Modern refrigeration units of the South Korean corporation LG are equipped with advanced control systems that allow the user to independently adjust the climate parameters inside the chambers. The presence of a touch display on the door greatly simplifies interaction with the device, turning the complex setup process into a few touches. However, owners who are encountering such equipment for the first time are often lost in the abundance of buttons and indicators, not understanding exactly how to change the standard factory values.
Correct setting of the temperature regime is critical for the safety of products and the durability of the compressor. If the refrigerator is too warm, bacteria will begin to multiply, causing food to spoil. Excessive refrigeration can freeze vegetables or dry out meat. In this article we will look in detail at how to set the optimal values, what the flashing indicators mean and how to avoid common mistakes when controlling the panel. Control Panel.
It is worth noting that the operating algorithms may differ slightly depending on the specific series of the refrigerator, be it DoorCooling+ or classic models with No Frost. However, the general logic of the interface LG ThinQ remains the same for most devices. Understanding the basic principles will allow you to quickly adapt to any modification and configure the equipment to your needs without contacting a service center.
Principles of operation of the control panel and basic settings
The control panel on the refrigerator door LG is a touch interface that responds to a light touch with a finger. Main screen displays the current temperature in the refrigerator and freezer compartments. In normal operation, the numbers show real degrees inside the chambers, and not the user-specified value, which sometimes causes confusion. To change parameters, you need to activate the editing mode, usually this happens automatically after the first press on the camera selection button.
Most models have separate buttons or touch zones for the refrigerator (Fridge) and freezer (Freezer) compartments. Clicking on the corresponding button allows you to switch the setting mode specifically for this zone. The numbers begin to flash, indicating that they are ready to accept a new command. At this point, using the arrow buttons ◀ and ▶ (or + and -) changes the target temperature value.
⚠️ Attention: After the last press of the setting button, you have approximately 5-10 seconds to confirm the selection. If you do not have time to complete the action, the system will automatically exit the setup mode, saving the previous settings or accepting the changes only partially, depending on the model.
It is important to understand the difference between air temperature and the temperature of the products. Sensors in the refrigerator LG read the air circulating in the chamber. Therefore, changing the settings does not lead to an instant jump in degrees inside the products - this process takes time. Complete stabilization of the temperature after changing the settings may take from 2 to 4 hours, during which the compressor will work in enhanced mode.
Setting the temperature in the refrigerator compartment
The refrigerator compartment is designed for storing products that do not require freezing, but need cooling. The optimal range for most models LG is considered to be from +1°C to +7°C. The factory setting is usually +3°C or +4°C, which is the sweet spot for dairy products, meats and ready meals. Changing this parameter is rarely required, but may be necessary when the chamber is fully loaded or, conversely, when the refrigerator is almost empty.
To adjust the temperature in the main compartment, follow these steps:
- 👆 Press the button
Fridge(Refrigerator) on the control panel - the corresponding indicator will start flashing. - 🔼 Use the up or plus arrow button to increase the temperature, or the down arrow to decrease the temperature.
- ✅ Wait until the flashing stops, or press the mode button again to lock (varies by model).
- 👀 Check that the display shows the value you selected and not the current temperature inside.
When setting very low values (for example, +1°C or +2°C), it is worth considering the risk of freezing of vegetables and fruits located close to the back wall or cold air supply area Multi Air Flow. At the same time, increasing the temperature to +6°C or +7°C is only permissible when storing products with a long shelf life or in conditions where the refrigerator is almost empty. Energy consumption the device directly depends on the set temperature delta: the colder you set the mode, the more often the compressor turns on.
Some advanced models are equipped with a function Express Freeze or Express Chill, which temporarily changes the settings for quick cooling. Do not confuse these modes with a constant temperature setting. If you accidentally activate Quick Cool, the light may remain lit and the temperature drops below the set minimum. To return to normal mode, just press the function button again or reset the settings through the menu.
Adjusting degrees in the freezer
The freezer requires more precise adjustment, since the texture of frozen foods and their shelf life depend on this. In refrigerators LG the standard freezing temperature is -19°C or -20°C. The adjustment range typically ranges from -15°C to -23°C. Lower temperatures (-23°C) are recommended for long-term storage of meat and fish, while -15°C is sufficient for ice cream and semi-finished products that are planned to be consumed in the near future.
The process of setting up the freezer is similar to the refrigerator compartment, but has its own nuances:
- ❄️ Press the button
Freezer(Freezer) on the display. - 📉 Use the navigation buttons to set the desired value, for example -20°C.
- 🕒 Please note that when loading a large volume of warm food, it is recommended to temporarily turn on the mode
Express Freeze. - 🔒 After setting, make sure that the door is tightly closed, since even a small gap will reduce the effort to zero.
Function Express Freeze (Quick Freeze) is a powerful tool that forcibly lowers the temperature in the freezer to a minimum (usually -23°C or -24°C) and keeps it there for 18 hours (or until manually switched off). This is necessary to quickly freeze fresh food without defrosting existing supplies. After completing the cycle or manual shutdown, the function will automatically return the temperature to the value you previously set.
☑️ Check after setting up the freezer
The standard value -18°C..-20°C is quite enough for the safe storage of any products within the recommended periods. An exception may be cases when you make large supplies for several months in advance.
Special modes: Express Cool and Express Freeze
Refrigerators LG offer users special operating algorithms that go beyond simply setting degrees. Mode Express Cool (Fast cooling) is intended for the refrigerator compartment. When activated, the system cools the air in the upper compartment as intensively as possible for 1 hour. This is useful when you have just returned from the store with a full bag of groceries or have placed hot (but cooled down to room temperature) dishes inside.
The mode for the freezer, which was mentioned earlier, works similarly. Its activation causes the compressor to work continuously, ignoring standard rest cycles, in order to reduce the temperature as quickly as possible. Express Freeze for the freezer, which was mentioned earlier. Activating it causes the compressor to run continuously, ignoring standard rest cycles, in order to reduce the temperature as quickly as possible.
| Parameter | Express Cool | Express Freeze |
|---|---|---|
| Chamber | Refrigeration | Freezer |
| Duration | 1 hour (auto) | 18 hours (auto) or manual |
| Purpose | Quick cooling of products | Shock freezing |
| Impact on noise | Possible increase in noise | Noticeable increase in noise |
The use of these modes should be conscious. If you turn on quick freezing, but forget to turn it off (although the timer usually works itself), the refrigerator will work for wear and tear. On models with a display, the activation of these functions is often indicated by the corresponding icon (snowflake or drop with an arrow) lighting up. To turn off the mode before the timer expires, just press the function activation button again.
What happens if you often use Express modes?
Frequent use of fast freezing or cooling modes unnecessarily leads to increased wear on the compressor and an increase in electricity bills. Use them only when actually loading with warm products.
Deciphering indicators and error codes on the display
The display on the refrigerator door LG serves not only for setup, but also for diagnostics. If you see numbers flashing or specific icons light up, this is a signal from the self-diagnosis system. Most often, flashing temperature values mean that current temperature the inside of the chamber is higher or lower than the set one. This is normal immediately after defrosting, a power outage, or loading a large amount of food. After a few hours of operation, the numbers will stop flashing.
However, there are also error codes that require attention. They are usually displayed as an alphanumeric code (for example rF, dS, FF).
- 🔌
rForEr FF: Freezer defrost error. Most often indicates a malfunction of the heater or sensor. - ❄️
dSorEr FS: Freezer temperature sensor error. System cannot read correct data. - 🌡️
Er HS: fridge compartment temperature sensor error.
⚠️ Attention: If error codes starting with
Erappear, self-adjusting the temperature usually does not help. These codes indicate a technical malfunction of the components. It is recommended to disconnect the refrigerator from the power supply for 10-15 minutes. reboot the electronics. If the error persists, you need to call a technician.
The indicator may also light up on the display Lock This is a child safety feature that blocks all buttons on the panel, check if the lock icon is on. unlocking usually requires pressing and holding the button Lock (or a combination of buttons, for example, Fridge + Lock) for 3-5 seconds until a beep is heard.
Frequent problems during setup and their solution
Users often encounter a situation where the installed the temperature does not correspond to the sensations or readings of third-party thermometers. For example, you set it to +4°C, but the food is freezing. This may be due to calibration of sensors or the peculiarities of the placement of the food. Cold air in the refrigerator LG with the system No Frost circulates actively, and in the air outlet area the temperature is always lower than the average temperature in the chamber. sensitive products (greens, open liquids) directly in front of the air duct openings.
Another common problem is the inability to change settings. If the buttons do not respond, check if the control panel lock is activated. It is also worth wiping the display with a dry soft cloth: greasy stains or moisture can interfere with touch interaction. In rare cases, a complete reset of the device by disconnecting the device from the device helps. power supply for 10-15 minutes. This reboots the control module and eliminates software failures.
If the refrigerator operates in extreme conditions. (for example, in an unheated room in winter or in a very hot kitchen), it may not be able to maintain the specified parameters. The technical data sheet of most models regulates the climate class. Operation outside the recommended ambient temperature range may result in the compressor operating continuously, but not reaching the target -18°C or +4°C. LG regulates the climate class. Operating outside the recommended ambient temperature range may result in the compressor running continuously but not reaching the target -18°C or +4°C.
Questions and answers (FAQ)
Why does the temperature flash on the display and a sound signal sound?
Temperature flashing in combination with a sound signal. The signal usually indicates that the refrigerator door has been open for too long or is not closed tightly. The system warns you of a loss of cold. Also, flashing may persist for some time after turning on the refrigerator or after loading warm food until the temperature stabilizes.
How to reset the LG refrigerator to factory settings?
In most models LG there is no separate "Reset" button for temperature settings. To return the parameters to factory values (usually +3°C for the refrigerator and -20°C for the freezer), you just need to manually set these values through the control panel. A complete reset of the electronics is done by unplugging the power cord from the outlet for 10-15 minutes.
Is it possible to set the temperature below -24°C? LG freezer?
No, it is technically impossible to set the temperature below the minimum threshold provided by the software of a particular model. Typically, this limit is -23°C or -24°C. Lower temperatures require industrial equipment. on the display?
What does the "Wi-Fi" or "ThinQ" icon on the display mean?
This indicator reports the status of the refrigerator’s connection to the Wi-Fi network and the smart home system. LG ThinQUsing a mobile application, you can remotely control the temperature, receive notifications about an open door and diagnose faults. If the indicator is flashing, the process of connecting or searching for a network is in progress.
Why does the temperature not change after changing the settings. immediately?
The refrigerator is an inertial system. The air cools quickly, but it takes time to change the temperature of a large volume of food and the walls of the chamber. The compressor works in cycles. If you change the setting from -18°C to -23°C, the compressor will start working more actively, but physical cooling of the contents will take from 2 to 6 hours depending on the load.
