The situation when Atlant refrigerator ceases to properly cool food is familiar to many owners of this popular Belarusian equipment. Instead of the usual hum of a working compressor and fresh food, you may find that the chamber has become warmer, and the ice in the freezer has begun to melt. This does not always mean that the unit has broken down completely, and often the problem can be solved without calling a technician.
The first thing you need to understand is what exactly happened: the device simply cannot cope with the load due to external factors, or a technical failure has occurred in the system refrigerant circulation. If you notice that the food in the main chamber has begun to deteriorate faster, and the “coat” of frost in the freezer has disappeared, immediate diagnosis is required. In this article we will look at how to forcibly “add cold” and return the device to functionality.
It is worth noting that different models Atlant (single-compressor or two-compressor) may behave differently in the event of failures. However, the basic principles of thermoregulation are similar. If the compressor operates continuously for more than 24 hours and the temperature does not drop below +10°C, operating the device is dangerous for the engine. Let's look at a step-by-step algorithm for restoring cold.
Diagnostics of the current temperature regime
Before turning the thermostat knobs or disassembling the back wall, you need to objectively assess the situation. It often seems to users that there is not enough cold, although in fact the equipment is operating normally, but is overloaded with warm products. Check whether the refrigerator is located next to a radiator or in direct sunlight, as this critically affects the efficiency of heat transfer.
Use an external thermometer to check the readings of the built-in sensor. Place it in a glass of water on the middle shelf and leave it for several hours. If the actual readings differ from the established ones by more than 2-3 degrees, it means that the control system has gone astray or has failed thermostat. In two-chamber models with one compressor, there is often a temperature imbalance between compartments.
⚠️ Attention: Do not try to check the temperature by placing a thermometer near the back wall of the chamber where the evaporator is located. It will always be extremely cold there, which will give a false impression of the climate in its entirety.
It is also worth listening to the operation of the engine. If it turns on too rarely or, conversely, hums continuously but does not cool, these are sure signs of a malfunction. In the first case, there may be a freon leak; in the second, there may be problems with the valves or a clogged capillary tube. Accurate diagnostics will help you choose the right method of “adding” cold.
Setting the thermostat and electromechanical control
The easiest way to add cold is to correctly set the temperature controller. In models Atlant with mechanical control (where there is a knob with numbers from 1 to 7), the principle of operation is simple: the higher the number, the lower the temperature inside. However, many users mistakenly believe that number 7 is the “maximum cold” for constant use, which leads to breakdowns.
For normal operation in summer, it is recommended to set the value 3 or 4. If you set the regulator to 6 or 7, the compressor will work non-stop, trying to achieve an unattainable ideal in the heat, which will lead to its overheating and the protective relays turning off. In winter, when the room is cool, you can safely turn the knob towards higher values.
In models with electronic control (a panel with buttons and a display), the adjustment is made more accurately. Typically, the temperature in the refrigerator compartment is set in the range from +3 to +7 degrees Celsius, and in the freezer - from -18 to -24. To change settings, press the mode button and use the arrows to make adjustments. After changing the settings, give the device 4-6 hours to stabilize the cycle.
☑️ Setting the thermostat
The system should enter a new operating mode. If, after setting the maximum permissible values, the cold has not been added during the day, then the problem lies deeper than just lost settings.
Forced defrosting as a restoration method
One of the most common reasons for the disappearance of cold is a banal “coat” of ice on the evaporator, which is located behind the back wall. In systems No Frost this may mean a malfunction of the defrosting system, and in drip models - a violation of the defrosting schedule. The ice shell works as a heat insulator, preventing cold from penetrating into the chamber.
To add cold in this case, you need to completely defrost the unit. Unplug the refrigerator, remove all food and open the doors. Leave it alone for at least 24 hours. Do not try to speed up the process with a hairdryer or hot water - this may damage the plastic case and seals, and also create a risk of short circuit.
After complete defrosting, wipe the internal surfaces with a dry cloth and turn on the device without load (empty). Let it work for 2-3 hours. If during this time a uniform layer of frost appears on the back wall (in drip models) or a characteristic defrosting crack is heard (in No Frost), then the freon circulation system is intact.
Why can’t you chip off ice with a knife?
Mechanical removal of ice with a sharp object is strictly prohibited. The evaporator walls in Atlant refrigerators are very thin (aluminum). One awkward movement will pierce the tube, the freon will instantly evaporate, and air and moisture will get inside the system. Repairs after such intervention will cost almost the same as a new refrigerator.
If after defrosting the refrigerator began to work like new, but a week later the situation repeated itself, it means that Defrost heating elementthe timer or defrost sensor has failed. In this case, you can “add cold” only by replacing the faulty part in the defrost circuit.
Checking the tightness and condition of the seals
Cold can leave the chamber as quickly as it is created if the tightness of the circuit is broken. The main reason is a worn or dirty rubber seal on the door. If the rubber is petrified, cracked, or simply does not fit tightly, warm air constantly enters the chamber and the compressor does not have time to cool it.
Do a simple test with a sheet of paper. Clamp the sheet with the door in different places around the perimeter. If the paper comes out easily, without resistance, it means that the seal is not holding in that place. Also inspect the rubber for microcracks and mold. A dirty seal should be thoroughly washed with warm water and soap, and a dry seal should be lubricated with a special silicone grease or glycerin to restore elasticity.
| Sealant problem | Symptom | Solution |
|---|---|---|
| Pollution | The door closes, but there is no cold | Washing with warm water |
| Deformation | Visible gaps, air whistling | Warming hairdryer and straightening |
| Rupture/Cracks | Obvious holes, crumbling rubber | Replacing the seal |
In some cases, if the seal has simply jumped out of the groove, you can set it in yourself using a flat-head screwdriver (carefully!) or a plastic card. However, if the rubber has lost its properties over time, only replacement will help. The new tape will provide the necessary insulation and allow the system to quickly gain cold.
⚠️ Attention: If you find that the door is warped and does not fit even with a new seal, the problem may be in the hinges. They need to either be tightened or replaced. Ignoring the misalignment will lead to rapid wear of the new seal.
Technical causes of loss of cold and their elimination
If adjustments and defrosting did not help, most likely there is a technical malfunction. The most common reason is freon leak. The refrigerant circulates in a closed circuit, and if a microcrack has formed in the tubes or radiator, the gas escapes. Without freon, the compressor wastes air, and the cold in the chamber does not increase.
Another possible reason is a clogged capillary tube. An ice or oil block may have formed in the system, blocking refrigerant circulation. In this case, the condenser (grid at the back) may be hot only at the beginning or, conversely, cold along its entire length, which is not typical for a working device. The compressor itself could also fail: it may hum, but not create the necessary pressure.
To diagnose these problems, special tools are required: a pressure gauge station to check the pressure and a leak detector. It is impossible to “add” freon yourself or clean the capillary without equipment. Attempts to do this using artisanal methods will lead to final breakdown of the unit.
If a leak or blockage is confirmed, the technician will evacuate the system, replace the filter drier and fill in a new volume of freon strictly by weight. Only after professional repairs will the refrigerator be able to freeze effectively again.
Loading rules for maximum cooling
Sometimes the problem is not in the technology, but in how you use it. A refrigerator is not a freezer; it is designed to store already chilled food. Loading hot pots or large volumes of food at room temperature creates a colossal heat load that the device cannot cope with quickly.
In addition, proper air circulation is important. If you push food close to the back wall, blocking the cold air outlet channels, “heat pockets” will form in the chamber. In areas of stagnant air, the temperature will be higher, and the food there will spoil faster, even if the sensor shows normal.
- 🥘 Cool the food: Never put hot food in the chamber, let the food cool to room temperature.
- 💨 Do not overfill: Leave gaps between the products for free air circulation flows.
- 🚪 Control the door: Do not keep the door open for more than 1-2 minutes so as not to release the accumulated cold.
- 🧊 Use a mass: An empty refrigerator holds the cold worse. Glass bottles with water help stabilize the temperature when rarely opened.
Following these simple operating rules will allow your Atlanta to work in a gentle mode and always maintain the optimal temperature without overload.
Frequently asked questions (FAQ)
Why does the Atlant refrigerator hum, but not freeze after defrosting?
If after a complete 24-hour defrosting and turning on the device hums, but the cold does not appear within 5-6 hours, there is probably a freon leak or the capillary system is clogged. The compressor could also be faulty, humming but not pumping refrigerant. A call to a technician is required to diagnose the pressure in the system.
What value should the thermostat be set in the summer?
In the summer, when the ambient temperature is high, it is better to set the mechanical thermostat to the values 2 or 3. This will allow the compressor to take sufficient rest breaks. Setting it to maximum (5-7) in the summer will lead to non-stop operation and rapid wear of the motor.
Is it possible to add cold if there is ice in the freezer and warmth in the refrigerator?
In single-compressor models, this is a common problem. This usually means that the cold air supply channel from the freezer to the refrigerator compartment is clogged, or the damper regulator is faulty. It is also possible that the damper may freeze. The air distribution system needs to be defrosted or repaired.
How long should a new refrigerator get cold?
After the first installation and switching on, the new Atlant refrigerator takes from 2 to 4 hours to reach operating mode and freeze food. During the first hours of operation, the compressor may work longer than usual, which is normal for the initial cooling of the chamber volume.
