Modern kitchen appliances have ceased to be just a place for cooling food, turning into a complex system for preserving the freshness of products with different microclimate requirements. Technology Flexi Use Boxoccupies a special place in this process, which is often found in models of popular brands, in particular LG. This option is not just an additional drawer, but a full-fledged chamber with the ability to accurately adjust the temperature regardless of the main volume of the refrigerator.
Understanding the operating principle of this compartment can significantly extend the shelf life of delicacies, meat, fish or, conversely, vegetables that require higher storage temperatures. Many owners do not even suspect that their refrigerator is capable of operating in freezer or wine cabinet mode by simply changing the settings of one module. The main advantage of the Flexi Use Box is the ability to switch the operating mode between cooling and freezing with one touch.
In this article we will analyze in detail how to properly operate this compartment, what nuances of setting exist and why ignoring the instructions can lead to to food spoilage. You will learn how to optimally distribute the space inside the chamber and which products absolutely cannot be stored in a certain mode. This knowledge will help you use the potential of your equipment one hundred percent.
Design features and principle of operation
Technologically Flexi Use Box it is an isolated section, equipped with its own cold air supply channel and an independent control system. Unlike standard compartments, where the temperature depends on the operation of the main compressor and the general circulation, this unit has a separate sensor and damper. This allows you to create conditions inside the box that are radically different from the temperature in the main chamber.
The basis of the system is a special fan and heating element (heating element), which work in pairs to maintain the specified parameters. If you select the deep freeze mode, the heating element turns off and the fan blows in the coldest air possible. In cooling mode, on the contrary, the air flow can be limited or mixed with warmer air so as not to freeze the contents.
⚠️ Attention: The design of the seals in this compartment is reinforced, however, if modes are frequently switched from extremely low to high temperatures, condensation may form on the inner wall. This is normal, but requires periodic checking of the drainage hole.
It is important to note that the efficiency of work Flexi Zone directly depends on the tightness of the door closing and the filling of the volume. An empty box cools or freezes faster, but is less stable when opened. The products inside act as cold accumulators, smoothing out temperature surges.
Technical detail
why is the noise heard?: In intensive freezing mode, the Flexi Use Box fan can operate at high speeds, creating a characteristic hum. This is not a malfunction, but the normal operation of the Turbo Cool system.
Main operating modes and temperature ranges
The climate control inside the drawer is carried out through a panel on the refrigerator door or through the display. Typically, the system offers several preset scenarios, each of which is optimized for a group of products. Understanding the difference between them is critical for proper storage.
Mode Meat & Fish (Meat and fish) sets the temperature to about -1...-3°C. In such conditions, products do not freeze into ice, but bacteria do not multiply, which allows you to store fresh meat for several days without loss of taste. The mode Cold Drink (Cooling drinks) raises the temperature to +3...+5°C, preventing liquids from freezing in glass containers, which often happens in conventional freezers.
The mode Fruit & Vegetableis intended for vegetables and fruits, where humidity and temperature (+1...+4°C) are selected so as to prevent withering and rotting. There is also a mode Soft Freezer (Soft freezing) at -5°C, which allows you to store meat in a condition convenient for immediate slicing, without the need for defrosting.
- ❄️ Deep Freeze: extreme cooling to -23°C for quick freezing of large volumes.
- 🍷 Wine Care: gentle mode about +5...+7°C, simulating the conditions of a wine cellar.
- 🥩 Chill: universal mode for short-term storage of prepared dishes.
- 🔋 Eco Saving: energy saving mode with less intensive compressor operation.
Rules for placing products for maximum shelf life
Operating efficiency Flexi Use Box depends not only on the selected setting, but also on how exactly you stack the products. There is a misconception that you can simply stuff the box to capacity, but air circulation is key here. Cold air should wash each product from all sides.
Meat and fish are best placed on special trays or in the bottom of the box to eliminate the risk of juices leaking onto other products. Vegetables and fruits, on the contrary, require free space; If they are stacked too tightly, the lower layers may begin to rot due to lack of ventilation and ethylene release.
It is not recommended to store strong-smelling foods (such as durian or some types of cheeses) in this compartment, along with delicate foods such as butter or prepared desserts, unless the drawer is sealed and completely filled. Odors in a confined space with active air circulation spread instantly.
☑️ Flexi Box loading rules
It is also worth considering the weight. Shelves and drawer guides Flexi Use Box often have load restrictions that are different from the main chamber. Heavy drink bottles or large pieces of frozen meat should be placed closer to the center, avoiding pressure on the plastic walls.
Energy efficiency and impact on refrigerator operation
The use of an additional cooling zone inevitably affects the overall energy consumption of the unit. When you activate the deep freeze mode in Flexi Zone, the refrigerator compressor begins to work more intensively. This is logical, since it is necessary to remove more heat from the isolated volume.
However, modern inverter compressors, which are equipped with most models with this function, can flexibly respond to the demands of different zones. If the temperature in the main compartment has already been reached and cooling is required in the Flexi Box, the system will smoothly increase power, avoiding sudden surges in power consumption.
| Operating mode | Temperature (approx.) | Impact on energy consumption | Recommended time usage |
|---|---|---|---|
| Cooling (Fruit/Veg) | +1...+4°C | Minimum | Continuous |
| Soft freezing | -5°C | Average | Up to 2-3 weeks |
| Deep freezing | -20...-23°C | High | For long-term storage |
| Cooling drinks | +3...+5°C | Low | Constantly |
To save energy, try not to keep the box empty. As mentioned earlier, frozen foods act as cold storage batteries. If you have taken out all the supplies, it makes sense to switch the mode to "Eco" or disable the function completely if it is not used for a long time.
Typical problems and methods for eliminating them
Despite the reliability systems, users may encounter a number of typical situations that are often mistaken for a breakdown. The most common problem is the formation of frost or ice on the back wall of the drawer. This may occur due to the door not being closed tightly or warm food being placed inside.
If you notice that the temperature in Flexi Use Box does not correspond to the set temperature, first check to see if the ventilation holes are blocked by food. It is also worth inspecting the rubber seal for dirt or damage. Even a microscopic gap breaks the seal and nullifies the operation of the entire system.
⚠️ Attention: If the indicator flashes or lights up red, this is a signal that the temperature inside the chamber is higher than normal. Do not load new products until the indicator goes off, otherwise you risk spoiling your existing supplies.
In some cases, uneven cooling may occur: food freezes near the back wall, but gets warmer near the door. This is a physical feature of air circulation. To solve the problem, it is necessary to properly zone the space, placing products that are more sensitive to cold closer to the exit.
Care, cleaning and maintenance of the system
Hygiene in the zone Flexi Use Box requires special attention, since raw products are often stored here. Regular washing of the drawer and interior walls is mandatory. Use mild detergents without abrasive particles to avoid scratching the plastic, where bacteria can grow.
It is recommended to carry out preventive defrosting every six months, even if the model is equipped with a No Frost system. This is necessary to clear the drainage channel, which may become clogged with food particles or mold. Clogged drainage is a common cause of the appearance of puddles of water at the bottom of the refrigerator.
- 🧼 Use a baking soda solution to remove unpleasant odors.
- 💧 Wipe the seals with a dry cloth after each wet cleaning.
- 🚫 Do not use sharp objects to chip ice - this can damage evaporator.
- 🌡️ Before cleaning, be sure to turn off the power to the refrigerator.
After washing, be sure to wipe all surfaces dry and leave the door open for 15-20 minutes to ventilate. The humid environment inside a closed box is an ideal place for the development of mold, which will then be difficult to get rid of.
Can glass bottles be stored in the Flexi Use Box?
Yes, but only in beverage cooling mode (+3...+5°C). In freezing conditions (-5°C and below), glass containers may burst due to expansion of the liquid. Always check the set temperature before loading bottles.
Why is the food in the drawer frozen even though the "Cool" mode is on?
This can happen if the food is lying close to the back wall where cold air comes out, or if the door was not closed properly and the system tried to compensate for the loss of cold by working at the limit. Also check whether the mode is selected correctly on the control panel.
Does the fullness of the main refrigerator affect the operation of the Flexi Box?
Indirectly. If the main volume is overloaded and air circulation is impaired, the overall heat transfer in the system deteriorates, which may force the compressor to work longer to achieve the desired temperature in the additional box.
How to quickly defrost a Flexi Use Box?
Switch the mode to “Cooling” or turn off the function completely. Open the door. Do not use a hairdryer or hot water to speed up the process - a sharp temperature change can damage plastic elements and sensors.
