Correctly setting the temperature in the refrigerator is not easy a matter of comfort, but also a guarantee of the safety of your products, as well as the durability of the unit itself. Equipment owners Atlant often face a dilemma: set the minimum values to save energy or maximize cooling, risking freezing vegetables. Understanding the operating principles of thermostat will help you avoid these extremes.
Many users mistakenly believe that the number on the regulator directly corresponds to degrees Celsius, but this is not the case. In fact, a scale from 1 to 7 (or up to 5 in some models) indicates the intensity of the compressor. The higher the value, the more intense cooling and lower the temperature inside the chambers. For most situations, the “golden mean” is a position that provides a stable climate without overloading the motor.
In this article we will analyze in detail how to find the ideal position of the thermostat knob for your specific case, taking into account seasonality, product load and design features of the model. You will learn why the settings may differ in winter from the summer, and how to extend the life of the refrigeration unit through proper operation.
The principle of operation of the thermostat and decoding of the scale
To correctly configure Atlant refrigerator, You must first understand the logic of the control device. A thermostat (or thermostat) is a device that automatically turns the compressor on and off depending on the temperature inside the chamber. When you turn the knob to a higher number, you set a lower target temperature, causing the compressor to work longer and more often.
The standard scale on most models Atlant looks like this:
- 🔹 Digit 1 (Min): Minimum cooling. The compressor turns on rarely, the temperature in the main chamber can reach +8...+10°C. Suitable for vacation mode or storing products that do not require extreme cold.
- 🔹 Numbers 2-3: Economy mode. The temperature stays around +5...+7°C. This is optimal for partial load or in winter, when the apartment is not hot.
- 🔹 Numbers 4-5: Standard operating mode. Provides a temperature of +2...+5°C, which is ideal for most products. The compressor operates in the normal cycle.
- 🔹 Numbers 6-7 (Max): Maximum cooling (turbo mode). Temperatures can drop to 0°C or below. Used for quick freezing or when fully loaded with warm products.
It is important to note that in two-chamber models with one compressor, the regulator usually controls the temperature in the refrigerator compartment, and the freezer is cooled according to the residual principle. Therefore, by turning the knob to the maximum, you risk freezing vegetables in the main chamber until you reach the required -18°C in the freezer.
⚠️ Attention: Do not leave the regulator constantly at the maximum value (6 or 7) in normal operation. This leads to continuous operation of the compressor, the formation of a snow coat on the rear wall and rapid wear of the motor.
Optimal settings for different seasons
External ambient temperature has a direct effect on heat transfer. In summer, the apartment is hot, and the refrigerator requires more effort to remove heat from the chambers. In winter, when the room is cool, the load on unit reduces. Ignoring this factor is a common cause of breakdowns.
In the summer, when the air temperature in the kitchen exceeds +25°C, it is recommended to set the regulator to values 3 or 4. This will maintain stable cold without extreme loads. If you set the value lower (1-2), the compressor may simply not cope with the heat, and the food will begin to spoil.
In winter, the situation changes. If you do not use the "Vacation" function and the refrigerator operates in a heated room, the optimal value will be 2 or 3. If the setting is too high (5-7), excessive freezing of the evaporator may occur in winter, since the temperature difference between the street and the internal chamber is minimal.
| Season | Indoor temperature | Recommended figure | Purpose of setting |
|---|---|---|---|
| Summer | +25°C and above | 3 - 4 | Heat compensation |
| Off-season | +18...+22°C | 3 - 4 | Standard mode |
| Winter | up to +18°C | 2 - 3 | Saving and protection |
| Vacation | Any | 1 (Min) | Keeping it fresh |
There is a common misconception that in winter the refrigerator needs to be turned off or set to minimum if it is on an unheated veranda. For equipment Atlant operation at temperatures below +10°C (for single-compressor models) can be dangerous: the oil in the compressor thickens, and starting the engine can lead to its wedge.
Settings for single-chamber and double-chamber models
The design of the refrigerator dictates its own setting rules. In single-chamber models Atlant (for example, the MXM-1700 series), the freezer compartment (if there is one) is located inside the main volume and is often separated by a plastic door or flap. Here the regulator affects the overall temperature.
Single-chamber units without a “crying” wall (drip system) are characterized by the formation of ice on the rear panel. In such models, it is not recommended to set the regulator above number 3, otherwise you will have to carry out too often defrosting. The optimal mode is 2.5 (between divisions), which allows for a balance of cold and the absence of ice.
In two-chamber models with one compressor (the most common type), cold is pumped into the freezer compartment, and enters the refrigerator through the channels. The adjustment is based on the temperature in the refrigerator compartment. If you set it to 7, the freezer will be -24°C, and the refrigerator will be about 0°C, which will lead to freezing of milk and vegetables.
- 🔸 Models with No Frost: Here the system itself distributes the cold, but the principle of the regulator remains the same. They are characterized by higher numbers (4-5) as a standard, since the system removes moisture more effectively.
- 🔸 Models with a drip system: Require more careful attention to settings to prevent condensation from turning into an ice crust.
⚠️ Attention: In models with electronic control (display on the door), the principle is the same: decreasing the digital temperature value (for example, from +5 to +2) is equivalent to turning the mechanical knob towards larger numbers. Do not confuse the degree scale and the power scale!
Why is there ice in the freezer, but warm in the refrigerator?
This is a classic sign of poor air circulation or too high a thermostat setting. Try lowering the value on the regulator by 1 notch and check if the air ducts are clogged with food.
The influence of food loading on the operation of the thermostat
The quantity and temperature of food is a critical factor. An empty refrigerator and a completely filled one require different approaches to setting thermostat. The air cools quickly, but does not maintain temperature well. Products (especially liquids) take a long time to cool, but are excellent cold accumulators.
If you have just returned from the supermarket and loaded Atlant refrigerator packages with room temperature foods, the internal temperature has risen sharply. At this moment, the thermostat, set to “three”, will consider that there is enough cold and will not turn on the compressor for a long time. Products may begin to deteriorate.
In such cases it is necessary:
- Temporarily set the regulator to the maximum value (6 or 7).
- Allow the unit to operate in high mode for 2-3 hours.
- After To stabilize the temperature, return the handle to the operating position (3-4).
On the contrary, if the refrigerator is almost empty, it makes no sense to set the cooling power to high. The air will quickly cool down, the compressor will turn off, but due to the small volume of “cold accumulators” (products), the temperature will begin to rise quickly, and the motor will turn on too often. This is harmful to start relay.
☑️ Correct loading of the refrigerator
Specific settings of the freezer compartment
Setting the freezer compartment deserves special attention. In most household models Atlant there is no separate regulator for the freezer - it works in conjunction with the main compartment. However, some advanced models may have a separate switch or damper.
The optimal temperature for long-term storage of meat, fish and semi-finished products is -18°C. This value corresponds to the position of the regulator, at which the refrigerator compartment is about +4°C. If you set the regulator to minimum (1), the temperature in the freezer can rise to -6...-8°C, which will reduce the shelf life of food to several weeks.
For quick freezing of fresh berries, meat or mushrooms, many models Atlant are equipped with a “Super Freeze” mode. In mechanical models, this is often achieved by moving the control to the extreme right position or by turning on a separate button. In this mode, the compressor operates continuously, ignoring the thermostat readings.
It is important not to forget to turn off the super freezing mode after 24 hours (or automatically, if the model allows), otherwise you risk burning the compressor and getting ice freezing several centimeters thick, which will worsen heat transfer.
Typical errors and troubleshooting
Even knowing what number the regulator should be on, users often make mistakes that lead to perceived breakdowns. The most common of them is the expectation of instant results. After turning the knob thermostat the temperature in the chamber stabilizes only after 4-6 hours.
Another mistake - the placement of the thermometer is incorrect. To check the actual temperature, place a regular household thermometer in a glass of water on the middle shelf. Measuring "on weight" in the air will give incorrect data due to the on-off cycles of the compressor.
List of common problems associated with the setting:
- ❄️ Increasing "fur coat" on the back wall: The regulator is too high (5-7), or the defrost sensor is faulty.
- 🥛 The food in the refrigerator freezes: The regulator is turned to the maximum, or the cold air supply damper is stuck in the open position.
- 🌡️ The chamber is warm, the compressor is silent: The regulator is at a minimum (1) in a hot room, or there is a freon leak, or a breakdown of the thermostat.
⚠️ Attention: If you set the regulator to 4, and the refrigerator does not turn on for more than 2 hours (while the chamber is warm), or works without a break for days, the problem is not in the settings. Most likely, the automation has failed or there has been a refrigerant leak. A call from a specialist is required.
Frequently asked questions (FAQ)
What should I do if the control knob spins endlessly?
In some older models Atlant or if the limiter is broken The handle can rotate in a circle without clicking. This means that the thermostat mechanism is damaged or knocked down. In this situation, the refrigerator will most likely either not turn on or will work constantly. It is necessary to fix the handle at 3 (approximately 12 o'clock) with glue or a marker and observe the temperature. If the mode does not stabilize, the thermostat needs to be replaced.
Is it possible to keep the refrigerator on number 7 all the time?
It is strictly not recommended. Number 7 (Max) is intended for short-term use (fast freezing mode). Constant operation at maximum leads to the fact that the compressor does not turn off, consuming maximum electricity. This causes overheating of the motor, deformation of the seals and freezing of the condensate drainage channels, which can lead to a flood in the kitchen.
Why does the instruction say one thing, but on the regulator itself there are different numbers?
The model range Atlant is very wide. There are scales from 0 to 7, from 1 to 5, or even from Min to Max. The logic is the same everywhere: higher value = stronger cold. If your scale is 1-5, then the “golden mean” will be 3. If it is 1-7, then 3-4. Always focus on the middle of the scale of your specific device.
How to understand that the thermostat is faulty?
Main signs of a malfunction: the refrigerator does not turn on at all (even when the knob is turned to maximum), or it turns on and works without stopping, without gaining temperature. Another sign may be the absence of a characteristic click when turning the knob from the “off” position to the “1” position. In such cases, diagnostics with a multimeter is required.
Does the position of the refrigerator against the wall affect the settings?
Yes, indirectly. If the refrigerator is placed close to a wall or furniture, the air circulation around the condenser (the grille at the back) is disrupted. The unit gives off heat less well, and to maintain the same temperature inside it has to work more intensely. In this case, even on a standard “three” it can work as if on a “five”. Be sure to leave a gap of at least 5-7 cm from the back wall to the furniture.
