How to repair the refrigerator do it yourself

Despite the fact that modern refrigerators are quite reliable and able to serve several decades, they also periodically fail. Solve problems with household appliances stands immediately. With some problems you can cope with your own, while others require the intervention of specialists.

Typical refrigerator faults and their elimination

To typical problems with which you can cope with our own belong:

• the emergence of foreign sounds and rattling;
• Insufficient or strong cooling of food;
• accumulation of water at the bottom of the unit;
• not working condition light bulb or indicator;

But to serious problems that require interference of professionals belong:

• Punching current through the casing;
• disabling the device immediately after its inclusion;
• The formation of a snowy cap on the rear wall;
• termination of the motor - compressor;
• Lack of cooling.

Increased noise, rattling, knocks

Most often, no matter how it seemed trite, the rattling of the unit causes an incorrectly adjusted suspension of the compressor casing. To solve the problem, it is sufficient to lower the suspension bolts with springs to the required level.

Also racing equipment can be caused by contacting the body of the product with pipelines. This is solved by the detection of problem places and pushing the tubes. Calculate can also relay. To resolve the problem, you should make sure that it is located correctly and according to special tags.

The refrigerator is weak or very freezing

If refrigeration equipment has become strongly or weakly frost, it will be necessary to check several indicators at once:

• Most often, the unit does not freeze due to the failure of the thermostat or if it is incorrectly configured. To set up the thermostat, just turn it with the handle in the right direction.
• The problem may be in reducing the performance of the compressor motor. In this case, it is worth calling the masters. It will check the aggregate with a special measuring device. If the Freon is out of the system, it will not be frosting. You can check the leakage of freon, if after the long operation of the compressor to its surface to touch the hand and not to feel heating. But only a qualified specialist will be able to find a leakage and re-fill the system.
• The refrigerator can stop freeze, because of the poor sealing system between the walls and the doors. When, after long-term operation, the gum loses its elasticity and fit poorly, the cold goes through the slots. You can solve the breakdown using the complete replacement of the seal.
• Heat loss can occur due to the wrong position of the doors, its loose adhering. In this case, you will need to adjust the doors and put them in your former place.
• Heat loss can also be associated with malfunction, fan, fuse or timer. Such problems most often concern aggregates with a modern NO Frost system.
• Problems may also be associated with the inclusion of the fast freezing function and the incorrect position of the thermostat. The solution is to transfer the cold supply to the correct mode and turn off the freezing or turn the thermostat knob to the correct position.

The device beats the current

Sometimes consumers encounter a problem that refrigeration equipment beats the current. It can occur both during its work and in calm state.

ATTENTION: Use the device that beats the current is life threatening. Immediately disconnect it from the network and either remove the problem independently, or call the wizard.

To independently eliminate the problem, you will need a special device - a megommeter, with which the magnitude of the insulation resistance of the electrical wiring of the refrigerator is measured. The workflow will look like this:

1. Disconnect the unit from the network and check the wires on the absence of visible defects.
2. If you have not noticed flaws on the wires, another device will be required - "Earth". Its wire is connected to the refrigerator housing, and the second wire "line" to the refrigerator wire. The "Line" wire is alternately connected to the thermostat, relay and compressor wires, and the screen will display excessive resistance.
3. After the fault location is calculated, the damaged wire will be required to replace new or thoroughly.

Motor compressor constantly works

The refrigerator can start continuously if the air temperature is constantly increased or the thermostat handle is incorrectly set. Under such conditions, the equipment will work at full power. If the thermostat is set correctly, and the unit operates at full power without a break, it means that it simply failed and must be replaced. Also, the problem in constant operation of the compressor motor can be improved in the reference of the refrigerant. It is possible to determine this can only with the help of a special device. Independently repairing equipment without having the skill and necessary consumables, it is impossible. It is worth contacting the workshop.

Thermal relay often works

The thermal relay often works for various reasons:

• increased voltage in the circuit of the electric motor;
• The relay is poorly fixed;
• Contacts Relays oxidized;
• There are faults of the start relay;
• Enroll compressor.

Important: Most often, the thermal relay often works due to increased voltage in the circuit of the electric motor. If you do not fix the problem in time, the winding will brake.

You can try to correct the breakdown if you check the voltage in the electric motor network. If it is stable, check the relay. For this, the motor is connected directly without relay. If, after the manipulations conducted, the equipment begins to work properly, it will be necessary to replace the relay.

Snow fur coat formation inside the refrigerator

Sometimes in two-chamber refrigerators on the walls, an extra moisture appears in the form of water droplets or snow coats. It may occur because of the open door for a long time, or if the sealant has lost elasticity. It may also be provoked by the fact that hot food is placed in the unit. Correction of this situation begins with checking all settings in the cooling system.

Quite often, in modern models, the fur coat on the walls appears when the internal illumination is turned off. See whether the backlight works after the door is closed, it is impossible. To check, a light bulb is burning or not, put a thin object between the equipment wall and the seal and close the door. Through the formed gap you can determine the light bulb is lit or not. If it does not burn, then repair the lighting system or replace the switch button, which comes out of the wall towards the door.

Refrigerator does not fully work

If after connecting the unit to the network, it does not make any sounds, it means that the refrigerator does not work completely. This is most often due to the lack of current in the power supply network or with the failure of the refrigerator cord. If there is current, it is enough just to replace the cord or fork.

The refrigerator works, but with a short cycle

If refrigeration equipment works, but with a short cycle, it can provoke:

• high pressure;
• The presence of air in the system;
• excess freon;
• Relay operation;
• dirty fan;
• Fatal failure.

To troubleshoot problems, you need to check whether the fan is connected correctly. If a small amount of air is present in the system or an oversupply of freon is observed, they will be needed through the valve. Do not forget to check the condenser for dust pollution. Frequent response of low pressure relay leads to a clogging of the filter or breakage of the TRV. In this case, you should simply clean the filter or replace it with a new one, check the relay settings.

On the bottom of the refrigerator is going moisture

Moisture at the bottom of the refrigerator can be gathering at the bottom of the refrigerator due to violation of the position of the tube or its clogging. Crop with a breakdown can be quite quickly, if you clean the tube, reducing water into a special receiver, with a long and flexible wire. Wire is inserted into the tube and moves along the hole to the bottom of the unit. After a few minutes of the workflow, all the garbage will be released in the receiver for water.

ATTENTION: To completely clean the tube, it is better to rinse it by the method of douching several times.

The appearance of unpleasant odor in the unit

An unpleasant smell appears in the refrigerator from its improper operation. To do this, it is not recommended to place products in it with a sharp smell without special containers, on time to wipe the walls of the instrument and monitor its purity.

If the unpleasant smell still appeared in the instrument, it is necessary to quickly get rid of it. Since it will affect all the products that are stored in it. This process may take several hours of your free time:

1. Disconnect the unit from the network and leave for a while. If ice cover was formed on the walls, it is not recommended to remove it. Since we can apply mechanical damage to the technique.
2. After the equipment is fully defined, wipes its walls with special means. Powder abrasive mixtures do not choose. Better stop the choice on helium pastes.
3. We wipe the refrigerator with a clean cloth, carry it out for 5-10 hours.
4. Turn on the unit into the socket and continue its operation.

Highlight does not work

In some models of refrigerators, light bulbs in the backlight are quite often frightened. Their replacement should not cause difficulties. It is enough just to unscrew the bolt holding the ceiling, remove it and unscrew the burnt light bulb. A new lamp is screwed into its place, the power of which should not exceed 15 W., and fasten the plastic into place.

Diagnostics of refrigerator faults

Before proceeding to repair refrigeration equipment, it is necessary to carry out its diagnosis to understand, you can cope with the breakdown on your own or you should resort to the help of specialists.

1. To diagnose equipment at home, you will need to prepare a universal tester and a screwdriver. The diagnosis begins with determining the quality of the voltage in the network. If it is 220 W, it means that everything is normal. If the voltage is less than this indicator, it may be the main reason for the exit of the household device.
2. Next, carefully study the cord and the plug of the unit for integrity. It should not be defects, it should not be heated when working.
3. Next, we look at the terminals on the compressor. It is better to do with the equipment disconnected from the network.
4. We look at the compressor, which is located in the bottom rear of the refrigerator. It should not have defects and damage. After the visual inspection, check the winding. Before inspection, you must disconnect the flexible wires. Check the integrity winding chain is needed using a tester.
5. After that, you can go to the diagnosis of small parts - the temperature sensor. To do this, the wiring is removed and disconnected with a screwdriver. Each wire is checked for a tester performance.

When you definitely call masters

All refrigeration equipment malfunctions are divided into two parts:

1. There is no cooling of the inner chamber at normal engine start. Most often, the breakdown is the main components of the equipment.
2. The unit does not turn on or turn on for a short time, and then it turns off. Here, problems are associated with a malfunction of the electrical circuit of the household appliance.

In the first case, the repair should only be engaged in highly qualified wizards, as it is possible to carry out diagnostics and repairs using special equipment and perennial skills.

But if the unit has failed the electrical mechanism, it is possible to solve the problem and on its own - after the diagnosis, identifying the causes of the breakdown and the replacement of the spare parts failed.

In conclusion, I would like to note that each unit, even from the manufacturer with a world-famous name, can stop working at what time. To repair the refrigerator, you need to figure out what is the matter, to purchase the desired part and stock free time. If you don't have any special experience in repairing household equipment, it is better to turn to the masters of your case, which will solve all the problems promptly and efficiently.
