What to do if my LG Air Conditioner does not generate cool air?
- K
  Kimberly GarciaAug 23, 2025
  If your LG Air Conditioner isn't cooling properly, there might be several reasons: * Ensure that curtains, blinds, or furniture aren't blocking the unit. * Clean the air filter, as a dirty filter restricts airflow. Clean the air filter once every 2 weeks. * Make sure cold air isn't escaping through ventilation points. * Set the desired temperature lower than the current room temperature. * Avoid using heat sources nearby, like ovens. * Ensure the unit is in cooling mode, not air circulation mode. If the outside temperature is very high, the unit's cooling capacity may be insufficient.

Why does my LG LS120HEV emit mist from the indoor unit?

  Dale GarciaAug 31, 2025
  Mist coming from the air outlet of your LG Air Conditioner's indoor unit is normal. It's caused by cooled air forming a mist. If you lower the room temperature, the mist should stop forming.

  If you cannot adjust the temperature on your LG Air Conditioner, it may be because air circulation or jet cool/jet heat mode is selected. Change the indoor unit mode to adjust the temperature.

  If you're unable to adjust the fan speed on your LG Air Conditioner, it might be because the unit is in auto operation, jet cool/heat, or dehumidifying mode. Try changing the indoor unit mode to adjust the fan speed.

Why my LG Air Conditioner does not generate warm air?
- U
  ulambertAug 28, 2025
  There are a couple of reasons why your LG Air Conditioner might not be generating warm air: * When heating mode is first started, the unit prepares warm air, which is normal. * If the outdoor unit is in defrost mode due to ice/frost buildup on the coils (especially when the outside temperature is low), wait approximately 15 minutes for the defrost operation to complete.

  rachel89Aug 26, 2025
  If your LG Air Conditioner suddenly stops, consider these possibilities: * Check if the timer function is set to turn off the unit at a specific time and adjust the timer settings as needed. * If a power failure occurred, the system might be rebooting with the auto restart default setting. If power failures are frequent, ensure auto restart is enabled for quick power up.
