Today, modern houses and apartments have a large number of household appliances, which certainly includes a refrigerator. However, sad as it may seem, sometimes the highest quality and well-known specimens fail. Today it is not a rare case when the refrigerator does not turn on.
Signs and causes of breakdown
Knowing all the subtleties of the refrigerator, you can easily repair it yourself. There are many factors that will prevent the refrigerator from turning on. These signs include the following cases:
- the light is on, the light is on, but the motor does not work, there are incomprehensible clicks. This usually indicates a compressor malfunction. As a rule, the refrigerator starts to click without turning on, since the compressor does not work, a replacement is needed. These clicks are publishedstarting relayresponsible 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 there is a high probability that the thermostat, which is 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.
- the motor and light do not work. This usually indicates a problem with the mains voltage or a faulty plug.
Summing up, we can say that these signs are not always informative, since there is no big difference in these signs (the light is on or not, the motor is working or not working, 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 doesn't the refrigerator turn on after defrosting?
You need to defrost and wash the refrigerator only after disconnecting it from the mains. Despite the excellent insulation, it is extremely dangerous to wash a refrigerator that is powered by an outlet. 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 because of simple carelessness.
The real reasons for the breakdown of the unit are as follows:
- break in the electrical wire;
- malfunction of the plug or electrical outlet;
- oxidation or breakage of one of the contacts;
- malfunction of the thermostat;
- breakdown of the temperature sensor;
- malfunction of the control unit.
A professional is able to see and eliminate any of the listed reasons. The refrigerator is not a complex unit, but it requires special tools and skills to fix it.In general, when the refrigerator stops working after defrosting, but you do not have the skills and tools, it is recommended to call the master.

Types of breakdowns and remedies
A more difficult malfunction is considered 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 compressor makes noise... If you hear clicks, you can almost say with certainty that the compressor is faulty.
An equally significant malfunction is a breakdown of the thermostat. When it causes a malfunction in household appliances, it is very likely that the gas has escaped from 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 among themselves. This method allows you to check the health of the device. If the refrigerator is working, then it is necessary replace thermostat... When this does not work, you can test the defrost button (if there is one).
During normal operation of the defrost button, you need to test other parts of the refrigerator that are powered from the mains. You can do this with an ohmmeter. Such a check must be submitted to the protective as well as the starting relay. They are often housed in the same building. If it finds a break, the defective element should be replaced. When no defects were found according to these points, 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 network problems. When the problem lies precisely in it, then the owner is lucky. In order for the refrigerator to work normally, a voltage is required in the range from 200 to 240 V. If the indicator is not in this segment, then an emergency shutdown of household appliances occurs. This is especially true for today's refrigerators, since 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 off 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 a different outlet that is working.
When there are no defects at all points, then the reason, apparently, is in the electrical circuit of the unit, which does not make sense to repair on your own.
