What to do if my LG Air Conditioner does not generate cool air?
- M
  Mr. Jose MayAug 16, 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.

  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.

Why my LG LS090HEV does not generate warm air?
- S
  Sarah HarveyAug 31, 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.
