Prerequisites: What You’ll Need Before Setup
To ensure a smooth setup, gather the following:
1. A Stable 2.4GHz Wi-Fi Network
LG air conditioners only connect to 2.4GHz Wi-Fi bands. Most modern routers broadcast both 2.4GHz and 5GHz signals. Make sure your network name (SSID) for the 2.4GHz band is visible and not hidden.
Tip: If your router combines both bands under one name (called “band steering”), temporarily separate them or rename the 2.4GHz network (e.g., “HomeWiFi_2.4”) to avoid confusion.
2. Your Wi-Fi Password
Have your Wi-Fi password ready. It’s case-sensitive, so double-check capital letters and special characters.
3. A Smartphone or Tablet
You’ll need a device running iOS 15+ or Android 10+ to download and use the LG ThinQ app.
4. LG ThinQ App Installed
Download the latest version of the LG ThinQ app from the Apple App Store or Google Play Store. As of 2026, the app supports enhanced security, faster pairing, and improved device management.
5. Power and Proximity
Ensure your air conditioner is plugged in and powered on. Keep your phone within 10 feet of the AC during setup for a strong Bluetooth signal (used in initial pairing).
Also confirm your router’s firewall isn’t blocking local device discovery; some “guest” or “IoT” isolation settings can prevent the ThinQ app from seeing the AC.

- Enter the password carefully—mistakes here are a common cause of failure.
- Tap “Connect.”
The app will send the network info to your AC. This may take 30–60 seconds.
Step 6: Wait for Confirmation
If successful, the AC’s WiFi light will stop blinking and stay solid. The app will display a confirmation message: “Connected to Wi-Fi.”
You may also see your AC appear on the app’s home screen with its current status (e.g., “Off,” “Cooling,” temperature).
Step 7: Test Remote Control
Try turning the AC on and off from the app. Adjust the temperature, change modes (Cool, Fan, Dry), or set a timer.
If everything works, congratulations—your LG air conditioner is now connected to WiFi! Verify the connection works from a cellular network (turn off phone WiFi) to confirm true remote access.
