You opened the instructions for the new refrigerator, came across a mysterious button Action Cool —and now you are wondering why it is needed? Or maybe your old unit suddenly began to make a loud noise, and this same one lights up on the display, but it’s not clear what to do with it? Don’t rush to panic: this is not a breakdown, but a useful feature that many users are not even aware of. Action Cool, but what to do with it is unclear? Don’t rush to panic: this is not a breakdown, but a useful feature that many users don’t even know about.
Mode Action Cool (sometimes called Power Cool, Fast Cool or Turbo Cool depending on the brand) is a fast cooling technology that is useful in a variety of situations: from preparation to big feast until the temperature returns after a power outage. In this article, we will look at how it works at the physical level, when it is worth activating it, and when it is better to do without it, and why some models of refrigerators automatically turn on Action Cool when the door is opened for more than 30 seconds are not a bug, but a feature!
You will also learn how to properly use this function on refrigerators Samsung, LG, Bosch and other popular brands, what mistakes owners most often make, and why abuse of “turbo mode” can lead to an increase in electricity bills by 15–20%. Spoiler: it's all about the compressor and fan!
What is Action Cool: a simple explanation at your fingertips
Imagine: you brought three bags of groceries from the store, including hot soup in a pan, fresh meat and ice cream. If you simply put it all in the refrigerator, the temperature inside the compartments will rise, and some foods may spoil before they even cool down. This is where it comes to the rescue Action Cool.
In normal mode, the refrigerator maintains the set temperature (for example, +4°C in the main chamber), turning on the compressor periodically. But Action Cool forces the system to work at maximum power:
- 🔄 The compressor goes into continuous operation mode (or with minimal pauses).
- ❄️ Fans (if they are in the model) rotates at an increased speed, evenly distributing the cold.
- ⏱️ Temperature falls to the lowest possible level (usually 2–4°C below standard).
- ⚡ Energy consumption increases by 1.5–2 times compared to normal mode.
Simply put, it’s like “turbo mode” in a car: when you need to accelerate quickly, the engine works at the limit, but you can’t drive like that all the time - otherwise wear will increase. Likewise Action Cool useful in the short term, but not intended for constant use.
How Action Cool works: technical details
To understand why this mode is so effective, let’s figure out what happens inside the refrigerator at the physical level. It's all about three key systems:
- Compressor —the “heart” of the refrigerator. In Action Cool mode it works without stopping or with minimal pauses (1-2 minutes instead of the usual 10-15). This allows heat to be removed from the chambers faster.
- Evaporator — here the refrigerant (freon) boils, absorbing heat. In accelerated mode, the circulation of freon increases, and the evaporator cools more intensively.
- Fans (in models with the system No Frost). They drive cold air through the chambers, eliminating “warm zones”. In normal mode, the fans turn on periodically, but here they work constantly.
Interesting fact: in refrigerators with Inverter compressor (for example, Samsung Digital Inverter or LG Smart Inverter) the transition to Action Cool happens more smoothly, without sudden voltage surges. But in models with a conventional linear compressor, you may hear a louder noise - this is normal.
| Parameter | Normal mode | Action Cool mode |
|---|---|---|
| Temperature in the main chamber | +4…+5°C | +1...+2°C (or lower) |
| Compressor operating time | Cycles (10–15 min work / 5–10 min pause) | Continuously or with pauses of 1–2 minutes |
| Fan speed | Low/medium | Maximum |
| Energy consumption | 0.5–1 kWh/day | 1.2–1.8 kWh/day |
| Noise level | 35–45 dB | 45–55 dB |
Important: in some models (for example, Bosch Serie 6 or Liebherr Premium) Action Cool automatically turns off after 6-12 hours to prevent system overload. In others (for example, Samsung RBit must be turned off manually.
When to turn on Action Cool: 5 practical cases
Many users mistakenly think that this mode is only needed for quickly cooling drinks. In fact, the scope of its application is much wider. Here top 5. situationswhen Action Cool really saves:
- 🍗 Loading a large volume of warm products. Have you brought a bag with purchases after shopping? Turn on the mode for 1-2 hours so that the temperature in the chamber does not rise above +5°C.
- ⚡ Recovery after a power outageIf the light has been turned off for more than 30 minutes, data-i="132">will help you quickly return to the desired temperature (especially important for freezers). Action Cool will help you quickly return to the desired temperature (especially important for freezers).
- 🎉 Preparation for holidayBefore a big feast, turn on the mode 3-4 hours in advance so that all dishes cool evenly and the ice cream does not melt.
- ☀️ Heat outside the window. If the room is more than +30°C, it is more difficult for the refrigerator to maintain cold. Action Cool compensates for external heat.
- 🧊 Frozen fresh foodDo you need to quickly freeze berries or greens? there).
And now - anti-rating: when Action Cool turn on not is worth:
- ❌ On an ongoing basis. The compressor wears out faster, and the electricity bill will increase.
- ❌ At nightThe noise level can interfere with sleep (especially in open rooms). kitchen studios).
- ❌ If the chamber is almost empty. There is no point in cooling the air - energy is wasted.
What happens if you forget to turn off Action Cool?
If you leave the mode on for a day or longer, the compressor will overheat, and the door seals may become deformed from the constant cold. In the worst case, the thermal protection will work and the refrigerator will turn off before it cools down. In models with a display, an error may appear E1 or F5 (system overload). data-i="157">How to turn Action Cool on and off: step-by-step instructions
How to turn Action Cool on and off: step by step instructions

⚠️ Attention: In refrigerators with two compressors (for example, Samsung Twin Cooling Plus) Action Cool can work separately for the refrigerator and freezer compartments. Make sure you have activated it in the right compartment!
Action Cool vs Super Freeze: what is the difference?
Many people confuse Action Cool with another popular mode - Super Freeze (or Express Freeze) These are actually two different functions, although both are designed for accelerated cooling. Here are the key differences:
| Parameter | Action Cool | Super Freeze |
|---|---|---|
| Purpose | Fast cooling refrigerator compartment | Fast freezing in freezer compartment |
| Temperature | Decreases by 2–4°C from standard | Decreases to -24...-30°C |
| Operating time | Usually 1–6 hours | From 24 to 72 hours |
| Typical scenarios | Cooling drinks, large loads of food | Freezing fresh berries, meat, semi-finished products |
In some models (for example, LG Instaview) these modes can be turned on simultaneously, but this puts a colossal load on the compressor. It is better to use them separately, with a break of at least 1-2 hours.
Common mistakes and how to avoid them
Even experienced users sometimes make mistakes when using Action CoolHere are the most common ones - and how not to repeat them:
- 🔌 Turn on the mode with the door open.. The refrigerator will try to cool the entire kitchen! Close the door tightly.
- ⏳ Forget to turn it off.. Some models do not have an automatic shutdown. Set a reminder on your phone.
- 🍎 Place the products close to the back wall. This blocks air circulation. Leave a gap of 2-3 cm.
- ❄️ Use for defrosting freezers. Action Cool does not replace
Super Freezeand does not speed up thawing. - 🔊 They panic because of the noise. In this mode, the refrigerator operates louder - this is normal.
Another typical problem: users complain that after Action Cool ice forms on the back wall of the refrigerator. if:
- There is high humidity in the chamber (for example, soups or fruits that have not cooled down).
- The door is not closed tightly (check the seal).
- The mode worked for too long (more than 6-8 hours).
⚠️ Attention: If after shutdown Action Cool the refrigerator does not return to normal temperature within 2-3 hours, this may indicate a malfunction of the thermostat or sensor. In this case, you should call a technician.

FAQ: Answers to frequently asked questions
Can Action Cool be turned on all night?
Not recommended. Maximum - 6-8 hours in a row. Long-term operation in this mode increases wear on the compressor and energy consumption. If you need to maintain a low temperature for a long time (for example, in hot weather), it is better to reduce the standard temperature by 1-2°C. manually.
Why does the refrigerator not cool after Action Cool?
Probable reasons:
- The compressor has overheated - let it cool for 1-2 hours.
- Thermal protection has tripped - unplug the refrigerator for 10 minutes, then turn it on again.
- The temperature sensor is faulty - diagnostics are required.
If the problem persists, call a technician.
How often can you use Action Cool?
Optimal - no more than 2-3 times a week For intensive use (for example, every. day) the compressor wears out faster, and door seals may lose elasticity due to temperature changes.
Is there Action Cool in Indesit and Atlant refrigerators?
