  Andrea TorresAug 16, 2025
  First, verify that the power cord of your LG Air Conditioner is securely plugged into the outlet and that the power isolators are switched on. If the unit still doesn't power on, check the fuse to see if it has exploded, and replace it if necessary. Also, check your circuit breaker to see if it has tripped. If a power failure has occurred, turn off the air conditioner and wait three minutes after the power is restored before turning it back on. Ensure that 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 blowing cold air?
- R
  Richard GoodwinAug 18, 2025
  Several factors can cause your LG Air Conditioner to not blow cold air. Ensure that curtains, blinds, or furniture aren't blocking the front of the unit, restricting airflow. Clean the air filter every two weeks. In summer, select Jet Mode for faster cooling. Seal any ventilation points to prevent cold air from escaping. Set the desired temperature lower than the current room temperature. Avoid using heat generators nearby. Ensure the unit is not in Fan Mode; switch to cooling. Lastly, if the outside temperature is excessively high, the cooling effect might be reduced.

  Your LG Air Conditioner might be turning off due to the Timer Function timing out; check the timer settings. Alternatively, a power failure during operation could be the cause. If you have the Auto Restart function enabled, the unit will resume operation several minutes after power is restored.

Why is my LG S4NQ18KL31A Air Conditioner not blowing hot air?

  If your LG Air Conditioner isn't emitting warm air, it could be in Defrosting Mode to remove frost from the coils, which takes about 15 minutes. Also, when Heating Mode starts, the vane may be closed until enough warm air is generated. If the outside temperature is too low, the heating effect may not be sufficient.

  If the indoor unit of your LG Air Conditioner continues to operate after being turned off, the Auto Clean function may be running. This feature removes moisture from inside the unit. Allow it to complete, or disable the function if you prefer.

  Odors, like cigarette smoke, can be absorbed into your LG Air Conditioner and released with airflow. If the smell persists, wash the filter. If this doesn't resolve the issue, contact the service center to clean the heat exchanger.

  The mist coming from the air outlet of your LG Air Conditioner is due to the cooled air forming mist. This will disappear as the room temperature decreases.
