Leaving home for a long time often becomes a cause for concern for owners of modern household appliances. A reasonable question arises: is it worth leaving the refrigerator operating in standard mode if the freezer compartment is almost empty and the shelves in the main compartment are empty? It is for such situations that engineers LG have developed a special operating algorithm, known as “Vacation Mode” or Vacation.
This function not only reduces energy consumption, but also solves a number of technical problems associated with equipment downtime. Vacation mode transfers the refrigeration unit to a state of minimal energy consumption, while maintaining the functionality of critical components. This allows you to avoid the appearance of a musty smell, the formation of mold and excess icing, which are inevitable when the appliance is completely disconnected from the network for a long period of time.
In this article we will analyze in detail the principle of operation of this option, consider the differences in control for different series of refrigerators LG and answer questions that concern users before the trip. Understanding how this function works will help extend the life of your device and avoid unpleasant surprises upon return.
The principle of operation and purpose of the Vacation function
The main task of the “Vacation” mode is to optimize the operation of the compressor and defrost system in the absence of active loading of products. In normal mode, the refrigerator LG maintains the temperature in the refrigerator compartment at +3...+5°C, and in the freezer - about -18...-24°C. When activated Vacation Mode the temperature in the main compartment rises to +15°C.
This temperature is a threshold: it is high enough for the compressor to turn on extremely rarely, saving electricity, but low enough to prevent the growth of bacteria and the appearance of an unpleasant odor inside the cabinet. In the freezer, the temperature usually remains at the same level or increases slightly, which allows you to preserve food if you do not plan to defrost this compartment completely.
An important feature is the operation of the system No Frost. Even in vacation mode, defrost fans and heating elements continue to function according to the specified algorithm, preventing ice from fouling the evaporator. If you simply unplug your refrigerator, the residual moisture becomes an ideal incubator for mold. Vacation mode prevents this process by keeping the internal environment dry and ventilated.
⚠️ Attention: Do not confuse Vacation mode with a complete power outage. If you plan not to use the refrigerator for more than 2-3 months, it is better to completely defrost it, wash it, dry it and leave the doors ajar. Long-term operation of the compressor without load is also not recommended by manufacturers.
How to activate the holiday mode on different LG models
The refrigerator control interface LG has changed over the years, so the algorithm for activating the function may differ depending on the series of your device. In most modern models with a display on the door, you need to press the button Mode or F+ (Function) several times until the suitcase icon or inscription lights up on the indicator Vacation.
For models with touch controls on the door (series DoorCooling+ or InstaView) the process may look different. Often you need to press and hold a button Freezer or a special key combination for 3-5 seconds. In some cases, access to the function is hidden in the settings menu, which can be accessed by long pressing the button Settings or Menu.
- 🧊 Classic models: Press the button
Modeuntil the suitcase icon appears on the freezer display. - 📱 Models with Wi-Fi (ThinQ): Activation is possible through the application on a smartphone in the “Power management” or “Operating modes” section.
- 🔘 Touch panels: Use the combination
Freezer+Alarm(hold for 3 seconds) to enter the mode selection menu.
After activation, you can hear a characteristic click - this switches the compressor operating mode. The display may go dark after a while to save power, but the selected mode will be saved in the controller's memory. If you are not sure about your model, refer to the instructions, as the location of the buttons may vary.
Energy consumption and saving resources
Using the Vacation mode can significantly reduce energy consumption. In standard mode, the refrigerator consumes energy to maintain a low temperature and operate the fans. When switching to “vacation”, the load on the compressor is reduced by 60-70%, since the temperature difference between the internal volume of the chamber and the environment is minimal.
However, it is worth understanding that the savings will not be colossal when compared with completely turning off the device. Energy efficiency in this context, this is a compromise between the desire to save money and the need to keep the equipment in working condition. The refrigerator continues to consume current to operate the electronics, the backlight (if it is not turned off) and periodically start the compressor.
For clarity, let's look at comparative energy consumption data for a conventional refrigerator model LG with a volume of 300 liters:
| Operating mode | Average consumption (kW/day) | Monthly consumption (kW) | Compressor status |
|---|---|---|---|
| Standard (50% load) | 1.2 - 1.5 | 36 - 45 | Works cyclically |
| Vacation (Vacation) | 0.4 - 0.6 | 12 - 18 | Rare switching on |
| Empty (no mode) | 0.9 - 1.1 | 27 - 33 | Frequent switching on |
| Complete shutdown | 0 | 0 | Does not work |
As can be seen from the table, using a special mode saves more than 60% of energy compared to normal operation of an empty refrigerator. This is especially true for long trips of two weeks or more.
Impact on the ice maker and the No Frost system
One of the key functions of the Vacation mode in refrigerators LG is the automatic control of the ice maker. If your model has Ice Plus or automatic ice making, the water supply to the ice maker is blocked when you enter vacation mode.
This is a critical point. If left idle for a long time, the water in the pipes and valves may stagnate, which will lead to an unpleasant taste or even the proliferation of microorganisms. Moreover, if the ice maker continues to operate without the user collecting ice, the hopper will overflow and the mechanism may jam or fail.
The system No Frost also adapts. The frequency of defrost cycles increases as the humidity inside the chamber drops due to the lack of food (which contains water) and the infrequent opening of the door. This prevents the air from drying out, but ensures that the drainage system does not freeze.
⚠️ Attention: In some older models, the Vacation mode does not automatically turn off the water supply. Before leaving, it is recommended to manually close the water supply valve at the entrance to the refrigerator to avoid leaks in the event of a pressure surge in the water supply.
What happens if you forget to turn off the ice maker?
If the ice maker continues to operate in holiday mode, the bin will fill and new portions of ice will be added. will begin to spill out onto the floor of the refrigerator compartment or get stuck in the mechanism, causing the gears to break during the next cycle.
Protection against mold and odors during downtime
The main enemy of an empty refrigerator is stagnant air and residual moisture. Even after thorough cleaning, microscopic particles of organic matter remain in corners, on seals and in hidden cavities. When turned off and the door closed, an ideal environment is created for the development of fungal spores.
Vacation mode prevents this scenario by maintaining the temperature background above the dew point, but below what is comfortable for bacteria. Air circulation, although slow, continues. This prevents moisture from condensing on the walls and turning into mold.
- 🌿 Ventilation: The fan turns on periodically, refreshing the air inside the chamber.
- 💧 Humidity control: Heating the evaporator during rare defrost cycles dries out the drainage system.
- 🦠 Bacteriostatic effect: Temperature +15°C inhibits the proliferation of most types of bacteria that cause rotting.
However, before activating the mode, it is recommended to carry out preventive cleaning. Wipe the shelves and walls with a weak soda solution or a special refrigerator cleaner. A clean surface in combination with the Vacation mode guarantees the absence of odors after your return.
☑️ Preparing the refrigerator for the Vacation mode
Returning to normal operation
After returning from vacation, it is necessary to correctly remove the refrigerator from the energy-saving mode. Simply opening the door and putting in food is not enough - the unit requires time to stabilize the temperature parameters. Deactivation of the Vacation mode usually occurs automatically when the door is opened or any button is pressed, or manually by repeatedly cyclically switching the button Mode.
After turning off the Vacation mode, the refrigerator LG will begin to work in enhanced mode to cool the internal volume to the set values. This process can take from 2 to 6 hours depending on the room temperature and current load. It is not recommended to immediately load the chamber with products in large quantities.
Let the equipment run “idle” for at least 30-60 minutes after exiting the vacation mode. This will allow the compressor to reach its operating rhythm, and the No Frost system to stabilize the humidity. Only after this can you start filling the shelves with products.
⚠️ Attention: Interfaces and names of functions may differ depending on the software version of your refrigerator. If you do not find the described function, check the current instructions on the manufacturer's official website for your specific model.
Often asked questions (FAQ)
Is it possible to store food in the refrigerator compartment in Vacation mode?
Absolutely not. The temperature in the main compartment rises to +15°C, which is a dangerous zone for storing perishable food. In this mode, you can only store closed canned food, drinks or dry foods that do not require cold.
How much energy does an LG refrigerator consume in vacation mode?
Consumption depends on the volume of the chamber and the ambient temperature, but on average it is 0.4–0.6 kW per day. This is about 2-3 times less than during standard operation with a load.
What to do if the refrigerator does not freeze well after the Vacation mode?
Let the device operate without loading in standard mode for 5-6 hours. If the temperature does not stabilize, check if the air duct dampers are stuck and make sure that the refrigerator is level.
Do you need to defrost the refrigerator before turning on the Vacation mode?
No, the No Frost system works automatically. However, if you notice frost on the door or products before turning on the mode, it is better to defrost to avoid unnecessary defrosting cycles in your absence.
Is it possible to turn on the Vacation mode remotely via Wi-Fi?
Yes, if your model supports the technology LG ThinQ. Through the application on your smartphone, you can activate this mode from anywhere in the world, provided that the refrigerator is connected to your home Wi-Fi network.
