Not working refrigerator and freezer works: Causes

Store products must be in designated areas and on the respective shelves.

The apparatus and the principle of operation of the refrigerator

To thoroughly investigate all varieties of damage, it is necessary to know the important points of the freezer and the refrigerator unit as a whole. The main components of domestic refrigeration equipment are:

• compressor;
• suction tube;
• delivery pipe;
• capillary tube;
• Filter-dryer;
• cold evaporator chamber;
• freezing compartment evaporator;
• capacitor.

The principle of operation of the equipment is as follows:

Compressor since the start of injection produces refrigerant through the tubes. In them it is cooled. Thus there is a heat through the rear wall of the refrigerator body. Liquified Freon is moved into thin tubes, and then again becomes a gas. After entering the evaporator unit boils.

Further refrigerant cycle is terminated and it is returned to the compressor. As a result, acquired cold initially supplied in the freezer, and then cooling. Therefore, in the event of a breakdown in the freezer continues to remain cold air.

Store products should be only in sealed packages.

If you suspect a malfunction occurs, the machine in the first place, the user must check the integrity of the seal gum, as well as to observe the flow of cold air camera.

The reasons for the failure of the cooling chamber during the operation of the freezer

Malfunction of the refrigerator can be associated with the failure of individual elements or all of the operating mechanism. Reasons for problems with cooling in the refrigerator chambers may be various factors.

The simplest non-compliance manual

Often, due to the simple user negligence, the heat input into the cooling chamber can be observed. For example, when the door is ajar systematically occurs delivery of warm air from the room inside the chamber. Therefore, the device does not have enough power for full cooling.

Due to the open door may suffer not only the compressor, but other important parts.

In densely laid products, the compressor can not uniformly distribute the refrigerant chamber. Therefore, it is recommended to fill the chamber so that between the products had little free space.

Irregular defrosting can also cause poor performance of the refrigerator. To restore the normal flow of cold thaw completely chamber, remove the melted water from the compartments, and then to allow the unit to stand day. After this period, the device can be started. In the following, the working process should be adjusted.

Often refrigerators installed near the heaters (heating systems, artificial heaters, gas and electric stoves). Such an installation is also a factor in the formation of excessive hot air inside the chamber.

Minor and major faults

The causes of failure can be worn by the character of the hardware. It is considered the most serious problem. Even the most trivial faults affect the unit's ability to cool the products. Consider what damage there at this level:

1. Cork in the capillary system. The formation of plaque, sludge and debris often provoke within the congestion that prevents the passage of refrigerant. In the case of freezer is not the case. In it, on the contrary, frost is formed.
2. Problems of the drainage system. Refrigerators, equipped with a weeping wall, often clogged. Such systems should be regularly cleaned. If this does not happen, there is a blockage that prevent runoff of melt water. If time does not perform clearing system, there is rust.
3. Violation of automation and electronics. In modern refrigerators type temperature sensors are used, which can be damaged or food remnants fluids. Wherein the sensor receives heat for optimal. Other components of the automation is also capable of clogging, thus affecting the operation of the equipment.
4. refrigerant leakage. This phenomenon occurs when there is a breakdown of tubes. They can wear not only for long-term operation, but also due to mechanical damage. For example, when you try to bring down the frost hard and sharp objects.
5. compressor problem. If in the refrigerator two compressors are installed, one of them may fail. In such a case will only work one freezer.
6. Mechanical and chemical influences. Holes in the walls due to improper operation allow the warm air from the room to get inside the refrigerator compartment. This causes an overload of the compressor, which is not able to normalize the temperature inside the refrigerator.
7. Rust and oxides. This problem often arises when the condensate present on the rear wall of the refrigerator. Due to actively reproduce in this environment, bacteria, plaque appears green, and then emerges corrosion. These bacteria gradually corrode tubing wall. And clean off such education is prohibited.

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

Diagnosis of the refrigerator when the chamber is heated

Breakdown of household appliances, of course, frustrating their owners. There are no circumstances where electrical appliances are not needed. Special attention is given failure of the refrigerator. Without it certainly can not be avoided. Therefore, it is important to determine its failure properly. Our editorial staff has prepared several events that allow to detect the problem.

Initial inspection of home appliances

Upon arrival, the master must visually inspect the refrigerator body as a whole and its back wall. Initially determined by the presence of functioning sealants, as well as cracks and dents. Such defects in the first place affect the equipment performance. Be sure to estimated electricity supply to the compressor. For this prozvanivatsya supply cable.

Refrigerator repair can be carried out directly at home, if not serious damage.

Checking through special equipment

The efficiency of the refrigerator is determined by professionals using special mechanical device. Such equipment helps pinpoint the location of breakage, which further facilitates the repair procedure. Consider what tools are involved in the testing of household appliances:

1. Digital thermometer. It helps to automatically determine the temperature level within each chamber. It makes a diagnosis in minutes.
2. A digital tester helps to determine the extent of the compressor winding resistance, defrost heaters and thermal relay.
3. Vacuum pump. Suitable in case of major repair of the refrigerator. Performs purging and cleaning the refrigeration unit pipes. After that, the latter again charged with refrigerant.

In addition to professional tools, you need to have on hand some tools that will be useful in the case of disassembly.

What to do if a problem is detected failure

Of course, if you love the fridge, it is necessary to correct the damage. A method of repair depends directly on the fault occurred. Consider the following, what problems can be found.

Deteriorated gasket on the refrigerator doors or defective thermostat

The only way out in case of damage of sealed gum - it is their complete replacement. Do not attempt to glue or put additional sealant layer above. Such manipulations will be useless.

Before the repair of refrigerators must be unloaded and cleaned.

When the problem with the warm air in the chambers of the equipment originated because of the thermostat, it is easier to replace than repair. Within this mechanism is miniature circuit soldering that the strength is not each master.

Overheated refrigerator motor

Generally, all items are interconnected in the art, however, in case of incapacitation thermostat may cause overheating of the main compressor. This is due to the fact that the sensor gives an incorrect command the motor. Because of this, he is constantly working at full capacity. Operation without stops leads to overheating.

Broken fan or compressor

Fan failure can be identified by the unaccustomed sound. The appliance starts to knock or create oscillation sounds. Correct this problem by replacing the fan.

When the compressor is cold break loss in the chambers can be made as fully or partially. Loud knock and rattle during operation - these are the main features of the engine malfunction. In this case, restore the old compressor inappropriate. More practical and safer to set a new one. Of course, you must first decide on the model and equipment to entrust the work of specialists from the service.

Contamination in the filter-dryer or in the capillary system

One of the main causes of air overheating in the refrigerator chambers - a blockage in the filter-drier. Though he has a small amount, but it plays an important role in the normal operation of the refrigerator. In this case, the need to replace the filter-drier by the cutoff of the old and installing the new one. Previously, using a vacuum pump, all the moisture is removed from the system.

In case of blockage of the capillary tube, problems in the refrigerator begin to appear immediately. These problems are quite dangerous for the whole equipment. To remove the obstruction, it is necessary to heat the entire capillary system. it must be removed before the procedure. After warming up, the system is purged with nitrogen. Therefore, to continue to properly carry out the connection and download freon, it is better to entrust the work of a specialist.

refrigerant leak or a problem with the valve defrost

Freon leakage occurs most often due to the fault of the owner of refrigeration equipment. This may be due to improper operation. Less commonly, the cause becomes the factory marriage. When there is a refrigerant shortage, heat accumulation occurs in the refrigerating compartment, since the compressor does not cope with the cooling capacity available Freon.

If there is frost on the rear inner wall of the refrigerator time to think about why it can not be thawed. Damage can cause the thermostat, or a user incorrectly sets the mode of operation of the equipment. In this case, it suffers from a defrost mechanism. In the best case, it will have to organize the work of the valve, or alternatively, to replace it completely.

Blown heater in the refrigerator with No Frost system

What can you see when blown PETN? First of all, it's the icing on the walls of the freezer compartment and, of course, the presence of heat in the cooling chamber. Eliminating the problem with their hands, you need to choose the right type of heater and its configuration. It is better to entrust this matter expert. If the device is picked up correctly, it will be easy to install.

Recommendations regarding use of refrigerators

On how correctly operated household appliances, it will determine the future performance of equipment. Consider the basic rules that are not recommended to break.

1. Transportation and transfer of refrigeration equipment You must be performed only in a standing position or to the side, taking into account the placement of the condenser tube.
2. The appliance must be installed in isolation from heating appliances and batteries. The optimum temperature for operation of the equipment is not above 27 degrees.
3. Timely cleaning, removal of damaged, degradable products. They settle on the walls, get inside cells, causing clogging of channels for coolant exit.
4. Product distribution in the refrigerating compartment and the freezer should be uniform.
5. Destruction of odors, which are the result of a long and improper food storage.

In most cases, subject to the basic requirements for the use of household appliances, owner manages to avoid the problem of heat generation in the refrigerating chamber.
