How long does the refrigerator work when you first turn it on - norms and possible problems

You just bought a new refrigerator, connected it to the network - and it started working without stopping. Is this normal? How long does must function continuously the unit last for the first time before it shuts down? These questions concern every owner of new equipment. The answer depends on the model, the room temperature and even on how you prepared the refrigerator for operation.

In this article we will figure out why first turn on is always a stress test for equipment, what parameters are considered normal for different types of refrigerators (compressor, inverter, No Frost), and what to do if the unit works too long or, conversely, turns off too quickly. You will also learn how to properly prepare the refrigerator for the first start in order to avoid typical mistakes that lead to breakdowns.

Why does the refrigerator work without stopping when you turn it on for the first time?

When starting for the first time, the refrigerator faces a problem cool the entire internal space —from empty shelves to door seals. Unlike the usual mode, when the equipment maintains the set temperature, here it is required maximum power to reduce the temperature from room (20–25°C) to working (usually +4...+5°C in the refrigerator and −18°C in the freezer).

Here are the key reasons for long-term operation:

• 🔹 Compressor heating —at the first start, the oil in the system is still cold, and the motor requires more effort to pump the refrigerant.
• 🔹 Lack of “cold stock” —in new refrigerators there is no residual cold (unlike the former use).
• 🔹 Thermal insulation of materials —plastic parts, seals and even metal elements are first heated and then cooled.
• 🔹 Automatic diagnostics —modern models (for example, Samsung RB37A52 or LG GB-B459SLQZ) can test systems before switching to normal mode.

In addition, if the refrigerator was transported in a horizontal position (which is strictly not recommended), oil from the compressor could get into the cooling circuit. In this case, the first turn on will take 30–50% longer, since the system will have to “push” the oil back.

Norms of operating time when first turned on for different types of refrigerators

Continuous operating time depends on compressor type, cooling system and chamber volume. Below is an approximate range for popular models:

If your refrigerator runs longer than the specified standards, this is not always a reason to panic. For example, in a hot room (above 30°C), the first cycle time may increase by 2–3 hours. But if the unit does not turn off for more than 24 hours is a clear sign of a malfunction (more about this in the diagnostics section).

How to properly prepare the refrigerator for the first start-up?

Many breakdowns during the first start occur due to improper preparation. Here are step-by-step instructions that are often overlooked:

Unpack and remove all shipping fasteners (staples, tapes, foam)

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

Check the door seals for damage

Install the refrigerator on a flat surface (check with a level!)

Connect to a separate outlet (without extension cords!)

Wait at least 2-4 hours before turning on (to stabilize the oil in compressor)-->

Pay special attention transport bolts —if they are not removed, the compressor may fail within the first hours of operation. In models ATLANT and Indesit the bolts are usually located on the rear panel, in Samsung and LG - under the bottom cover.

Also check if anything overlaps ventilation grilles (especially important for models No Frost). The gap between the wall and the refrigerator should be at least 5 cm at the back and 2–3 cm at the sides. Otherwise, the compressor will overheat, and the first cycle time will increase by 1.5–2 times.

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

If the refrigerator was transported lying down or at an angle, oil from the compressor could get into the circuit. If turned on immediately, this will lead to water hammer - one of the most common causes of failure of new compressors. Symptoms: humming without cooling, automatic shutdown after 1–2 minutes, errors on the display (for example, E1 or F2 in models Beko).

When is long-term operation when first turned on the norm, and when is it a cause for concern?

Let's figure out in what cases long work is a normal situation, and when to sound the alarm.

✅ Normal situations:

• 🌡️ The temperature in the room is higher 30°C (the refrigerator takes longer to get cold).
• ☀️ Direct sunlight hits the body (especially important for built-in models).
• 📦 The refrigerator is loaded with warm food immediately after turning on.
• ❄️ Mode Super Freeze or Fast Cool activated (in some models it turns on automatically).

❌ Requires diagnostics:

• ⏳ Works without stopping more than 24 hours at room temperatures up to 25°C.
• 🔥 The case gets very hot (hot to the touch, especially at the bottom at the back).
• 💨 The fan No Frost does not turn off or makes strange sounds.
• ⚠️ An error appears on the display (for example, H1 y Liebherr is a problem with the sensor).

Pay attention to the soundssounds made by the refrigerator. Normal noises when first turned on:

• 🔊 Light gurgling - refrigerant circulation.
• 🔊 Crackling - thermal expansion of plastic.
• 🔊 Periodic clicking is the activation of the compressor relay.

But a constant hum without pausesrattling or grinding is a reason to turn off the refrigerator and call a technician.

What to do if the refrigerator runs for too long or does not turns off?

If more than 12 hours have passed and the refrigerator still does not turn off, perform step-by-step diagnostics:

1. Check room temperature. If above 30°C, give the refrigerator additional time (up to 18–24 hours).

2. Make sure that the door is tightly closed. Place a sheet of paper between the seal and the body - if it falls out, the seal is broken.

3. Turn off the modes Super Cool/Super Freeze (if any). In some models (Bosch KAN92VI30R) they are activated automatically the first time you turn them on.

4. Check temperature settings. Optimal values ​​for the first start: refrigerator compartment +4°C, freezer −18°C. If you set to −24°C, the compressor will run longer.

5. Inspect rear wall. If it is covered with frost (in models without No Frost), this is normal. If condensation flows down in a stream, there may be a refrigerant leak.

If after these steps the refrigerator still does not turn off, unplug it from the outlet for 1-2 hours, then turn it on again. If the problem repeats, it may be:

• 🔧 Malfunction thermostat (a common problem in ATLANT and Stinol).
• 🔧 Blockage capillary tube (typical for refrigerators older than 5 years).
• 🔧 Breakage start relay compressor.

How long should the refrigerator operate after the first one? shutdown?

After the refrigerator turns off for the first time, it goes into cyclic mode. Normal operating parameters:

• 🕒 Operating time: 10–20 minutes.
• ⏱️ Rest time: 20-40 minutes.
• 🔄 Work/rest ratio: 1:2 or 1:3 (depending on the model).

In the first 2-3 days, the cycle may be unstable - this is normal, since the technique “adapts” to the conditions. refrigerator for a week:

• 🔴 Runs for more than 30 minutes and rests for less than 10 minutes - compressor overload.
• 🔴 Turns off for 1-2 hours - insufficient power or freon leak.

This is a reason to check settings or call a technician.

For accurate diagnostics, use a household thermometer:

1. Place it in the refrigerator compartment on the middle shelf.
2. 2 hours after turning off the compressor, check the readings.
3. Norm: +3...+5°C. If above +7°C, the refrigerator cannot cope.

Frequent errors when first turned on and how to fix them. avoid

Even minor mistakes can lead to malfunctions or shortening the life of the refrigerator. Here's what cannot be done:

• ❌ Turn on immediately after delivery (risk of compressor water hammer).
• ❌ Load warm products in the first 4-6 hours (increases cooling time by 30-50%).
• ❌ Install nearby with heat sources (battery, stove, microwave).
• ❌ Ignore the transport bolts (leads to vibration and breakdown of the compressor).
• ❌ Connect via an extension cord (may not have enough power for starting current).

Also, many people forget about ventilation. data-i="234">🔸 Back: 5–10 cm.. For example, if a refrigerator No Frost is built into a furniture module without gaps, the fan will wear out and the compressor will overheat. Minimum gaps:

• 🔸 Back: 5–10 cm.
• 🔸 On the sides: 2–3 cm.
• 🔸 Top: 5 cm (if the model has top ventilation).

Another common mistake is incorrect temperature setting.. Many people set the maximum cold (−24°C in the freezer), believing that this will speed up cooling. In fact, this leads to:

• 🔹 Increase the time of the first cycle by 2-4 hours.
• 🔹 Compressor overload (especially in inverter models).
• 🔹 Formation of excess ice in the freezer (frequent defrosting will be required).

FAQ: Answers to frequently asked questions about turning on the refrigerator for the first time

❓ The refrigerator has been running for 12 hours without stopping - is this normal?

For models No Frost and large refrigerators (with a volume of 300 liters or more), this may be the norm, especially if the room is hot. Check the temperature inside: if it gradually decreases, wait a little longer. 6–12 hours. If after 24 hours the refrigerator does not turn off, turn it off and call a technician.

❓ Is it possible to put food in the refrigerator immediately after turning it on?

It is not recommended. In the first 2–4 hours, the temperature inside is not yet stable, and the food may spoil. If you urgently need to cool something (for example, medicine), use it. mode Super Cool, but do not load the chamber completely.

❓ Why does the new refrigerator make a loud noise when you first turn it on?

This is normal: the compressor operates at maximum power, and the refrigerant circulates at high pressure. The hum should subside after the first shutdown. If the noise does not decrease after 24 hours, check whether it is smooth. is the refrigerator standing (adjust the legs) and is there any vibration from contact with the furniture.

❓ Is it necessary to defrost a new refrigerator before turning it on for the first time?

No, this is not only useless, but also harmful. Defrosting is only necessary for used refrigerators. dry chambers, and excess moisture can disrupt the operation of the system No Frost.

❓ What to do if the refrigerator turns off 5 minutes after turning it on?

This is a sign start relay malfunction or compressor jamming. Immediately unplug the refrigerator and do not turn it on again - this may lead to a short circuit. Call a technician for diagnostics.

If your case is not described in the FAQ, contact service center indicating refrigerator models and symptoms. Most manufacturers (ATLANT, Indesit, Samsung) provide a guarantee for the compressor for up to 5-10 years, but only if the rules for the first start are observed.
