After purchasing and delivering a new one household appliance owners often wonder: how long does the Atlant refrigerator take to get cold for the first time? This process does not happen instantly, as it might seem at first glance. The compressor takes time to circulate the refrigerant through the system and cool the internal chambers to the specified parameters. Usually this period takes from several hours to a day, but the exact time depends on the specific model and operating conditions.
There is a common misconception that the unit is ready for use immediately after being plugged into the outlet. In fact, initial start-up requires special attention to installation details and temperature conditions. If you just brought the device back from the store, especially in winter, it may need acclimatization. Ignoring this stage may lead to compressor breakdown or incorrect operation of the defrosting system.
In this article we will look in detail at why the equipment does not freeze immediately, how the type of defrosting system affects the cooling rate and what factors can slow down this process. You'll learn when to download products and how to know if your device is working properly. Correct operation from the first minutes will extend the service life of your Atlanta and ensure the safety of products.
Factors influencing the cooling rate of the chambers
The time it takes for the refrigerator to reach operating temperature directly depends on several technical and external factors. First of all, you should take into account the volume of the chambers and the power of the installed compressor. The larger the displacement of the device, the longer it takes the motor to circulate the refrigerant throughout the entire circuit. The initial temperature inside the chambers also plays a role: if you have just defrosted the unit or it was standing in a warm warehouse, the process will take longer than when turned on again.
The most important parameter is type of refrigerant and the design of the evaporator. Modern models are often filled with environmentally friendly gas R600a (isobutane), which has excellent thermodynamic properties, but requires more precise dosage and evacuation of the system during repairs. Older models using R134a freon may behave slightly differently. In addition, the ambient temperature (room temperature) significantly affects heat transfer: in a hot kitchen in the summer, the refrigerator will work harder and take longer to gain cold.
⚠️ Attention: If you transported the refrigerator lying down or at sub-zero temperatures, be sure to let it stand upright for at least 4-8 hours before turning it on. The oil in the compressor must drain into the crankcase, otherwise water hammer and engine failure are possible.
Do not forget about the tightness of the seals. If the door does not fit tightly, the cold will escape and warm air will flow in, causing the compressor to run idle. Check to see if anything is preventing the door from closing immediately after installation. The speed is also affected by the number of loaded products: an empty refrigerator will cool down faster, but will hold the temperature less effectively when opened.
Time difference for the No Frost and drip system models
One of the key points that determines how long the Atlant refrigerator will start to freeze is the defrosting system used. Devices with drip system (or "crying evaporator") usually cool faster in the initial phase. In such models, moisture condenses on the back wall, freezes and periodically thaws, flowing into the drain. The first cooling cycle in them can take about 2-4 hours until stable values are reached.
Models with the system No Frost (or Full No Frost) are more complex. In them, air circulation is forced with the help of a fan, which ensures uniform temperature at all points of the chamber, but requires more time for initial startup. The air must cool, passing through the hidden evaporator, and then spread throughout the entire volume. For such units, the normal time is from 4 to 8 hours until the mode is completely stabilized.
Below is a comparative table showing the approximate time to reach the mode for various types of devices:
| System type | Approximate time to -18°C | Features of the first cycle |
|---|---|---|
| Drip (Static) | 2 - 4 hours | Rapid cooling of the rear wall |
| No Frost (refrigerator compartment) | 3 - 5 hours | Uniform distribution of flows |
| Full No Frost (two chambers) | 6 - 10 hours | Long-term freezer stabilization |
| Combined | 4 - 6 hours | Depends on the priority of the cameras |
It is worth noting that the indicated time intervals are relevant provided that the device was installed according to the instructions. If you violated the transportation rules or the ambient temperature is too high, these deadlines may increase. In some cases, a full cycle of freezing a large volume of food in the freezer No Frost can take up to 24 hours.
Why a new refrigerator does not freeze immediately
The situation when a new one is turned on, but the cold does not come out, often causes panic among buyers. However, in most cases this is completely normal. Modern refrigerants, especially isobutane, require time to build up the required pressure in the system. The compressor may work intermittently, turning on and off until the sensors record the desired temperature. Atlant turned on, but the cold does not come out, often causing panic among buyers. However, in most cases this is completely normal. Modern refrigerants, especially isobutane, require time to build up the required pressure in the system. The compressor can work intermittently, turning on and off until the sensors record the desired temperature.
Another reason for the delay may be the operation of the electronic control module. In smart models with a display and many functions, the initial startup is accompanied by self-diagnosis and sensor calibration. The device may not start the compressor at full power immediately to avoid overloading the electrical circuit and mechanical parts. This is part protection algorithmof the protection algorithm provided by the manufacturer.
It is also important to check whether the settings are set correctly. Sometimes at the factory the temperature regulator is set to the minimum position or in the "Transport" mode (Off). You need to set the desired mode yourself. If you use electronic control, make sure that the fast freezing function is not activated unnecessarily, as it can work cyclically.
⚠️ Attention: If after 10-12 hours of operation the compressor does not work at all (does not make sounds, does not heat up at the back) or, on the contrary, works without stopping for more than a day without cooling the chambers, this is a reason to contact the service. Do not try to disassemble the cooling system yourself.
☑️ Check before loading food
Temperature standards and operating modes of the compressor
Understanding how the compressor works will help you not worry unnecessarily. In normal mode work cycle it looks like this: the motor turns on, pumps in cold, reaches the set temperature and turns off. Then, when the temperature rises a few degrees (heat gain), the cycle repeats. On the first day, cycles may be longer and pauses shorter.
The optimal temperature in the refrigerator compartment is considered to be from +2 to +5 degrees Celsius. In the freezer, the standard is -18 degrees and below. If your Atlant thermometer shows +10 degrees after 5 hours of operation, this is not yet a cause for alarm, especially if the chamber is warm. However, if after a day the temperature does not drop below +10, it is worth checking the tightness of the door and the amount of loaded products.
There are special modes that affect the cooling rate. For example, the Super Freeze mode causes the compressor to run continuously for several hours, ignoring standard shutdown cycles. This is useful when loading large quantities of fresh products, but is not recommended for constant use, as it increases wear on the motor.
⚠️ Attention: Characteristics and operating algorithms may vary depending on the specific series and year of manufacture of the model. Always check the official instructions (operating manual) supplied with your device, as manufacturers may make changes to the design.
Why do the side walls get hot?
In modern models of Atlant refrigerators, the condenser (heat exchanger) is often built into the side walls of the case, and not located at the back in the form of a grill. Therefore, heating the sides to 40-50 degrees in the first hours of operation or during active freezing is absolutely normal and indicates effective heat removal.
What to do if the cold does not accumulate for a long time
If more than 24 hours have passed and it is still warm inside the refrigerator, you need to carry out independent diagnostics. First of all, check if the compressor is working. Place your hand on the back grill or side walls - they should feel warm or hot. If the motor is humming, but there is no heat anywhere, and there is no cold inside either, the capillary tube may have become clogged. a freon leak or clogged capillary tube.
The second step is to check the tightness. Take a sheet of paper, clamp it with the door and try to pull it out. If the sheet is pulled out too easily without resistance, it means that the seal is not tight. Also inspect the rubber itself for cracks, creases, or dirt that would prevent it from sealing tightly. Sometimes the problem is solved by simply adjusting the door hinges.
The third aspect is the serviceability of the thermostat or sensors. If the device “does not see” that the chamber is warm, it simply will not turn on the compressor. In mechanical models, you can try turning the thermostat knob from minimum to maximum and back, listening for a click. In electronic models, you may need to reset the settings or diagnose an error on the display.
Frequent errors when starting up equipment for the first time
Many problems with setting the temperature arise due to trivial user errors during installation. One of the most common is installing the refrigerator too close to the wall or in a niche without gaps. For normal operation, the system needs heat transfer environment. If the air gap between the back wall and the furniture is less than 5 cm, the cooling efficiency drops critically.
Another mistake is loading a large amount of warm products immediately after switching on. The refrigerator is not an industrial-scale freezer; it is designed for storing already chilled food. Trying to freeze 5 liters of hot soup in the first hour of operation can “kill” the compressor or lead to long downtime without results.
Also, users often forget to remove the transport locks. Although they are less common in refrigerators than in washing machines, some models may have locking features on shelves or drawers that interfere with air circulation inside. Be sure to remove all packaging material, including tape and film from internal elements.
- 🚫 Error: Installation near a radiator or stove. Solution: Keep a distance of at least 50 cm from heat sources.
- 🚫 Error: Frequent opening of the door in the first hours. Solution: Let the equipment calmly gain cold without intervention.
- 🚫 Error: Ignoring the level floor. Solution: Adjust the legs so that the refrigerator is stable and the door closes itself.
Is it possible to speed up the cooling process?
The only safe way is to ensure ideal ventilation around the housing and do not open the doors. Using fans to blow air through the rear grille is theoretically possible, but is not recommended by manufacturers due to the risk of dust and moisture getting into the electrics. It’s better to just be patient.
When you can load food after turning it on
The main rule is: you can load food only after the refrigerator is in operating mode. How to determine this moment? The easiest way is to use a thermometer, placing it in a glass of water in the central part of the refrigerator. If after 4-6 hours the water temperature is +4...+5 degrees, the device is ready for use.
It is better to load products gradually. Fill about 50% of the volume first so as not to create a sudden thermal shock to the system. After a few hours, when the temperature has stabilized after the first addition, you can add the rest. Remember that a full load requires more cooling time than running an empty unit.
Pay special attention to the freezer compartment. If you plan to freeze meat, berries or semi-finished products, make sure that the temperature in the freezer has reached at least -18 degrees. Quick freezing preserves the structure of products and their beneficial properties, and this is only possible with a working and fully operational system No Frost or freezer compartment.
- ✅ Tip: Distribute the products evenly without closing the ventilation holes inside the chamber.
- ✅ Tip: Do not place warm dishes next to already chilled foods.
- ✅ Tip: Use containers for better air circulation and hygiene.
How long should the Atlant refrigerator sit after transportation in winter?
If the refrigerator was delivered at a temperature below +10 degrees, it needs to stand in a warm room, turned off, for at least 8-12 hours (preferably a day). This is necessary so that the condensation formed inside the electronics evaporates, and the oil in the compressor warms up and becomes fluid. Turning on a frozen unit can lead to breakdown.
Are humming and gurgling sounds normal?
Yes, absolutely. The sounds of bubbling, liquid flowing and humming of the compressor indicate that refrigerant is moving through the system. Modern models with inverter compressors may have a quieter sound, but there are no completely silent refrigerators. Only a loud knock, clanging or piercing whistle should alert you.
Why does ice form on the back wall of the refrigerator compartment?
In models with a drip system, this is part of the operating cycle. The moisture freezes on the evaporator (back wall), turning into a “fur coat”. When the compressor turns off, the wall thaws and water flows into the drain hole. If the ice grows in huge layers and does not melt, the defrost sensor may be faulty or the drainage is clogged.
Is it possible to connect the refrigerator to the network via an extension cord?
Manufacturers do not recommend using extension cords, especially cheap ones or rolled ones. A refrigerator is an energy-intensive appliance, and when the compressor starts, current surges occur. A poor connection in an extension cord can cause heat, sparks, and even fire. If you cannot do without an extension cord, use only a high-quality surge protector with grounding and a current rating of at least 16A.
What to do if the temperature alarm indicator is on?
The indicator (frequently flashing or red) lights up if the temperature in the chamber is higher than normal. This is normal in the first hours after switching on. If it lights up constantly after a day, check whether the door is tightly closed, whether the refrigerator is overloaded and whether the mode is set correctly. If everything is in order, diagnostics of the sensors may be required.
