Purchase a new refrigerator LG is always a joyful event, marking the update of kitchen appliances and the emergence of modern functions like Smart Cooling or Total No Frost. However, joy can give way to anxiety if the initial installation is not performed correctly, which in the future threatens to break down an expensive inverter compressor or violate the temperature regime.
Many users mistakenly believe that it is enough to simply plug the cord into an outlet, but for Korean equipment there are strict preparation regulations. Transport bolts, settling time and initial calibration of sensors play a critical role in durability unit.
In this article we will analyze each stage in detail: from unpacking to connecting to the application LG ThinQ. You will learn why you cannot ignore the floor level and how to correctly set up freshness zones in the first hours of operation.
Proper preparation of the installation site is the foundation for stable operation. If you plan to integrate the equipment into a set or simply place it in a niche, make sure that the minimum clearances for ventilation are maintained, otherwise the system No Frost will begin to work with overload.
Place preparation and unpacking of equipment
Before bringing the box into the kitchen, you need to measure the free space. Refrigerators LG often have increased depth due to the air circulation system at the back, so the distance to the rear wall should be at least 5-7 centimeters.
It is important to check the horizontality of the floor at the installation site. Even a slight tilt can lead to the doors not fitting tightly and, as a result, to ice freezing or a constant hum of the engine. Use a building level to check.
When unpacking, proceed carefully so as not to damage the enamel coating or glass shelves. Remove the top cardboard cover, remove the foam pads and carefully remove all internal elements: egg trays, vegetable containers and shelves.
- 📦 Check the contents: instructions, warranty card and all removable shelves.
- 🧹 Make sure there are no foreign objects, protective film or packaging inside the camera tape.
- 🧼 Wipe the internal surfaces with a damp cloth and a mild detergent to remove factory dust.
Pay special attention to the condition of the rubber seals on the doors. They must be clean and elastic. If you notice creases or dirt, they must be eliminated before use, since this is a seal.
Removing the transport bolts and stabilization
This is the most critical stage, which is often ignored, which leads to dire consequences. At the bottom of the rear wall of the refrigerator LG there are shipping boltsthat secure the compressor and shock absorbers during transportation.
⚠️ Attention: If you do not unscrew the shipping bolts before turning on, the compressor will work in rigid coupling with the body. This will cause severe vibration, rattling noise when starting and can lead to broken pipes or failure of the motor in a matter of minutes.
For dismantling you will need a wrench, which is usually included in the kit, or an open-end wrench of the appropriate size. There may be two or four bolts, depending on the model and volume of the refrigerator compartment.
After removing the bolts, be sure to save the plastic plugs that come with the kit and close the resulting holes with them. This is necessary to maintain the thermal insulation and aesthetics of the rear panel.
Now you need to level the refrigerator. Rotate the front adjustable feet until the cabinet is stable and the doors begin to slam shut slightly when opened to 45 degrees. This is ensured by a slight tilt of the case back.
Some models with the system DoorCooling+ require particularly careful balancing, since additional fans are sensitive to distortions. If the floor is uneven, use pads for the feet, but avoid soft materials such as carpet.
Initial start-up and waiting time
After the refrigerator is installed in place and freed from the latches, the main question arises: when can it be turned on? Here the physics of the operation of refrigerant and compressor oil comes into force.
If transportation was carried out in a vertical position, it is enough to wait 2-3 hours. This time is necessary for the oil to drain into the compressor crankcase and equalize the pressure in the system. If the refrigerator was lying on its side, the waiting time increases to 12-24 hours.
Do not rush to load food immediately after turning it on. An empty refrigerator must run one full cooling cycle so that the sensors Smart Sensor are calibrated and the refrigerant is evenly distributed throughout the evaporators.
Plug in the device. The indicators on the control panel will light up and you will hear the engine start for the first time. Modern inverter compressors LG work very quietly, so listen carefully.
For the first few hours the unit will work almost non-stop, reaching the set temperature. This is normal operation. Do not open the doors frequently during this period so as not to disturb the cooling process.
Setting temperature modes and functions
After entering the mode, you need to configure the optimal parameters. By default, refrigerators LG usually have factory settings: +3°C for the refrigerator compartment and -18°C or -20°C for the freezer.
For everyday food storage, it is recommended to set the temperature in the main chamber in the range from +2°C to +4°C. This is the most favorable environment for suppressing bacteria and maintaining freshness.
If your model has a zone Fresh Zone or Zero Degree, it can be used for storing meat, fish or defrosting food. The temperature there usually stays around 0°C, which prevents freezing but prolongs shelf life.
| Storage area | Recommended temperature | What to store |
|---|---|---|
| Top shelves | +3...+5°C | Ready food, drinks, confectionery |
| Lower shelves | +2...+3°C | Raw meat, fish, dairy products |
| Door shelves | +5...+7°C | Sauces, drinks, food products preservatives |
| Vegetable drawer | +5...+8°C | Fruits, vegetables, herbs (high humidity) |
Remember to activate the quick cooling functions if you have just loaded a lot of warm foods. The Express Freeze mode in the freezer will help quickly freeze supplies without affecting the temperature in the main compartment.
Connecting to Wi-Fi and setting LG ThinQ
Modern refrigerators LG are part of the smart home ecosystem. Connecting to a Wi-Fi network allows you to remotely control the temperature, receive notifications about an open door, and even diagnose faults.
To get started, download the app LG ThinQ on your smartphone (available for iOS and Android). Register in the system or log into an existing account. Make sure your phone is connected to a 2.4 GHz Wi-Fi network (many smart devices do not support 5 GHz).
On the refrigerator control panel, find the Wi-Fi settings button. Typically, you need to press and hold the corresponding button for 3 seconds until the indicator starts flashing. In some models, the sequence looks like Settings → Wi-Fi → On.
- 📱 Open the application and click “+” to add a device.
- 🔍 Select the “Refrigerator” category and follow the instructions on the screen.
- 🔗 Enter the password for your Wi-Fi network when the application asks for it.
- ✅ Wait for confirmation of a successful connection (the indicator on the refrigerator will stop flashing).
The function Smart Diagnosis is especially useful: if problems arise, the refrigerator itself can analyze the system status and transmit the data to the service center or show an error code on the smartphone screen.
⚠️ Attention: The application interface LG ThinQ and the location of the buttons may change with software updates. If you do not find the option you need, check the current instructions in the “Support” section on the manufacturer’s official website.
What to do if the refrigerator does not see the network?
Make sure that the router does not use a hidden SSID. Try moving your phone closer to the refrigerator. Check if the antivirus on your phone is blocking the connection of new devices. In rare cases, it is necessary to reset the network settings of the refrigerator by holding the Wi-Fi button for a long time.
Typical errors when turning on for the first time
Even following the instructions, users often make mistakes that can shorten the life of the equipment. One of the most common is to install the refrigerator close to the wall or in a niche without gaps.
The system No Frost requires constant air circulation around the condenser. If the heat is not removed, the compressor will work continuously, trying to compensate for overheating, which will lead to premature wear.
Another mistake is loading a large amount of room temperature food into an empty refrigerator that has just been turned on. This creates a colossal load on the system.
Ignoring the floor level leads to the fact that the doors do not close themselves. In models with Door-in-Door this is especially critical, since the seal of the outer compartment is broken, and the food in the door may spoil.
☑️ Check before operation
Also, do not use aggressive chemicals to wash the interior plastic surfaces. This may lead to cracks or discoloration of the plastic, especially in the backlight areas.
Frequently asked questions (FAQ)
How long does it take for an LG refrigerator to reach temperature for the first time?
Usually, an empty refrigerator requires 4 to 6 hours of continuous operation to reach the set temperature parameters work. It may take up to 12 hours for temperatures to fully stabilize in all areas, including door shelves. Do not load food until the end of this period.
Why does the LG refrigerator make a loud buzzing or clicking noise when first starting up?
Clicking noises are the normal operation of thermostats and the expansion/constriction of plastic parts when the temperature changes. The humming noise may be due to the operation of the compressor or fans. If the sound does not resemble metal knocking on metal and stops after a while, this is normal. Check that the shipping bolts have been removed.
Do you need to defrost an LG refrigerator with No Frost?
The system Total No Frost or Smart No Frost automatically removes moisture, so forced defrosting to remove ice is not required. However, once every 6-12 months it is recommended to carry out preventive defrosting and washing for hygiene and cleaning the drainage system from dust and debris.
What does the flashing indicator on the control panel mean?
A flashing indicator most often signals that the temperature in the chamber is above normal. This can happen when you turn it on for the first time, after loading warm food, or when the door is not tightly closed. If the indicator flashes for a long time after stabilization, check the tightness of the door.
Is it possible to place an LG refrigerator on a carpet or heated floor?
You can place it on a carpet, but only if the pile is not too long and the legs do not sink, disrupting the ventilation of the bottom. Installation on a heated floor is categorically not recommended, as this disrupts heat transfer and forces the compressor to work with overload, trying to cool the chamber from below which heat enters.
