After completion of the manual process defrosting, owners often wonder: how does should behave the unit perform during the first hours of operation? Brand equipment Biryusa, which is traditionally famous for its reliability and simplicity of design, is characterized by a certain algorithm for restoring the temperature regime. Understanding these processes will help to distinguish normal operation from an incipient breakdown and avoid panic at the first start.
It is important to consider that the time to enter the mode directly depends on the model of your device, be it a classic two-chamber system or a more modern version with a system No Frost, if we are talking about newer models. On average, complete cooling of the internal volume to the specified values takes from 2 to 4 hours, but the initial start of the compressor occurs almost immediately after being turned on. At this moment, it is critical not to overload the chambers with products, giving the equipment the opportunity to create a basic temperature background.
Immediately after turning on, you may hear a characteristic hum or even a slight gurgle - this is a normal phenomenon, indicating the beginning of refrigerant circulation through the system. However, if the noise becomes unnaturally loud or is accompanied by knocking, you should listen more carefully. The first cycle of a compressor after a long period of inactivity always lasts longer than usualsince the electronics or thermostat need time to “push” the freon and cool all structural elements, including walls and shelves.
Time intervals for reaching the regime
The period of temperature stabilization is not an instantaneous process, but a sequence of physical reactions. Refrigerators Biryusa with a drip defrosting system are characterized by a gradual decrease in temperature in the main chamber. The compressor will work almost non-stop until the sensors record that the target indicators have been achieved, usually this takes about 2-3 hours.
In the freezer, the process can take up to 4-6 hours, especially if you loaded a large amount of room temperature food into it immediately after turning it on. The thermostat, receiving signals about heat, does not allow the compressor to go into rest, forcing the system to work at its limit. If after 6-8 hours of continuous operation the freezer still has not frozen the water, this is a cause for concern.
⚠️ Attention: If the compressor operates without stopping for more than 12 hours, and the temperature inside the chambers does not drop below +10...+12°C, it is necessary to stop operation and check the tightness of the system or the condition of the thermostat.
The cooling speed also depends on the ambient temperature in the room. If the room is hot (above +25°C), the refrigerator Biryusa will require significantly more time and energy to remove heat through the condenser. In such conditions, the normal cycle can increase by 30-40%, which is an absolutely normal reaction of equipment to external conditions.
Normal compressor operation and cyclicity
After the initial temperature background is established, the refrigerator goes into normal operation, characterized by cyclicity. For models Biryusa with mechanical control, a typical cycle is where the compressor runs for about 10-15 minutes, followed by a pause of 20-30 minutes. These indicators may vary depending on the load of the chambers and the temperature in the room.
Electronic control in modern models allows you to more accurately dose the engine operating time, but the principle remains the same: gaining cold and resting. If you notice that the pauses between starts have become too short (less than 5 minutes) or, conversely, the compressor turns on very rarely, but works for a long time, this may indicate disturbances in heat exchange or freon leakage.
It is important to distinguish between noise and abnormal sounds. Light hissing, gurgling and vibration of the case within reason is the norm. A loud metal clang, a high-pitched whistle, or a hum that shakes the floor requires professional attention. It is especially worth paying attention to the condition of the condenser (grid at the back), which in normal mode should be warm or hot.
Behavior of the No Frost and drip defrosting system
The algorithm for restoring operation after defrosting differs significantly depending on the type of cooling system. In classic models Biryusa with a drip system (“crying wall”), moisture begins to collect on the back wall of the main chamber already in the first hours of operation. This is a sign that the evaporator is cooling correctly.
In systems No Frost the process looks different: here moisture does not settle on the products, but freezes out on a hidden evaporator. After defrosting, such a refrigerator may make periodic clicks - this is the operation of the air damper or defrost system. If you hear these sounds, it means that the automation is functioning correctly.
| Parameter | Drip system | No Frost system |
|---|---|---|
| Time to enter mode | 2-3 hours | 3-4 hours |
| Presence of frost | On the back wall (periodically) | Absent inside the chambers |
| Noise | Low, current is audible freon | Medium, you can hear the fan |
| Humidity | High | Low |
It is worth noting that in models with No Frost immediately after Defrosting may require several cycles for the system to fully adjust the temperature balance between the freezer and refrigerator compartments. Don’t be surprised if in the first 24 hours the fan operation seems more intense.
Why might a smell appear in No Frost after defrosting?
In systems with forced air circulation after defrosting, the smell of plastic or new materials may be more actively felt, as well as the smell of products if they were not packaged. This goes away after 1-2 days of operation.
Temperature indicators and their stabilization
Temperature control is the main indicator of the health of your refrigerator Biryusa. In the refrigerator compartment, stabilization should occur in the range from +2 to +6°C. If you have a model with an electronic display, you can monitor this process in real time. Mechanical models require the use of an external thermometer for accurate diagnosis.
In the freezer, the temperature should drop to -18°C or lower. It is important to understand that the walls of the chamber can cool faster than the air in the center of the volume. Therefore, do not rush to draw conclusions in the first hour of operation - let the cold be evenly distributed throughout the entire internal space.
⚠️ Attention: Do not completely fill the chambers with products immediately after switching on. Load no more than 30% of the volume, otherwise air circulation will be disrupted and the compressor will wear out.
If you notice that the temperature in the refrigerator compartment drops below 0°C, and the food at the back wall freezes, the thermostat may be set to maximum or faulty. In models Biryusa with a mechanical adjustment knob, try setting the middle position and wait a day.
Symptoms of malfunction after startup
The first startup after defrosting does not always go smoothly. There are clear symptoms that indicate that something is wrong with the technology. First of all, pay attention to the condenser: if it remains cold while the compressor is running, this is a sure sign of a refrigerant leak or capillary tube blockage.
The second alarm signal is the formation of a “snow coat” in unexpected places or lack of cooling during continuous operation of the motor. Refrigerators Biryusa are also characterized by problems with the starting relay, if after defrosting the unit hums, clicks, but does not start.
- ❄️ The compressor works constantly, but there is no cold - a freon leak is likely.
- 🔊 A loud knock or clanging sound when starting up is a problem with the compressor or fastening.
- 💧 A puddle of water under the refrigerator is a clogged drain hole or a displaced tube.
- 🔥 Strong heating of the side walls or the grille at the back is the norm for the first hours, but if it heats up until red, there is a malfunction.
Recommendations for the initial loading of products
Correct loading of products after defrosting is the key long service to your Biryusa. Many people make the mistake of filling the chambers with warm or room temperature foods right away. This creates a colossal load on the compressor, which is already working in enhanced mode.
The optimal strategy is to wait until the empty chambers reach operating mode (2-3 hours will pass), and only then start placing products. In this case, it is desirable that the products are already chilled. If you are loading defrosted meat or fish, make sure that they are not warm.
☑️ Rules for loading after defrosting
Distribute food evenly: do not put all the heavy cans in one section and the light ones in another. This will help avoid skewing the shelves and ensure better air circulation, which is especially important for systems with forced convection.
Frequently asked questions and answers
Why does the Biryusa refrigerator not turn off for a long time after defrosting?
This is normal for the first cycle. The unit needs to cool not only the air, but also the walls, shelves and food. If this lasts more than 12 hours without a decrease in temperature, check the tightness of the door closure and the number of loaded products.
Is it possible to plug in the Biryusa refrigerator immediately after defrosting?
Yes, you can, but only after you make sure that the inside is completely dry and the water collection tray (if it is removable) is in place. It is also recommended to wait 15-20 minutes after moving the equipment before turning it on, so that the oil in the compressor flows into the crankcase.
What to do if an unpleasant odor appears after defrosting?
Rinse the internal surfaces with a weak solution of soda or vinegar. Often the smell is caused by residual water in the drainage system or forgotten food. Ventilate the chambers with the switched off for several hours.
Is it normal for the side walls of the refrigerator to be hot?
Yes, in modern models Biryusa the condenser is often built into the side walls. When the compressor is actively operating (especially after defrosting), they can heat up to 50-60°C. This is not a defect, but a feature of the heat sink.
