Starting new refrigeration equipment or restarting after long-term transportation is a process requiring strict adherence to the sequence of actions. Many equipment owners LG make the mistake of connecting the unit to the power supply immediately after unpacking, which can lead to compressor failure. It is important to understand that the refrigerant and oil need time to take their places in the system after shaking during transportation.
In this article we will look in detail at how the refrigerator turns on LG, what modes exist and how to set the optimal temperature for storing food. We will consider the features of models with the system No Frost and classic units, paying attention to the nuances of the first operation.
The correct start of the device guarantees its durability and energy efficiency. Ignoring simple rules may void the manufacturer's warranty, so carefully study the recommendations before pressing the power button.
⚠️ Attention: If the refrigerator was transported lying down, the settling time before turning on should be at least 4-6 hours, and it is better to leave it for a day in an upright position.
Preparation for the first start and settling time
Before connecting the device to the network, you must make sure that it is installed on a flat, horizontal surface. The legs of the refrigerator LG equipped with adjustable supports, which allows you to compensate for uneven floors. If the unit is placed at an angle, the doors may not close tightly, which will lead to the formation of ice and increased load on the motor.
The key point is the time delay after delivery. When transported over long distances, oil from the compressor could leak into the system circuits. If you start the engine immediately, it will run dry, which critically reduces the service life compressor. For models with an inverter motor, this parameter is also important, despite their increased reliability.
After installation, remove all shipping tapes, films and fixing elements inside the chambers. Pay special attention to shelves and drawers - they must be installed according to the instructions. Only after completely removing the packaging can you proceed with the electrical connection.
Connecting to the electrical network and checking the voltage
Refrigerators LG are sensitive to voltage drops in the network. Before plugging into a power outlet, make sure that the wiring in your home is in good working order and that there is a ground connection. The use of extension cords or tees is not recommended, as they can cause poor contact and heating of the connections.
Some models provide protection against power surges, but you should not rely only on built-in systems. If there are frequent power outages in your area, it is advisable to purchase a stabilizer. This is especially true for expensive models with electronic control and a display.
After connecting the device to the outlet, you will hear a characteristic click - this is the start relay. After a few seconds the compressor should start working. In the first minutes of operation, the equipment may make louder sounds than usual, as the system enters an operating rhythm.
⚠️ Attention: Do not plug in the refrigerator if the power cord or plug is visibly damaged. This may result in a short circuit or electric shock.
Activating the control panel and selecting a mode
After power is applied, the control panel may not respond immediately. In some models LG it is necessary to activate the display by pressing the Power or Freeze button (depending on the series). On touch screens, it is sometimes necessary to briefly hold the power button for 3 seconds.
Modern refrigerators often start in standard mode, which is preset by the factory. However, for quick freezing or, conversely, for energy saving, the settings can be changed. The interface can be represented by either physical buttons or a touch panel Touch Display.
If the indicators light up on the display, but the temperature is not displayed, wait 5-10 minutes. The system performs self-diagnosis and calibration of sensors. At this time, do not open the doors so as not to disturb the primary cooling process.
☑️ Primary activation
Setting the temperature mode
The optimal temperature in the main chamber should be from +3°C to +5°C, and in the freezer - -18°C and below. To set these parameters, use the arrow buttons or touch zones Temp. On the display LG this is usually displayed in numbers or scale divisions.
You should not immediately set the minimum possible values. A sudden change in parameters will force the compressor to work at maximum load, which is ineffective during initial startup. It is better to let the unit gain temperature gradually during the first day.
In models with a function Smart Diagnosis or a Wi-Fi connection, settings can be made through an application on a smartphone. This allows you to control the temperature conditions remotely and receive notifications about open doors.
| Mode | Temperature (Main chamber) | Temperature (Freezer) | Purpose |
|---|---|---|---|
| Eco | +5°C ... +7°C | -15°C | Energy saving with a small amount of food |
| Standard | +3°C ... +5°C | -18°C | Daily food storage |
| Super freezing | Not changes | -24°C | Quick freezing of fresh food |
| Vacation | +15°C | Working | Keeping the freezer operating when the main chamber is closed |
Features of the No Frost system
Technology No Frost means that an ice crust will not form in the chambers. Immediately after turning on, you may hear a fan noise - this is normal. The circulation of cold air begins almost instantly after the compressor starts.
Unlike drip systems, there is no need to wait for water to appear in the groove. Cooling occurs uniformly throughout the entire volume. It is important not to clutter the back wall of the chambers with food, so as not to block the channels air circulation.
The first defrosting cycle in such refrigerators occurs automatically at certain intervals. If you hear cracking or clicking of plastic in the first hours of operation, do not be alarmed - this material adapts to temperature changes.
⚠️ Attention: In No Frost refrigerators, you cannot store food without packaging, as a powerful air flow will quickly dry out their surface.
Indication of operation and possible errors when start
If after switching on the display LG the error icon lights up or the temperature indicator flashes, this is a signal of a malfunction or violation of operating conditions. Error codes such as rF (defrost error) or dH (defrost problem) may appear if the sensors are not reading the data correctly.
Often, flashing temperatures indicate that the set cold level inside the chambers has not yet been reached. This is normal for the first run, which can last up to 24 hours. If the indicator continues to blink after a day, it is worth checking the tightness of the doors.
To reset the error, sometimes it is enough to unplug the refrigerator for 10–15 minutes and turn it on again. If the problem recurs, you must contact a service center, since repairing the electronics yourself can lead to permanent failure.
What do the flashing indicators mean?
If only the temperature number is flashing, it means the cooling process is in progress. If the lock or key icon is flashing, the child lock is activated. To unlock, you usually need to hold down the corresponding button for 3-5 seconds.
Time to enter operating mode
Complete cooling of the internal volume to the specified parameters takes time. For an empty refrigerator LG this process takes about 4-6 hours. If the chambers are loaded with products, the time may increase to 12 hours or more.
It is not recommended to load a large volume of warm products immediately after switching on. This will create an excessive load on the system and increase the time it takes to reach the mode. It is better to fill the refrigerator gradually, in small portions.
A stable mode is considered when the compressor turns on and off at regular intervals, and the temperature inside the chambers does not fluctuate by more than 1-2 degrees. Only after reaching this state can the equipment be considered completely ready for normal operation.
Is it possible to turn on the LG refrigerator immediately after transportation?
No, it is not possible. After transportation, especially if the refrigerator has been lying down, it is necessary to let it stand in an upright position for at least 4 hours, and preferably 24 hours. This is necessary for the oil to drain into the compressor.
Why does the LG refrigerator hum after turning it on?
The hum can be caused by the operation of the compressor, the circulation of the refrigerant, or the operation of the No Frost system fans. If the sound is not accompanied by vibration of the case and is not shrill, this is normal.
How long does the quick freeze indicator light up?
In most LG models, the quick freeze mode (Super Freeze) works automatically for 18–50 hours (depending on the model), after which it turns off itself or goes into standard mode.
Do I need to wash the refrigerator before turning it on for the first time?
Yes, definitely. Factory dust or plastic smell may remain inside. Wipe the chambers with a soft cloth soaked in a weak solution of soda or a special product for household appliances, and let dry.
What to do if the refrigerator does not cool after turning on?
Wait 24 hours. If the temperature has not dropped during this time, check the tightness of the doors and the presence of gaps in the seals. If the problem is not solved, call a specialist.
