Refrigerator owners Atlant often encounter the non-obvious logic of the operation of a mechanical thermostat, when there are no degrees Celsius on the scale, but only numbers from 1 up to 7. Intuitive desire turn the knob to maximum to get the “strongest cold”, which often leads to freezing of food in the main chamber or the formation of an ice coat. Understanding the operating principle of this unit is critical for the longevity of the compressor and the preservation of food freshness.
The numbers on the regulator do not indicate the temperature in degrees, but indicate the work intensity compressor. The higher the number you set, the lower the temperature inside the refrigerator compartment will be. Mechanical thermostat simply opens and closes the electrical circuit depending on the heating of the sensing element, and the scale from 1 to 7 is just a conditional division of the cooling power.
In this article we will analyze in detail which value corresponds to which temperature mode, how to correctly configure the device depending on the time of year and what to do if the refrigerator has stopped freezing even at maximum values. The optimal mode for everyday use in the summer is most often is the position of the regulator between 3 and 4. We will analyze the nuances that will help you avoid typical operating mistakes.
The principle of operation of a mechanical thermostat
The mechanical thermostat installed in refrigerators Atlantis a simple but reliable electromechanical device. Inside the case there is capillary tubefilled with gas or liquid, which reacts to temperature changes. When the air in the chamber heats up, the substance expands, the pressure rises, and the contacts close, starting the compressor.
Turning the regulator knob changes the tension of the spring inside the mechanism. At division "1" the spring is stretched minimally, so a very small change in pressure in the capillary is required to close the contacts. This means that the compressor will turn on rarely and work for a short time, maintaining a high temperature inside the chamber. Attention: Never try to forcibly turn the regulator knob if it rests against the limiter. The mechanical drive is fragile, and a breakdown of the plastic rod will require replacing the entire thermostat. high temperature inside the camera.
⚠️ Attention: Never try to forcibly (force) turn the regulator knob if it rests against the limiter. The mechanical drive is fragile, and breaking the plastic rod will require replacing the entire thermostat.
At the opposite end of the scale, in the area of numbers 6 and 7, the spring tension is maximum. The compressor will run almost continuously, trying to reach temperatures that can be extremely cold for a domestic refrigerator. Understanding this physics of the process helps to avoid situations when motor-compressor works for wear and tear unnecessarily.
Deciphering the values of the scale from 1 to 7
Each number on the refrigerator control panel Atlant corresponds to a specific temperature range and operating mode. It is important for the user to know what is hidden behind each division in order to correctly respond to changes in environmental conditions or the amount of loaded products.
Let's consider a detailed explanation of the values:
- ❄️ 1 (Minimum): The compressor operates in a gentle mode. The temperature in the main chamber can reach +8...+10°C. This mode is suitable for storing drinks or when the refrigerator is almost empty.
- 🌡️ 2-3 (Average minimum): Optimal range for winter or cool kitchens. The temperature is kept within +5...+7°C.
- ✅ 4 (Normal): Standard factory position. Provides a temperature of about +4...+5°C, which is ideal for most products (meat, dairy, ready-made dishes).
- 🧊 5-6 (Maximum): Intensive cooling. Used in the summer, when the chamber is fully loaded with food or if you need to quickly cool a large number of warm (but not hot!) items.
- ⛔ 7 (Stop/Freeze): Forced continuous operation of the compressor. The temperature may drop below 0°C in the main chamber. Use only for a short time!
It is important to note that the actual temperature inside the chamber depends not only on the position of the handle, but also on room temperature. If the kitchen is hot, then even position "4" can give a higher temperature than in winter with position "3".
The influence of seasonality on refrigerator settings
One of the most common mistakes is ignoring the seasonal factor when setting Atlanta. In summer and winter, the thermal load on the insulation of the refrigerator is radically different, which requires adjustment of the position of the thermostat to save electricity and equipment life.
In the summer, when the air temperature in the apartment can reach +25...+30°C, heat flow through the walls of the refrigerator increases. To maintain the set temperature, the compressor has to work harder. At this time of year, it is recommended to set the regulator to 4 or 5. If you leave position "2", the compressor may not be able to cope with heat inflows, and the products will begin to deteriorate.
In winter, the situation changes. If the refrigerator is in a heated room, position 2 or 3is sufficient. However, if the equipment is located on an unheated loggia or in a corridor where the temperature drops below +10°C, problems may arise. A mechanical thermostat may simply not “understand” that the motor needs to be turned on, since it is already cold in the chamber. In such cases, installation of winter set for a refrigerator is sometimes required, although modern models Atlant often have an extended climate class.
There is a common myth that in winter you need to set the maximum cold. This is a mistake. On the contrary, in winter the temperature difference between the chamber and the room is smaller (or negative if the refrigerator is on the balcony), and the load on the unit is reduced.
Super Freeze mode and position 7
The position of the regulator at number 7 (or the red zone) in refrigerators Atlant is often called "Super Freeze" or "Max Cool" mode. In this position, the thermostat contacts close directly, bypassing the temperature sensor, and the compressor operates continuously without turning off.
This mode is intended for:
- 🍖 Quick freezing of large quantities of fresh food in the freezer (to preserve the structure fiber).
- 📉 Rapidly lowering the temperature after defrosting or loading a large volume of warm food.
- 🔋 Creating a cold reserve before a long power outage (for example, before a trip).
⚠️ Attention: Never leave the refrigerator in position "7" on a permanent basis! This will lead to freezing of the evaporator, breakdown of the compressor due to overheating and significant waste of electricity.
You can use this mode for no more than 6-12 hours. After the products are frozen, the regulator required needs to be returned to its working position (3-4). Ignoring this rule is one of the main reasons for equipment failure Atlant in the first years of operation.
What happens if you forget to switch from 7?
If you leave the maximum power mode for several days, the evaporator will become covered with a thick layer of ice, which will block air circulation. The cold will stop flowing into the chamber, although the compressor will hum. In addition, the motor can burn out from overload or constant operation without rest.
Step-by-step instructions for proper setup
To ensure that your refrigerator Atlant worked efficiently and economically, it is necessary to carry out initial setup after purchase or defrosting. You should not immediately load the chamber with food - let the equipment go into mode.
Follow this algorithm of actions:
- Set the temperature regulator to the middle position (number 3 or 4).
- Plug in the refrigerator and leave it empty for 2-3 hours.
- Check the temperature inside using a separate thermometer (put it in a glass of water on the middle shelf).
- If the temperature is above +5°C, turn the knob one notch upward (toward number 5). If below 0°C, reduce the value.
☑️ Initial setup checklist
Repeat measurements and adjustments throughout the day. Remember that thermoinertia is large: a change in the position of the handle will not affect the temperature inside the chamber immediately, but after 1-2 hours of operation of the compressor.
Table of correspondence of modes and temperatures
For ease of perception of information, we will summarize the main parameters into a single table. Please note that the indicated temperatures are averaged and may vary depending on the specific model Atlant and operating conditions.
| Knob position | Operating mode | Approximate t° in camera | Recommendation for use |
|---|---|---|---|
| 1 | Minimum | +8...+10°C | Short-term storage of drinks, almost empty refrigerator. |
| 3 | Medium (Winter) | +5...+7°C | Standard mode for winter period or cool kitchen. |
| 4 | Normal (Standard) | +3...+5°C | Daily use, optimal for most products. |
| 6 | Maximum | 0...+2°C | Hot summer, full load of products, high room temperature. |
| 7 | Turbo / Stop | < 0°C | Only for quick freezing (no more than 12 hours). |
Using this table will help you quickly navigate if you notice that food in the refrigerator begins to thaw or, conversely, freeze.
Typical problems and their solution
Even with proper configuration, users may encounter problems. Owners often complain that the refrigerator Atlant"doesn't freeze", although the regulator is turned up to the maximum. In this case, the problem is most likely not in the settings, but in system malfunction: a freon leak, a compressor malfunction or a clogged capillary tube.
The other extreme is that the refrigerator “freezes.” If a “coat” of ice forms on the back wall of the main chamber even in position 2-3, this may indicate:
- ❄️ Thermostat malfunction: It is "stuck" in a closed state and does not allow the compressor to turn off.
- 🚪 Tightness failure: Worn door seal allows warm, moist air to pass through, which condenses and freezes.
- 🌡️ Knob position: The user accidentally switched the regulator to 6 or 7.
⚠️ Attention: If you set the regulator to minimum (1), and The refrigerator compressor does not turn off for hours - this is a sure sign of a broken thermostat or loss of freon. A call to the technician is required.
Frequently asked questions (FAQ)
Why does the Atlant refrigerator not turn off at number 7?
Because position 7 (or red zone) on mechanical thermostats Atlant means continuous operation mode. In this position, the thermostat forcibly closes the circuit, ignoring the temperature inside the chamber. This is made for quick freezing. If you leave it like this for a long time, the compressor will burn out.
Which position of the regulator saves the most electricity?
The lowest electricity consumption is achieved at the division 1 or 2. However, at these values, the temperature in the chamber may not be low enough to safely store perishable food. The optimal balance between economy and storage quality is position 3 or 4.
Is it possible to use the Atlant refrigerator on the balcony in winter?
Most models Atlant have climate class SN-N (from +10°C to +10°C to +32°C). If the temperature on the balcony drops below +10°C, the oil in the compressor thickens and it may not start or quickly fail. In addition, the thermostat may not turn on the motor, since the chamber will be warmer than outside. Operation at temperatures below +5°C is not recommended without a special winter kit.
What to do if the regulator knob rotates endlessly?
If the thermostat knob rotates in a circle without clicks or stops, this is a sign of mechanical failure of the regulator itself. In this state, it cannot break the electrical circuit. It is necessary to replace the thermostat with a new one, since this unit usually cannot be repaired.
