Correctly setting the climate zone inside the refrigerator compartment is a critical condition for long-term storage of food. Two-chamber models Beko equipped with modern control systems that allow the user to accurately set microclimate parameters. Incorrectly set values can lead to rapid spoilage of food or, conversely, to its freezing and loss of taste.
Owners are often faced with the need to change standard factory settings immediately after purchase or when the season changes. In the summer, when the ambient temperature in the kitchen is high, the compressor works more intensely, and adjustments may be required. In winter, the situation can be diametrically opposite, requiring less energy consumption.
Understanding the operating principles of your unit will help not only save on electricity, but also extend the life of the equipment. In this article we will analyze in detail the mechanical and electronic control systems, and also consider the nuances of the system No Frost. You will learn how to independently diagnose cooling problems and effectively eliminate them.
Principles of operation of the cooling system in Beko refrigerators
Two-chamber refrigerators Beko operate on the basis of a closed refrigerant circulation cycle. The compressor compresses freon gas, which is then condensed into liquid in a condenser, usually located on the rear wall. The cooled refrigerant enters the evaporator, where it boils and absorbs heat from the internal space of the chambers.
This process is controlled by a thermostat or an electronic module that reads data from temperature sensors. Depending on the model, adjustment can be done in steps or with an accuracy of up to a degree. Understanding this mechanism is important for an informed approach to settings.
The system No Frost, which is often found in models Beko, uses fans to force the circulation of cold air. This ensures uniform temperature distribution throughout the entire volume, eliminating the formation of an ice crust. However, such a system requires a special approach to placing products so as not to block the ventilation holes.
How does the freshness zone work?
Some Beko models have a separate zone with zero temperature or high humidity. In this compartment, cooling occurs more intensively than in the main chamber, which is ideal for storing meat, fish or fresh vegetables that require special conditions.
Mechanical control: setting the thermostat
In models with mechanical control, adjustment is carried out using a rotary switch located inside the refrigerator compartment. It is usually located on the top wall or side and is a disk with numbers from 1 to 5 (or 1 to 7). It is important to remember the main rule here: the the higher the numberthe lower the temperature inside.
Position "1" corresponds to minimum cooling, and the maximum value (for example, "5" or "Max") starts continuous operation of the compressor. The factory setting is usually in the middle position, which is optimal for most situations. If you have just loaded a large amount of food, you can temporarily increase the cooling.
⚠️ Attention: It is not recommended to constantly keep the control at the maximum value. This leads to increased wear on the compressor, increased energy consumption and possible freezing of products located at the back wall.
For precise adjustments, use the following algorithm:
- 🌡️ Turn the knob to the middle value and leave the refrigerator to operate for 5-6 hours without changes.
- 🥛 Place a glass of water in the center of the middle shelf and put a household thermometer there.
- ⏱️ After a few hours, check the readings: the optimal range is +2...+4°C.
- 🔄 If the temperature is higher, increase the value on the regulator; if lower, reduce it.
☑️ Checking the mechanical thermostat
Electronic control: setting via the Display panel
Modern two-chamber refrigerators Beko are often equipped with an electronic control panel located on the outside of the door or inside cameras. Such models allow you to set the temperature with an accuracy of 1 degree. Control is carried out by touch buttons or mechanical keys under the display.
To change parameters, you need to activate the setup mode, usually this is done by long pressing the button with the image of a thermometer or a snowflake. Once the numbers on the screen Display start flashing, you can change the values for the refrigerator or freezer compartment separately. This gives flexibility in cold distribution.
In some advanced models, a mode is available Eco Modethat automatically sets the temperature to +5°C in the refrigerator compartment and -18°C in the freezer. This is the optimal balance between food safety and energy efficiency. Switching between modes is often done using a button with the corresponding icon.
| Mode | HK temperature | MK temperature | Purpose |
|---|---|---|---|
| Standard | +4°C | -18°C | Daily storage |
| Eco | +5°C | -18°C | Energy saving |
| Max Cool | +2°C | -24°C | Fast cooling |
| Vacation | +10°C...+15°C | -18°C | Long absence |
Optimal temperature conditions for different products
Different groups of products require different storage conditions to maximize the preservation of their properties. Dairy products, meat and fish are sensitive to the slightest deviations from the norm. Vegetables and fruits, on the contrary, can spoil at too low a temperature, losing moisture and structure.
For meat and fish products, the ideal range is from 0°C to +2°C. That is why refrigerators Beko often have a bottom shelf or a special compartment where the temperature is always slightly lower than the average in the chamber. It is better to store open packages of ready-made dishes here.
It is better to store vegetables and fruits at a temperature of +4...+8°C in special boxes with humidity control. Too cold air can cause lettuce leaves to burn or bananas to brown. It is better to place milk and eggs on the middle shelves, avoiding the door, where the temperature fluctuates when opening.
Seasonal adjustment and external factors
Ambient temperature directly affects the operation of refrigeration equipment. In the summer, when the kitchen is hot, the compressor takes longer to dissipate the heat through the condenser. During such periods, an increase in internal temperature may occur, and manual adjustment of the settings will be required to increase cooling.
In winter, the situation changes. If the refrigerator is in an unheated room or near a window, the temperature difference can be critical. However, modern models Beko are designed to operate in a certain climate class indicated on the nameplate (usually from +10°C to +32°C or +43°C).
⚠️ Attention: Installing the refrigerator next to heating appliances or in direct sunlight is prohibited. This disrupts heat transfer and forces the equipment to work at its limit, which can lead to breakdown.
When seasonality changes, check the tightness of the door seals. Warm air entering through leaks causes the temperature sensors to send false signals to the control module. Regular cleaning of the rear condenser also helps maintain cooling efficiency year-round.
Diagnosing thermal problems
If you notice that food has begun to deteriorate faster than usual or, conversely, to freeze, this is a signal of a malfunction. The first step is to eliminate the human factor: check whether the door is tightly closed, whether the refrigerator is loaded with a jam that blocks the air flow.
A frequent problem is the failure of the temperature sensor (thermistor). In this case, the electronic module receives incorrect data and either does not turn on the compressor or runs it without stopping. The thermostat in mechanical models may also stick.
Pay attention to the following signs:
- ❄️ An ice coat forms on the back wall of the refrigerator compartment (a sign of problems with defrosting).
- 🔊 The compressor works continuously, without turning off for rest.
- 🌡️ The temperature in different corners of the chamber is very different (more than 3-4 degrees).
- 💡 The emergency temperature indicator is on or a sound signal is heard.
Frequent questions and answers (FAQ)
Why do food freeze at the back wall in the Beko refrigerator?
This can happen if the temperature regulator is set to the maximum value, or if food lies close to the back wall, blocking the exit of cold air. It is also possible that the drainage hole is clogged or the defrost system is malfunctioning.
What temperature should be set in the freezer for storage?
For long-term storage of frozen foods, the optimal temperature is -18°C or lower. In this mode, bacteria do not multiply, and the products retain their properties for up to 12 months. The fast freezing mode (-24°C) should only be used for a short time.
What does the flashing temperature indicator on the panel mean?
A flashing indicator usually signals that the temperature inside the chamber has risen above the permissible threshold. This may be due to prolonged defrosting, loading warm food or a malfunction. If the blinking does not stop after several hours of operation, diagnostics are required.
Is it possible to adjust the temperature separately in each chamber?
In two-chamber refrigerators Beko with two compressors or system Duo Cooling adjustment is carried out independently. In models with one compressor and one circuit, the cooling is often connected: changing the mode in one chamber can indirectly affect the other, although the electronics tries to minimize this influence.
