Owners of modern refrigeration equipment from a German brand Liebherr often face questions about the advanced functionality of their devices. The control panel can contain many buttons, and one of the most intriguing for users is the Cool Pluskey. This feature is not standard on all models, but where it is present, it plays an important role in organizing food storage. Understanding its purpose helps to use the refrigerator's potential to 100%.
Many people confuse this mode with the quick freezing or super-cooling function, but Cool Plus has a completely different task. It is designed specifically to optimize temperature conditions in certain areas of the refrigerator compartment. This is not just a marketing ploy, but a technological solution that allows you to prolong the freshness of specific categories of products. In this article we will analyze in detail how exactly this option works and when it is advisable to activate it.
The main purpose of the Cool Plus function
The function Cool Plus is created in order to provide a lower temperature in a certain part of the refrigerator compartment, usually in its upper zone. Unlike the standard operating mode, where the cold is distributed evenly throughout the entire volume, activating this option changes the operating algorithm of the compressor and air circulation system. This allows you to create conditions that are ideal for storing products that require special temperature conditions.
⚠️ Attention: Do not confuse Cool Plus with the SuperCool function. The latter is designed for rapid cooling of newly loaded products, while Cool Plus is a long-term storage mode for specific products.
The main purpose of use Cool Plus mode consists of creating a zone with a temperature of about 2°C, which is below the standard 5-7 degrees in the main chamber. Such conditions are necessary for perishable products that quickly lose their properties during normal refrigeration. This is especially true in the summer or when the refrigerator is not fully loaded, and the standard cycle may not be enough to maintain ideal cold in the upper tiers.
Using this function can significantly extend the shelf life of deli meats, cheeses and ready meals. Without activation Cool Plus these products may begin to spoil faster, losing taste and texture. Thus, the button serves as a tool for fine-tuning the climate inside your refrigerator to the current needs of the user.
Operating principle and temperature zones
The operating principle of the system Cool Plus is based on the redistribution of cold flows air. In refrigerators Liebherr with this function, the ability to change the direction or intensity of the cold supply is structurally provided. When you press the corresponding button on the control panel, the electronics give a command for enhanced cooling of the upper part of the refrigerator compartment.
Usually the standard temperature in the refrigerator compartment is maintained at +5°C. When activated Cool Plus the temperature in the upper zone (often a shelf under the freezer or a special compartment) is reduced to +2°C...+3°C. This creates a so-called “cold zone” that simulates the conditions of professional refrigerated display cases.
It is important to understand that the lower shelves and drawers can maintain a standard temperature so that the vegetables and fruits stored there are not exposed to too low temperatures. This differentiation allows products with different climate requirements to be stored in one device. The system automatically controls the operation of the compressor to prevent freezing of products in the zone Cool Plus.
- ❄️ Activation of the mode reduces the temperature in the upper compartment to +2°C.
- 🌡️ The lower zones remain in the standard temperature mode for vegetables.
- ⏱️ The system operates cyclically, maintaining the set parameter is constant.
Which products are best stored in the Cool Plus mode
Not all products require such low temperatures, so it is important to know what exactly should be placed within the range of the function Cool Plus. First of all, these are perishable goods of animal origin, which are most susceptible to bacteria at temperatures above +4°C. Proper placement of products in this zone allows you to keep them fresh for several days longer than usual.
This category includes semi-finished meat products, minced meat, chilled meat and poultry. Also ideal candidates are soft cheeses, curd products and prepared culinary products such as salads with mayonnaise or cold cuts. Fish and seafood, if they are not intended for freezing, are also much better preserved. Cool Plus.
However, you should be careful with products that do not like extreme cold. For example, some types of vegetables and fruits may lose their taste or texture at +2°C. Therefore, the zone Cool Plus should be used selectively, focusing on the type of loaded products.
| Product type | Recommended mode | Shelf life (approximate) |
|---|---|---|
| Chilled meat | Cool Plus (+2°C) | up to 3-4 days |
| Fish and seafood | Cool Plus (+2°C) | 1-2 days |
| Ready meals/Salads | Cool Plus (+2°C) | 2-3 days |
| Vegetables and fruits | Standard (+5...+7°C) | up to 7-10 days |
How to activate and deactivate the mode
Function control Cool Plus in refrigerators Liebherr is carried out through the panel control located on the door or inside the chamber, depending on the model. The activation process is as simple as possible and does not require complex settings. Usually, to turn it on, you need to press the corresponding button, after which the indicator will light up, indicating that the mode is operating.
⚠️ Attention: The control panel interface may differ depending on the series of the refrigerator (for example, Comfort, Premium or Smart Device). Always check the instructions for your specific model, as the location of the buttons may vary.
be oriented.
To activate the mode, press the button Cool Plus once. The indicator will light up to confirm that the function has started. To turn off the mode, you must press the same button again. In some models with electronic control, shutdown may occur automatically after a certain time or when the door is opened, if this is provided by the algorithm.
☑️ Checking the operation of the Cool Plus mode
Differences from other cooling functions
Users often wonder what the difference is between Cool Plus, SuperCool and SmartCool. Understanding these differences helps you manage your refrigerator effectively. SuperCool is an intensive short-term cooling mode that is used immediately after loading a large batch of room temperature products. It operates at maximum power to quickly reduce the temperature, and then automatically turns off.
In contrast, Cool Plus is a mode of constantly maintaining a lower temperature in a certain zone. It is not intended for rapid cooling of hot products, but serves to create stable storage conditions. SmartCool, in turn, automatically adjusts the temperature depending on the frequency of door opening and the amount of food, working in the background.
Technical details of the compressor
In Cool Plus mode, the compressor can operate with more frequent but shorter cycles switching on to maintain a stable low temperature in the upper zone without freezing the rest of the volume.
Thus Cool Plus occupies its niche as a tool for specific storage, while other functions solve problems of household cooling or energy saving. Using each of them in the appropriate context ensures better food preservation.
Energy consumption and impact on the operation of the refrigerator
Use of the function Cool Plus inevitably affects the energy consumption of the refrigerator. Since more intensive compressor operation is required to maintain a temperature of +2°C, energy consumption may increase slightly. However, modern models Liebherr equipped with effective insulation systems and inverter-type compressors, which minimizes this increase.
It is important to note that constant use of the mode Cool Plus unnecessarily can lead to increased wear of the equipment. It is recommended to activate this function only when you actually store products that require such conditions. The rest of the time, the standard cooling mode is quite sufficient for most food stocks.
Possible problems and their solutions
Despite the reliability of the equipment Liebherr, users may encounter situations where the function Cool Plus does not work correctly. For example, the indicator is on, but the temperature does not decrease. This may be due to the refrigerator being overloaded with food that is blocking air circulation. It could also be due to the door not closing tightly or the vents being dirty.
⚠️ Attention: If you notice that food in the Cool Plus zone is starting to freeze and the indicator is on, there may be a malfunction in the temperature sensor. In this case, it is recommended to turn off the mode and contact the service center.
To diagnose the problem, try unplugging the refrigerator for 10-15 minutes, then turning it on again and activating it. Cool Plus. If the problem persists, check to see if the vents are blocked by food. Also make sure that the refrigerator is installed level and has sufficient clearance from the wall for normal operation of the cooling system.

- 🧊 Make sure that the ventilation holes are not blocked by food.
- 🔄 Reboot the device to reset possible errors electronics.
FAQ: Frequently asked questions
Is it possible to store vegetables in the Cool Plus mode?
Storing vegetables in the Cool Plus mode is not recommended. Temperatures of +2°C may be too cold for most vegetables and fruits, causing them to lose moisture and change texture and taste. For vegetables, it is better to use the bottom drawers of the refrigerator, where the standard temperature is maintained.
How long can you keep Cool Plus turned on?
Technically, the mode Cool Plus can be kept on constantly, if necessary (for example, you store a lot of meat products). However, to save energy and the life of the compressor, it is recommended to turn it on only when necessary.
Why is the Cool Plus indicator flashing?
A flashing indicator usually signals a temperature change process or a malfunction. If the flashing continues for a long time after activation, this may indicate that the refrigerator cannot reach the set temperature due to high ambient temperature in the room or overload.
Does Cool Plus affect the operation of the freezer?
Function Cool Plus primarily affects the refrigerator compartment. However, since it uses a compressor, this can indirectly affect the operation of the freezer, especially if the refrigerator has a single compressor. In most cases, the system itself balances the load, but during prolonged operation in extreme conditions, the freezing efficiency may decrease slightly.
Do you need to turn off Cool Plus at night?
This is not strictly necessary if you store products that require low temperatures. However, if the refrigerator is loaded only with a standard set of products (drinks, sauces, vegetables), turning off the mode at night will help save energy.
