First launch of a refrigerator: 7 steps so as not to spoil the equipment from the first day

A new refrigerator is not just a purchase, but an investment in comfort for years to come. But even the most reliable model Samsung, LG or Atlant can fail in the first days if it is not connected correctly. Errors during the first start cause 18% of breakdowns during the warranty period - this is what service centers say. And this is not surprising: from skewed housing to premature loading of products - little things that are rarely paid attention to often lead to expensive repairs.

In this article - step-by-step algorithm for the first launch, which takes into account the nuances of different types of refrigerators (compressor, inverter, with system No Frost), as well as common mythsthat interfere with proper operation. You will learn why you should not turn on the refrigerator immediately after delivery, how to check the tightness of the seal, and exactly when you can load food. And also - what to do if, after starting, the equipment makes unusual sounds or does not cool down.

Spoiler: even if the instructions say “wait 2 hours before turning on”, for some models with an oil compressor this is not enough - up to 12 hours of vertical settling are required. More on this and other nuances below.

1. How long should the refrigerator sit before turning it on for the first time?

The most common mistake is to turn on the refrigerator immediately after delivery. In the transport position (especially lying on its side), the oil from the compressor spreads through the pipes of the cooling system. If you start the equipment ahead of time, the compressor will run “dry”, which will lead to its overheating and breakdown.

Here are the exact recommendations for standstill time depending on the type of refrigerator:

• 📦 Classic compressor models (Indesit, Beko, Biryusa): at least 4-6 hours in a vertical position. If the refrigerator was transported lying down, increase the time to 8–12 hours.
• ⚙️ Inverter compressors (Samsung Digital Inverter, LG Smart Inverter): 2–3 hours is enough, since the oil is distributed more evenly in them.
• ❄️ Models with the No Frost system: at least 6 hours - due to the complex air duct system.
• 🚛 If transportation took more than 12 hours (for example, intercity delivery): increase the standing time to 18–24 hours regardless of the type.

Why such differences? In inverter compressors, oil circulates even when the power is turned off due to a special design. And in systems No Frost additional time is needed to stabilize the pressure in the air ducts.

⚠️ Attention: If the refrigerator was transported at a temperature below +5°C (for example, in winter), before turning it on, it must stand in a warm room for at least 12 hours. Otherwise, condensation inside the system may freeze and damage the capillary tubes.

2. Preparing for the first start: check before turning on

Before inserting the plug into the socket, perform 5 mandatory checks. This will take 10 minutes, but will save you from 70% of typical problems:

Make sure that the refrigerator is level (check with a building level)

Check the integrity of the door seal (there are no gaps or damage)

Remove all shipping fasteners (staples, tapes, foam spacers)

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

Check the voltage in the outlet (should be 220–230 V ±10%)-->

Pay special attention shipping bolts - they secure the compressor during transportation. If they are not removed, you will hear a loud knocking noise when starting up, and the compressor may be damaged. In models Atlant and Stinol the bolts are usually located on the rear panel (see instructions). In Samsung and LG plastic clamps inside the camera are often used - they also need to be removed.

How to check the evenness of the installation without a level? Place a glass of water half full on the top lid of the refrigerator. If the water is distributed evenly, the equipment is positioned correctly. If there is a tilt, adjust the legs (in modern models they have threads to adjust the height).

⚠️ Attention: If you bought the refrigerator secondhand or it was stored in a warehouse for more than 6 months, before turning it on for the first time replace filter drier (part cost - from 500 ₽). Over time, it becomes saturated with moisture, which leads to corrosion of the system.

3. First launch: step-by-step instructions

Now that everything is prepared, you can turn on the refrigerator. Follow this algorithm:

1. Connect the refrigerator to the outlet. Use a separate line if the power of the equipment exceeds 1 kW (indicated in the passport). Do not connect via an extension cord!
2. Set the initial temperature. For most models, it is optimal:
   • 🥶 Refrigerator compartment: +4°C
   • ❄️ Freezer: –18°C

In electronically controlled refrigerators (Bosch, Liebherr), the temperature is set via the menu Settings → Temperature. In mechanical ones (Biryusa, Nord) - with a rotary control (usually position "3" out of 5).

Close the door and wait for the first cooling cycle. It lasts from 30 minutes to 2 hours, depending on the model. At this time, the compressor runs continuously - this is normal.

Check the operation of the fan (for No Frost). Put your ear to the back wall: you should hear a uniform sound of air. If it is not there, there may be a malfunction.

How do you know that the refrigerator is ready to load food? Pay attention to:

• 🔄 Compressor operating cycle: it should automatically turn off after cooling (you will hear the relay click).
• ❄️ Education frost: a thin crust of ice should appear on the back wall in the freezer (except for models No Frost).
• 🌡️ Temperature: use a separate thermometer to check. In the refrigerator compartment it should be +4...+6°C, in the freezer - -16...-18°C.

4. When can you load food?

This is the most common question after purchase. indoors:

• ⏳ Compressor models without No Frost: minimum 4-6 hours after the first shutdown of the compressor. If the room is hot (>25°C), increase the time to 8 hours.
• ❄️ No Frost and inverter compressors: can be loaded 2-3 hours after the first cycle, as they reach the operating mode faster.
• 🥩 Meat, fish, dairy products: they should be added last, when the temperature has stabilized. First, load bottles of water or canned food - they will help distribute the cold evenly.

Why can’t you load the products right away? During the first hours of operation, the temperature in the chambers is unstable. If you put warm food (for example, just purchased meat), the compressor will work without stopping, which will lead to:

• overheating of the motor windings,
• formation of condensation on the seal,
• uneven cooling (in some areas there may remain +10…+12°C).

How to speed up the process? If you urgently need to cool food:

1. Lay them in one layer on the shelves (do not place them tightly).
2. Use modes Super Cool or Express Freeze (if available).
3. Do not open the door first 2 hours after loading.

5. Typical mistakes during the first start (and how to avoid them)

The experience of service centers shows that 60% of breakdowns in the first month of operation are associated with five errors. Here they are - and how to prevent them:

1. Ignoring the settling time.

   Consequences: the oil does not have time to drain into the compressor, which leads to it jamming (repair cost - from 5,000 ₽).

   Solution: always wait at least 4 hours, even if the instructions indicate 2.

2. Connect via an extension cord.

   Refrigerators with inverter compressors (Samsung, LG) are sensitive to voltage surges. An extension cord without grounding can cause insulation breakdown.

   Solution: use a grounded outlet or stabilizer.

3. Loading hot products.

   Sharp temperature changes lead to icing of the evaporator and malfunctions No Frost.

   Solution: cool the food to room temperature before storing.

4. Incorrect installation.

   If the refrigerator is crooked, the door warps, and the seal allows warm air to pass through. This increases energy consumption by 25–30%.

   Solution: use a level and adjust the legs.

5. Ignoring transport fastenings.

   In 15% of cases this leads to damage to the compressor already in the first day.

   Solution: check the instructions - it shows where to look for bolts and fasteners.

Another common problem is incorrect placement of products. For example, if ice blocks in the freezer block the ventilation holes (in models No Frost), this leads to:

• uneven cooling,
• increased load on compressor
• ice formation on the walls.

What will happen if you turn on the refrigerator immediately after delivery?

If the oil does not have time to drain into the compressor, the engine will run dry when starting. This leads to:

- overheating of the windings (you can hear a characteristic burning smell),

- an increase in current consumption by 2-3 times,

- jamming of the compressor piston.

In 80% of cases, such a compressor is not subject to repair - requires replacement (cost - 30–50% of the price of the refrigerator).

6. Which sounds are normal and which are not?

In the first 24 hours, the refrigerator may make unusual sounds. Here's what is considered normal, and what should alert you:

If you hear constant gurgling (does not stop after 2-3 hours), this may indicate:

• 🔧 Clogged filter drier (needs replacement),
• 💧 Moisture entering the system (needs to be vacuumed and refilled refrigerant),
• 🌡️ Thermostat malfunction (the compressor runs non-stop).

In models with No Frost pay attention to the sound of the fan. If it:

• 🔇 disappears for 5-10 minutes, then appears again is normal (defrosting mode),
• 🔊 becomes louder with time - perhaps the blades are touching the ice or the body (defrosting is required).

7. The first day of operation: what needs to be monitored?

Within 24 hours after startup, monitor the following parameters:

• 🌡️ Temperature in the chambers: measure with a thermometer every 4-6 hours. In the refrigerator compartment it should stabilize at +3...+5°C, in the freezer - -18°C.
• ⏱️ Compressor operating cycles: normally it should work for 15–20 minutes, then turn off for 30–40 minutes. If the compressor does not turn off for more than 2 hours, this is a sign of a malfunction.
• 💧 Condensation: a small amount of moisture on the back wall of the refrigerator compartment (in models without No Frost) is normal. But if water accumulates under the fruit boxes, check the drain hole.
• 🔌 Energy consumption: in the first day it may be higher than usual (up to 1.5–2 kWh). If after 48 hours the flow rate has not decreased, there may be a refrigerant leak.

What to do if after 24 hours the temperature in the chambers has not stabilized?

1. Check that the door is tightly closed (use a piece of paper - if it pulls out easily, the seal is not airtight).
2. Make sure that the refrigerator is not located near heat sources (radiator, stove, direct sunlight).
3. If the model is with No Frostcheck that the ventilation holes are not blocked by food.
4. In mechanical refrigerators (Biryusa, Nord), try increasing the thermostat position by 1 notch.

⚠️ Attention: If an electronically controlled refrigerator (Bosch, Liebherr) shows an error (for example, E1, F2), do not try to reset it manually. Contact a service center - self-diagnosis may indicate a serious malfunction (freon leak, sensor failure).

8. Additional settings for optimal performance

Modern refrigerators offer features that many do not use, although they save energy and extend the life of the equipment. Here's what you should set up in the first days:

• 🌙 Holiday Mode: if you are leaving for 1-2 weeks, turn on this mode. The refrigerator will maintain a temperature of +12...+15°C, which will save up to 40% energy.
• 📱 Smart control: in models Samsung Family Hub or LG ThinQ you can connect the refrigerator to Wi-Fi and control the temperature from smartphone.
• 🔄 Automatic defrosting: in refrigerators with No Frost it occurs once every 10-12 hours. If you notice that the interval has increased, check the evaporator for the presence of ice.
• 🌡️ Freshness zones: in models with a separate zone Fresh Zone (0...+1°C) store meat, fish and herbs - they will stay fresh longer.

How to set up a freshness zone? In refrigerators Liebherr i Bosch it is regulated by a separate slider or button BioFresh. Optimal temperature for:

• 🥩 meat and fish: +1...+2°C,
• 🥬 greens and vegetables: +4...+6°C,
• 🧀 cheeses: +7...+9°C.

If your refrigerator supports Adaptive cooling (for example, technology Twin Cooling Plus v Samsung), it automatically adjusts the temperature depending on the load. But for accurate operation, the sensors must be clean - wipe them once every 2-3 months with a dry cloth.

FAQ: Answers to frequently asked questions

Is it possible to turn on the refrigerator while lying on its side?

No! In this position, oil from the compressor enters the cooling circuit. If the refrigerator has already been transported lying down, it must stand at least 12 hours in an upright position before turning it on. The exception is models with inverter compressor (for example, LG Inverter Linear), 4-6 hours are enough for them.

Why does a new refrigerator make a loud noise at first? hours?

This is normal: the compressor operates at maximum power to cool the chambers. The humming should subside after 2-3 hours. If the noise does not decrease or vibration appears, check:

• whether the transport bolts have been removed,
• whether the refrigerator is level (adjust the legs),
• whether the back wall of the furniture is touching (there should be a gap of 5–10 cm).

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

Yes, but without aggressive detergents. It is enough to wipe the internal surfaces with a soda solution (1 tablespoon per 1 liter of water) or a special product for refrigerators (for example Topperr or Sano Refrigerator Cleaner). Do not use bleach or vinegar - they can damage the plastic and leave an odor.

What to do if the refrigerator does not cool after starting?

Check:

1. Is the refrigerator connected to the outlet (the power indicator should burn).
2. Has the The safety thermostat worked (in some models it turns off the power when overheated).
3. Are the ventilation holes blocked (in models No Frost).
4. Temperature indoors - if it is below +16°C, the compressor may not turn on.

If everything is in order, but the refrigerator does not freeze, call a technician - it is possible refrigerant leak or a compressor malfunction.

Can I use extension cord for a refrigerator?

Only if it meets two conditions:

• 🔌 Has grounding and is designed for a current of at least 10 A.
• 📏 Length cable does not exceed 1.5 m (the longer the extension cord, the higher the voltage loss).

It is best to connect the refrigerator directly to the outlet. If this is not possible, use surge protector (for example, APC SurgeArrest).
