Modern household appliances are pretty 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.

Improper location or contamination
For proper ventilation, you need to install a refrigerator at a distance:
- at least 8 cm from the back to the wall;
- at least 5 cm on the sides of the device;
- as far as possible from heat sources such as stoves or batteries.
This is relevant for new devices, and if the device is used for several years, then the causes of interference in operation can be covered in dust accumulated in the capacitor.
If dust accumulation is really present, it is necessary to turn off the device and carry out cleaning with a brush and a vacuum cleaner. It should be noted that there are also turns under the bottom; they also need to be cleaned. Valves should also be inspected; they can also become clogged. If the refrigerator after these procedures did not start, then diagnose the hardware.
Eating problems
This is one of the most common situations. To check whether electricity is coming into the device, you must open it. If the light is on, everything is in order with power. There are cases when the voltage in the mains is too low, and therefore the device cannot start working, then you just need to wait until the normal parameters are restored.
Consider the reason when the system does not receive electricity and the light does not light. This can be caused by problems with the socket or cable, but first of all, make sure that other devices are working. Try plugging them into the same power source, if you used the carrier, it’s best 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 of the conductor at an acute angle, heavy objects placed on it can interfere with its operation, and the insulation can 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.

Incorrect operation of the start-up relay or control module
In this situation, the bulb will also not light. This is a special case when everything is in order with power, but it can be detected only by measuring the voltage on the elements of the device. Often, the refrigerator tries to start by clicking, but nothing works. The best solution in this situation is to replace the defective part, since the repair is unable to provide stable operation of the device in the future, and voltage drops can adversely affect the life of the device motor.
If the light does not work stably: first it does not light, and then it turns on, or vice versa, then problems may be associated with loss 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 failure can lead to the fact that the refrigerator turns on and off after a few seconds. If this happened several times, then you should contact the service center.
Compressor failure
After disconnecting, you may also have problems starting the device. It is necessary to remember the reason for stopping the operation, if the device turned off on its own, for example, an accident in the power supply network occurred, this could negatively affect the compressor. In this case, the refrigerator clicks, but does not turn on.
It is impossible to use the device without a working compressor, therefore, it is necessary to replace the refrigerator motor. 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, it is necessary to disconnect the device from power for a while (a few hours are enough), if after that it starts functioning properly, then there are problems in the system cooling.
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 in recent times. Modern models do not accumulate a lot of hoarfrost, if this happens, then the control system may malfunction, 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 is worn out during operation, the refrigerator may have expired.
Failure of the No Frost system
Most learn about this when the refrigerator does not turn on after defrosting, although the accumulation of frost on the walls should alert the owner. Sometimes, due to incorrect operation of the system, water droplets can fall on electrical appliances and cause a short circuit, but more often moisture leads to loss of lubricant properties and increased wear of parts.
Replacing an evaporator or a heating element is not a complicated procedure - it is only necessary to dismantle the faulty one and install a new one in its place. Therefore, it is not necessary to call a 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.
As an instruction, you can use the video:
Here, the process is demonstrated by the example of a Samsung brand refrigerator, but most appliances 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. Special sensors mounted in the camera body should signal this, only after this the cooling process begins, it cannot be started manually.
If the breakdown occurred after a trip, then you need to remember the previous circumstances. Have any actions been carried out with the device:
- Sometimes during a defrost, 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 find and eliminate them on time or turn to professionals for help. Careful attitude can significantly extend the life of the device.
