Refrigerator owners LG often wonder whether it is possible to isolate the operation of the freezer chambers, leaving the refrigeration compartment active. This need arises when moving, long-term absence or the need to convert equipment for storing vegetables. Unlike older models, modern two-compressor systems allow you to control zones independently, but require a careful approach.
Before starting manipulations, it is important to understand that completely physically turning off the power to the freezer without turning off the entire unit is impossible at the software level in most household models. However, there are effective methods minimizing energy consumption and stopping the cooling cycle. We will look at standard settings and technical nuances that will help solve the problem.
Analysis of temperature control capabilities in different models
The first thing to start with is determining the type cooling systems of your device. Models with one compressor, even if they are equipped with a No Frostsystem, are physically unable to cool the refrigeration chamber without freezing the second part of the circuit. In such units, the refrigerant circulates in a single circle, and only one part can be “turned off” only by mechanically blocking the channels, which is not recommended to be done without skills.
The situation changes dramatically if you have two-compressor refrigerator LG. In such devices, for example, in series GC-B or GA-B with a double circuit, each compartment has its own independent motor. This allows you to theoretically control them separately, although the standard control panel often blocks the complete shutdown of the freezer, leaving the minimum operating mode to prevent damage to the compressor.
It is also important to take into account the age of the equipment. In new models, temperature control is carried out with high precision. Attempts to tamper with the electronics may result in an error in the control code. Therefore, always check the instructions for the specific series, since the operation logic inverter compressor Linear Inverter temperature control is carried out with high precision. Attempts to tamper with the electronics may result in an error in the control code. Therefore, always check the instructions for the specific series, since the operating logic Smart Diagnosis may regard the lack of load as a malfunction.
⚠️ Attention: Do not try to programmatically set the temperature in the freezer above 0°C if the model does not explicitly support this. This can lead to constant operation of the fans and freezing of the air ducts.
Using the "Holiday" mode to stop the freezer
The safest and most common way to reduce the activity of the freezer is to use the function "Vacation" (Holiday Mode). This mode is designed specifically for situations when the refrigerator is not used for a long time, but you need to keep food fresh or simply save energy. Activation occurs through the control panel on the door.
To turn it on, you need to find the button with the corresponding icon or enter the menu via Smart Management. In some models LG you need to hold the button Ice Plus or combination Fridge + Freezer for 3 seconds. After activation, the temperature in the refrigerator compartment rises to +15°C, and the freezer goes into minimum consumption mode or turns off, depending on the specific firmware modification.
☑️ Activating the vacation mode
It is worth noting that in the "Vacation" mode air circulation inside the freezer stops, allowing it to gradually defrost naturally if the door is closed. This is an ideal option for preserving equipment during the holidays, as it prevents the appearance of mold and unpleasant odors due to the absence of active fan operation.
The nuances of the operation of inverter models
In refrigerators with a linear inverter, the vacation mode may not turn off the compressor completely, but only reduce its power to a minimum. This is normal behavior necessary to preserve the oil life in the compressor and prevent jamming of the piston group during prolonged inactivity.
Manual adjustment of temperature parameters through the panel
If the normal vacation mode does not give the desired result, you can try to manually change the temperature settings. The display LG usually shows two values. By pressing the Freezerbutton, you can try to set the maximum possible temperature, often denoted as -6°C or -3°C in some modifications, although the standard range usually starts from -15°C.
When the temperature rises to the maximum cooling cycle becomes less common. The compressor turns on only when the sensors detect a significant rise in heat. This allows you to significantly reduce energy consumption. However, remember that it will not be possible to completely stop cooling by software in single-compressor models - the system will strive to maintain a given, albeit high, negative threshold.
| Model / Series | Control type | Min. pace. freezers | Features |
|---|---|---|---|
| LG GA-B409 | Touch | -15°C (standard) | One compressor, complete shutdown is impossible |
| LG GC-B499 | Electronic | -6°C (max) | Holiday mode available |
| LG DoorCooling+ | Sensor + Wi-Fi | -18°C | Control via ThinQ app |
| LG Side-by-Side | Door display | -23°C...-6°C | Often there are two cooling circuits |
When setting parameters, follow the indication. If the Lockicon lights up on the screen, it means that the panel is locked from accidental clicks. To unlock, you usually need to hold the Lock or Child Lock button for 3-5 seconds. It will not be possible to change temperature mode without unlocking.
Technical methods: turning off the compressor and sensors
To radically solve the problem, when you need to completely stop the freezer, and software methods do not work, you have to resort to technical interventions. The most effective way is a physical shutdown freezer compressor (if there are two of them) or shutting off the refrigerant supply. In single-compressor models, this cannot be done without losing cold in the main compartment.
In dual-compressor systems, you can Locate (find) the second compressor, usually located in the lower rear part of the unit, and disconnect its power terminals. Before doing this, be sure to unplug the refrigerator! You can also turn off temperature sensor (thermistor) in the freezer. If you “deceive” the controller by showing it that the temperature has already been reached, it will stop starting the cooling cycle.
⚠️ Attention: Disconnecting the sensors or the compressor yourself will void your warranty. Incorrect intervention in the electrical circuit can lead to a short circuit or failure of the control board Main PCB.
There is also a method of mechanically closing the air duct damper, if the design of the model allows this. By blocking the flow of cold air from the evaporator into the freezer compartment, you will stop its cooling. However, this will require partial disassembly of the inner lining, which can cause damage to thermal insulation and plastic elements.
Rules for defrosting and preservation during downtime
If your goal is to preserve the refrigerator during moving or storage, simply turning off the freezer is not enough. Complete defrosting is necessary. Leave doors open for at least 24 hours after unplugging. The moisture accumulated in the system No Frostmust completely evaporate, otherwise mold will form inside.
After defrosting, wipe the internal surfaces with a weak solution of soda or a special product for cleaning refrigerators. Pay special attention to the door seals - they need to be washed and lubricated with silicone grease so that they do not dry out and lose during long periods of inactivity. tightness during prolonged downtime.
To store the refrigerator when it is turned off, it is better to lock the doors slightly open position Use cardboard spacers or special fasteners to secure air circulation inside the cameras. This will prevent mustiness and the formation of condensation.
⚠️ Attention: Never store the refrigerator when it is turned off with the doors tightly closed. Lack of ventilation leads to the rapid development of bacteria and corrosion of the metal parts of the evaporator.
Frequent errors and problems during setup
Users often encounter the fact that after trying to change the settings, the refrigerator begins to behave strangely. For example, an error Er FF (fan error) or Er SFmay appear. This happens if the system detects a discrepancy between the sensor readings and the actual temperature. In such cases, a complete resetting the settings (Reset) or short-term disconnection from the network helps.
Another common mistake is trying to turn off the freezer in a working refrigerator full of food. A sudden change in temperature or stopping air circulation can lead to spoilage of food in the main compartment due to an imbalance in temperature. Always empty the camera before making experimental settings.
Do not forget that modern refrigerators LG are equipped with complex electronics. Frequent mode switching or power surges during the setup process can damage control board. Use a voltage stabilizer if there are interruptions in your network.
Is it possible to completely turn off the freezer in a single-compressor refrigerator LG?
No, in single-compressor models it is physically impossible to turn off the freezer while leaving the refrigerator compartment running. The refrigerant circulates through a single circuit, and stopping cooling in one place will stop it everywhere. The only option is to use the "Vacation" mode to minimize operation, but not completely shut down.
What does a flashing temperature indicator mean after setting?
A flashing indicator usually indicates that the set temperature has not yet been reached or a system malfunction has occurred. If flashing continues for more than 2 hours after changing the settings, check that the doors are closed tightly and that air circulation is not obstructed. This may also be a sign of a sensor malfunction.
How to reset an LG refrigerator to factory settings?
To reset the settings, most often you need to hold the button Freezer and Ice Plus simultaneously for 5-7 seconds, or find a combination in the instructions for your specific model. In some cases, simply disconnecting the device from the power supply for 10-15 minutes helps.
Is frequent turning on and off of the freezer harmful to the compressor?
Yes, frequent start and stop cycles are harmful to the compressor, especially for conventional (non-inverter) models. The motor experiences peak loads when starting. Inverter compressors LG Linear Inverter are more resistant to such modes, but sudden changes are also harmful to them. It is recommended to avoid frequent changes in temperature conditions unless necessary.
