The first switching on of a new refrigerator is a crucial moment on which not only the service life of the equipment depends, but also the safety of the products stored in it. Many users are wondering: how long does it take for a refrigerator to gain coldwhen was it just connected to the network? The answer is not as clear-cut as it might seem. The cooling time depends on the model, volume, type of system (No Frost or drip), room temperature and even on whether the refrigerator is loaded with food.
In this article we will figure out what factors influence the rate of cold gain, we will provide real timing for different types of refrigerators (from compact to Side-by-Side), and also give practical advice on how to speed up the process and avoid typical mistakes. If you have just purchased equipment or are planning to install it, this information will help save time and nerves.
Why does it take longer to turn on the refrigerator for the first time?
When first started, the refrigerator operates in non-standard conditions. Unlike the usual mode, when the equipment maintains the set temperature, here the task is more complicated:
- 🔹 Heating of the compressor and oil. In a new refrigerator, the oil in the compressor is cold and thick, which creates additional load on the engine. The first cycles of operation may be less efficient.
- 🔹 Lack of “cold reserve”. Unlike a refrigerator that was already working, the new one does not have accumulated cold in the evaporator and walls.
- 🔹 Heat exchange with the environment. The body of the refrigerator heats up during transportation, and the internal surfaces are at room temperature.
In addition, modern refrigerators are often equipped adaptive cooling systemswhich work in enhanced mode for the first hours, analyzing the conditions. For example, models Samsung Twin Cooling Plus or LG InstaView can spend up to 12–15 hours on primary temperature stabilization if the volume of the chambers is large (more than 300 l).
How long does it take to get cold: data for different models
The cooling time of the refrigerator when first turned on varies from 2 to 24 hours. Below is a table with approximate deadlines for popular types of equipment. Please note that this average values real time depends on external conditions.
| Refrigerator type | Volume (l) | Cold accumulation time (hours) | Notes |
|---|---|---|---|
| Single-chamber (drip) | 100–150 | 2–4 | Cools quickly due to the small volume, but is less stable when the door is opened. |
| Double-chamber (No Frost) | 200–280 | 4–8 | The No Frost system requires additional time to blow through the evaporator. |
| Side-by-Side | 350–500 | 8–12 | Large volume and separate cooling zones increase the time. |
| Built-in (compact) | up to 100 | 1–3 | Minimal time, but sensitive to external temperature. |
| Chest freezer | 100–300 | 6–18 | Requires deep cooling to −18°C, time depends on load. |
For comparison: premium refrigerators (for example, Liebherr Premium or Bosch Serie 8) can gain cold faster thanks to inverter compressors and improved thermal insulation. At the same time, budget models (for example ATLANT XM 4021) often require 20-30% more time due to a less efficient cooling system.
Factors that accelerate or slow down cooling
The rate of cold gain is affected not only by the model of the refrigerator, but also by external conditions. Let's consider the key factors:
- 🌡️ Room temperature. The hotter the room, the longer the refrigerator will take to cool. At +30°C, the time may increase by 30–50%.
- 📦 Loading products. An empty refrigerator will cool faster than a full one. However you cannot load products immediately after switching on - this will disrupt the heat exchange.
- 🔌 Voltage stability. Voltage surges cause the compressor to work inefficiently, increasing cooling time.
- 🚪 The frequency of door opening. Each opening adds warm air, disrupting the process.
It is also worth considering type of refrigerant. Modern refrigerators use R-600a (isobutane) or R-134a, which differ in thermal conductivity. For example, R-600a provides faster cooling, but requires precise dosage when refilling.
What to do if the refrigerator takes too long to get cold?
If after 24 hours the temperature in the chambers has not reached normal (+5°C in the refrigerator and −18°C in the freezer), check:
1. Correct connection to the network (are there any problems with the socket or plug).
2. Temperature settings - the gentle mode may be set (Eco Mode).
3. Tightness of the door seals (attach a sheet of paper - if it falls out, the seal is worn out).
4. Fan performance (in No Frost models).
If the problem persists, contact a service center - a leak is possible refrigerant or compressor malfunction.
When can you load food after the first turn on?
One of the most common questions: after how long can you put food in a new refrigerator? A simple rule applies here:
- 🥛 Refrigerator compartment: no earlier than 2–3 hours after the temperature reaches +5°C (check on the display or thermometer).
- ❄️ Freezer compartment: no earlier than 4–6 hours (should be stable at −18°C).
The exception is refrigerators with function Super Cooling (for example, Beko ProSmart Inverter), which can cool to operating temperature in 1–1.5 hours. However, even in this case, it is not recommended to load food immediately - let the equipment stabilize.
⚠️ Attention: If you load warm or hot food into an uncooled refrigerator, this can lead to:
- 🔥 Overheating of the compressor and its premature wear.
- 🦠 Development of bacteria in products due to unstable temperatures.
- ❄️ Formation of ice in models without No Frost.
How to speed up the accumulation of cold: practical tips
If you need to the refrigerator has cooled down faster, use these recommendations:
Do not load food in the first 2-3 hours
Set the minimum temperature on the regulator
Ensure ventilation of the rear wall (move 5-10 cm from the wall)
Close the door and do not open unless necessary
Use the "Quick Cooling" function (if available)-->
Additionally, you can:
- 🧊 Place in the freezer ice packs or frozen batteries cold (if they are included).
- 🌬️ Turn on fan in the room, directing the air flow to the back wall of the refrigerator (but not to the compressor!).
- 🔧 Check whether demonstration mode (
Demo Modeis enabled, which simulates operation without real cooling.
In models with electronic control (for example, Samsung RB30A3200SA) you can activate the Power Cool or Fast Freezemode, which speeds up the operation of the compressor. However, do not keep it for more than 2-3 hours - this increases the load on the system.
Frequent errors when first turned on refrigerator
Many users unintentionally slow down the cooling process or even risk damaging the equipment. Let's look at typical mistakes:
- Switching on immediately after transportation. If the refrigerator was transported lying down (for example, in a car), oil from the compressor could get into the circuit. In this case, you need to wait 4–6 hours before turning it on so that the oil flows back.
- Ignoring instructions. Some models (for example Indesit DF 4180) require pre-setting of temperature zones through the menu.
- Connecting via an extension cord. This can cause a voltage drop, especially if the extension cord is of poor quality.
- Installation close to a wall or furniture. Air circulation is disrupted, which leads to overheating of the compressor.
Another common problem is improper installation of legs. If the refrigerator is not level, the door may not fit tightly, allowing warm air to enter. Check the level using a spirit level or an application on your smartphone.
⚠️ Attention: If you connect the refrigerator to generator or UPS, make sure that the device supports the starting currents of the compressor (they are 3-5 times higher than the rated ones). Otherwise, malfunctions may occur.
FAQ: Answers to popular questions
Is it possible to turn on the refrigerator immediately after delivery?
If the refrigerator was transported in a vertical position, can be turned on after 1–2 hours. If it was lying on its side, you need to wait 4–6 hours for the oil from the compressor to return to the crankcase. Ignoring this rule can lead to hydraulic hammer compressor breakdown.
Why does a new refrigerator make a loud noise in the first hours of operation?
This is normal: in a new refrigerator the compressor operates at maximum power, and the refrigerant circulates at increased speed. The hum should subside after 1-2 days when the temperature stabilizes. If the noise does not decrease or knocking appears, check fastening of the compressor and fan.
What to do if the refrigerator does not cool after 24 hours?
First check:
- Connection to the network (the machine or RCD may have tripped).
- Temperature settings (sometimes the default is +10°C).
- Door tightness (the seal could be deformed during transportation).
If everything is fine everything is fine, but the refrigerator does not freeze - call a specialist. Possible reasons: freon leak, malfunction of the compressor or temperature sensor.
Do you need to wash the refrigerator before turning it on for the first time?
Yes, but with reservations. Wipe the internal surfaces a soft cloth with soda solution (1 tablespoon of soda per 1 liter of water), then wipe dry. Do not use aggressive detergents - they may damage the plastic or leave an odor. Pay attention drainage hole (in drip models) so that it is not clogged with dust.
Is it possible to use a refrigerator without a stabilizer tension?
It is possible, but risky. Modern refrigerators with inverter compressors (LG Inverter Linear Compressor, Samsung Digital Inverter) are less sensitive to voltage surges, but strong surges (below 180 V or above 240 V) can damage the electronic board. If your network has frequent fluctuations, it is better to use voltage relay or a stabilizer.
