Before a long trip or business trip, every owner of modern household appliances has a logical question: what to do with the refrigerator? Leaving it turned on in normal mode is economically impractical and unsafe, and completely defrosting and disconnecting from the network is fraught with the appearance of an unpleasant odor and mold. It is for such situations that engineers have developed a special vacation mode (Vacation Mode), which allows you to maintain the minimum necessary operation of the unit without the risk of damage to internal surfaces.
Activation of this function puts the refrigerator compartment into an energy-saving state, raising the temperature to a safe level at which bacteria do not develop, but are not consumed excess electricity. At the same time, the freezer continues to operate as normal, keeping your supplies frozen. It is important to understandthat the operating algorithms can vary significantly depending on the brand and model of your device, be it Liebherr, Bosch or Indesit.
In this article we will analyze in detail how to properly prepare equipment for long-term downtime, what nuances exist among different manufacturers and what absolutely cannot be done if you want to find the device in working condition after returning. We will look not only at digital control panels, but also at mechanical controls, which also require specific settings before you are away.
What is vacation mode and why is it needed
Vacation mode is a special program for controlling the compressor and heat removal system, designed to minimize energy consumption during periods when no one is using the refrigerator compartment. In normal operation, the electronics strive to maintain a temperature of about +4°C, constantly turning the motor on and off. When you leave, the inside is empty, and there is no point in keeping it so cold, but a complete shutdown can lead to dampness.
When the function is activated Vacation Mode the temperature in the main compartment rises to +10...+15°C. This is a critical range: it is too high for most types of mold and mold-causing bacteria to grow, but low enough to prevent moisture from condensing on the walls. The compressor turns on extremely rarely, only to maintain this wide range, which significantly reduces electricity bills.
It is worth noting that this mode is not a complete analogue of shutdown. The freezer (if your model has one) continues to freeze food at -18°C. This allows you to avoid having to get rid of processed foods, meats or vegetables before your trip. This way, you get a working freezer and a preserved, dry refrigerator compartment.
⚠️ Attention: Do not leave perishable food in the refrigerator compartment in vacation mode, even if it seems that it is still cold there. The temperature of +15°C is not sufficient for storing milk, meat or ready meals.
Preparing the refrigerator before activating the mode
Before pressing the buttons on the control panel, it is necessary to carry out a number of preparatory measures. Simply switching the mode is not enough if there is food or dirt left inside. The first step should be a complete audit of the contents of the main compartment. Remove everything that can deteriorate when the temperature rises, even slightly.
Next you should do a thorough cleaning. Even if the shelves seem visually clean, microscopic food debris at a temperature of +15°C can become an ideal environment for the development of microorganisms during your absence. Wipe all surfaces with a weak solution of soda or a special product for cleaning household appliances.
Pay special attention to the rubber seals. They need to be washed and dried. If you leave the door closed with dirty rubber bands, there is a high risk of black mold appearing in the folds of the material, which is then very difficult to remove. Also check the drainage hole on the back wall - it should be free of debris so that condensation can evaporate freely.

Instructions: how to enable the function on different models
The activation algorithm depends on the type of control of your device. In modern models with an electronic display, this procedure is usually standardized, but has its own characteristics. Owners of mechanically controlled equipment will have to act differently, relying on physical controls.
For devices with a digital interface, most often you need to hold a certain button for 3-5 seconds. The corresponding indicator should light up on the display, often depicting a palm tree or a suitcase. In some models from Samsung or LG you need to press the key combination sequentially, for example, Freeze and Cool at the same time.
If you have a mechanical refrigerator, where the temperature is controlled by a rotary knob from 1 to 7, The concept of "vacation mode" is implemented physically. You don't have to look for hidden buttons. It is enough to move the regulator to the minimum cold position (usually number 1) or to a special position, indicated by a snowflake or the letter V (Vacation), if provided by the design.
| Brand | Control type | Action for activation | Indication |
|---|---|---|---|
| Liebherr | Electronic | Press the Vacation button | The suitcase symbol is lit |
| Bosch | Touch | Touch the icon suitcase | Indicator lights up |
| Indesit | Mechanical | Knob to minimum (1) | Absent |
| Electrolux | Electronic | Hold button 3 sec | Symbol flashing |
What to do if an error appears on the display?
If, after turning on the holiday mode, an error code appears on the display (for example, E01, F5), this may indicate a malfunction of the temperature sensor or a door leak. Try unplugging the refrigerator for 15 minutes, then turning it on again. If the error recurs, contact the service center.
Nuances of working with the No Frost and Full No Frost system
Owners of equipment with the system No Frost must take into account the peculiarities of air circulation. In such models, the holiday mode often implies not only a change in the target temperature, but also a change in the fan operation algorithm. They can go into sleep mode, turning on only to briefly circulate air to prevent stagnation.
In systems Full No Frostwhere cooling occurs in both the refrigerator and freezer compartments through common channels, it is important to ensure that the dampers that regulate the flow of cold air do not close completely. The electronics themselves control this process, but the user should know: if you hear rare clicks or buzzing every few hours, this is normal, the system maintains temperature balance.
Particular attention should be paid to models with a freshness zone (Zero Zone). In holiday mode, this function is usually forcibly disabled, since maintaining 0°C is not economically feasible. The temperature in the entire volume of the refrigerator compartment is equalized to a single value set by the Vacation program.
What not to do in Vacation Mode
There is a common misconception that by turning on this mode, you can leave any food in the refrigerator “just in case.” This is a big mistake. As already mentioned, the temperature rises to +15°C. With such heat, the mayonnaise will separate, the cheese will become moldy, and the meat will begin to spoil after a few hours.
Another mistake is tightly closing all shelves and drawers. If you use containers, make sure they do not completely block the air flow to the temperature sensor if it is located inside the chamber. In some older models, this can lead to incorrect readings and more frequent operation of the compressor.
It is also not recommended to experiment with quick freezing (Super Freeze) or super-cooling in vacation mode. These functions conflict with the energy saving logic. If you accidentally activate them, the system may ignore the command or, conversely, exit the economy mode, which will lead to unnecessary energy consumption.
⚠️ Attention: Do not leave the refrigerator door slightly open, even if it is empty. In vacation mode, ventilation is not designed for a constant flow of warm air from the room, which can lead to freezing of the evaporator.
Actions after returning from a trip
When you return home, (the first thing) is not to rush to load the refrigerator with food. First you need to deactivate the holiday mode. To do this, press the same button as to turn it on, or move the mechanical regulator to the operating position (usually 3-4).
After switching, let the equipment run idle for 2-3 hours. During this time, the temperature will drop to operating +4°C, and the compressor will return to its normal cycle. If you load warm food at once, you will create excess load on the motor trying to cool a large volume.
Be sure to ventilate the chamber before loading. Despite the absence of mold, stagnant air could acquire a specific “preservation” smell. Wipe the shelves with a damp cloth and add lemon juice or vinegar to freshen the interior.
Possible problems and their solutions
Sometimes users are faced with a situation where, after returning, the refrigerator does not exit the economy mode or, on the contrary, does not want to go into it. In 90% of cases, the problem lies in sticking touchpad buttons or oxidation of the contacts of the mechanical regulator.
If the display is on, but there is no response to pressing, try resetting the settings. To do this, disconnect the device from the power supply for 10-15 minutes. This will reboot the control module (main board) and it will return to factory settings. After turning it on, try activating the function again.
In the case of mechanical models, if the handle turns too easily or, conversely, is stuck, the thermostat may need to be lubricated or replaced. Do not use excessive force to avoid breaking the plastic rod.
Why does the refrigerator hum loudly in vacation mode?
In Vacation mode, the compressor turns on less often, but can work longer in continuous cycles to maintain a stable temperature throughout. In addition, due to the infrequent operation of fans, the noise may seem more contrasting against the background of silence in the apartment. If the hum is not accompanied by vibration of the case, this is normal.
Is it possible to use vacation mode in the summer if you are leaving for a week?
Yes, you can and should. In summer, the ambient temperature (room temperature) is higher and the refrigerator works harder. Vacation mode will save you from electricity bills and reduce the load on the electrical network at home while you are away.
How much energy does this mode save?
Depending on the model and volume of the refrigerator compartment, savings can range from 30% to 50% of normal consumption. For a large two-chamber refrigerator, this can be about 1-1.5 kWh per day.
What to do if the electricity goes out during vacation?
If the lights are turned off, the vacation mode will not help - the refrigerator will defrost in the same way as in normal mode. The only plus is that when the electricity returns, it will begin to work less intensively if you left it in Vacation mode, but the food in the refrigerator compartment will still be spoiled if the outage lasted a long time.
Does it need to be washed after the vacation mode?
It is advisable to wipe the shelves with a damp cloth, since dust from the air currents could have settled on them during inactivity. A general wash with defrosting is required only if you notice an unpleasant odor or visible dirt.
