The issue of correctly setting the temperature is of concern to every owner of a refrigeration unit equipment, because the safety of products and the service life of equipment directly depend on this. Many users, when purchasing brand equipment for the first time Beko, wonder what number they need to turn the knob to in order to maintain an ideal microclimate inside. The answer is not as clear as it might seem at first glance, since it depends on many factors: from the time of year to the degree of workload of the cameras.
The average value recommended by manufacturers for everyday use is the position of the regulator in the middle of the scale. Typically, mechanical thermostats have a range from 1 to 5 or 1 to 7, with a lower value indicating a higher temperature and a higher value indicating a lower temperature. However, blindly following the instructions “set to 3” may not give the desired result if the room is hot or the refrigerator is filled to capacity with food.
It is important to understand that number on the thermostat is not degrees Celsius, but the conditional power of the compressor. The higher the value, the more intensively the motor-compressor works, cooling the chambers more strongly. Incorrect settings can lead to food spoilage due to insufficient cold, as well as to the formation of an ice crust and excessive energy consumption due to excessive cooling.
Interpretation of the Beko thermostat scale
Mechanical temperature controllers in refrigerators Beko represent a rotary disk with divisions. Understanding the operating logic of this node is the key to proper management. On the control panel you will see numbers that often range from Min (or 1) to Max (or 5-7). It is important to remember: number 1 is the minimum cooling mode (the warmest temperature inside), and the maximum number (for example, 5 or 7) is the maximum freezing mode.
Between these extreme values there is a “golden mean”. If you set the regulator to minimum, the compressor turns on less often and runs for less time, maintaining a temperature of about +6...+8°C in the main chamber. When switching to maximum, the equipment tends to reach values of about 0...+2°C, forcing the motor to work almost non-stop.
In some modern models with electronic control, the scale can be replaced with a digital display, where you set specific degrees. But in classic mechanical models, which are the most popular due to their reliability, you need to focus specifically on conventional units of cooling power.
⚠️ Attention: Never set the regulator to the maximum value (Max) immediately after turning on the empty refrigerator. This can lead to rapid freezing of the evaporator and increased load on the compressor in the first hours of operation.
For clarity, let's look at how the approximate ratio of numbers affects the temperature regime inside the main chamber:
| Regulator position | Conventional value | Approximate t° in the chamber | Compressor operating mode |
|---|---|---|---|
| 1 (Min) | Minimum cooling | +7...+9°C | Short cycles, long pauses |
| 3 (Average) | Normal mode | +4...+5°C | Standard on/off cycles |
| 5 (Max) | Maximum cooling | +1...+2°C | Long operation, rare pauses |
Recommended values for different seasons
One of the most common mistakes made by users is ignoring the seasonal factor. The temperature in the room where the refrigerator is located directly affects heat transfer. In the summer, when the apartment is hot, the thermal conductivity of the walls increases, and the equipment requires more effort to maintain the cold. In winter, the situation changes: heated rooms can be dry and warm, but if the refrigerator is located on an unheated loggia or in a corridor with a draft, the settings need to be adjusted.
In the summer, when the ambient temperature reaches +25...+30°C, it is recommended to shift the regulator towards higher values. This does not mean that you need to set the maximum, but a shift from “3” to “4” will help compensate for heat gain. And vice versa, in winter, when the batteries are operating at full capacity or, conversely, the room is cool, the load on the cooling system changes.
However, it is also worth considering humidity. In wet weather with high settings, more intense moisture formation may occur. Therefore optimal figure is always a balance between the temperature in the room and the desired result inside the refrigerator.
Seasonal recommendations can be reduced to the following rules:
- 🌞 Summer: When the temperature in the kitchen is above +25°C, move the regulator closer to the maximum values (4-5 out of 7), but make sure that the products on the shelves near the wall do not freeze.
- 🍂 Off-season: Spring and autumn, when indoors about +20...+22°C, the ideal is the middle position (3 out of 5 or 4 out of 7).
- ❄️ Winter: If the room is cool (+18°C and below), you can reduce the regulator value (2-3), since it will be easier for the refrigerator to cool the chambers.
⚠️ Attention: If your refrigerator is equipped with a No Frostsystem, seasonal fluctuations affect it less due to a more advanced heat removal system, but the basic principles of setting the thermostat remain relevant.
The influence of chamber loading on the settings
Refrigerator fullness - this is essentially its thermal inertia. An empty refrigerator cools quickly, but heats up just as quickly when the door is opened. A unit completely filled with food requires more time for initial cooling, but maintains the temperature better. This leads to a logical conclusion: the thermostat settings should depend on how tightly the shelves are packed.
If you just bought a refrigerator or defrosted it and it is completely empty, you should not immediately turn the regulator to maximum. In an empty chamber, cold air circulates freely, and a powerful operating mode can quickly lead to dry air and the formation of excess frost on the evaporator. In this case, minimum or average values are sufficient.
The situation changes dramatically when you return from large-scale shopping and load the chambers with warm products. At this moment heat capacity the content is great. To cool a large volume of food to a safe +4°C, the system requires increased power. Temporarily increasing the value on the thermostat will help you pass the critical stage faster.
☑️ Checking the refrigerator load
In addition, it is important to consider the location of the products:
- 🥩 Meat and fish: If there are a lot of perishable foods on the bottom shelf, make sure that the temperature there is sufficient (closer to 0...+2°C), you may need to add 1 division on the regulator.
- 🥬 Vegetables and fruits: For them, it is critical not to freeze the cells. If the regulator is set to maximum, vegetables in the lower drawers may suffer from cold coming from above or from the back wall.
- 🍼 Children's food: Requires strict adherence to the temperature regime, therefore, when fully loaded with such products, control of the thermostat setting becomes a priority.
Specifics of operation of the No Frost system
Refrigerators Beko with the system No Frost (or Full No Frost) are designed differently than classic models with a crying evaporator. In them, cold air is forced to circulate through the chambers using a fan. This means that the temperature inside is distributed more evenly, but the reaction to changing the thermostat settings can be faster and more noticeable.
In models with No Frost The temperature sensor is often located not at the back wall, but in the air circulation area. Therefore, when you change the position of the knob, the system responds faster to the changed parameters. However, there is a caveat: due to active air circulation, products on open shelves can be blown out and dry faster if the temperature is set too low.
Forced circulation systems have the following feature: even at medium settings (3 out of 5), they provide very effective cooling. Therefore, users who are accustomed to old Soviet refrigerators may mistakenly assume that the appliance “does not freeze” and turn the regulator all the way. This should not be done.
Why can it be colder at the rear wall in No Frost?
In systems with air circulation, the cold flow comes out of the channel on the rear wall. If you place food close to the vent, it may freeze, even if the thermostat is set to low. Always leave a gap for circulation.
Optimal setting for Beko No Frost:
- 🌡️ Standard: Keep the regulator in position "3" (for a scale up to 5) or "4" (for a scale up to 7). This is enough for most tasks.
- 💨 Ventilation: Remember that correct setting of the thermostat in such models is useless if the ventilation holes inside the chamber are clogged.
- 🔊 Noise: When set to maximum cooling, the fan and the compressor will work more intensely, which can increase the noise level.
Diagnostics: is the refrigerator configured correctly
How do you understand that you have guessed the number correctly and the equipment is operating normally? There are several indirect signs that will help make a diagnosis without a thermometer, although using a separate thermometer gives 100% accuracy. First of all, pay attention to the frequency of operation of the compressor.
In normal mode, the refrigerator should operate cyclically: the cooling period is replaced by a rest period. If the motor hums almost without interruption, and inside the refrigerator there is a “coat” of frost or the food at the back wall has turned into an ice ball, you have clearly gone too far with the settings. The figure needs to be reduced.
The opposite situation: the compressor turns on rarely, it works for a short time, but it’s warm inside the refrigerator, the milk quickly sours, and condensation appears on the walls (in models without No Frost). This is a signal that the cooling power (current figure on the regulator) is not enough to compensate for the heat inflow. The value needs to be increased.
⚠️ Attention: If, at any position of the regulator (even at maximum), the refrigerator does not cool, or, conversely, everything freezes to zero at the minimum setting - the problem is not in the number on the thermostat, but in a malfunction (freon leak, thermostat failure or capillary blockage).
Signs of correct setting:
- ✅ Products: Chilled products are not covered with frost, but are not warm to the touch either.
- ✅ Walls: In a chamber with a “crying” wall, moisture evenly flows into the gutter without turning into snowdrifts.
- ✅ Mode: The compressor operates with clear rest intervals, amounting to approximately 30-50% of the total cycle time.
Frequent errors during adjustment
Many users make typical mistakes when trying to “adjust” the refrigerator. One of the most common is an attempt to compensate for the malfunction with settings. If the rubber seal in the refrigerator is loose or the condenser at the back is dirty, no number on the thermostat will help effectively cool the food, but will only lead to breakdown of the compressor due to overload.
Another mistake is a sudden change in values. Do not turn the thermostat knob immediately from “1” to “5”. The mechanics and coolant need time to stabilize. After each change in the position of the regulator, you must wait several hours (preferably a day) before drawing conclusions about the result.
The location of the refrigerator is also often ignored. If the equipment is standing close to the wall, heat exchange is disrupted. The user sees that there is not enough cold, and adds power (turns it to a higher number). As a result, the compressor burns out, although you just needed to move the refrigerator 5-10 cm from the wall.
The myth about the number 0
Some regulators have a position 0 or Off. This is not "minimum cold", this is a complete shutdown of the refrigerator. The compressor will not start until you change the control to 1 or higher.
List of actions to avoid:
- 🚫 Constant twisting: Do not change the settings every day. Stability is more important than constant experiments.
- 🚫 Ignoring (Instructions): The manual for a specific model Beko may contain unique recommendations that differ from the general rules.
- 🚫 Maximum forever: Do not keep the refrigerator constantly at maximum "just in case." This reduces the life of the equipment.
Technical nuances and maintenance
Adjusting the temperature is only part of fridge care. In order for the settings you choose to work effectively, you need to monitor the technical condition of the unit. A condenser clogged with dust (grid at the back) drastically reduces the efficiency of heat transfer. In this case, even by turning the thermostat to the maximum, you will not get the desired cold, and the motor will wear out.
It is also important to check the tightness of the door. If the magnetic seal is loose or dirty, warm air constantly flows inside. The temperature sensor detects the heating and gives a command to work harder. As a result, you are forced to turn the regulator to large values, consuming excess electricity.
In models with mechanical control, the thermostat itself may become loose or oxidize over time. If you notice that when you turn the handle there is no characteristic click or the movement has become too free, this unit may need to be replaced. But this is already a task for the service center.
How often do you need to defrost a Beko refrigerator if the settings are incorrect?
If you keep the refrigerator at high thermostat settings (4-5 out of 5) in high humidity conditions, ice in the freezer (even in the No Frost system, snow may appear in the freezer) will grow faster. It is recommended to carry out preventive defrosting once every 6-12 months, or when the frost layer exceeds 5 mm.
Why does the temperature not change immediately after changing the setting?
The refrigerant and oil in the system require time to circulate and stabilize the pressure. In addition, the large volume of food and the walls of the refrigerator have a high heat capacity. It may take from 6 to 24 hours for the temperature to completely stabilize after turning the knob.
Can I use a thermometer for adjustments?
Yes, this is the most accurate way. Place a glass of water on the middle shelf, lower a household thermometer there and leave for several hours. Depending on the readings, adjust the position of the regulator: above 5°C - add a number, below 2°C - decrease it.
Does the voltage in the network affect the operation of the thermostat?
Strong voltage surges can affect the operation of the compressor and the start relay, but the mechanical thermostat itself does not depend on voltage. However, at low voltage, the compressor may not start or operate unstably, which will create the illusion of incorrect temperature settings.
