Correct temperature settings are the foundation on which not only the freshness of your products rests, but also the durability of the household appliance itself. Refrigeration equipment of the brand Leran has proven itself to be reliable equipment, however, many users encounter difficulties during initial operation or after defrosting, not knowing how to set the correct values. Understanding the principles of operation of the thermostat will help you avoid premature spoilage of food and reduce the energy consumption of the device.
Unlike complex electronic control systems, mechanical models require careful attention to the details of the settings. Temperature conditions directly affects the freezing speed and the ability of the compressor to cope with the load. If you have just purchased a unit or noticed that food has begun to freeze or, conversely, quickly deteriorate, you need to audit the current settings. In this article, we will analyze in detail all aspects of adjustment so that you can be sure that your equipment is working properly.
It is worth noting that the environment also plays a role in the efficiency of the refrigerator. In summer, when the room is hot, or in winter, if the equipment is in an unheated area, the settings may require correction. Microclimate stability inside the cameras depends on how correctly you took into account external factors. Let's move on to specific steps and recommendations that will help you set up your Leran perfectly.
The principle of operation of the thermostat and the scale of values
In most refrigerator models Leran a mechanical thermostat is used, which looks like a rotary switch with a digital scale. It is important to understand that the numbers on this regulator do not directly indicate degrees Celsius. They indicate cooling intensity: the higher the number, the colder it will be inside the chamber. The scale usually ranges from 0 or 1 to 7, where the extreme values correspond to the minimum and maximum power of the compressor.
Users often make the mistake of believing that setting the maximum value (for example, 7) will instantly cool food to the desired temperature. In fact, this causes it to compressor work almost non-stop, which can cause it to overheat and increase your electricity bill. The optimal factory setting for most situations is the position of the regulator in the middle of the scale, usually numbers 3 or 4. It is from this value that it is recommended to start operation.
⚠️ Attention: Never set the regulator immediately to maximum after a long period of inactivity of the equipment. A sudden start at full power can stress the refrigerant and compressor. Let the system enter the mode gradually.
If you notice that it is too cold in the main chamber and the products at the back wall are freezing, you should turn the knob towards lower values. Conversely, if the milk quickly sours and the meat loses color, the cooling power must be added. Temperature balance This is not a static value, but a dynamic process depending on the load of shelves and the frequency of door openings.
Optimal temperature conditions for different products
For Preserving the taste and safety of food requires maintaining strictly defined conditions. In the main refrigeration chamber, the ideal range is considered to be from +2 to +5 degrees Celsius. At these rates, bacteria multiply slowly, but vegetables do not freeze. In the freezer compartment, the temperature should drop below -18 degrees, which ensures deep freezing and long-term storage of supplies.
Different areas inside the refrigerator Leran may have different temperatures due to air circulation. The upper shelves are usually warmer, while the lower ones are colder. Therefore, it is important to distribute food correctly:
- 🥛 Dairy products and prepared meals are best stored on the middle shelves, where the temperature is most stable.
- 🥩 Raw meat and fish should be placed on the bottom shelf, closer to the freshness zone, to prevent cross-contamination and ensure maximum cold.
- 🥦 Vegetables and fruits require high humidity, so their place is in special drawers below, where the risk of freezing is minimal.
- 🥚 It is convenient to store eggs and sauces on door shelves, although there the temperature fluctuates more often due to the opening of the door.
Following these rules will significantly extend the shelf life of products. For example, meat at a temperature of +4 degrees will remain fresh for up to two days, while at +8 degrees this period will be halved. Control of storage conditions This is your main task after the initial setup of the equipment.
Step-by-step instructions for setting up a mechanical regulator
The process of adjusting the temperature in refrigerators Leran is quite simple, but requires a sequence of actions to achieve an accurate result. First you need to clear the space around the regulator so that nothing interferes with the rotation of the knob. Then you should determine the current position of the switch and understand in which direction it needs to be turned.
For the convenience of users, we have prepared a checklist that will help you not to miss important settings details:
☑️ Setting the temperature
After you have changed the position of the knob, do not wait instant results. The refrigerator needs time to rebuild its operation cooling cycle. Typically, temperature stabilization at all points in the chamber takes from 6 to 12 hours, and in some cases up to a day. Only after this time can one draw conclusions about the effectiveness of the adjustment and the need for further adjustments.
If, after changing the mode, you hear that the motor-compressor is working too loudly or, conversely, turns on extremely rarely, it is worth checking the tightness of the door seal. Sometimes the problem lies not in the settings, but in depressurization of the circuit, which negates all adjustment efforts.
Features of setting up two-chamber and three-chamber models
Owners of refrigerators Leran with a system No Frost or combined cooling should take into account that in Such models often use one common thermostat for the refrigerator compartment, and the freezer is controlled automatically or by dampers. This means that changing the settings of the main regulator will affect the temperature throughout the entire volume of the device.
In three-chamber models, where there is a “zero temperature” zone or a separate compartment for vegetables, additional dampers may be present. Their position regulates the flow of cold air. If you notice that the temperature in the freshness area is not as expected, check that the ventilation grille is not blocked by food. Air circulation Critical for even distribution of cold.
| Knob position | Operating mode | Impact on products | Recommended time of year |
|---|---|---|---|
| 1 (Min) | Minimum cooling | Risk of spoilage of perishable products | Winter (in an unheated room) |
| 3-4 (Average) | Normal mode | Optimal storage of most products | All-season (standard) |
| 6-7 (Max) | Intensive cooling | Risk of freezing vegetables and herbs | Summer or full load |
Using the table above will help you navigate the choice of mode depending on the season and load. Remember that in winter, if the refrigerator is in a cool room, setting the minimum value may result in the compressor not starting at all, since the thermostat will “think” that it is already cold enough inside.
The influence of the external environment and load on the operation of the refrigerator
Temperature in the room where it is installed Leran, has a direct impact on the efficiency of its work. If the kitchen is hot (above +30 degrees), the refrigerator will have to work harder to maintain the set parameters. In such cases, it is allowed to shift the regulator by one division towards increasing power, but nothing more.
The load of the chambers also plays a role. An empty refrigerator cools down faster, but it also loses cold faster when the door is opened. A completely clogged unit requires more time for initial cooling, but holds the temperature better. Thermal capacity of products helps stabilize the microclimate, so you should not keep the refrigerator empty.
