  To connect your LG Refrigerator to Wi-Fi, ensure the Wi-Fi password is correct. If incorrect, remove the Wi-Fi network from your smartphone and re-register the appliance on LG SmartThinQ. Turn off mobile data on your smartphone and use the Wi-Fi network for registration. The wireless network name (SSID) should use only English letters and numbers, without special characters. Only a 2.4 GHz router frequency is supported, so set your wireless router accordingly. If the distance between the appliance and the router is too far, move the router closer to the appliance.

  If you find frost forming in the freezer compartment of your LG Refrigerator, make sure that food items are not blocking the door and that the door is tightly closed. Also, cool hot food before storing it in the freezer. Ensure that the air entry and exit are not blocked to allow proper air circulation, and avoid overfilling the freezer to maintain appropriate space between items.

  If your LG Refrigerator is noisy and generating abnormal sounds, make sure it's installed on a solid, flat surface. Adjust its position to allow enough clearance around it and ensure the rear of the appliance isn't touching the wall. Remove any objects scattered behind or on top of the appliance.

  If you see condensation inside your LG Refrigerator or on the bottom of the vegetable drawer cover, make sure you cool hot food before storing it. If you left the door open, close it and wipe away any condensation with a dry cloth. Avoid opening and closing the door too frequently, and store warm or moist food in sealed containers.

  If you notice frost or condensation forming inside or outside your LG Refrigerator, it might be due to frequent door openings or an improperly closed door, which allows outside air to penetrate. Also, condensation can appear on the exterior if the installation environment is humid; wipe off any moisture with a dry cloth.
