Buying a new household appliance is always an exciting moment, especially when it comes to large-sized appliances such as refrigerator. After the movers carefully brought the box into the apartment, unpacked the unit and installed it in the kitchen, most owners have one key question: when can they finally press the power button? Haste in this matter is the main enemy of the proper operation of the compressor.
Many people mistakenly believe that it is enough to simply plug the cord into the outlet as soon as the device is in place. However, the physics of the refrigeration circuit dictates its own strict conditions. The oil in the system may have shifted during transportation, and it takes time to return to its normal position in the compressor crankcase.
Ignoring the initial start-up rules can lead to serious damage that will not be considered a warranty case. In this article we will analyze all the nuances depending on the method of transportation, ambient temperature and design features of your model.
Why you can’t turn on the refrigerator right away
The main reason for the ban on instant start lies in the design of the compressor and the properties of the refrigerant. While driving, especially if the road was uneven or the box was tilted, freon could leak from the crankcase into the freon circulation circuit. If you start the engine at this moment, it will work without lubrication, which will lead to rapid wear and jamming. compressor oil could leak from the crankcase into the freon circulation circuit. If you start the motor at this moment, it will run without lubrication, which will lead to rapid wear and jamming.
In addition, there is refrigerant in the circulation system. If there is strong shaking or a sudden change in the position of the body, it could mix with oil or get into areas where it should not be. A sharp start of the compressor in the presence of liquid freon in the compression chamber will cause hydraulic shockwhich can destroy the valves or the piston itself.

⚠️ Attention: Even if the refrigerator was transported in a strictly vertical position, the vibration when the truck moves on public roads is enough to disrupt the uniform distribution of technical fluids within the system.
Another important factor is the temperature regime. If equipment comes into a warm room from frost, condensation will form inside. Moisture on the electrical contacts may cause a short circuit when first turned on. Therefore, acclimatization is necessary not only for the oil, but also for drying the internal components.
How long should the refrigerator sit?
The waiting time directly depends on the position in which your new purchase was transported. Manufacturers of equipment, such as Bosch, LG or Indesitusually indicate minimum terms in the instructions, but there are general rules that are relevant for most models.
If the refrigerator was transported in a vertical position, which is the ideal scenario, then the process of draining the oil back into the compressor takes less time. Usually it is enough to wait from 2 to 4 hours. During this time, gravity will do its job, and the lubricant will return to the lower part of the motor.
The situation changes dramatically if the equipment had to be transported lying down. In this case, oil may have leaked deep into the evaporator or condenser. It takes much more time for it to completely drain - experts recommend a pause of 8 to 12 hours, and in some cases up to a day.
The temperature factor also plays a role. If the refrigerator was taken out of the car in the cold in winter, let it warm up to room temperature. A sharp temperature change can damage plastic parts and seals.
The table below will help you navigate the waiting time depending on transportation conditions:
| Transportation conditions | Outdoor temperature | Recommended time sludge | Risk of inclusion |
|---|---|---|---|
| Vertical | Warm season | 2-4 hours | Low |
| Vertical | Winter (frost) | 4-6 hours + warming up | Medium (condensation) |
| Horizontal (lying down) | Warm season | 8-12 hours | High (oil) |
| Horizontal (lying) | Winter (frost) | 12-24 hours | Critical |
The influence of winter transportation on the launch
The winter period makes its own adjustments to the process of installing household appliances. If your new refrigerator has spent several hours in an unheated truck bed at temperatures below -5°C, there is absolutely no rush to turn it on. Cold affects not only the oil, which becomes more viscous, but also the case materials.
Plastic elements, shelves and drawers become fragile in the cold. Attempting to immediately open the door or install heavy products may result in cracks. In addition, sudden heating of cold plastic can cause its deformation.
The biggest danger is condensation. When cold metal enters a warm apartment, moisture from the air begins to settle on its surface, and more importantly, inside electrical circuit boards and on contacts. If you turn on the appliance while wet, a short circuit will occur short circuit.
⚠️ Attention: Do not try to speed up the process of warming up the refrigerator using heaters, hair dryers or heat guns. Uniform natural heating is the only safe way.
The acclimatization time in winter should be increased. Even if you transported the refrigerator vertically, let it sit warm for at least 6-8 hours before plugging it in. This ensures that all internal components have reached room temperature and are dry.
What to do if the refrigerator is very frozen?
If you notice frost inside the chambers or on the seals, do not turn on the appliance. Leave the doors open until the ice has completely disappeared and the moisture has dried. This can take up to a day.
Installation and preparation rules
Before thinking about connecting to the power grid, you need to properly prepare the installation site. The refrigerator should not be placed close to a wall or furniture. For efficient operation of the cooling system, air circulation is required around the radiator, which is usually located on the back wall or on the sides.
The optimal distance to the back wall should be at least 5-7 cm, and about 10 cm on the sides. If you have a built-in model, make sure that the ventilation grilles in the furniture are not closed and comply with the manufacturer's requirements.
An important step is the alignment of the body. If the refrigerator is positioned crookedly, the doors may not fit tightly, which will lead to ice freezing and increased load on the compressor. Use adjustable supports (legs) at the front to achieve the ideal horizon.
Check the integrity of the rubber seals on the doors. They must be clean and elastic. Dirt or damage to the seal will disrupt the seal of the chamber, and the refrigerator will run idle, consuming excess electricity.
☑️ Ready for the first start
Step-by-step instructions for the first start-up
When the required waiting time has passed, and you are sure that the oil has cleared and the condensate has dried, you can proceed to the first start-up. This process should be carried out in stages to avoid peak loads on the electrical network and cooling system.
First, turn on the refrigerator without loading food. Leave empty chambers running at minimum power (usually "1" or "Eco" mode). Let the device run idle for 2-4 hours. During this time, it will reach the desired temperature, and the compressor will automatically turn off.
After the refrigerator has turned off for the first time, you can start loading. Do not add a lot of warm foods at once. It is better to fill the chambers gradually, in small portions, giving the system time to cope with the cooling of the new mass.
Pay attention to the noise level when starting for the first time. The compressor may work a little louder than usual in the first minutes, but then the sound should become smooth and quiet. If you hear knocking, grinding or loud humming, immediately unplug the appliance.
It is important to set the temperature correctly. For the main compartment, the optimal temperature is +4...+5°C, and for the freezer -18°C and below. Do not immediately set the minimum possible values, this will force the compressor to work without interruption.
Typical mistakes when starting equipment
Even knowing the rules, users often make mistakes that shorten the life of the equipment. One of the most common is to install the refrigerator next to (heat sources) such as a radiator, oven or direct sunlight. This causes the compressor to wear out.
Another mistake is loading with hot products. If you put a pot of soup in a refrigerator that has just been turned on, the temperature inside will jump sharply. The compressor will try to compensate for this heat and may burn out from overload, since it is not designed for sudden changes in temperature load.
The need for defrosting before the first turn on is also often ignored if the refrigerator was defrosted before transportation. Moisture remaining in the drainage system may freeze and clog the condensate drain, causing puddles to appear under the drawers.
⚠️ Warning: Never use sharp objects to remove ice or packaging from inside the drawers. Damage to the evaporator (tubes inside the wall) will lead to freon leakage and expensive repairs.
Do not forget about electrical safety. The refrigerator should only be connected to a working outlet with grounding. The use of cheap extension cords or tees can cause poor contact and fire.
Frequently asked questions (FAQ)
You can Is it possible to turn on the refrigerator if it has been standing for only 30 minutes?
It is strictly not recommended. Even with vertical transportation, 30 minutes is too short for the oil to drain. The minimum safety threshold is 2 hours, but it is better to wait 3-4 hours to eliminate the risk of water hammer in the compressor.
What will happen if I turn on the refrigerator ahead of time?
In the best case, nothing will happen, and the oil will have time to drain. In the worst case, the compressor will start “dry”, which will lead to it jamming, or a hydraulic shock will occur, which will destroy the valve group. Repairs in this case will be very expensive.
Do you need to wash the refrigerator before turning it on for the first time?
Yes, definitely. There may be particles of factory grease, dust, or the smell of new plastic left inside. Wipe all surfaces with a damp cloth and a mild detergent and allow them to dry completely before plugging in.
Why does the refrigerator hum loudly after first turning it on?
During the first hours of operation, the compressor may make louder sounds as the system enters operating mode. The sound of freon gurgling may also be heard. If the noise does not subside after a day or is accompanied by vibration of the case, contact service.
Is it possible to transport a refrigerator in cold weather at -20 degrees?
Technically it is possible, but with caution. The main problem is not the cold, but the temperature difference when adding heat. After such transportation, the refrigerator should stand in a warm room without connecting to the network for at least 12-24 hours to equalize temperatures and evaporate condensation.
