How long should a new refrigerator stand before turning it on for the first time: rules and exceptions

You have just purchased a new refrigerator, and the logical desire is to connect it to the network as quickly as possible, load it with groceries and enjoy stable job. However specialists and manufacturers they unanimously say: there is no hurry. The waiting time before turning on for the first time depends on the type of compressor, transportation conditions and even room temperature. Why is this so important?

The fact is that during transportation oil from the compressor it can get into the refrigerant circuit. If you turn on the refrigerator immediately, the oil will block the capillary tubes, which will lead to compressor overheating or breakdown in the first months of operation. Moreover, a sharp temperature change (for example, if a refrigerator was brought from the street in winter) can provoke condensation inside the system, which is also harmful for equipment.

In this article we will analyze exactly how much time is required for different models, what to do in emergency cases and how check if the refrigerator is ready to start. And also - common mythswhich may cost you your warranty.

Why can’t you turn on the refrigerator immediately after delivery?

The main reason is risk of water hammer in the compressor. During transportation, the refrigerator is tilted, shaken, and sometimes overturned (even if there are warning stickers on the box). As a result oil from the compressor crankcase it gets into the refrigerant pipes. When turned on, the compressor tries to drive oil through the system, but due to the difference in the viscosity of the liquids, the following occurs:

• 🔥 Overheating of the windings —the oil does not have time to lubricate the parts, friction increases, which leads to premature wear.
• ❄️ Frozen capillary tube —if oil has accumulated in a narrow place, the refrigerant does not circulate and the refrigerator does not cool.
• ⚡ Short circuit —in rare cases, the starting relay may burn out due to overheating.

The second problem is condensation. If the refrigerator was brought from outside in winter (at temperatures below +5°C), moisture will form inside the case and on the parts. When turned on, it can:

• 💧 Get on electrical contacts → risk of corrosion or short circuit.
• ☁️ Condense in the insulation → an unpleasant odor will appear over time.

Manufacturers (for example, Liebherr, Samsung, Indesit) indicate the minimum waiting time in the instructions, but often do not explain why it differs for different models. In fact, it all depends on the type of compressor:

How many hours should a refrigerator stand: table by type of compressor

The waiting time before turning on depends on the design of the compressor and transportation conditions. Below are the current recommendations for 2026 (check the instructions for your model, as some brands, for example Bosch, may tighten the requirements for new series).

Important: If the refrigerator was transported lying down (for example, in the trunk of a car), the waiting time increases by 1.5–2 times. This is due to the fact that the oil is guaranteed to get into the refrigerant circuit, and it will need more. time to drain back.

⚠️ Attention: Some sellers claim that “modern models can be turned on immediately.” This is a marketing ploy! hours. Samsung RB7000) requires a minimum exposure of 2–3 hours.

How to properly prepare the refrigerator for the first time: step-by-step instructions

Just waiting a few hours is not enough. To avoid breakdowns, follow this algorithm:

Make sure that the refrigerator is level (check with a level or leveling application)

Inspect the housing for damage (especially the back wall and compressor)

Wipe the internal surfaces with a weak soda solution (1 tbsp per 1 liter of water)

Remove all shipping bolts and brackets (usually on the compressor and door)

Connect to the network through a surge protector (not directly into the outlet!)

-->

Now in more detail about each point:

1. Alignment. Use a building level or an application on a smartphone (for example, Bubble Level). data-i="121">Alignment.
• 🔊 Increased noise during operation.
• 🚪 Spontaneous opening of the door (if the misalignment is >2°).
• 💔 Premature wear of the compressor (due to vibrations).

Removing the transport fasteners. Some models (for example Liebherr CN 4815) have special bolts that secure the compressor. If you do not remove them, you will hear a loud knock when you turn it on, and the part may be damaged.

First switching on. Connect the refrigerator to a power outlet with grounding. Avoid extension cords - they may not withstand the starting current of the compressor (up to 10 A in the first seconds).

Critical error: turning on the refrigerator in the first 30 minutes after delivery in winter can lead to the formation of ice in the capillary tube. This malfunction can only be corrected at a service center (repair cost - from 5,000 ₽).

What to do if the refrigerator was delivered in winter: accelerated preparation

If the refrigerator was delivered at a temperature below +5°C, and it is not possible to wait 12–24 hours (for example, the products have already been purchased), use this method:

1. Move the refrigerator to the warmest room (for example, next to the battery, but not closer than 50 cm).
2. Open the door for 1-2 hours - this will speed up the heating of the internal parts.
3. Use a fan directed at the rear wall (no closer than 1 m) to evenly warm up the compressor.
4. After 4-6 hours, carefully rock the refrigerator back and forth (amplitude 5–10°) so that the oil flows into the crankcase.

Warning: this method reduces the waiting time to 6–8 hours, but does not guarantee 100% safety. If the refrigerator is under warranty, it is better not to take risks.

Myths about turning on the refrigerator for the first time: what to believe?

There is a lot of advice on the Internet that is not only useless, but also harmful:

• ❌ “You need to turn on the refrigerator for 1 hour, then turn it off and turn it on again.”

  This is dangerous! Atlant And Beko) directly prohibit this method in the instructions.

• ❌ "If the refrigerator was turned on in the store, you can use it immediately."

  Even if the refrigerator was tested in the store, transportation could disrupt the distribution of oil. For example, in Samsung RL60 after delivery from another city, a minimum of 4 hours of waiting is required.

• ❌ "Add freon yourself if the refrigerator does not cool after turning on."

  This is a gross mistake! If the refrigerator does not freeze after the first start, the reason in 90% of cases is an air lock or oil in the system. Self-filling with freon without evacuation will lead to breakdown.

Another common question: "Is it possible to speed up the process if you put the refrigerator on its side?" No! This will only aggravate the problem - oil will get into the circuit, and it will take even more time to drain it.

What will happen if you ignore the rules?

In the best case, the refrigerator will last 20-30% less than the stated period (for example, instead of 10 years - 7). In the worst case, the compressor will burn out in the first months, and the warranty will not cover repairs, since operating conditions have been violated. Owners of inverter models (LG InstaView, Samsung Family Hub), where the cost of the compressor reaches 40% of the price of the refrigerator, are especially at risk.

Features for refrigerators with the No Frost system

Models with No Frost (Bosch KAN92VI30R, Indesit ITF 118) require additional precautions. In addition to the compressor, they have:

• 🌀 Fan - if condensation remains on it, it may jam when turned on.
• 🔄 Evaporator - during sudden cooling, ice forms on it, which blocks airflow.
• 💨 Temperature sensors —moisture can cause their operation to malfunction.

For such refrigerators:

1. Increase the waiting time by 20–30% (for example, if the table indicates 6 hours, wait 7-8).
2. After turning on, do not load food in the first 2-3 hours - let the system stabilize.
3. If the refrigerator has Twin Cooling (two cooling zones), check that both compressors have warmed up equally.

Signs that No The frost refrigerator is not ready for operation:

• 🔊 Loud hum of the fan (may indicate ice on the blades).
• ❄️ Rapid formation of frost on the back wall (which means the evaporator has not warmed up).

Checklist before the first turning on: how not to miss the important

Before pressing the power button, go through this list:

The refrigerator stood vertically for at least the time indicated in the table

The room temperature is above +16°C (optimally +18...+22°C)

All shipping bolts and brackets have been removed

The door opens/closes smoothly, without creaks

The socket can withstand a load of 10–15 A (check the technical data sheet of the refrigerator)

There is no visible condensation on the tubes and compressor

-->

If at least one point is not fulfilled, do not turn on the refrigerator. For example, if the room is +10°C, and the instructions indicate that the minimum operating temperature is +16°C, wait until the room warms up. Liebherr CBP 4856 It is indicated that the minimum operating temperature is +16°C, wait until the room warms up.

⚠️ Attention: In refrigerators with a display (for example, Samsung RS6HA8891B1) after The first time you turn it on, an error may appear E1 or F1. This is normal - the system is being calibrated. If the error does not disappear after 10–15 minutes, turn off the refrigerator and restart after 1 hour.

FAQ: Frequently asked questions about turning on the refrigerator for the first time

Is it possible to turn on the refrigerator after 1 hour if it has been standing in a warm room?

No. Even if the refrigerator was brought from the store (where it was turned on), transportation could disrupt the distribution of oil. The minimum waiting time is 2 hours for absorption models and 4 hours for others.

How can you tell that the oil has returned to the compressor and you can turn on the refrigerator?

Gently rock the refrigerator back and forth (amplitude 5–10°). If you can hear the liquid flowing inside, wait another 1-2 hours. In inverter models (LG GR-B207), you can put your hand on the compressor - it should be warm, but not hot.

What to do if the refrigerator was delivered lying down, and there is no time to wait 24 hours?

In this case, the risk of breakdown is extremely high. An alternative is to call a specialist for blowing the system (cost ~3,000 rubles). He will connect the refrigerator to a vacuum pump and remove the oil from the circuit. But the warranty does not cover such repairs.

Do you need to wash the refrigerator before turning it on for the first time?

Yes, but only dry cloth or with a weak soda solution. Do not use aggressive chemicals (for example Domestos) - they can damage the door seals. In models with AntiBacteria coating (Panasonic NR-BN30), it is enough to wipe the surfaces with damp microfiber.

Why does a new refrigerator run loudly after the first inclusions?

Is this normal in the first 2-3 days. Reasons:

• 🔄 Oil circulation through the system (may cause extraneous sounds).
• ❄️ Ice formation in the freezer (in models without No Frost).
• 📦 Shrinkage of insulation (typical for new refrigerators).

If the noise does not decrease after 3 days, check whether the refrigerator is level and contact service.
