Modern refrigerators of the German brand Liebherr are famous for their energy efficiency and a well-thought-out microclimate control system inside the chambers. However, after purchase or first use, users are often faced with the need to manually adjust factory settings. Correct setting of the temperature regime is not just a matter of comfort, but also a guarantee of food safety, as well as the durability of the compressor.
Unlike budget models, where control is limited to a rotary knob, equipment Liebherr offers complex electronic systems with displays, touch panels and even control via a smartphone. In this article, we will analyze in detail the setting algorithms for various series, explain the purpose of special functions and help to avoid common mistakes during operation.
Incorrectly set parameters can lead to freezing of vegetables or, conversely, to spoilage of meat products due to insufficient cooling. Therefore, it is important to understand the operating logic of your particular model. electronic control unit exactly your model.
Determining the type of control panel
Before proceeding with the settings, you need to identify the type of interface your device is equipped with. In the manufacturer's model range there are three main types of control: fully electronic with an external display, internal electronic (hidden) and mechanical. The sequence of your actions depends on this.
Models with an external display located on the door are the most common in the Premium and Comfort series. Here, all parameters are visible at once, and adjustments are made by touching the sensors or pressing the buttons under the screen. Touch buttons require a light but confident touch, often accompanied by a sound signal.
In simpler or built-in models, the control panel may be located inside the refrigerator compartment, usually on the side wall or under the ceiling. This is done to preserve the aesthetics of the facade. Mechanical regulators (thermostats) are found in older or basic models and represent a scale with divisions from 1 to 5 or 7.
⚠️ Attention: If the indicators are flashing on the display or an exclamation mark is on, this may not indicate the need for adjustment, but a malfunction or an alarm (for example, the door has been open for a long time). In this case, first eliminate the cause of the alarm.For owners of models with mechanical control, it is important to remember: the numbers on the scale do not mean degrees Celsius. These are conventional units of cooling power. Turning the knob towards a higher number increases the cold, but does not guarantee the exact temperature value.
Setting the temperature in the refrigerator compartment
The optimal temperature for storing most products in the main chamber is considered to be the range from +3°C to +5°C. It is under these conditions that the growth of bacteria slows down, but the food does not freeze. In refrigerators Liebherr with a system NoFrost or SmartFrost the cold distribution occurs evenly, but the area at the back wall is always colder.
To set the desired values on models with a display, you must activate the editing mode. This is usually done by long (about 3-5 seconds) pressing the button with the image of a thermometer or the symbol of the corresponding camera. After activation, the current readings begin to flash on the screen, and you can change them using the “plus” or “minus” buttons.

AutoMode, the equipment itself can maintain the optimal mode depending on the frequency of door opening and loading. However, manual is sometimes necessary, for example, after loading a large amount of warm products.
- 🌡️ For storing fresh meat and fish, it is recommended to set the temperature closer to 0°C...+2°C, using a special zone VarioZone or ZeroDegree, if it is provided for by the design.
- 🥛 It is better to store dairy products and ready meals at a stable +4°C, avoiding proximity to the back wall, where there is a risk of freezing.
- 🍺 Drinks and foods with a long shelf life can be placed in areas with temperatures up to +7°C, usually these are the top shelves or door niches.
⚠️ Attention: Do not set the minimum possible temperature (+1°C or +2°C) on a constant basis unless necessary. This significantly increases the load on the compressor and leads to excessive consumption of electricity, and can also dry out the vegetables.Adjusting the freezer compartment
The freezer compartment in the appliance Liebherr requires separate adjustment. The standard value for long-term storage is -18°C. At this temperature, products retain their properties for up to 12 months. Reducing the temperature to -24°C or -26°C only makes sense in the fast freezing mode.
The setting is carried out in the same way as the refrigerator compartment: select the snowflake or freezer symbol on the display, wait until the indicator blinks and change the value. In two-compressor models (DuoCooling), the chamber temperatures are regulated absolutely independently of each other.
☑️ Checking the freezer settings
Done: 0 / 4It is important to distinguish between storage and freezing modes. If you have loaded the chamber with fresh food that needs to be frozen quickly, use the function
SuperFrost. It temporarily lowers the temperature to a minimum, and then automatically turns off after 65 hours or manually.
Mode Temperature Purpose Duration Storage -18°C Long-term storage of frozen foods Continuously SuperFrost -24°C...-26°C Quick freezing of fresh foods Auto (65 hours) or manually EcoMode -15°C...-16°C Energy saving when fully loaded As needed SmartFrost Depends on the model Ice reduction system Constantly (design) Remember that frequent opening of the freezer door negates efforts to maintain low temperatures. In models with the system Liebherr SmartFrost ice formation is minimal, but is not completely excluded at high indoor air humidity.
Use of special modes: SuperCool and MyMode
Engineers Liebherr have developed a number of intelligent functions for various use scenarios. One of the most useful is the
SuperCoolmode. It is designed to quickly cool a large number of products just brought from the store.When activated SuperCool the refrigerator operates at maximum power for 6 hours, after which it automatically returns to the previously set settings. This prevents the heating of products already inside due to heat gain from a new load.
What happens inside during SuperCool mode?
In this mode, the compressor operates continuously, and fans (if any) increase the speed of air circulation. The temperature in the chamber can briefly drop to +2°C, so do not leave this mode on for a long time unless necessary, so as not to freeze vegetables and herbs.
Another interesting feature is MyMode. It allows the user to program individual settings for special occasions, such as a party when intensive cooling of drinks is required, or for holidays when the refrigerator is almost empty.
- 🎉 Party Mode: Intensively cools drinks in the door shelves and quickly restores the temperature after frequent opening.
- ✈️ Holiday Mode: Increases the temperature in the refrigerator compartment to +14°C or +15°C to save energy and prevent the appearance of odor while the freezer is operating in normal mode.
- ❄️ Deep Freeze: An analogue of SuperFrost, but with the ability to manually adjust the duration and temperature for professional freezing.
These modes are usually activated by a separate button on the control panel. The corresponding indicator lights up on the display. Don't forget to turn it off Holiday Mode after returning from vacation so that the food in the main chamber does not spoil.
Calibration and working with sensors
Sometimes users are faced with a situation where the set temperature does not match the real one. This may be due to the calibration of the sensors or the placement of the thermometer for testing. In refrigerators Liebherr sensors are located in air recirculation zones, and not at random points in the chamber.
If you measure the temperature with a regular household thermometer, place it in a glass of water (for the refrigerator) or between bags (for the freezer) and leave for several hours. Instant air measurements often give a distorted picture due to the cyclic operation of the unit.
Some models have a calibration function for the displayed temperature, but it is hidden in the service menu and is not intended for the average user. If the difference between the display readings and reality exceeds 3-4 degrees, the sensor probably needs to be replaced or refilled with freon.
⚠️ Attention: Disassembling the control panel yourself or attempting to “tighten” the sensors may void the warranty. If you suspect a malfunction of the cooling system, contact an authorized service center.External factors also affect the accuracy of the readings: direct sunlight hitting the case, or the proximity of heating devices. Make sure that the refrigerator is level, and the gap between the back wall and the wall is at least 5-7 cm for normal ventilation of the condenser.
Frequently asked questions (FAQ)
Why does the temperature indicator flash after turning on?
Flashing of the indicator and a sound signal means that the set temperature inside the chamber has not yet been reached temperature. This is normal when first turned on or after defrosting. Press the acknowledgement button (bell or key symbol) to mute the sound. The flashing will stop when the refrigerator enters mode.
How to turn on the “Vacation” mode on a Liebherr refrigerator?
On models with a display, find the button with a palm tree or the inscription
Holiday. Press and hold it for a few seconds until the corresponding symbol appears on the screen. In models without a display, the instructions may differ - you often need to set the regulator to a special position or combination.Is it possible to change the temperature via a smartphone?
Yes, if your model supports the technology Liebherr SmartDeviceBox or has a built-in Wi-Fi module. To do this, you need to download the application Liebherr HomeConnect or SmartDevice, register the device and connect it to your home network.
What to do if ice has formed in the chamber with the correct settings?
Check the tightness of the door seal and whether the chamber is overloaded. If the system SmartFrostis used, a small amount of frost is acceptable and is removed during periodic defrosting. There should be no ice in the systems - this is a sign of a malfunction of the defrost or heating element. NoFrost There should be no ice - this is a sign of a malfunction of the defrost or heating element.
