The refrigerator freezes very much - the reason
The main purpose of the refrigerator is to cool and preserve food. In the process of its functioning, the refrigeration device freezes and cools everything that is stored in it. However, if instead of fresh tomatoes you take out ice-cream tomatoes from the device, then sound the alarm, because the refrigerator can be very cold, the reason can be commonplace or vice versa - serious. In the article we will inform you how to avoid the “ice age”, and what to do if the refrigerator has become very cold.
to contents ↑What to check first if the refrigeration device is “frozen”?
In the case when you had to face the fact that the refrigerator is very cold - the reason for this phenomenon can become known without the help of specialists. Therefore, do not rush to contact customer service. Perhaps you can fix everything yourself.
Check settings
The most common cause of severe freezing of the device is the incorrect position of the thermostat.
Important! The optimum temperature inside the refrigerator compartment itself is +5 degrees Celsius, the permissible temperature is slightly lower in the “zero zone”. This is enough to make all products "feel" good.
Newer models of refrigeration units have a “Super Freeze” button. If there is such an option, check if it is turned on.In our separate review you will find out how to set the temperature in the refrigerator Samsung No Frost.
If the order is with this option, inspect your home appliance and check the standard settings:
- in a mechanical refrigerator, the temperature controller is usually between 2 and 3.5.
- for electronic units, the temperature is set in degrees: +4 or +6 degrees in the refrigerator compartment.
Important! Even if there is debilitating heat, do not set the temperature control to maximum. A working refrigerator will cope with its duties under any conditions, but excessive load can break household appliances in the shortest way.
Inspect door seal
The second malfunction, due to which snow forms inside the refrigerator, can be attributed to damage to the door seal. If it is worn out, then heat will come from the kitchen inside the refrigerator. To compensate for excessive heat, the unit will begin to freeze more than necessary.
It is possible to determine precisely this reason that the refrigerator began to freeze very much by the following signs:
- Permanent puddle near the door.
- Products freeze.
- A “fur coat” forms inside the refrigerator.
- Inside the freezer, ice and unfrozen water.
Important! To eliminate the malfunction - replace the rubber seal. Do it easily with your own hands, without the involvement of specialized specialists. Find out detailed instructions in our post "Repair of refrigerators - replacement of the seal."
Check for drainage hole
If the drainage hole is blocked, the condensate will not leave the refrigerator naturally. As a result, water accumulates in the lower part of the refrigerator, under the vegetable drawers, thereby turning into ice, freezing everything in its path.

The most common reasons why a refrigerator freezes severely
In addition to the above reasons that the refrigerator is very cold, there are others. But in these cases, without special skills and knowledge, you are unlikely to be able to correct the situation yourself.
Thermostat failure
The temperature inside the unit is regulated by starting, respectively, by stopping the compressor. The temperature regulator is precisely responsible for this: it captures the moment when the temperature has reached the required indicators, it sends a signal to turn off the refrigerator.
If the thermostat fails, then the “brain” of the device will not receive a signal that the temperature is low enough, and the unit will continue to freeze without turning off.
Important! The temperature regulator may fail due to mechanical damage or, as a result of even a small amount of moisture entering its contacts.
Inspect this part of the device, conduct a visual inspection for damage. If the unit does not turn off, and the products turn into ice, then turn off the device and call the wizard. Urgent needed temperature controller replacement (thermostat) of the refrigerator.
Refrigerant (Freon) leak
This malfunction is accompanied by a decrease in pressure, as a result, the compressor works without stopping, as it tries to compensate for the necessary temperature in the freezer. As a result of this operation of the unit, the temperature in the refrigerator compartment is reduced.
Important! Freon can evaporate from small cracks in the cooling tubes, so it is very difficult to find such a leak. In this case, it is necessary to call the repairman for refrigeration units in order to eliminate the leak and fill the unit with freon. Follow the link and find out how to fill the refrigerator with freon yourself.
Blockage in the capillary system of the refrigerator
If the refrigerator compartment is very cold, and in the freezer it is warm and, moreover, the motor is actively working, making small intermediate pauses, the engine cannot pump refrigerant through the system due to the occurrence of a “thrombus”.
Blocked engine oil may be causing clogging.
Important! To eliminate the malfunction, it is necessary to clean the system itself and refill the refrigerator with freon. When carrying out maintenance work, it’s good to check the engine oil for quality and volume matching, if necessary, to replace it.
Air sensor out of order
If you have an electronically controlled refrigerator and everything looks fine, but the refrigerator has become very cold, then the air sensor has broken, which sends temperature data to the control board.
Important! The device does not receive a signal that there is an “ice age” in the camera, respectively - it continues to pump up cold. This problem will be solved only by replacing the air valve of the refrigerator.
Switch valve broken
If the main compartment of a single-compressor device delivers frozen food, and in the freezer the temperature is higher than the set value, the problem may be in the “sticking” of the valve, which switches the cooling between the compartments.
In a faulty state, the valve operates in a single mode - “cooling of the refrigeration and freezer chambers”. As a result of such “sticking”: hot summers in the freezer, and harsh winters in the refrigerator compartment.
Replacing the valve can solve the problem.
Electronically controlled refrigerators
Electronic control technology is the most popular today. In this case, if the refrigerator is very cold, the cause is most likely a malfunction of the temperature sensor.
In modern models of refrigeration devices, as a rule, there are several sensors, and failure of one of them will certainly be reflected in the stable operation of the entire device.
As a result of a malfunction in the temperature sensor, the food will freeze, even in the refrigerator compartment. If the sensor sensor shows a temperature higher than it actually is, then the control unit will make the compressor work longer, which will lead to strong cooling.
Important! In different device models, the interaction of the control program with the sensor sensors may be different. If an emergency occurs, and one sensor shows the temperature +10 (faulty) and the other -2 (serviceable), the control unit does not know which of them is “wrong”, and the refrigerator behaves “randomly”.
Advice:
- Set the adjustment to a warmer mode, if the shift towards the frost is small - 2-3 degrees, then in electronic refrigerated appliances this will help. But this is rather a temporary measure - if the temperature sensor began to junk, then it will not work for long: from a week to a month.
- A temporary solution may be to turn on the refrigerator through a time relay with the following cyclic setting: 30 minutes on and 30 minutes off. You can turn on 45 minutes, 45 off, but remember that the off time should not be less than 15 minutes. Products in this mode will stop freezing, and you can call the wizard at a time that is convenient for you.
The reasons for severe freezing in modern refrigerators can also be:
- Board malfunction (if the compressor does not turn off).
- Valve malfunction (if it does not switch).
- Super Freeze selected.
- Freon leak.
- Dehumidifier filter clogged.
- Clogged refrigerant circulation system.
- Defrost system malfunction.
- The temperature controller is broken.
- Loss of compressor performance.

All malfunctions and causes can only be identified by the master of the refrigeration equipment, having diagnosed with special tools. And we hope that your refrigeration unit will never fail, and will always function properly, and you can see the “Ice Age” only in the cinema.
