Purchasing new household appliances or moving to a new apartment is always an exciting process associated with many organizational issues. One of the most important points is the correct installation of large equipment, in particular the refrigeration unit. Owners often ask the question: how long before it is possible to turn on an LG refrigerator after transportation, so as not to damage expensive equipment on the very first day of operation?
Numerous forums and advice from friends offer diametrically opposed opinions: from “turn on immediately” to “wait for three days.” The truth, as often happens, lies in the technical features of the device and the conditions in which it was transported. Compressor, which is the heart of the system, is extremely sensitive to the position in which it was during movement and the ambient temperature.
Ignoring the rules for the initial start-up can lead to failure building refrigerant or oil, which will entail expensive repairs or complete replacement of the unit. In this article, we will analyze in detail the physical processes occurring inside the unit and give clear time frames for different situations so that your LG serve for many years without failure.
Physical processes inside the refrigeration system during transportation
To understand the need for waiting, you need consider the internal structure of the refrigerator. The basis of the system is a closed circuit through which the refrigerant circulates, and the compressor acts as the driving force. Inside this compressor there is a special compressor oilthat lubricates the rubbing parts and ensures the tightness of the piston group.
In the normal, vertical position, the oil is located in the lower part of the compressor, in the crankcase. However, during transportation, especially if the unit was tilted at an angle of more than 40 degrees or was transported lying down, oil could flow into the circuit tubes. If you start the engine immediately, oil may enter the coolant circulation system, which will lead to a clogged capillary tube or water hammer.
In addition, with active shaking and vibration while driving on rough roads, the oil could mix with the coolant, forming an emulsion. Separating these environments requires time and rest. The minimum rest time for stabilizing the oil in the compressor crankcase is 2-4 hours during summer transportation in a vertical position..
Another factor is the temperature regime. If transportation was carried out in winter at subzero temperatures, the condensation that formed inside the electrical components when brought into a warm room should evaporate. Turning on wet electronics may cause a short circuit.
⚠️ Warning: Attempting to start a compressor with oil in the system may cause permanent damage to the valves. Recovery from such an incident often requires a complete recharge of the system and replacement of the compressor.
Thus, waiting time is necessary not only for the oil to drain, but also to equalize temperature conditions and evaporate moisture. Refrigerant must take its original position, and all seals must straighten out after compression during transportation.
Dependence of the waiting time on the method of transportation
The time after which you can turn on the LG refrigerator directly depends on how exactly it was moved. Manufacturers give different recommendations for vertical and horizontal transportation, since the risks in these cases differ significantly.
If the refrigerator was transported in a strictly vertical position, carefully secured in the back of a truck, and the tilt angle did not exceed 40 degrees, then the process of oil migration was minimal. In this case, it is enough to let the unit stand in the room for 2-3 hours. This time is enough for the pressure in the system to stabilize and any suspended oil to settle.
The situation changes dramatically if the equipment was transported lying down. In a horizontal position, oil is guaranteed to flow into the evaporator and condenser tubes. It takes much longer for it to completely drain back into the compressor crankcase. The minimum period in this case is 8-12 hours, and some experts recommend keeping the unit for up to a day.
It is also worth considering the intensity of the shaking. Even when transported vertically over a rough road, the oil could foam violently. In such cases, it is better to increase the settling time. Below is a table with approximate time intervals.
| Conditions of transportation | Season | Recommended waiting time | Risk of damage |
|---|---|---|---|
| Vertical, without tilt | Summer | 2-3 hours | Low |
| Vertical, with an inclination >40° | Summer | 4-6 hours | Medium |
| Horizontal (lying) | Summer | 8-12 hours | High |
| Any position | Winter (frost) | 4-6 hours + warming up | Average (condensation) |
Don’t rush things. A few hours of waiting is a negligible price compared to the cost of repairing or buying a new device. It is better to play it safe and wait for the recommended time.
Seasonal features: transportation in winter and summer
The time of year in which transportation occurs makes adjustments to the installation process. In summer, the main problem is overheating and dilution of the oil, in winter - condensation and solidification of lubricants.
When transported in the summer heat, the oil in the compressor becomes more liquid and flows more easily through the system. However, high temperatures contribute to faster evaporation of moisture. The main rule of summer is not to turn on the refrigerator immediately after a hot street if it was standing in the sun. Allow it to cool to room temperature so that the thermostat reads correctly.
Winter transportation carries a hidden danger - condensation. When you bring a cold refrigerator from the cold into a warm apartment, moisture appears on the internal parts, including electrical contacts and the control board. If you turn on the device immediately, a short circuit may occur.
In addition, compressor oil thickens in cold weather. Starting the engine with frozen oil will lead to dry operation in the first seconds, which is critically dangerous for the bearings and piston group. The oil must warm up to room temperature to acquire the required viscosity.
What to do if the refrigerator is frozen?
If the unit has been in the cold for more than 2 hours, bring it indoors, unpack it and leave it turned off for at least 6-8 hours. Do not connect to the network until the temperature of all nodes is equal to room temperature.
LG service center specialists LG recommend increasing the standard standby time by 2-3 hours in winter. This ensures that all condensation evaporates and the oil reaches a working consistency. Do not try to speed up the process with heaters or hair dryers - a sharp temperature change can damage the plastic and seals.
Specifics of LG models: No Frost and conventional systems
LG refrigerators, like other modern equipment, are divided into models with the No Frost system (or Smart Inverter) and classic drip systems. Is there a difference in waiting time for different types?
Technically, the operating principle of the compressor is the same in all models. However, in refrigerators No Frost the system of tubes and channels is more branched and complex. Oil that gets into the defrost system or ventilation ducts may take longer to return to the crankcase. Therefore, for models with No Frost, it is recommended to adhere to the maximum waiting times, especially after horizontal transportation. Models with a linear inverter compressor (often found in premium LG series) are more sensitive to the quality of lubrication and the absence of water hammer. Inverter motors operate at different frequencies, and the presence of foreign liquids in the circuit can cause increased noise or vibration when starting.

- 🧊 For LG Total No Frost models, the minimum settling time after horizontal transportation is 10-12 hours.
- ⚙️ Inverter compressors require more careful adherence to the temperature regime before starting.
- 💧 In drip systems, oil drains faster, but there is a risk of moisture getting into electrics remain high in winter.
It is also important to consider the volume of the refrigeration chamber. Large two- and three-chamber models contain more oil in the system than compact single-chamber options. Consequently, they need more time to stabilize internal processes.
Algorithm for correct first switching on
The required time has passed, the refrigerator has settled. How to perform the first startup correctly to minimize stress on the equipment? There is a clear algorithm of actions that will ensure a long life for your unit.
First, you need to empty the refrigerator of all shipping packaging, tape and protective films. Pay special attention to internal fastenings, if any (some models come with fixed shelves). Remove all foreign objects from the chambers.
Next, wipe the internal surfaces with a damp cloth with the addition of a weak solution of soda or a special product for household appliances. This will remove industrial dust and the smell of new plastic. After washing, the doors should be left open for ventilation.
☑️ Preparation for the first start
Now you can connect the device to the network. However, you should not immediately load the refrigerator with food. Let it run idle for 3-5 hours. During this time, the unit will reach the required temperature, and the automation will turn off the compressor. Only after the first cooling cycle can you add food.
If you notice that after turning on the refrigerator makes unusual sounds (gurgling, loud hum), do not panic. This may be due to residual movement of refrigerant or oil. If the noise does not stop after 30-40 minutes of operation, turn off the device and contact service.
Typical errors during installation and startup
Even knowing the rules, users often make mistakes that shorten the life of the equipment. Analysis of calls to service centers allows us to identify the most common ones.
The first mistake is ignoring the instructions. Many people believe that “a refrigerator is a refrigerator” and act on instinct. However, each line LG may have its own nuances. The second mistake is installing it close to the wall. For normal air circulation around the condenser, it is necessary to leave a gap of at least 5-10 cm.
The third common mistake is loading warm food into a refrigerator that has not yet cooled down. This forces the compressor to wear out at maximum power for a long time, which is critical for a new device. The fourth mistake is using unstable voltage without protection.
⚠️ Attention: Power surges in the network can damage the electronic control module when turned on for the first time. It is recommended to use a surge protector or voltage stabilizer, especially in the private sector.
Also, users often forget to remove the shipping gaskets from door hinges. If they are not removed, the door will not close hermetically, which will lead to continuous operation of the compressor and the formation of ice.
Frequently asked questions (FAQ)
Is it possible to turn on the LG refrigerator immediately if you took it only 15 minutes to the dacha?
Yes, if it is being transported was carried out in an upright position, without strong shaking or bending, and it was warm outside. It is enough to let it stand for 30-60 minutes to stabilize the pressure. However, the risk always remains, so it is better to wait at least 2 hours.
What if I turned on the refrigerator immediately after transportation and it works?
If the device works normally, does not make strange sounds and gets cold, then you are lucky and the oil did not get into critical components. However, this does not mean that this can always be done. The compressor life may have been reduced. In the future, strictly observe the standing time.
Do you need to wash the refrigerator before turning it on for the first time?
Yes, definitely. Dust, packaging particles and factory odors may remain inside. Wipe the chambers with a weak solution of baking soda (1 tablespoon per liter of water) and wipe dry. This will also help disinfect surfaces.
Is it true that modern LG refrigerators can be turned on after 15 minutes?
This is a myth. The physical laws of the flow of liquids (oil) have not been canceled. Even in the most modern models with inverter compressors, the oil must return to the crankcase. 15 minutes may be enough only to equalize the temperature, but not to drain the oil.
Is it possible to transport a refrigerator in the trunk of a car?
It is highly not recommended. It is difficult to ensure a vertical position and fixation in the trunk. There is a high risk of severe tilting and vibration. If there is no other choice, transport only lying down, on a soft base, and after delivery, let it sit for at least 12-24 hours.
Following simple rules of operation and installation will allow your refrigerator LG operate reliably and efficiently throughout the entire declared service life. Do not neglect the recommendations, and the equipment will answer you with stable cold and silence.
