Modern refrigeration units of the brand Liebherr are famous for their accuracy and energy efficiency. However, many owners encounter difficulties during the initial setup or changing the operating parameters of the equipment. An incorrectly set mode can lead to spoilage of food or the formation of excessive ice.
In this article we will analyze in detail the algorithms of actions for various types of control. You will learn how to adjust the cooling in the chambers, use the fast freezing functions and avoid common operating mistakes. Proper setup is the key to a long service life of the compressor.
Principles of operation of the SmartSteel and SmartDevice control system
Before starting manipulations, it is important to understand the logic of the interface of your model. Devices Liebherr are equipped with touch panels SmartSteel (metal surface) or more modern systems with support SmartDeviceBoxThe main difference lies in the method of activating the modes, but the logic of the temperature zones is the same.
The central processor reads the temperature sensors and adjusts the operation of the compressor. When you change settings, you are instructing the system to change the target value, rather than directly controlling the motor power. This ensures the stability of the climate inside the chambers after the transition process is completed.
It is important to consider that the reaction to your actions does not occur instantly. The system should stabilize air flows. Sharp jumps in values can mislead electronics, so make all changes smoothly and consistently.
- 🧊 Accuracy: The adjustment step is usually 1 degree Celsius, which allows you to choose the ideal mode.
- 📱 Remote access: Models with Wi-Fi allow you to change settings via the application SmartDevice.
- 🔋 Savings: Correct settings reduce energy consumption by up to 15%.
Temperature adjustment in the refrigerator compartment
The optimal value for storing most products in the main chamber is considered to be from +3 to +5 degrees Celsius. It is at these rates that bacteria multiply slowest, and food does not freeze. To set these parameters, you must activate the setup mode.
Press the button Refrigerator or the icon with the image of a snowflake (depending on the series). The display will start flashing the current value. Use the + and - buttons to change the indicator. After selecting the desired number, wait a few seconds until the indicator stops blinking - this is a signal about saving.
If you have a model with a mechanical regulator inside the chamber, turn the wheel counterclockwise to lower the temperature (increasing cold) and clockwise to increase it. The numbers on the mechanics do not mean degrees, but power: the higher the number, the colder.
⚠️ Attention: Do not set the minimum possible temperature (+2°C) unless absolutely necessary. This can lead to freezing of vegetables on the bottom shelf and increase the load on the compressor.
Freezer Settings and SuperFrost Mode
The freezer requires lower values, usually between -18 and -24 degrees. The SuperFrostfunction is intended for quick freezing of fresh food or creating a supply of ice. It temporarily lowers the temperature to extreme values, accelerating the crystallization of moisture inside the products.
To activate the mode, press the corresponding button on the panel. The indicator will light up and the system will begin to work intensively. In most modern models Liebherr this mode turns off automatically after 65 hours. Forced shutdown is performed by pressing the button again.
Continuous operation in super freezing mode is not recommended. This leads to accelerated wear of parts and excessive consumption of electricity. Use the function only when loading a large volume of fresh food.
☑️ Checking the operation of the freezer
Pay attention to the distribution of cold. In the chambers NoFrost air circulates forcibly, so the temperature may be slightly higher at the door. Try not to block the ventilation holes with food, this will disrupt heat transfer.
Using the SuperCool function for quick cooling
An analogue of quick freezing for the refrigerator compartment is the SuperCoolmode. It is useful when you have brought a lot of food at room temperature or are preparing for the arrival of guests. The system operates at maximum power, ignoring standard rest cycles.
Activation occurs in the same way as other functions: by pressing the button with the corresponding icon. The operating time is usually limited to 6-12 hours, after which the refrigerator returns to the parameters you set. This prevents accidental freezing of the contents.
| Mode | Temperature range | Duration (auto) | Purpose of use |
|---|---|---|---|
| Normal | +3...+5 °C | Continuous | Daily storage |
| SuperCool | +2 °C (max. cooling) | Up to 12 hours | Loading warm products |
| SuperFrost | -24...-30 °C | Up to 65 hours | Frozen meat, fish |
| EcoMode | +7 °C (cold chamber) | Constantly | Energy saving |
Specific settings of models with two compressors
In two-compressor models Liebherr the temperature settings in the refrigeration and freezer compartments are completely independent. You can turn off one of the cameras while the other continues to work. This is convenient if you are absent for a long time or need to defrost one of the compartments.
Separate buttons or tabs in the menu are used to control each zone. Make sure you are in the correct section before changing settings. The crossed-out thermometer symbol usually means that cooling is turned off in the selected zone.
If one chamber is turned off, the ventilation may change. In some models, it is necessary to open the door of the switched off chamber to relieve pressure or change the operating mode of the dampers. Read the instructions for the specific series CBN, CN, CTP.
⚠️ Attention: If you turn off the refrigerator, be sure to remove all perishable foods. Left food can spoil even at a positive, but not low enough temperature.
Diagnostics and reset settings in case of failures
Sometimes the electronics can malfunction, and the refrigerator will stop responding to commands or will show incorrect data. In this case, a soft reset helps. On most models Liebherr it is performed by long (about 10-15 seconds) holding the settings button or a key combination.
It is better to look for the exact combination for your model in the manual, as it varies. Often this is a simultaneous pressing of the On/Off and Alarmbuttons. After the reset, the device will return to factory settings and you will need to adjust the temperature again.
If after the reset the problem persists and error codes (for example, F1, F2) are displayed on the display, this indicates a malfunction of the sensors or control board. In such cases, adjusting the temperature yourself will not help - you need to call a specialist.
What to do if the display goes out?
If the screen goes out after setting, the screen sleep timer may have triggered. Touch the panel to activate the backlight. If the screen does not light up at all, check the network connection and the integrity of the cord.
Frequently asked questions (FAQ)
Why does the refrigerator not cool immediately after setting?
The compressor and refrigerant take time to change the thermal conditions inside the chambers. This process can take from 2 to 6 hours depending on the load volume and the ambient temperature in the room. Do not open the doors often during this period.
Is it possible to set the temperature below -24 degrees constantly?
Technically, some models allow this, but engineers Liebherr do not recommend this mode for constant operation. This will lead to a significant increase in electricity bills and a reduction in compressor life without noticeable benefit to the quality of storage.
How to understand that the temperature in the chamber has changed?
Modern displays show the set value, rather than the current one in real time. To see the actual temperature, you need to either wait for stabilization, or use models with the function of displaying current readings (often called by long pressing the information button).
Does the position of the EcoMode regulator affect the temperature?
Yes, the mode Eco specially increases the temperature in the refrigerator compartment to +7°C. This is safe for most foods, but critical for meat and milk. Use this mode only when the refrigerator is not fully loaded.
