Modern refrigerators LG equipped with many functions that are designed to make life easier for owners and prolong food freshness. One of these options is mode Quick Freeze, which often raises questions among users when they first read the instructions. This function allows you to freeze a large amount of fresh food in a short time, preserving their structure and beneficial properties.
Unlike the standard freezing mode, which occurs gradually during normal operation of the compressor, fast freezing requires intensive operation of the cooling system. Understanding the principles of operation of this option will help you correctly use the capabilities of your refrigerator and avoid common mistakes when loading the freezer.
In this article we will look in detail at how quick freezing technology works, when it is worth activating it and what nuances exist when operating refrigerators LG with this function. We will also look at how the mode affects energy consumption and temperature conditions inside the chambers.
The principle of operation of the fast freezing mode
Function Quick Freeze (Quick freezing) on refrigerators LG works on the principle of forcibly reducing the temperature in the freezer to minimum values. When you activate this mode, the compressor starts working continuously and at maximum power, ignoring standard shutdown cycles.
This is necessary so that large ice crystals do not have time to form inside the food. It is large crystals that destroy the cellular structure of meat, fish or vegetables, which is why, after defrosting, the product loses its juice, taste and becomes flabby. Fast freezing allows you to create many tiny crystals, which preserves the original structure of the product.
⚠️ Attention: When operating in fast freezing mode, the temperature in the freezer may fall significantly below standard -18°C. Do not leave this mode turned on for a long time unnecessarily, so as not to freeze the reserves already lying there.
It is important to understand that the system No Frost, which is present in most models LG, continues to operate as usual, preventing the formation of ice on the walls while the compressor drives the refrigerant at twice the speed by force. This combination of technologies allows you to achieve the best result.
When it is necessary to enable the Quick Freeze function
The use of the quick freezing mode is justified in specific situations when it is necessary to process a significant volume of warm or chilled products. The normal mode may not be enough if you immediately loaded several kilograms of meat into the freezer after purchasing or harvested berries from the dacha.
Experts recommend activating the function in advance if you are planning to purchase groceries. This will create the necessary temperature reserve. Let's consider the main usage scenarios:
- 🍖 You bought a large amount of fresh meat or fish and plan to divide it into portions for long-term storage.
- 🍓 Harvest season: you need to quickly process and freeze berries, mushrooms or vegetables so that they do not have time to release juice.
- 🍱 Preparing semi-finished products: you have made dumplings, cutlets or cheesecakes and want to put them in the freezer, maintaining their shape and texture.
If you just add a couple of bags of frozen dumplings or ice cream bought on the way home to the freezer, use Quick Freeze is not required. The standard operating mode of the refrigerator LG will be quite enough to maintain the temperature.
How to activate and disable the mode on different LG models
The refrigerator control interface LG may differ depending on the series and year of manufacture of the model. However, the function control logic Quick Freeze remains similar. On models with an external display on the door, control is carried out using touch buttons.
To activate the mode, you usually need to press the button with the corresponding name or a snowflake icon. Some models require you to press the Freeze or Quick Freeze button once to turn it on and again to turn it off. The display will show that the mode is active; a special indicator will often light up.
On models without an external display, where the control panel is located inside the refrigerator compartment or hidden, the algorithm may differ. A combination of buttons or a long hold are often used. Below is a table with control options for different series:
| LG refrigerator series | Panel location | Action to turn on | Indication |
|---|---|---|---|
| LG DoorCooling+ | Touch on the door | Press the Freeze button | The Freeze indicator lights up |
| LG InstaView | Touch on the door | Select Freezer → Quick Freeze | Icon on the screen |
| Classic models | Inside the camera | Hold the Mode button for 3 sec | Sound signal |
| LG Side-by-Side | On the door | Press Freeze (hold 3 sec) | Indicator flashing |
To disable the function, just press the same button again. However, most modern models LG have an automatic timer. After the temperature in the freezer compartment drops to the required minimum (usually about -24°C..-25°C), the refrigerator will automatically return to normal operation.
☑️ Checking the activation of the mode
Impact on energy consumption and compressor life
Many users are afraid that that frequent use of the function Quick Freeze can negatively affect the life of the refrigerator or lead to huge electricity bills. Indeed, in this mode, the compressor LG works without stopping, which increases energy consumption.
However, modern inverter compressorsinstalled in refrigerators LGare designed taking into account such loads. They are able to smoothly increase power and work in intensive mode for a certain time without compromising the resource. Short-term operation at maximum is less harmful for them than constant on-off cycles of the old type.
⚠️ Attention: Although inverter technologies protect equipment, it is not recommended to keep the fast freezing mode on for more than 24-48 hours in a row without a break, unless absolutely necessary.
As for energy consumption, yes, during operating hours Quick Freeze electricity consumption increases. But since the flash freezing process usually lasts a few hours and then the refrigerator automatically switches to an economical keep-warm mode, the overall impact on your monthly budget will be minimal.
Temperature indicators and operating time
In standard operating mode, the freezer compartment of the refrigerator LG maintains a temperature of about -18°C. This is the optimal indicator for long-term storage of frozen products, in which bacteria do not multiply and chemical processes are slowed down.
When activated Quick Freeze the temperature is forcibly reduced to -23°C..-25°C. The time required to achieve such indicators depends on several factors: the current temperature in the chamber, the amount of food loaded and the ambient temperature in the room.
Usually the quick freezing cycle is designed for 24 hours, but often ends earlier. If you loaded warm products, the process may take longer.
Here is the approximate time for freezing various products in the mode Quick Freeze:
- 🥩 Meat (pieces up to 1 kg): 3-4 hours.
- 🐟 Fish (whole or steaks): 2-3 hours.
- 🍒 Berries and fruits (in bulk): 1.5-2 hours.
Common mistakes when using quick freezing
Despite the simplicity of the function, users often make mistakes that negate the effectiveness Quick Freeze. The most common one is loading too much warm food at once. If you place 10 liters of hot soup in the freezer, the refrigerator will work hard, and the quality of freezing in the center of the container will be poor.
Another mistake is violating the packaging rules. Products for quick freezing should be packaged in airtight containers or bags, preferably flat in shape. A thick piece of meat will freeze quickly on the outside, but on the inside the process will go slowly, which will lead to the formation of ice and loss of quality.
Also, do not forget about free air circulation. Even in No Frost mode you don’t need to overcrowd the freezer. The air should freely wash the food from all sides for uniform cooling.
What happens if you forget to turn off the mode?
Modern LG refrigerators have protection. If you forget to turn off Quick Freeze, the system will automatically return to standard mode after 24-48 hours (depending on model). However, if there are foods in the freezer that are sensitive to extreme cold (for example, some types of ice cream or ready-made meals), they may freeze and lose texture.
Comparison with similar functions of other brands
Fast freezing technology is not a unique development LG. Almost every major refrigeration manufacturer has a similar function under its own name. There is no fundamental difference in the physical process; the differences lie in the control algorithms and interface.
For example, in Samsung this function is called Power Freeze, in Bosch — SuperFrost, in Indesit — Fast Freeze. In all cases, the goal is the same: maximum temperature reduction in a short time. Refrigerators LG often use a more “smart” system, which itself analyzes the heat load and regulates the operating time, which distinguishes them from models where the timer is strictly fixed.
It is important to note that the presence of the function Quick Freeze is especially critical for models with the system No Frost. In refrigerators with a drip defrosting system, the air is drier, and quick freezing is even more effective, preventing moisture from “freezing out” of food.
Is it possible to enable Quick Freeze if Is the freezer empty?
Technically, you can turn on the mode, but there is no point in doing so. Without loading products, the compressor will simply cool the air and chamber walls to the minimum temperature, after which it will go into standby mode. This will only lead to unnecessary energy consumption without any benefit.
Why is the Quick Freeze indicator flashing?
A flashing indicator on the control panel LG usually means that the mode is activated, but the target temperature has not yet been reached. As soon as the freezer compartment has cooled down to the required level, the indicator will stop flashing and remain on constantly, or the mode will automatically turn off.
Is it harmful for the food if they stay in the quick freezing mode longer than necessary?
There will be no critical harm, the food will not spoil. However, long-term storage at extremely low temperatures (below -25°C) can lead to excessive dehydration of food (freezer burn) if it is poorly packaged. The texture may become drier.
Is the Quick Freeze setting reset when the power is turned off?
Yes, the settings are reset when the power is completely turned off. After the power supply is restored, the refrigerator LG will start in standard mode. If you have frozen food, you will have to manually reactivate the function Quick Freeze.
Does Quick Freeze work in Eco mode?
When you activate the Quick Freeze function, the refrigerator temporarily exits energy-saving mode Ecoas the priority becomes cooling speed rather than energy savings. After the freezing cycle is completed, the device can return to economical settings, if they were set.
