Sometimes a paradoxical but vital situation arises: the food in the refrigerator begins to freeze, turning into ice blocks, although the device should only cool. Vegetables lose their elasticity, milk crystallizes, and ready-made dishes become unfit for consumption. This is a sure sign that compressor operating mode is configured for too intense cooling.
You do not have to call a technician to solve this problem, since in most cases temperature adjustment produced independently by the user. Modern and old models have different control mechanisms, but the principle of operation remains the same: it is necessary to shift dew point and change the engine shutdown threshold.
In this article we will look at how to safely and effectively raise the temperature to keep food fresh without the risk of spoilage from cold. The optimal temperature for storing most products in the main chamber is from +2°C to +5°C.
Determining the cause of excessive cooling
Before you grab the regulators, it is worth understanding why it became too cold in the chamber. Often the culprit is improper placement of products. If you tightly press the shelves against the back wall where evaporatoris located, cold air does not circulate evenly, creating local freezing zones.
Another common reason is thermostat malfunction or temperature sensor. If this element is stuck in the maximum cold position, the compressor will run non-stop. In models with No Frost the problem may lie in clogged air channels, which causes a cold stream to blow directly onto the food.
⚠️ Attention: If you notice that a thick layer of ice has formed on the back wall of the chamber, this may indicate not only high temperature, but also problems with the defrost system. In this case, simple adjustment may not help.
It is also worth checking tightness of the seal. Paradoxically, if the door does not close tightly, the compressor tries to compensate for the heat from the outside and works for wear, sometimes causing failures in cooling cycle and unpredictable temperature jumps.
Adjusting the mechanical thermostat
In classic models of refrigerators, such as Atlant, Biryusa or old Indesit, control is carried out using a mechanical handle. It is usually located inside the camera, on the top panel or side wall. The scale can be numbered from 1 to 7 or marked with the words Min and Max.
It is important not to get confused here: the number 7 (or Max) means maximum cooling, that is, the lowest temperature. To raise the degrees, you need to turn the knob towards a lower value. Smooth movement The control counterclockwise will reduce the intensity of the compressor.
Do not expect instant results. Thermostat it takes time to react and stabilize the climate inside the chamber. Typically the process takes from 4 to 8 hours, depending on the volume of the chamber and the number of products.
If your model is equipped with a separate one handle for the freezer, remember that it does not affect the main camera in single-circuit systems. In dual-circuit models (two-compressor), the adjustment occurs independently, which gives more flexibility in setting.
Setting up electronic control
Modern units from LG, Samsung, Bosch i Haier equipped with electronic control panels. Here the adjustment is made with an accuracy of a degree. You need to find a button or touch zone with a designation Temp, Fridge or an image of a snowflake.
Press the button several times until the current value lights up on the display. Using the navigation arrows or the +button, increase the numeric value. For example, if set +1°C, change it to +4°C or +5°C. Digital controller immediately send a signal to change the compressor operating mode.
In some models with the function Smart Cooling or Eco Mode manual setting may be blocked. In this case, first disable the automatic mode by pressing the corresponding button, and only then proceed to manual temperature calibration.
Hidden button combinations
In some Samsung models, to unlock the control panel (Child Lock), you need to simultaneously hold down two buttons for 3 seconds. Usually these are the "Freezer" and "Fridge" buttons or a special button with a lock.
Pay attention to the indicators. If after setting the temperature turns on alarm symbol or flashes, this means that the system has not yet reached the set parameters. This is a normal reaction of electronics.
Setting specifics for popular brands
Different manufacturers use unique algorithms and interfaces. Knowing the characteristics of your brand will help you avoid mistakes. Below is a table with guidelines for popular brands.
| Brand | Control type | How to raise the temperature | Nuances |
|---|---|---|---|
| Indesit | Mechanics / Electronics | Decrease the number on the scale (1-5) | Often there is no display, a guide by the light bulbs |
| Samsung | Sensor | Fridge button -> increase the value | There is a "Power Cool" mode that you need disable |
| LG | Sensor / Buttons | Fridge button -> cycle up to +5°C | Models with Smart Diagnosis can reset settings |
| Bosch | Wheel / Sensor | Turn left or minus button | High precision sensors, fast response |
| Atlant | Mechanics | Rotate counterclockwise | Scale from 1 to 7, where 1 is the warmest |
When setting electronic panels be careful: in some models Bosch i Siemens to enter the settings menu you need to hold the button for several seconds. Accidental pressing can activate the Super Freezemode, which will have the opposite effect.
If you have a model with freshness zone (Zero Zone), remember that the temperature there is always around 0°C. It is not worth raising the general temperature for the sake of this zone; it is better simply not to store products that require heat there.
☑️ Check before adjustment
The influence of loading and placing products
Often the problem lies not in the settings, but in volume how you store food. If shelves are packed to capacity, especially at the back, cold air cannot circulate. In systems No Frost this is critical, since the cold is forced by the fan.
Try to leave a gap of 2-3 centimeters between the products and back wall. This will ensure proper air circulation. If food is placed close to air ducts, it will freeze, even if the thermostat is set correctly.
Use containers. Plastic containers create a buffer zone, protecting food from direct exposure to cold air. This is especially true for vegetables and fruitsthat are sensitive to temperature changes.
⚠️ Attention: Never put hot or warm foods in the refrigerator. This causes a sharp jump in the load on the compressor and can throw off the readings, causing the system to work incorrectly. Temperature sensors Check them regularly. Over time, the bags may move and block the air supply channels. A simple revision of the contents often solves the problem of local freezing. temperature sensors, causing the system to work incorrectly.

Technical faults and when a technician is needed
If adjusting the thermostat and correct placement of products did not help, perhaps we are talking about technical failure. The most common reason is failure of the thermostat. It may “stick” in the “On” position, forcing the compressor to work continuously.
Another option is refrigerant leakage (freon). Although usually the temperature rises during a leak, in some phases or in the event of a malfunction capillary tube the system may not operate correctly, leading to freezing of the evaporator and subsequent sharp cold during defrosting.
It is also worth checking fan in No Frost systems. If it works intermittently or its blades are damaged, the distribution of cold is disrupted. In some cases, replacement is required control module, which sends incorrect signals to the actuators.
Do not try to disassemble foamed parts of the case or interfere with the piping system yourself. This can lead to complete failure of the unit and loss of warranty.
Prevention and proper care
To avoid problems with temperature conditions in the future, regularly carry out preventative defrosting (if the model is not No Frost). The accumulation of ice on the evaporator impairs heat transfer and interferes with the operation of the sensors.
Wipe sealing bands with a damp cloth. Dirt and crumbs prevent the door from sealing tightly, causing the compressor to work harder. Once every six months, check the cleanliness of of the condenser the back of the refrigerator.
Monitor the condition of the food. If you notice that the milk begins to freeze at the wall, but normally at the door, this is a signal that air circulation the settings are broken or require a slight adjustment.
Why is it too cold in the refrigerator after defrosting?
Immediately After defrosting, the thermostat may not have time to warm up to operating temperature, and the compressor will work longer than usual to gain cold. This is temporary. If the cold persists for more than a day, check the settings.
Can I use a thermometer to check?
Yes, this is the best way to control. Place a glass of water on the middle shelf, lower a household thermometer there and leave for 2-3 hours. This will give an accurate result, unlike built-in sensors that can lie.
Does the temperature in the room affect the operation of the refrigerator?
Yes, if the room is very cold (below +10°C), the refrigerator may not work correctly or may not turn on at all. If it is too hot, the compressor will work hard, trying to cool the chamber, which can lead to freezing of products due to failures in the cycle.
What to do if there is no temperature regulator?
In the simplest and oldest models there may be no regulator at all. In this case, the only way to raise the temperature is to provide an influx of warm air (open the door slightly for a short time) or install an external thermostat (requires the skills of an electrician).
How often do you need to change the settings?
Ideally - never, if the operating conditions do not change. However, it is recommended to adjust the temperature when the season changes (you can set it a little colder in summer, warmer in winter) or when the degree of loading of the refrigerator with food changes.
