Temperature regulator in the Biryusa refrigerator: where to turn and how to set it correctly

The refrigerator Biryusa is a time-tested assistant in the kitchen, but even with it sometimes questions arise. One of the most common: "Where to turn the temperature regulator so that the food does not spoil and the equipment does not wear out?" The answer seems simple, but in practice, many users encounter icing, insufficient cooling, or, conversely, freezing of food. The thing is that the thermostat in the models Biryusa (be it Biryusa-18S, Biryusa-22K or other popular series) has its own characteristics.

In this article we will figure out how set the temperature correctlywhat the divisions on the handle mean, and why sometimes the regulator behaves “illogically”. You will also learn what mechanical thermostats have and how to avoid errors during operation. If your refrigerator freezes too much or, conversely, does not cool well, here you will find a solution. hidden functions mechanical thermostats and how to avoid errors during operation.

How the temperature regulator in the Biryusa refrigerator works

Thermoregulator in refrigerators Biryusa is mechanical devicethat controls the operation of the compressor. In most models (for example, Biryusa-130, Biryusa-226it is a rotating knob with a digital scale from 1 to 7 (less often to 5 or 9). The higher the number, the lower temperature in the chamber.

Inside the regulator there is bellows a sealed tube with gas that reacts to temperature changes. When cooling, the gas is compressed, the contacts open, and the compressor is turned off. When the temperature rises, the gas expands, the contacts close and the compressor starts working again. This principle underlies all mechanical thermostats, including those installed in Biryusu.

It is important to understand that the scale on the handle is conditional. The numbers do not show the exact temperature in degrees, but only indicate level of cooling intensity. For example, the position 3 in one model may correspond to +4°C, and in another - +2°C. It depends on:

• 🔹 Refrigerator models (single-chamber or two-chamber, with No Frost or drip system);
• 🔹 Chamber volume (in large refrigerators, heat exchange is slower);
• 🔹 Room temperatures (if the kitchen is hot, the compressor will have to work longer);
• 🔹 Product load (densely packed products last longer cool down).

In Biryusa refrigerators with mechanical controls (for example, series K i C), the regulator is often combined with the defrost button. If the knob does not turn smoothly or makes a creaking sound, this may indicate wear on the mechanism - the thermostat will need to be replaced.

Where to turn the regulator: clockwise or counterclockwise?

This is the most common question among owners Turk. The answer is simple:

• 🔄 Clockwise — increasing cold (numbers are rising, temperature is falling).
• 🔄 Counterclockwise — decrease cold (numbers are decreasing, temperature is rising).

However, there is a nuance: in some older models (for example, Biryusa-3 or Biryusa-6M) the scale may be reverse. To avoid mistakes, pay attention to:

1. Marking next to the handle - sometimes there are hints like "Min" i "Max".
2. Compressor behavior —if after turning clockwise the motor starts working longer, it means the cold is increasing.
3. Temperature in the chamber —check it with a thermometer 6-8 hours after changing the settings.

If you are not sure, try the following algorithm:

1. Set the regulator to the middle position (usually 3–4).
2. Place the thermometer in the refrigerator compartment (not the freezer!).
3. After 12 hours, check the readings. The optimal temperature for storing food is +2…+5°C.
4. If it is too warm, turn the knob one notch clockwiseIf it is too cold, one notch counterclockwise. data-i="130">📊 How do you usually adjust the temperature in the refrigerator?.

Optimal settings for different Biryusa models

Refrigerators Biryusa are divided into several series, and each has its own recommendations for setting the thermostat. Below is a table with optimal values for popular models (at room temperature). data-i="138">Biryusa 20–25°C):

For two-chamber models (for example, Biryusa-22K) are often provided two regulators: one for the refrigerator compartment, the other for the freezer. In this case:

• 🥶 Freezer: optimal position - 4–5 (temperature -18…-20°C).
• 🥦 Refrigerator compartment: 2–3 (temperature +3…+5°C).

⚠️ Attention: In models with No Frost (for example Biryusa-226) the freezer regulator is often combined with button "Super Freeze". If it is activated, the compressor will work without stopping until the temperature drops to -24°C. Do not forget to turn off this mode after freezing a large volume of food!

What to do if the regulator does not work or behaves strangely

Sometimes the thermostat knob turns, but the temperature in the refrigerator does not change, or the compressor works without stopping. This may indicate:

• 🔧 Thermostat breakdown —the most common case. The bellows loses its tightness, and the gas stops responding to temperature.
• ❄️ Icing of the evaporator —if the refrigerator has not been defrosted for a long time, ice blocks air circulation.
• ⚡ Problems with the compressor —it may not turn on due to a faulty start relay.
• 🔌 Electrical circuit malfunction —oxidation of contacts or broken wires.

Check the following:

If the compressor does not respond to changes in the position of the handle, it is most likely to blame thermostat. You can replace it yourself (in models Biryusa this is not difficult), but for this you will need:

1. Disconnect the refrigerator from the network.
2. Remove the protective cover (usually it is attached to latches or screws).
3. Disconnect the wires from the thermostat (remember their location!).
4. Remove the old thermostat and install a new one (for example, K-59 or TAM-133, depending on the model).

⚠️ Attention: In refrigerators Biryusa with electronic control (for example, Biryusa-226HF) instead of a mechanical thermostat, temperature sensoris used. If the regulator does not respond, the problem may be with the control board. In this case, it is better to contact the service center.

Typical errors during setup temperature

Many users operate the regulator incorrectly, which leads to food spoilage or equipment breakdown. Let's look at the most common mistakes:

1. Setting the maximum cold (6–7) "just in case"

This leads to:

• 🧊 Icing of the back wall (in models with a drip system).
• ❄️ Refreezing food (for example, cucumbers become soft, milk sours faster).
• ⚡ Increased energy consumption (the compressor runs almost non-stop).

2. Regularly changing the position of the regulator

The thermostat needs time to stabilize the temperature. If you constantly turn the knob, the compressor will turn on and off too often, which will shorten its life.

3. Ignoring the room temperature

In the summer, when in the kitchen +30°C, the refrigerator requires more power for cooling. If the settings are not adjusted, food may spoil. Recommendations:

• 🌡️ At room temperature 16–25°C — regulator on 3–4.
• 🔥 At temperature 25–30°C — regulator on 4–5.
• ❄️ At temperature below +16°C — regulator on 2.

4. Setting by freezer, not by refrigerator

Many people focus on the freezer, forgetting that the main task of the regulator is to maintain the temperature in refrigerator compartment. The freezer usually has a separate thermostat or works in tandem with the main one, but its settings should not dictate the overall temperature.

How to check the operation of the regulator without a thermometer

If you don’t have a thermometer at hand, you can evaluate the correctness of the settings by indirect signs:

Signs of too low temperature (0…+2°C):

• 🥛 Milk and kefir freeze at the edges of the package.
• 🍅 Vegetables (cucumbers, tomatoes) become soft and watery.
• 🧀 The cheese becomes covered with frost.
• ❄️ On the back ice forms on the wall (in models without No Frost).

Signs of too high a temperature (+6°C and above):

• 🥩 Meat quickly deteriorates (an unpleasant odor appears).
• 🥚 Eggs lose their freshness after 2–3 days.
• 🧅 Onions and garlic sprout.
• 💧 Condensation accumulates on the walls of the chamber.

If you observe these signs, adjust the settings:

1. When freezing turn the knob one division counterclockwise.
2. When insufficient cooling - one division clockwise.
3. Wait 6–12 hours (temperature stabilization time).
4. Repeat the check.

⚠️ Attention: In refrigerators Biryusa with a system No Frost (for example, Biryusa-226HF) the back wall should not freeze. If ice still appears, this is a sign of a malfunction. In this case, the regulator is not to blame - diagnostics are needed. defrost heater or timer. In this case, the regulator is not to blame - diagnostics are needed.

Frequently asked questions about the regulator in the Biryusa refrigerator

🔹 Is it possible to set different temperatures in the refrigerator and freezer?

In most models Biryusa (for example, Biryusa-22K) there is two independent regulators: one for the refrigerator compartment, the other for the freezer. In single-chamber refrigerators (for example, Biryusa-130), the temperature of the freezer depends on the general thermostat and is usually fixed at the level -18°C.

🔹 Why does the temperature not change after turning the regulator?

There are several reasons:

1. The thermostat is jammed —the mechanism is worn out, and the gas in the bellows does not respond to temperature.
2. Broken compressor —it does not turn on regardless of the position of the handle.
3. Faulty start relay —the compressor does not start.
4. Freon leak —the refrigerator does not cool even when the engine is running.

To diagnose, turn off the refrigerator for 10 minutes, then turn on and listen: if the compressor does not start, the problem is electrical or mechanical.

🔹 Which position of the regulator is the most economical?

Optimal ratio of energy consumption and cooling quality - 3–4 (for most models Biryusa). this:

• The compressor operates in normal mode (turns on for 10–15 minutes, turns off for 20–30 minutes).
• The temperature in the chamber is kept at +3…+5°C.
• There is no unnecessary load on the network.

If you set 1–2, the compressor will turn on less often, but the temperature can rise to +6…+8°C, which will shorten the shelf life products.

🔹 Do you need to change the regulator settings in winter?

Yes, if the refrigerator is in an unheated room (for example, in a country house). At low room temperatures, the compressor may not turn on. +16°C:

• Set the regulator to 1–2.
• If food is stored in the freezer, check its condition - if the room temperature is too low, the compressor may not turn on.
• In models with No Frost in winter, it may be activated heating of the seal (so that the rubber does not tan).

🔹 Why does the regulator click when turned?

Clicks are normal behavior of a mechanical thermostatThey mean that:

• Contacts inside the thermostat close/open.
• When turned clockwise, a click signals the compressor is turned on.
• When turned counterclockwise - o open circuit (the compressor will turn off when the temperature reaches set value).

If clicks are accompanied crackling, creaking or sticking handle, the thermostat requires replacement.
