Why the refrigerator does not turn on: reasons and what to do?

[ad_1]

Mod­ern house­hold appli­ances are quite reli­able. But there are sit­u­a­tions when the refrig­er­a­tor does not turn on, which can cause food spoilage. It is not always worth rush­ing to con­tact the ser­vice, the prob­lem may have a sim­ple solu­tion.

Incorrect location or contamination

For prop­er ven­ti­la­tion, it is required to install the refrig­er­a­tor at a dis­tance:

  • at least 8 cm from the rear sur­face to the wall;
  • at least 5 cm on the sides of the device;
  • as far as pos­si­ble from heat sources such as stoves or radi­a­tors.

This is rel­e­vant for new devices, and if the device has been used for sev­er­al years, then the caus­es of inter­fer­ence in oper­a­tion may lie in the dust accu­mu­lat­ed in the con­denser.

If dust accu­mu­la­tion is indeed present, then it is nec­es­sary to turn off the device and clean it with a brush and vac­u­um clean­er. It should be not­ed that there are also coils under the bot­tom, they also need to be cleaned. You should also inspect the valves, they can also become clogged. If the refrig­er­a­tor does not start after these pro­ce­dures, then diag­nose the hard­ware.

Nutrition problems

This is one of the most com­mon sit­u­a­tions. To check if elec­tric­i­ty is sup­plied to the device, you need to open it. If the light is on, then every­thing is in order with the pow­er sup­ply. There are times when the volt­age in the mains is too low, and there­fore the device can­not start work­ing, then you should just wait until the nor­mal para­me­ters are restored.

Con­sid­er the rea­son when elec­tric­i­ty is not sup­plied to the sys­tem, and the light bulb does not glow. This may be caused by prob­lems with the out­let or cable, but first of all, you should make sure that oth­er devices are work­ing. Try to con­nect them to the same pow­er source, if a car­ri­er was used, then it is bet­ter to remove it.

Did the oth­er device start up nor­mal­ly? Then there are no prob­lems with the out­let, you need to diag­nose the cable or exten­sion cord. Any kinks in the con­duc­tor at an acute angle, heavy objects placed on it, can inter­fere with its oper­a­tion, and the insu­la­tion can also be dam­aged by pets, espe­cial­ly rodents. If any prob­lems are found, then you do not need to try to fix the cable — the refrig­er­a­tor may not work prop­er­ly after that, a com­plete replace­ment of the cord is required.

In this sit­u­a­tion, the light bulb will also not light. This is a spe­cial case when every­thing is in order with the pow­er sup­ply, but this can only be detect­ed by mea­sur­ing the volt­age on the device ele­ments. Often the refrig­er­a­tor tries to start, mak­ing clicks, but noth­ing hap­pens. The best solu­tion in this sit­u­a­tion would be to replace the defec­tive part, since the repair is unable to ensure the sta­ble oper­a­tion of the device in the future, and volt­age drops can adverse­ly affect the life of the motor.

If the light does not work sta­bly: at first it does not light up, and then turns on, or vice ver­sa, then the prob­lems may be due to a loss of con­tact in the cable or with the con­trol mod­ule (for mod­ern mod­els), you must imme­di­ate­ly turn off the device to pre­vent fur­ther dam­age. The same break­down can lead to the fact that the refrig­er­a­tor turns on and turns off after a few sec­onds. If this hap­pens sev­er­al times, then you should con­tact the ser­vice cen­ter.

Compressor failure

After dis­con­nec­tion, there may also be prob­lems start­ing the device. It is nec­es­sary to remem­ber the rea­son for stop­ping work, if the device turned off on its own, for exam­ple, there was an acci­dent in the mains, then this could adverse­ly affect the com­pres­sor. In this case, the refrig­er­a­tor clicks, but does not turn on.

With­out a work­ing com­pres­sor, it is impos­si­ble to use the device, so the refrig­er­a­tor motor needs to be replaced. Doing this your­self is not rec­om­mend­ed, it is bet­ter to con­tact a ser­vice cen­ter for help.

Also, the com­pres­sor may over­heat, then it is not able to turn on until it cools down, it is nec­es­sary to dis­con­nect the device from the pow­er sup­ply for a while (sev­er­al hours is enough), if after that it starts to func­tion prop­er­ly, then there are prob­lems in the cool­ing sys­tem.

If the work was sus­pend­ed for main­te­nance, and after defrost­ing the refrig­er­a­tor does not turn on, then you need to remem­ber the fea­tures of the device’s func­tion­ing recent­ly. Mod­ern mod­els do not accu­mu­late a lot of frost, if this hap­pens, then a fail­ure in the con­trol sys­tem is pos­si­ble, as a result of which the com­pres­sor worked too inten­sive­ly and could not with­stand the loads. If the mod­el is old, then you need to under­stand that equip­ment wears out dur­ing oper­a­tion, per­haps the life of the refrig­er­a­tor has expired.

No Frost system failure

Most peo­ple find out about this when the refrig­er­a­tor does not turn on after defrost­ing, although the accu­mu­la­tion of frost on the walls should have alert­ed the own­er. Some­times, due to incor­rect oper­a­tion of the sys­tem, drops of water can fall on elec­tri­cal appli­ances and cause a short cir­cuit, but more often mois­ture leads to loss of lubri­ca­tion prop­er­ties and increased wear of parts.

Evaporator

Replac­ing the evap­o­ra­tor or heat­ing ele­ment is not a dif­fi­cult pro­ce­dure — you just need to dis­man­tle the faulty one and install a new one in its place. There­fore, it is not nec­es­sary to call the mas­ter, but for this you need to have at least basic skills in han­dling elec­tri­cal appli­ances, oth­er­wise there are many rea­sons why you should not do it your­self.

You can use the video as an instruc­tion:

Here the process is demon­strat­ed on the exam­ple of a Sam­sung refrig­er­a­tor, but most devices have a sim­i­lar struc­ture.

Sensor failure

The com­pres­sor does not oper­ate con­tin­u­ous­ly, the motor starts only when nec­es­sary, when the tem­per­a­ture ris­es above the set lim­it. This should be sig­naled by spe­cial sen­sors mount­ed in the cam­era body, only after that the cool­ing process begins, it can­not be start­ed man­u­al­ly.

If the break­down occurred after the shut­down, then you need to remem­ber the cir­cum­stances that pre­ced­ed this. Have any actions been car­ried out with the device:

  • Some­times dur­ing defrost­ing, the own­ers try to remove the ice with sharp objects, which can cause dam­age, then the sen­sor may need to be replaced.
  • After wash­ing, water could get into the sen­sor, in most cas­es it is enough to let it dry, to do this, open the doors and pro­vide ven­ti­la­tion.

There can be many mal­func­tions that lead to the fact that the refrig­er­a­tor does not turn on. The main task of the own­er is to detect and elim­i­nate them in time or turn to pro­fes­sion­als for help. Care­ful atti­tude can sig­nif­i­cant­ly extend the life of the device.
