Owners of modern home appliances often face the need to integrate their devices into a unified smart home ecosystem, and the first step is connecting to a wireless network. However, the connection process can be interrupted by an unexpected system request for credentials—the device's authorization information. Many users are confused, unsure where to get these credentials and why the default router passwords aren't suitable for initial pairing.
The question of what the Wi-Fi password is on an LG refrigerator is technically incorrect, as it confuses the local network password with the appliance's security PIN. In most cases, it refers to the factory code required for your smartphone or tablet to detect the freezer and transmit router settings. This code is unique to each appliance and serves as protection against unauthorized access to the appliance.
Understanding the difference between these data points is critical to successfully tuning the function. SmartThinQ, which allows you to remotely manage temperature, receive notifications, and perform diagnostics. In this article, we'll detail the physical location of the data sticker, what to do if the sticker is lost, and how to properly reset the network if previous attempts have failed.
Where can I find the factory PIN code on the device?
The first place to look for the necessary data is the physical label affixed by the manufacturer to the appliance body. It's typically located on the inside wall of the refrigerator compartment, often on the left side panel or on the door, so it's still accessible even after the unit is installed in the kitchen. This label contains all the essential technical information: serial number, model, production date, and, most importantly for us, the designation line. PIN Code or WPS PIN.
Sometimes the information may be duplicated on the back of the device, but accessing it to view the sticker is inconvenient and risky, as it requires moving the heavy device. If you see a QR code on the inside, it often contains a PIN code that can be scanned with a smartphone camera via an app. LG ThinQ, which eliminates the need to manually enter a long combination of numbers. For some models, especially those released in the last two years, the code may also be included in the quick installation instructions included in the box.
Please note that the combination you are looking for consists exclusively of numbers and usually contains 4 to 8 characters. Do not confuse this code with the serial number (Serial No), which contains letters and numbers and is required for warranty registration, but is not suitable for network setup. Entering an incorrect code will result in a pairing error, and the system will have to be restarted, resetting the Wi-Fi module.
⚠️ Attention: Never attempt to remove the factory label from the inside of the door to move it to a more convenient location. The adhesive backing can damage the interior of the unit, and the label itself contains important refrigerant information that a service technician may need during servicing.
Procedure for activating pairing mode
Simply knowing the code isn't enough; you need to set the refrigerator's communication module to discoverable mode so it can broadcast a signal to your mobile device. To do this, find the button marked as Wi-Fi, SmartThinQ or the combination of buttons specified in the instructions for your specific model LG InstaView or LG DoorCoolingIn most cases, you need to press and hold this button for 3-5 seconds until the corresponding indicator appears on the display.
Once setup mode is activated, the Wi-Fi indicator will begin flashing, indicating the device is ready to receive data. At this point, the smartphone app will prompt you to enter the PIN code we looked for earlier. If you don't manually activate this mode, the refrigerator won't appear in the list of available devices to add, even if it's within range of the router.
It's important to understand that pairing mode is active for a limited time, typically around 10-15 minutes. If setup isn't completed within this time, the module will automatically exit standby mode to save power and ensure safety. In this case, you'll need to repeat the process of enabling discoverable mode by pressing the appropriate button on the control panel again.
- 📱 Make sure that Bluetooth and geolocation are enabled on your smartphone, as modern protocols IoT use them for initial device detection.
- 📶 Connect your phone to the same Wi-Fi network (2.4 GHz) that you plan to connect your refrigerator to, as connecting directly to 5 GHz often causes errors.
- ⏱️ Do not move far from the refrigerator during setup to ensure a stable Bluetooth pairing signal.
Setup via the LG ThinQ app
The central element of the LG ecosystem is the mobile app LG ThinQ, which acts as an intermediary between your smartphone and your refrigerator. After downloading and registering an account, click the "Add Device" button and select the "Kitchen" or "Refrigerator" category. The app will prompt you to scan the QR code from the sticker on the device or enter the PIN manually, after which the automatic configuration process will begin.
During the setup process, the app will transmit your home network's SSID and password to the refrigerator. This is where many users get confused, thinking the system is asking for the refrigerator's password. In reality, you're entering your router's password to "introduce" the refrigerator to the internet, using the device's PIN you previously entered to log in to the LG system.
If setup is successful, the indicator on the control panel will stop flashing and turn solid, and the app will show "Connected." From this point on, you can remotely change the temperature, activate Vacation mode, or receive door-open notifications. The app also allows you to track energy consumption and receive maintenance recommendations.
⚠️ Attention: The LG ThinQ app requires local network access permission. If you see an error when trying to add a device, check your iOS or Android privacy settings and allow local network access for this app.

Common data entry errors and their solutions
Despite its apparent simplicity, the data entry process is often plagued by human or technical errors. The most common problem is confusion between numbers. 0 (zero) and the letter O, although LG PIN codes only use numbers. Users also often enter the router code instead of the device's factory code, which results in immediate system access denial.
Another common cause of failure is incompatibility of frequency ranges. The Wi-Fi modules in most LG refrigerator models only operate in the frequency range 2.4 GHzIf your router broadcasts a 5 GHz network with the same name (SSID) or hides the network name, the refrigerator may not be able to find the access point. In this case, you need to temporarily separate the networks in the router settings or create a 2.4 GHz guest network.
If the app displays "Device not found" or "Connection error," try rebooting your router and the refrigerator itself. Sometimes a static IP address or complex security settings (such as MAC filtering) on the router block a new device. Temporarily disable MAC filtering or add the refrigerator's address to the whitelist, which can be found in the router settings menu.
| Error type | Probable cause | Solution method |
|---|---|---|
| Incorrect PIN code | The router code or serial number has been entered | Find the sticker inside the refrigerator, enter 4-8 digits |
| Connection timeout | Weak signal or 5 GHz frequency | Move closer to the router and switch to 2.4 GHz. |
| Device not found | Pairing mode is not enabled | Press and hold the Wi-Fi button for 3-5 seconds until it blinks. |
| Network error | Hidden SSID or special characters | Open the network name, remove special characters from the Wi-Fi name |
What should I do if the sticker with the code has worn off?
If the factory label is damaged or missing, the only reliable way to restore access is to perform a full reset (Reset All) through the service menu, if available, or contact an authorized LG service center. For security reasons, it is impossible to find the PIN without the physical label.
Change your Wi-Fi password and reset your network settings
Changing the Wi-Fi password on an LG refrigerator can occur when switching providers, purchasing a new router, or changing the home network security key. There's no need to search for the old password on the device, as the procedure requires completely disconnecting and establishing a new connection with the new settings. You'll need to re-enter setup mode on the control panel.
The process begins by disconnecting the current connection. On the control panel, you need to hold down the button Wi-Fi or a combination Ice Plus + Wi-Fi (Depending on the model) for 5-7 seconds. The indicators will flash, and the device will reset the saved network settings. After this, the refrigerator will return to connection standby mode, and you can use the LG ThinQ app to transfer new data from the router.
It's important to note that the refrigerator's internal network password (if it's in AP mode, which is rarely used for direct connection) cannot be changed; it's hardcoded. However, this doesn't matter to the user, as management occurs via the LG cloud, not via a direct connection to the device. The main thing is to ensure the correct settings are transmitted from your home router.
- 🔄 After changing your router password, be sure to reset the Wi-Fi on your refrigerator, otherwise it will try to connect with the old data.
- 🔐 Use strong passwords for your Wi-Fi network, but avoid special characters that may not display correctly in your home appliance's interface.
- 📡 Make sure that AP Isolation is not enabled on your router, which prevents devices on the network from communicating.
Smart Home Security and Protection
Connecting your refrigerator to the internet opens up not only opportunities but also potential risks, so it's important to follow basic digital hygiene rules. The factory PIN code we discussed is the first line of defense, preventing third-party devices from connecting to your refrigerator. Never post photos of the sticker with this code on social media or forums, as hackers can use it to access the device's controls.
Update your refrigerator software regularly via the app LG ThinQManufacturers release security patches that fix vulnerabilities in communication protocols. Ignoring updates can leave your device vulnerable to attacks, although the risk of exploding a household appliance via Wi-Fi remains more theoretical than practical.
It's also recommended to create a separate guest Wi-Fi network for smart home devices. This will isolate your main network, which contains computers and smartphones containing sensitive information, from potentially less secure home appliances. If one of your devices is compromised, an attacker will be unable to access your personal files.
⚠️ Attention: The LG ThinQ app's control interfaces and functionality may vary depending on the operating system version and region. If you don't see the options described, please consult the latest instructions on the manufacturer's official website.
Can you use a refrigerator without Wi-Fi?
Yes, all basic cooling, freezing, and additional functions (such as quick freeze) operate autonomously without an internet connection. Wi-Fi is required only for remote control, diagnostics, and notifications.
Frequently Asked Questions (FAQ)
Where exactly is the PIN sticker located if there is no PIN sticker inside the refrigerator?
If there's no sticker on the inside wall of the appliance, check the edge of the door (on the side when it's open) or the back panel of the appliance. In rare cases, this information may be printed on the warranty card or in the product data sheet, in the technical specifications section.
What should I do if my refrigerator can't see the 2.4 GHz Wi-Fi network?
Make sure your router isn't hiding your SSID (network name). Try temporarily renaming the network, removing Cyrillic characters and special characters. Also, check if your router has a limit on the number of connected devices or MAC address filtering.
Is it possible to connect an LG refrigerator to a 5GHz network?
Most Wi-Fi modules in LG appliances only support the 2.4 GHz standard. Connecting to 5 GHz is impossible. If your router combines both networks under a single name, try separating them into different SSIDs in the router settings (for example, MyWiFi and MyWiFi_5G) and connect the refrigerator to the network without a 5G adapter.
Does Wi-Fi reset when there is a power outage?
No, the network settings are saved in the device's memory even during a complete power outage. However, if you change the router password, you will have to manually reset the refrigerator's Wi-Fi settings and set them up again.
What is the maximum distance to the router for stable operation?
For reliable operation, the refrigerator's Wi-Fi module must be located within a strong signal range. Typically, this range is 10-15 meters within a single room without thick concrete walls. If the refrigerator is located further away, a Wi-Fi repeater may be required.
