Sometimes users are faced with a situation when food in the refrigerator begins to freeze, and vegetables lose moisture and spoil faster than expected. This is a sure sign that temperature conditions is set too low for the current operating conditions or the volume of loaded chambers. In such cases, it is necessary to intervene in the operation of the cooling system in order to adjust the climate inside the unit.
Refrigerators of the brand Biryusa, produced by the Krasnoyarsk plant, are famous for their reliability and ability to operate in a wide range of climatic conditions. However, even the highest quality equipment requires proper configuration. If you notice an ice crust on the back wall or the food in the main chamber has frozen, then it’s time increase the temperature to comfortable values.
The adjustment process directly depends on the type of control of your model. The brand's line includes both classic mechanical thermostats and modern electronic systems with a digital display. Understanding the operating principle of your particular device is the first step to solving the problem without calling a specialist.
Features of temperature conditions in different models
Before you start setting up, it is important to understand the design of your refrigerator. Models Biryusa can be equipped with one or two chambers, as well as various heat removal systems. In classic models with drip system the evaporator is located on the back wall, and the cold is distributed by natural convection.
In more modern versions, such as series Biryusa 6 or Biryusa 133, the No Frostsystem is often used. Here, air circulates forcibly through special channels, which eliminates the formation of ice, but requires more precise adjustment of the sensors. An error in adjustment can lead not only to spoilage of food, but also to increased energy consumption.
⚠️ Attention: Do not try to suddenly change the thermostat settings. A sudden change in temperature can cause stress to the compressor and lead to premature wear.
The normal temperature for the main compartment is considered to be in the range from +2 to +5 degrees Celsius. If the values are lower, the products freeze, if higher, bacteria begin to multiply. The critical threshold is considered to be a temperature below 0 degrees in the main chamber, which is unacceptable for most fresh products. Correct setting ensures a balance between food safety and energy efficiency.
Setting the mechanical thermostat
In most models of refrigerators Biryusa with mechanical control, adjustment is carried out using a rotary knob located inside the chamber or on the front panel. The scale usually contains numbers from 1 to 7 (or from Min to Max). It is important to understand that these numbers do not mean degreesbut indicate the intensity of the compressor.
To increase the temperature (make it warmer in the refrigerator), you need to turn the knob towards a lower value. If the regulator was at "5" or "6", move it to "3" or "2". This will reduce the operating time of the compressor and allow the temperature inside to rise to the desired level.
- 🌀 Turn the regulator knob counterclockwise to reduce the cold.
- 🌡️ The optimal average value for mechanics is position "3".
- ⏳ After changing the setting, wait 12-24 hours for mode stabilization.
- 🔊 Pay attention to the sound of operation: the compressor should turn on less often.
Some users mistakenly believe that setting the knob to maximum (7 or Max) will cool the food faster. This is a misconception. In this mode, the compressor works non-stop, trying to reach an unattainable minimum, which leads to freezing and breakdown. To increase the temperature do the opposite - lower the value.
Electronic control adjustment
Models with electronic control, often designated in the name by the index "E" or "K", allow you to set the exact temperature in degrees. The control panel may be located on the outside door or inside the top of the refrigerator compartment. Here the setup process is more accurate and understandable.
To change parameters, use the "+" and "-" buttons or touch icons on the display. If you want to make the chamber warmer, press the increase value button (plus) until the desired number is displayed on the screen, for example +4 or +5 °C. The system will automatically support this mode.
| Value on display | Operating mode | Recommendation |
|---|---|---|
| +1... +2 °C | Intense cold | Only for quick freezing or storing meat |
| +3... +5 °C | Standard mode | Optimal for everyday storage |
| +6... +8 °C | Economy / Warm | For storing vegetables or for small loads |
| OF / OFF | Shutdown | The refrigerator compartment does not works |
In some modifications Biryusa with two compressors, you can independently regulate the temperature in the freezer and refrigerator compartments. Make sure you are tuning the exact circuit that needs it. Often users confuse the display of temperatures by looking at the freezer settings, when the problem is in the main compartment.
☑️ Checking the electronics settings
Factors affecting the temperature inside
Even a properly configured thermostat may not give the desired result if you ignore external factors. The temperature inside the refrigerator Biryusa depends not only on the position of the handle, but also on the operating conditions. The loading density of the chambers plays a key role: an empty refrigerator cools down faster, but holds the cold worse when the door is opened.
The location of the unit also matters. If the refrigerator is located close to the wall or next to heating devices, heat exchange is disrupted. The compressor is forced to work harder to compensate for external heat, which can lead to overcooling of the food if the thermostat does not have time to react.
- 🚪 Frequently opening the doors releases warm air, throwing off the settings.
- ☀️ Direct sunlight heats the case, causing the system to freeze more.
- 🧊 A thick layer of ice on the evaporator (in models without No Frost) impairs heat transfer.
- 🍲 Hot dishes placed inside sharply increase the overall temperature.
⚠️ Attention: Never put hot pots in the refrigerator. This will not only increase the temperature, but will also force the compressor to work hard, trying to cool a large volume of heat.
Seasonality should also be taken into account. In summer, when the ambient temperature in the room is high, the refrigerator can work more intensely. In winter, if the kitchen is not heated, the standard settings may turn out to be excessive, and the temperature will have to increase manuallyturn the regulator to minimum.
Why is it cold in the freezer, but warm in the refrigerator?
This is a common problem with single-compressor models. If the cold air supply channel is clogged or the damper (fluster) is faulty, the cold does not enter the upper chamber. Check whether the air ducts are blocked by products.
Typical errors during adjustment
The most common mistake is impatience. Users turn the thermostat knob, wait half an hour, see no result, and turn it further. Thermal stabilization in the refrigeration chamber is an inertial process. The refrigerant and the chamber walls need time to warm up or cool down to new values.
Another mistake is ignoring the condition of the seals. If the rubber band on the door Turks does not fit tightly, heat constantly flows inside. The thermostat “sees” the temperature increase and causes the compressor to freeze even more. As a result, there may be ice in the chamber, but due to the constant influx of warm air, the products at the door will deteriorate.
Improper placement of products also interferes with air circulation. If you pack the shelves all the way to the top, blocking the duct outlets, the temperature sensor may be reading incorrect data. This leads to the system not working correctly and the temperature regime being disrupted.
Sometimes users try to “deceive” the system by sealing the sensor or changing its position. Do this It is strictly forbidden. The sensor must read the actual air temperature in the chamber. Any manipulations with its location will lead to chaotic operation of the equipment.
When specialist help is needed
There are situations when adjusting the thermostat does not help. If you have set the minimum values, more than a day has passed, and the food is still freezing, or vice versa - the chamber is too warm even at maximum, the problem may be technical. There may be a refrigerant leak or failure of the thermostat itself.
You can suspect a malfunction based on characteristic signs: the compressor works without stopping or, conversely, does not turn on at all; a gurgling sound is heard inside; A “coat” of ice of uneven thickness has formed on the back wall. In such cases, independent intervention can only aggravate the situation.
Service center specialists have equipment to measure the pressure in the system and check the tightness of the circuit. Repairs may involve replacing the thermostat, refilling with freon, or restoring the control circuit. Remember that Biryusa is a reliable brand, and most often the problem is solved by simple reconfiguration, but you should not forget about technical risks.
What to do if it is too cold in the Biryusa refrigerator compartment?
First of all, check the position thermostat. If it is set to maximum, move it to the middle value (usually "3"). Make sure food does not block air flow. If after a day the situation has not changed, the thermostat contact may have stuck and needs to be replaced.
What is the normal temperature in the Biryusa freezer?
The optimal temperature for the freezer is -18°C. In the Super Freeze mode, it can drop to -24°C, but constantly maintaining this mode is not recommended due to the high energy consumption.
Why does the refrigerator take a long time to gain temperature after defrosting?
After complete defrosting, the walls and food require time to cool. Depending on the volume of the chamber and the number of products, this process can take from 4 to 12 hours. Do not load warm products right away, let the system return to mode.
Is it possible to use an external thermometer to check?
Yes, this is the best way to control. Place a regular household thermometer in a glass of water on the middle shelf. Leave for several hours. The readings must correspond to the settings of your thermostat.
