Improper freezing is a common problem faced by refrigeration equipment owners. This happens both with modern know frost models and with old domestic designs. If the freezer in the refrigerator does not work, the reason may be due to improper operation or breakdown of internal elements. This situation requires a quick response and timely repair.
The freezer in the refrigerator is not freezing
What should you pay attention to first?
Perhaps the freezer is not broken, but the reason for inactivity is due to improper use of the device. The thermostat needs to be inspected. If the thermostat numbers are between three and four, it means it is working correctly. Food will freeze and the motor will work properly. The temperature in the cell will be about 15-20 degrees below zero. If you accidentally hook the regulator, no cold will be produced, and the numbers on the device will drop to a minimum.
Another reason is that the freezer has not been defrosted for a long time, and a lot of ice has accumulated there. Therefore, the seal does not fit tightly, and warm air gets inside. Every time the motor turns off, the ice begins to melt and water drips down. To fix this problem, you need to defrost the freezer and check the seal.
If the temperature in the chamber is low and there is not much ice, but the freezer still does not work, it means that some part has broken.
Signs and causes of malfunctions
When there is no cooling, but there is sanctification - what is the cause of this malfunction?
Basically, if there is no cooling in the refrigeration chamber, then this can be observed by noticeable signs on different components of the device. The main, so to speak, “symptoms” of problems are:
- The temperature in the refrigeration section is too high.
- The compressor runs endlessly or gets very hot.
Such problems can arise for many reasons, such as improper installation of the device or a compressor failure. Often there is no cooling in the very top part of the refrigerator compartment. Since in modern refrigerated cabinets the freezer is most often located at the bottom, and the upper part is the main one, in other words, refrigeration with a temperature of 2 to 8 degrees Celsius.
Failures due to which there is no cooling of a certain chamber are quite serious, since it is almost impossible to cope with them yourself and without the necessary tools. If you're lucky, simply defrosting the refrigerator and then starting it again will be enough, but such luck is very rare, so you often have to call a specialist for help in this matter.
The compressor hums, but the refrigerator does not freeze
If the engine stops pumping up the required pressure, you can hear the device humming and making strange sounds - hums and clicks that are not typical for a refrigerator. The compressor needs to be replaced; this procedure cannot be done on your own; you need to call a specialist. The cause of failure may also be overheating of the system due to prolonged use.
Lighting works but no cooling
A situation often arises in which the refrigerator functions externally (the light is on, the compressor is running), but there is no freezing. Such a breakdown can happen to any device (of various brands). Often the problem occurs after defrosting the refrigerator. The reason may lie in freon leaks, as a result of which the compressor does not cool down, but heats up. In this case, you need to check the operation of the element.
Why might the freezer stop freezing?
There are many parts that affect the operation of the freezer. Among them:
- The motor, which is directly responsible for the operation of the freezer. If it turns on, runs for a few seconds and then turns off immediately, this means that the motor-compressor is broken. There are two reasons for this malfunction. The first is that the refrigerator is many years old and the motor has never been replaced. The second is a high load on the motor (we set the thermostat to the minimum temperature on a hot summer day). The compressor needs to be replaced. It will cost about 2000 rubles.
Freezer motor - If the refrigerator has electromechanical control, the thermostat is broken.
It performs the same function as the air sensor. You need to buy a new thermostat. The asking price is about 2000 rubles. Thermostat - The freezer works, but does not freeze well. This problem often affects refrigerators of no-frost models that operate without frost. The switch valve has failed. It is necessary to switch the temperature between the refrigerator and freezer. The valve switched and stopped at the refrigerator, therefore the temperature in the freezer will be equal to the temperature in the refrigerator. In this case, you will have to replace the switch, which costs about 2,500 rubles.
This is what the switch valve looks like - The freezer started to freeze slightly, and then stopped freezing at all. The frost in the chamber is maintained by a gas called freon. Most likely it has leaked. It is necessary to charge the freezer with freon. You also need to find the place where it leaked from and patch it up. Fixing such a breakdown will cost 3,000 rubles.
Freon is sold in such containers
The motor runs, but rests for a very long time. If the refrigerator has an electronic control unit, then there is a problem with the air sensor. It is necessary to transmit information to the control unit that the temperature in the freezer is rising, but it does not start the motor. The air sensor needs to be replaced. It costs about 2000 rubles.
- Rust begins to accumulate in the freezer. This can cause Freon to evaporate as rust can create holes. If the drainage system is broken, water will constantly accumulate inside. Over time, this will lead to rust. It corrodes the plastic, and holes appear on it through which freon evaporates. It is necessary to wipe up the water in a timely manner. If a breakdown has already occurred, get rid of the rust, seal the holes and fill the freezer with freon. About 3000 rubles.
Accumulation of water
- You defrosted the unit using artificial heat sources (for example, put a container of boiling water in it). Or they removed the ice with their hands or improvised means. After this defrosting, the freezer stopped working: apparently, you damaged the plastic and the freon leaked out. You cannot help the freezer to thaw. Everything should happen naturally. Similar methods to speed up defrosting worked only on older models of refrigerators. New ones are equipped with parts whose operation 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 cost of repairs is about 3,000 thousand rubles.
- No-frost refrigerators have a fuse, defroster and timer that are responsible for defrosting. If they break, the freezer stops working. Find the broken part and replace it. Repairs cost from 5,000 to 8,000 rubles, depending on the type of broken part.
Fuse.
The prices indicated are approximate. They include the cost of the broken part, as well as the work of the technician. If you decide to replace it yourself, the cost of repairs will be approximately half as much.
Be careful when making repairs yourself. It is necessary to install only those parts that are identical to the old ones. For example, if you installed the wrong thermostat, the motor will break.
The craftsmen are well versed in various breakdowns and provide a guarantee for their work. Therefore, calling a specialist will be easier and, possibly, cheaper.
The freezer in a two-compressor refrigerator does not freeze
Dual-compressor equipment allows you to control the temperature in the chambers independently of each other through separate evaporators and control panels. Therefore, the refrigerator compartment works normally even when the freezer compartment is not freezing. The problem is noticed by thawed food or a puddle on the floor.
Is a freezer failure always a breakdown? More often than not, yes, but there is a situation where the owners “helped” the equipment.
What to check yourself
Some models of refrigerators with two compressors are designed to turn off the freezer compartment. Check to see if you turned off the freezer accidentally or on purpose and then forgot to turn it on. If the freezer is off, turn it on. Did you check and the camera is on? This means the cause is a malfunction.
Possible breakdowns of two-compressor models
Here are the freezer malfunctions that our specialists most often fix when the compartment does not freeze.
Freezer motor
The motor is responsible for circulating the refrigerant in the system. The main reasons for compressor failure: due to overload, the windings (starting and/or working) are burned out or short-circuited, the motor is jammed or the wiring and motor contacts are damaged. Instead of a faulty engine, a new one is installed, the wiring and contacts are restored or changed.
From the experience of the masters! The refrigerator motor often fails due to overload. For example, in the summer, many equipment owners set the temperature to maximum cold on hot days. The motor runs too long, overheats and breaks down. We recommend not overfilling the refrigerator in such weather, and setting the temperature a little colder than usual. The motor can cope with such a load without damaging itself.
Start-up relay for freezer compressor
The start-up protection relay in the refrigerator is located on the motor and performs two functions: it helps it start and protects it from overheating. When the relay fails, the freezer motor does not turn on at all or turns on and then turns off immediately. The start-up protection relay is replaced with a new one.
Thermostat or freezer temperature sensor
The compressor is turned on by a signal from the thermostat or temperature sensor. When there is no signal, the motor-compressor does not start and the freezer compartment does not cool. Or the inclusions are very rare with long downtimes, so the freezer does not freeze, but cools like a refrigerator compartment. A faulty thermostat in electromechanical models or a temperature sensor in electronically controlled models must be replaced with a new one.
Freon leak
The refrigerant in the tubes moves through a closed system. Part of the circuit is responsible for heating the refrigerator body around the perimeter of the freezer door. This is necessary to ensure that the seal remains dry and ensures a tight seal. A leak in the heating circuit occurs due to corrosion of the steel tube. Leaks are rare elsewhere in the freezing circuit of dual-compressor refrigerators.
If there is a refrigerant leak, the freezer motor-compressor works almost non-stop, but due to a lack of freon, it cannot maintain the set temperature in the freezer compartment. When most of the freon has evaporated, the freezer compressor stops turning on.
If a leak occurs in the heating circuit, the technician cuts it off and connects the tubes directly. Then the filter-drier is changed, the tightness of all connections is checked by crimping. Next, the technician evacuates the circuit and charges it with refrigerant.
Clogged capillary line
The capillary regulates the supply of refrigerant to the evaporator at the required pressure. The oil from the compressor “burns”, and the products of its interaction with the refrigerant are deposited in the capillary tube. The resulting paraffins narrow the lumen, freon passes through the capillary with difficulty, so the freezer compartment cools poorly, although the compressor works almost without interruption.
The blockage in the CT is removed with special solutions, purged with nitrogen or pressed with oil. When the capillary is clogged in several places or there is practically no lumen, the tube is replaced with a new one.
How to protect your freezer from damage?
There are several tips for saving your freezer:
- Do not freeze food that is above room temperature. Wait until they cool down.
- Do not help the device defrost.
- Close the door tightly to prevent warm air from entering.
- Set the temperature on the thermostat correctly. Monitor it constantly.
- Watch for water accumulation inside. Get rid of it to avoid rust.
- Follow the operating instructions.
There are many reasons why your freezer won't freeze. If you are well versed in details and know where and what is located, you can make the replacement yourself. It will be more economical than calling a specialist.
Prevention
To prevent problems with the operation of the refrigerator, the following rules must be observed.
Shutdown
When turning off the device, you must first set the temperature regulator to o. And only then can you disconnect the plug from the network.
Inclusion
Do not turn on the refrigerator immediately after cleaning it. You need to give it time to stand and dry for a while. Only then can you plug it into the outlet.
Hot dishes
Do not place hot foods in the refrigerator compartment. And even more so, you can’t put any other items that have a high temperature in it. Otherwise, a conflict between warm and cold air will occur, as a result of which the device will not work well.
Chemical substances
When cleaning the refrigerator, do not use cleaning agents that are chemical solutions.
Important! It is worth remembering that the device contains microcircuits and connecting channels. They may be damaged if they come into contact with chemicals.
There are many reasons why a refrigerator may not perform its primary function well. When faced with such a problem, you first need to check how tightly the door closes, and then move on to inspecting other elements.

#1 – Incorrect installation
The operating principle of a refrigerator is not “production of cold”. It simply removes excess heat from the chamber to the outside through a heat exchanger on the rear wall. If the refrigerator is installed near a device that produces heat (radiator, stove), it will not cool properly.
The distance to the walls and position play an important role. There are several basic installation rules:
- It is not recommended to place the refrigerator in the corner;
- The distance from the heat exchanger to the wall is at least 10 cm;
- You should not hang cabinets or shelves above the refrigerator.
The distance to the walls depends on the volume of the refrigerator, power, and location of the heat exchanger. Some manufacturers have special requirements. Therefore, read the instructions so that there are no problems with operation.
Simple repair
In some cases, you can return household appliances to working condition after carrying out simple repairs yourself.
Changing light bulbs
Replacing a burnt out light bulb with a similar new one is not a difficult job for a professional. You can read the instructions in the article; it describes in detail the procedure for removing the lampshade, how to correctly unscrew the remains of the base and other nuances.
Cleaning the drainage system
During operation, contaminants appear in the drainage system of the refrigerator - small pieces of food, grease, dust. To ensure that there is no moisture under the vegetable compartment or under the bottom, it is worth cleaning the drainage tube regularly.
Replace the rubber seal
Wear of the seal occurs due to careless operation and leads to a change in the temperature regime inside the compartments. You can learn about replacing this component from the article.
Eliminating compressor rattling
Noise that occurs during operation of the refrigerator may be due to improper operation of the compressor. The technician needs to inspect the equipment and determine whether the engine is in contact with pipes and other mechanisms.
We rehang and align doors
For ease of use, modern kitchen appliances are equipped with the ability to hang the door. Such repairs will be carried out by professionals; details can be found in this article.
Checking the correct installation
The refrigerator must be placed on a hard and level surface. To ensure that the requirement is met, you can use a building level. The equipment should not wobble or be skewed to one side. In modern models, the legs are distinguished by the ability to adjust in height, so unevenness can be eliminated. More details here.
If there is a lot of ice in the freezer
Ice in the freezer may indicate that it is necessary to temporarily turn off the equipment, defrost it, and then thoroughly wash the unit. You can learn how such simple repairs are performed from this article.
No. 5 – No power supply
If your refrigerator is more than 5 years old, there may be problems with the power supply. Wiring does not last forever; it wears out over time. The main elements that ensure normal temperature in the main chamber:
- Compressor;
- Temperature sensor;
- Thermostat.
Checking the power supply to the temperature sensor is simple. First determine where it is (look in the instructions). After this, remove the housing and check the power supply with an indicator screwdriver.
To check the power supply to the compressor you do not need to disassemble anything. It is located at the bottom of the refrigerator at the back. Locate the power terminals and check the voltage with an indicator screwdriver. How to do this - watch the video:
Checking the power supply to the thermostat is more difficult. It is located on the front of the refrigerator, usually behind the temperature control. But if you don't want to look for a refrigerator, you can try to do it yourself. You need to check the power supply using the same indicator screwdriver.
No. 11 – Damage during transportation
During transportation, lifting and installation, there is a risk of damaging the copper tubes and heat exchanger. The radiator on the rear wall can be inspected visually. And copper tubes can be damaged in the compressor area.
It is also important to wait a while before turning on the refrigerator after transport. If you don't do this, there is a risk of seriously harming him. We wrote how many hours the refrigerator should stand in this article: https://vteple.xyz/pochemu-nelzja-vkljuchat-holodilnik-srazu-posle-dostavki/.
During transportation there is a risk of damaging the refrigerator body. Moisture will penetrate into the thermal insulation through the crack and saturate it. The properties of the insulating material will deteriorate, and heat will penetrate into the chamber.
Recommendations for use
It is necessary to adhere to the necessary recommendations for operating the refrigerator. The freezer needs to be defrosted regularly, especially with a drip system. But, even if the device has a No Frost system, defrosting is required, but not so often - it is enough to do it a couple of times a year. It would be a good idea to periodically inspect the chamber for frost, wipe the walls and drawers, and throw away excess food.
It is recommended to lower the temperature slightly in summer so as not to overwork the motor. If you need to freeze a lot of food (for example, for the winter), then this should be done in portions; it is extremely undesirable to load a large amount at once. Following simple recommendations will extend the life of your freezer.
