The device of a typical refrigerator
The compressor pumps freon (cooling agent) into the condenser assembly with its pressure. There gaseous refrigerant condenses into the liquid fraction. This process is accompanied by the release of heat, which is removed through the rear panel of the refrigerator.
The liquefied freon is fed into the system of thin tubes, after which it again takes on a gaseous state, and when it is in the evaporation unit, it boils. Evaporator and generates cold. Freon completes his circuit, returning to the compressor.
The resulting cold primarily goes to the freezer, and from it is already fed to the refrigerator - forcibly or naturally. This gives the freezer the ability to maintain a cool temperature even when some parts of the unit break down.
As soon as there is a lack of cold in the cooling compartment with a properly functioning freezer, you need to try to analyze the situation yourself.
The user actions in case of suspected malfunction of the unit should be as follows:
- establish through observation which particular chamber does not get cold;
- check if there are any heat sources near the refrigerator, for example, radiators, heaters, stoves, etc .;
- determine whether the rubber door gasket is intact, whether there are objects (pieces of food, crumbs, etc.) that prevent the door from closing tightly.
It will also be useful to examine the rear surface of the refrigerator for mechanical damage, and for all components and systems for rye and oxide.
The reasons for the lack of cold, their elimination
With proper operation of the freezer compartment, the causes of damage to the refrigerator compartment can be very different. As an ordinary temporary lack of electricity in the network, as well as a serious breakdown of the compressor, which almost always leads to its rather expensive replacement.
No. 1 - the simplest problems of the unit
Before starting the analysis of the problem, you should make sure that the unit is connected correctly to the electrical network, that wires, extension cords, outlets, and that the power supply to the room is working properly.
One of the culprits is a loose closing of the camera door due to user oversight. There is a constant intake of warm air from the room inside.
Cold may be absent due to the long period of operation of the refrigerator without scheduled defrosts. It is necessary to turn off the unit, carefully defrost it and turn it on again in a day.
There are situations when the freezer compartment is filled with products too tightly, so that there is practically no free space. According to the rules of operation, this is undesirable, since there should still be a space for air circulation.
When the products for freezing lie close to each other and tightly packed, all the compressor power is spent on freezing its huge volume, and there is not enough cold for the remaining compartments.
The refrigerator itself may not be installed correctly - right next to the wall, when the heat cannot be completely removed, or close to heaters - temperature detectors get confused. They give the compressor signals to increase its power, but cooling in the refrigerator does not occur, because it turns into heat along the way.
This malfunction mainly occurs if the freezer box is installed inside the refrigerator. This problem is eliminated by a complete long-term defrosting of the entire unit, installing it away from heat sources, switching on in standard rather than enhanced mode.
No. 2 - breakdowns in conductive systems
In order to understand the causes of more complex breakdowns, you need to know how it works and how the refrigerator works. Only then will the origin of the problem be understood. As a result, the correct ways to solve the problem can be found.
Capillary system. The culprit in the capillary system may be the culprit of the breakdown due to the ingress of foreign substances into the pipeline - moisture, oils, litter from the filter that has become unusable, and so on.
Due to clogging, the cooler does not reach the end - everything is in order with freezing, even ice will form there. And the products in the second chamber are not cooled - it is warm in this compartment.
Signs of clogging of capillaries can be confused with a breakdown of a different nature - a malfunction of the evaporator. To accurately determine the cause of the problem, analyze the temperature of the discharge system in the section "condenser-compressor". If the heating there is insignificant or partial, and the cooling is quick, then the cause is a blockage in the capillaries.
However, there is an opportunity to correct the situation on your own: if the congestion is simple, then a light tapping on the pipeline will move the cork from its place and the path for freon will be freed.
If tapping does not help, you need to contact a master who professionally cleans the tubes, installs a new clean filter, replaces the freon, and removes unnecessary air from the evaporator.
Drainage system. The drainage system in refrigerators with a weeping wall may become clogged. If it is not cleaned for a long time, congestion may appear in it that does not completely allow melt water to pass through, it accumulates at the bottom of the chamber and flows out.
Over time, plastic cracks, and water flows into the gaps and oxidizes the metal parts of the device, corrosion corrodes them, and the refrigerant starts to leak out. They clean the drainage system using a regular pharmacy rubber bulb. It is filled with hot water and poured into the channel with a sharp movement under the greatest pressure.
If necessary, this is repeated several times until the system is completely cleaned. Dirty drained water from a special tray should be removed after the procedure.
Another tool for cleaning the drainage system is a bicycle / car hand pump. If these devices are not available, or the blockage is stuck very firmly, a long wire / wire will help.
The tip of the wire is bent into a loop and inserted into the drain hole with twisting movements, while feeding it back and forth. The duration of the procedure is about three minutes. You can combine two methods - wire cleaning with a spill of water.
You can check the result of efforts by testing the system. Some water is poured into the drainage tube and the drain rate is noticed in a natural way. If it does not go away, the cleaning procedure is repeated.
No. 3 - problems with automation, electronics
A temperature detector is installed in the refrigerator. It can be damaged by substances and liquids that have fallen from food, or have a factory defect.
If the sensor shows incorrect information, refrigerator compressor It operates at high power and quickly fails during such operation. The solution is to replace the detector with a new serviceable module, which can only be done by a specialist.
Other built-in sensors and electronic control systems can also malfunction, and mechanical buttons break and become clogged. Unnaturally long interruptions in the operation of the compressor will tell about such problems, when the electronics incorrectly show the air temperature in the refrigerator compartment and sets the wrong mode of operation.
It is recommended to inspect all electronic and automatic elements for serviceability, in case of failure, replace unusable parts. It is better to turn to a qualified master for this, unless the user himself has the necessary knowledge and skills in this area.
If the refrigeration unit is equipped with one compressor and NoFrost system, then the problem may be caused by a jam in the camera cooling regulator. If this occurs in maximum cold mode, the compressor cannot handle the high load. The solution is to replace the valve.
No. 4 - refrigerant leak from the system
Freon can enter the room air through micro-holes in the tube system. These holes occur during improper use.
For example, in a situation where the refrigerator has not been defrosted for too long and a thick layer of ice has grown on the tubes, and there is little time for defrosting.
The less freon left in the refrigeration unit, the less cold will be generated, and the compressor will receive an additional large load and wear out faster. In this case, it is recommended to immediately seal the system and charge refrigerant. This requires special equipment and knowledge.
No. 5 - malfunction of one of the compressors
In refrigerators equipped with two compressors, only one of them breaks down. Then the freezer compartment works properly, and the refrigeration compartment does not receive its portion of cold. A sign of this is the start of the compressor and an instant stop or its complete inoperability.
In almost all cases, this problem is resolved by replacing the failed module.
No. 6 - problems with sealing gum
The rubber seal on the door of the refrigerator compartment may be damaged, peeled off, and dried. The drying of the rubber element is mainly due to the long idle time of the unit in a state of inactivity.
Due to a malfunction of the seal, warm air from the room is able to penetrate the chamber and increase its internal temperature. The compressor amplifies its power, pumping more and more cold, but this does not save the situation, but only wears it out.
For a dried rubber pad it is possible to try to restore the lost elasticity by treating with boiling water:
- they take it off;
- soaked in boiling water;
- then set in place.
If the gap is formed in a single copy and is small, you can simply glue the seal in this place with silicone, instant glue. As a temporary option before acquiring and installing new gum You can fill the resulting gaps with cardboard inserts.
Sometimes the situation is corrected by hinging the door in the opposite direction, but here you need to consider the location of the refrigerator in the room, because there must be free space to open the door.
It happens that the door does not close tightly, not because of problems with the seal, but from the arising of the fragility of its fastening, when the fasteners are loosened. Then you need to tighten the hinges, screws, and the problem will be eliminated.
No. 7 - mechanical and chemical damage
Mechanical damages may appear on the case of the refrigerator - cracks, holes in the back wall.Usually they form after improper transportation, operation.
This is fraught with the penetration of warm air from the room into the refrigerator. The temperature inside cannot reach the desired level, compressor runs non-stopbut this does not fix the problem.
If the hole is small, you can try to fix it yourself. To do this, the refrigerator is turned off, completely thawed and dried, the damaged area is carefully cut off, filled with new insulation or foam with its further foil coating.
An area with a risk of cracking is located near all fasteners - too tight tension of nuts can subsequently lead to breaks in these places. Repair gaps in the same way - with the help of sealing with a sealant.
No. 8 - oxidation and rust on the tubes
Before diagnosing the oxidation of the metal tubes of a refrigerator, you should know that green layers are not related to corrosion. This is a consequence of the interaction of solder flux with oxygen in the room. Such a plaque is prohibited.
The danger of tube corrosion is that over time it completely corrodes their walls, through the formed holes the refrigerant starts to leak into the air, the compressor operates at maximum power.
Contrary to this, the cold does not enter the refrigerator compartment, because it is only enough for servicing the freezer. If measures are not taken in time and traces of corrosion are not eliminated, the compressor will fail, and then unit repair will be expensive.
Rust treatment is effective against rust stains with a rust converter, which can be found in special stores, or with ordinary household vinegar (9%). Before processing, it is recommended that they be tested in small quantities in one small area.
If no surprises have arisen, the product is used on all rusted areas, left for some time for the reaction of surface oxidation with air, polished with a soft cloth.
