Modern refrigerators LG are equipped with complex electronic control systems that display many symbols and icons. For the average user accustomed to mechanical controls, the appearance of unfamiliar icons can be a cause for concern. Especially often questions are raised by the icon in the form of an umbrella, which lights up on the control panel at certain moments.
In fact, this symbol does not indicate a breakdown or malfunction of the unit. Umbrella is a function indicator Smart Saving Mode (energy saving mode), which is automatically activated at night or when the door is rarely opened. Understanding the logic of this system will help you effectively manage energy consumption without losing the quality of food storage.
In this article we will examine in detail the purpose of the energy saving mode, the algorithm of its operation and methods for manually controlling the indication. You will find out why the manufacturer chose this graphic designation and how to distinguish the normal operation of the electronics from real sensor malfunctions.
Purpose of the Smart Saving Mode
The function Smart Saving Mode was developed by engineers LG Electronics to optimize the operation of the compressor during periods of low load. When you sleep or are away from home, the frequency of opening the refrigerator door is reduced to a minimum. At such moments, there is no need to maintain maximum cooling intensity, since heat inflows from outside are minimal.
Umbrella icon lights up on the display, indicating that the refrigerator has switched to an economical operating mode. In this state, the compressor speed decreases and the intervals between starts increase. This allows you to significantly reduce energy consumption without disturbing the temperature inside the chambers, since the sealed circuit effectively retains the cold.
The system automatically analyzes user behavior. If the door has not been opened for a long time (usually about an hour), the electronics itself decides to switch to economy mode. A visual display of this process in the form of an umbrella helps the user to understand that the unit is operating in a normal but optimized mode.
⚠️ Attention: The energy saving mode is not intended for long-term storage of large quantities of fresh products just loaded into the chamber. If you bought a lot of products, wait until they are completely cooled before activating the economy mode.
It is important to note that the presence of this mode is typical for models with inverter compressor and a digital display. In older or budget models without a screen, this function may be absent or not have a visual display.
Operation logic and automatic activation
The algorithm for enabling the function Smart Saving is based on the analysis of time intervals between openings refrigerator doors. The electronic control unit (ECU) records every interaction with the device. If the time interval between openings exceeds the factory limit, the system considers that user activity is low.
At this moment, umbrella indicatorlights up on the display. This means the temperature in the refrigerator compartment can be raised 1-2 degrees above your set point, which is still safe for most foods but beneficial for your electricity bill. The compressor works less intensively, creating less noise.
As soon as you open the door, the sensor sends a signal to the controller. LG programmed the system so that it instantly responds to the onset of activity. The umbrella disappears from the screen and the refrigerator goes into standard cooling mode, restoring the set temperature parameters.
It is worth considering that the transition to economy mode does not occur instantly after the last closing of the door. There Activation delaywhich prevents frequent switching of modes during short pauses in using the device. Typically, this interval is from 60 to 90 minutes.
How to manually enable or disable the icon
The user can independently control the energy saving function without waiting for the timer to automatically fire. This is convenient if you know that you are going away for the weekend or, conversely, are planning a party with frequent access to products. Control is carried out through a panel of buttons on the front of the case.
To switch modes, a button labeled Eco, Energy Saver or a key combination depending on the specific refrigerator model is usually used. LG. When you press this button, you forcefully activate or deactivate the mode. The corresponding umbrella icon will either light up or go out on the display.
On some models with touch controls (Touch Control), you must press and hold the button for 3 seconds. This protects against children accidentally changing the settings. If, after pressing, the icon does not respond, it may be activated locking the control panel (Child Lock), which must be removed before changing the parameters.
☑️ Checking mode control
When you manually turn on the mode, you take responsibility for the temperature regime. If you forcibly turned on energy saving (the umbrella caught fire), but then often opened the door, the temperature inside may rise above the safe one, since the system will not have time to compensate for heat inflows.
Differences from other indicators on the display
Panel refrigerator control LG contains many symbols and they are easy to confuse. It is important to be able to distinguish between operating modes and fault signals. The umbrella is the only symbol indicating the economy mode, but other indicators may also light nearby.
Users often confuse the umbrella with the snowflake symbol. Snowflake indicates the fast freezing or intensive cooling mode (Express Freeze / Express Cool). Unlike the umbrella, this mode requires maximum compressor power and increased energy consumption. It is activated manually to quickly cool new products.
Also on the display there may be an icon Wi-Fi (for models with Smart ThinQ) or a symbol Lock (lock). None of them are related to energy conservation. The umbrella always indicates a decrease in cooling activity in order to save money.
| Symbol | Mode name | Impact on operation | Energy consumption |
|---|---|---|---|
| ☂️ (Umbrella) | Smart Saving | Power reduction | Minimum |
| ❄️ (Snowflake) | Express Freeze | Maximum power | High |
| 🔒 (Lock) | Child Lock | Button lock | No changes |
| 📶 (Wi-Fi) | Smart Connection | Data transfer | Minor |
Understanding the differences between these symbols allows correctly interpret the state of the device. If you see it burning umbrella, it means the refrigerator is “resting”. If it lights up snowflake it works in enhanced mode.
The influence of the mode on the safety of products
Many users fear that the energy saving mode can negatively affect the freshness of products. However, engineers LG provided for safe limits. Increase in temperature in the refrigerator compartment when activated Smart Saving Mode insignificant and usually does not exceed +5...+7°C, which is within acceptable limits for most products.
However, there are categories of goods that require strict adherence to temperature conditions. These include open dairy products, fresh meat, fish and some types of vegetables. If such products are stored in your refrigerator, it is better to keep the energy saving mode turned off or minimize its operating time.
What products are sensitive to temperature?
The most sensitive to temperature increases: open yogurts, soft cheeses, chilled meat and fish, ready-made salads with mayonnaise. For them, stable cooling below +4°C is critical.
In the freezer, the mode Smart Saving can also slightly increase the temperature, but due to the large reserves of cold in frozen products, this rarely leads to their defrosting. However, for long-term storage (> 1 month), standard operating mode is still recommended.
⚠️ Attention: If you notice that food in the refrigerator compartment has begun to deteriorate faster than usual or an unpleasant odor has appeared, immediately turn off the energy saving mode. Perhaps your refrigerator requires maintenance or refilling with refrigerant.
Use umbrella mode is justified at night or during holiday periodswhen access to the refrigerator is limited and there are products inside with a long shelf life (canned food, drinks, peeled vegetables).
Possible malfunctions and diagnostics
Although a burning umbrella most often means normal operation, there are situations when this indicator behaves strangely. For example, it blinks, does not light up when left idle for a long time, or, conversely, does not go out after opening the door. This may indicate problems with the sensors or control board.
If the icon flashes along with other indicators or a sound signal, this is an error code. In models LG blinking combinations indicate specific components: evaporator temperature sensor, fan malfunction or problems with the inverter. In such cases, you need to contact the instructions or service center.
Sometimes the problem lies in a stuck control panel button. If the button Eco is physically stuck pressed, the refrigerator will think that you are constantly asking for energy saving to be turned on. Check the cleanliness and movement of the buttons on the panel.
In case of persistent (permanent) errors, when the mode is not switched manually and the automation does not work, a malfunction is likely electronic module. Independent repair of complex electronic circuits is not recommended, as it requires special equipment and knowledge.
Tips for effective use
To ensure that your refrigerator LG serves for a long time and saves money, use the function Smart Saving wisely. You should not keep this mode on all the time if you have a large family and actively use the refrigerator during the day. It is optimal to allow the system to operate automatically.
Make sure the door is closed tightly. If the seal is worn out and the door does not fit tightly, the opening sensor may not work correctly and the energy saving mode will not turn on, although heat will actually flow into the chamber. Regularly check the condition of the rubber seal.
Do not overload the refrigerator with food. For efficient operation in any mode, including economical, air circulation is necessary. If the shelves are filled to capacity, the temperature sensors may show incorrect data, and the switching logic will be broken. umbrella will be violated.
Frequently asked questions (FAQ)
Why does the umbrella icon light up during the day when I'm at home?
This can happen if you haven't opened the refrigerator for a long time (for example, everyone went for a walk or was sleeping). Also check if the button Eco was pressed accidentally or if it is stuck. If the problem occurs frequently, the door sensor may be faulty.
Is it possible to completely disable the Smart Saving function?
In most models LG you can manually turn off the mode by pressing the corresponding button. However, this function cannot be completely removed from the refrigerator’s firmware, since it is part of the basic logic of the manufacturer’s energy-saving algorithms.
Is frequent switching of modes (umbrella back and forth) harmful for the compressor?
No, modern inverter compressors LG are designed for a smooth change in power and frequent on/off cycles or speed changes. The protection system prevents wear and tear from frequent mode switching.
What to do if the icon is on, but the refrigerator is not cooling?
If the energy saving indicator is on, but it is warm inside, this is a sign of a malfunction. The compressor may have failed, a freon leak has occurred, or the temperature sensor has broken down. In this case, the icon may light up falsely. A call from a specialist is required.
