Two-chamber refrigerators Atlant deservedly popular due to their reliability and simple design, but their correct initial setup often raises questions among new owners. The service life of the products and the unit itself directly depends on how you set the operating parameters of the compressor and distribute the air flows. Incorrect temperature in the freezer can lead to loss of vitamins in meat or, conversely, to excessive energy consumption.
In this article we will analyze action algorithms for various types of control, from mechanical thermostats to electronic display panels. You will learn why you should not load warm food and how to avoid the formation of an ice crust on the walls. Proper adjustment of modes is the key to the fact that your refrigerator will serve for many years without expensive repairs.
Design features and types of control Atlant
Before you begin adjustment, you need to determine the type of control of your model, since the logic of actions will radically different. Most two-chamber models Atlant are divided into two main groups: devices with mechanical control and units with electronic control. In the first case, you are dealing with a rotary regulator, in the second - with a touch panel or buttons.
Mechanical thermostats are usually located inside the refrigerator compartment or on the top panel of the case. They are a disk with divisions from 1 to 7 (or Min/Max). There are no exact degrees here, only relative cooling power. Electronic systems allow you to set a specific temperature with an accuracy of a degree, which ensures a more stable climate control inside the chambers.
It is also important to take into account the defrosting system. Models with No Frost in the freezer require a special approach to placing food so as not to block the ventilation holes. In drip systems (crying wall), water flows down the back wall, and here the tightness of the door seal is critical.
Initial installation and preparation for launch
After delivering the equipment home, do not rush to plug it into the network. Transport often takes place in a lying position, which could allow compressor oil to enter the refrigerant circuit. In order for the oil to drain back into the compressor crankcase, the unit must stand in a vertical position for at least 3-4 hours, and it is better to leave it overnight.
The internal space must be washed with warm water and a mild detergent to remove factory dust and the smell of plastic. Cleanliness of the internal walls is the first condition for the absence of foreign odors in the future. After washing, the doors should be left open for complete drying and ventilation.
⚠️ Attention: If the refrigerator was transported at a temperature below +5°C, plugging into the network is allowed only after 24 hours of acclimatization in a warm room. A sudden start can damage the compressor valves.
The device should be placed away from heating devices and direct sunlight. The distance to walls and furniture should be at least 5-10 cm for free air circulation around the condenser. Violation of this rule will lead to overheating and increased energy consumption.
☑️ Initial preparation of the refrigerator
Setting the mechanical thermostat
In models with mechanical control, the freezer is adjusted indirectly, through adjusting the general temperature regime. The regulator is usually located inside the refrigerator compartment (left or top) or on the top panel. Turning the knob towards large numbers increases the power of the compressor, lowering the temperature in all chambers.
The optimal position for everyday work is considered the average value, usually these are numbers 3 or 4. Position 1 (or Min) means minimal cooling, which may not be enough for a freezer in summer. The 7 (or Max) position forces the compressor to work continuously, which can result in food freezing and wear on the motor.
If you set the knob to maximum, the freezer will freeze food very quickly, but in the refrigerator compartment the temperature may drop below zero, which will spoil the vegetables. Therefore, balancing is carried out experimentally depending on the load of the chambers and the temperature in the room.
What does the red button next to the regulator mean?
This is the fast freezing button. When pressed, the compressor runs without stopping. You cannot keep it turned on for more than 24 hours - this is an emergency mode for freezing a large volume of fresh food.
Seasonality also affects the settings. In summer, when the room is hot, you may need to move the regulator closer to 4-5to compensate for heat gain. In winter, with the heating running, it is enough to leave 2-3. The main thing is not to allow the refrigerator to work at its maximum capacity all the time.
Adjusting electronic control systems
In modern models Atlant with electronics, you can independently control the temperature in each compartment. The control panel is usually located on the outside of the door or on the top end. To enter the setting mode, you often need to press and hold the temperature adjustment button for 3-5 seconds until the indicators begin to flash.
The recommended temperature for the freezer is -18°C. This value ensures long-term storage of meat, fish and semi-finished products without loss of their properties. For the refrigerator compartment, the optimal range is +2...+4°C. The electronics will automatically turn off the compressor when the specified parameters are reached.
Some models are equipped with a function Super Freeze (super freezing). This mode is activated by a separate button and makes the compressor work harder, lowering the temperature in the freezer to -24°C. You should use it only when loading a large amount of fresh products, remembering to turn it off after a few hours or wait for automatic shutdown.
| Parameter | Recommended value | Acceptable range | Impact on products |
|---|---|---|---|
| Freezer compartment | -18°C | -16...-20°C | Long-term storage, stopping bacteria |
| Refrigerator compartment | +3°C | +2...+5°C | Preserving the freshness of vegetables and dairy products |
| Freshness zone (zero) | 0°C | 0...+1°C | Storing meat and fish before cooking (1-2 days) |
| Vacation mode | +15°C | CW only | Energy saving, freezer is working, CW is off |
Rules for loading and air distribution
Even a perfectly adjusted thermostat will not save the situation if the rules for loading the chambers are violated. Cold air should circulate freely between the products. In systems No Frost ventilation holes are located on the back wall or between the shelves, and blocking them will lead to local overheating and ice formation in other areas.
Fresh, still warm food is strictly prohibited from being placed in the freezer. A sudden change in temperature will cause the compressor to work harder trying to compensate for the heat. In addition, the steam from a hot dish will instantly turn into a snow coat on the walls and products, which will worsen heat transfer.
- ❄️ Lay out the products so that there are gaps between them for the passage of air flows.
- 🥩 It is better to pre-cool meat and fish in the refrigerator compartment before deep freezing.
- 📦 Do not overcrowd the chamber - the optimal load is about 70% of the volume.
Use airtight containers or freezer bags. Opened foods quickly lose moisture (dry out) and absorb foreign odors, even in the freezer. Proper packaging is not only hygiene, but also helps the cooling system maintain a stable microclimate.
Maintenance and defrosting of the chamber
Although many models Atlant equipped with a system No Frost, defrosting cannot be completely ignored. Once every 6-12 months, it is recommended to completely defrost for washing and disinfection. This allows you to remove bacteria and mold that could settle in hard-to-reach corners.
To defrost, unplug the appliance, remove all products and leave the doors open. Do not use a knife or other sharp objects to chip ice - this is guaranteed to lead to a breakdown of the evaporator and a leak of freon. Ice should melt naturally.
⚠️ Attention: Never use a hair dryer or heating device to speed up thawing. A sudden temperature change can deform plastic parts and damage the evaporator tubes.
After defrosting, thoroughly wipe all surfaces, including the water drainage grooves (in drip systems). Make sure the drainage hole is not clogged with crumbs. Only after the refrigerator has completely dried and the smell of moisture has disappeared can you turn it on again.
Frequent problems and their solutions
Sometimes users are faced with a situation where the freezer does not freeze or, on the contrary, freezes food. If the compressor is running but there is no cold, the capillary tube may be clogged or there is a refrigerant leak. In this case, independent repair is impossible; you need to call a specialist.
If the chamber is covered with a thick layer of snow, and the food inside is soft, the problem may lie in a loose fit of the door. Check the sealing rubber for cracks and dirt. Also, the cause may be a malfunction of the defrost sensor or the evaporator heating element in the systems No Frost.
- 🛑 Humming and vibration: check if the refrigerator is touching the walls or furniture, align the legs.
- 💧 Puddle under the refrigerator: clean the drainage hole in the refrigerator compartment.
- 🔥 Hot side walls: this is a normal mode of operation of the condenser, especially during active freezing.
Continuous operation of the compressor without shutting off at normal temperature inside the chambers indicates a loss of tightness of the circuit or a malfunction of the thermostat. Operating in this mode will lead to the motor burning out, so if such symptoms are detected, it is better to stop using the device until repaired.
Why did the freezer stop freezing after defrosting?
If after defrosting the refrigerator turned on, worked for a while and turned off, but is not cooling, there may be ice left in the system that has clogged the capillary. You need to let it stand turned off for another day. If it doesn’t help, the compressor could burn out when trying to start with liquid freon (if it was turned on early).
What temperature should you set in the summer when it’s hot?
In the hot season, heat inflows are higher, so it’s more difficult for the compressor to reach the temperature. Do not set the regulator to maximum (7 or -24), this will overload it. It is better to set the average value (3-4 or -18), but check the tightness of the doors and the absence of direct sunlight on the case.
Is it possible to transport the Atlant refrigerator lying down?
The manufacturer does not recommend transportation on its side, especially where the tubes are located. If it is impossible otherwise, then you need to transport it on your right side (usually), very carefully and let it sit for at least 8-10 hours before turning it on. But the best option is only vertically.
What to do if a block of ice freezes in the freezer?
This is a sign of a broken door seal or frequent opening in wet weather. Check whether a piece of food or a bag is preventing the door from closing tightly. Also check to see if the seal is dry. If everything is ok with the seal, the defrost sensor (in No Frost) may be faulty.
