Modern household appliances such as LG Smart Refrigerator, transforms the kitchen into a digital home control center, but users often encounter difficulties during initial setup or after replacing internet equipment. The question of how to find the WiFi password for an LG refrigerator actually conceals a common misconception: the device itself doesn't store your home network password in plain text, which can be easily read from the screen. Understanding the protocol architecture ThinQ and the principles of WPA2/WPA3 encryption is the key to successfully solving the connection problem.
In most cases, when asking "how to find out the password," users mean the need to restore network access so that the refrigerator can once again transmit temperature or filter status data to a smartphone. Smart Home The devices operate in client mode (Station Mode), requesting credentials from the router rather than distributing them. Therefore, the action plan will not be aimed at hacking or extracting data from the refrigerator's memory, but rather at properly configuring the access point or using alternative pairing methods, such as Soft AP.
It's important to note that trying to find the factory WiFi password inside the refrigerator itself is pointless, as it simply isn't there—you're entering your personal network details. If we're talking about the password for direct connection mode (when the phone connects directly to the refrigerator for setup), this information is unique to each unit and is located on a special sticker. Let's look at all the nuances of working with network modules. LG Electronics and methods for restoring the connection.
⚠️ Attention: Application interface LG ThinQ The refrigerator's display and menu may vary depending on the model year and region. Some older models may not support modern encryption standards, requiring manual router configuration.
How the LG ThinQ Network Module Works
To successfully integrate a refrigerator into a home network, you need to understand that the device uses a standard protocol stack IEEE 802.11 b/g/nThe communication module built into the control board functions similarly to the network card in a laptop or smartphone. It doesn't generate your internet password, but rather stores it in non-volatile memory after successful authentication. When synchronization errors occur, the problem is most often not a forgotten password, but rather incompatible frequency bands or encryption types.
Many modern routers operate in two ranges: 2.4 GHz And 5 GHzThe network module of most LG refrigerator models, especially those released before 2023, only supports the range 2.4 GHzIf your router broadcasts a single network (Smart Connect) or hides the SSID, the refrigerator may simply "not see" the access point, creating the illusion of an incorrect password. In this case, you need to separate the networks in the router settings by giving them different names, for example, HomeWiFi And HomeWiFi_5G.
Another important aspect is the type of security. Protocols WPA3The firmware updates implemented in new routers may be incompatible with older refrigerator firmware versions. In such cases, the device will continually reject the password entry, claiming it is incorrect. While the key is technically correct, the encryption algorithm is not supported. It is recommended to temporarily switch the router to mixed security mode. WPA/WPA2-PSK to carry out the pairing procedure.
Where can I find the password for Direct Access Mode (Soft AP)?
There's a scenario where a WiFi password is actually needed, and it concerns the direct configuration mode. When the refrigerator enters configuration mode, it creates its own temporary network, which you connect to with your smartphone. Accessing this network requires a special code, which is a unique identifier for the device. This code is often confused with the password for your home router, but they serve different functions.
The code (PIN) you're looking for is usually located on a factory sticker located inside the refrigerator compartment or on the back of the appliance. Look for markings with the following inscriptions: AP Key, Pin Code or simply by entering numbers next to the QR code. In some models LG InstaView or Door-in-Door This information can be duplicated in the menu Settings → Network → Network Information, if the refrigerator screen allows you to view this data before a full reset.
If the sticker is worn off or unavailable and the screen doesn't display the code, there's a standard Wi-Fi reset method that will return the device to a state where it requests a connection again, but this won't restore the lost Direct Connection PIN if it's not written down anywhere. In this case, you may need to use the NFC Tag-on (if supported by the model), where the smartphone reads data upon physical contact with the tag on the refrigerator, bypassing manual input.

⚠️ Attention: Don't get confused AP Key (the code for connecting your phone to the refrigerator) and your home WiFi password. These are two different sets of characters used at different stages of the setup process.
Resetting network settings on an LG refrigerator
If you've changed your router or home network password, the old data in your refrigerator's memory will prevent it from connecting. In this case, you'll need to reset the network settings. This won't affect temperature settings or cooling settings; it will only clear the table of saved WiFi connections. The procedure may vary depending on whether the refrigerator has a touchscreen.
For models with a display, you need to go to the main menu and select the item Settings (gear icon). Then follow the path Network → Wi-Fi Settings → Reset Wi-Fi SettingsThe system may ask you to confirm the action. After this, the WiFi indicator will start blinking, signaling that the device is in connection standby mode. The device is now ready to receive new connections. credentials.
In models without a full touch interface (with a segment display), resetting is often performed using a button combination. This is the standard sequence for most models. LG Smart: press and hold the buttons simultaneously Freezer (Freezer) and Eco Button (or Ice Plus) for 5-7 seconds. The display may show the message AP or the network indicator will flash. It's best to check the user manual for the exact combination for your model, as it varies from series to series.
☑️ Checklist before resetting the network
Setup via the LG ThinQ app
The main tool for control and configuration is a mobile application LG ThinQThis is how the password from your router is transferred to the refrigerator's memory. The process is as follows: after resetting the refrigerator's network settings, open the app on a smartphone connected to the target WiFi network. Tap "+" to add the device.
The app will prompt you to select the device type (Refrigerator) and connection method. Select "Setup via app." At this point, the app will ask you to enter your WiFi network password. Make sure to enter the characters correctly, including capitalization (upper and lowercase letters are important). After entering the password, the app will attempt to transfer this information to the refrigerator via Bluetooth or a temporary hotspot.
It's important to have geolocation and Bluetooth enabled on your smartphone, as modern versions of Android and iOS require these permissions to scan devices. If the process freezes at the "Searching for Device" stage, try disabling your phone's mobile data (3G/4G) and leaving it on WiFi only. The system may try to go online, losing the local connection to the refrigerator.
| Setup stage | User action | Indication on the refrigerator | Possible error |
|---|---|---|---|
| Preparation | Resetting the power on the refrigerator | The WiFi icon is flashing | No button response |
| Search | Starting a scan in ThinQ | The indicator is constantly on | Device not found |
| Data entry | Entering the router password | Flashing quickly | Incorrect password |
| Conjugation | Waiting for confirmation | It's on constantly | Connection timeout |
What should I do if the app says "Device not found"?
Make sure your phone and refrigerator are in the same room. Check if your phone's antivirus or firewall is blocking local scanning. Try rebooting your router.
Compatibility issues and frequency ranges
One of the most common reasons why a user thinks they "don't know the password" or that the password doesn't work is a frequency conflict. As mentioned earlier, WiFi modules in LG devices often only work on 2.4 GHzIf your router is broadcasting a 5 GHz network with the same name (SSID), your refrigerator may try to connect to it, lose the signal due to the lower penetration of high frequencies, or simply not see the network.
The solution is to create a guest network or a separate SSID for smart home devices. Go to your router settings (usually at 192.168.0.1 or 192.168.1.1) and find the "Wireless" section. Split the single network into two: MyHome_2.4 And MyHome_5Connect your phone to the 2.4 GHz network and configure the refrigerator through it.
It's also worth paying attention to the subnet mask and DHCP. Make sure automatic IP address assignment is enabled on your router. A manually assigned static IP address can, in rare cases, conflict with the gateway address, resulting in a connection error that the app will mistakenly interpret as a password issue.
Alternative connection methods (WPS and NFC)
If manual password entry is difficult or the keyboard on the smartphone screen is inconvenient, you can use technology WPS (Wi-Fi Protected Setup). This method allows you to connect to the network without entering a password, by physically pressing a button. Your router must have a button. WPS, and on the refrigerator screen (in the network menu) there should be an option “Connect via WPS”.
The process is as follows: select WPS on the refrigerator's screen, then press the WPS button on the router within two minutes. The devices will automatically exchange encrypted keys. However, this method doesn't work with all routers (especially those rented by ISPs), and WPS is often disabled by default on routers for security reasons.
For owners of smartphones with support NFC The Near Field Communication (NFC) process is even simpler. Simply unlock your phone, launch the ThinQ app, and hold the top of your smartphone over the NFC tag on your refrigerator (usually near the control panel). The phone will read the configuration file and prompt you to transfer the WiFi settings. This is the most reliable way to avoid password errors.
⚠️ Attention: The WPS function is considered less secure because it is vulnerable to brute-force attacks. After setting up the refrigerator, it is recommended to disable WPS in the router settings unless you plan to connect other devices using this method.
Frequently Asked Questions (FAQ)
Is it possible to find out the saved WiFi password by looking at it on the refrigerator screen?
No, for security reasons, no home appliance displays saved WiFi passwords in plain text on its display. You can only see the network name (SSID) the device is connected to or reset the settings and enter a new password.
What should I do if my refrigerator keyboard doesn't have Russian letters, but the password contains Cyrillic characters?
By default, WiFi router passwords must contain only Latin characters (az, AZ) and numbers. If your password contains Russian letters, you'll need to access the router settings from your computer and change the password to a Latin one, as refrigerators don't support Cyrillic characters in network key entry fields.
The refrigerator connects, but the app says "No Internet." What's wrong?
This means there's a connection between the refrigerator and the router (the password is correct), but the router itself doesn't have access to the external network. Check your ISP's cable, your account balance, or try accessing the website on your phone over the same WiFi network. The issue could also be blocked ports on your ISP's end.
How do I connect a refrigerator if I have a router with a hidden SSID (invisible network)?
LG refrigerators, like most IoT devices, don't work well with hidden networks. To ensure a successful connection, we recommend temporarily enabling the network (Enable SSID Broadcast), configuring the refrigerator, and then, if necessary, hiding the network again. However, in this case, automatic reconnection after a router reboot may not work.
