New refrigerator after the first turn on: how long should it work and why it important

You just purchased a new refrigerator, installed it in the kitchen, connected it to the network - and now you watch in awe as it starts up. But how long should it work without stopping? Is it normal for the compressor to not turn off for hours? Or, conversely, did the unit “quiet” too quickly - is this a sign of a malfunction?

These questions concern everyone who is faced with turning on the equipment for the first time. Especially if we are talking about an expensive model with a system No Frost or an inverter compressor. In this article we will understand Why can a new refrigerator work from 2 to 24 hours in a row when first started?what factors influence this, and when you should really sound the alarm. We will also give a checklist of actions so that your unit will serve for many years without breakdowns.

Why does a new refrigerator work for a long time when first turned on?

The first start is always a stress test for equipment. Even if you bought a refrigerator Liebherr or Samsung with a factory warranty, its systems need time to “get used to” the new conditions. Here are the main reasons for long-term operation:

• 🔹 Factory preservation. Often particles of oil or technical gases remain inside the chambers, which disappear only after several cycles of operation. This is normal - manufacturers deliberately do not remove them completely in order to protect the parts during transportation.
• 🔹 Temperature set. The refrigerator needs to cool not only the air, but also all internal surfaces, shelves, and sometimes food, if you have already loaded it. In an empty unit, the process goes faster.
• 🔹 Compressor adaptation. Modern inverter models (for example, LG Inverter Linear Compressor) work at increased power for the first hours in order to quickly reach the optimal mode.
• 🔹 Thermal inertia. If the refrigerator was in an unheated warehouse or was delivered in winter, its parts could cool to a temperature below +10°C. At room temperature (+20...+25°C) this creates an additional load.

Interesting fact: in the instructions for refrigerators Bosch and Indesit it is directly stated that the first cycle of operation can take up to 12–18 hours —and this is not a cause for concern. The main thing is that the equipment does not turn off before 2 hours (this may indicate a malfunction of the thermostat or a freon leak).

How long a refrigerator should work when first turned on: standards by type

Time continuous operation depends on cooling system type, the volume of the chambers and even the climate class (indicated on the sticker on the back). Below are averaged data for popular models. Please note: figures may vary by ±20% depending on room temperature.

⚠️ Attention: If your refrigerator turned off before 2 hours, check if the mode Demo or Eco is turned on (sometimes they are activated in the store). These functions limit the compressor power and the equipment cannot cool properly. How to turn it off: hold down the button Super Cool or Holiday for 5-10 seconds (the exact combination is indicated in the instructions).

Make sure that the refrigerator is level (adjustable legs)

Check the gap between the wall and the back panel (minimum 5 cm)

Disable Demo/Eco mode (if available)

Do not load food in the first 2-3 hours

Control the temperature after 6 and 12 hours-->

5 errors that lengthen the first cycle of operation

Sometimes the refrigerator works longer than normal not because of the features of the model, but because incorrect user actions. Here are the most common mistakes:

1. Loading warm products. If you put freshly cooked soup or hot semi-finished products into the chamber, the compressor will have to waste energy cooling them. Optimal: wait until the food cools down to room temperature.
2. Frequent opening of doors. Every time you check how it is inside, warm air enters the chamber. On the first day, try to open the refrigerator no more than once every 2 hours.
3. Incorrect installation. If the appliance is located close to the wall or radiator, the rear grille overheats and the compressor cannot turn off in time. Minimum indentations: 5 cm at the back, 2 cm at sides.
4. High room temperature. At +30°C in the kitchen, the refrigerator will work 30–50% longer. If your model has a climate class SN-T (for the tropics), the problem is less pressing.
5. Overloading the freezer. If you immediately filled the freezer with meat to capacity, the compressor will take up to 24 hours to reach -18°C.

💡 Useful advice: To speed up the first cycle, place 2-3 bottles of cold water (from the tap) in an empty refrigerator. They will help to quickly reduce the temperature inside the chambers. But do not put ice - a sudden change can cause condensation on the seal.

What to do if the refrigerator has been running for 30+ hours?

If the equipment does not turn off for more than a day, check:

1. Room temperature — when +35°C and above, some models physically cannot reach normal mode.

2. Door closing tightness — place a sheet of paper between the seal and the body. If it falls out, the hinges need to be adjusted.

3. Thermostat settings —in some refrigerators (for example, Atlant) the default value is –24°C in the freezer. Reduce to –18°C.

4. Presence of freezing —if ice appears on the back wall of the drip refrigerator, a freon leak may occur.

If all else fails, call a technician. But in 80% of cases, the problem is solved by adjusting the operating conditions.

How to understand that the refrigerator has returned to normal mode?

Some users wait until the compressor turns off for the first time, and consider this a sign of “readiness”. But this is not entirely true. Here 3 reliable signalsthat the equipment works stably:

• 📉 Cyclicity. The refrigerator turns off for 10-20 minutes, then turns on again. The intervals between starts are approximately the same (for example, 30 minutes of work / 15 minutes of rest).
• ❄️ Temperature. In the main chamber it stays at +4...+5°C, in the freezer -18°C (check with a thermometer, not on the display - it can lie!).
• 🔊 Sound. The compressor operates quietly, without any extraneous knocks or vibrations. For inverter models (Hitachi, Panasonic) the sound is almost inaudible.

⚠️ Attention: If after the first shutdown the refrigerator turns on again after 5-10 minutes and works without pauses, this is a sign faulty thermostat or a sensor. In this case, you need to urgently contact a service center before the compressor burns out.

For precise control, use external thermometer (for example, Xiaomi Mijia with Bluetooth). Place it in the center of the main camera at 12 o'clock. If the temperature fluctuates within ±1°C, everything is fine. If the spread is more than 3°C, diagnostics is required.

What to do first 24 hours: step-by-step instructions

To ensure that your new refrigerator lasts for many years, follow this algorithm on the first day of operation:

1. 0–2 hours: Do not open the door, do not load food. Allow the equipment to adapt to the room temperature.
2. 2–6 hours: Check whether condensation has appeared on the seal. If yes, wipe with a dry cloth. You can put a bag of silica gel in the chambers (it will absorb excess moisture).
3. 6–12 hours: Load products, but no more than 50% of the volume. Distribute them evenly on the shelves so as not to block the ventilation holes (in models No Frost).
4. 12–24 hours: Adjust the temperature: +4°C for the refrigerator, -18°C for the freezer. Turn on the mode Super Freeze for 2–3 hours if you have loaded a lot products.

🔧 Technical nuance: In refrigerators with electronic control (Samsung RB, LG Instaview), after the first switching on, autodiagnosisa flashing indicator or inscription will appear on the display IF (Ice Fan) - this is normally. Wait for the process to complete (usually 10–15 minutes).

When to sound the alarm: signs of malfunction

In most cases, long work when first turned on is the norm. But there is 5 alarm signalsthat require intervention:

⚠️ Attention: If the refrigerator Beko or Gorenje with the system NeoFrost works without stopping and ice forms on the back wall, this is not "transition period", and a sign clogged drain hole. Clean it with a cotton swab dipped in warm water, otherwise water will accumulate under the drawers.

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

Is it possible to immediately load food into a new refrigerator?

Not recommended. In the first 2-4 hours, it is better to let the appliance cool in an empty state. If you urgently need to put perishable foods (for example, meat), distribute them on one shelf without closing the ventilation holes. Do not load the freezer to more than 30% of the volume.

Why the new refrigerator No Frost works quieter than the old one?

Modern models are equipped with soundproofed compressors and improved ventilation. For example, in refrigerators Samsung Twin Cooling Plus the noise level does not exceed 37 dB (as in a library). If you are used to the loud operation of the old unit, the new equipment may seem “suspiciously quiet.” This is normal. data-i="219">noise-insulated compressors

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

Yes, but without aggressive detergents. Wipe the internal surfaces with a soft cloth soaked in a solution of baking soda (1 tablespoon per 1 liter of water). seal - particles of factory lubricant often remain on it. Do not use abrasives or alcohol solutions: they can damage the antibacterial coating (for example, BioFresh in models Liebherr).

How much electricity does the refrigerator consume on the first day?

On the first day, the consumption may be 1.5–2 times higher than the rated value. For example, if the specifications indicate 300 kWh/year (≈0.8 kWh/day), when you first turn on the equipment, it will “eat” up to 1.5 kWh. This is due to the long-term operation of the compressor. From the second day, the consumption will be normalized.

Can it be transported? refrigerator after the first start-up?

Absolutely not! After starting, the compressor and oil in the system heat up. If you transport the refrigerator in a horizontal position, the oil will enter the cooling circuit and may clog the capillary tube. Minimum interval between switching on and transportation - 48 hours. Before transporting the equipment, you must turn it off and let it stand for 6 hours in a vertical position. position.
