Refrigerator owners Biryusa often face the question: what do the mysterious numbers on the display or mechanical regulator mean? These symbols can indicate temperature conditions, signal errors, or activate additional functions. Without a correct understanding of these symbols, you risk encountering freezing of food, increased energy consumption, or even breakdown of equipment.
In this article we will analyze in detail all the possible meanings of the numbers on refrigerators Biryusa —from classic models with mechanical control (Biryusa-18K, Biryusa-22) to modern ones with electronic display (Biryusa-145, Biryusa-151). We will pay special attention to deciphering error codes, optimal temperature settings and hidden functions, which are not mentioned in the instructions.
If your refrigerator suddenly started flash numbers, make beeps or refuse to freeze - here you will find clear instructions on how to act. And for those who are just planning a purchase, we will compare control systems of different generations Biryusa and explain which numbers are really important when choosing a model.
1. Numbers on a mechanical regulator: what does the scale from 1 to 7 mean?
In refrigerators Biryusa with mechanical control (for example, Biryusa-18K, Biryusa-22, Biryusa-130), the temperature is regulated by a rotary knob on which numbers from 1 to 7are printed. Many people mistakenly believe that these are degrees Celsius - but in fact it is Biryusa-18K Biryusa-22 Biryusa-130 1 to 7 conditional divisions of cooling power.
Here's how to correctly interpret these numbers:
- 🔹 1–2 — minimum cooling (suitable for storing vegetables, fruits, drinks at +8...+10°C). In the freezer with this setting, the temperature will be about -6...-8°C.
- 🔹 3–4 —standard mode (optimal for most products). Refrigerator compartment: +4…+6°C, freezer: -12…-16°C.
- 🔹 5–6 — enhanced cooling (recommended for hot climates or when loading a large amount of warm products). The temperature in the freezer drops to -18...-22°C.
- 🔹 7 —maximum power (used for quick freezing or in emergencies, for example, during a power outage). Long-term operation in this mode increases energy consumption and wear of the compressor.
Important: The numbers are not equal to degrees! The actual temperature depends on the load of the refrigerator, the frequency of door opening and external conditions. For example, in the model Biryusa-130 with the regulator position at "4" in the refrigeration chamber it can be +5°C, and in Biryusa-22 — +7°C.
⚠️ Attention: If the control knob is in the “0” or “Off” position, but the refrigerator continues to work, this is a sign of a thermostat malfunction. In this case, replacement of the part is required, since the compressor will work without stopping, which will lead to overheating.
How to check the operation of the thermostat manually?
To diagnose the thermostat, turn the regulator to the maximum value (7) and listen: the compressor should turn on within 5-10 minutes. If this does not happen, the thermostat is faulty. Also check whether the compressor turns off when the knob is turned to "0".
2. Electronic display: decoding of numbers and symbols
Modern models Biryusa (for example, Biryusa-145, Biryusa-151, Biryusa-228) are equipped with an electronic display that displays numbers, letters and pictograms. Here the numbers can already mean exact degrees, error codes or timers.
Let's look at the basic symbols:
| Symbol on the display | Value | User actions |
|---|---|---|
| +4…+8 | Current temperature in the refrigerator compartment (in °C) | Optimal range: +4…+5°C. If above +7°C, check the seal or the load in the chamber. |
| -12…-24 | Temperature in the freezer (in °C) | For long-term storage of meat/fish, set to -18°C. Mode "-24" is used for shock freezing. |
| F1, F2, F3 | Error codes (faulty sensor, compressor or control board) | Requires diagnostics by a service center. Do not try to reset the error by turning off the power - this may worsen the breakdown. |
| SAB or DEF | Super Freeze or Super Cool mode | Activated for 24 hours, then turns off automatically. Use for quick freezing of large volumes of food. |
| AL or DOOR | Door open signal (sound + flashing indication) | Check that the door is tightly closed. If the signal does not disappear, the seal may be worn out or the sensor may be faulty. |
In models with dual-chamber control (for example, Biryusa-228) the display can display two temperatures simultaneously: the top line is the refrigerator compartment, the bottom line is the freezer. If the numbers are blinking, this indicates:
- 🔋 Power failure (you need to restart the refrigerator by unplugging it for 1-2 minutes).
- ❄️ Evaporator icing (defrost required).
- 🚨 Critical temperature deviation (check compressor operation).
3. Numbers in model indices: what do the numbers in the name of the refrigerator mean
Model numbers Biryusa (for example, Biryusa-18K, Biryusa-145, Biryusa-228) also carry useful information. By deciphering them, you can understand chamber volume, control type and even year of manufacture (for some series).
General structure of the index:
- 📌 First digits (18, 145, 228) — total usable volume in liters. For example, Biryusa-145 has a volume of 145 liters.
- 📌 Letters (K, S, M) - type of compressor or control system:
- K - classic compressor (for example, Biryusa-18K).
- WITH - system No Frost (without defrosting).
- M —a modern modification with electronic control.
- 📌 Additional numbers/letters —series or year of manufacture (for example, Biryusa-130.2 —the second modification of model 130).
Examples of decoding:
- 🔢 Biryusa-18K - refrigerator with a volume of 180 liters with a classic compressor.
- 🔢 Biryusa-228C - model on 228 l with system No Frost.
- 🔢 Biryusa-151M — 151 l, electronic control.
⚠️ Attention: In the names of some older models (for example, Biryusa-3 or Biryusa-6) the numbers indicate not the volume, but the series. These refrigerators were produced in the 1990–2000s and have a volume of 120–160 liters. Check the specifications according to your passport.
4. Numbers on the freezer: freezing modes and their purpose
In freezers Biryusa (both individual and as part of combined models), the numbers on the regulator or display indicate freezing intensity. Here the principles differ from the refrigeration chamber:
For mechanical regulators (models Biryusa-101K, Biryusa-110):
- 🥶 1–2 —maintaining a temperature of -6...-12°C (for short-term storage).
- 🥶 3–4 —standard mode (-18°C, suitable for most products).
- 🥶 5–6 —intensive freezing (-20...-24°C, for long-term storage meat/fish).
- 🥶 7 — shock freezing (-24...-30°C, used up to 24 hours).
For electronic panels (models Biryusa-151M, Biryusa-228C):
- ❄️ -12°C —storage mode (for already frozen products).
- ❄️ -18°C —standard mode (optimal for home use).
- ❄️ -24°C —deep freezing (for fresh berries, meat, seafood).
- ❄️ SAB/DEF — super freezing (activated for 24 hours, then returns to the previous mode).
The "shock freezing" mode (-24°C and below) cannot be used constantly - this leads to increased wear on the compressor and an increase in energy consumption by 30–40%. SAB, then change to -18°C.
Make sure food is sealed tightly|
Make room around the ventilation openings|
Set the panel to SAB/DEF|
Do not open the door in within 12–24 hours|
After freezing, return to standard mode (-18°C)

5. Fault indicator numbers: how to decipher errors
If flashing numbers appear on the refrigerator display Biryusa alphanumeric codes (for example, F1, E2, H1), this indicates a malfunction. The decoding depends on the model and year of manufacture, but there are general patterns:
| Error code | Probable cause | Recommendations |
|---|---|---|
| F1 | Malfunction of the refrigerator compartment temperature sensor | Check the sensor wiring. If the error remains, replace the sensor. |
| F2 | Problem with the freezer compartment sensor | Similarly F1. An open circuit is also possible. |
| E1 | Compressor jamming or overheating | Turn off the refrigerator for 1 hour. If the error repeats, repair is needed. |
| H1 | High voltage in the network (more than 240V) | Connect the stabilizer voltage. The error will reset automatically. |
| L1 | Low voltage (less than 180V) | Check the network or use a UPS. |
In models Biryusa with the system No Frost (for example, Biryusa-228S), additional codes may appear:
- 🔧 dE — malfunction of the defrosting system (check the evaporator heating element).
- 🔧 CF —fan malfunction (ice may form on the blades).
⚠️ Attention: If the error appears again after resetting the power supply, do not try to repair the refrigerator yourself. In 70% of cases, this leads to worsening of the breakdown (for example, when replacing the sensor without disconnecting the control board), contact a service center Biryusa or an authorized one. to the technician.
6. Hidden functions: what do the combinations of numbers on the panel mean? are intended for diagnostics, but can also be useful in everyday life.
Few people know, but in refrigerators Biryusa with electronic control yes hidden service modes, which are activated by certain combinations of buttons. These functions are intended for diagnostic purposes, but can also be useful in everyday life.
Examples of hidden commands (for models Biryusa-145M, Biryusa-151M, Biryusa-228S):
- 🔐 Hold "Freezer" + "Refrigerator" 5 sec — entrance to test mode (checking sensors, compressor, display).
- 🔐 Press "Super" 3 times in a row —reset all settings to factory settings.
- 🔐 Hold "Temperature +" and "Temperature -" —turn on/off sound signals.
- 🔐 Press "Light" + "Super" - activation demonstration mode (for stores, turns off cooling).
In models with No Frost (Biryusa-228S) there is an additional function:
- ❄️ Holding "Super Freeze" for 10 seconds - forced start defrosting the evaporator (useful for icing).
⚠️ Attention: Inaccurate use of service modes can lead to firmware failure. For example, if you interrupt the test mode by turning off the power, the refrigerator may stop responding to buttons. Before experimenting with combinations, study. instructions or save the contacts of the service center.
7. Frequently asked questions: why the numbers blink, do not change, or show incorrect values
Users of refrigerators Biryusa often encounter non-standard behavior of indicators. situation:
1. The numbers on the display are blinking, but the refrigerator is working:
- 💡 Possible reason: voltage surge or control board failure.
- 💡 Solution: Turn off the refrigerator for 5-10 minutes. If the blinking continues, check the voltage (should be 220V ±10%).
2. The numbers on the regulator do not change the temperature:
- 💡 Possible reason: (for mechanical models) or thermostat failure (for mechanical models) or sensor malfunction (for electronic). turn the regulator. If not, repair is needed.
- 💡 Solution: Check if the compressor turns on when you turn the knob. If not, it needs repair.
3. The display shows the wrong temperature (for example, +20°C in the freezer):
- 💡 Possible reason: sensor failure or evaporator icing (blocks circulation air).
- 💡 Solution: Defrost the refrigerator for 12-24 hours. If the problem persists, replace the sensor.
4. electricity:
- 💡 Possible reason: settings memory failure (typical for older models).
- 💡 Solution: Set the parameters again. If the failures persist, check the control board.
FAQ: Answers to popular ones. questions
❓ What does the number “5” mean on the regulator of the Biryusa-18K refrigerator?
In the model Biryusa-18K the number "5" corresponds to enhanced cooling mode. In the refrigerator compartment the temperature will be about +2...+4°C, in the freezer - -18…-20°C. This mode is suitable for hot weather or when loading a large number of products.
❓ Why does “H1” light up on the Biryusa-151M display?
The code H1 signals about high voltage in the network (more than 240V). The refrigerator automatically turns off the compressor for protection. Solution: connect a voltage stabilizer or check the home electrical network.
❓ How to reset error F2 on Biryusa-228S?
Error F2 indicates a problem with the freezer sensor. Try to reset it like this:
- Disconnect the refrigerator from the network for 1 minute.
- Plug it back in and hold the "Super Freeze" button for 10 seconds.
- If the error remains, the sensor needs to be replaced.
❓ What to do if the numbers are on the display Biryusa-145 do not light up?
If the display does not turn on, but the refrigerator is working:
- Check the connection of the display cable (the contact may have come loose).
- Make sure that the backlight function is activated (in some models it is turned off with the "Light" button).
- If the display is dead, the control board or the screen itself is faulty.
❓ Is it possible to set the temperature to -24°C on Biryusa-130?
In the model Biryusa-130 (mechanical control) the maximum temperature in the freezer is about -18°C (position regulator "7"). To achieve -24°C, an upgrade (replacement of the thermostat or compressor) will be required, which is not economically feasible. Consider purchasing a model with No Frost, for example, Biryusa-228S.
