How to fix LG S4UW24K2RZD Air Conditioner not emitting cool air?
- T
  Thomas WoodAug 16, 2025
  If your LG Air Conditioner isn't emitting cool air, ensure that curtains, blinds, or furniture aren't blocking it. Regularly clean the air filter every two weeks. In summer, use Jet Mode for faster cooling. Ensure no cold air escapes through ventilation points. Set the desired temperature lower than the current room temperature. Avoid using heat generators nearby, and switch from Fan Mode to cooling. Note that the cooling effect might be insufficient if the outside temperature is too high.

  If your LG Air Conditioner does not work, first check if the power cord is properly plugged into the outlet and that the power isolators are switched on. Replace the fuse or check the circuit breaker if it has tripped. After a power failure, wait 3 minutes before turning the unit back on. Also, ensure the batteries in the remote controller are correctly inserted or replace them. If the voltage is too high or too low, check the circuit breaker. Finally, make sure the air conditioner wasn't turned off automatically by a timer and turn it back on.

Why does my LG S4UW24K2RZD Air Conditioner keep turning off?
- M
  Michael SmithAug 22, 2025
  If your LG Air Conditioner stops during operation, the Timer Function may have timed out, turning the unit off, so 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.

Why is my LG S4UW24K2RZD Air Conditioner not blowing warm air?
- C
  Christopher MartinAug 28, 2025
  When the LG Air Conditioner is in Heating Mode, the vane is almost closed, and no air comes out, even though the outdoor unit is operating. This is normal; wait until the unit has generated enough warm air to blow through the indoor unit. Also, the outdoor unit may be in Defrosting Mode, which removes frost from the coil in about 15 minutes. The heating effect may not be sufficient if the outside temperature is too low.

Why is my LG S4UW24K2RZD still running after I turn it off?
- G
  Gabrielle BrooksSep 6, 2025
  If your LG Air Conditioner's indoor unit is still operating after being turned off, the Auto Clean function is likely running to remove remaining moisture. Allow it to continue, or turn off the unit if you don't want this feature.

Why is my LG S4UW24K2RZD Air Conditioner discharging mist?
- L
  lisa59Sep 9, 2025
  If the air outlet on your LG Air Conditioner's indoor unit is discharging mist, it is because the cooled air from the air conditioner makes mist. When the room temperature decreases, this phenomenon will disappear.

Why does my LG S4UW24K2RZD Air Conditioner smell?
- B
  Brett JonesSep 12, 2025
  If you notice an odor coming from the indoor unit of your LG Air Conditioner, it may be due to absorbed odors like cigarette smoke being discharged with airflow. Try washing the filter. If the smell persists, contact the service center to clean the heat exchanger.
