Leaving for a long period is always a concern for owners of modern household appliances, especially when it comes to the refrigerator. Many owners are wondering whether it is worth turning off the device completely or whether it is possible to leave it working as usual. It is for such situations that engineers LG Electronics have developed a special operating algorithm, called Vacation mode. This function allows you to significantly reduce energy consumption, while maintaining the necessary conditions inside the cameras.
The main idea of this option is to create an optimal balance between saving electricity and preventing damage to the device itself. If you simply turn off the refrigerator, an unpleasant moldy smell may appear inside due to the lack of air circulation and residual moisture. If you leave the standard mode, then electricity will be wasted on cooling empty shelves. The Vacation mode maintains the temperature in the refrigerator compartment at +15°C, which prevents the appearance of bacteria and odors, but does not waste resources on deep freezing.
Owners of smart models with support Smart ThinQ can control this parameter remotely, which adds an additional level of comfort. However, even on classic models with mechanical or electronic control, activating this function is not difficult if you know the sequence of actions. In this article we will analyze in detail all the nuances of the system's operation, consider the differences between models with Total No Frost and drip systems, and also answer the most frequently asked questions from users.
Principle of operation and technical features of the mode
Mode functionality Vacation (often referred to as “Vacation” or suitcase icon) is based on changing temperature targets for different zones of the refrigerator. Unlike the standard mode, where the system strives to maintain +3...+5°C, the vacation algorithm allows for an increase in degree. This is possible due to the fact that in the absence of food, the heat capacity of the internal space drops, and sudden temperature changes when opening the door are excluded.
In refrigerators LG with a system Multi Air Flow or Door Cooling+ fans continue to operate, but with less intensity or intermittent mode. This ensures constant air circulation, which is critical to preventing stagnation. The compressor is turned on rarely, only to maintain a given threshold of +15°C, which provides the main savings in resources. In this case, the freezer can operate in normal mode or also switch to economy mode, depending on the specific model and settings.
⚠️ Attention: Vacation mode is not intended for long-term storage of perishable products. At a temperature of +15°C, milk, meat and ready meals will spoil in a few hours.
It is important to understand the difference between models with different types of defrosting. In devices No Frost the risk of condensation is minimal, so raising the temperature is safe. In models with a drip system (Drop Defrost), moisture on the rear wall may evaporate more slowly at elevated temperatures, but the algorithm takes this factor into account when regulating the operation of the evaporator heating elements. Electronics LG independently adapts the compressor operating cycles to avoid freezing of the channels or, conversely, excessive heating.
Technical details of the compressor operation in vacation mode
In Vacation mode, the Linear Cooling inverter compressor operates at minimum speed, making short starts to maintain the temperature. This reduces wear on mechanical parts and noise levels to an almost inaudible level, which is especially important for studio apartments.
Step-by-step instructions: how to activate the function
The process of enabling the Vacation mode may vary slightly depending on the generation of your model LG and the type of control panel. On modern models with a door display or touch control panel, actions are performed through the settings menu. On simpler models, you may need to hold certain buttons for a long time. Below is a universal sequence that is suitable for most current series.
First you need to make sure that the refrigerator is connected to the network and is in working condition. If the temperature indicators are on, the system is ready for setup. You need to find a button labeled F/R (Freezer/Refrigerator) or a separate button Mode. In some interfaces you need to press a button Settings or the gear icon. After entering the menu, select the suitcase icon or inscription Vacation.
☑️ Algorithm for activating the Vacation mode
For models without a display, where control is carried out by LED indicators, activation is often accomplished by a combination of buttons. For example, simultaneously pressing the temperature control buttons for the refrigerator and freezer compartments for 5 seconds. After successful activation, you will hear a characteristic squeak, and the indicators may flash or change color. If you have a model with support Wi-Fi, the easiest way is to use the application LG ThinQ on your smartphone, where the function is activated with one touch in the “Control” section.
After turning on the mode, the refrigerator does not switch to it instantly. The system takes time, usually from 30 minutes to 2 hours, to smoothly raise the temperature in the chamber to the target +15°C. During this period, the compressor may work more actively than usual, reconfiguring thermal conditions. Don’t be alarmed if in the first hours you notice a change in engine operation - this is a standard calibration procedure.
Energy savings: real numbers and facts
One of the main arguments in favor of using the mode Vacation is a significant reduction in energy bills. The consumption of the refrigerator directly depends on the difference in temperature inside the chamber and in the room, as well as on the frequency of the compressor. When switching to holiday mode, energy consumption can be reduced by 30–50% compared to standard operation of an empty refrigerator.
Consider an approximate consumption table for a typical two-chamber refrigerator LG with a volume of 300 liters under various usage scenarios for 14 days (standard holiday):
| Reim work | Average consumption per day (kW/h) | Consumption for 14 days (kW/h) | Savings relative to standard |
|---|---|---|---|
| Standard (empty) | 1.2 | 16.8 | 0% |
| Mode Vacation | 0.5 | 7.0 | ~58% |
| Full shutdown | 0.0 | 0.0 | 100% |
| Standard (loaded) | 0.9 | 12.6 | - |
As can be seen from the data, complete shutdown provides maximum savings, but carries risks, which we will discuss below. Mode Vacation occupies the golden mean, allowing you to save significant money while maintaining the technical serviceability of the unit. For inverter models LG savings can be even higher, since their compressors are able to operate at ultra-low powers, consuming a minimum of energy to maintain a stable climate.
It’s worth Please note that actual figures depend on the room temperature. If the kitchen is located on the sunny side and it is hot there in the summer, the compressor will have to work more often, even in holiday mode. However, even in such conditions, the algorithm Smart Inverter optimizes the cycles, preventing the system from idling. This makes the function useful not only for the owner’s wallet, but also for the environment as a whole.
Why can’t you just turn off the refrigerator?
Many users mistakenly believe that the best way to save money is to completely turn off the appliance before leaving. However, engineers LG and service centers categorically do not recommend doing this unless absolutely necessary, especially if the absence lasts less than a month. The main reason lies in the properties of materials and biological processes that do not stop when the power is turned off.
Inside the refrigerator, even the cleanest, there remain microscopic food particles, grease in the seals and moisture in hard-to-reach places. When the compressor is turned off, the temperature becomes equal to room temperature, creating an ideal environment for the growth of mold and bacteria. When left idle for a long time without air circulation, sealing rubber bands can “suffocate” and become covered with a black coating, which is then extremely difficult to clean. The musty smell can be absorbed into the plastic panels and last for months.
⚠️ Attention: If you do decide to completely turn off the refrigerator, be sure to leave the doors ajar 2-3 cm. This will provide ventilation and prevent mold, but will require protection from dust and pets.
In addition, modern refrigerators LG are equipped with sophisticated electronics. Sudden voltage surges when turned on after a long period of inactivity can be stressful for capacitors and control chips. The mode Vacation keeps electronic components in good shape, allowing the self-diagnosis system to work in the background. Lubricant is also preserved in the compressor, which, during long periods of inactivity, can drain into the crankcase, causing oil starvation during the first start.
Another aspect is the preservation of the refrigerant in the system. The circulation of the refrigerant, although slow, prevents the separation of oil and freon. When turning on a “cold” device, water hammer may occur in the compressor if the oil is not distributed evenly throughout the system. Therefore, for vacations lasting up to 30 days, the mode Vacation is a technically more competent solution than complete conservation.
Nuances for models with Ice Maker and dispensers
Owners of premium refrigerators LG with automatic ice makers and water dispensers should take special care when preparing for vacation. The presence of water mains inside the building makes its own adjustments in preparation for a long absence. The water in the tubes and filters, when circulation stops, can become a source of an unpleasant odor or even a leak in the event of pressure changes in the water supply.
Before activating the mode Vacation on models with Ice Plus or Craft Ice it is recommended to perform a cleaning cycle or just drain off the accumulated ice. If your model allows it, turn off the water supply valve at the refrigerator inlet. This will protect the system from water hammer while you are away from home. Some advanced models LG have the function of automatically draining water from the lines when switching to vacation mode, but you should not rely on this completely.
Ice left in the bunker will eventually begin to melt and evaporate, increasing the humidity inside the chamber, which is contrary to the goal of saving. It is best to empty the ice container completely. If your model has a water filter, make sure that it does not require replacement right before leaving, as the old filter can become a source of secondary contamination of the water that remains in the system.
Returning from vacation: correct operation
When you return home, do not rush to immediately load the refrigerator with food. First you need to deactivate the mode Vacation. To do this, repeat the steps that you performed when you turned it on: press the mode button or select the appropriate item in the menu LG ThinQ. After disabling the function, the refrigerator will begin to intensively cool the chambers to operating temperatures. This process can take from 2 to 4 hours depending on the current room temperature.
Food should be loaded gradually. If you put a lot of warm food into the refrigerator at once, the compressor will work overload, trying to cool the large volume. Let the appliance run for an hour, then start filling the shelves. Check the operation of the ice maker, if there is one - the first portions of ice may have a foreign taste, it is better to throw them away.
Be sure to check the condition of the seals and inner walls. If during your absence there were power surges or other emergency situations, the refrigerator could report this (if connected to the network). A visual inspection will help make sure that ice or condensation has not formed inside, which could indicate a malfunction of the drainage system.
What to do if after a vacation the refrigerator does not freeze for a long time?
If, after exiting the Vacation mode, the temperature does not decrease within 5-6 hours, check whether the doors are tightly closed and whether the ventilation holes are clogged with food. Also make sure that the refrigerator is level and at least 10 cm from the wall.
Frequently asked questions (FAQ)
Is it possible to store vegetables in Vacation mode?
No, absolutely not. Temperatures of +15°C are too high for most vegetables and fruits. They will begin to wither, rot or sprout. The mode is intended only for an empty refrigerator.
How long does it take the refrigerator to come out of holiday mode?
Usually the process of returning to normal temperature (+3...+5°C) takes about 2-3 hours. Complete stabilization of climate and humidity occurs within 24 hours.
Is it harmful to frequently turn on and off the Vacation mode?
No, the electronics LG are designed for many switching cycles. However, it is not recommended to change the mode more than once every few days, so as not to create unnecessary load on the compressor.
Does Vacation mode work if there is a power outage?
If there is a power outage, the mode is reset. After power is restored, most models LG return to the last user settings, but it is better to check the status of the function manually.
Do you need to defrost the refrigerator before turning on Vacation mode?
If you have model No Frost, defrosting is not required. For a drip system, it is recommended to defrost and dry clean if before this the refrigerator was operating in normal mode.
