Why is my LG Air Conditioner not emitting cool air?
- C
  Calvin HopkinsAug 15, 2025
  Your LG Air Conditioner might not be emitting cool air because the air filter is dirty; clean it every two weeks. Also, ensure that curtains, blinds, or furniture aren't blocking the unit. The room temperature might be too high, so select Jet Mode for faster cooling. Check for escaping cold air and ensure the set temperature is lower than the current room temperature. Avoid using heat generators nearby, and make sure the unit isn't in Fan Mode.

  If your LG Air Conditioner isn't working, first check if it's plugged in and the power isolators are on. Replace the fuse or check the circuit breaker if it has tripped. If there was a power failure, wait 3 minutes after power is restored before turning the unit back on. Also, ensure the batteries in the remote controller are correctly inserted or replace them. Finally, check if the air conditioner was turned off automatically at a preset time and turn it on.

Why is my LG Air Conditioner not emitting warm air?
- J
  Jennifer SantosAug 26, 2025
  If your LG Air Conditioner isn't emitting warm air, and the vane is almost closed when Heating Mode starts, wait until the unit generates enough warm air to blow through the indoor unit. If the outdoor unit is in Defrosting Mode, allow approximately 15 minutes for the process to finish. Note that if the outside temperature is too low, the heating effect may not be sufficient.

  Andrew SmithAug 28, 2025
  If your LG Air Conditioner stops suddenly during operation, check the timer settings. If a power failure occurred, wait for the power to come back. If you have the Auto Restart function enabled, your unit will resume its last operation several minutes after power is restored.

  michaeljohnsonAug 31, 2025
  If your LG Air Conditioner and smartphone aren't connecting to Wi-Fi, ensure you're using the correct password. Remove the Wi-Fi network from your smartphone and re-register the appliance on LG ThinQ. Turn off mobile data on your smartphone and use Wi-Fi for registration. The wireless network name (SSID) should only contain English letters and numbers. Set the wireless router to 2.4 GHz and ensure the router is closer to the appliance.

Why is my LG VM122H9 NJM2 Air Conditioner indoor unit still operating when turned off?
- W
  Walter DawsonSep 4, 2025
  The indoor unit of your LG Air Conditioner may still operate after being turned off because the Auto Clean function is active. This feature removes remaining moisture inside the unit. Allow the function to continue, or turn the unit off to disable it.
