When going on a long trip or vacation, every owner of modern household appliances wonders about energy savings and food safety. Vacation mode (sometimes called "Holiday mode" or "Vacation mode") is a special function developed by engineers to optimize the operation of refrigeration equipment during periods when the owners are away from home for a long time.
The main essence of this mode is that the refrigerator compartment stops maintaining a low temperature, while the freezer compartment continues to operate normally. This can significantly reduce electricity consumption, prevent unpleasant odors and mold from appearing in the empty fresh food compartment, and also keep frozen supplies intact.
It is important to understand that simply unplugging the refrigerator is not always the best solution if you plan to return in a month or two. Correct use of the function Holiday mode guarantees that the equipment will remain in working condition, and the compressor will not fail due to stagnation of oil or moisture.
The principle of operation and purpose of the Holiday mode function
The function vacation in the refrigerator works on the principle of selective cooling. When you activate this mode, the unit's electronics shut off the flow of refrigerant to the refrigerator compartment's evaporator or stop the fan circulating cool air in that compartment. The temperature in the main compartment rises to ambient (room), usually 15–17 degrees Celsius.
At the same time freezer compartment continues to work, maintaining a temperature of -18 degrees and below. This is critical for maintaining supplies of meat, vegetables and processed foods. If the refrigerator were simply turned off, all the supplies in the freezer would melt in a day or two, creating the risk of food spoilage and bacterial growth.
Another important task of the regime is the fight against mold i unpleasant odors. In a warm but not hot room (15°C), mold spores will develop more slowly than if the compressor is completely stopped, when there may be high humidity inside. In addition, air circulation (even minimal) prevents the musty smell from being “preserved” inside the cabinet.
⚠️ Attention: The vacation mode is not intended for storing fresh food. If you leave milk, meat or vegetables in the refrigerator, they will spoil within a few hours, as the temperature there rises to room temperature.
Modern models, such as Liebherr, Bosch or LGmay have different algorithms for implementing this function. In some cases, the compressor operates in an economical cycle, turning on only occasionally to maintain minimal air movement, in others, the refrigeration chamber circuit is completely turned off.
Differences from regular power off
Many users mistakenly believe that to save energy it is enough to simply unplug the cord from the outlet. However, between complete shutdown and mode Holiday there is a significant technical difference that affects the service life of the unit.
When the refrigerator is completely turned off, the compressor oil flows into the crankcase, and the refrigerant is distributed unevenly throughout the system. When switched on again, a “hydraulic hammer” or oil wedge effect may occur, which is especially harmful for older models. The vacation mode keeps the system in good shape, allowing the oil to remain in motion and lubricate rubbing parts.
In addition, a completely turned off refrigerator in a hot room can become a breeding ground for microorganisms. The cabinet walls are heated to ambient temperature (30°C and above in summer), which creates ideal conditions for bacteria. The function Vacation keeps the temperature at 15°C, which is uncomfortable for the active reproduction of most types of pathogenic flora.
- 🔌 Energy consumption: in vacation mode, energy consumption is reduced by 40-60% compared to normal operation, while when turned off it is zero, but the advantages of preserving equipment are lost.
- ❄️ Temperature mode: When turned off, the temperature is compared with room temperature; in vacation mode, it is artificially maintained at +15°C.
- 🦠 Hygiene: a running fan (in No Frost models) or natural convection in vacation mode prevents air stagnation and the appearance of mustiness.
How to activate the vacation mode on different models
The process of activating the function depends on the brand and control interface of your equipment. In most modern models with electronic control (Samsung, LG, Beko), you need to hold down a certain combination of buttons on the control panel.
Usually the algorithm looks like this: you need to find a button with an icon of a suitcase, a palm tree or an inscription Holiday. Often you need to hold it for 3-5 seconds until the corresponding indicator appears on the display. In some models Indesit or Atlant it may be necessary to switch the temperature regulator to a special position, indicated by a snowflake symbol or the letter "H".
If you have a refrigerator with a mechanical control (one or two knobs inside the chamber), the release function may not be available. In such cases, manufacturers recommend simply setting the regulator to minimum cooling (number 1) or, in case of prolonged absence, completely defrosting and turning off the device.
☑️ Check before activating the mode
For smart refrigerators connected to Wi-Fi (for example, SmartThinQ from LG or SmartThings from Samsung), activation can be done remotely via an application on a smartphone. This is convenient if you have already left and remembered the refrigerator halfway to the airport.
| Brand | Designation | Action |
|---|---|---|
| Samsung | Suitcase icon | Hold 3 sec |
| Liebherr | Eco / Vacation button | Single press |
| Bosch/Siemens | Palm tree symbol | Press until signal |
| LG | Eco button | Hold for 3 seconds |
How long can the refrigerator be in vacation mode
Technically, modern compressors and control systems are designed for continuous operation for many years. The performance of the mode vacations is not limited by strict time frames. You can keep the refrigerator in this state for a month, two or even six months, if necessary.
However, it is worth taking into account the human factor and external conditions. If you're away for more than 3-4 months, there's a risk of power surges while you're away. A thunderstorm or an accident on the line can damage the electronics, even if the refrigerator is operating in economy mode.
⚠️ Attention: If you will be away from home for more than 2-3 months, it is strongly recommended to install a voltage stabilizer or completely de-energize the device, first defrosting and washing it.
The condition of the seals is also important. During long-term operation in holiday mode, the doors must be tightly closed. If you are leaving for a very long period, it is better to leave the doors slightly open (locking them), but then you cannot turn on the vacation mode - the refrigerator must be turned off.
What happens to the oil in the compressor during long periods of inactivity?
When operating for a long time in vacation mode (even economical), the oil continues to circulate through the system, lubricating the parts. This prevents the rubber seals from drying out and the piston group from jamming, which often happens when the compressor is turned off for a long time.
Preparing the refrigerator before a long absence
Turning on the mode Holiday is only part of the preparation. To avoid an unpleasant surprise upon your return, it is necessary to carry out a number of preparatory measures. First of all, the refrigerator compartment must be completely empty.
Remove all foods that can spoil: milk, sauces, open cans, vegetables and fruits. Even at +15°C they will begin to ferment or rot. Wipe the shelves and walls with a damp cloth and mild detergent to remove crumbs and food debris.
Pay special attention to the freezer compartment. Make sure that the food there is frozen well and tightly closed. If the freezer is not completely full, it makes sense to fill the free space with plastic water bottles. This will help the camera keep cold longer in case of a sudden power outage.
- 🧼 Cleanliness: Wash the internal surfaces thoroughly to eliminate sources of odor.
- 💧 Moisture: Check the drainage hole on the back wall - it should not be clogged, otherwise water will accumulate inside.
- 🚪 Doors: make sure that nothing (packaging, bag) interferes with the tight fit of the door.
After activating the mode, listen to the operation of the unit. It should run quieter than usual as the load on the system is reduced. If you hear loud clicking or buzzing noises, the feature may not have activated correctly.
Returning from vacation: post-trip actions
When you return home, the first thing you need to do is deactivate the mode holidays. This is usually done by pressing the same button or combination again that was used to turn it on. The indicator on the panel should go out.
Do not rush to immediately load the refrigerator with food. Let it work as usual for 2-3 hours so that the temperature in the chamber drops to the required +4°C. By loading warm food into a cabinet that has not yet cooled down, you will create additional load on the compressor.
Be sure to ventilate the refrigerator compartment. Despite the +15°C mode, the air inside could become stale. Wipe down the shelves again and check for condensation. If everything is in order, you can safely fill the supplies with fresh products.
Common mistakes and myths about the Vacation function
There are many misconceptions around the vacation regime. One of the most common myths is that in this mode the refrigerator does not consume energy at all. This is not true: the freezer continues to operate, consuming electricity, albeit in a smaller volume.
Another mistake is leaving food in the refrigerator “just in case.” Some users think that +15°C is cold enough to store sausage or cheese. In fact, this is the temperature of a cool cellar, but for modern products that require +2...+6°C, this is detrimental.
There is also an opinion that the holiday mode is harmful for the compressor, since it is “underloaded”. Engineering calculations show the opposite: working in a gentle mode with a smaller temperature difference (if) or with one circuit turned off extends the life of the unit compared to cycles of constant on-off at full power.
⚠️ Attention: Do not use the vacation mode to defrost the refrigerator! If you need to defrost the unit, it must be completely unplugged. Vacation mode keeps the compressor running, which prevents ice from melting.
Questions and answers (FAQ)
Is it possible to turn on the holiday mode if the freezer is empty?
Technically it is possible, but it does not make much economic sense, since an empty freezer also consumes less energy. However, if you want to keep your refrigerator in good shape and avoid odors, you can turn on the mode. Make sure the freezer door is tightly closed.
Will the refrigerator compartment be completely warm?
No, the temperature there will not be the same as room temperature (20-25°C). It will remain at 12-17°C. This is enough to prevent mold from growing, but not enough to store perishable food.
What should I do if my model does not have a "Vacation" button?
If there is no function, but you need to leave, set the temperature regulator to the minimum value (1 or Min). If the departure is long (more than 2 weeks), it is better to completely turn off the refrigerator, defrost it and leave the doors ajar.
Does vacation mode consume a lot of electricity?
Consumption is reduced significantly. The main energy consumer—cooling the refrigeration chamber—is turned off. Only the freezer works, whose consumption is approximately 30-40% of the total energy consumption of a two-chamber refrigerator.
