Modern refrigerators Leran are complex technical devices that require precise calibration to ensure long shelf life of products. Many users are faced with the need to change standard factory settings immediately after purchase or when the seasons change. Correct adjustment temperature conditions directly affects energy consumption and the preservation of freshness of vegetables, meat and dairy products.
Control interfaces in different series may differ significantly, which often causes difficulties for owners. In some models, all actions are performed through the touch panel on the door, in others - by mechanical controls inside the chamber. Understanding the operating principles of your unit will allow you to avoid damage to inventory and unnecessary calls to the technician.
In this article we will analyze in detail the setting algorithms for all types of control found in the equipment of this brand. You'll learn how to activate special features, such as Super Freeze, and what to do if the panel does not respond to touches. Proper operation begins with studying the instructions, but we have collected here all the key points for quick orientation.
Features of temperature control in different models
Refrigeration equipment Leran is divided into several categories depending on the type of electronic module used. The most common models are those with a display located on the outside of the top door. Here the user sees the current indicators and can quickly change them by touching the touch buttons or using mechanical keys under the screen.
In more budget or compact versions, there may be no indication at all. In such cases, adjustment occurs inside the refrigeration chamber using a rotary thermostat. Mechanical control is considered less accurate, but more reliable in conditions of unstable voltage in the network. It is important to understand which type you got in order to choose the right setting strategy.
Dual-circuit systems deserve special attention, where the temperature in the freezer and refrigerator compartments is independently regulated. This allows you to create optimal conditions for different product groups. The electronics themselves control the operation of the compressor, based on data from internal temperature sensors.
⚠️ Attention: Do not try to disassemble the control panel or change electronic modules yourself if the device is under warranty. This will result in loss of the right to free service.
If you are in doubt about your model type, please refer to the technical data sheet. The exact article number and type of control system are always indicated there. This will help you find specific instructions specifically for your case.
Setting up Leran refrigerators with an electronic display
Models with a digital display provide the user with maximum control over the climate inside the chambers. Changing settings usually requires unlocking the control panel, as manufacturers protect settings from being accidentally changed by children. The standard unlocking procedure involves holding down a certain button for 3-5 seconds.
After unlocking, the temperature value will flash on the screen. Using the arrow buttons or the +/- symbol, you can set the desired numeric value. The No Frostsystem, often used in these models, requires precise installation to avoid over-drying of food or the formation of excess condensation.
It is important to remember the range of acceptable values. For the refrigerator compartment this is usually from +2 to +8 degrees Celsius, and for the freezer - from -15 to -24. Setting extremely low temperatures unnecessarily leads to increased energy consumption and wear on the compressor.
☑️ Display setting algorithm
Some advanced models allow you to configure individual zones, for example, the “zero chamber” for meat and fish. Here, the temperature regime is maintained close to 0 degrees, which significantly extends the shelf life of perishable products without freezing.
Adjustment of a mechanical thermostat
In models without an electronic display, control is carried out using a mechanical thermostat. This device is usually located on the inner wall of the refrigerator compartment, often at the top left or mounted in the lampshade. Adjustment is made by turning the knob with digital symbols or marks.
The key point that often confuses users: the numbers on the scale of a mechanical thermostat does not indicate degrees. They indicate the intensity of the compressor. The unit corresponds to the minimum cooling (warmest temperature), and the maximum number (usually 5, 6 or 7) corresponds to the maximum cooling power.
For normal operation in summer, it is recommended to set the regulator to medium values (3-4). In winter, when the room is cool, the load can be reduced. If you set the knob to maximum, the compressor will work almost non-stop, which can lead to overheating and breakdown.
What does the scale from 1 to 7 mean?
The numbers on the mechanical regulator are not degrees Celsius, but cooling power levels. 1 - minimum cooling (warm), 7 - maximum (very cold). For everyday use, the optimal position is in the middle of the scale.
It is also worth considering that mechanical thermostats have hysteresis, that is, the spread of on and off temperatures can be quite large. Therefore, you should not expect absolute accuracy, as in electronic models with a display.
Special operating modes: Super Freeze and Eco
Modern refrigerators Leran are equipped with functions for special cases. The Super Freeze (Super Freeze) mode is designed for quick freezing of large quantities of fresh food. When activated, the compressor operates continuously, ignoring standard shutdown cycles, until you manually disable the function or the automatic timer has passed (usually 24-48 hours).
This mode cannot be used continuously, as this leads to excessive energy consumption and freezing of the evaporator. It is designed exclusively for short-term intensive cooling. After filling the freezer with new products, be sure to return the settings to normal mode.
Mode Eco (Eco), on the contrary, optimizes the operation of the unit for minimal energy consumption. In this mode, the temperature in the refrigerator compartment is maintained at the upper limit of normal (about +5...+6°C), and in the freezer - about -18°C. This is ideal for storing already frozen foods and drinks.
| Mode | Refrigerator temperature | Freezer temperature | Purpose |
|---|---|---|---|
| Standard | +4°C | -18°C | Daily storage |
| Super Freeze | Does not change | -24°C and below | Fast freezing |
| Eco | +6°C | -18°C | Energy saving |
| Vacation | +15°C | Working | Long absence |
Some models also have a “Vacation” mode, which turns off the refrigerator compartment, leaving only the freezer running. This prevents mold and odor from appearing in an empty refrigerator while you are away.
Diagnosing and troubleshooting temperature problems
If you have changed the settings, but the temperature inside does not stabilize within 24 hours, you need to carry out diagnostics. First of all, check the tightness of the sealing rubber bands. If the door does not close tightly, cold air escapes and the compressor cannot reach the set parameters.
A common cause of failures is improper loading of the chambers. If food is placed too tightly and blocks the air circulation channels, the sensors may read incorrect data. In systems No Frost free circulation of air flow is critical for uniform cooling.
⚠️ Attention: Never put hot or warm food in the refrigerator. This causes a sharp jump in temperature and causes the compressor to work hard, trying to compensate for the heat.
It is also worth checking whether the air duct supplying cold from the freezer to the refrigerator compartment is not blocked by a damper. If the damper is stuck in the closed position, the main chamber will be warm, despite the correct display settings.
FAQ: Frequently Asked Questions
Why a refrigerator makes a loud sound after changing the temperature?
This is normal. If the settings are changed abruptly, the compressor may begin to work more intensely, and the refrigerant in the tubes may begin to circulate more actively, creating noise. If the sound is not accompanied by vibration or knocking, there is no need to worry.
How often do you need to defrost a Leran refrigerator?
Models with the system No Frost do not require manual defrosting, it is enough to wash them 1-2 times a year. Models with a drip system (crying evaporator) need to be defrosted completely when the ice layer reaches 3-5 mm.
What to do if the display shows an error?
Error codes (for example, E1, E2) indicate a malfunction of the sensors or defrost system. Try unplugging the refrigerator completely for 15 minutes to reboot the system. If the error repeats, you will need to call a technician.
Is it possible to transport the refrigerator lying down?
Transporting it lying down is not recommended, since oil from the compressor may leak into the refrigerant circuit. If this happens, before turning on, let the unit stand in a vertical position for at least 4-6 hours.
What temperature is ideal for storing meat?
Fresh meat is best stored at a temperature of 0 to +2°C. In a regular refrigerator, its shelf life will be 1-2 days. For longer storage, use the super-freezing mode or vacuum pack the meat.
