The refrigerator does not turn on, the light is off: the causes of the malfunction

Today, mod­ern hous­es and apart­ments have a large num­ber of house­hold appli­ances, which cer­tain­ly include a refrig­er­a­tor. How­ev­er, sad­ly, some­times the high­est qual­i­ty and most famous spec­i­mens fail. Today it is not a rare case when the refrig­er­a­tor does not turn on.

Signs and causes of failure

Know­ing all the intri­ca­cies of the oper­a­tion of the refrig­er­a­tor, it can be eas­i­ly repaired with your own hands. There are a large num­ber of fac­tors due to which the refrig­er­a­tor does not turn on. These signs include the fol­low­ing:

• the light is on, the light is on, but the motor does not work, there are incom­pre­hen­si­ble clicks. This usu­al­ly indi­cates a com­pres­sor fail­ure. As a rule, the refrig­er­a­tor starts click­ing with­out turn­ing on, since the com­pres­sor is not work­ing, a replace­ment is need­ed. These clicks are emit­ted by a start-up relay respon­si­ble for the oper­a­tion of the engine. Some­times the refrig­er­a­tor turns on and then turns off.
• the light is on, the motor does not turn off. If there are no spe­cif­ic clicks, but there is a sim­i­lar­i­ty with the pre­vi­ous signs, then it is like­ly that the ther­mo­stat respon­si­ble for deter­min­ing the tem­per­a­ture lev­el in the unit has failed. The con­trol does not receive sig­nals about the high tem­per­a­ture in the cham­ber, so the refrig­er­a­tor does not work.
• motor and bulb not work­ing. This usu­al­ly indi­cates prob­lems in the mains volt­age or a faulty plug.

Sum­ming up, we can say that these signs are not always infor­ma­tive, since there is not much dif­fer­ence in these signs (the light is on or not, the motor is run­ning or not run­ning, there are clicks or they are absent). It will not be pos­si­ble to defin­i­tive­ly say why the refrig­er­a­tor does not start. In this case, you must have decent expe­ri­ence, as well as a set of tools, or call an expe­ri­enced crafts­man who can instant­ly find the real cause of the break­down.

Why does the refrigerator not turn on after defrosting?

It is nec­es­sary to defrost and wash the refrig­er­a­tor only after dis­con­nect­ing it from the mains. Despite the excel­lent insu­la­tion, wash­ing a refrig­er­a­tor that is pow­ered by a wall out­let is extreme­ly dan­ger­ous. If, after defrost­ing, the refrig­er­a­tor stops turn­ing on, first of all, you need to check that the plug is prop­er­ly insert­ed into the out­let. Not the best option to give mon­ey to the mas­ter due to sim­ple inat­ten­tion.

The real rea­sons for the break­down of the unit are as fol­lows:

• break­age of an elec­tri­cal wire;
• mal­func­tion of the plug or elec­tri­cal out­let;
• oxi­da­tion or break­age of one of the con­tacts;
• ther­mo­stat mal­func­tion;
• break­age of the tem­per­a­ture sen­sor;
• con­trol unit fail­ure.

Any of these rea­sons a pro­fes­sion­al is able to see and elim­i­nate. The refrig­er­a­tor is not a com­plex unit, but repair requires spe­cial tools and skill. In gen­er­al, when the refrig­er­a­tor stopped work­ing after defrost­ing, but you don’t have the skills and tools, it is rec­om­mend­ed to call the mas­ter.

Types of breakdowns and solutions

A more dif­fi­cult mal­func­tion is con­sid­ered to be a break­down of the motor-com­pres­sor. When the light is on when the door is opened, but the refrig­er­a­tor does not turn on, you need to lis­ten to how the ther­mo­stat works and the com­pres­sor makes noise. If clicks are heard, it is almost cer­tain that the com­pres­sor is faulty.

An equal­ly sig­nif­i­cant mal­func­tion is the break­down of the ther­mo­stat. When it caus­es a mal­func­tion in house­hold appli­ances, it is very like­ly that the gas has left the bel­lows. When there is no click when the ther­mo­stat is turned on, it is quite pos­si­ble that there is no con­tact, which means that the rea­son for not turn­ing on is a mal­func­tion of the ther­mo­stat.

In this sit­u­a­tion, you need to find 2 wires that are con­nect­ed to the ther­mo­stat, then remove each from the ter­mi­nal. Then these wires must be closed to each oth­er. This method allows you to check the health of the device. If the refrig­er­a­tor is work­ing, then you need to replace the ther­mo­stat. When this fails, the defrost but­ton (if present) can be test­ed.

With the nor­mal func­tion­ing of the defrost but­ton, you need to test oth­er parts of the refrig­er­a­tor that are pow­ered by the mains. You can do this with an ohm­me­ter. Such a test must be sub­ject­ed to a pro­tec­tive, as well as a start­ing relay. Often they are placed in the same build­ing. If it finds a break, the defec­tive ele­ment should be replaced. When no defects were found accord­ing to these points, then it is quite pos­si­ble that the rea­son is the elec­tri­cal cir­cuit of house­hold appli­ances, which can only be repaired by a pro­fes­sion­al.

The next rea­son that the refrig­er­a­tor does not turn on may be snags with the net­work. When the prob­lem lies pre­cise­ly in it, then the own­er is lucky. In order for the refrig­er­a­tor to work nor­mal­ly, a volt­age in the range from 200 to 240 V is required. If the indi­ca­tor is not in this seg­ment, then an emer­gency shut­down of house­hold appli­ances occurs. This is espe­cial­ly true for today’s refrig­er­a­tors, as they some­times do not turn on even with small changes.

Many peo­ple com­plete­ly for­get to check the net­work, so they think why the refrig­er­a­tor does not start, and this often leads to sig­nif­i­cant mal­func­tions and break­downs. So, when the light is not on in the refrig­er­a­tor, first of all, you need to check the func­tion­ing of the elec­tri­cal out­let. For exam­ple, you can turn on the refrig­er­a­tor using anoth­er out­let that is work­ing.

When there are no defects on all points, then the rea­son, appar­ent­ly, is in the elec­tri­cal cir­cuit of the unit, which does not make sense to repair on its own.
