Many owners of household appliances are faced with a situation where it is necessary to change the standard operating mode of the unit. For example, during the procurement period or when storing a large volume of fresh products, there is a need to use only the refrigerator compartment. The question of how to turn off the freezer compartment in the Biryusa refrigerator becomes especially relevant for users who want to optimize energy consumption or expand the useful volume for cooling.
Modern models, such as Biryusa 133 or newer series with electronic control, offer different algorithms for the operation of the compressor and cold distribution system. However, classic two-chamber devices often have a single refrigeration system, where complete shutdown of one zone is physically impossible without disrupting the operation of the entire structure. Understanding the operating principle of your specific device is the first step to competent operation.
In this article we will analyze in detail the technical nuances of setting temperature conditions, explain the difference between a complete shutdown and switching to the “Vacation” mode, and also consider the features of the operation of evaporators in different modifications. You will learn which manipulations are permissible and which can lead to equipment breakdown.
Principles of operation of Biryusa two-chamber refrigerators
To figure out whether it is possible to turn off the freezer, you need to understand the basic architecture of the device. Most of the brand's models, especially those in the budget and mid-range segments, are equipped with a system with one compressor and one refrigerant circuit. In such units, cold is generated in the freezer chamber and then circulates into the refrigeration compartment through special channels or dampers.
Freonpassing through the evaporator, it picks up heat, cooling the air. If you try to completely insulate the freezer compartment, the refrigerant cycle will be disrupted. This can lead to overheating of the compressor or the formation of ice plugs in the system. That is why in the instructions for models like Biryusa 6 or Biryusa 134 you will not find a function to completely turn off the freezer.
The situation changes when we are talking about models with a system No Frost or electronic control with two circuits. Here, temperature control is more flexible. However, even in such cases, “shutdown” often means setting the temperature in the chamber to the highest possible temperature, rather than physically stopping the supply of cold. It is technically impossible to force the compressor to work only to cool the upper chamber, ignoring the lower one, if they are connected by a common circuit.
⚠️ Attention: An attempt to mechanically block the cold supply channels or independently interfere with the piping system will lead to irreversible damage to the compressor and loss of warranty.
It is important to distinguish between the concepts of “turn off” and “minimize” work." Under standard operating conditions, the unit strives to maintain a given temperature balance. If you increase the temperature in the freezer to 0°C or -1°C, the compressor will still turn on, but less often, which indirectly affects the refrigerator compartment.
Vacation mode and its effect on the freezer
One of the most popular user requests is to search for a function that allows you to save energy during a long absence. Many Biryusa models, especially those with an electronic display, have a mode often called “Vacation” or “Eco”. This algorithm is designed specifically for situations where the refrigerator compartment must operate and the freezer must switch to economy mode.
When this function is activated, the temperature in the upper compartment is maintained at around +5...+7°C, which is sufficient to store unopened food and prevent mold. At the same time, in the freezer the temperature rises to -9...-12°C. This is not a complete shutdown, but a significant reduction in the load on the system. Energy consumption in this mode it can be reduced by 20-30%.
The mode is usually activated through the control panel. The corresponding indicator may light up on the display. If you have mechanical control (twists inside the chamber), then there is no such mode, and adjustment occurs only by changing the position of the thermostat.
You should remember that when the “Vacation” mode is turned on, the freezer is not intended for long-term storage of perishable foods. Meat, fish or ice cream may begin to thaw or lose their properties faster than at a standard temperature of -18°C.
Adjusting the temperature through the control panel
For models with electronic control (series Biryusa 350, Biryusa 450 and analogues), the process of adjusting temperature zones is carried out through a digital interface. This gives the user the opportunity to adjust the climate inside the chambers as accurately as possible, approaching the desired effect of “turning off” the freezer.
To change the parameters, you usually need to press the mode or temperature selection button. The corresponding camera indicator will flash on the display. Using the Up or Down buttons you can set the value. For a freezer, the range is often -6°C to -24°C. By setting the value to -6°C, you will “turn off” the freezing intensity as much as possible, saving food from rapid spoilage.
☑️ Temperature setting algorithm
It is important to consider that changing settings in one camera may briefly affect the operation of another. The system will strive to equalize the temperature background, so the compressor can work in enhanced mode in the first few hours after reconfiguration.
If the icon Super Freeze (Super Freeze) is lit on the display, it must be turned off manually. This mode forces the compressor to work continuously, ignoring the set temperature limits, which is contraindicated for the economy mode or “soft” storage.
Adjustment of a mechanical thermostat
In classic models such as Biryusa 133 KSh-250 or Biryusa 135, control is carried out using a mechanical thermostat. This is a round handle located inside the refrigerator compartment, often with numbers from 1 to 5 or 7. Many users mistakenly believe that the number indicates degrees Celsius, but this is not so.
The numbers on the regulator indicate the intensity of the compressor. One is the minimum cooling, and the maximum number (for example, 5 or 7) is the maximum freezing. To “turn off” the freezer as much as possible, the knob must be moved to the “1” or “Min” position. In this position, the compressor will turn on less often, and the temperature in the freezer will rise to the maximum possible values for this design.
| Regulator position | Operation intensity | Temperature in the freezer (approximately) | Recommendation |
|---|---|---|---|
| 1 (Min) | Minimum | -6°C ... -8°C | Vacation mode, beverage storage |
| 3 (Average) | Normal | -12°C ... -15°C | Daily use |
| 5 (Max) | Maximum | -18°C ... -24°C | Preparing food for the winter |
| 0 (Off) | Disabled | Room | Full turning off the refrigerator |
There is also a “0” or “Off” position. In this condition, the compressor's power circuit opens and the refrigerator stops working completely. In this case, both chambers are defrosted and heated to room temperature. This is the only way to truly “turn off” the freezer, but the refrigerator compartment will also turn off.
⚠️ Attention: Abruptly turning the regulator from maximum to minimum (or vice versa) creates stress on the refrigerant. It is recommended to change settings gradually, at intervals of several hours.
Using the Super Freeze function
Function Super Freeze often raises questions among users who confuse it with the ability to control the freezer. This mode is designed to quickly freeze large quantities of fresh food. When activated, the compressor runs non-stop, ignoring the thermostat readings, until you manually turn off the function or the automatic cycle goes through (usually up to 72 hours).
If your goal is to lower the temperature in the freezer or, conversely, give it a “rest,” using the Super Freeze mode is contraindicated. It puts extreme stress on the system. To “turn off” or reduce the activity of the freezer, this mode must be deactivated.
How long does Super Freeze work?
In most Biryusa models with electronics, the Super Freeze mode turns off automatically after 24-48 hours. In models with mechanical control (button with indicator), the mode operates until the user presses the button again. Do not leave this mode turned on unless necessary - this will lead to excessive power consumption and the formation of excessive ice.
Sometimes users inadvertently (accidentally) turn on this function by holding down the buttons on the control panel. If you notice that the refrigerator is noisier than usual, or the food in the freezer is frozen solid, check the indicators. A snowflake or inscription Super will indicate the active intensive freezing mode.
Typical errors when trying to turn off
When trying to achieve the desired result, equipment owners often make mistakes that can shorten the service life of the unit. The most common one is to try to cover the ventilation holes between the chambers with cardboard or foam. This is a gross violation of the operating rules.
Blocking air flows leads to the fact that cold does not enter the upper chamber, and a “snow coat” forms in the lower (freezing) chamber due to impaired circulation. The compressor, not receiving the correct temperature signal (since the sensor may be in an area of stagnant air), runs idle or overheats.
Another mistake is frequent changes in settings. If you set the minimum today and the maximum tomorrow, the control system does not have time to stabilize. Thermoregulator and the sensors operate with a certain inertia. It takes 6 to 12 hours for the temperature to stabilize after changing the settings.
Also, do not forget about tightness. If you rarely open the freezer, hoping that there is “nothing” in there and it is turned off, but the door seal is worn out, warm air will constantly enter inside. This will force the compressor to work more often, nullifying all attempts at saving.
The influence of seasonal factors and the environment
The efficiency of the refrigerator and the ability to “turn off” the freezer are highly dependent on the room temperature. In winter, when the apartment is cool (+18...+20°C), the compressor works less often. In such conditions, setting the regulator to a minimum can lead to the fact that the freezer practically stops freezing, acting as just a cold compartment.
In the summer, with high ambient temperatures, even the minimum settings will not allow you to completely ignore the freezer. The heat loads are high and the system will be forced to cool the entire volume to keep the food in the main compartment. In hot weather, the temperature difference between the “minimum” and “maximum” modes is smoothed out.
It is important to consider the location of the refrigerator. If it is standing near a radiator or in the sun, it will be extremely difficult to achieve the effect of a “disabled freezer”. Heat transfer will constantly provoke the compressor to turn on.
Frequently asked questions (FAQ)
Is it possible to completely turn off the freezer while leaving the refrigerator running?
In most Biryusa models with one compressor - no. They have a common cooling system. You can only increase the temperature in the freezer to the lowest possible (about -6°C) using the Holiday mode or the minimum control. A complete shutdown is only possible if you turn off the entire refrigerator from the outlet.
What does the number 0 on the thermostat mean?
The number 0 (or the “Off” position) on the mechanical regulator means a complete disconnection of the electrical circuit. At the same time, the compressor stops and both chambers, both the refrigeration and the freezer, stop working. The food will begin to defrost.
Why does the temperature not change immediately after changing the settings?
The refrigerant and air inside the chambers require time to circulate and heat exchange. Temperature stabilization after changing the thermostat settings can take from 6 to 12 hours. Do not change the settings too often, this will disrupt the automation algorithms.
Is it harmful to keep the freezer in minimum mode all the time?
No, it is not harmful. This is the normal operating mode. However, if you store foods that require deep freezing (meat, fish) in the freezer, a temperature of -6°C may not be sufficient for long-term storage, and the food may spoil faster.
How to understand that the “Vacation” mode is activated?
In models with a display, a special indicator lights up (often depicting a suitcase or the inscription Eco/Vacation). In models without a display, you need to focus on the position of the thermostat knob (minimum) and the absence of the Super Freeze function. For the exact list of indicators, see the instructions for your model Biryusa.
