A long absence from home always causes concern for the condition of household appliances, especially when it comes to refrigeration equipment. Many apartment owners mistakenly believe that before leaving it is necessary to completely disconnect the unit from the network, defrost it and leave the doors open.
However, modern manufacturers of household appliances have provided a more rational solution - a special one. vacation mode. This function allows you to maintain the functionality of the equipment and prevent the appearance of unpleasant odors while you are away from home.
In this article we will examine in detail the principle of operation of this option, its difference from the normal mode and find out why completely turning off the power can cause more harm than good.
The main purpose of the saving function energy
The main task of the mode, which is often marked with a palm tree or suitcase icon, is to maintain the minimum required temperature with minimal power consumption. When you leave for a long period of time, there is no food left in the chamber, so intensive cooling to standard -18°C or +4°C becomes pointless.
In this state, the compressor turns on extremely rarely, only to ensure that the temperature in the chambers does not fall below a critical threshold, usually around +15°C. This approach allows refrigerator not to waste resources on freezing empty space, but also prevents the temperature from becoming equal to room temperature.
If the equipment operated in normal mode without food, it would perform unnecessary on and off cycles, wearing out the life of the motor. A special program optimizes these processes by putting the unit into a “sleep” state.
It is important to understand that this function is not intended for storing food. At a temperature of +15°C, any perishable goods will spoil in a matter of hours.
⚠️ Attention: Before activating the mode, be sure to make sure that all shelves and drawers are completely empty. Having food at high temperatures will lead to spoilage and bacterial growth.
Electricity savings when using this option can reach significant values, especially if the vacation lasts two weeks or more. This becomes especially relevant in the context of constantly rising energy tariffs.
Principle of operation and temperature parameters
The mechanism of action of this function is quite simple, but effective. When switching to mode Vacation or Eco (the name may differ depending on the brand), the electronics changes the thermostat setting.
In the refrigerator compartment, the temperature rises to the level +15...+17°C. This value was not chosen by chance: it is high enough so as not to waste energy on cooling, but also low enough to prevent the development of mold and the appearance of a musty smell, which will inevitably occur at a room temperature of +22...+25°C.
In the freezer the situation depends on the type of defrosting system. In models with No Frost temperature can be maintained at -6...-10°C, which is enough to preserve the structure of plastic and rubber seals, but not enough for storing meat.
Some advanced models, such as Liebherr or Boschcan completely turn off cooling refrigerator compartment, leaving only air circulation active for ventilation. This prevents stagnation of air masses.
The key point is that ventilation does not stop completely. Periodic short turns on the fans provide air exchange, which is critical to preventing condensation.
Why you can’t just turn off the refrigerator
There is a common myth that any electrical appliance that is not in use should be unplugged. In the case of refrigeration equipment, a long stop of the compressor can lead to serious technical problems.
The first and main danger is drying out of the lubricant in the compressor and rubber seals. The oil in the system must constantly circulate or at least be in contact with the refrigerant. During prolonged inactivity, it can thicken or drain into the crankcase, which will lead to the compressor running dry the next time it is started.
The second problem concerns the rubber seals on the doors. Without changes in temperature and humidity, rubber can lose elasticity, crack or deform. As a result, after returning from vacation, you may find that the door no longer fits tightly.
What will happen to the compressor after a year of inactivity?
During a long shutdown (more than 3-4 months), the oil in the compressor may separate or thicken. When turned on abruptly, there is a high probability of water hammer or jamming of the piston group, which will require expensive repairs.
In addition, a completely defrosted and switched off unit becomes an ideal environment for the proliferation of microorganisms. Even a thorough washing before turning it off does not guarantee that mold spores will not penetrate into the hard-to-reach channels of the ventilation system.
That is why manufacturers recommend not interrupting the power supply completely, but using gentle operating modes.
⚠️ Attention: If you decide to completely turn off the equipment for a period of more than a month, be sure to leave the doors ajar. A closed, damp chamber will turn into an incubator for mold in a few weeks.
Instructions for activating the mode
The process of switching household appliances to energy saving mode may differ depending on the manufacturer and type of control (mechanical or electronic).
For models with an electronic display, you usually need to press and hold a certain combination of buttons. Often this is a button with a picture of a snowflake or a vacation icon. In some models Samsung or LG it is necessary to simultaneously press the temperature control buttons in the refrigerator and freezer compartments for 3 seconds.
In mechanical models, where control is carried out by a rotary regulator, it is enough to unscrew the thermostat knob to position Min or Off (if there is a separate mode for the freezer). However, in older models without the No Frost system, this may require manual defrosting before leaving.
Below is a table with examples of activating the function on popular brands:
| Brand | Designation on the panel | Activation method | Temperature in HK |
|---|---|---|---|
| Samsung | Suitcase icon / Eco | Hold Eco button for 3 sec | +15°C |
| Bosch | Vacation | Vacation button | +14°C |
| LG | Eco / Palm | Eco button | +15°C |
| Indesit | Absent (Minimum) | Knob 1 | +10...+12°C |
After activation, the corresponding indicator may light up on the display. In some models, for example Electrolux, the screen may go dark to save energy, responding only to button presses.
☑️ Preparing for departure
Nuances of working with the freezer camera
The issue of maintaining the operation of the freezer deserves special attention. In vacation mode, the freezer often continues to operate, but in a light mode.
If your goal is to preserve frozen foods (meat, berries, semi-finished products) during the holidays, then the standard mode Vacation may not be effective enough, since the temperature may rise above the safe -12°C. In this case, it is better to leave the normal operating mode, having previously loaded the chamber as much as possible with food or bottles of water.
An empty freezer in economy mode will maintain a temperature of about -6...-10°C. This is safe for the unit itself, but unsuitable for storage most frozen goods.
There is also a “Super Freeze” function, which is sometimes confused with vacation. You cannot turn it on before leaving, as it forces the compressor to work continuously, which will lead to wasted energy.
In two-compressor models, you can control the cameras independently. This is an ideal option: the refrigerator compartment is switched to economy mode, and the freezer is left to operate normally if there are stocks left.
Return to normal operation
After returning from vacation, you should not immediately load the refrigerator with food. The unit takes time to reach operating mode and stabilize the temperature.
First you need to deactivate the holiday mode. To do this, you usually just need to press the same button as to turn it on, or simply open the door (in some models, this wakes the device from sleep mode). After this, the equipment will begin cooling.
It is recommended to wait 2-3 hours before loading products. If you put warm food in a chamber that has not yet cooled down, the compressor will work with overload, trying to cool a large volume, which will shorten its service life.
It is also recommended to wipe the shelves with a damp cloth before loading, since dust may have settled on them during inactivity, even if the doors were closed.
⚠️ Attention: Technical characteristics and control interfaces may vary depending on the specific model and year of manufacture. Always check the official user manual for your device.
Following these simple rules will extend the life of your equipment and keep it in working order after a long absence.
Is it possible to turn on the vacation mode if there is food left in the refrigerator?
Strongly not recommended. A temperature of +15°C will lead to rapid spoilage of dairy, meat products and vegetables. The mode is intended only for an empty unit.
How much electricity does this mode save?
Consumption is reduced by approximately 30-40% compared to the normal operating mode of an empty refrigerator, since the compressor turns on much less frequently.
What to do if my model does not have one functions?
If there is no special mode, set the thermostat to the minimum value (number 1), wash the chamber thoroughly and leave the refrigerator on. It is not advisable to turn it off completely.
Is rare switching on in holiday mode harmful for the compressor?
No, modern compressors and control systems are designed for such cycles. Rare inclusions are even more useful than constant operation without load, as they reduce the overall wear and tear of mechanical parts.
