns the refrigerators of the know-frost models that work without hoarfrost. The switching valve is out of order. It is necessary to switch the temperature between the refrigerator and the freezer. The valve switched and stopped on the refrigerator, because in the freezer there will be a temperature equal to the temperature in the refrigerator. In this case, you will have to replace the switch, the cost of which is about 2500 rubles.

5. The freezer began to freeze slightly, and then stopped freezing altogether. The frost in the chamber is maintained thanks to a gas called freon. Most likely, there was a leak. It is necessary to fill the freezer with freon. It is also necessary to find the place from where it flowed out and patch it. The elimination of such a breakdown will cost 3000 rubles.

6. Rust begins to accumulate in the freezer. This can cause freon to evaporate, as rust can make holes.If the drainage system is broken, water will constantly accumulate inside. Over time, this will lead to rust. It corrodes plastic, and holes appear on it through which freon evaporates. Wipe up water in a timely manner. If a breakdown has already occurred, get rid of rust, seal holes and fill the freezer with freon. About 3000 rubles.

Water accumulation

1. You thawed the unit using artificial heat sources (for example, put a container of boiling water in it). Or they removed ice with hands or improvised means. After this defrosting, the freezer stopped working: apparently, you damaged the plastic and freon leaked. Do not help the thaw freezer. Everything should happen naturally. Similar methods to accelerate thawing worked only on older models of refrigerators. New parts are installed, the operation of which does not provide for such defrosting methods. It is necessary to find the place that was damaged, patch it, and also fill the freezer with cooling gas. The repair price is about 3000 thousand rubles.
2. Know-frost refrigerators have a fuse, defroster and timer, which are responsible for defrosting. If they break, the freezer stops working. Find a broken part and replace it. Repair costs from 5,000 to 8,000 rubles, depending on the type of broken part.

The indicated prices are approximate. They include the cost of the broken part, as well as the work of the master. If you decide to do the replacement yourself, the repair price will be about half as low.

Be careful when repairing yourself. Only install parts that are identical to the old ones. For example, if you set the wrong thermostat, the motor will break.

Masters are well versed in various breakdowns and give a guarantee on their work. Therefore, calling a specialist will be easier and, possibly, cheaper.

How to protect the freezer from breakage?

There are some tips for saving your freezer:

1. Do not freeze foods with temperatures above room temperature. Wait for them to cool.
2. Do not help the device defrost.
3. Close the door tightly so that warm air does not enter.
4. Set the temperature correctly on the thermostat. Constantly monitor it.
5. Watch for accumulation of water inside. Dispose of it to avoid rust.
6. Follow the rules of use.

There are many reasons why a freezer does not freeze. If you are well versed in the details and know where and what is located, you can make the replacement yourself. This will be more economical than calling a wizard.
