Why does the refrigerator freeze: what to do if food freezes in the refrigerator, what is the reason why it freezes

The refrigerator is very cold - the reason

It happens that food only freezes in the upper compartment of the refrigerator, but the freezer operates as before. Why is she so cold? There are several reasons:

The thermostat malfunctions, and then the compressor works without stopping, the walls of the chamber are covered with ice, and the food freezes.
The door is not closed tightly or the rubber seal is torn. Ice freezes on the back wall, food freezes. There is a puddle at the bottom of the chamber - the snow is melting from the warm air. The compressor is running.
The drainage hole is clogged during drip defrosting. At the bottom of the chamber, puddles turn to ice, creating a cold base on which food freezes.
If the refrigerator runs continuously, the cause may be a freon leak.

It makes sense to check whether the freezer mode is set in the device, then the refrigerator works without stopping and it will become very cold in both chambers.

What to do if your new refrigerator gets very cold? It may be necessary to adjust the thermostat - set it to a higher temperature.

Causes of severe frost

The temperature regime in the refrigerator compartment may be disrupted for other reasons. If the regulators are normal, check the functionality of additional mechanisms responsible for the operation of temperature indicators.

Seal wear

There is a special rubber gasket on the doors of the refrigerator compartment, which becomes unusable over time due to constant mechanical stress. Cracks and kinks appear on the seal, causing warm air to enter the device. So the refrigerator gradually lowers the temperature to compensate for the difference.

Because of this, the following happens:

the cameras begin to freeze;
an ice “coat” is formed.

As a result, all food in the refrigerator gradually freezes.

No Frost system failure

Most models are equipped with an automatic defrosting system, which eliminates the need for manual defrosting. Self-defrosting occurs when the air sensor transmits a signal that the temperature has dropped. If such a sensor breaks down, the device receives incorrect information about the temperature conditions and continues to intensively produce cold.

Refrigerant leak

This occurs as a result of gas escaping from the main system. Therefore, the compressor begins to work harder, which affects the temperature in the upper chamber of the equipment.

Blockage in the drainage system

This happens when the drainage hole is clogged. The accumulated condensate is not able to leave the refrigerating chamber, which is why it gradually accumulates in the lower section of the unit chamber and freezes, turning into ice.

Broken thermostat or air sensor

The thermostat or air sensor often breaks due to moisture getting on the parts or due to other mechanical damage. These elements are responsible for the correct display of temperature in refrigerator compartments. Due to damage, the refrigerator does not receive signals about temperature conditions, so it continues to blow cold.

Valve fault

The part is responsible for temperature control and the relationship between the main compartment and the freezer. The mode switching valve can sometimes stick, causing a violation of the modes. The temperature in the freezer becomes too high and the main compartment becomes frozen.

If there is a malfunction in the temperature conditions of the refrigerator, the breakdown must be repaired as quickly as possible. Ignoring the problem can lead to increased operation of the compressor, which will trigger an emergency shutdown of the entire unit.

In case of breakdowns, contact the service center if you do not have the experience and necessary tools for such repairs. If you do not repair the parts right away, the equipment may end up undergoing serious repairs, the price of which will be expensive. But more importantly, in this case the risk of poisoning from spoiled products increases.

It is easier to correct minor malfunctions and defects in the operation of the refrigerator than to later buy a new unit and allocate money for it.

Why did the refrigerator become very cold?

The heat extraction system in a refrigerator with one compressor is dynamic. This means that a decrease in temperature in both chambers is possible for a short period. After all, the compressor has not become more powerful, and no refrigerant has been added. The flow of cold is ensured by the continuous operation of the compressor. This is exactly what will happen if the thermostats in the chambers are simultaneously set to super freezing and fast cooling. The refrigerator gets very cold, but not for long. If you forgot to turn off the intensive mode, everything will freeze.

The electronic control unit has failed, the air sensor has failed, the refrigerator can get very cold, or it can get hot. Why you should call a specialist for diagnostics is not obvious. The more complex the equipment, the more variants of breakdowns with similar symptoms.

It happens that the freezer in the refrigerator gets very cold. You need to check if the mode is switched to quick freezing. Another reason could be refrigerant redistribution through the magnetic damper into one of the chambers. If it is faulty, it will cause the refrigerator to become very cold and the freezer to be warm.

If the refrigerator begins to freeze too much without delay, you need to contact the service department. Increased load on the nodes will lead to an accident. Instead of refilling with freon, you will have to change the compressor.

How to fix a refrigerator that freezes too much

Suppose the temperature adjustment did not lead to the desired result, and the unit is too cold, then an external inspection should be continued.

It is impossible to leave equipment in a faulty condition, as increased load on the compressor can lead to an emergency shutdown.

Seal wear

Due to the rubber drying out, cracks and kinks appearing on it, the refrigerator door does not close tightly, and warm air constantly enters the chambers. In this case, the back wall is covered with snow, and water stands in the drainage system without having time to evaporate. The compressor does not stop, trying to maintain the set temperature, and freezes food beyond necessity. The food in the depths of the compartment freezes. The situation can be corrected; to do this, you will have to change the old seal.

Replacing the seal

No Frost system failure

An imbalance occurs during the defrosting of one of the chambers of the No Frost refrigerator: the freezer tends to increase the temperature to remove ice, and the adjacent compartment tends to lower it. Normally, they should work in cooperation. This can happen when the capillary system is clogged, when a blood clot forms in a thin tube, and the motor is unable to pump freon. What to do with refrigerant leakage through damaged structural elements? This type of breakdown will require cleaning and refilling.

Blockage in the drainage system

There is cold air in the refrigerator, in the freshness zone there is a puddle of water with a crust of ice, and condensation flows down the back wall. Obviously, the moisture is not being drained outside the refrigerator compartment, and the cause may be a clogged drain tube. Cleaning and flushing the water drainage hole will save the situation. Using a thin flexible wire, carefully push the debris plug, and then pour warm water through the syringe or syringe several times under pressure into the outlet channel.

Cleaning operations should be carried out only after disconnecting the refrigerator from the network.

Broken thermostat or air sensor

Electromechanical refrigerators are equipped with a manual thermostat, which is usually located under the freezer compartment. When it fails, it is not noticeable from the outside, only the household appliance freezes or stops cooling altogether. The thermostat needs to be checked with a tester, and the problem can be solved on the spot. Otherwise, you cannot do without calling a specialist.

In models with an electronic control unit, the microclimate is monitored by a sensor. It is better not to penetrate the digital “brain” of a modern refrigerator yourself, but to entrust the matter to a professional.

Checking the Thermostat

Valve fault

A refrigerator with one compressor sometimes cools the food in the main compartment too much, and the temperature in the freezer is higher than the set temperature. This happens due to the fault of the electromagnetic switch at the junction of the circuits, which is supposed to alternate cooling modes, but for some reason it gets stuck. A new working part needs to be installed.

The listed reasons for malfunction are inherent in products from different manufacturers: Atlant and Indesit, Bosch and Samsung. An unexplained change in temperature in the refrigerator should alert you. It is always easier to fix something not very significant than to pay for expensive repairs or buy a new unit.

The top compartment of the refrigerator is very cold

If the refrigerator begins to get very cold, the first thing you need to do is check whether the regulators are set correctly. What should I do if the chamber freezes over and the compressor works despite the regulator dial being switched to the zero position? Stop the refrigerator, change the thermostat yourself, or call a technician. An electronically controlled refrigerator uses an air sensor. It must be changed by a specialist.

It happens that the refrigerator freezes too much, and the meat in the freezer thaws. What to do if the compressor runs without stopping? Presumably, the capillary tube was clogged due to decomposition of oil and refrigerant. A specialist will remove the blockage or replace the capillary.

Other reasons

Experts also name less common reasons why the unit produces excess cold. They require close attention and timely repairs.

Broken thermostat or air sensor

If your refrigerator gets too cold, the air sensor or thermostat may be faulty. In this case, the lower or upper camera can work properly. Such signs indicate that the control system does not receive a signal that the user-set temperature has been reached. As a result, the engine runs longer or continuously.

In this case, it is necessary to replace the thermostat or air sensor. The problem should not be ignored, because it affects the motor and it wears out faster. The cost of repairs reaches 5,000 rubles.

Valve fault

If the refrigerator starts to get very cold, you should pay attention to the switch valve. When it is faulty, disruptions in temperature conditions are observed. Ice may form in the refrigerator compartment, and food may begin to melt in the freezer. To solve the problem you need to call a specialist. He will replace the valve and adjust the cooling system.

Incorrect thermostat position

When an Atlant or Samsung refrigerator produces ice, it is recommended to check the set temperature. Often the reason lies in the incorrect position of the regulator. You should change the settings and check the cameras after a day. If the situation has not changed, it is better to invite a specialist to find the breakdown and make repairs.

Freon leak

Most users do not know what to do if the refrigerator gets very cold. The problem does not always lie with the compressor or thermostat. During operation, materials wear out and cracks may form through which freon escapes. As a result, the motor starts working without stopping to maintain the set temperature.

To correct the situation, you should call a specialist. He will carry out diagnostics, fix cracks and pump in the optimal amount of freon. After this, there will be no excess people in the cells. The cost of repairs is up to 5,000 rubles.

When your refrigerator produces excess cold, it can be difficult to know what to do. First of all, it is recommended to check the set temperature. Children can play and change settings. Adults sometimes accidentally touch the regulator. As a result, ice appears. If this does not help, it is better to call a specialist for diagnosis and repair.

The refrigerator started to get very cold - the food is freezing

It will be a real disaster for users if the refrigerator gets very cold. What to do if the cavity inside is frozen with a fur coat, food touches the ice, loses its taste, and freezes. First of all, you need to find the cause of the disaster.

check the settings of the refrigerator parameters and modes;
make sure the door closes tightly;
clean the drain hole if it is clogged with ice;
make sure that the thermostat is working properly and responds to commands.

Only a master can check how the electronic control works, reconfigure and debug the mode. In the meantime, you need to move the food away from the walls, move it to the warmest part, closer to the door.

The refrigerator is very cold and does not turn off

If the refrigerator does not turn off and is very cold, there are several reasons:

there is no shutdown command due to a malfunction of the thermostat sensors or relays;
“Super Freeze” mode is selected;
control board malfunction;
loss of compression in the unit;
a malfunction in any element of the heating circuit.

Modern electronically controlled refrigerators are complex. The best thing you can do is empty the chambers of food and call a specialist. Before doing this, you need to check the signs of malfunctions outlined in the instructions.

No Frost refrigerator is very cold

No Frost is considered a complex system for transferring cold from the evaporator to the chamber. The evaporator radiator is located behind the wall, there is also a fan that forcibly blows air from the chamber through the gaps between the cold tubes, taking away the cold. Cold air enters the chamber, and heated air, with moisture, approaches the evaporator, leaving frost on the tubes. When the compressor stops, the heating element periodically turns on, and the melted water is removed into the drain.

Why does a refrigerator with No Frost start to get very cold? The evaporator and the entire air cooling system are located in the freezer compartment. The cold chamber receives cold through an air duct with a damper. If the defrosting system of the evaporator tubes does not work, it becomes overgrown with ice, and heat transfer decreases.

There is not enough cold in the upper chamber, the compressor will work, cold air flows constantly. At this time, the freezer compartment in the refrigerator is very cold. Why? The compressor runs for a long time. Later the fan will stop, its blades will ice up or it will jam. The temperature will begin to rise in both chambers.

In the upper chamber, the temperature at No Frost may drop if the drainage hole is clogged and the water does not drain out. The refrigerator will be too cold. Droplets from the air will begin to condense on the walls and freeze, blown by cold air. The temperature in the positive chamber will drop to 0 0 C and below.

What to check first

First, it is necessary to carry out an external inspection of the device. Perhaps the faulty part can be removed and repaired yourself.

Checking settings

Pay attention to the position of the thermostat knob - normally it should be turned as follows:

Inspection of the door seal

The rubber on the unit door may wear out over time or be mechanically damaged. When cracks or ruptures appear on it, the tightness of the chambers is compromised, and this is evidenced by the following signs:

the upper chamber freezes too much - ice appears on the back wall and the food becomes frozen;
The freezer compartment becomes iced up, and a puddle of water forms in it due to the entry of warm air.

The seal can be replaced yourself. To do this you need:

remove the door from its hinges and lay it on a horizontal surface;
pry the elastic band around the perimeter with a flat screwdriver or knife and carefully separate it;
wash and dry the inner edge of the door;
take a new rubber band, lift the corner of the fixing frame and place the seal under it;
lay the seal around the entire perimeter;
put the door in place.

Identifying a clogged drain hole

The reason why the refrigerator gets very cold may be a clogged drainage hole. In this case, the evaporation, turning into condensation and flowing down the back wall of the refrigerator compartment, is not removed from it, but pours to the bottom and freezes. This leads to the fact that the unit begins to severely freeze the products located at the very bottom.

You can clean the drain hole using a wire, and after that you need to flush the drains with warm water, using, for example, a syringe.
