Repair of the refrigerator the hands

It is desirable to trust repair of the refrigerator in case of detection of any malfunctions to professional master, but a number of malfunctions can be revealed and even to repair independently. How to execute repair of the refrigerator the hands, will tell Infoadvisor.net.

The sequence of actions for detection of malfunctions is considered for refrigerators compressor without NoFrost system.

The refrigerator - one of the major electrical household appliances in the house of each of us therefore even daily "idle time" of the refrigerator can turn back an array of problems. The list of the most widespread possible problems includes the following:

• the refrigerator does not turn on
• the refrigerator works, but does not "freeze"
• the refrigerator poorly "freezes"
• the refrigerator strongly "freezes"

For a start, it is necessary to remember the principle of operation of the refrigerator. The refrigerator consists of the compressor, the condenser, the evaporator connected by tubes. On tight system of pipes so-called coolant, i.e. gas which possesses the low temperature of boiling and evaporation circulates: at expansion it absorbs heat from environment, and at the subsequent compression – gives it due to condensation. In the majority of household refrigerators as coolant freona act, in industrial refrigerating units ammonia is often used.

Coolant in a gaseous state arrives from the evaporator on the motor compressor where it contracts, and after moves in the condenser. In the condenser the coolant heated as a result of compression cools down and passes into a liquid state.

Liquid coolant under pressure gets to kappilyarny tubes, and then to an internal cavity of the evaporator therefore after expansion and transition to a gaseous state absorbs heat from evaporator walls. The internal space of a chamber of the refrigerator thus is cooled.

The cycle will be repeated until temperature sensors in the refrigerator do not record the necessary temperature (it is established on a temperature regulator). After that the temperature regulator disconnects an electric chain and the compressor is switched off (for economy of an expense of the electric power). When temperature in the refrigerator due to various external influences increases, the cycle is repeated again.

The refrigerator does not turn on

For correct operation of the refrigerator the feeding tension has to be in limits of 200-240 V, otherwise will work safety mechanisms of this electric device. Therefore before looking for malfunction, it is necessary to check tension level in the power supply network. Check is carried out by the special measuring device the voltmeter or a universal multimeter (tester). Having installed measuring probes to contacts of the electric socket (to hold only the isolated sites of probes!), it is possible to learn the feeding tension in a network.

If tension in the power supply network is in limits admissible, the faulty plug fork or a faulty network cord is the possible reason of malfunctions. Replacement of these elements by the new has to solve a problem.

If tension indicator bulb burns, the cord and a fork means are serviceable, it is necessary to check a temperature regulator. It is necessary to find two wires suitable to a temperature regulator, and, having removed from plugs, to close them among themselves. If after this operation the refrigerator started working, it is enough to replace a temperature regulator for continuation of normal operation of the refrigerator.

In case the temperature regulator is serviceable, it is necessary to check the button of defrosting of the refrigerator if that is present, similarly.

If the previous measures did not help, it is necessary to check as well other elements of an electric circuit of the refrigerator. By means of an ohmmeter it is necessary "to ring out" the starting and protective relay of the refrigerator (sometimes relays are assembled in one case). At detection of break it is necessary to replace a faulty detail.

The motor compressor – the most important element of the refrigerator if it is faulty, as a rule, is required its full replacement. Repair of the refrigerator the hands in case of breakage of the compressor is impossible – correctly pick up and install the new compressor only the professional master can.

The refrigerator works, but does not "freeze"

Similar consequences are characteristic for several types of malfunctions: freon leak, violation of work of a temperature regulator, malfunction motor compressor.

At freon leak the condenser which in norm has to heat up (to 70 °C), remains cold even during the long operation of the compressor. Independently heavy to find a freon leak place – for this purpose it is necessary to merge coolant from system and under pressure to pump air in system. In a leak place the current of air will be notable. The problem will be solved by refueling of the refrigerator coolant and sealing of a place of leak – it is necessary to call the master.

At suspicion on malfunction of a temperature regulator, it needs to be replaced on obviously serviceable and to estimate result of work. A faulty temperature regulator to replace or give on adjustment.

Malfunction the motor-komressora in power to define and eliminate only to the expert.

If the refrigerator "freezes", but is weak, perhaps, the malfunction of a temperature regulator which is already described earlier takes place. Actions in this case are similar the aforesaid.

Also weak "frost" can be a consequence of depressurization of the refrigerator – sealing rubber on a door got out of a shape and elasticity. In this case in the refrigerator warm air from the outside can get that reduces compressor productivity. Leaky "rubber" should be replaced.

Violation of operation of the refrigerator when the refrigerator strongly "freezes", can be caused by the wrong adjustment of a temperature regulator – to install the handle of a temperature regulator one temperature higher" enough and the problem is solved.

The described malfunctions do not cover all list possible malfunctions in operation of the refrigerator. Repair of the refrigerator the hands becomes complicated if the refrigerator is equipped with the operating chips, etc. Only the expert can give help in this case.
