After purchasing a new household appliance or turning it on again after transportation, owners often are faced with alarm: the unit is working, the compressor is humming, but the desired cold inside the chambers does not occur. The question of how long the refrigerator Atlant heats up is one of the most frequently asked questions on forums and service centers. The answer to this is not always clear, as it depends on many factors, including the model of the device, the volume of the chambers and the temperature in the room.
Many users mistakenly believe that cooling should occur instantly, but the physics of the process requires time to stabilize the refrigerant in the system. Belarusian brand known for its reliability, but even the most powerful models require a certain period to reach a given mode. Understanding these time frames will help you avoid panic and unreasonable calls to the technician if the unit simply has not yet had time to “accelerate.”
In this article we will analyze in detail the time intervals for different models, consider the influence of external factors and determine the boundaries when the delay really indicates a malfunction. Technical characteristics compressor and the type of refrigerant play a key role here. We will also discuss how to properly prepare equipment for the first start-up in order to speed up the process.
Standard ramp-up time for different models
The time required for initial cooling directly depends on the volume of internal space and the power of the installed compressor unit. For most standard two-chamber models of the brand Atlant with a volume of up to 300 liters, this process takes on average from 2 to 4 hours. During this period of time, the temperature in the main chamber should drop to +5°C, and in the freezer - to -18°C.
If you are the owner of a large model, for example, a series with a large freezer volume or a three-chamber device, the waiting time increases. In such cases refrigerant circulation longer evaporator tubes require more time. You can expect the temperature in large units to stabilize within 6 and sometimes 8 hours. You should not open the doors during this period, checking the progress, as this will throw off the thermostat settings.
Models with the system deserve special attention. No Frost. In them, the process may take a little longer due to the need to cool not only the products, but also the massive plastic elements of the inner lining and air ducts. However, modern inverter compressors installed in new lines cope with this task faster than their old single-piston counterparts.
⚠️ Attention: If, after 10-12 hours of continuous operation, the temperature indicator (if any) lights up red or it is clearly warm inside the chambers, this may indicate a violation of the tightness of the circuit or a freon leak.
It is important to consider that the factory settings may differ from your expectations. Some models have an “Eco” or “Vacation” mode by default, in which the temperature does not drop to the minimum values. Check whether such a function is activated in the control unit.
Factors affecting the cooling rate
The rate of temperature rise is not a constant, but a variable value that depends on operating conditions. The first and most important factor is the ambient temperature. If the refrigerator Atlant is installed in a kitchen where it is hot (+28°C and above), the compressor will have to work with increased load to remove the heat. Under such conditions, the initial launch time can increase by 30-40%.
The second critical factor is the correct installation of the equipment. For efficient operation of the condenser, usually located on the rear wall or in the base, a free flow of air is necessary. If the unit is moved close to a wall or furniture, heat transfer it is broken. This leads not only to a long build-up of cold, but also to overheating of the motor, which shortens its service life.
It is also worth considering the quantity and temperature of the loaded products. An empty refrigerator cools down faster. If you loaded the chambers with room temperature products immediately after turning them on, the unit will require significantly more time and energy to cool them. Ideally, the initial start-up is best done with empty chambers.
- 🌡️ Room temperature: the hotter the room, the longer the compressor runs.
- 🚪 Frequency of door openings: every time you open the door, warm, humid air gets in, resetting the cooling progress.
- 📦 Load density: a full refrigerator holds the cold better, but it takes longer to initially cool a large volume of food.
The difference in the operation of models with a drip system and No Frost
Cooling technology plays a decisive role in how quickly you feel the cold. Models with drip system (Direct Cool) cool products through contact with the back wall, which periodically becomes covered with frost and then thaws. In such refrigerators, the cold is distributed unevenly in the first hours: it is already frosty at the back wall, but still warm at the door. Full stabilization takes longer due to natural convection.
The system No Frost (or Low Frost in some Atlant modifications) works on the principle of forced air circulation. The fan actively drives cold currents throughout the entire volume of the chambers. In theory, this should speed up the process. However, in practice, such models often have a more complex air duct system and additional thermal insulation layers, which can offset the speed advantage in the first hours of operation.
In addition, in models with No Frost the condition of the fan is critically important. If it does not start due to ice blockage or malfunction, the cold will not flow into the chambers, although the compressor will work. In drip systems there is no such problem, where the cold comes from the walls.
| Comparison parameter | Drip system | No Frost system |
|---|---|---|
| Operating principle | Natural convection | Forced circulation |
| Cooling uniformity | Low in the first hours | High and fast |
| Dependency on filling | High (volume required for inertia) | Average |
| Average cooldown time | 3-5 hours | 2-4 hours |
Correct first start of the Atlant refrigerator
In order for your Atlant refrigerator to reach the temperature in normal mode, you must follow the initial start-up rules. Violation of these rules can lead not only to long waits, but also to compressor breakdown. The main rule is acclimatization. If the equipment is delivered in the cold in winter, it needs to stand in a warm room for at least 3-4 hours (preferably a day) before being plugged in.
This time is needed for the condensation formed inside the electronics and the compressor to evaporate, and for the oil in the compressor to warm up and acquire the required viscosity. Switching on a cold unit is fraught with water hammer. After this, you need to wipe the internal chambers with a damp cloth and soda solution to remove factory odors.
☑️ Preparation for the first start
After connecting to the network, do not rush to load the products. Let the unit run idle for at least 2 hours. Only when you are sure that it has become cold inside can you gradually fill the chambers. A sharp load with warm products at the start will force the thermostat to keep the compressor running for days without a break.
⚠️ Attention: Never plug in the refrigerator immediately after horizontal transportation. The oil must drain into the compressor crankcase, otherwise the piston group may fail.
Diagnostics: when to sound the alarm
How to understand that the refrigerator is simply taking a long time to accelerate, and when is it time to call service? There are a number of signs that indicate a malfunction. If the compressor runs continuously for more than 24 hours, and the internal temperature is above +10°C, there is a clear problem. A working unit should gain basic cold and turn off (or go into pause mode) within the first day.
Pay attention to the operation of the motor. If it turns on for a few seconds, hums, clicks and turns off, this is a sign of problems with the start relay or a stuck compressor. In this case, you won't get cold weather. Also an alarming signal is the absence of characteristic gurgling or hissing in the evaporator tubes, which may indicate a leak refrigerant.
What to do if the compressor is hot but there is no cold?
If the compressor is running, very hot, but does not cool, most likely there is a problem Freon leak or capillary tube clogged. You can’t fix this on your own; you need to call a technician to find the leak and refill the system.
Another important diagnostic sign is ice. In models with a drip system, the back wall should be evenly covered with “snow” and droplets. If ice forms only in one corner or near the entrance of the tubes, and the rest of the wall is warm, this is a sign of a violation of freon circulation.
- 🔊 The compressor operates non-stop for more than 24 hours.
- ❄️ Inside the chambers, the temperature is above +10°C after 12 hours of operation.
- 🔥 The condenser (grid at the back) is only partially cold or warm.
- 💧 The appearance of puddles under the refrigerator or inside the chambers (not to be confused with melt water during defrosting).
Frequent errors that slow down the process
Users themselves often create conditions under which refrigerator they cannot enter the mode. The most common mistake is setting the maximum value of the thermostat immediately after turning it on. Many people turn the knob to “Maximum” or “Super Freeze”, believing that this will speed up the process. In fact, this only makes the compressor work harder, without guaranteeing quick results.
Another mistake is installing equipment near heat sources. A radiator, oven or direct sunlight heats the housing and condenser. In such conditions, the efficiency of heat removal drops to almost zero, and the unit can hum for hours, barely reaching +15°C inside.
Also, do not ignore the level. If the refrigerator is tilted, the doors may not close tightly on their own, leaving a microscopic gap. Warm air is constantly leaking through this gap, and the temperature sensor does not give the command to stop the compressor.
Summary table of time norms
For ease of perception of information, we systematize data on how much time it takes for various modifications of Atlant equipment to initially set the temperature. Remember that these values are relevant provided the room temperature is +20°C and the chambers are empty.
| Model type Atlant | Volume, l | Expected time (min) | Expected time (max) |
|---|---|---|---|
| Single-chamber | up to 150 | 60 | 120 |
| Double-chamber (old series) | 250-300 | 120 | 240 |
| Two-chamber (No Frost) | 300-350 | 180 | 300 |
| Three-chamber / Side-by-Side | 400+ | 240 | 480 |
Why does the Atlant refrigerator not reach the temperature in the freezer?
Most often the problem lies in a freon leak or a fan malfunction (in No Frost models). It is also possible that the air supply duct may freeze. If there is cold in the main chamber, but not in the freezer, this is almost always a problem with the circulation or the amount of refrigerant.
Is it possible to speed up the temperature rise by placing bottles of cold water inside?
Technically, this will help, since you will add “cold accumulators”. However, this should only be done after the refrigerator has been running for a while and it has become cool inside. A sharp temperature change (warm plastic chamber + ice bottles) in the first minutes can be stressful for the materials, but in general the method works for maintaining cold when the lights are turned off.
Does the Atlant refrigerator hum louder than usual when first started?
Yes, when first started the compressor may work louder and longer than usual, since it needs to pump oil and refrigerant throughout the system, which was previously empty (statically). There may also be noise from the expansion of the plastic box materials. If after a day the noise does not subside or knocking noises appear, this is a reason to check.
Is it necessary to defrost a new refrigerator before turning it on for the first time?
There is no need to defrost a new refrigerator, since there is no ice in it yet. However, it must be washed inside with warm water and soda to remove the smell of plastic and factory grease, and then allowed to dry.
