Correct setting of the temperature regime is the key to long-term storage of products and proper operation of your refrigeration equipment. Many equipment owners Atlant face the question of how exactly to regulate the cold in order to avoid food spoilage or unnecessary energy consumption. Unlike some modern models with electronic control, classic refrigerators of this brand are often equipped with mechanical regulators, which requires an understanding of the principles of their operation.
The optimal temperature inside the chambers depends on many factors: the number of loaded products, the temperature in the room and the frequency of opening the doors. Incorrectly set values can lead to the formation of ice in the freezer or, conversely, to insufficient cooling in the main compartment. Understanding how thermostat works in your model will help you avoid typical mistakes during operation.
In this article we will examine in detail the setup process for various modifications, including No Frost and drip-type systems. You will learn what values are considered normal for different compartments, and how to diagnose problems if the refrigerator no longer maintains the set mode. Proper adjustment will extend the life of the compressor and keep your supplies fresh.
The principle of operation of the Atlant thermostat
The basis for cold control in most models Atlant is a mechanical thermostat. This device reacts to changes in temperature inside the refrigerator compartment and sends a signal to the compressor to turn on or off. The adjustment is carried out by turning the handle, which changes the tension force of the spring inside the sensor, thereby setting the response threshold.
It is important to understand that the number on the regulator scale does not indicate degrees Celsius. This is a conditional index of cooling power. The higher the value, the the compressor works more intensely and the lower the temperature inside the chamber drops. If you turn the knob to the maximum, the refrigerator will work almost without stopping, which can lead to freezing of food.
⚠️ Attention: A sharp change in the position of the regulator will not lead to an instant change in temperature. The compressor takes from 30 to 60 minutes to stabilize the climate inside the chambers after your adjustment.
Electronic control systems found in more expensive models operate on a different principle. Here the microprocessor receives data from several sensors and accurately controls the operation of the units. However, even in such systems, the basic principle remains the same: you set the desired parameter, and the automation supports it.
Why is the scale not in degrees?
Mechanical thermostats are calibrated at the factory for a specific refrigerant and chamber volume. The 1 to 7 (or Min-Max) scale is simply a range of spring tension, not an accurate thermometer.
Optimal temperature values for different chambers
In order to ensure safe food storage, certain standards must be adhered to. In the refrigerator compartment, the ideal range is considered to be from +2 to +4 degrees Celsius. Under such conditions, bacteria multiply more slowly, and food does not freeze at the back wall. In the freezer compartment, the temperature should be no higher -18 degrees, which allows you to store meat and fish for up to a year.
If you store a large amount of perishable food, such as fresh meat or dairy products, it is better to shift the settings closer to the lower end of the range. For vegetables and fruits, on the contrary, too low a temperature can be destructive, causing loss of moisture and tissue structure. Balancing the settings depends on what exactly you stock the shelves with.
Below is a table of recommended settings for various types of products and storage areas:
| Product type | Recommended temperature | Shelf life (approximate) |
|---|---|---|
| Fresh meat/fish | 0...+2 °C | 1-2 days |
| Dairy products | +2...+4 °C | 3-5 days |
| Vegetables and fruits | +4...+6 °C | up to 7 days |
| Frozen semi-finished products | -18...-24 °C | up to 12 months |
It is worth considering that the temperature on different shelves may vary. It is usually warmer on the top shelves, and colder near the back wall, where it is located evaporator. Distribute food accordingly to avoid spoilage or freezing.
Setting the mechanical regulator (single-compressor models)
In classic two-chamber refrigerators Atlant with one compressor, the temperature regulator is located inside the refrigeration chamber, usually in upper right corner. The scale can contain numbers from 1 to 7 or designations Min and Max. For initial settings, it is recommended to set the knob to the middle position, usually the number 3 or 4.
If you notice that the food in the refrigerator begins to freeze at the back wall, you need to reduce the cooling power. To do this, turn the handle counterclockwise one notch. If, on the contrary, the products quickly deteriorate or the chamber is too warm, add power by turning the knob towards higher values.
☑️ Algorithm for setting the mechanics
Remember that in models with one compressor, cold is produced in the freezer and then distributed to the refrigerator. Therefore, by adjusting the thermostat, you primarily control the temperature in the upper compartment, and the freezer works in conjunction with it. If the freezer has stopped freezing, and the refrigerator is warm, the problem may not be in the settings, but in a freon leak or a compressor malfunction.
Temperature control in No Frost models
Refrigerators Atlant with a system No Frost are often equipped with more advanced control panels, which can be located both inside the chamber and on the external door. Here the setup process looks different: you see specific numbers indicating degrees, or letter codes for modes. This greatly simplifies the user’s life, eliminating the need to guess what “five” on the scale means.
To enter the setup mode, you usually need to long press the button with the image of a thermometer or a snowflake. After activating the mode, the numbers begin to flash, allowing you to change the value using the + and -buttons. In such models, it is important not to set the temperature in the refrigerator compartment below +3 degrees, as this can lead to excessive condensation and freezing of the air ducts.
⚠️ Attention: In No Frost systems, frequent opening of doors in hot weather can cause a short-term increase in temperature. Do not rush to immediately turn the regulator to maximum - give the system 2-3 hours to restore the mode.
The “Super Freeze” function deserves special attention (often indicated by a snowflake or button Super Freeze). When activated, the compressor runs continuously, ignoring the thermostat readings, in order to quickly freeze a fresh load. Do not leave this mode on for more than 24-48 hoursas this leads to overload of the motor and a significant increase in electricity consumption.
Adjustment of two-compressor systems
In two-compressor models Atlant each chamber is responsible for a separate unit and, accordingly, a separate regulator. This gives a huge advantage: you can independently adjust the temperature in the freezer and refrigerator. The regulators in such models are also located inside the chambers, each above its own compartment.
If you rarely use the freezer, you can set the minimum cooling power there (number 1 or Min), saving energy. At the same time, you can keep the standard +4 degrees in the refrigerator compartment. This independence is especially convenient when defrosting one of the circuits or when loading a large volume of food into only one of the chambers.
When setting up a two-compressor unit, follow the rule: first set up the refrigeration chamber, wait for stabilization, and then proceed to the freezer. This will help you understand how each circuit works separately. If one of the compressors is constantly running and the second is turned off, check whether the quick freezing function is turned on or whether the condenser is clogged with dust.
Frequent problems and their solution through setting
Sometimes users are faced with a situation where seemingly correct settings do not produce results. For example, the refrigerator is too cold, even on low. This may indicate sticking thermostat contacts or loss of sensor sensitivity. In such cases, simply twisting the knob may not help, and diagnostics will be required.
Another common problem is the formation of a “fur coat” or ice crust on food. If you have a drip system, this is often a sign that the temperature is set too low for the moisture to evaporate from the evaporator patch. Try increasing the value on the regulator by one notch and checking the condition of the drainage hole.
- 🧊 Ice on the back wall: Reduce the cooling power or check the door seal.
- 🥩 Food is spoiling: Add power, check if the cold air flow is blocking the food.
- 🔊 Noisy operation: Make sure that the refrigerator is level and the compressor does not vibrate against the body.
If after all the manipulations the refrigerator continues to work incorrectly, it may not be the settings. Wear of the seal, loss of system tightness or malfunction of the electronics require the intervention of a specialist. You should not ignore the signals from the equipment, hoping that “it will go away on its own.”
The influence of external factors on the temperature regime
Do not forget that the refrigerator Atlant does not work in a vacuum. Room temperature, direct sunlight and proximity to heating devices directly affect cooling efficiency. If the kitchen is hot, the compressor has to work harder to maintain the set parameters.
In winter, if the refrigerator is located in an unheated country house or balcony, problems may arise with starting. The mineral oil in the compressor thickens, and the unit may not start or operate intermittently. In such conditions, it is recommended to use the refrigerator only in a warm room or purchase models with climate class SN-Tadapted for a wide range of temperatures.
⚠️ Attention: Installing the refrigerator closer than 10 cm to a wall or in a niche without ventilation leads to overheating of the condenser. This makes the thermostat “think” that the chamber is warm and forces the compressor to work without interruption.
The amount of food also affects the load. An empty refrigerator cools down faster, but also heats up faster when the door is opened. A full refrigerator holds the cold better due to the heat capacity of the food, but takes longer to initially cool down. Try not to overfill the chamber, leaving space for air circulation.
FAQ: Frequently Asked Questions
What should you do if the control knob turns endlessly?
If you turn the knob and there is no click and the range is not limited, the internal thermostat mechanism may be broken. In normal condition, there should be stops at the Min and Max positions. The thermostat needs to be replaced.
Is it possible to set the temperature in degrees on the mechanics?
No, the mechanical scale is conventional. To find out the exact temperature, use an external thermometer, placing it in a glass of water on the middle shelf for 6-8 hours.
Why does the temperature not return for a long time after defrosting?
After defrosting and turning on, the refrigerator takes from 4 to 12 hours to return to operating mode. At this time, do not load a lot of food and do not open the doors often.
How to understand that the thermostat is faulty?
Main symptoms: the compressor does not turn on at all (or works without stopping), no click when turning the handle, incorrect temperature at any setting.
