Modern household appliances are overcrowded functionality that is designed to make the user's life easier. Among the many buttons on the control panel of brand refrigerators LG there is often a key with the inscription Quick Freeze. Many owners, when encountering this option for the first time, do not fully understand its purpose and are afraid to press too much for fear of breakdown or excessive power consumption.
In fact, this function is an accelerated freezing mode that activates the compressor at maximum power. This is not just a marketing ploy, but a useful tool for certain situations that require quickly reducing the temperature in the freezer. Understanding the principle of operation of this mode will help you use the equipment more efficiently.
In this article we will take a detailed look at how the system works Quick Freezewhen it should be turned on and why it automatically turns off after a certain time. You will learn about the nuances of operation that will help maintain food freshness and extend the life of your refrigerator.
The principle of operation of the accelerated freezing mode
Function Quick Freeze (quick freezing) on refrigerators LG works by forcibly increasing the performance of the compressor. During normal operation, the unit maintains the set temperature, turning on and off as needed. When accelerated freezing is activated, the system ignores standard rest cycles and works continuously, pumping cold air into the freezer compartment.
This leads to a sharp drop in the temperature inside the chamber, which allows the water contained in the products to crystallize as quickly as possible. The rapid formation of small ice crystals prevents the destruction of the cellular structure of products, preserving their taste and beneficial properties after defrosting. It is this physical process that underlies the effectiveness of the mode.
However, it is worth considering that working in this mode creates an increased load on the main components of the refrigerator. The compressor and refrigerant circulation system are operating at their maximum capacity. Therefore, manufacturers do not recommend using this function constantly, unless there is a real need.
It is important to understand the difference between regular cooling and blast freezing. If the standard mode simply maintains cold, then Quick Freeze actively fights the heat introduced by new products. This is especially true for models with a No Frostsystem, where the uniformity of cold distribution plays a key role.
⚠️ Attention: Prolonged operation of the compressor at maximum power mode leads to increased energy consumption. Do not leave the function turned on longer than is really necessary.
Technically, the process is implemented through changing the electronic module control algorithms. Temperature sensors record changes, but priority is given to the forced cooling command. This allows you to reach a temperature of -24°C and below in a short period of time, while the normal mode can cope with this for hours.
When it is necessary to activate the Quick Freeze function
The use of the accelerated freezing mode is justified in specific situations when quick intervention in the temperature regime of the chamber is required. Most often, users resort to this function when loading a large volume of fresh, not yet frozen products. If you brought home several kilograms of meat, fish or berries from the dacha, standard refrigeration may not be enough.
The second common situation is preparing for a long absence. If you are going on vacation and want to be sure that the food in the freezer will not spoil even with possible short-term power surges or rare openings of the door by family members, pre-activation Quick Freeze will create a supply of cold.
The mode is also useful if you notice that the temperature in the chamber has risen above normal after defrosting or opening the door for a long time. In this case, the function will help to quickly return the indicators to the set values.
Do not forget about seasonal preparations. During the harvest season or when purchasing food in bulk, when the freezer is almost completely full, the normal mode may not cope with heat stress. Food in the center of the chamber may begin to deteriorate while the outer layers are already frozen. Quick Freeze solves this problem.
Instructions for turning the mode on and off
Control of the quick freezing function on refrigerators LG is usually carried out through the control panel located on the outside of the door or inside the refrigerator compartment, depending on the model. The interface can be touch or push-button, but the logic of actions remains similar for most devices.
To activate the mode, you need to find a button with the corresponding designation. Often it is signed as Quick Freeze or has a pictogram in the form of a snowflake with numbers. Pressing this button puts the refrigerator into intensive operation mode. An indicator should light up on the display, indicating that the function has been activated.
The activation process can be described by the following algorithm:
- 🔘 Find the button
Quick Freezeor the freeze icon on the control panel. - 🔘 Press and hold the button for 3 seconds (on some models this is enough press briefly).
- 🔘 Wait for the indicator light to appear on the display confirming activation.
- 🔘 Load the food into the freezer, trying to distribute it evenly.
However, some older or basic models may require manual shutdown. To do this, you need to press the same button again until the indicator goes out.
☑️ Checking the activation of the mode
If you cannot find the button or it does not respond, perhaps in your model this function is activated through the settings menu. In this case, use the navigation buttons to go to the section Settings or Settings, where select the item Freeze Control.
Automatic shutdown and operation timer
One of the key features of modern refrigerators LG is the presence of an intelligent mode control system. The Quick Freeze function is not designed to work endlessly. Most models have a built-in timer that automatically deactivates the accelerated freezing mode.
The standard operating time of the mode is about 20 hours. This time is enough to completely freeze a standard load of food and stabilize the temperature. After this period has expired, the refrigerator automatically returns to the previously set temperature settings.
Automatic shutdown protects the compressor from overheating and wear. If the mode worked constantly, the engine life would be significantly reduced. In addition, this prevents waste of electricity, since maintaining ultra-low temperatures requires more energy than simply storing frozen food.
In some advanced models with artificial intelligence Smart Diagnosis operation time may vary. The electronics analyzes the current temperature in the chamber and the amount of heat inflow, making a decision to turn off the function earlier or (less often) later than the standard time.
What will happen if you do not turn off the mode manually on the old model?
In old refrigerators without automatic shutdown, the compressor will work continuously, which will lead to the formation of excess ice, possible freezing of the evaporator and a significant increase in bills for electricity.
The user is recommended to control the process. If you see that the food is already frozen and the indicator is on, it is better to forcefully turn off the function without waiting for the timer to end. This will be a careful attitude towards equipment.
The influence of the regime on the safety of products
The main purpose of use Quick Freeze — maintaining the quality of products. During slow freezing, the water contained in the cells of meat, fish, vegetables or fruits turns into large ice crystals. These crystals have sharp edges that rupture cell membranes.
When such a product is defrosted, cell juice flows out, taking with it vitamins, minerals and taste. The meat becomes dry and the berries turn into mush. The fast freezing mode allows you to avoid this negative effect.
Due to a sharp decrease in temperature, the moisture in the food crystallizes instantly, forming many microscopic crystals. They do not damage the cell structure. As a result, after defrosting, the product retains its original shape, texture and taste.
This is especially critical for:
- 🥩 Fresh meat and poultry - juiciness is maintained during cooking.
- 🐟 Fatty fish - fat oxidation and the appearance of unpleasant food are prevented odor.
- 🍓 Berries and fruits - they remain whole, without turning into puree.
- 🥦 Vegetables and herbs - color and elasticity are preserved.
Using the function Quick Freeze also helps prevent the spread of odors. Quick “sealing” of the product with a crust of ice blocks the release of volatile substances, which is especially important in small-volume chambers.
Comparison of refrigerator operating modes
To better understand the place of the function Quick Freeze in the operation of the refrigerator, it is useful to compare it with other operating modes. Users often confuse accelerated freezing with the “Vacation” mode or regular super-cooling.
The table below shows a comparison of the main characteristics of various operating modes of refrigerators LG:
| Parameter | Quick Freeze | Normal mode | Vacation mode (Eco) |
|---|---|---|---|
| Purpose of use | Quick freezing of fresh food | Daily storage | Long-term absence of owners |
| Temperature in the freezer | Up to -24°C and below | -18°C.. -20°C | -18°C (standard) |
| Temperature in the refrigerator compartment | No change / +5°C | +3°C.. +5°C | +15°C (energy saving) |
| Energy consumption | Maximum | Average | Minimum |
| Operation duration | Cycically or up to 20 hours | Continuously | Continuously |
The table shows that Quick Freeze is a tool for solving specific, local problems, and not for continuous operation. The “Vacation” mode, on the contrary, is designed to save energy when the refrigerator compartment is not in use, but the freezer must work.
Some models also have a function Express Freeze, which is analogous to Quick Freeze, but may have slightly different operating algorithms depending on the series of the refrigerator. The essence remains the same - maximum power for speed.
Frequently asked questions and possible problems
Despite the simplicity of control, users sometimes have questions related to the operation of the accelerated freezing mode. Often they relate to noise, indicators or the inability to turn on a function.
One of the common problems is when the button Quick Freeze does not respond to pressing. In most cases, this is due to the control panel being locked (Child Lock). If the lock icon is lit on the display, you must unlock the panel, usually by long pressing the corresponding button, before activating the freeze.
Users may also be bothered by increased noise. When operating in fast freezing mode, the compressor and system fans No Frost work harder. This is a normal phenomenon, but if the noise is accompanied by vibration or knocking, it is worth checking the stability of the refrigerator installation.
Sometimes a problem occurs when the mode does not turn off automatically. This may indicate a malfunction of the temperature sensor or a malfunction in the electronic module. In this case, it is recommended to reboot the refrigerator by unplugging it for 10-15 minutes.
⚠️ Attention: If the indicator Quick Freeze flashes, but the mode does not turn on, this may indicate a malfunction of the heat removal system or a problem with the sensor. Contact the service center.
Do not be alarmed if, after turning off the mode, the temperature in the chamber begins to rise slowly. This is a natural process of entering the work cycle. The main thing is that it does not exceed critical values (-15°C) for a long time.
Is it possible to leave the Quick Freeze mode on all the time?
Strongly not recommended. Constant operation at maximum power will lead to rapid wear of the compressor, increased energy consumption and possible freezing of the evaporator, which will disrupt air circulation.
Why does the Quick Freeze function not turn on?
There may be several reasons: the child lock is activated, the freezer door is open, the system has already reached the minimum temperature, or there is technical malfunction of the sensors.
How long does it take to completely freeze 5 kg of meat?
In the mode Quick Freeze the process takes about 2-4 hours depending on the initial temperature of the product and the model of the refrigerator. In normal mode, this would take more than 10-12 hours.
Does the fast freezing mode affect the food in the refrigerator compartment?
In modern two-compressor models there is no effect. In single-compressor refrigerators, a slight short-term decrease in temperature in the refrigerator compartment is possible, but the control system usually compensates for this.
