The refrigerator runs for 5 seconds and turns off

For us, there is nothing new in the operation of the refrigerator when we hear periodic shutdown / on. This is the specificity of the operation of the cooling system, in particular the compressor. The on / off frequency depends on which mode it is in( how much it freezes).But it's absolutely abnormal that your home appliances turn off with a minimum period of time, namely, - the refrigerator runs for 5 seconds and turns off. With this operation, the temperature regime will not be respected and the products may deteriorate. Accordingly, we need to understand the causes of this phenomenon and fix the problem. How to do this, you will learn from this article.

What happens to your refrigerator?

There are many different reasons why the refrigerator runs for 5 seconds and turns off. First, check the voltage in the network. Due to the voltage drop in the network, the compressor stops. Modern smart refrigerators are most often cleaned from all sorts of incidents. But the list of problems why the refrigerator is turned on for a few seconds and turns off, versatile.

How to determine the working period?

The concept is turned on / off individually. Maybe you think that with a refrigerator problem, it will not turn on for a long time. In fact, this is the specific nature of the work. Therefore, we suggest that you use a formula that determines the ratio of idle time and refrigerator performance. You need to change the time and idle time. Then the compressor start-up period.

Important! When the compressor works in the interval - 2 minutes, it works 10 rest, we derive the formula 2 /( 2 + 10) = 0.167, it is considered incorrect. The correct operating mode for a refrigerator should be with a coefficient ranging from 0.2-0.9.

So, if you calculated a coefficient that does not meet these standards, then there are some problems with its cooling system. And what can lead to this, we will consider below.

Causes of malfunction

The reasons for the fact that the refrigerator runs for 5 seconds and turns off can be different:

1. Compressor failed.
2. The start relay was burnt.
3. Problem with the electronic unit.
4. Low voltage in the network.

Diagnostic methods

And very important is the correct diagnosis of breakdown. Correct diagnosis is the first step to troubleshooting. At the beginning of repair the simplest malfunctions are checked. It is necessary to follow the path of least resistance - from easy to difficult.

Your tactic:

• Check the voltage in the network.
• Inspects the socket check the contacts.
• Check / ring the compressor.
• Inspect the relay.
• Check the electronic unit.
  

These are the main directions of checking the malfunction of your refrigerator.

It is very simple to determine the operation of the refrigerator by ear. You just need to listen to him. If the compressor start time is minimal, then there is a problem. This has a very negative effect on its shelf life. Replacement of the compressor is not expensive, and you may have to visit the service center.

May have a problem with the relay, then replace it. This is an inexpensive procedure, plus it does not require much time and effort. During the survey, it may be found that the control card has failed. Replacement of this device will require you to make small financial investments and a possible appeal to a specialist.

Remedies for the breakdown of the

In the event of a breakdown, we will be guided by the rule that we are not professionals, but pioneers. It will rather not repair the fault, but a detailed clarification, through disassembly and the method of scientific poking.

So, we solve the problem that the refrigerator works for 5 seconds and turns off:

1. To check the efficiency of the compressor, you need to measure the resistance of its windings. It must correspond to the nominal value. Just take and check between each pair of terminals. If you understand that everything works, then you can safely breathe out - the motor is all right.
2. Let's move on to studying the relay. Malfunction of the relay-regulator can be determined by eye, with the help of disassembly. The cause is determined immediately, the breakdown is common. Take and replace with another relay. If the refrigerator has started to work properly, then you have independently coped with the task. In some cases, when the core of the solenoid is destroyed, a wire is installed instead of it. But this is only in older models. Usually in modern refrigerators the relay works so quietly that it is not audible when it switches. And nobody turns his attention to turning it off. The alarm starts to sound when the refrigerator stops working or works for 5 seconds and turns off.
3. If the problem of malfunction lies in the failure of the control card, you can limit the flashing. But this must be understood by a specialist. The board is a think tank and needs the right approach.
4. To check the voltage in the network, you need a special tester - a multimeter or a probe. Both can help you. But nevertheless, it is better to have a special tester with a display that will show not only the absence of current in the network, but its magnitude. It's very simple: turn on the device to measure AC voltage. For the household network, switch to 750 volts. As soon as the display shows three zeros, insert two probes in the corresponding holes and measure the voltage.

If you are sufficiently well versed in the repair of household appliances, then this type of repair you will be able to. And in general, of course, an appeal to a specialist will be the most correct decision. Masters will relieve you of the need to understand the wisdoms and subtleties of the refrigerator's cooling system. Especially for such procedures, a suitable tool should be available, plus knowledge and skills.
