Temperature adjustment in the Biryusa refrigerator two-chamber: instructions with photos and tips

Two-chamber refrigerators Biryusa are one of the most popular in the budget segment due to their reliability and ease of operation. However, even with such models, owners often encounter problems: food freezes on the upper shelves, and milk spoils below, or the freezer is covered with ice, although the refrigerator compartment is barely cooling. In 90% of cases, the reason lies in incorrectly set temperature or unaccounted for features of a particular model.

In this article we will look at how to accurately adjust the temperature in the refrigerator compartment Biryusy (including models 10, 18, 22, 26 and others), what values are considered optimal for different types of products, and why factory settings are not always suitable for real operating conditions. You will also learn how to check the functionality of the thermostat without calling a technician and what to do if the temperature regulator is broken.

Why it is important to correctly set the temperature in the refrigerator compartment

The refrigerator compartment is not just a “cold place”, but a cold zone temperature gradient. Even in one compartment, the difference between the top and bottom shelves can reach 3–5°C. If you set the regulator to maximum, thinking that “this is more reliable,” you risk:

  • 🥩 Spoiling meat and fish - at temperatures lower +2°C they lose their juiciness and become covered with an ice crust.
  • 🥛 Curdle the milk —the optimal temperature for dairy products +3…+4°Cand not +1°Cas many people think.
  • 🍎 Accelerate the rotting of fruit - when +6°C and above apples and pears emit ethylene, which spoils the neighboring ones products.
  • ❄️ Increase the load on the compressor —the lower the set temperature, the more often the motor turns on, which leads to an increase in energy consumption by 15–20%.

On the other hand On the other hand, too high a temperature (+7°C and above) is dangerous for the growth of bacteria. For example, in raw meat, when +8°C salmonella doubles its population every 20 minutes. Therefore, setting the temperature is not only a matter of convenience, but also food safety.

Optimal temperature conditions for the refrigerator compartment Biryusa

Manufacturer in the instructions to models Biryusa 10D, 18K, 22C, 26M and others indicates recommended range for the refrigerator compartment: +2…+6°C. However, this is an average value. In practice, the optimal temperature depends on:

  • 📦 Loading chambers - if the shelves are empty, the cold is distributed unevenly.
  • 🌡️ Room temperatures - in the summer when +30°C in the kitchen the refrigerator requires more intensive cooling.
  • 🍗 Like stored products - for example, cheese needs one temperature, greens need another.
Type of products Recommended temperature, °C Storage shelf
Meat, fish, poultry (raw) +1…+2 Lower (above vegetable box)
Dairy products (milk, sour cream, yogurt) +3…+4 Medium
Ready meals, semi-finished products +2…+3 Upper or middle
Fruits, vegetables (except tropical) +4…+6 Vegetable drawer
Eggs, cheeses, sausages +3…+5 Door or top shelf

In Biryusa models with the No Frost system (for example, Biryusa 22NF), the temperature is distributed more evenly, but still requires adjustment depending on the season. In winter at outside temperature +18°C just set the regulator on 2–3, and in the summer - on 3–4.

Where is the temperature regulator located and how to set it

In two-chamber refrigerators Biryusa the temperature of the refrigerator compartment is controlled using:

  1. Mechanical regulator (rotary disk with numbers from 1 to 7) - in models 10D, 18K, 26M.
  2. Electronic panel with buttons «+»/«–» and display - in series NF (No Frost) i S (for example, Biryusa 22C).

The location of the regulator depends on the model:

  • 🔄 Inside the chamber on the right wall (classic models).
  • 📱 On the top panel outside (electronic control).
  • 🔌 On the back wall near the compressor (rarely, in old modifications).

Disconnect the refrigerator from the network for 10 minutes (to reset)

Set the regulator to position 3 (average value)

Load the chamber with products to 70% (for accurate calibration)

Via 6-8 hours, check the temperature with a thermometer

If necessary, adjust by ±1 division-->

If your model has two. regulator (separately for the refrigerator and freezer compartments), pay attention to the marking. Usually the refrigerator compartment is indicated:

  • 🔵 Blue color or snowflake ❄️.
  • 📛 Inscription «Frige» (from English fridge - refrigerator).
⚠️ Attention: B refrigerators Biryusa s with one regulator (for example, Biryusa 10D) changing the position of the handle simultaneously affects both chambers. To balance the modes, the freezer must be loaded at least 50%.

How to check the temperature without a thermometer

Not everyone has a special thermometer for the refrigerator at hand. But there is 3 proven methods evaluate the temperature regime:

  1. Test with a glass of water

    Place a glass of water on the middle shelf on 8–12 hoursIf after time:

    • 🧊 The water was covered with a thin crust of ice → temperature 0…+1°C (too cold).
    • 💧 The water remained liquid, but very cold → +2…+4°C (optimal).
    • 🌡️ Water is barely cool → +6°C and above (needs to be cooled more strongly).
  2. Oil test

    Apply a thin layer of vegetable oil on a saucer and place on the top shelf. If after 2 hours oil:

    • 🧈 Thickened or turned white → +1…+2°C.
    • 🟡 Retained consistency → +3…+5°C.
    • 🛢️ Became liquid → +6°C and above.
  • Rating by product

    Put on different shelves:

    • 🥛 Milk (should remain fresh 3-4 days at +4°C).
    • 🍌 Banana (in the refrigerator at +6°C turns black within a day, at +4°C - within 2-3 days).
    • 🧀 Cheese (at +2°C becomes crumbly, and when +5°C is smeared).

    Frequent errors when setting the temperature

    Even experienced users sometimes make mistakes that lead to excessive energy consumption or damage to food. Here are TOP-5 misconceptions:

    • ❌ “The colder the better” — setting the regulator to maximum (6–7) increases the load on the compressor and leads to icing of the rear wall.
    • ❌ "You need to open the door often to ventilate" —every time you open the temperature rises by 2–3°C, and the compressor turns on more often.
    • ❌ "Thermostat breaks down only from time" - more often it fails due to voltage surges or mechanical damage (for example, when defrosting, the ice was knocked off with a knife and the tube was touched).
    • ❌ “In the freezer it should be –18°C, and in the refrigerator +5°C" —these are average values. For storing ice cream it is enough –12°C, but for fresh fish you need +1…+2°C.
    • ❌ "If the refrigerator makes noise, it means it is broken" —when first turned on or after defrosting, the compressor runs louder 1-2 hours, this is normal.
    ⚠️ Attention: If after adjusting the regulator, the temperature in the chamber does not change more than 12 hours, this may indicate:
    • 🔌 Malfunction thermostat (replacement required).
    • ❄️ Freon leak (needs repair).
    • ⚡ Problems with the compressor (check if it heats up during operation).

    How to adjust the temperature in refrigerator Biryusa with electronic control

    Models with a display (for example, Biryusa 22NF, 26C) allow you to set the temperature with an accuracy of 1°C. Setting algorithm:

    1. Press the button «Mode» or «Set» (depending on the model).
    2. Use the buttons «+»/«–» select section «Frige» (refrigerator compartment).
    3. Set the desired value (we recommend starting with +4°C).
    4. Confirm the selection with the button «OK» or automatic saving (after 5 seconds).

    Some models have additional functions:

    • 🌙 «Eco» — energy-saving mode (the temperature rises by 1–2°C at night).
    • ❄️ «Super Cool» —intensive cooling (useful after loading a large amount of warm food).
    • 🔄 «Holiday» —mode for long absence (supports +12…+15°C).
    What to do if the display shows an error «E1» or «E2»?

    Error E1 indicates a problem with the refrigerator compartment temperature sensor. Try:

    1. Turn off the refrigerator on 15 minutes.
    2. Check that the door is tightly closed (the seal may be worn out).
    3. If the error repeats, the sensor needs to be replaced (contact service).

    The error E2 is related to the freezer and does not affect the operation of the refrigeration compartment, but also requires diagnostics.

    Seasonal adjustment: winter vs summer

    The room temperature directly affects the operation of the refrigerator. The instructions Biryusa indicate the climate class (for example, N or SN), which determines the range of external temperatures for normal operation:

    Climate class Temperature range, °C Recommendations by setting
    N +16…+32 Summer: regulator on 3–4, winter: on 2.
    SN +10…+32 Summer: 3, winter: 1–2 (at +15°C v room).
    ST +18…+38 In summer: 4, in winter: not lower 2.

    If the refrigerator is on unglazed balcony or unheated room, in winter at a temperature lower +10°C:

    • 🔌 The compressor may not turn on (the oil in it thickens).
    • ❄️ In the freezer the chamber is formed a snow coat due to condensation.
    • 🌡️ The temperature in the refrigerator compartment rises to +8…+10°C.

    What to do if the temperature regulator is broken

    If the rotary dial or electronic panel does not respond to changes, the reasons may be the following:

    1. Mechanical failure of the regulator

      Signs:

      • 🔄 The handle rotates too much easily or, on the contrary, jams.
      • 🔊 When turning, a crunching or grinding sound is heard.

      Solution: Replace the thermostat. For models Biryusa regulators K-59, TAM-133 or TAM-145 (specify by model).

    2. Oxidation contacts

      Signs:

      • ⚡ The refrigerator turns off periodically.
      • 💡 The light inside is on, but the compressor does not start.

    Solution: Clean the contacts with sandpaper or wipe with alcohol If. no experience - call a specialist.

  • Temperature sensor malfunction

    Symptoms (for electronic models):

    • 📱 The display shows incorrect values (for example, –5°C in the refrigerator compartment).
    • 🔄 The cooling mode does not change after setting.

      • Solution: Replacing the sensor. In models Biryusa NF it is located behind the plastic panel on the back wall.

    ⚠️ Attention: If you decide to replace the thermostat independently do not use parts from others. brands (for example, Atlant or IndesitEven externally identical regulators may have different response characteristics, which will lead to the refrigerator not operating correctly.

    The cost of replacing the thermostat at the service center: 1 500–3 000 ₽ (depending on the model and region). If the refrigerator is under warranty, repairs will be free.

    FAQ: Frequently asked questions about setting up. temperatures in Biryusa

    Is it possible to set different temperatures on the top and bottom shelves?

    No, in standard models Biryusa the temperature is controlled centrally. However, you can:

    • 🧊 Use the freshness zone (if available) for products that require 0…+1°C.
    • 🥬 Rearrange products: the lower shelves are always colder than the upper ones by 1–2°C.
    Why in the refrigerator Biryusa 18K on Ice freezes on the back wall, although the temperature is normal?

    This is typical for models with drip defrosting systemReason:

    • 🚪 Frequent or long opening of the door (moist air gets inside).
    • 💧 The drainage hole is clogged (water does not drain, but freezes).
    • 🌡️ The regulator is at maximum cooling (6–7).

    Solution: Defrost the refrigerator for 12 hours, clean the drainage and set the regulator to 3–4.

    What should be the temperature in the refrigerator Biryusa for storing medicines (insulin, vaccines)?

    A range is required for medications +2…+8°C. In the refrigerator Biryusa:

    • 💉 Place medications on middle shelf (where the temperature is most stable).
    • 📊 Use a separate thermometer for control (the error of the built-in sensor can reach ±2°C).
    • ❄️ Do not place medications in the door or near the walls (drops are possible there).
    I heard that new models Biryusa have a “Vacation” function. How does it work?

    Mode «Holiday» (or "Vacation") maintains the temperature in the refrigerator compartment at +12…+15°C, which prevents the appearance of mold and odors during a long absence. In the freezer compartment, the temperature remains standard. (–18°C). Activated:

    1. On electronic models: hold the button «Holiday» 3 seconds.
    2. On mechanical ones: set the regulator to position «H» or «Vacation» (if any).

    ⚠️ Before turning on the mode, remove all perishable foods!

    After moving, the refrigerator Biryusa 22C began to cool worse?

    Probable reasons:

    • 🚛 Transportation without following the rules — the compressor could be damaged if the refrigerator was transported lying down or at an angle.
    • ⚡ Power surge —after connecting to a new network it could burn out starting capacitor.
    • 🌡️ Conditions have changed —if the kitchen is hotter/colder than before, a readjustment is required.

    Solution:

    1. Give it to the refrigerator stand 4–6 hours after moving (to stabilize the oil in the compressor).
    2. Check the voltage in the outlet (should be 220–230 V).
    3. If the problem has not disappeared - call a technician to diagnose the compressor.
