The refrigerator is an indispensable attribute of every kitchen. Its breakdown causes a lot of trouble and inconvenience. The most common reason is freezer just does not turn off. There are many breakdowns that can provoke continuous operation of equipment.
A hardware problem can occur in both modern and older models. Each owner of household appliances should understand that it is not always possible to fix the problem yourself. Some breakdowns require not only skills in working with electronic devices, but also knowledge in the field of refrigeration equipment. Do it yourself repair work if you can:
- fill freon into the system;
- detect and eliminate blockage;
- find a leak.
But still, you can try to independently find and eliminate the cause of the problem.
Why the freezer does not turn off?
Possible cause of breakdown
Many users are faced with the problem of continuous operation without stopping refrigeration equipment. How to find and eliminate the cause of this malfunction? This feature of the device may be associated with:
- improper installation;
- wear of components;
- wrong settings.
Important properly install the refrigeratorbut many miss this moment. Often, there is no air gap between the wall and the equipment body. Remember, it is strictly forbidden to install a refrigerator near heating devices. The room should not have a fever. The reason for the continuous operation of the equipment can also be a hot compressor that works without stopping for a long time.
Correct equipment layout
Do not forget about the age of the device. In old technology, the thermostat or compressor often fails. Accessories must be replaced.
Also, through negligence, you can set the maximum value on the thermostat. In this case, the compressor will automatically maintain the specified mode. Read carefully the functionality of your equipment. For example, the set super-freeze function may imply uninterrupted cooling.
Remember that the compressor on average should run no more than 15-20 minutes in one start. This should be followed by rest, which lasts at least 5 minutes.
How to set the temperature on the refrigerator
These are the most common reasons a refrigerator works for a long time. You can independently exclude one or another option. Some breakdowns can be independently corrected at home.
If the cause of the malfunction is different, you should contact the professionals.
Often enough to solve a problem defrost the refrigerator. If after this procedure no changes have occurred, the repair will not work. Often in such situations it is necessary to use the services of specialists. So, why doesn’t the temporary freezer shut off?
Malfunction in the refrigerator door
When the refrigerator door is loosened, warm air begins to flow into one of the chambers. She's heating up. In this case, the temperature sensor reacts, which cools the equipment. This problem can be encountered not only with a loose door closure.Rubber seals often wear out and are easy to replace on their own. To do this, you need to find a suitable seal and carefully fix it in the right place.

Increased room temperature
All household appliances have their own climate class. This is the optimum ambient temperature at which the equipment can function normally. After all, if the refrigerator is installed in a room with a temperature above +300C, the compressor will actively work without stopping. In this case, the equipment must be moved to a cooler room, or lower the temperature in the room.
Setting the temperature in the refrigerator
Compressor failed
Long operation of the equipment also indicates a compressor failure. The refrigerator is noisy, because it can not catch up to the required temperature. The cause of the breakdown may be damage to the seals or the increased temperature in the room. The solution is to replace the part. But make sure that the model meets the necessary characteristics.

Thermostat breakdown
In the refrigerator, the temperature sensor may fail. This is a problem with the electronics of the unit. It is enough to ring the part with a multimeter. If the contacts do not open when the relay setting is reached, you just need to replace the temperature sensor or thermostat.
Thermostat Replacement
There are problems that only a specialist can handle. Do not repair the device yourself if you are not confident in your abilities. It is necessary to contact the master in the cases described below.
Refrigerant leak
Freon refrigeration leak equipment is a problem that only a specialist can handle. You can verify this malfunction yourself by turning off the equipment for a day. If there really is a freon leak, then the refrigerator simply will not start. The specialist will detect the leak, seal the system and refill it with freon.
Freon replacement
Capillary blockage
Many housewives wonder why it is warm in the freezer, despite the fact that the device is active? Often this is due to clogging in the capillary system. This interferes with the normal circulation of freon throughout the system. Blockage can also occur due to accumulation of engine oil.
The master will clean the system, completely replace freon and engine oil.
Capillary tube replacement
Damage to the shift valve or control board
In single-compressor refrigerators, there is often a situation when the freezer is actively working. In this case, the refrigerator compartment is warm. Defrosting the device does not always help. In this case, there are two options for failure:
- sticking of the switching valve;
- control board malfunction.
The temperature switching valve should regulate the supply of cold air to the main department and the freezer of the two-compartment turquoise refrigerator. Sometimes the valve may “stick” in the “freezer cooling” position. At the same time, there will not be enough power for the refrigerator compartment. The problem can be solved by replacing the valve.
The cause of the malfunction of the refrigerator can also be the failure of the control board. In this situation, the compressor does not receive a shutdown command and transfer to another compartment. You should flash or replace the motherboard.
Installing the control board
Control board malfunction
Problems with the control board are often manifested by the prolonged operation of the freezer. In this case, simply does not receive a signal to turn off the motor, which provides cold freezer. You cannot fix this problem yourself.
It is enough to reflash or replace the part.
The freezer may not turn off for various reasons. Experts do not recommend repairing expensive equipment on their own, because you can only aggravate the problem.You can “reboot” the refrigerator yourself or fix minor problems. You can defrost the device at any time. But if after this procedure the problem persists, you should immediately contact a specialist.
I have an Indesit freezer. Two days the compressor does not turn off. The door is tight. The temperature in the freezer is normal. Room temperature 22 C.
