Why does the refrigerator turn on and off immediately: troubleshooting

It is an extremely unpleasant situation when expensive household appliances break down in the house, especially such an important and necessary one as a refrigerator. A breakdown in which this device turns on and turns off after a few seconds is not uncommon.

How do you diagnose the problem?

As you know, the compressor of a refrigerator is designed for intermittent operation. It turns on only for a certain time of operation. Turning off the device is the norm. But how to understand that the device often turns off and requires repair? Most often, a breakdown is indicated by an attempt to start the compressor: the unit emits an unusual buzz, and after a few seconds it immediately dies down. To calculate whether a device designed to compress and pump refrigerant vapors is working properly, you can resort to a mathematical method. If the compressor is designed for two minutes, and then the remaining 10 minutes it rests, then the following calculations are made: 2: (2 + 10) = 0.166. From the result obtained, it becomes clear that the refrigerator is faulty, since the coefficient during normal operation is 0.2 - 0.9.

How to identify a fault by sound?

The refrigerator can turn on and then immediately shut down if something is out of order. To understand what is the cause of the malfunction, and which part of the refrigerator needs repair, it is necessary to analyze the sound when it turns on and off.

refrigerator diagnostics by sound

If the device started up for a few seconds, and a click was heard before shutting down, while the motor itself was usually louder, it is likely that the compressor will have to be repaired or changed. A very part of the reason for the rapid shutdown of the refrigerator is the start-up relay through which the motor starts.

If the usual work intervals are violated, you should pay attention to the electronic board. Often, in the event of a breakdown, it gives the wrong signals - the refrigerator turns on, but after working for only a few seconds, it turns off.

Reasons for quickly turning off the refrigerator and the possibility of their correction

Failures and power surges

In modern devices, although there are multiple systems that provide security against network instability, sharp and frequent fluctuations can still affect correct performance. To save expensive equipment, it is best to purchase additional protective equipment and connect the device to the mains source only through them, for example, a voltage stabilizer. Otherwise, the compressor, electronic control unit and other important parts of the refrigerator may not withstand interruptions and fail, which will entail costly repairs.

Control box problems

Any home appliance that has a control board becomes vulnerable due to this small but very important detail. If the program is broken, then the commands begin to arrive at different intervals. The motor turns on and off in a chaotic manner. The most likely reason for a breakdown in an electronic unit is an unstable power supply. In this case, the board must be reprogrammed or replaced. But it is better to give the right to make such repairs to a specialist, especially since he has all the equipment for accurate diagnosis.

The compressor is out of order

This is the most expensive part of the refrigerator to replace and repair. The compressor performs an important function - pumping out freon in a gaseous state from the evaporator, it supplies it under pressure to the condenser. The gas is then compressed and cooled, condensing it to a liquid state. Through the capillary expander, the coolant flows back into the evaporator where it absorbs heat.

To understand if the compressor is working properly when the refrigerator is often turned off, you need to know the resistance of its windings - each pair of terminals. If the winding is damaged, or an interturn short circuit occurs, the following often happens: the device turns on and continues to work, but already at an increased load. Therefore, the compressor gets hotter than usual during operation. The relay tries to facilitate the work of the motor, and therefore it works ahead of schedule. In modern models, this part of the device is non-separable, therefore it must be completely replaced.

The performance of the start-up relay is broken

This part often fails due to physical wear or overheating during operation. The most harmless breakdown, which is the reason why the refrigerator turns off after a few seconds of operation. It is much cheaper to fix this problem than to repair the compressor itself or the control unit.

replacing the relay in the refrigerator

If the device turns on and off immediately due to the relay, before changing this part, you can try to repair it. To do this, it is worth checking the solenoid core. Popular wisdom is inexhaustible, so some craftsmen came up with the idea of ​​inserting a wire of the appropriate size or an ordinary metal rod from a ballpoint pen instead of a damaged core. But this method is not always effective, since modern coil models have a different structure. The conductor in such a solenoid is in the form of a pill. It is he who can become the source of why the refrigerator quickly turns off if it burns out.

If the equipment still stops working, it is better to call an experienced foreman who will diagnose and then make a quality repair. The specialists have in stock the components of the highest class, especially since they also have warranty obligations. An experienced craftsman will quickly figure out why the device turns on and off immediately, and will professionally eliminate the cause of the breakdown.
