The situation when your refrigerator turns on and turns off after a few seconds can signal a serious problem.
Description of the problems and their characteristics
Why does my fridge freezer shut off? Malfunctions in the functioning of the compressor mean that there was a breakage of the winding, a short circuit of its turns, or a jammed motor. The element itself begins to greatly overheat and make specific noises. To protect the system from overload, the fridge design has a safety mechanism consisting of a special relay. It is this relay that triggers in such a situation, switching off the compressor a few seconds after switching it on. At that, further attempts to start the motor are accompanied by continuous operation of protection, due to which this problem occurs. It is also worth noting that the failure of the motor compressor implies its complete replacement, as any repair work is not able to solve this problem.
In most cases, the presence of such a malfunction also leads to the fact that it can turn on and immediately turn off. At the same time, the intervals during which the compressor operates may vary in duration. In such a case, the control unit ceases to perform its basic functions and commands the premature shutdown of the device. It should also be noted that in this case, the board must be re-flashed or completely replaced.
In the normal state, the starting protection relay is designed to control the start of the compressor and protect it from various kinds of overloads. This can be caused by voltage fluctuations, overheating of the main elements, or their failure. In its turn, from the moment of start-up to shutdown, the entire operation is under the control of a protection mechanism, which, if necessary, is triggered by the closing and opening of bimetallic plate contacts.
It is heated by the current flowing through it, after which it deforms, opening the contact and turning off the motor. As a result, the electrical conductivity of the plate can be disrupted, causing the compressor to shut down almost seconds after it is turned on. Eliminating such problems involves a complete replacement of the starter relay, which should only be performed by competent professionals.
Conclusion on the subject
There are several reasons why the refrigerator can turn on and immediately turn off. Each of them implies a serious repair, and in some cases, a large financial outlay. At the same time to carry out such work on their own is extremely not recommended to avoid more serious breakdowns.
