Correct operation of the freezer compartment directly affects the shelf life of your products and energy consumption of equipment. Refrigerators Atlant are famous for their reliability, but to preserve the taste of meat, fish and vegetables, it is necessary to accurately set the temperature. Incorrect settings can lead either to freezing of products, turning them into an ice stone, or to spoilage of supplies due to insufficient cold.
In this article we will analyze all the nuances of temperature adjustment in models with manual control and system No Frost. You will learn how to interpret thermostat readings, what the numbers on the scale mean, and when professional intervention is required. The correct equipment is the first step to saving the family budget on electricity. Calibration Many users mistakenly believe that the more you turn the regulator knob, the better. This is not always the case. Excessive load on calibration equipment is the first step to saving the family budget on electricity.
Many users mistakenly believe that the more you turn the control knob, the better. This is not always the case. Excessive load on compressor reduces its service life, and products may lose structure. Let's figure out how to find the “golden mean” for your refrigerator Atlant.
The principle of operation of the thermostat in Atlant refrigerators
The main element of temperature control in most models Atlant is a mechanical thermostat. It is a device that opens the electrical circuit of the compressor when the set temperature inside the chamber is reached. On the front panel of the refrigerator there is usually a rotary knob with a digital designation or a scale from 1 to 7 (or from Min to Max). It is important to understand that the numbers on the scale do not mean degrees Celsius.
The higher the number you set, the lower the temperature inside the chamber will be. For example, position “1” means minimum cooling (warmest mode), and position “7” means maximum freezing. In some models with electronic control, instead of a knob, a digital display is used where you set specific degree values, which greatly simplifies control the process.
The thermostat reads the temperature through a special sensitive element, which can be located inside the chamber or taken outside (in older models). When the air is heated above a set threshold, the contacts close, starting the motor. When the air cools, the circuit opens. The accuracy of this process depends on the serviceability of the seal door and the absence of heat inflows.
- ❄️ The number “1” corresponds to the warmest operating mode of the refrigerator.
- ❄️ The number “7” or “Max” means intensive freezing mode.
- ❄️ Position “0” or “Off” completely disables cooling.
- ❄️ Electronic models allow you to set the exact temperature in degrees.
⚠️ Attention: Abruptly moving the thermostat knob from minimum to maximum can lead to water hammer in the refrigerant system. Change the settings smoothly, at intervals of 30-60 minutes.
Understanding the physics of the process helps to avoid common mistakes. If you have just loaded a large amount of food at room temperature into the freezer, turning on the mode for a short time is super-freezing justified. However, it is impossible to keep equipment in this mode all the time.
Optimal temperature conditions for storage
Each type of product has its own requirements for storage conditions. In the freezer compartment of the refrigerator Atlant the temperature should be stable. According to international standards, for long-term storage (up to 1 year) the temperature should be -18°C or lower. With this mode, the growth of bacteria stops and chemical reactions in products slow down.
If you plan to store supplies for no longer than 3 months, an increase in temperature to -12°C is permissible. However, for poultry and minced meat, it is better to stick to lower values. The “super freeze” mode (usually indicated by a snowflake or a button with a snowflake icon) allows you to quickly cool fresh food to -24°C, preventing the formation of large ice crystals that destroy the cellular structure.
| Storage mode | Temperature (°C) | Shelf life (approximate) | Suitable products |
|---|---|---|---|
| Long term | -18...-24 | up to 12 months | Meat, fish, berries |
| Medium term | -12...-18 | up to 3-4 months | Semi-finished products, vegetables |
| Short-term | -6...-12 | up to 1-2 weeks | Ready meals, bread |
| Refrigeration | 0...-2 | up to 3 days | Fresh meat (before cooking) |
Do not fill the freezer to capacity. For normal air circulation it is necessary to leave free space between products. In models with a system No Frost this is especially important, since cold air should evenly wash all supplies.
Instructions: how to set the temperature manually
The setup process depends on the control type of your model. In classic refrigerators Atlant (for example, series 40, 42, 45), adjustment is made mechanically. Find the thermostat knob, which is usually located inside the refrigerator compartment on the top wall or on the outside of the case in the upper part.
If you want to change the temperature in the freezer, you need to turn the knob to the appropriate position. Remember that changing the settings in the refrigerator compartment also affects the freezer in single-compressor models. For two-compressor models Atlant (series 60, 62) there are often separate regulators for each chamber, which allows you to adjust independent temperature conditions.
☑️ Temperature setting algorithm
After you have changed the position of the handle, do not expect an instant result. The refrigerator needs time (usually from 2 to 5 hours) to stabilize the internal climate and reach a new one. Only after this time can conclusions be drawn about the correctness of the setting. temperature mode. Only after this time can we draw conclusions about the correctness of the settings.
- 🌡️ Turn the knob clockwise to increase the cold.
- 🌡️ Turn the knob counterclockwise to weaken cooling.
- 🌡️ Avoid setting the regulator to extreme values unless necessary.
⚠️ Attention: If the temperature in the room where the refrigerator is located is below +10°C or above +32°C, the standard setting may not work correctly. In such conditions, the compressor may not start or work without stopping.
Setting up Atlant refrigerators with the No Frost system
Models Atlant with the system No Frost (for example, the XM 4425, XM 6025 series) have their own characteristics. There is no frost on the walls, and the temperature is distributed more evenly due to forced air circulation. The control in such models is often electronic, with information displayed on the display on the door.
To adjust the temperature in models with electronics, use the control buttons on the panel. Usually there are separate buttons for the refrigerator (Fridge) and freezer (Freezer) chambers. By clicking on them you change the digital value on the display. The optimal setting for the freezer is -18°C, and for the refrigerator compartment - +3...+5°C.
What is Holiday Mode in Atlanta?
Holiday mode is intended for long departures. In this mode, the refrigerator compartment switches to an economical mode (about +15°C), preventing the formation of mold, and the freezer continues to operate normally to preserve frozen food.
It is important to monitor the cleanliness of the air channels in the system No Frost. If you notice that the temperature has ceased to hold, check whether the food has blocked the outlets for cold air. Unlike the drip system, here the disruption of circulation immediately affects the efficiency freezing.
- 🔹 Use the "+" and "-" buttons to change the values.
- 🔹 Hold the button for 3 seconds to activate the child lock.
- 🔹 Watch the alarm indicators on the display.
Quick freezing mode and its effect
The Super Freeze function is a powerful tool that should be used with caution. When this mode is activated, the refrigerator compressor Atlant begins to work continuously, ignoring thermostat shutdown signals. This allows you to quickly reduce the temperature in the chamber to minimum values.
It is recommended to use this mode only when loading a large volume of fresh, non-frozen products. This helps preserve their structure and nutrients. However, if you forget to turn off this mode, the compressor may overheat, and the products in the already frozen layer may freeze, becoming dry and tasteless.
In mechanical models, the mode is often turned on by a separate button with an indicator (lights up yellow or red). In some older models, to turn on the “super freeze”, the thermostat knob had to be moved to the far right position. In modern electronic versions, just click the corresponding icon on the panel.
⚠️ Attention: Do not turn on the Quick Freeze mode if the freezer compartment is already completely filled with frozen food. This will lead to wasted energy consumption and wear on the compressor.
Typical problems and their solutions
Even with correct settings, users may encounter problems. For example, a “snow coat” may form in the freezer, although the system assumes its absence, or, conversely, food begins to thaw. Often the reason lies not in a breakdown, but in a violation of operating rules. Atlant a “snow coat” may form, although the system assumes its absence, or, conversely, the products begin to thaw. Often the reason lies not in a breakdown, but in a violation of operating rules.
If the temperature in the chamber is higher than normal, check the tightness of the seal sealing rubber on the door. Warm, moist air enters the chamber through a loosely closed door, which condenses and freezes. Also, the cause may be a clogged drainage hole through which condensate is removed.
In cases where the refrigerator operates without stopping and the temperature does not drop to the set temperature, there may be a leak refrigerant or the thermostat has failed. Self-adjusting the handle in this case will not help - you need to call a specialist for diagnostics.
- 🔧 Check whether the refrigerator's back wall is close to the wall (a gap of 5-10 cm is needed).
- 🔧 Make sure that the products do not block the air flow from fan.
- 🔧 Clean the condenser (grid at the back) from dust and animal hair.
Frequently asked questions (FAQ)
Which number on the Atlant thermostat is considered normal for everyday use?
For everyday use at standard room temperature (+20...+25°C), the optimal position of the thermostat knob is considered to be “3” or “4”. This provides a balance between high-quality cooling and economical energy consumption. In the summer, when the apartment is hot, you can shift the regulator one notch towards increasing the cold (closer to 5).
Why does ice freeze in the Atlant freezer if there is no water?
Ice (snow coat) is formed from moisture contained in the air and the products themselves. If you put warm food in the chamber or open the door frequently, the humidity will rise sharply. In models without No Frost this inevitably leads to the freezing of ice, which must be periodically removed by defrosting. In No Frost systems, ice indicates a defrost malfunction or poor door fit.
Is it possible to store food in the freezer at a temperature of -6°C?
You can store food at -6°C, but for a very short time (no more than 1-2 weeks). At this temperature, biological processes in products slow down, but do not stop completely. For long-term storage (a month or more), a temperature of -18°C or lower is required. At -6°C, meat and fish can change color and taste, and fats can oxidize.
What to do if the Atlant refrigerator hums after setting the temperature?
A slight hum is the normal operation of the compressor and the circulation of refrigerant through the system. However, if the sound becomes loud, knocking or vibration appears, check whether the refrigerator is level (adjust the legs). Also make sure that the equipment is not standing close to furniture or a wall, which can increase the resonance.
