Buying a new refrigerator is always a joyful event, marking the renewal of household appliances in the kitchen. However, immediately after the unit is delivered to the apartment, a reasonable question arises: is it possible to turn it on immediately, or do you need to wait a certain time? Many users mistakenly believe that it is enough to simply plug the plug into the outlet and load the products, but such a rush can lead to serious damage to expensive equipment.
Proper preparation for the first start directly affects the service life compressor and overall efficiency of the cooling system. Modern models, be it Liebherr, Bosch or Indesit, require simple but critical rules of transportation and acclimatization. Ignoring these nuances often causes motor failure or a leak in the circuit.
In this article we will analyze in detail all stages of preparation, from unpacking to setting temperature conditions. You will learn why waiting times depend on the position of the equipment during transportation, how to check the functionality of the components, and what to do if the device makes unusual sounds. A competent approach to the first switch-on will allow you to avoid costly repairs and ensure stable operation of the equipment for many years.
Why you can’t turn on the refrigerator immediately after delivery
The main reason for the ban on instant start lies in the design features of the refrigeration unit. Refrigerant and special compressor oil circulate inside the system, which lubricates the rubbing parts of the engine. During transportation, especially if the equipment was tilted or shaken, oil could move from the compressor crankcase to the system circuits, for example, to the evaporator or condenser.
If you start the compressor at this moment, it will begin to work without sufficient lubrication, which will lead to rapid wear of the piston group or even jamming. In addition, the oil in the tubes creates a hydraulic blockage that prevents the normal circulation of freon. The pressure in the system will increase sharply, which can cause rupture of thin-walled tubes or damage to valves.
⚠️ Attention: Attempting to turn on the refrigerator immediately after vertical transportation without settling may lead to water hammer in the compressor. This is irreversible damage, which is often not subject to warranty repair, since service centers record traces of oil in the system that are not typical for factory defects.
The second important factor is temperature acclimatization. If the delivery was carried out in winter at subzero temperatures, condensation formed inside the electronic boards and on the contacts may cause a short circuit when suddenly heated. The electronics of modern models with the system No Frost are especially sensitive to humidity.
How long does it take to leave the equipment?
The duration of the rest period before turning on for the first time directly depends on the position in which the refrigerator was transported and what the ambient temperature was. Manufacturers of equipment, such as Samsung i LG, establish clear recommendations, violation of which will void warranty obligations.
In the case of vertical transportation, when the angle of inclination did not exceed 40 degrees, the oil usually remains in the crankcase or flows back quite quickly. However, to fully guarantee safety and evaporation of condensate, it is recommended to wait a certain time. In winter, this period increases, since cold metal takes more time to warm up to room temperature.
The situation changes dramatically if the refrigerator had to be transported lying down. In a horizontal position, the risk of oil entering the cooling system circuit is maximum. In this case, the process of gravitational flow of oil back into the compressor takes much longer. Hurry is unacceptable here.
| Conditions of transportation | Time of year | Recommended settling time |
|---|---|---|
| Vertical (angle < 40°) | Summer | 2–3 hours |
| Vertical (angle < 40°) | Winter | 4–6 hours |
| Horizontal (lying down) | Summer | 8–12 hours |
| Horizontal (lying) | Winter | 12–24 hours |
Preparation for the first launch: step-by-step instructions
Before connecting the device to the power supply, it is necessary to carry out a number of preparatory manipulations. They are aimed at ensuring proper ventilation and safe operation. First, carefully remove all packaging, including cardboard, foam, and protective film.
Pay special attention to internal shipping tape or tape that may secure shelves and drawers inside the chambers. Their removal is necessary, since during operation of the mechanism they can damage the plastic or jam the retractable systems. Also check that all stickers have been removed from the inner walls.
☑️ Check before turning on
The next stage is installing the refrigerator in a permanent place. For correct operation of the heat removal system, it is necessary to provide a gap between the rear wall of the device and the wall of the room. Typically a minimum of 5-10 cm of free space is required. Side clearances are also desirable, especially if the refrigerator is built into a niche.
After installation, check the horizontal position of the cabinet using a building level. Adjustment is carried out by rotating the front support legs. Correct installation will prevent vibration and excessive noise during compressor operation. The doors should close tightly and be brought to the stop on their own when opened slightly.
First switching on and checking operation
After the required settling time has elapsed, you can begin connecting. Plug the plug into a separate grounded outlet. The use of extension cords or tees is not recommended, as the starting currents of the compressor can be high, which creates a risk of overheating of the contacts and fire.
When you turn on, you may hear a characteristic hum or gurgle - this is normal. The refrigerant begins to circulate through the system. Modern inverter compressors operate almost silently, starting smoothly, while classic models can produce a louder start-up sound.
⚠️ Attention: If, after turning on, you smell burnt wiring or plastic, immediately unplug the device. This may indicate a manufacturing defect or damage received during shipping. Restarting without diagnostics is prohibited.
At this stage, do not load products into the chambers. The refrigerator must run idle to reach the set temperature. Usually this process takes from 2 to 6 hours, depending on the volume of the chambers and the ambient temperature in the room.
Adjusting temperature conditions
Modern refrigerators are equipped with electronic controls that allow you to precisely adjust the climate inside the chambers. After the first start-up, it is recommended to set average temperatures so as not to overload the compressor with extreme modes. For the main chamber, the optimal range is considered to be from +3°C to +5°C.
In the freezer compartment, the temperature should be set to -18°C. This is the standard value for long-term food storage, which stops the development of bacteria and preserves vitamins. Some models allow you to activate the Super Freeze or "Quick Freezing" mode.
Using the Quick Freezing function is justified only when loading a large volume of fresh food. In normal mode, it is better to keep this functionality turned off so as not to increase power consumption and equipment wear. Adjustment is carried out through the control panel on the door or inside the chamber.
What is a freshness zone and how to set it up?
The freshness zone (zero chamber) is a separate compartment where the temperature is maintained at about 0°C and humidity 50%. It's ideal for storing meat, fish and vegetables that you plan to cook in the coming days. In some models, the settings for this zone are automatic, in others, manual activation through the menu is required.
Typical mistakes during first use
Even carefully reading the instructions does not always save you from mistakes that users make in a hurry. One of the most common is loading warm food into the refrigerator that has just been turned on. This forces the compressor to work at its limit, trying to cool a large volume of heat.
Another mistake is installing the refrigerator close to the wall or in a niche without gaps. The disruption of heat exchange leads to the condenser (grid at the back) overheating. The protection system may turn off the compressor, or the service life of the equipment will be reduced significantly due to constant overheating of oil and freon.
Some users ignore the smell of plastic in the first hours of operation. A new device always has a specific technical smell that must disappear. However, if it does not go away within a day or gets worse, this is a reason to contact the service. Also, do not touch the inner walls of the chamber with gloved or dirty hands, so as not to damage the coating.
Always check the current documentation that comes with your specific model, as manufacturers can make changes to the design without notice.
Is it possible to turn on the refrigerator if it has been standing in the cold?
It is strictly forbidden to turn on the device immediately after bringing it in from the frost. You need to let it warm up to room temperature for at least 4-6 hours. Running a cold compressor with congealed oil will cause it to break. Also, condensation on the contacts will cause a short circuit.
Why does the refrigerator hum loudly after turning it on for the first time?
Humming, gurgling and clicking are normal sounds for a new refrigerator. They are caused by the circulation of freon, the expansion of plastic parts from the cold and the operation of the compressor. If the sound does not sound like scraping metal or knocking, there is no need to worry. After a few days, the equipment will get used to the installation location.
Do you need to wash the refrigerator before first use?
Yes, definitely. Factory dust and the smell of plastic and packaging may remain inside the cameras. Wipe the interior surfaces with a soft cloth soaked in a weak soda solution or a special liquid for washing refrigerators. After this, wipe all surfaces dry and leave the doors open for 30 minutes to ventilate.
What to do if the refrigerator does not freeze after turning it on?
After the first turn on, the refrigerator takes time (up to 6 hours) to gain temperature. If after 6-8 hours of operation in empty mode the cold does not appear, check that the doors are tightly closed and that the settings are set correctly. If the problem persists, contact an authorized service center.
