Modern refrigerators are equipped with many digital symbols and buttons whose meaning is not always obvious at first glance. One of these symbols, often found on control panels, is the inscription Cool Plus or its variations. Many users, when encountering this mode for the first time, wonder about its intended purpose and the need to activate it in everyday use.
In fact, this function is a mode intensive coolingthat allows you to quickly lower the temperature in the refrigerator compartment to the lowest possible values. This is not just a marketing name, but a full-fledged algorithm for the operation of the compressor, designed for emergency situations. Understanding the principle of operation of this mode will help you more effectively manage the safety of food and the energy consumption of your device.
In this article we will analyze in detail in what cases you should turn on Cool Plushow it affects the operation of the system No Frost or static cooling, and why its constant use may be unwanted. We will also look at the technical nuances of the compressor operating in this mode and give recommendations for the optimal operation of household appliances.
The principle of operation of the intensive cooling mode
Function Cool Plus (sometimes indicated as Cooling Plus or Power Cool v depending on the brand) forces the refrigerator compressor to maximum performance mode. Unlike the standard cycle, where the temperature is maintained in a given range with periodic engine stops, here the unit operates almost without interruption. The purpose of this mode is to remove heat from the internal volume of the chamber as quickly as possible.
When this option is activated, the refrigerator electronics ignore standard pauses in the operation of the compressor. Temperature sensor continues to read readings, but the engine shutdown threshold shifts towards lower values, often to +2...+3°C in the refrigerator compartment. This allows you to create a powerful flow of cold air, which instantly freezes the surface of the products, preventing the growth of bacteria in the first critical hours after loading.
⚠️ Attention: In intensive cooling mode, the walls of the refrigerator may become covered with frost or condensation, even in models with No Frost, if you use the function for too long. Do not leave the mode on for more than 24 hours unless necessary.
It is important to understand that Cool Plus is not a separate physical mechanism, but a software setting of the controller. It changes the operating logic of existing systems: fans, dampers and compressors. Therefore, the effectiveness of the mode directly depends on the serviceability of the main components of your refrigerator.
When it is necessary to activate the Cool Plus function
The use of emergency cooling mode is justified only in specific situations when the standard cycle is not enough to preserve the quality of products. The main scenario is loading a large volume of room temperature products. If you brought heavy bags from the store and immediately filled the shelves with them, the normal mode will take too long to restore the temperature balance.
The second important case is preparing for a long absence. If you are going on vacation and want to be sure that the food will not spoil in the first hours after your departure (for example, in the event of a short-term blackout or power surge, after which the refrigerator will resume operation), you can activate intensive cooling in advance.
The mode is also useful if you notice that the refrigerator takes a long time to restore the temperature after frequent opening of the door, for example, during a family feast. Short-term activation of the function will help quickly return the microclimate to normal.
- 🛒 You brought home a large amount of food that has already begun to heat up on the road.
- 🎉 A party is planned, and the refrigerator will often open, loading with new drinks and snacks.
- 🌡️ In the room where the refrigerator is located, The ambient temperature has sharply increased (heat in summer), and standard cooling is not enough.
- 🧊 It is necessary to quickly cool drinks or food before serving.
⚠️ Attention: Equipment manufacturers can change interfaces and names of functions in new models. Always check the user manual (manual) supplied with your specific device, as the logic of operation may differ.
Differences between Cool Plus and Super Freeze
Often users confuse the mode Cool Plus with function Super Freeze (Super Freeze), however, there is a fundamental difference between them related to the area of influence. Cool Plus is intended exclusively for the refrigerator compartment, where the temperature is usually kept at +4°C. Its task is to increase the circulation of cold air in the upper or main chamber.
The function Super Freeze, on the contrary, activates the maximum power of the freezer. It is designed for quick freezing of raw meat, fish, berries or semi-finished products so that ice crystals inside the cells of the product are minimal and do not destroy the tissue structure. These concepts cannot be mixed, as they affect different evaporators and zones inside the unit.
In some advanced refrigerator models, these functions can be combined into one algorithm or activated simultaneously by pressing one button, but in the classical sense these are two different processes. Cool Plus preserves the freshness of prepared food and vegetables, and Super Freeze preserves raw food in the freezer.
Understanding this difference allows you to avoid wasting energy. There is no point in turning on freezing if you just need to cool a bottle of lemonade, and vice versa - the cooling mode is not enough to effectively freeze fresh meat without losing its properties.
The influence of the mode on energy consumption and equipment life
Activation of the function Cool Plus inevitably leads to an increase in electricity consumption. Since the compressor operates non-stop or with minimal pauses, its energy consumption can increase by 1.5–2 times compared to the standard cycle. For modern inverter compressors, this is less critical than for older linear models, but the meter will still spin faster.
As for the service life of the equipment, short-term operation in enhanced mode does not harm a working refrigerator. Modern engines are designed for such loads. However, constant being in the mode Cool Plus can lead to premature wear of the moving parts of the compressor and overheating of the windings.
In addition, prolonged operation at the power limit increases the load on the heat removal system (condenser), usually located on the back wall. If the refrigerator is located close to the wall or in a niche without ventilation, the risk of overheating and failure of the unit increases significantly.
| Parameter | Standard mode | Cool Plus mode |
|---|---|---|
| Compressor operation | Cyclic (on/off) | Continuous or with rare pauses |
| Temperature in the chamber | Stable (+4...+6°C) | Reduced (+2...+3°C) |
| Energy consumption | Normal | Increased |
| Noise level | Normal | Maximum |
Thus, the economic feasibility of using the mode is obvious: we turn it on only when it is really needed to save products, and turn it off immediately after achieving the result.
Instructions: how to turn the mode on and off
Control of the Cool Plus function depends on the model of your refrigerator and the type of control panel. In most cases, there is a separate button on the front panel with a corresponding inscription or icon (often depicted as a snowflake with arrows or inscription Power Cool). A short press is enough to activate.
On touchscreen models, you may need to unlock the control panel. Typically this requires holding down the lock button for 3 seconds. After unlocking (Unlock), you can safely press the mode selection button. The indicator on the display will light up, confirming the activation of the function.
☑️ Algorithm for activating the mode
To turn off the mode, the actions are similar: pressing the same button again should deactivate the function and the indicator will go off. In some models, the refrigerator automatically exits the mode Cool Plus after a certain time (usually 24 hours) or after reaching the target temperature, but relying on automation is not always worth it - it is better to control the process manually.
If the button does not respond, check whether the Demo Mode is enabled, in which the refrigerator simulates operation, but does not cool. Exiting demo mode is usually described in the instructions and requires a combination of buttons.
What to do if the button does not work?
If the control panel is locked and unlocking does not help, there may be an electronics failure. Try unplugging the refrigerator for 10-15 minutes to reboot the controller. If the problem persists, a call to the wizard is required.
Typical problems and ways to solve them
Users may encounter a situation where the mode Cool Plus turned on itself or, conversely, does not want to activate. Unauthorized switching on often indicates a malfunction of the temperature sensor or a stuck button on the control panel. If the buttons are mechanical, moisture or sticky liquid may have gotten under them.
If the refrigerator hums more than usual even after turning off the mode, the air duct damper may have frozen or the evaporator has frozen. In this case, completely defrosting the unit during the day with the power turned off helps.
It is also worth mentioning the problem of “undercooling” in this mode. If you turn on Cool Plusbut the temperature does not drop and the food spoils, this is a sign of a more serious problem: a freon leak, a compressor malfunction, or a problem with the thermostat. In such cases, the software functions will no longer help.
- 🔊 Strong noise: Check whether the refrigerator is level and does not touch the walls of the cabinet or furniture.
- ❄️ Increasing ice: Check the tightness of the door closure and the condition of the seal.
- 🔥 Heating of the side walls: In intensive operation mode, this is normal, as the condenser is working.
Frequently asked questions (FAQ)
Is it possible to keep the Cool Plus mode on all the time?
It is strictly not recommended. Constant operation at maximum power will lead to excessive energy consumption, freezing of food in the refrigerator compartment (they may freeze) and accelerated wear of the compressor. Use the mode only for a short time.
Why do vegetables freeze in the Cool Plus mode?
Because the temperature in the chamber drops to +2°C and below. Watery vegetables (cucumbers, tomatoes, herbs) at this temperature lose their structure and freeze. Put them in the freshness zone or turn off the mode after the bulk of the food has cooled.
How long does the Cool Plus mode work automatically?
In most modern models (Samsung, LG, Bosch), the automatic shutdown timer is set to 24 hours. However, the exact time depends on the specific model and manufacturer settings. It is better not to wait for automatic shutdown, but to turn off the function manually when the food has cooled down.
Does this mode affect the taste of the food?
With short-term use - no. But if you overextend the setting, food may dry out (chair) due to intense air circulation, and some types of cheeses and sausages may lose their taste due to too low a temperature.
