If during the operation of the refrigerating unit, you have noticed that the ice is freezing on the walls of the chamber and the coating of thermal insulation is broken, then the reason is probably the crack on the wall of the refrigerator.
To make your fridge serve for an as long time as it is possible, it is very important to keep to the rules of exploitation, as well as to pay attention to the peculiar signs of possible malfunctions. For normal and well-coordinated work of the refrigerator, the preservation of products in it and the tightness of the chamber are important. That is why the doors of the construction are equipped with a rubber seal that allows them to adhere tightly to the body.
In case of warm air penetrates into the refrigerator chamber, the operating mode of the unit changes, and the motor – compressor begins to work without stopping. This is caused by the fact that the temperature sensor constantly sends signals about temperature increases to the working module. At the same time, the module forces the motor to work to compensate for the temperature. Since warm air flows do not stop due to the occurring damage, the compressor is forced to run without stopping.
If on a back wall of the chamber, there were ice and snow growths, there was a violation of isolation of the chamber. It happens in case of a loose connection of the door. This malfunction can be corrected by adjusting the door or replacing the seal.
Cracks of plastic on the walls of the refrigerator can occur after a blow or falling off the equipment during transportation. Therefore, it is very important to fix the refrigerator correctly and reliably during transportation. Quite often the reason for the occurrence of punctures and damage to the chamber walls is the careless handling of the equipment during its defrosting. Attempting to break off the ice with a sharp object can lead to a puncture.
Sometimes, the rear wall of the chamber freezes on the outside. This indicates that the insulation has been damaged. This further leads to the penetration of moisture and its freezing. To do the repair work yourself, it is necessary to fix the damage to the outer layers of insulation. To do this, it is recommended first of all:
– disconnect the equipment from the mains;
– Use a sharp knife to remove the damp part of the insulation layer;
– put in its place the normal insulation or use the assembly foam;
– Once the foam has cured, attach the metal foil to the top.
If the cracks are formed on the internal walls of the freezer, the damage can be repaired as follows: disconnect the equipment from the power supply, wait until it has dried up, dry the fridge compartment, degrease the area with the crack carefully, then apply evenly a layer of silicone sealant, let it dry up and plug in the fridge.
In the process of repair, a complete replacement of the filter of the dryer is made. For this purpose, the old one is cut off and a new one is mounted in its place by a specialist. Such a procedure is simply necessary if the system is depressurized. Then the removal of excess moisture from the system circuit is performed using a vacuum pump.
After this work, the technician checks the system for leaks. Overpressure is applied to the system circuit, exceeding the operating values by several times. During the evacuation of the system air is pumped out from the contour and full charging of the system with the refrigerant is performed using special equipment. An accurate volume of freon, provided by the model and brand of the refrigerator, is charged into the system.
At the end of all the work, the entire refrigeration system must be checked for proper operation. If the system during the test shows all the necessary working parameters, our specialists complete the work and provide the customer with a warranty for all the repair work.
