Correct setting of the temperature regime is the foundation for the long service life of your refrigeration equipment and guarantee of food safety. Many equipment owners Atlant face a situation where the chambers become too cold or, conversely, not cool enough, which leads to spoilage of supplies. Understanding the principles of operation of the thermostat and knowing the recommended values allows you to avoid these problems without calling a specialist.
In this article we will analyze in detail what indicators are considered normal for various departments, how to set up a mechanical regulator and an electronic control panel. You will learn why you should not set the maximum power unless necessary and how seasonal changes affect the operation of the compressor. A competent approach to operation will help save energy and preserve the freshness of products.
Standard temperature standards for refrigeration compartments
The basic rule of operation is: optimum temperature in the refrigerator compartment should be in the range from +2 to +5 degrees Celsius. It is within these limits that the growth of bacteria slows down, but the food does not freeze. If you set the value lower, vegetables may lose their structure, and milk may crystallize at the walls.
For the freezer, the standard value is -18 degrees and below. Modern models Atlant with a system No Frost or static cooling are able to maintain this mode stably if the door is closed tightly. It is important to understand that a short-term increase in temperature when loading products is compensated by automation, but constant surges are harmful to the compressor.
It is worth considering the distribution of cold inside the chamber. The back wall is always colder than the door. Therefore, it is better to place perishable products, such as meat or fish, closer to the source of cold, and drinks and sauces - on door shelves or in lower drawers. Freshness zoneif it is provided for by the design, it requires special attention and often has its own microclimate.
⚠️ Attention: Do not place hot dishes in camera. This causes a sharp jump in temperature and humidity, causing the compressor to wear out, and ice to form on the walls.
How to set up a mechanical thermostat
In most classic models Atlant control is carried out using a rotary thermostat knob. It is usually located inside the refrigerator compartment at the top right or on the top panel of the case. The division scale can be digital (from 1 to 7) or marked with words (Min/Max).
It is important to remember the key feature here: the number on the scale does not mean degrees, but cooling intensity. The higher the number, the colder it will be in the chamber. Setting the knob to maximum (for example, 7) does not mean that there will be -7 degrees, it is simply a command to the compressor to work almost without stopping.
For everyday use, it is recommended to set the knob to the middle position. If you have a scale from 1 to 7, then the optimal choice would be a division of 3 or 4. This provides a balance between food safety and energy consumption. When the chamber load or room temperature changes, the position of the knob needs to be adjusted.
The adjustment is made smoothly. A sharp turn of the knob can lead to sticking of the contacts or incorrect operation of the sensor. After each change in the position of the regulator, you must wait several hours (usually 4-6) for the system to stabilize and reach a new temperature regime.
Electronic temperature control
More modern series of refrigerators Atlant are equipped with an electronic control unit with a display. Here the adjustment is more accurate, since you see the actual or target indicators in degrees. Control can be carried out by touch buttons or mechanical keys under the screen.
To enter the setting mode, you often need to hold the temperature selection button for several seconds until the numbers start flashing. After this, use the “+” and “-” buttons to set the desired value. Electronics allow you to set precise mode, for example, +3 degrees, which cannot be done mechanically.
Some models support special functions such as “Super Freeze” or “Vacation”. The Super Freeze mode forcibly lowers the temperature in the freezer to -24 degrees or lower, which is useful when loading a large amount of raw meat. The Holiday function, on the other hand, turns off the refrigerator compartment, leaving the freezer running, which saves energy while you are away.
⚠️ Attention: When using the Super Freeze function, do not leave it on for more than 24 hours unnecessarily. Long-term operation at maximum power reduces the life of the compressor.
☑️ Checking the electronics settings
Table of recommended modes for different products
Different categories of products require different storage conditions. There is no universal value for the entire chamber, so it is important to properly zone the space. Below is a table to help you navigate where and what is best stored with standard refrigerator settings.
| Product type | Recommended temperature | Optimal storage location | Shelf life (approximate) |
|---|---|---|---|
| Fresh meat/fish | 0...+2 °C | Lower shelf, freshness zone | 1-2 days |
| Dairy products | +2...+4 °C | Middle shelves, away from the wall | 3-5 days (after opening) |
| Vegetables and fruits | +4...+6 °C | Bottom boxes (containers) | 3-7 days |
| Ready meals | +2...+5 °C | Middle/upper shelves | 1-2 days |
| Frozen berries | -18 °C and below | Freezer | up to 12 months |
Please note that the shelf life is indicated for products of good quality and subject to proper operation of the equipment. Freshness zone in some models Atlant allows you to store meat for up to 3 days without freezing, maintaining its structure. This is achieved by maintaining a temperature of about 0 degrees and low humidity.
Seasonal adjustment and environmental influence
The room temperature directly affects the operation of the refrigerator. In the summer, when the apartment is hot, the compressor has to work harder to remove the heat. In winter, if the refrigerator is in an unheated hallway, the situation may be the opposite. A mechanical thermostat requires seasonal adjustment.
In summer, it is recommended to move the regulator knob towards higher values (closer to Max), but not to the maximum. This compensates for the high ambient temperature. In winter, on the contrary, if the room is cool (below +16 degrees), the power can be reduced. However, many older models have climate classlimiting the minimum room temperature.
What is a climate class?
Climate class is a parameter indicating at what ambient temperature the refrigerator can operate. For Belarus and Russia, class SN-T (from +10 to +43°C) or N-T (from +16 to +43°C) is most often suitable. Operation outside these limits leads to thickening of the oil in the compressor or overheating.
If the refrigerator is equipped with one compressor and one refrigeration circuit, changing the temperature in the freezer automatically affects the refrigerator compartment. Therefore, in winter, when the freezer is working efficiently due to the cold in the room, it may become too cold in the main chamber, and the food at the back wall will freeze. In this case, the regulator needs to be turned towards the minimum.
Diagnostics of problems with temperature conditions
Sometimes even the correct setting does not produce results. If you set the average values, but the food spoils or, conversely, freezes, the device itself may be faulty. The first sign of problems is often the formation of a “coat” (freezing of ice) on the back wall of the refrigeration chamber when defrosting is running.
Among the common reasons are:
- ❄️ Thermostat malfunction: the sensor is “stuck” and does not give the command to turn off the compressor, which is why the temperature drops below the permissible level.
- 💨 Tightness failure: a worn door seal allows warm air to pass through, causing the equipment to work without interruption, but not really cool.
- 🧊 Clogged capillary tube: the refrigerant does not circulate normally, which leads to local hypothermia or complete absence of cold.
- 🔌 Freon leak: the compressor hums constantly, but the temperature does not drop below +10 degrees.
For accurate diagnosis, it is recommended to use an external thermometer. Place a regular alcohol thermometer in a glass of water and place it on the middle shelf overnight. Check your readings in the morning. If they differ from those set on the regulator by more than 2-3 degrees, repair is required.
⚠️ Attention: If the compressor operates around the clock without stopping, and the temperature does not drop, immediately disconnect the device from the network. Long-term operation in this mode can lead to motor combustion.
Frequently asked questions and answers (FAQ)
Why does ice freeze on the back wall in the Atlant refrigerator?
This may be a sign of a malfunction of the defrosting system (heating element, timer or sensor) or simply a consequence of that the regulator is turned to maximum. Ice also appears if the door is left open or products without a lid are placed in the chamber, which actively evaporate moisture.
Which position of the thermostat knob saves the most energy?
The most economical position is the one corresponding to division 2 or 3 (on a scale up to 7). However, you need to save wisely: if the products begin to deteriorate due to high temperatures, the losses will be greater. The optimal position is the middle position.
Is it possible to place the Atlant refrigerator next to the radiator?
It is strictly not recommended. The minimum distance from heating devices should be 50 cm. The proximity of the heat source forces the compressor to work with double load, which quickly disables it and increases electricity consumption.
What to do if the temperature in the freezer is -12 instead of -18?
Check whether the drainage is clogged, whether the door closes tightly and whether there is a thick layer of ice (more than 5 mm), which works as a heat insulator. If the problem persists after defrosting, there is probably a refrigerant leak or a compressor malfunction.
