Users of household appliances often encounter a misunderstanding of the principles of operation of mechanical thermostats, especially when there are unusual symbols on the scale. Owners of Turkish brand refrigerators Beko are no exception, especially if numbers starting from zero are visible on the regulator. Standard logic dictates that “0” should mean a complete absence of cold, but in the context of climate control inside the chamber, this rule works differently and requires careful study of the instructions.
Incorrect interpretation of the position of the thermostat knob can lead to spoilage of food or, conversely, to deep freezing, which is especially critical for fresh vegetables and fruits. In this article we will look in detail at exactly how temperature control works in refrigerators Beko, what the “0” position means and why it should be avoided in normal operation. Understanding these nuances will help extend the life of the compressor and keep your supplies fresh.
It is important to immediately note that the control system may differ depending on the type of control: a mechanical rotary regulator or an electronic panel with a display. Mechanical thermostat most often found in budget and mid-range models, and it is on its scale that you can find a mysterious scale from 0 to 5 or 0 to Max. Let's figure out how to correctly interpret these values for effective cooling.
Deciphering the thermostat scale: what the numbers mean
The main misconception of users is that they perceive the numbers on the thermostat handle as degrees Celsius. This is not true. The numbers from 1 to 5 (or up to 7 in some models) indicate work intensity the compressor, and not the specific temperature inside the chamber. The higher the number, the colder it will be inside the refrigerator compartment, since the compressor will work longer and more often.
The “0” position deserves special attention. On the thermostats of most mechanically controlled refrigerators, the number “0” means “Off” or “Stop” mode. In this position, the electrical circuit supplying power to the compressor opens, and the temperature inside begins to gradually rise to room temperature. This is not a minimum cooling mode, but a complete shutdown of the function. Beko with mechanical control, the number “0” means “Off” or “Stop” mode. In this position, the electrical circuit supplying power to the compressor is interrupted. The refrigerator stops cooling, and the temperature inside begins to gradually rise to room temperature. This is not a minimum cooling mode, but a complete shutdown of the function.
If you set the knob to “0” and heard a click, but the compressor did not start after 15-20 minutes, do not panic and think about a breakdown. This is the normal behavior of the device. To resume operation, turn the knob to position “1” or higher. Some models may also have a separate power button next to the regulator, but in the classic scheme, “0” on the scale is a switch.
⚠️ Attention: Long-term storage of products with the regulator position at “0” will lead to their damage. Use this mode only for defrosting or when leaving for a long time, having first emptied the chambers of perishable food.
The range of values is usually as follows:
- 🌡️ 0 — The compressor is turned off, no cooling is performed.
- ❄️ 1 — Minimum cooling mode (the temperature inside is closer to +8..+10°C).
- 🧊 3 — Medium, recommended mode (about +4..+5°C).
- 🌨️ Max / 5-7 — Maximum cooling (temperature can drop to 0..+2°C, risk of freezing food at the back wall).
Mode “0” and “Min”: what is important difference
Often users confuse the minimum operating mode and the shutdown mode. On the thermostat scale Beko the minimum cooling is indicated by the number “1” (or sometimes “Min” if there are no numbers). In this mode, the compressor turns on rarely, maintaining the temperature at the upper limit of the permissible range. This is useful in winter when the room is cool, or if you are storing food that does not require extreme cold, such as some types of cheese or fruit.
Position "0", as already mentioned, is a complete stop. However, in some older or specific modifications of mechanical thermostats, the logic may be inverted, although for a brand Beko this is an extremely rare exception. In the vast majority of cases, the algorithm is the same: 0 = OFF, 1 = Min Cooling, Max = Max Cooling. If your refrigerator stops freezing after setting the knob to zero, then the system is working properly, executing the stop command.
There is also a nuance with the “thermal relay”. When moving the knob from position “0” to position “1” or higher, the compressor may not start instantly, but with a delay of several minutes. This is a safety mechanism that prevents frequent engine starts. If, after moving the handle to the working position, the refrigerator is silent for more than 20-30 minutes, it is worth checking the network connection and the presence of voltage in the socket.
How to set the temperature correctly: step-by-step instructions
In order for your refrigerator Beko to work efficiently and economically, you need to set the thermostat correctly. The optimal value for everyday use is considered to be between “2” and “3” (or the middle of the scale if there are no numbers). This provides a temperature of about +4°C, ideal for storing most foods.
The setup process is as follows:
- Find the thermostat. In refrigerators Beko it is usually located inside the refrigerator compartment, on the right or left wall, or on the ceiling of the chamber.
- Assess the current situation. If the food freezes at the back wall, reduce the value (turn counterclockwise).
- If the food spoils quickly or the chamber is warm, increase the value (turn clockwise).
- After each change in the position of the knob, wait 2-3 hours (or better yet, a day) for the temperature to stabilize before the next adjustment.
☑️ Checking the temperature setting
In the summer, when it is hot in the kitchen, it may be necessary to increase the cooling (move closer to Max), and winter, when the heating is running or, conversely, when ventilating, the mode should be adjusted towards the minimum.
| Handle position | Operating mode | Approximate t°C inside | When to use |
|---|---|---|---|
| 0 | Off | Room | Defrosting, washing, long absence |
| 1 (Min) | Weak cooling | +7..+9°C | Winter, fruit storage, partial load |
| 3 (Average) | Normal mode | +3..+5°C | Daily use (recommended) |
| Max (5-7) | Turbo cooling | 0..+2°C | Fast cooling of a large volume of products |
Adjustment features in models with NoFrost and electronics
In more modern models Beko with a system NoFrost and electronic control, the number scale may be absent. Instead of a rotary knob, a keypad or touch display is used here, where the temperature is set directly in degrees Celsius. In such refrigerators, the concept of “digits from 0” loses its mechanical meaning, since you set a specific target parameter.
However, even in electronic models there may be a “0” function, but it is often implemented as a separate power button or “Vacation” mode. In the "Vacation" mode (often indicated by a palm tree icon), the refrigerator compartment can turn off (the temperature rises to +10..+15°C), while the freezer continues to operate. This saves energy and prevents odors while you're away.
If you have a model with a display and you see numbers or symbols flashing, this may indicate an error or setup process. In such cases, a “0” on the display may mean that the sensor is not reading the temperature, or that the initial startup process is in progress. Always check the instructions for the specific model, since the software of the controllers Beko may vary depending on the year of manufacture.
Why is there no knob in the electronics?
In electronic models, the thermostat is replaced with a temperature sensor and an electronic control module. The compressor is turned on not by mechanical opening of the contacts, but by a signal from the processor, which makes it possible to more accurately maintain the temperature and implement complex algorithms, for example, quick freezing.
Typical problems and their solutions during setup
Often users are faced with a situation where seemingly correct settings do not give the expected result. For example, the refrigerator hums, but does not cool, or, conversely, everything turns to ice. If the regulator is not set to “0”, and the product deteriorates, perhaps the problem is not in the settings, but in thermostat malfunctions or a refrigerant leak.
Another common problem is “freezing” of products at the back wall when the regulator is set to medium values. This can happen if the duct damper (on NoFrost systems) is stuck open, or if you load too much warm food at once. In such cases, a short-term decrease in cooling intensity (turning the knob towards “1”) may not help; defrosting or calling a specialist will be required.
It is also worth considering seasonality. In winter, when the room temperature drops below +16°C, some single-compressor refrigerators may stop turning on if the regulator is set to minimum. In this case, you have to artificially create a load by setting a lower temperature (closer to Max) in order to “start” the compressor operating cycle.
⚠️ Attention: If you do not feel resistance when turning the knob or you hear a crackling sound inside the mechanism, the thermostat may be broken. Do not use excessive force to avoid breaking off the stem.
The influence of external factors on the operation of the thermostat
The efficiency of the refrigerator Beko depends not only on the position of the handle, but also on environmental conditions. Room temperature is a key factor. If the kitchen is +30°C, the refrigerator will have to work at its maximum capacity even with the regulator in the middle position. If the room is +10°C, it may not turn on at all at minimum settings.
Another important aspect is chamber loading. An empty refrigerator “freezes” faster and more strongly than a full one. Products act as cold accumulators. If you just bought a refrigerator or have completely defrosted it, do not immediately set the regulator to Max. Let the system enter the mode gradually, starting from average values.
The location of the refrigerator also plays a role. If it is standing next to a radiator, stove, or in direct sun, the thermostat will “think” that the chamber is warm and force the compressor to work continuously. In this case, even the “0” position (if it meant minimal cold) would not save you from overload, but since “0” is a shutdown, you simply risk losing food.
Frequently asked questions (FAQ)
What should I do if I accidentally left the regulator at “0” overnight?
Nothing bad happened. Simply turn the handle to the working position (for example, “3”). The temperature inside will begin to decrease after 15-30 minutes. It will take several hours for the temperature to fully recover. Check perishable foods (milk, meat) before consumption.
Is it possible to keep the refrigerator constantly on Max?
Not recommended. Max mode is designed for quick cooling or working in very hot areas. Constant operation at maximum leads to increased energy consumption, freezing of food at the rear wall and a reduction in compressor life. Use average values.
Why does the Beko refrigerator not turn on after turning the knob from 0 to 1?
The thermal protection relay may have tripped. Wait 10-15 minutes. If it doesn't start, check to see if there is light inside and power to the outlet. Also make sure that you turn the knob hard enough - sometimes a clear click is required to close the contacts.
Does the number 5 mean a temperature of +5 degrees?
No. The numbers on the mechanical regulator are units of cooling power, not degrees Celsius. The number 5 means the maximum power at which the temperature can drop to 0°C or +2°C, depending on the load and conditions.
