Why doesn't the refrigerator turn off?

The refrigerator cannot work continuously. Usually he will make a noise for about fifteen to twenty minutes, then turn off briefly, then everything starts all over again. Continuous operation is harmful for both the unit and the products, but situations where there are no interruptions in operation are not so rare. Why doesn't the refrigerator turn off? The reasons can be very different, and we will discuss them now.

Why doesn't technology take breaks?

The refrigerator is a rather complex unit, consisting of many components. Failure of any of them can cause disruptions in the operation of the entire system. In addition, the behavior of such devices is quite strongly influenced by external conditions.

The refrigerator may “not want to” turn off because:

• the unit does not stand still;
• the door is not tightly closed;
• the freezing mode is set;
• the seal is worn;
• faulty relay;
• the thermostat is out of order;
• refrigerant evaporates;
• compressor worn out;
• the capillaries are clogged, that is, the refrigerant circulation is disturbed;
• control board crashes.

What to do if the refrigerator does not turn off and freezes very much?

First of all, if the refrigerator does not turn off, you need to inspect the unit. This will make it possible to exclude the reasons that arose due to your carelessness or which can be eliminated with a slight movement of the hand.

• disable the freeze function if it was mistakenly turned on;
• see where and how your refrigerator is;
• make sure that the refrigerator door closes tightly.
• Pay attention to what temperature is outside.

Freeze mode

If your refrigerator has a freezing mode, the cause of too hard work of the unit may be a banal carelessness. Check if you have set the mode correctly and correct the error. If in doubt, use our instructions to set a suitable temperature in the refrigerator.

Where and how does it stand?

You correctly determined the mode, but the refrigerator does not turn off - what should I do? See how it is installed:

1. There should not be pipes or steam heating batteries nearby.
2. The unit should not stand close to the wall - there should be gaps.
3. A stove, and especially an oven, are not the most suitable “neighbors” for refrigerators and freezers.

Important! An oven with pyrolysis cleaning, located next to the refrigerator, is especially dangerous.

Tightness

If the tightness is broken, warm air from the room enters the unit. This does not allow the temperature to automatically drop to the desired mark. The refrigerator does not understand this, it seeks to establish the microclimate that you have determined for it, and continues to work.

There may be several causes of leakage:

• the door is not set correctly;
• the seal is worn;
• something is stuck between the case and the door.

If it's all about gum, follow the link and read step-by-step instructions to help you quickly repair or replace seal.

Important! Indesit refrigerator does not turn off - what to do? Immediately look at the door fastening - a similar defect that occurs during assembly is especially typical for refrigerators of this brand. You can, of course, try to rearrange the part yourself, but perhaps this is only a few models. So in any case, it is better to call the master - such a repair will cost quite inexpensively.

Heat

When the room is too hot, the refrigerator operating in normal mode cannot automatically maintain the temperature that is required of it. He spends a lot of energy - and, accordingly, the compressor works without respite.

Important! When buying a refrigerator or freezer, pay attention to their climate class - this will help to avoid such problems.

What to do if the refrigerator does not turn off for this reason:

1. You can try to lower the temperature in the room.
2. Protect the refrigerator from direct sunlight.
3. Turn on the air conditioner or fan.

Important! The room should be ventilated very carefully - the temperature outside the windows can be even higher than in the room. The refrigerator itself will help to make the air in the room cooler.

4. Freeze 2-3 bottles of water.
5. Put them near the refrigerator.
6. Place a fan nearby and turn it on.

If the unit began to act up in the winter, make sure that there is no heater next to it.

Internal causes

You have carefully examined everything, eliminated minor problems - but there’s no sense. Well, you have to deal with the inside of the unit. Most often, you have to deal with unemployed:

• a compressor;
• Thermostat
• refrigerant system.

Compressor

The compressor is the heart of the refrigerator. It is an asynchronous motor made in compliance with international standards.

Important! Why is such an engine used? Because it should produce as little noise as possible. The maximum is 58 dB, but there are also much quieter units that produce noise no more than 43 dB.

Accordingly - the motor is constantly running at low speeds. The piston moves due to the translational motion of the core of the coil. With the engine, everything is safe in three-phase mode.

However, in an ordinary apartment where 220 V voltage is supplied, there are almost never optimal conditions for starting. There is a shift by one phase, the voltage is supplied to the starting winding - part of the stator. As a result, the rotor and stator enter the correct mode, after which the need for such a winding disappears, but the voltage is still supplied there, the engine heats up and eventually the relay sticks. Contacts are attached to each other, as a result - there are no interruptions in work. Prevention of this breakdown and other defects associated with the instability of the power supply network is quality voltage regulator.

Thermostat

This device is responsible for the timely supply of a signal to the contacts. Accordingly, the relay does not open and the engine does not stop. How to find out this reason why the refrigerator does not turn off:

1. Check the device with a multimeter.
2. If the contacts do not open for this reason, replace the thermostat or the temperature sensor.

Malfunctions in the refrigerant circuit

You can cope with the installation of a new temperature sensor yourself. But if there are malfunctions in the refrigerant circulation system - most likely, you will have to call the master or take the refrigerator to the service center.

Important! In this case, the amount of freon decreases, the “smart” technique seeks to compensate for its lack due to the intensive work of other components. It is necessary to add freon and eliminate damage to the system - these can be microscopic cracks.

At home, determining the location of the leak is almost impossible. But one should have an idea of ​​the features of the process. Read about them in a separate article. "Freon replacement".

Capillaries clogged

The refrigerant circulation system is somewhat akin to the human body. It is all riddled with “vessels” - capillaries. The reason that the refrigerator works without a break is very often hidden in the evaporator - the capillaries become clogged and an ice plug forms.

Important! If you are thinking about what to do, why your Atlant refrigerator does not turn off, pay special attention to this system. In such models, such a malfunction occurs more often than in analogues from other manufacturers.

An experienced craftsman can establish a place for a “blood clot” and repair a refrigerator without having to remove it from the apartment. However, sometimes you have to disassemble the unit almost completely. In this case, the refrigerator will have to be taken away.

If the refrigerator does not freeze hard, but continuously

The reasons for this phenomenon may be:

• worn seal;
• leak of freon.

As in the case of severe freezing, the seal does not provide sufficient tightness - most often because it is too old. The solution suggests itself: to make the unit stop, you need to change the seal.

Important! The sealant is needed exactly the same as it was.

No frost refrigerator

Often it seems to the owners of such units that the refrigerator does not turn off, but in fact, it works in absolutely normal mode. The reason is confusion. Inexperienced owners do not always distinguish engine noise from fan noise. It is quite possible that it will not have to be repaired, but it is necessary to test the refrigerator.

But sometimes such a refrigerator really stops turning off. The most common cause is a malfunction of the heater in the evaporator. The item is usually changed.

Two-compartment refrigerator

A two-compartment refrigerator rarely completely fails. Usually, the problem arises in one single compartment, most often in the one where the temperature is higher. The freezer is working fine. Malfunctions arise for the same reasons as other units.

Why is this problem worth considering?

Noticing that the refrigerator has stopped turning off, be sure to immediately try to figure out why this happened and fix the problem. The consequences of your neglect can be very deplorable - the compressor, not knowing the rest, will soon break completely.

Important! With continuous operation, the engine lasts no more than six months. Replacing an engine can be expensive. For some models, the cost of the compressor is a quarter, or even half the price. Add to this the cost of work - it turns out a little cheaper than buying a new refrigerator. So do not put off and do not hope that it will correct itself.

The unit does not want to work

Owners of refrigerated cabinets and freezers are faced with the exact opposite phenomenon, when the units simply do not want to work, although there seems to be no damage.

For example, the refrigerator seems to have started working, the engine is noisy, but a couple of minutes pass - and everything stops.

How to proceed?

1. Check mains voltage.
2. Inspect the outlet and contacts.
3. If everything is in order, inspect the relay and compressor.
4. For the new model - check the electronic board.

Problems with refrigerators of popular models

Each company that produces refrigeration equipment has its own advantages and disadvantages.

Atlant

The Atlant refrigerator is characterized by reliability and durability. They serve for quite some time, however, they may also refuse to take breaks in work:

• For all Atlantes, the problem usually arises due to the thermoregulator tube - it goes away, and it is quite simple to put it in place.
• As for older models, they are sensitive to high temperature indoors.

Biryusa

This simple and reliable refrigerator can start to work continuously if it has:

• failures in the relay;
• malfunctioning thermostat;
• malfunctioning compressor.

Important! The optimum temperature for Biryusa is 16-32 ° C.Abnormalities in operation occur both at higher and lower temperatures.

Nord

Aggregates of this brand work clearly and correctly, failures rarely occur. However, if such a refrigerator suddenly stops turning off - look for a problem in the thermostat or start relay.

How to care for the refrigerator?

The continuous operation of the refrigerator occurs not only due to inattention or failure of individual nodes. Sometimes the unit may begin to be capricious, because it is poorly looked after:

• Do not defrost on time;
• thawed too aggressively;
• cause mechanical damage.

Important! Ice should not freeze on the walls! The refrigerator may stop taking breaks after the first such experiment. Look at the instructions - it probably says how often you need to defrost your machine.

Defrost the refrigerator gently and do not try to speed up the process - it will not lead to anything good, but you can do much harm.
