Modern brand refrigerators LG equipped with many intelligent functions designed to make life easier for the user and extend the shelf life of products. One of these useful options is the Quick Freezemode, which literally translates as “quick freezing”. Many equipment owners see this button on the control panel, but do not always understand its real purpose and mechanics of operation, mistakenly believing that it simply speeds up the cooling of the chamber.
In fact, this function hides a complex algorithm for the operation of the compressor and the refrigerant circulation system. When you activate this mode, the refrigerator goes into forced operation mode, ignoring the standard engine shutdown cycles. This allows you to quickly reduce the temperature in the freezer, which is critical for preserving the structure of products and their beneficial properties when storing a large volume of fresh food.
In this article we will analyze in detail exactly how it works Quick Freeze, in what situations it should be used, and when activating the function will be a waste of electricity. Understanding the operating principles of your equipment LG will allow you to operate it more efficiently and carefully.
The principle of operation of the fast freezing function
The function Quick Freeze in refrigerators LG works on the principle of forced continuous operation compressor. In normal mode, the refrigerator cools the chamber to a set temperature, after which the compressor turns off or reduces speed (in inverter models), waiting for the temperature inside the chamber to rise. When fast freezing is turned on, this cycle is interrupted.
The equipment switches to maximum performance mode, pumping cold air into the freezer compartment without stopping. This leads to a sharp drop in temperature, which allows the water contained in the products to freeze faster. The key feature is that during rapid freezing, tiny ice crystals are formed that do not destroy the cellular structures of the products.
It is important to note that in some models LG s The system No Frost also enhances the operation of fans for more intense airflow. However, it is worth remembering that this mode creates additional load on the engine, so its use must be justified.
⚠️ Attention: Prolonged operation of the compressor in forced freezing mode leads to increased energy consumption. Do not leave the function turned on unnecessarily for more than 24 hours.
When it is necessary to activate Quick Freeze
Using the quick freezing mode is not always relevant, but only in special situations related to loading the chamber with warm or room temperature products. The main goal is to pass the “critical zone” of temperatures as quickly as possible in order to maintain the quality of food.
Most often, the function is turned on before storing a large amount of fresh food, for example, after going to the market or purchasing meat for future use. If you place a large amount of food at room temperature in normal mode, the refrigerator will take a long time to restore the temperature balance, and the top layer of food may begin to deteriorate before it freezes completely.
The mode is also useful if you plan to freeze berries, mushrooms or fruits, which, when slowly frozen, lose their juice and turn into porridge when defrosted. A quick hit of cold “seals” the vitamins inside.
- 🍖 You have purchased a large amount of fresh meat or fish for long-term storage.
- 🍓 It is necessary to preserve the structure of soft berries, fruits or vegetables.
- 🥟 You have prepared semi-finished products (dumplings, cutlets) and want them freeze.
- 🥛 You need to quickly cool drinks or food before serving (in some models).
Instructions: how to turn the mode on and off
Control the function Quick Freeze in refrigerators LG may differ depending on the series and type of control panel (touch or push-button). In most modern models, the activation process takes a few seconds and does not require complex manipulations.
To turn it on, you need to find a button on the control panel with the appropriate name or a snowflake icon. After pressing, the indicator should light up on the display, signaling the transition to active mode. In some models, you need to hold the button for 3 seconds to activate.
☑️ Quick Freeze activation algorithm
As for shutdown, there are two scenarios. In older models, the function must be turned off manually by pressing the button again after the food has frozen. In newer models with intelligent control, the refrigerator itself will turn off the mode after a certain time (usually 24 hours) or after reaching the target temperature, which will be signaled by the indicator going off.
The sequence of actions for manual control often looks like this: press Freeze or Quick Freeze on the panel. If the indicator is on, the mode is active. To deactivate, press the same button again until the indicator goes out.
The influence of the mode on the safety of products
The main advantage of using Quick Freeze lies in the biochemical processes occurring inside the products during freezing. The quality of frozen food directly depends on the rate of passage of the temperature range from 0°C to -5°C, which is called the zone of maximum crystal formation.
During slow freezing, the water inside the cells of the product turns into large, sharp ice crystals. These crystals tear apart cell walls. When you defrost such a product, the cell sap flows out, and along with it the vitamins, minerals and taste go away. The meat becomes dry, and the berries turn into puree.
The mode LG Quick Freeze allows you to bypass this zone so quickly that the water does not have time to form large crystals. Microcrystals are formed, which are distributed evenly and do not damage the cell structure. After defrosting, the product retains the appearance, taste and benefits of its fresh counterpart.
⚠️ Attention: Do not re-freeze defrosted products, even using the quick freezing mode. This leads to irreversible changes in the structure and the proliferation of bacteria.
Comparison of refrigerator operating modes
To better understand the difference between the normal operation of the refrigerator and the fast freezing mode, it is worth considering their parameters in comparison. This will help you take a conscious approach to controlling equipment LG.
| Parameter | Normal mode | Quick Freeze |
|---|---|---|
| Compressor operation | Cyclic (on/off) | Continuous |
| Temperature in the chamber | Stable (about -18°C) | Decreases to -24°C and below |
| Electricity consumption | Standard | Increased |
| Freezing time for 1 kg of product | Long (several hours) | Minimum |
As can be seen from the table, the difference in temperature and intensity of engine operation is significant. That is why manufacturers do not recommend keeping the refrigerator in Quick Freeze mode constantly.
What happens if you forget to turn off Quick Freeze?
If you leave the Quick Freeze mode on for several days, the compressor will work without rest. This can lead to overheating of the engine, shortening the life of the equipment and significantly increasing electricity bills. In modern LG models, automatic shutdown will work after 24 hours to protect the system.
Energy consumption and resource saving
Using the quick freezing function inevitably leads to an increase in energy consumption. The compressor, working without stopping, consumes the maximum amount of energy for which it is designed. However, if you use the function correctly, this will not become a financial problem.
The savings lie in the fact that you spend more energy in a short time, but get a high-quality frozen product that does not have to be thrown away due to loss of taste. In addition, after turning off the mode, the refrigerator will return to normal operating mode, and energy consumption will be normalized.
For owners of inverter compressors LG the load will be less noticeable than for conventional models, since the inverter is able to smoothly regulate power, but in the mode Quick Freeze it will also reach maximum rpm.
Frequently asked questions and possible problems
Users often encounter a situation where the indicator is on, but the food does not freeze as quickly as expected. This may be due to camera overload or a malfunction of the heat dissipation system. It is also important to check the tightness of the door.
Sometimes after turning off the mode, the temperature in the chamber may rise briefly until the system stabilizes. This is a normal process of equalizing temperature readings.
If you notice that the mode Quick Freeze does not turn on or turns off immediately, check if the freezer door is open. An open door sensor blocks the activation of forced modes.
Is it possible to turn on Quick Freeze in an empty refrigerator?
Technically it is possible, but there is no point in doing so. This function is designed for freezing food. Idle operation will only waste electricity without any benefit for the equipment or contents.
How long does the mode work automatically?
In most modern models LG with electronic control, the automatic shutdown timer is set to 24 hours. After this, the indicator goes out and the refrigerator returns to normal mode.
Is frequent use of quick freezing harmful for the compressor?
If you follow the instructions and use it wisely, no. However, turning on the mode daily for several hours can reduce the engine life faster than normal operation.
Why is the indicator on, but the food is not frozen?
Perhaps you loaded too much warm food at the same time, or the door was not tightly closed. Also check if the air ducts in the freezer are clogged.
