The refrigerator does not work, but the freezer is working: reasons

It is necessary to store food in specially designated places and on appropriate shelves.

The device and principle of operation of the refrigerator

In order to understand in more detail all types of breakdowns, you need to know the important points of the device of the freezer and the refrigerator as a whole. The main components of household refrigeration equipment are:

• compressor;
• suction tube;
• discharge tube;
• capillary tube;
• filter drier;
• cold chamber evaporator;
• freezer evaporator;
• capacitor.

The principle of operation of the equipment is as follows:

From the moment of start-up, the compressor pumps freon through the tubes. In them he cools. In this case, heat is released through the rear wall of the refrigerator body. Liquefied freon moves into thin tubes and then becomes gas again. After entering the evaporation unit, it boils.

Further, the circulation of freon is completed, and it returns to the compressor. As a result, the acquired cold is delivered initially to the freezer and then to the refrigerator. Therefore, in the event of a breakdown, cold air continues to remain in the freezer.

Store products only in sealed bags.

If you suspect a malfunction of the unit, first of all, the user should check the integrity of the sealing gum, as well as observe the flow of cold air into camera.

Reasons for the failure of the refrigerating chamber when the freezer is running

A malfunction of the refrigerator can be associated with the failure of individual elements or the entire working mechanism. Various factors can cause problems with cooling in the refrigerator chambers.

The simplest non-observance of operating requirements

Often, due to simple negligence of the user, heat can be observed to enter the refrigerator compartment. For example, with a systematically loosely closed door, warm air flows from the room into the chamber. Therefore, the device does not have enough power for proper cooling.

An open door can damage not only the compressor, but other significant parts as well.

With densely packed products, the compressor cannot evenly distribute the refrigerant throughout the chamber. Therefore, it is recommended to fill the chambers so that there is a little free space between the products.

Irregular defrosting can also cause poor performance of the refrigerator. To restore the normal flow of cold, it is necessary to completely defrost the chambers, remove the melt water from the compartments, then let the unit stand for a day. After this period, the device can be started. In the future, the work process should improve.

Refrigerators are often installed near heating devices (heating systems, artificial heaters, gas and electric stoves). Such an installation is also one of the factors in the formation of excessive warm air inside the chamber.

GOOD TO KNOW!

The presence of dampness on the sealing gum leads to their aging, as a result of which they lose their tightness and let warm air into the chamber.

Minor and major faults

The reasons for the breakdown may be hardware in nature. This is considered the most serious problem. Even the most commonplace malfunctions affect the ability of the unit to cool food. Consider what breakdowns exist at this level:

1. Plug in the capillary system. The formation of plaque, sediment and debris often provoke a congestion inside, which prevents the passage of freon. This is not the case with the freezer. On the contrary, ice forms in it.
2. Drainage problems. Crying wall refrigerators often get clogged. Such systems should be regularly cleaned. If this does not happen, the formation of blockages occurs, which prevents the flow of melt water. If the system is not cleaned in time, rust will form.
3. Disruption of automation or electronics. In modern refrigerators, temperature sensors are used, which can be damaged by food residues or liquids. In this case, the sensor takes the high temperature as optimal. Other components of the automation are also capable of clogging, which affects the operation of the equipment.
4. Refrigerant leaking. This phenomenon occurs when the tube breaks down. They can wear out not only during long-term use, but also due to mechanical damage. For example, when trying to knock down ice with hard and sharp objects.
5. Compressor problem. If the refrigerator has two compressors, one of them may fail. In this case, only one freezer will work.
6. Mechanical and chemical effects. If used improperly, holes in the walls allow warm air from the room to penetrate into the refrigerating chamber. This overloads the compressor, which is unable to normalize the temperature inside the refrigerator.
7. The presence of rust and oxides. This problem often occurs when there is condensation on the back of the refrigerator. Due to bacteria actively multiplying in this environment, a green plaque appears, after which corrosion appears. These bacteria gradually eat away at the walls of the tubes. And it is forbidden to clean off such formations.

Repairing the technical equipment of the refrigerator requires a professional approach.

GOOD TO KNOW!

If there are a lot of rusty spots on the capillary tubes, it is recommended to treat them with a special converter. It can be purchased at stores that sell home appliances and radio equipment.

Diagnostics of the refrigerator when the chamber is heated

The breakdown of household appliances, of course, upsets its owners. There are no circumstances when electrical appliances are completely unnecessary. The breakdown of the refrigerator deserves special attention. You certainly can't do without it. Therefore, it is important to correctly identify its malfunction. Our editors have prepared several measures to detect the problem.

Initial inspection of household appliances

Upon arrival, the master must visually inspect the body of the refrigerator as a whole and its back wall. Initially, the presence of functioning sealants is determined, as well as the absence of cracks and dents. Such defects primarily affect the performance of the equipment. The electricity supply to the compressor must be assessed. For this, the power cable is ringed.

Refrigerator repairs can be carried out directly at home if the breakdown is not serious.

Checking by means of special equipment

The performance of the refrigerator is determined by professionals using a special mechanical device. Such equipment helps to accurately identify the place of failure, which further facilitates the repair procedure. Consider which tools are involved in testing household appliances:

1. Digital thermometer. Helps to automatically determine the temperature inside each chamber. Performs diagnostics in minutes.
2. A digital tester helps to determine the degree of resistance of the compressor winding, defrost heaters and thermal relays.
3. Vacuum pump. Suitable for refrigerator overhaul. Purges and cleans the pipes of the refrigeration unit. After that, the latter is again charged with refrigerant.

In addition to professional tools, you need to have on hand some inventory that will come in handy in case of disassembly.

What to do if a breakage problem is found

Of course, if the refrigerator is dear to you, you need to fix this breakdown. The repair method depends directly on the malfunction that has occurred. Consider below exactly what problems can be found.

The seal on the refrigerator doors is damaged or the thermostat is faulty

The only way out in case of damage to the sealed rubber bands is to completely replace them. Do not try to glue or apply an extra coat of sealant on top. Such manipulations will be useless.

The refrigerator must be unloaded and cleaned before repairs.

When the problem with warm air in the chambers of the equipment arose precisely because of the thermostat, it is easier to replace it than to repair it. Inside this mechanism there is a miniature circuit, which not every craftsman can solder.

Refrigerator motor overheated

As a rule, all the details in technology are interconnected, therefore, in the event of a thermostat malfunctioning, overheating of the main compressor may occur. This is due to the fact that the sensor is giving the wrong command to the motor. Because of this, it constantly operates at full capacity. Non-stop operation leads to overheating.

Broken fan or compressor

A faulty fan can be identified by an unusual sound. During operation, the device begins to knock or create vibrating sounds. Correct this problem by replacing the fan.

In the event of a compressor breakdown, the loss of cold in the chambers can be carried out, both completely and partially. A strong knocking and grinding noise during the operation of the unit are the main signs of a motor malfunction. In this case, it is impractical to restore the old compressor. It is more practical and reliable to install a new one. Of course, first of all, you need to decide on the model of equipment and entrust the work to specialists from the service.

Clogged filter drier or capillary system

One of the main causes of air overheating in refrigerator chambers is a blockage in the filter drier. Although it has a small size, it plays a rather significant role in the normal operation of the refrigerator. In this case, it will be necessary to replace the filter drier by cutting off the old one and installing a new one. Previously, with the help of a vacuum pump, all moisture is removed from the system.

In the event of a clogged capillary tube, problems in the operation of the refrigerator begin to appear immediately. These problems are quite dangerous for the equipment in general. To clear the blockage, it is necessary to warm up the entire capillary tube system. Before the procedure, it should be dismantled. After warming up, the system is purged with nitrogen. Therefore, in order to properly carry out the connection and pumping of freon in the future, it is better to entrust the work to a specialist.

GOOD TO KNOW!

Cleansing the capillary system may require up to 20 treatments with liquid nitrogen. So be sure to be patient when doing the work yourself.

Refrigerant leak or defrost valve problem

Freon leakage occurs most often through the fault of the owner of the refrigeration equipment. This could be due to improper use. Less commonly, the cause is a factory defect. When there is a shortage of refrigerant, heat accumulates in the refrigerating chamber, since the compressor cannot cope with cooling with the available volume of freon.

If there is frost on the back inner wall of the refrigerator, it's time to think about why it doesn't thaw. Damage can be caused by the thermostat, or the user incorrectly sets the operating mode of the equipment. In this case, it is the defrost mechanism that suffers. In the best case, you will have to adjust the operation of the valve, or, alternatively, replace it completely.

Burned out heating element near the refrigerator with the No Frost system

What can be seen when the heating element burns out? First of all, this is ice on the walls of the freezer compartment and, of course, the presence of heat in the refrigerator compartment. Solving the problem with your own hands, you need to choose the right type of heater and its configuration. It is better, after all, to entrust this matter to a specialist. If the device is selected correctly, it will be easy to install.

Recommendations for the operation of refrigerators

The further operability of the equipment depends on how correctly household appliances are used. Consider the basic rules that are not recommended to be violated.

1. Refrigeration equipment must be transported and carried only in a standing position or on its side, taking into account the placement of the condenser tube.
2. The refrigerator must be installed in isolation from heaters and batteries. The optimum temperature for equipment operation is not higher than +27 degrees.
3. Timely cleaning, removal of spoiled, decaying products. They settle on the walls, penetrate into the chambers, causing blockage of the channels for the refrigerant outlet.
4. The distribution of food in the refrigerator compartment and freezer must be even.
5. Elimination of unpleasant odors, which are the result of long and improper storage of products.

In most cases, subject to the basic requirements for the use of household appliances, the owner manages to avoid the problems of heat generation in the refrigerator compartment.
