✅ Cross Reference Information

Common Symptoms

• Wi‑Fi indicator does not illuminate when Wi‑Fi is enabled
• LG ThinQ cannot register or discover the appliance
• Remote monitoring, notifications, or app control are unavailable
• Wi‑Fi connection drops intermittently after previously working

Check Before Replacing

• Confirm that the appliance’s Wi‑Fi or Wireless indicator responds when Wi‑Fi is enabled.
• Verify that the home router provides a 2.4 GHz network; LG appliance Wi‑Fi guidance identifies 2.4 GHz as the supported band for ThinQ setup.
• Confirm the smartphone is connected to the intended network, the password is correct, and mobile data is temporarily disabled during setup.
• Try the appliance closer to the router or eliminate obvious obstructions before attributing the problem to the module.
• Power the appliance off, disconnect electrical power, wait approximately one minute, reconnect power, and retry Wi‑Fi setup.
• With power disconnected, visually check that the Wi‑Fi module connector and harness are fully seated and undamaged; do not probe or short the board.
