Transporting the refrigerator in a horizontal position is a necessary measure that can result in serious damage if you do not follow the rules for preparing for launch. Even a short-term stay of the equipment “on its side” leads to displacement of oil from the compressor and the risk of water hammer when turned on. Manufacturers clearly regulate the time intervals for settling, but these recommendations vary depending on the model, type of refrigerant and even the ambient temperature.
Many users mistakenly believe that it is enough to wait “a couple of hours” and they can connect the refrigerator to the network. In practice, this is fraught with failure of the compressor, the cost of repair of which can exceed half the price of a new device. In this article we will analyze physical reasons for the mandatory pausethe official instructions of leading brands (Samsung, LG, Indesit, Atlant), as well as the nuances for refrigerators with system No Frost and inverter compressors.
We will pay special attention myths: for example, why “turning the refrigerator on the other side” does not save you from risks, and what to do if the appliance has already been turned on ahead of time. At the end there is a checklist for checking functionality after the first start and answers to common questions that are not covered in standard instructions.
Why can’t you turn on the refrigerator immediately after transporting it lying down?
The main danger lies in the design of the compressor - the “heart” of the refrigerator. During horizontal transportation, the oil, which is normally located at the bottom of the compressor, spreads through the pipes of the cooling system. If you turn on the power immediately, the following will happen:
- 🔧 Water hammer: the compressor is trying to compress not the gas (refrigerant), but the oil, which is not compressible. This leads to mechanical damage to the pistons or valves.
- ⚡ Overheating of the windings: without lubrication, the rubbing parts of the compressor overheat, which can cause an interturn short circuit.
- ❄️ Clogged capillary tube: oil, that gets into the system, clogs thin channels, impairing the circulation of the refrigerant.
In modern models with inverter compressors the risks are higher: their design is more sensitive to a lack of oil. For example, in refrigerators Samsung RB*** or LG InstaView even short-term operation without lubrication can lead to failure of the electronic control unit.
An additional factor is type of refrigerant. In older models (before 2010), it was often used R-12 or R-22, which are less critical to mixing with oil. Modern refrigerants (R-600a, R-134a) are more aggressive and require precise dosage of oil in the system.
Official recommendations from manufacturers: timing table
Manufacturers indicate the minimum settling time in the instructions, but this data is often lost or ignored. Below is an updated table for popular brands (data confirmed by service centers in 2026):
| Brand | Models | Settling time (hours) | Notes |
|---|---|---|---|
| Atlant | All series | 6–8 | For models with No Frost —at least 10 hours |
| Samsung | RB, RS, RF | 8–12 | Inverter compressors require 12 hours |
| LG | InstaView, Door-in-Door | 10–14 | When transporting in cold weather - up to 18 hours |
| Indesit, Ariston | BAA, BIA, EBI | 4–6 | Exception - models with the system Total No Frost (8 hours) |
| Beko, Vestfrost | All series | 6–10 | For refrigerators with a volume of over 300 liters - +2 hours |
Critical information: Refrigerators with the system No Frost require 20–30% more settling time due to additional fans and the complex trajectory of the tubes, where oil can be retained.
If the instructions for your model indicate a time of less than 4 hours (for example, some Bosch or Siemens), this only applies to vertical transportation. For horizontal transportation, even such models, experts recommend at least 6 hours.
How to properly defend a refrigerator: step-by-step instructions
Simple waiting does not guarantee safety. It is important to follow the sequence of actions:
- Installation in a vertical position: Carefully place the refrigerator on a flat surface. Use a level to make sure there is no tilt (allowable angle is no more than 2°).
- Cleaning the back wall: Remove transport fasteners, dust and check the integrity of the tubes. Models Liebert or Haier often have additional compressor clamps - they need to be removed.
- Room temperature: The refrigerator should settle at +18–25°C. If it was brought from frost, wait until the condensation on the back wall evaporates.
- Checking the compressor: 2-3 hours after installation, lightly rock the refrigerator back and forth. If you hear an overflow of liquid inside, the oil has not yet returned to the compressor.
Make sure that the outlet is grounded and can withstand the load|Check the integrity of the door seal|Open the door for 10–15 minutes to equalize the pressure|Set the thermostat to position "2" or "Min" for the first start-->
For refrigerators with electronic control (for example, Samsung Family Hub) before turning on, reset the settings: press and hold Power Cool + Power Freeze for 10 seconds.
⚠️ Attention: If the refrigerator was transported in a lying position for more than 24 hours (for example, during long journeys), the settling time increases to 18–24 hours, even for models with minimum requirements.
What to do if the refrigerator has already been turned on ahead of time?
If the equipment has worked for less than 5 minutes and you managed to turn it off, follow these steps:
- ⏳ Withstand double time lag (for example, instead of 6 hours - 12).
- 🔊 Listen to the compressor: normal sound - uniform buzzing without clicks or knocking.
- 🌡️ Check the temperature in the chambers after 1 hour of operation: it should drop to +8–10°C.
If the refrigerator has worked for more than 10 minutes and signs of malfunction appear:
| Symptom | Probable cause | Actions |
|---|---|---|
| The compressor hums, but does not cool | Clogged capillary tube with oil | Switch off for 24 hours, then restart. If it doesn’t help, call a technician |
| Frequent relay clicks | Hydraulic shock, damage to windings | Do not turn on! Compressor diagnostics required |
| Strong vibration | Compressor imbalance due to lack of oil | Turn off for 12 hours, check shock absorbers |
In models with linear compressors (for example LG Linear Cooling) even short-term operation without oil can lead to irreversible damage. In this case, independent repair is not recommended - the compressor needs to be replaced at a service center.
What happens if you ignore the recommendations?
According to statistics from service centers, 68% of compressor breakdowns in the first 3 months of operation are associated with violations of transportation rules. The average cost of repairs is from 8,000 to 25,000 rubles (depending on the model). In 15% of cases, the refrigerator cannot be restored.
Features for refrigerators with No Frost and inverter compressors
Appliances with the system No Frost require a special approach due to the presence of additional elements:
- 🌀 Fans: For horizontal transportation The blades may become misaligned, causing imbalance. Before turning on, check their rotation manually (carefully scroll with your finger).
- 🧊 Evaporator: In models Samsung Twin Cooling or LG DoorCooling+ the evaporator is located vertically - oil can accumulate in its lower part.
- ⚙️ Electronics: Control units (for example,
EBMin refrigerators Bosh) are sensitive to voltage drops when started incorrectly.
For inverter compressors (installed in Panasonic, Hitachi, Mitsubishi Electric) additional rules apply:
⚠️ Attention: Inverter compressors cannot be started at ambient temperatures below +10°C. If the refrigerator was brought in in winter, before turning it on, it must be kept in a heated room for at least 12 hours.
In models with double compressors (for example, Samsung RB7300), each compressor is settled separately. If the refrigerator was lying on the right side, the main compressor (for the refrigerator compartment) will require more time than the additional one (for the freezer).
Myths and misconceptions: what really doesn't work?
On the Internet you can find a lot of “tips” that are not only useless, but also dangerous. Let's look at the most common ones:
- 🔄 “Turn over to the other side”: Some users believe that if the refrigerator was lying on one side, it needs to be turned over to the other so that the oil “drains back”. This wrong - the compressor is not symmetrical, and such an action will only aggravate the oil displacement.
- ⏱️ "Two hours is enough": Even for compact refrigerators (volume up to 100 l) the minimum time is - 4 hours. For most models - 6–12 hours.
- 🔌 "Turn on for 5 minutes to let the oil run out": This is the most dangerous advice. A short start leads to hydraulic shock, since the oil does not have time to return to the compressor.
- ❄️ "If the freezer works, that means everything is in order.”: The compressor may function temporarily, but after 1-2 weeks a breakdown will occur due to lack of lubrication.
Another misconception - "modern refrigerators do not require settling". Even in 2023–2026 models with improved compressors (for example, Samsung SpaceMax or LG ThinQ), manufacturers retain the requirement for a pause after horizontal transport. Moreover, inverter systems use thinner oils, which take longer to return to the compressor.
Service centers note that up to 40% of warranty failures for compressors are associated precisely with ignoring transportation rules. At the same time, manufacturers have the right to refuse warranty repairs if the inspection report indicates that the refrigerator was transported lying down without following the instructions.
Additional precautions
In addition to the settling time, consider the following nuances:
- 🚛 Method of transportation: If the refrigerator was transported in a freight elevator or on an open platform, vibrations could displace internal details. In this case, add 2-3 hours to the standard time.
- 🌡️ Temperature mode: When transported in hot weather (+30°C and above), the oil becomes more fluid and takes longer to drain back. Increase the pause by 20–25%.
- 🔧 Self-diagnosis: After turning on, check:
- Condenser temperature (the rear grill should be warm, but not hot).
- Lack of ice on the tubes (indicates a refrigerant leak).
- Uniformity of cooling (the difference between the top and bottom shelves should not exceed 3–4°C).
For refrigerators with display (for example, Samsung Family Hub or LG InstaView ThinQ) after the first turn on, calibrate the sensors:
- Hold the button
Smart Freezingfor 5 seconds. - Select the menu item
Sensor Reset. - Confirm the reset by pressing
OK.
If the refrigerator is equipped with a function Vacation Mode (vacation mode), do not activate it in the first 24 hours of operation - this may cause a failure in the refrigerant circulation system.
⚠️ Attention: In refrigerators with ice generator (for example, LG Instaview Door-in-Door) after transportation while lying down, you must manually drain the water from the system. To do this, press and hold the button Ice Plus for 10 seconds.
FAQ: Frequently asked questions about turning on the refrigerator after transportation
Is it possible to speed up the settling process, for example, by tilting the refrigerator?
No, this will only increase the risk of damage to the compressor. The oil should drain naturally under the influence of gravity. Any manipulations (tilting, shaking) can lead to oil getting into the capillary tube.
What to do if the refrigerator has been lying on its side for less than an hour - also wait 6-12 hours?
Yes, even a short-term stay in a horizontal position requires full settling. An exception is if the refrigerator was transported at an angle of no more than 45° (for example, in the trunk of a car with fixation).
How to understand that the oil has returned to the compressor?
Main signs:
- When the refrigerator is rocked, you cannot hear the liquid pouring inside.
- When the compressor starts up, it makes a smooth hum without any extraneous sounds.
- After 30 minutes of operation, the back grill heats up evenly.
Is it possible to turn on the refrigerator immediately if it was lying on the back wall (and not on its side)?
No, this does not reduce risks. When transported on the rear wall, oil also enters the cooling system, and the compressor experiences increased load due to displacement of the shock absorbers.
What to do if, after turning on, the refrigerator works, but does not freeze?
Probable causes and solutions:
- Clogged capillary tube: Turn off the refrigerator for 24 hours, then restart. If this does not help, the system needs to be cleaned.
- Refrigerant leak: Check the tubes for oil stains. In this case, repair is needed.
- Electronic unit failure: Reset the settings (instructions are in the user manual).
