The situation when Atlant refrigerator ceases to cope with the main function and products begin to deteriorate is familiar to many owners of this equipment. Instead of the usual hum of a working compressor, you may notice that the unit operates almost silently or, conversely, hums nonstop, but there is no desired cold inside the chambers. This is a critical moment that requires immediate diagnosis, since long-term storage of products at elevated temperatures can lead to food poisoning and financial losses.
Often users mistakenly believe that the problem lies solely in a compressor failure or refrigerant leak, and call a technician without checking the basic settings. However, in most cases reason for poor cooling it is trivial: incorrect installation, contamination of the heat exchanger, or incorrect settings of the temperature controller. Understanding the principles of operation of your model will help save time and money when calling a specialist.
In this article we will analyze in detail all the possible reasons why Atlant refrigerator it freezes poorly, and we will offer step-by-step instructions for troubleshooting. We will look at both simple steps that can be completed in 5 minutes, and complex technical problems that require professional intervention. Carefully follow the recommendations to return your unit to its previous power.
Checking and adjusting the temperature regulator
The first thing to do when insufficient cold is detected is to check the position of the temperature regulator. In models Atlant with electromechanical control, this is a rotary handle, usually located inside the refrigerator compartment on the side wall or on the ceiling. The numbers on the scale do not indicate degrees Celsius, but indicate the intensity of the compressor: the higher the number, the lower the temperature inside the chamber.
If the knob is set to the minimum value (usually “1” or “Min”), the compressor will turn on rarely and operate in short cycles, which is not enough for high-quality freezing of food in hot weather or when the chambers are fully loaded. The optimal mode for everyday work is considered to be position “3” or “4”. Moving the regulator to the “Max” or “5-7” position makes the unit work almost non-stop, which may be necessary in the summer, but requires control.
⚠️ Attention: Setting the regulator to maximum cooling (“Max”) leads to increased energy consumption and accelerated wear of the compressor. Use this mode only for a short time to quickly freeze a large volume of food.
In models with electronic control, the setting is made through a panel on the door or inside the chamber. Here you set specific degrees. For the refrigerator compartment, the range is considered to be from +2 to +4 °C, and for the freezer - from -18 to -24 °C. If, after changing the settings, the temperature does not stabilize within 2-3 hours, perhaps the problem is not in the settings, but in a technical malfunction.
The influence of operating conditions and placement
The location of the refrigerator plays a huge role in the efficiency of its operation. Atlant refrigerators, like any other equipment, they require free space for air circulation around the heat exchange radiator (capacitor), which is usually located on the rear wall. If the unit is moved close to the wall or built into a niche without gaps, the heat removed does not have time to dissipate, and the cooling efficiency drops.
In addition, it is important to take into account external heat sources. Placing the refrigerator next to a gas stove, oven, radiator, or in direct sunlight creates extreme operating conditions. In such cases, the compressor is forced to work at the limit of its capabilities, trying to compensate for external heat, but often simply cannot cope with the task. This is especially true for older models with a single-circuit cooling system.
Check the following installation parameters of your device:
- 🔥 The distance to the nearest wall should be at least 5-7 cm for free air convection.
- ☀️ Make sure that the case is not exposed to direct sunlight, which heats up metal surfaces.
- 🍳 Do not install the refrigerator closer than 50-60 cm from sources of open fire or powerful heating devices.
Diagnostics of the No Frost and defrosting
Owners of models Atlant with the system No Frost (or “Crying evaporator” in new modifications) may encounter a problem when the refrigerator is humming, the light is on, but there is no cold. A common cause is the formation of an ice “coat” on the evaporator hidden behind a plastic panel. Ice blocks the circulation of cold air, and it simply does not enter the main chamber.
The automatic defrosting system may fail due to a malfunction of the heating element, timer or defrost sensor. As a result, the ice grows and turns into a monolithic piece that blocks the air ducts. Visually, the chamber may be clean, but there is a block of ice hidden behind the back wall. A symptom may also be that the freezer freezes normally, but the refrigerator compartment is warm.
To eliminate this problem, completely defrost the unit:
- Disconnect the refrigerator from the power supply.
- Take out all the food and remove the shelves.
- Leave the doors open for at least 24 hours (preferably for a day so that the ice inside completely melts).
- Wipe the internal surfaces dry before turning them on.
☑️ Correct defrosting algorithm
If, after completely defrosting and turning on, the refrigerator begins to freeze poorly again after a few days, then the problem lies in one of the elements of the defrosting system, and replacement of parts is required.
Problems with sealing rubber bands
The tightness of the chambers is the key to the efficient operation of any refrigerator. If the sealing rubber (cuff) on the door is worn out, dirty or deformed, warm air from the room constantly enters the chamber. The compressor tries to compensate for the heat gain by working without interruption, but the temperature inside does not drop to the required values. This is a classic situation when the refrigerator works, but does not freeze.
You can check the condition of the seal by simple visual inspection and tactile inspection. The rubber must be clean, elastic, without cracks, tears or sticky residue. Often the problem is solved by simply washing the rubber with warm water and soap, since grease and dirt prevent the door from fitting tightly to the body.
For a more accurate diagnosis, use a test with a sheet of paper:
- 📄 Take a regular sheet of A4 paper.
- ❄️ Place it between the door and body in different places around the perimeter.
- 👐 Try to pull the sheet out: if it slips out easily or falls out on its own, the seal is broken.
⚠️ Attention: If the rubber has lost its elasticity and has become hard (“stiff”), washing will not help. In this case, a complete replacement of the seal is required, since it is almost impossible to restore the properties of old rubber.
Also check the door hinges. Over time, they can weaken and cause the door to warp, creating a gap at the bottom or top. Adjusting the hinges often solves the problem of a loose fit without replacing consumables.
Technical faults: freon, compressor, capillary
If all of the above methods did not help, and Atlant refrigerator it still does not freeze, a serious technical breakdown is likely. The most common reason is refrigerant (freon) leak. Freon circulates through the tube system and picks up heat. If there is little of it due to a microcrack in the circuit, the cooling capacity drops. Signs of a leak: the compressor is running constantly, the condenser (grid at the back) is only partially warm or cold, there is no ice in the freezer.
The second common problem is a clogged capillary tube. Oil circulates in the system, which over time can thicken or mix with wear debris, forming a plug. Freon cannot pass through the narrow section of the tube, circulation stops, and no cold is produced. The symptoms are similar to a leak, but the compressor may overheat.
The third reason is failure of the compressor itself. It may “jam” or lose power (not hold pressure). In this case, a characteristic click is heard when trying to start, a buzzing sound, but there is no start, or it works, but does not create the necessary pressure in the system.
| Symptom | Probable cause | Nature of the compressor operation | Temperature condenser |
|---|---|---|---|
| No cold in both chambers | Freon leakage | Works without stopping | Cold or partially warm |
| The freezer is freezing, the refrigerator compartment is - no | System malfunction No Frost / clogged | Works cyclically | Hot |
| Weak cold, long cycle | Clogged capillary tube | Operates with overheating | Hot to the middle |
| The cold disappears periodically | Thermostat malfunction | Does not turn on or off | Changes |
Is it possible to refill freon yourself?
Refilling freon yourself at home is highly not recommended. This requires a vacuum pump, a pressure gauge station and precise knowledge of the type and weight of the refrigerant. An error in dosage or moisture entering the system will lead to the final failure of the compressor.
When you need to call a technician
There are a number of situations when attempts at self-repair are not only useless, but also dangerous. If you suspect a freon leak or a clogged system, special equipment is required for diagnostics, evacuation and refilling. Opening a sealed circuit without skills and tools is guaranteed to lead to damage to the refrigerator.
Also, a master is needed if:
- 🛠 The compressor hums, clicks, but does not start (replacement of the starting relay or the motor itself is required).
- 💧 Traces of oil are visible inside the chamber (a sign of depressurization).
- 🔌 The smell of burning or scorched wiring is heard.
- 📉 After defrosting, the problem returns after 1-2 days (the defrosting system is faulty).
Contacting professionals in these cases is the only rational solution. The technician will conduct diagnostics using a leak detector, determine the exact location of the leak or breakdown and perform high-quality repairs with a guarantee.
⚠️ Attention: Prices for refrigerator repairs may vary depending on the cost of components and the complexity of the work. Before starting repairs, be sure to agree on the final cost with the technician and find out the guarantee for the work performed.
Frequently asked questions (FAQ)
Why does the Atlant refrigerator freeze only near the back wall?
This is normal for models with a “crying” evaporator. The back wall is the cooling element. Cold air is distributed throughout the chamber due to natural convection. If food is placed close to the back wall, it may freeze, but the center of the chamber will be warmer. Try to leave a gap between the food and the back wall.
How long should a new Atlant refrigerator cool down after switching on?
Complete cooling of an empty refrigerator to the specified parameters usually takes from 2 to 6 hours, depending on the ambient temperature in the room. Loading with products should be done only after the unit has completed one full cycle and automatically turns off. Loading with warm food will increase this time.
Can the refrigerator not freeze due to power surges?
Yes, power surges can damage the compressor start relay or control electronics. If your network has unstable voltage, it is recommended to use a stabilizer. Also, after a power outage, do not turn on the refrigerator immediately, let it stand for 10-15 minutes.
What to do if there is ice in the freezer, but it is warm in the refrigerator?
Most likely, air circulation is disrupted. Check that the ventilation holes are not clogged with food. If you have a No Frost system, you probably need a complete defrost (at least for a day) to remove the ice plug in the channel or evaporator.
What is the normal temperature in the Atlant refrigerator compartment?
The optimal temperature for storing most products in the main chamber is from +2 to +5 degrees Celsius. In the freshness zone (if there is one), the temperature can be about 0 degrees. In the freezer, the temperature should not be higher than -18 degrees.
