You just Have you purchased a new refrigerator or moved your old one to a new place - and now you can’t wait to turn it on? Stop! Failure to comply with the settling time after transportation is one of the main reasons for compressor breakdowns in the first months of operation. Even if the seller or courier assures that “you can turn it on right away,” it’s not worth the risk: LG, Samsung, Atlant and other manufacturers clearly regulate this process in the instructions.
In this article we will analyze exact settling times for different transportation conditions (lying/standing, winter/summer)and explain the physics process and give a checklist for a safe first start. We’ll also tell you what to do if the refrigerator has already been turned on ahead of time, and how to minimize the damage.
Why you can’t turn on the refrigerator immediately after transportation: the physics of the process
The main reason is oil in the compressor. During operation of the refrigerator, it is evenly distributed throughout the system, lubricating moving parts. During transportation (especially in a horizontal position), oil flows into the lower part of the compressor or tubes, exposing critical components. If you turn on the unit immediately:
- ⚙️ The compressor runs “dry” —without lubrication, the rubbing parts wear out 10–15 times faster.
- ❄️ The refrigerant does not circulate correctly —water hammer and rupture are possible tubes.
- 🔥 Overheating of the windings —the risk of a short circuit in the first hours of operation.
The second problem is condensation. When the temperature changes (for example, if the refrigerator was delivered in winter), moisture forms inside the system. When turned on, it can freeze in the capillary tubes, blocking the circulation of freon. The consequences range from loss of cooling capacity to complete failure.
What is water hammer in a compressor?
When turned on without settling, oil can accumulate in one place in the system. When the compressor starts, it tries to pump liquid (not gas), which causes mechanical shock to the piston. The consequences range from valve deformation to complete destruction of the compressor. Repairs will cost 50–70% of the cost of a new refrigerator.
How many hours does the refrigerator need to stand: table by conditions
The timing depends on transportation provisionsthe ambient temperature and the type of refrigerant. Below is the current data for modern models (2018–2026 production).
| Transportation conditions | Minimum settling time | Recommended time | Notes |
|---|---|---|---|
| Vertical position, room temperature (+15...+25°C) | 2 hours | 4 hours | For models with an inverter compressor (Samsung Digital Inverter, LG Smart Inverter) |
| Horizontal position (lying on your side/back) | 8 hours | 12–16 hours | Required for refrigerators with a linear compressor (Atlant, Indesit) |
| Transportation at temperatures below +5°C | 12 hours | 24 hours | Necessary to equalize the oil temperature and evaporate condensate |
| Transportation in an inclined position (angle >30°) | 6 hours | 8–10 hours | Relevant for Side-by-Side and two-door models |
Important! If the refrigerator was transported to frost (-10°C and below), the settling time increases to 36–48 hours. thickening of the oil and the risk of ice plugs forming in the system.
How to properly defend the refrigerator: step-by-step instructions
Just waiting is not enough. You need to ensure the right conditions so that the oil is evenly distributed and the condensation evaporates. Follow this algorithm:
Install the refrigerator on a flat surface (check with a level)
Adjust the legs for stability (the gap to the floor is 2-3 cm)
Remove the shipping bolts from the compressor (if any)
Make sure that the door opens/closes without effort
Leave the refrigerator alone for the recommended time (see table above)
-->
Step 1. Positioning. The refrigerator must be standing strictly vertical. If it was in a horizontal position, carefully place it and fix it. For models with No Frost allow a tilt of no more than 5°.
Step 2. Temperature regime. Optimal temperature indoors - +18…+22°C. If the refrigerator was delivered in winter, do not place it next to the radiator or heater: sudden heating will lead to condensation inside the system.
Step 3. Check before turning on. After settling:
- 🔍 Inspect the back wall for damage to the tubes.
- 📏 Check the gaps: on the sides - 5 cm, in the back - 10 cm (for ventilation).
- 🔌 Make sure the socket grounded and can withstand the load (for refrigerators with a power of >200 W).
What will happen? if you turn on the refrigerator ahead of time?
The consequences depend on degree of violation and the model of the refrigerator. Here are real cases from the practice of service centers:
- ⚠️ 1-2 hours instead of 4-6: increased noise during operation, reduction in compressor service life by 20–30%.
- ❌ Switching on immediately after horizontal transportation: water hammer in 60% of cases, repairs will cost 8-15 thousand rubles.
- ❄️ Ignoring the rules during winter transportation: ice plugs in the capillary tube, freon leakage (repair - 5–8 thousand rubles).
The most dangerous scenario is compressor breakdown on the first day. Manufacturers (Bosh, Liebherr, Electrolux) in such cases warranty repairs are refused, citing violation operating rules. Signs of malfunction:
- 🔊 The compressor hums, but does not start (overheat protection is triggered).
- ⏱️ The refrigerator runs for 5-10 minutes and turns off.
- 🌡️ The temperature in the chambers does not drop below +15°C.
Features for refrigerators of different brands
Manufacturers indicate their recommendations in the instructions. Here are the key differences:
| Brand | Minimum settling time | Features |
|---|---|---|
| Samsung (RB, RT, RS series) | 4 hours (vertical), 12 hours (horizontal) | For models with Twin Cooling Plus it is mandatory to check the tightness of the doors after transportation. |
| LG (GA, GC, GR series) | 6 hours (any position) | Inverter compressors are more sensitive to oil starvation. 24 hours are recommended for winter transportation. |
| Atlant, Indesit, Beko | 8 hours. (horizontal), 2 hours (vertical) | Linear compressors require strict timing. For Atlant with a system Total No Frost it is mandatory to check the fan after switching on. |
| Liebherr, Bosch | 12–24 hours (any conditions) | Premium models with electronic control can block startup if sensors detect unstable oil temperature. |
Attention! For refrigerators with absorption cooling system (for example, Electrolux ERN1300FOX) the rules are different: they can be turned on 1-2 hours after transportation in any position. But such models are rare - check the type of compressor in the product passport.
How to check the type of compressor?
Open the refrigerator passport and find the “Technical Specifications” section. Look for the lines:
- Compressor type: Linear/Inverter/Absorption
- Cooling system: Compressor/absorption
If there is no documentation, look at the back wall: absorption systems do not have a compressor (there is no black “barrel” with tubes).
Common mistakes when settling the refrigerator
Even experienced users sometimes break the rules. Here top 5 errorsthat lead to breakdowns:
- 🚫 Ignoring the position during transportation. “I drove it while standing, so I can turn it on in an hour”—40% of owners think so. But if the refrigerator tilted even slightly (for example, in the trunk of a car), the oil could move.
- 🔥 Heating of the refrigerator after winter transportation. Placing the unit next to the radiator to “warm up faster” is a gross mistake. A sharp temperature change leads to condensation inside the system.
- 🔌 Connection via an extension cord. The first connection should be directly into the outlet. Voltage surges in the extension cord can damage the starting relay.
- 📦 Forget to remove the shipping bolts. This is true for new refrigerators (Samsung, LG). The bolts secure the compressor during transportation, and if they are not removed, vibration during operation will damage the fastenings.
- ⏳ They do not withstand time for models with No Frost. Non-defrost systems have additional fans and heaters that are sensitive to moisture. For them, the minimum settling time is 6 hours.
FAQ: Answers to frequently asked questions
Is it possible to speed up the settling process, for example, by tilting the refrigerator?
No, this is dangerous. Sudden movements may allow oil to enter the refrigerant circuit, causing blockage in the capillary tubes. The only acceptable action is gentle rocking (amplitude no more than 15°) 4–6 hours after installation.
The refrigerator was turned on immediately after delivery, and it works. What to do?
Don't turn it off! Let it work for 12–24 hours in gentle mode:
- Set the temperature to medium (+5°C in the refrigerator, -18°C in the freezer).
- Do not load food in the first 6 hours.
- Watch for sounds: if the compressor has started “knocking” or buzzing too loudly - turn off the refrigerator and call a technician.
If after 24 hours the operation is stable, the risk is minimal. But after 3–6 months, we recommend diagnosing the compressor.
How to transport a refrigerator to minimize settling time?
The ideal option is vertical transportation in a cargo van with shock absorbers. If this is not possible:
- 🚛 Use the original packaging or special transport straps.
- 📏 When transporting horizontally, place the refrigerator on its side (not on the door or back).
- 🌡️ Avoid temperatures below +5°C in the transport cabin.
In this case, the settling time can be reduced to 4–6 hours (even after recumbent transportation).
Is it necessary to settle the refrigerator after moving around the apartment (for example, from the kitchen to pantry)?
If the refrigerator was moved vertical a short distance (up to 5 meters) on a flat surface, just wait 30–60 minutes. This time is needed to stabilize the oil in the compressor. If you carried it through flights of stairs or tilted it more than 30°, follow the standard rules (see table above).
Where in the instructions is it written about the settling time? I can’t find it.
Look for the section Installation or First activation. Often the information is hidden under the following points:
Transporting the applianceBefore first useImportant safety instructions
If the instructions are in a foreign language, use a translator for phrases wait before turning on or settling time. As a last resort, call the brand's support service (the number is on the box).
Remember: correct settling of the refrigerator this is not a whim of the manufacturers, but a physical necessity. The 2–3 hours saved can result in weeks of repairs or the purchase of a new unit. If in doubt, always choose maximum recommended time from the table.
