Starting refrigeration equipment of the brand Biryusa after transportation or long-term downtime requires compliance with a number of technical nuances, ignoring which can lead to compressor failure. Unlike some modern gadgets, there is no one universal “Start” button on the body that would instantly activate all systems. The process of activating the freezer compartment is inextricably linked with the correct setting of the temperature regime and observing the time intervals before the first connection to the network.
Users often encounter a situation where, after connecting to the power supply, the main compartment cools the food, but in the freezer the temperature remains positive. This does not always indicate a breakdown; Often the reason lies in incorrect initial settings of the mechanical or electronic regulator. Understanding the operating principles of thermostat and the features of refrigerant circulation in models of this brand will help you avoid panic and unnecessary calls to the technician.
In this article we will analyze in detail the algorithm of actions for various series of refrigerators Biryusa, including models with the system No Frost and classic drip defrosting. You will learn how to set the parameters correctly, how long to wait for the first ice to appear, and what signals indicate the need to intervene in the operation of the automation.
⚠️ Attention: If the refrigerator has just been delivered from the store in winter, it is strictly forbidden to turn it on earlier than 4-6 hours later. The condensate inside the compressor must evaporate and the oil return to the crankcase, otherwise water hammer is possible.
Preparing for the first start and checking the installation
Before wondering how to turn on the freezer, you need to make sure that the unit itself is ready for operation. Correct installation is the foundation for stable operation. The refrigerator must stand on a flat, horizontal surface. A housing misalignment of even a few degrees can disrupt the tight fit of the doors or cause improper operation of the condensate drainage system, which indirectly affects the efficiency of freezing.
It is important to provide the necessary heat exchange. The back wall of the device and the side panels (if the capacitor is built into the sides) should not be adjacent to furniture or the wall. A minimum gap of 5–10 cm is required for free air circulation. In models Biryusa with a bottom location of the freezer, overheating of the compressor due to poor ventilation often leads to the unit working for wear, but not reaching the required sub-zero temperature.
☑️ Initial startup of the refrigerator
After a visual inspection and removal of all shipping materials (adhesive tape, foam, films), you can begin connecting. The outlet must be in working order and grounded. The use of extension cords or tees is not recommended, since the starting currents of the compressor can be high, and poor contact will lead to heating of the wiring.
Setting a mechanical thermostat
In most classic models of refrigerators Biryusa the temperature is controlled using a mechanical thermostat. Usually it is located inside the refrigerator compartment, less often - on the top panel of the case. The adjustment is made by turning the knob, which has digital symbols or a scale from “Min” to “Max.”
Here it is important to understand the logic of the device: the numbers on the scale do not indicate degrees Celsius, but cooling intensity. The higher the number, the lower the temperature inside the chambers should drop. For normal operation of the freezer under normal conditions, the handle should be set to the middle position, usually this is “3” or “4”. Setting it to maximum immediately after switching on will create excess load on the compressor.
There is a common misconception that turning the knob towards maximum cold will speed up freezing products. In fact, when the regulator is set to maximum, the compressor will work without interruption, trying to reach a value that is unattainable in this mode, which will only lead to its overheating and stopping due to thermal protection, and the food in the freezer may begin to thaw due to a violation of the operating cycle.
If your refrigerator is equipped with a separate handle for the freezer compartment (in two-compressor models), the setting is made independently for each circuit. In single-compressor systems with one regulator, changing the parameter affects both compartments simultaneously, so finding a balance is critical.
Control of the electronic unit and display
Modern models Biryusa, especially series with the system No Frost, are often equipped with an electronic control module with digital display. In such units, the freezer is turned on automatically when power is applied, but requires confirmation or configuration of parameters via the control panel.
To activate the freezing mode or change the temperature, you must use touch buttons or mechanical keys on the front panel. It is often necessary to press and hold the button with the image of a snowflake or thermometer for 3-5 seconds to unlock the control panel from accidental clicks (Child Lock mode). After unlocking, the indicators on the display will light up, showing the current temperature.
| Display designation | Function | Recommended value |
|---|---|---|
| Freezer / Snowflake | Temperature freezer compartment | -18°C |
| Fridge / Drop | Refrigerator compartment temperature | +4°C ... +5°C |
| Snowflake (flashing) | Super freezing mode | Turn on temporarily |
| Lock / Lock | Button lock | Activated |
If, after turning on, all segments on the display are lit or the indicators are blinking, this may indicate a failure in the electronics or a lack of signal from the temperature sensors. In this case, you should try turning off the power to the device for 10–15 minutes to reboot the controller. Electronics Biryusa are sensitive to power surges, so the presence of a surge protector is desirable.
Features of activating the No Frost system
Refrigerators Biryusa s system No Frost ("Without frost") do not require manual defrosting, since moisture is removed by evaporation through a special heater. However, immediately after switching on in such models, the cold does not begin to be produced instantly. The system must go through a full cycle of testing and initial cooling, which can take up to 12–24 hours.
Unlike static systems, where cold air falls down, No Frost uses a fan that forcibly circulates air flows. If you turn on the refrigerator, but the freezer does not freeze in the first couple of hours, this is normal. The fan may turn on cyclically. It is important not to load the chamber with products during this period, so as not to interfere with the formation of the correct temperature background.
⚠️ Attention: In No Frost models, it is strictly forbidden to seal the ventilation holes inside the chambers with products. This will disrupt the air circulation, and the temperature sensor will show the wrong temperature, which is why the freezer may not turn on at full capacity.
Checking the operation of the system is carried out visually: a day after turning on there should be no ice or snow on the walls of the freezer, and the temperature should be stable at -18°C. If frost increases, the defrosting heating element or sensor may be faulty, and “turning on” the freezer in normal mode is impossible without repair.
Waiting time and temperature conditions
One of the most frequently asked questions: how long after turning on does the chamber begin to freeze? For refrigerators Biryusa, as for most household models, it is considered normal to reach operating mode within 2 hours. However, complete freezing of the entire volume, especially if the chamber was empty, can take up to 6–8 hours.
If you loaded a lot of warm products at the same time, the temperature stabilization time increases. In such cases, it is advisable to use the “Super Freeze” function (if provided by the model). This mode forcibly turns on the compressor for continuous operation for several hours, ignoring standard shutdown cycles.
Why does it take a long time to gain temperature?
If the refrigerator is in an unheated room at a temperature below +10°C, it may not turn on at all or work ineffectively. In such conditions, the refrigerant does not circulate well, and the oil in the compressor thickens. Operation at low ambient temperatures is prohibited by the instructions.
It is best to control the process using an external thermometer placed in a glass of water inside the freezer. Mechanical thermostats inside the housing may have an error, so you should only trust the actual readings after a day of operation. The range from -18°C to -24°C is considered normal.
Diagnostics: why the freezer does not turn on
If more than a day has passed, and it is warm in the freezer, it is necessary to carry out diagnostics. First of all, check if the compressor is working. If it hums, but there is no cold, there may be a freon leak. If the compressor is silent, but the light in the refrigerator is on, the problem may be in the thermostat or the start relay. Biryusa warm, it is necessary to carry out diagnostics. First of all, check if the compressor is working. If it hums, but there is no cold, there may be a problem clogged capillary tube or freon leak. If the compressor is silent but the refrigerator light is on, the problem may be with the thermostat or the start relay.
In models with one compressor, a situation often occurs when the refrigerator compartment works well, but the temperature in the freezer is above zero. This may indicate a malfunction of the damper (in No Frost systems) or an imbalance of the refrigerant. It is also worth checking the door seal: if it does not fit tightly, warm air constantly enters and the system cannot cope with cooling.
- 🔌 Checking the voltage: Make sure that the network voltage is stable. At low voltage, the compressor may hum, but not start.
- ❄️ Presence of frost: A uniform layer of frost on the evaporator (visible during defrosting) indicates the presence of freon. If the tube is clean or covered with frost only at the entrance, a leak is likely.
- 🔊 Operation sounds: Gurgling and hissing are normal sounds of freon circulation. Complete silence when the fan is running is a sign of problems with the refrigerant.
⚠️ Attention: Opening the refrigerator circuit yourself or trying to add freon without special equipment and a license is prohibited. This is life-threatening and will permanently damage the equipment.
Frequently asked questions (FAQ)
Is it possible to turn on the Biryusa refrigerator immediately after delivery?
No, if the refrigerator was transported lying down or at sub-zero temperatures, it is necessary to let it stand vertically for at least 4-6 hours (preferably 24 hours) for the oil to drain into the compressor and equalize the temperatures.
What number should be set on the thermostat in the summer?
In the summer, when The ambient temperature is high, it is recommended to set the regulator to values “3” or “4”. This will ensure sufficient cooling without overloading the engine. Use the “Max” mode only for quick freezing.
Why is the temperature indicator flashing on the display?
A flashing indicator usually indicates that the temperature in the chamber is above the set norm. This is normal in the first hours after switching on or after loading a large batch of products. If the blinking does not stop for a day, call the service.
Do I need to defrost the No Frost freezer?
The No Frost system involves automatic removal of moisture, but sanitary defrosting and washing of the chamber is recommended at least once a year to remove bacteria and odors.
