The question of how to turn off the freezer compartment in a two-chamber LG refrigerator often arises among users who need to increase the usable volume of the refrigerator compartment or switch the equipment to storage mode for storing only fresh food. Two-chamber units They are more complex than single-cabinet models, and completely turning off one of the cooling circuits here has its own technical features. It is important to understand that in most modern LG models equipped with the system No Frost, it is structurally impossible to physically turn off the compressor only for the freezer, leaving the main circuit running.
However, there are software methods and operating modes that allow you to minimize the production of cold in the lower chamber or, conversely, freeze products, and then switch to economy mode. In this article, we will analyze in detail the algorithms of action for various series of refrigerators LG, explain the operation of the function Super Freeze and answer the question whether the device can be used exclusively as a refrigerator. Electronic control allows you to flexibly configure parameters, but requires a careful approach to the settings.
Before you begin to manipulate the control panel, you must clearly understand the difference between “shutdown” and “increase in temperature”. If your goal is defrosting or long-term storage of vegetables that are afraid of freezing, you will need to not just turn off the freezer, but set the maximum possible temperature in this compartment. Inverter compressor, often installed in these models, responds to changes in settings smoothly, which ensures energy efficiency.
Features designs of two-chamber refrigerators LG
The equipment of the Korean brand LG is based on advanced cooling technologies, the system Total No Frostis popular. In such devices, the evaporator is often located alone (in the freezer), and cold air is distributed across both compartments using fans and dampers. This means that physically shutting down the freezer without stopping the entire cooling system is impossible without interfering with the design, which is strictly prohibited.
In models with separate cooling circuits (Twin Cooling) the situation is slightly different, but even there the control occurs through a single electronic board. When you try to “turn off” the freezer, you are actually instructing the controller not to maintain a low temperature in this volume. Thermal sensorslocated inside the chambers continue to monitor the situation, and if the temperature drops below a critical level due to cold from the adjacent compartment, the system can adjust the operation of the fans.
⚠️ Attention: Attempts to independently cut the wires leading to the evaporator heating element or the freezer fan will lead to loss of warranty and possible failure of the main control controller.
It is important for users to know that even when setting the maximum temperature in the freezer compartment, it will still be colder there than in the room. This is due to thermal insulation and possible cold flow through the common partition. Therefore, using the freezer as a regular shelf for storing jars of jam at room temperature will not work - the products may freeze against the walls.
Using the Super Freeze mode and temperature control
The closest analogue of "turning off" intensive freezing is exiting the mode Super Freeze. This function is designed to quickly freeze large quantities of fresh food. While it is active, the compressor runs non-stop, ignoring standard cycles. To stop this process, you must manually deactivate the function on the control panel.
To control the temperature in modern models with a display on the door, the following sequence of actions is used. First, press the Freezer or Tempbutton to select the adjustable zone. Then, using the arrow buttons + and -, set the temperature value. To minimize the operation of the freezer, you should set the maximum value, usually -6°C or -9°C, depending on the specific modification LG.
If your model does not have a digital display, you need to focus on the indicators. Often, the maximum temperature in the freezer is indicated by a flashing segment or the smallest number of points on the scale. Operating algorithm The electronics are designed so that when a given threshold is reached, the compressor will turn off, but the fan can continue to circulate air to equalize the temperature background throughout the entire volume of the refrigerator.
Instructions: how to set the maximum temperature in the freezer
The setting process may vary depending on the series of your refrigerator. Below are universal instructions for models with an external display. First, make sure that the doors are tightly closed, as if the door is open, the settings may be blocked or reset.
☑️ Temperature setting algorithm
After setting the parameters, the system will switch to a new operating mode in a few minutes. Inverter motor will begin to reduce speed or go into standby mode if the current temperature in the chamber has already reached the set maximum. It is important to note that a sudden change in settings does not lead to an immediate change in the climate inside - thermal stabilization takes time.
In some models with the function Eco Friendly or "Holiday Mode", you can automatically set the energy-saving mode. Although this mode is primarily focused on the refrigerator compartment (maintaining about +15°C there), it also affects the overall operating cycle of the compressor, reducing the frequency of its activation, which indirectly “turns off” active freezing.
| LG refrigerator model | Freezer temperature range | Type control | Mode feature |
|---|---|---|---|
| LG GA-B409 | -15°C... -23°C | Touch display | Requires button unlocking |
| LG GC-B459 | -18°C... -23°C | LED indicators | Adjustment with buttons on the end |
| LG DoorCooling+ | -6°C... -23°C | Sensor + Smartphone | Fine tuning possible via Wi-Fi |
| LG No Frost (classic) | -18°C (fixed) | Mechanical | Adjusting only the general thermostat |
Vacation mode and its effect on the freezer
Many users are looking for a way to turn off the freezer when leaving for a long time. For this purpose, refrigerators LG have a special mode, often called Holiday Mode or “Vacation”. Its activation can significantly reduce energy consumption, but its effect on the freezer compartment depends on the specific model.
In most cases, activating the "Vacation" mode increases the temperature in the refrigerator compartment to +15°C, preventing the appearance of mold and odor, but the freezer continues to operate in normal mode. This is done for safety: if you leave food in the freezer, it will not spoil. Complete shutdown of the freezer in this mode is usually not provided, since this contradicts the logic of long-term storage of supplies.
In vacation mode, the system can periodically turn on the fans to ventilate the refrigerator compartment, even if the compressor is not operating at full capacity. This prevents mustiness.
If your goal is to leave only the freezer on and turn off the refrigerator compartment, then the “Vacation” mode is ideal. If, on the contrary, you need to leave only the refrigerator, then it is difficult to do this using standard means. You will have to manually set the maximum temperature in the freezer, but, as mentioned earlier, this compartment will not become completely warm.
Control via the LG ThinQ application
Modern "smart" refrigerators LG support control via Wi-Fi and a mobile application LG ThinQ. This provides more customization options than physical buttons. Through your smartphone, you can not only change the temperature, but also track the history of the compressor.
Advanced settings are often available in the application, which may be hidden in the basic menu on the refrigerator itself. For example, you can activate the function Express Freeze for a certain time or, conversely, check whether any demo mode is activated, which simulates the operation of a refrigerator in a sales area. The remote control allows you to adjust settings without opening the door, which is especially useful for fine-tuning.
Use the Diagnostics feature in the LG ThinQ app to check if the temperature sensors are working correctly before attempting to change the settings manually.
It is worth considering that the refrigerator must be connected to your home Wi-Fi network for the app to work. If the connection is unstable, commands may not reach the device and the actual settings will not change. In such cases local control the buttons on the panel remain a more reliable method.
Possible problems and solutions during setup
When trying to change the temperature, users may encounter a situation where the values on the display flash or do not change. Most often this means that it is enabled child lock. To disable it, you usually need to hold down a combination of buttons (for example, Ice Plus and Temperature) for 3-5 seconds until a signal sounds.
Another common problem is discrepancies in sensor readings. If you set it to -6°C and the food freezes, the evaporator sensor may be faulty or the air duct damper is not closing completely. In models No Frost the damper regulates the flow of cold air from the freezer to the refrigerator compartment, and its jamming in the open position will lead to overcooling of both compartments.
⚠️ Attention: If, after changing the settings, the refrigerator makes unusual sounds (rumble, whistle) or does not return to mode within 24 hours, you must contact a service center. Self-repair of the cooling system is prohibited.
It is also worth remembering the seasonal factor. In the summer, when the ambient temperature in the kitchen is high, it is more difficult for the refrigerator to achieve the set parameters, and it may work more intensely. In winter, if the refrigerator is located against a cold wall or on an unheated loggia (which is not recommended for most models LG), the compressor may not turn on at all if the temperature in the chamber is higher than the set one.
Stable operation of the refrigerator depends not only on the panel settings, but also on operating conditions: distance to the walls, room temperature and product loading density.
Frequently asked questions (FAQ)
Is it possible to completely turn off the freezer while leaving the refrigerator running?
No using standard means. The design of LG two-chamber refrigerators, especially with the No Frost system, implies the joint operation of circuits or the presence of a common evaporator. You can only increase the temperature in the freezer to the maximum (about -6°C...-9°C), but completely turning off the cold in this compartment, leaving it as a freezer by name, will not work without the risk of damage to the compressor.
Why does not the temperature on the display change after pressing the buttons?
Most likely, the control panel lock is activated (Child Lock). Find the lock icon or corresponding button combination on the panel (often this is holding the "Freezer" button or the special "Lock" button for 3 seconds). Also check if the door is open - many models block changing settings when the door is open.
Is it harmful for a compressor to frequently change the temperature in the freezer?
For modern inverter compressors LG a smooth change in load is not critical. However, sudden changes in settings (for example, from -23°C immediately to -6°C and back) force the system to rebuild its operating algorithms, which can temporarily increase energy consumption. It is recommended to set the optimal mode and not change it unnecessarily.
What to do if ice still melts in a switched-off freezer?
If by “off” we mean setting the maximum temperature, then ice melting is only possible if the temperature rises above 0°C, which is unlikely in a running refrigerator. If you physically unplug the refrigerator, then melting is a natural process. If the refrigerator is working, but the freezer is warmer than (set), there may be a freon leak or a sensor malfunction.
