You just received a new refrigerator or moved the old one to a new place - and now you can’t wait to turn it on. But there is no need to rush: incorrect connection after transportation can lead to freon leakage or even freon leakage. In this article, we will look at how long you need to wait before turning it on for the first time, why it is important, and what to do if the refrigerator is turned on ahead of schedule. serious compressor failure, freon leak or even refusal of warranty repair. In this article, we will look at how long you need to wait before turning it on for the first time, why this is important, and what to do if the refrigerator is turned on ahead of schedule.
Manufacturers indicate different recommendations - from 2 to 24 hours - and this is not a whim, but a technical necessity. It all depends on type of compressor, tilt angle during transportation, ambient temperature and even brand of refrigerator. For example, models with inverter compressors (like LG or Samsung) require less time to “suck” than classic linear ones. And if the refrigerator was transported in winter at −10°C, you will have to wait longer than in summer at +20°C.
We have collected current data from the instructions of leading brands (Atlant, Indesit, Bosch, Liebert), opinions of repairmen and the physical principles of operation of refrigeration equipment. You will also learn how to check if the refrigerator is ready to turn on, and what to do if after transportation it does not cool or makes unusual sounds.
Why you cannot turn on the refrigerator immediately after delivery
The main reason is oil in the compressor. During transportation, especially if the refrigerator was transported lying down or at an angle, oil may leak from the compressor crankcase and get into refrigerant circuit. If you turn on the unit in this state:
- 🔧 The compressor will run dry, without lubrication, which will lead to jamming of the piston or overheating of the windings.
- ⚡ The load on the start relay will increase, which can cause short circuit.
- ❄️ The refrigerant (freon) will not be able to circulate normally, which is why the refrigerator will not freeze well or not at all will turn on.
The second problem is condensation. If the refrigerator was transported during the cold season, moisture will form on the inner walls and tubes. When turned on, it can freeze and block capillary tube (the thin channel through which freon moves), which will lead to failure of the cooling system.
The third factor is deformation of the seals. In a lying position, the door rubber bands may become wrinkled, and after turning on the refrigerator will not close well, letting warm air through. This is not a critical failure, but you will have to adjust the hinges or replace the seal.
How long you need to wait: table by type of refrigerator
Minimum waiting time depends on transport position, ambient temperature i compressor type. Below is a table with recommendations for different conditions:
| Compressor type | Transport position | Air temperature | Minimum waiting time |
|---|---|---|---|
| Linear (regular) | Standing | From +10°C to +30°C | 2–4 hours |
| Linear | Angle (up to 40°) | From +10°C to +30°C | 6–8 hours |
| Linear | Lying (horizontally) | Any | 12–24 hours |
| Inverter | Standing or under angle | From +10°C to +30°C | 1–2 hours |
| Any | Any | Below +10°C | Add +4 hours to standard time |
Critical: If the refrigerator was transported lying down, it cannot be turned on earlier than after 12 hours - even for inverter models. This is due to the risk of oil getting into the refrigerant circuit, which will lead to irreversible damage to the compressor.
For refrigerators with No Frost system (for example, Samsung RB30A3200SA or LG GA-B409SLGL) the waiting time is the same as for conventional models. But after turning on, they may take up to a day to completely stabilize the temperature due to the automated defrosting system.
⚠️ Attention: If the refrigerator was delivered in winter and it spent more than 2 hours in the cold, be sure to let it warm up to room temperature (at least +16°C) before turning it on. Otherwise, the electronics may fail due to condensation on the control boards.
How to check if the refrigerator is ready to turn on
You don’t always need to blindly wait 24 hours. Here 3 reliable ways determine that the refrigerator can be turned on:
- Checking the oil level in the compressor. Gently rock the refrigerator back and forth. If you can hear oil splashing inside the compressor (lower part at the back), wait further. If there are no sounds, the oil has returned to the crankcase.
- Controlling the case temperature. Touch the back wall (where the compressor is located). If it is cold, the refrigerator has not yet warmed up to room temperature. A warm case means that the condensation has evaporated.
- Visual inspection. Open the door and check if there are any drops of water inside on the walls or seal. If there is moisture, wait another 1-2 hours.
For models with display (for example, Bosch KGE39AW25R or Samsung RF23A9671SG), you can use the built-in diagnostics. Press the button Super Freeze (or similar) for 5-10 seconds - if no error E1 or F1 (compressor fault code) appears on the screen, you can turn on.
Check position during transportation (standing/lying down)
Measure the room temperature (should be ≥ +16°C)
Pump the refrigerator to check the oil in the compressor
Inspect the door seals for deformation

What happens if you turn on the refrigerator ahead of time
The consequences depend on degree of violation of rules i refrigerator type. Here are the most common problems:
- 🔥 Overheating of the compressor. Without oil, the piston rubs against the cylinder walls, which leads to jamming. In 80% of cases, the compressor will have to be replaced (cost - from 8,000 to 20,000 ₽).
- ⚡ Protection triggered. Modern models (for example, Indesit DF 4180 W) automatically turn off when overheated, but restarting may be possible blocked.
- ❄️ Condensate freezing. If the refrigerator was turned on at a low temperature, the moisture in the capillary tube will freeze and the cooling system will stop working.
- 🛠️ Freon leak. During a sudden start, the oil may block the valve, which will lead to depressurization of the circuit. The repair will cost 5,000–15,000 rubles.
The most dangerous scenario is water hammer. If oil gets into the refrigerant circuit and blocks the flow of freon, the compressor will operate at maximum load until the winding burns out. In this case, repairs will cost 60–80% of the cost of a new refrigerator.
Manufacturers (Atlant, Liebert, Beko) usually refuses the warrantyif the breakdown occurred due to violation of transportation rules. The warranty card always contains a clause about observing the waiting time before switching on.
Signs of breakdown after early switching on
The refrigerator hums, but does not freeze → jammed compressor or freon leak.
Ice appears on the back wall → condensate in the capillary tube has frozen.
The protection is activated 5-10 minutes after switching on → overheating of the compressor windings.
The door does not close well → the seal is deformed.
Features for refrigerators of different brands
Each manufacturer gives its own recommendations. Here are the key nuances for popular brands:
- 🔹 Atlant i Biryusa: Minimum time - 4 hours if transported standing. For horizontal transportation - 18–24 hours. The instructions indicate that at temperatures below +5°C the time increases by 2 times.
- 🔹 LG (models with an inverter compressor, for example, LG GA-B489YVQZ): 1-2 hours is enough if the refrigerator is not placed. For horizontal transportation - 12 hours.
- 🔹 Samsung: For series RB i RF s Digital Inverter - 2 hours standing, 8 hours lying down. The instructions contain a warning about the risk of damage to the SmartThinQmodule when turned on early.
- 🔹 Bosch i Siemens: 6 hours for vertical transportation, 24 hours for horizontal transportation. For models with VitaFresh (for example, Bosch KAN92VI30R), an additional check of the seals is recommended.
- 🔹 Indesit and Ariston: 4 hours standing, 12 hours lying down. The instructions indicate that when transporting in winter you need to wait a day.
For built-in refrigerators (for example, Electrolux ENE34200OX) the rules are the same, but before turning on you need to check ventilation gaps (at least 5 cm at the back and on the sides). If the refrigerator is built into a furniture box, and the oil has not had time to drain, the risk of overheating increases 3 times.
⚠️ Attention: For refrigerators with two compressors (for example, Liebert Comfort CDF 380) the waiting time is calculated separately for each circuit. If one compressor is responsible for the freezer, and the other for the refrigerator compartment, and the refrigerator was transported lying down, you will have to wait 24 hours for both.
What to do if the refrigerator was already turned on ahead of time
If you or the delivery person violated the rules, do not panic. Here action algorithmwhich will help minimize risks:
- Immediately unplug the refrigerator. Even if it works fine, let it cool for 1-2 hours.
- Check the compressor. Touch it with your hand - if it is hot (more than +60°C), wait until it cools down to room temperature.
- Inspect the back wall. If there is frost on the pipes or compressor, it means the condensate is frozen. In this case, you cannot turn on the refrigerator for 12–24 hours.
- Check the first hours of operation. After turning it on again, listen:
- ✅ Normal: quiet humming, uniform hum.
- ❌ Dangerous: loud knocking, grinding, frequent relay clicks.
If the refrigerator turns on, but does not freeze or gives an error (for example, E1, F2, H1), do not try reboot it repeatedly. Contact the service center, indicating that you violated the transportation rules. In 30% of cases, technicians will be able to save the compressor by bleeding the system (cost - from 3,000 ₽).
For models with electronic control (for example, Samsung RS62R5001M9) after early switching on, the firmware may fail. In this case, resetting the settings will help: press Power Cool + Fridge for 10 seconds.
Additional installation tips after delivery
In addition to the waiting time, there are a few more nuances that will help avoid problems:
- 📏 Level the refrigerator. Use a level to make sure that it is level (allowable slope is no more than 2°). An uneven position leads to improper oil circulation.
- 🔌 Check the socket. The refrigerator must be connected to a separate grounded outlet. Using extension cords or tees increases the risk of power surges.
- 🌡️ Adjust the temperature. After turning on for the first time, set the average values: +4°C for the refrigerator and −18°C for the freezer. After 6-8 hours, you can adjust.
- 🚪 Do not load food immediately. Let the refrigerator run empty for 2-3 hours to stabilize the temperature.
For models with ice generator (for example, Liebert Premium LRP 60) must be flush the systembefore the first use. To do this:
- Pour 1-2 liters of clean water into the dispenser.
- Press
Ice Maker Reset(or holdIce Type5 seconds). - Drain the first batch of ice - it may contain dust particles from transportation.
If the refrigerator is equipped with vacuum insulation (technology Vacuum Insulation Panelas in Panasonic NR-BN30A1), Avoid sudden changes in temperature in the first day. For example, do not place it next to a radiator or in a draft.
FAQ: Frequently asked questions about turning on the refrigerator after delivery
Is it possible to reduce the waiting time if the refrigerator was transported in a warm van?
No. Transport temperature only affects the risk of condensation, not the oil drainage from the compressor. Even if the refrigerator was transported in a heated cabin, in a horizontal position you need to wait 12-24 hours.
What to do if the courier turned on the refrigerator immediately after delivery and left?
Unplug the refrigerator, let it stand for 6-8 hours, then turn it on again. If during the first 30 minutes of operation no unusual sounds or errors appear on the display, most likely there were no breakdowns. But during the week, monitor the temperature in the chambers - if it does not correspond to the set one, contact the service.
Is it necessary to wait if the refrigerator was transported in its original packaging “on its side” with a “Do not put” sticker?
Yes, it is necessary. The “Do not place” sticker means that the manufacturer does not guarantee safety during horizontal transportation, but even if the box was in the correct position, the inside of the refrigerator could move. The minimum waiting time is 6 hours.
What to do with a refrigerator that was stored in a warehouse at −5°C?
If the refrigerator was not turned on in the warehouse, after delivery home, let it warm up to room temperature (at least +16°C) for 4-6 hours. Only after this can you connect to the network. To speed up the process, do not use heaters - sudden heating is harmful to the seals.
Is it possible to transport the refrigerator lying down if you carefully lay it on its side?
No. Even with careful installation, oil from the compressor will enter the circuit, and the refrigerant will be redistributed unevenly. If it is impossible to avoid horizontal transportation (for example, in an elevator or a narrow opening), after delivery, increase the waiting time to 24 hours and before turning on, check the compressor for the presence of oil (by rocking).
