Why on the rear wall of the refrigerator freezes ice and snow

When the refrigerator is serviceable

For refrigerator system with a dropping ice formation on the inner side of the chamber - the norm, if the layer is not thicker than three millimeters and are periodically thawed.

In other cases, there is the icing on the user's fault, when violated the rules of operation:

• hot food loading;
• setting the maximum cooling temperature;
• outdoor storage of liquids;
• not completely closed the door, her frequent opening;
• contamination in the chamber, which is not washed immediately.

You can not put the dishes with the food immediately after cooking - water contained in the products evaporates rapidly and is deposited on the inner walls. Condensate freezes and this leads to icing. Soups, juices, soups, juice or water condensate recovered, if placed in the refrigerator being opened. therefore with food and liquid containers must be closed with lids or cling film.

Even in hot weather do not expose mode to the maximum. To preserve food enough temperature + 5-8 ° C. And the increased load on the compressor will lead to wear the device for the formation of snow and overrun electricity. Check the internal temperature of the refrigerating compartment by using household thermometer.

By careless closing of the door can not see how it will remain open. This would lead to overheating of the device. Indoor air is a source of condensation forming of frost coat.

Food residues may also contaminate the automatic defrosting system. Therefore, regular cleaning inside the chambers and the rules of operation will eliminate the possibility of malfunctions. If the refrigerator is used in normal mode, but the icing is still growing, it is necessary to look for the cause of failure.

malfunctions

In the refrigerator frost may occur when faults associated with a weak seal chamber, clogging the drain hose, Refrigerant loss or malfunction of electronic components.

the wear of the seal

Rubber profile according door perimeter seals the chamber, not allowing the indoor air to heat the food and the cooler wall. Seal with time and wear wrinkled. Oxidation by oxygen does friable rubber which leads to cracking. When careless use of gaps can be formed.

Wear gum entails violation temperature. To maintain the apparatus without stopping cold starts freezing cycle. Increased compressor operation supercool capacitor, so moisture is frozen does not have time to thaw and flow down the drain.

Determine the fault can be the characteristic feature - the back wall is covered with a uniform layer of ice at the bottom of frozen peas. At the same time the engine is running continuously.

Check the condition of the seal can be by visual inspection and palpation. If there is a jam, cracking, loose rubber and keeps its shape - so wear gum caused icing.

To remedy the problem, need repair dock or complete its replacement by a new one.

Contamination capillary conduit

If partial occlusion of the refrigerant tubes is disturbed movement. Contamination occurs when overheated lubricant combines with Freon circulating in the system. Oil clot interferes with the normal movement of the refrigerant pipe.

The fault is accompanied by increased motor heating, the formation of frost coat in the chamber. The temperature regime change, and the compressor is running without stopping.

To correct the damage, you need to call the master. He cleared the capillary tubes from clogging, change the engine oil and to upload new refrigerant.

freon leak

In this case, the temperature rises and the device does not cope with the cooling chamber. In models with drip defrost leakage occurs due to contact with the melt water on the metal tube. Moisture causes oxidation and corrosion. Prolonged exposure to the metal walls collapse, resulting in leakage of refrigerant. Units with an automatic thawing damaged factory space rations (joints of pipes).

Chill broken, the compressor starts to work without stopping and overheating. Another symptom of breakage - partial occurrence of ice in one of the corners inside the refrigerator. After defrosting the appliance off and ceases to freeze.

To repair techniques need soldering and sealing system of the condenser tubes, freon refill of the container. If damage has occurred in the evaporator - full replacement of parts.

Faulty thermostat

sensors, starts or stops the refrigeration cycle are set to control the temperature. Electronic control system equipped with an air thermostat which measures the temperature inside the chambers. Mechanical model controlled by a thermostat, which is located on the evaporator.

Electrical damage or marriage lead to breakage of the temperature sensor. Therefore, the refrigerator begins peremorazhivat products, and refrigeration cycle is started with short intervals. The rear wall is covered with a uniform layer of the frozen condensate within the chamber is set abnormally cold temperature. Products on the shelves are frozen and covered with ice.

You can fix this installation the working thermostat.

frozen isolation

Inside lining under refrigeration plant covered insulation material. When the factory or improper operation status condensate formed in the housing. The impregnated insulation moisture freezes and accumulates outside the snow or ice.

To restore correct operation, it is necessary to remove the damaged portion of the insulator and replace it.

Breakage of the magnetic valve

Refrigerators with a compressor equipped with a valve which regulates the cold air circulation between the compartments of the freezing and refrigerating compartments. To separately inserted thermoregulation valve opening or closing stroke of the air flow.

In case of breakage of the magnetic valve passage remains open continuously. Branch refrigerator subcooled, rear wall acquires a uniform layer of ice. Freezer, conversely, is operated at an elevated temperature. To repair the device need replacing old valves per worker.

In identifying the symptom, disconnect the unit from the mains, to get the products and during the day to defrost it with open doors. Ott removing the water, you need to turn the device on the network.

If after thawing frost or freezing appears again, and the reason is not able to resolve on their own, need help wizard.
