The refrigerator is very cold - the reason

The main purpose of the refrigerator is to cool and store food. In the course of its functioning, the cooling device freezes and cools everything that is stored in it. However, if instead of fresh tomatoes you get tomato-ice from the device, then sound the alarm, since the fact that the refrigerator is very cold, the reason may be banal 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.

What to check first if the refrigerator is "frozen"?

In case 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. So do not rush to contact the customer service. Perhaps you can fix everything yourself.

Check the settings of

The most common cause of severe freezing of the device is the wrong position of the thermostat.

Important! The optimum temperature inside the refrigerator compartment is +5 degrees Celsius, permissible - a little lower in the "zero zone".This is enough to make all the products "feel" good.
New models of refrigerators have a "Super Frost" button, if there is such option, then check if it is switched on.

If this option is OK, inspect your home appliance and check the standard settings:

• in a mechanical refrigerator, the temperature regulator 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 a grueling heat, do not put the temperature regulator to maximum. A working refrigerator under any conditions will cope with its duties, but excessive load can break the home appliances in the shortest possible way.

Inspect the door seal

. To the second fault, which causes snow inside the refrigerator, the damage to the door seal can be attributed. If it has worn out, the inside of the refrigerator will receive heat from the kitchen. To compensate for excessive heat, the unit will start to freeze more than necessary.

Determine exactly this reason that the refrigerator has become very cold, you can by the following features:

• Permanent puddle near the door.
• Products freeze.
• Inside the refrigerator, a "coat" is formed.
• Inside the freezer, frost and not frozen water.

Important! To repair the fault, replace the rubber seal. It is easy to do it yourself, without the involvement of specialized specialists.

Check the drainage hole for obstruction

If the drainage hole is blocked, the condensate will not leave the refrigerator in a natural way. As a result, water accumulates in the lower part of the refrigerating chamber, under the vegetable boxes, thereby turning into ice, freezing everything in its path.

Important! To fix the problem, clean the drainage hole. This can be done independently with a syringe with warm water. Use for cleaning the system can and cocktail. After cleaning the hole, pour warm water into it to remove dirt.

The most common reasons why the refrigerator dries strongly

In addition to the above reasons for the fact that the refrigerator is very cold, there are others. But in these cases, without special skills and knowledge, you will hardly be able to correct the situation yourself.

Thermostat failure The temperature inside the unit is controlled by starting, respectively - stopping the compressor. The thermoregulator is responsible for this: it fixes the moment when the temperature has reached the necessary parameters, gives a signal to turn off the refrigerator.

If the thermostat fails, 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 thermostat can fail due to mechanical damage or, as a result of getting even a small amount of moisture on its contacts .

Inspect this part of the device, perform 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 master. An urgent replacement of the thermostat( thermostat) of the refrigerating chamber is necessary.

Refrigerant leakage( freon)

This fault is accompanied by a decrease in pressure, as a result - the compressor operates without stopping, as it tries to compensate for the necessary temperature in the freezer. As a result of this operation, the temperature in the refrigerating compartment is reduced.

Important! Freon can evaporate from small cracks in cooling tubes, so finding such a leak is very difficult. In this case, it is necessary to call a repairman to repair the refrigerating equipment in order to eliminate the leak and fill the unit with freon.

Blockage in the capillary system of the refrigerating chamber

If the cold store is very cold and the freezer is warm and, besides, the motor is active, making small intermediate pauses, the engine can not pump the refrigerant through the system due to the appearance of a "thrombus".

A burned engine oil may be the cause of the formation of the blockage.

Important! To solve the problem, it is necessary to clean the system itself and refill the refrigerator with freon. When carrying out preventive works, it is good to check the engine oil for quality and volume compliance, if necessary, to replace it.

The

air sensor has failed. If you have an electronically controlled refrigerator and everything is in order, but the refrigerator has become very cold, the air sensor has broken, which sends temperature data to the control board.

Important! The device does not receive a signal that in the "ice age" chamber, respectively - it continues to pump up the cold. This problem will be solved only by replacing the air valve of the refrigerating chamber.

The

switching valve is broken. If the main compartment of the single-compressor unit produces frozen food, and in the freezer compartment - the temperature is higher than the set value, the problem can be "sticking" the valve, which switches the cooling between the compartments.

In a faulty condition, the valve operates in a single mode - "cooling the refrigerating and freezing chambers".As a result of this "sticking": in the freezer - a hot summer, and in the refrigerator compartment - a severe winter.

The valve replacement can solve the problem.

Refrigerators with electronic control

Technique with electronic control is the most popular today. In this case, if the refrigerator is very cold, the reason is most likely in the malfunction of the temperature sensor.

In modern models of refrigeration devices, as a rule, there are several sensors, and the failure of one of them will certainly appear on the stable operation of the entire device.

As a result of a malfunction of the temperature sensor, the products 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 a strong cooling.

Important! In different models of devices, the interaction of the control program with sensor sensors can be different. If an abnormal situation occurs, and one sensor shows a temperature of +10( faulty) and another -2( serviceable), the control unit does not know which one is "wrong" and the refrigerator behaves "at random".

Tips:

1. Set the adjustment to a warmer mode, if the shift in the direction of frost is small - 2-3 degrees, then in refrigerated devices with electronic control it will help. But this is rather a temporary measure - if the temperature sensor starts to act badly, then it will not last long: from a week to a month.
2. A temporary solution may be to turn on the refrigerator via a time relay with the following cyclic setting: 30 minutes on and 30 minutes off. You can 45 minutes on, 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 for the time that is convenient for you.

The reasons for the severe freezing in modern refrigerators can also be:

1. Board malfunction( if the compressor does not turn off).
2. Valve malfunction( if not switched).
3. The "Super Frost" mode is selected.
4. Freon leak.
5. Filter dryer debris.
6. Clogged refrigerant circuit. Defective defrost system.
7. The thermostat is broken.
8. Compressor performance loss.

All malfunctions and causes can be revealed only by masters of refrigeration equipment, having carried out diagnostics with special tools. And we hope that your refrigeration unit will never fail, and will always function properly, and the "Ice Age" you can see only in the cinema.
