If your refrigerator does not want to work in normal mode, first, check the voltage in the network. Or just take a close look at the lamp: if the light is constantly flashing, it is quite possible that the refrigerator stops the compressor due to power surges. True, most often only new, especially "smart" models of refrigerators follow this way. If an old model has settled in your kitchen or everything is in order with the voltage, then there is some kind of malfunction. A common symptom is a constant on / off compressor with a noticeable click, the intervals can be either constant or random - depending on what is broken. Unfortunately, such symptoms indicate a serious breakdown of one of the internal devices of the refrigerator, up to and including failure of the compressor. But the reason may be the wrong voltage of the mains - start with it. The compressor of the refrigerator does not work all the time, therefore the concept of "immediately turns off" requires diagnostics. The compressor motor or winding protector may be defective, and the compressor may be mechanically blocked. Frequent reasons for reduced refrigeration capacity are coking or copper platings due to moisture or noncondensable gases in the system. Blown gaskets or broken valve plates are due to peak pressures being too high and short-time pressure peaks as a result of liquid hammering in the compressor, which may be due to a high refrigerant charge in the system or a blocked capillary tube. The voltage may be too low or the pressure too high for the compressor. Pressure that is not equalized causes the motor protector to cut out after each start and will eventually result in a burnt motor winding. A defective fan will also affect the compressor load and may cause the motor protector to cut out or a gasket to blow. If the compressor will not start or is cold, up to 15 minutes may pass until the winding protector cuts the compressor out. If the winding protector cuts out when the compressor is hot, up to 45 minutes may pass until the protector switches the compressor on again. Before starting to systematically locate the fault, it is a good rule to cut off the voltage to the compressor for 5 minutes. This ensures the PTC starting device, if present, is cooled sufficiently to be able to start the compressor. Should a brief power failure occur within the first few minutes of the refrigeration process, a conflict situation (interlocking) may arise between the protector and the PTC. A compressor with a PTC starting device cannot start in a system whose pressure is not equalized, and the PTC cannot cool quickly enough. In some cases, it could take up to 1 hour until the refrigerator runs normally again.
