How to set the temperature in the Biryusa refrigerator

Correctly adjusting the climate inside the refrigerator compartment is not just a matter of comfort, but a key factor in the safety of your products and saving energy. Owners of domestic brand equipment Biryusa often face the need to adjust the operation of the unit depending on the season or load volume. Incorrectly set parameters can lead to spoilage of milk, freezing of vegetables, or, conversely, to insufficient cooling, which will cause the growth of bacteria.

Modern models, such as Biryusa 133 or newer series with electronic control, require a careful approach to calibration. Even if you have a classic single-compressor version with a mechanical regulator, understanding the principles of the thermostat will allow you to avoid common mistakes. In this article, we will look in detail at how to set up the optimal microclimate, taking into account the design features of your model.

Before you begin to actively adjust the knobs or buttons, you must allow the unit to enter operating mode. If you have just installed the refrigerator or defrosted it temperature stabilization it may take from 4 to 12 hours. During this period, you should not interfere with the operation of the automation, since the thermometer readings will be incorrect.

The principle of operation of the thermostat in Biryusa models

Most refrigerators Biryusa use a mechanical or electronic thermostat that controls the on and off cycles turning off the compressor. Mechanical models are equipped with a rotary knob, usually located inside the refrigerator compartment or on the top panel of the cabinet. The numbers on the scale do not indicate degrees Celsius, but indicate cooling intensity.

The higher the number on the regulator, the colder it will be inside the chamber. However, this is not a linear relationship, but rather an indication of the power of the compressor. When the knob is set to the maximum value (often referred to as MAX or 7), the compressor can run almost continuously, which leads to increased energy consumption and wear on the motor.

⚠️ Attention: Do not set the knob to the maximum value immediately after turning on. A sharp jump in the load on the compressor can lead to its premature failure or activation of the protective relay.

Electronic control systems found in luxury models or new series allow you to set the exact temperature in degrees. Here the principle is different: you select the target value, and microprocessor itself regulates the duration of the compressor operation to achieve it. This provides a more stable climate and smaller temperature changes when opening the door.

Step-by-step instructions: setting up a mechanical regulator

If your refrigerator is equipped with a classic rotary knob with numbers from 1 to 7 (or from Min to Max), the setting process is as follows. First determine the current position of the control. For standard operating conditions, the position 3 or 4is considered optimal. This value provides a balance between high-quality cooling and energy consumption.

To change the mode, turn the knob in the desired direction. This should be done smoothly, without sudden jerks, so as not to damage the switching mechanism. After changing the position, wait a few hours for the temperature inside the chambers to stabilize. Only after this can you evaluate the result and make adjustments.

It is important to understand that the position of the regulator directly affects the operation evaporator. When set to "1", the compressor will turn on rarely and will not operate for long, which may not be hot enough in the summer. When set to "7", it will work constantly, trying to reach an unattainable minimum, which will lead to the formation of a "fur coat" and freezing of the rear wall.

Setting electronic control panels

In models with electronic control, such as some modifications Biryusa 6 or Biryusa 135, settings are made through the display on the outer door or inside the chamber. Here you are dealing with specific degrees. For the refrigerator compartment, the normal range is from +2°C to +5°C, and for the freezer - from -18°C to -24°C.

To change the settings, you usually need to press and hold the setting button (often indicated as Set or thermometer icon) for 3-5 seconds. After activating the editing mode, use the "+" and "-" buttons to select the desired value. Confirmation of the choice often occurs automatically after you stop pressing or by pressing the set button again.

Electronics allows for more flexible control super freezing mode. Activating this function forces the compressor to run for a long time, quickly freezing fresh food without the formation of large ice crystals that destroy the tissue structure of meat or fruit. However, you cannot keep this mode on all the time.

Seasonal adjustment and environmental influences

The temperature in the room where the refrigerator is installed plays a critical role in its operation. In winter, when the apartment is cooler, there is less heat gain and the compressor takes less time to maintain the cold. In summer, especially in the heat, the load on unit increases significantly. Ignoring this fact is a common cause of breakdowns.

In the summer, if the temperature in the kitchen exceeds +25°C, it makes sense to slightly increase the cooling power (move the knob 1 notch towards larger numbers). However, you should remember the limit: if the room is too hot, even the maximum setting may not help, and the compressor will work hard. In such cases, it is better to ventilate the room or provide air flow to the condenser (grid at the back).

In winter, on the contrary, if the room becomes colder than +16°C, mechanical models may behave incorrectly: the compressor will turn on rarely, and it will begin to melt in the freezer. To work in unheated rooms or on a balcony (if permitted by the instructions), a special climate class or installation of a winter kit is required, although for household models Biryusa this is often not provided by the factory.

⚠️ Attention: Do not install the refrigerator close to the wall or furniture. For effective heat removal, the gap between the rear wall of the case and the wall must be at least 5-7 cm. Violation of this rule in the summer will lead to overheating.

Common errors when adjusting

One ​​of the most common mistakes is trying to “increase the cold” by setting the regulator to maximum immediately after loading a large amount of warm food. This will not speed up cooling, but is guaranteed to overload the system. The products cool down gradually, and the compressor will simply idle at its limit.

Another mistake is ignoring the condition of the door seals. If the elastic does not fit tightly, warm air enters. The user sees that the temperature is rising and turns the regulator to maximum. The result is ice freezing, compressor breakdown and still spoiled food. First check tightness the circuit.

Also, users often forget about the placement of products. If the chamber is tightly packed so that cold air does not circulate, the temperature sensor may show incorrect values, being in a “heat pocket”. The air flow from the evaporator must pass freely between the products.

Diagnostics of problems: when the settings do not help

There are situations when you set the correct mode, but there is no desired result. If, when the regulator is set to medium values, the food in the refrigerator compartment freezes, but in the freezer, on the contrary, everything melts, this may indicate a refrigerant leak or a malfunction of the thermostat. In this case, simple calibration will no longer help.

If the compressor runs continuously, hums, but does not gain cold, check if the drain hole is clogged. Sometimes water that does not go down the drain freezes in the channel, blocking air circulation. Cleaning the hole with a special flexible wire or brush often solves the problem.

If the refrigerator turns on and off with a characteristic click at short intervals (picket fence), the problem may be in the start relay or the compressor itself. Here, adjusting the temperature is pointless and requires the intervention of a specialist. Repairing complex components on your own without skills is dangerous.

⚠️ Attention: If you smell burnt wiring or see sparking in the area of ​​the thermostat, immediately unplug the refrigerator. Further operation is prohibited until the malfunction is eliminated.
