The refrigerator is very cold in the upper chamber: reasons and what to do

We carry out a visual inspection

Often, owners themselves become the reason that equipment fails. So, lovers of chilled drinks set the temperature regulator on manually controlled equipment to maximum in the hot season. It is important not to forget that no matter what the ambient temperature is, the temperature control knob should be in the middle with permissible deviations of one or two divisions. The same applies to models with an electronic control panel, such as Samsung or Indesit. You need to select the desired option for setting the temperatures inside the refrigerator compartment and set the temperature from +2 to +6 degrees.

Frozen refrigerator

Also, an inexperienced user can accidentally turn on the “Super Freeze” mode, when the temperature in the compartments drops significantly in a fairly short period of time. You can correct the situation by disabling this mode by pressing the desired button.

If the regulator is in the correct position, but the upper chamber is still covered with ice, you should pay attention:

on the integrity of the seal running along the edges of the door,
on the degree of cleanliness of the drainage channel.

Why the refrigerator gets very cold: the main reasons

If you have checked the first causes of the problem, but have not identified why your household refrigerator freezes so much, you need to familiarize yourself with common breakdowns. Some of them can be fixed on your own, but in most cases it is better to call a qualified technician.

Broken thermostat or air sensor

The thermostat performs the function of maintaining a certain temperature in the refrigerator compartment.
When the compressor is turned on when the set cold values are reached, the thermostat turns off the motor. When the air temperature in the chamber rises, it transmits a signal to the engine to begin cooling the internal space. A broken or intermittently functioning part leads to continuous operation of the motor-compressor. The part activates the lowest possible temperature mode. Thermostat failures occur as a result of:

normal wear and tear;
exposure to large quantities of moisture;
due to mechanical damage.

A faulty thermostat cannot be repaired, only replaced. It is not recommended to repair a complex spare part yourself - contact a service center.

The air sensor is present in modern models of refrigerators with the “No Frost” system. The part evaluates the air temperature in the chamber and sends data to the control module. Its breakdown provokes system failures - the compressor works without stopping. If the sensor is faulty, it must be replaced with a new one.

Freon leak

If the refrigerator begins to work incorrectly and starts to freeze very much, you need to check the cooling system:

freon leakage provokes a decrease in pressure, and to maintain low temperatures the engine runs continuously, compensating for the imbalance;
The refrigerant can evaporate even through small holes and it is almost impossible to find leakage areas on your own.

Only an experienced technician can fix the problem, who will identify the damaged areas, seal the cracks and refill the freon.

Clogged capillary system

Blockages in the capillary pipes lead to disruptions in the entire operation of the equipment.
Under normal conditions, the refrigerant circulates evenly between the refrigerator and freezer compartments. If the pipes are clogged, the compressor begins to work actively. In this case, the freezer will thaw, and the refrigerator compartment will work intensively. Why is your refrigerator very cold? Capillary tubes can become clogged for the following reasons:

violations of technical conditions;
lack of periodic cleaning;
burning of engine oil.

You can clean the system yourself by syringing the capillary tube. If the blockage does not go away, you need to call a professional.

Shift valve failure

If you still haven’t found the reason why food freezes too much in a household refrigerator, then the last option is a malfunction of the switch valve.
This part provides cooling switching between the refrigerator compartment and freezer. The problem leads to freezing of ready-made dishes. The solution to the problem is to replace the component. It is better to entrust the work to a specialist. Important! Only single-compressor models are equipped with a switching valve. If your kitchen refrigerator gets very cold, you need to know what to do in such situations? Turn it off with the button from the outlet and visually determine the type of breakdown.

Door seal wear

Diagnosing the wear of the door seal is not difficult - just carefully inspect the door from the inside. If for any reason it comes unstuck or ruptures, the seal of the refrigeration compartment is broken and heat leaks inside. To normalize the temperature, the refrigerator begins to produce cold more intensely, which leads to the food freezing.

Door seal

Seal wear is common on the LG Electronics GC-B247JEUV. Many owners of these units notice that the upper chamber freezes food very much. In addition, it is observed:

water on the floor around,
darkening and rapid wilting of fresh vegetables and fruits,
quick souring of ready-made dishes.

If the refrigerator gets very cold because the seal is worn out, it must be replaced with a new one without delaying the repair. Working in constant intensive mode can damage the compressor, both in the above LG Electronics GC-B247JEUV and in other models, for example, Samsung or Indesit. Repairing this part will be much more difficult and expensive.

The refrigerator is very cold: what to check first

Breakdowns of refrigeration devices occur due to improper installation, careless operation, frequent power surges, and natural wear and tear of parts.
If the equipment freezes food, this does not mean that the refrigerator has suffered serious malfunctions. Trivial errors and system failures can lead to increased temperatures. First of all, you need to inspect the equipment and check its settings.

Checking settings

If the refrigerator gets very cold under optimal operating conditions, you need to check the appliance settings.
In standard models equipped with a thermostat, the optimal temperature inside the cooling chamber is about +6 °C. The minimum threshold should not reach below 0. In such conditions, products retain their beneficial properties and do not freeze. The temperature in the compartments is controlled by a mechanical switch or control panel. See what mode is set and enter other settings. Models with the super freeze option can dramatically lower the temperature of both compartments. If you have a small number of products and the function is active, just turn it off.

Inspection of the door seal

The rubber seal on the door ensures the tightness of the compartments. Over time, it wears out or may become unusable due to mechanical damage. In this case, heat from outside enters the chamber. To maintain the storage temperature and compensate for the penetrating heat, the refrigerator will begin to intensively produce cold.

The following signs indicate wear of the seal:

darkening of fresh fruits and vegetables;
formation of an ice crust on soups and side dishes;
the appearance of water under the refrigerator body;
formation of a snow “coat” on the walls of the chambers;
severe ice formation in the freezer compartment;
presence of leaks near the door.

To fix the problem, you need to replace the rubber seal.

Don't forget to check the seal

Identifying a clogged drain hole

When food or food freezes heavily in the refrigerator, there is a risk of clogging the drainage system. Condensation and water are not removed, so they freeze. The result will be failures of the upper part of the cooling compartment. The drainage system should be periodically cleaned by douching with warm water. Complex stains can be removed with a solution of soda or citric acid. Important! Blocked drainage leads to the proliferation and spread of fungus and unpleasant odors.

Drain channel clogged

A drainage channel for removing excess moisture is available in every refrigerator. And often, along with the accumulated condensate, particles of products get into it, which clog it. Instead of draining into the channel, excess liquid accumulates under the lower vegetable trays, where it forms a dirty puddle that, along with cycles, freezes and thaws again. In addition to the fact that the vegetables and fruits in the tray freeze together with it, dirty water becomes a breeding ground for mold and bacteria, which spread throughout all compartments, spoiling other products.

Drainage channel

You can solve the problem of a clogged drain pipe yourself in three ways:

Clean the drainage hole with warm water filled into a rubber bulb.
Blow it out using a bicycle tire inflation pump or a car pump. You can also do such “blows” once a month for prevention.
Push through the clog with a piece of thin wire or wire.

You can check whether the blockage has been cleared by pouring a little water into the chute located at the drain. If there is no blockage, the water will quickly go down.

Reasons for increased cold formation

Some malfunctions in the operation of the refrigerator can be eliminated on your own, but in difficult situations you will have to pay a technician to diagnose and repair the equipment. Often the source of the problem is the following faults:

freon leak or blood clot in capillary tubes;
wear of the sealing rubber;
clogged drainage system;
breakdown of the thermostat or air sensor;
valve sticking in a single-compressor unit.

Problems that experts fix

If the refrigerator begins to freeze very much, and you were unable to correct the situation yourself, you need to call a repairman. A service center employee will most likely diagnose the following reasons why the upper camera began to work poorly:

The Samsung refrigerator often gets very cold due to a broken thermostat. The part responsible for maintaining the required temperature conditions fails due to moisture getting on the contacts and mechanical damage.
Both Samsung and any other refrigerator will not be able to work properly without the required amount of freon. When gas leaks from the system, the compressor begins to work continuously, raising the temperature in the upper chamber too low.
Indesit, and other modern models, are equipped with an electronically controlled “No Frost” system, which allows you not to defrost the refrigerator. If the air sensors fail, the control module receives incorrect temperature data, causing the compressor to work harder.
It happens that the freezer and cold chambers “swap places” and the food in the freezer is not frozen, but on the contrary, the upper chamber is covered with ice. In this situation, the culprit is a broken switching valve, which is responsible for the cooling functions between the compartments.

Refrigerator repair

It is important not to delay in diagnosing a malfunction in the refrigerator. Any ignored errors can result in expensive repairs or treatment that will lead to poisoning from spoiled food products.

Causes of malfunction

Experts identify six reasons for the malfunction. Each of them can damage a new or used refrigerator and spoil the food stored in it. Let's look at each version of the breakdown:

incorrect settings of the thermostat lever (this has already been mentioned above; the owner could accidentally set the wrong mode or set the temperature in the chamber too low);
damage to the sealing gasket on the refrigerator door (signs of such a malfunction may include an unfrozen puddle near the door and ice on the chamber wall; you can restore the integrity of the seal yourself; even a person without special skills can handle this);
clogged drainage holes (under the boxes for vegetables and fruits there are special drainages, which sometimes tend to become clogged, then condensed water, flowing down the back wall, enters the drainage and freezes there, simultaneously freezing nearby products; the problem can be dealt with by cleaning the drainage system douching);
freon leak (manifested due to microcracks or blood clots found in the cooling system; an experienced technician will be able to quickly and accurately fix the problem);
failure of the thermostat (you need to ring it with a special tester and, if it does not respond, you will have to replace it with a new one; a specialist who works with similar household appliances can handle the problem);
sticking of the control valve (it should regulate the switching of modes, but this does not happen, the failure of the valve is to blame, you will need to find it and replace it with a new, working valve).

Important! If a person is not confident that he is able to cope with a breakdown on his own, it is better to contact a special service staffed by experienced craftsmen. Otherwise, self-repair may result in an even more complex breakdown.

The indicated recommendations and causes of malfunctions are suitable for almost all models and companies that produce refrigerators. The only exceptions can be ultra-modern models with a large number of third-party modes and innovative cooling systems.

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.

IMPORTANT: Myths and fairy tales

There are many articles on the Internet that give advice from incompetent people. They can name the following reasons why the main compartment of the refrigerator does not work:

Doors do not close tightly;
The seal is worn out;
It's too hot in the apartment;
Do you use the main compartment often?
Place hot food in the refrigerator.

Indeed, all this leads to improper operation of the equipment. But for the main camera not to work... There must be a good reason. It’s not like you didn’t close the door tightly or put a pot of warm soup in the refrigerator. And now more details.

Problems with doors and seals

Let's say the gap between the door (seal) and the refrigerator body is 1 cm. Then the main chamber will cool, but the compressor will have difficulty. It will turn on frequently, or work constantly. But the refrigerator will maintain the temperature.

High temperature in the apartment

There is an opinion that in hot weather the refrigerator does not cope with its work. In fact, manufacturers make equipment with a power reserve. Even if it’s +35 in your apartment, the refrigerator will work. There may be excessive consumption of electricity, but it will cope with its task.

Frequent use

Any refrigerator manufacturer relies on the doors to open and close. This is normal operation of this type of technology. Yes, the more often you open the main chamber of the refrigerator, the greater the heat influx. But this will only lead to the following:

The compressor will work more intensely;
There will be periodic temperature changes in the upper chamber;
The electricity consumption of the refrigerator will increase.

Hot food in the refrigerator

Indeed, when you place hot food in the refrigerator, the load on the compressor increases. He won't always be able to cope with it. The chamber may warm up and it will seem that the refrigerator is not cooling. But this is temporary; soon the compartment will cool down to the optimal temperature.
