Why is my LG Air Conditioner not blowing cold air?
- A
  Angela FigueroaAug 17, 2025
  If your LG Air Conditioner isn't emitting cool air, ensure that curtains, blinds, or furniture aren't blocking it. Clean the air filter every 2 weeks. In summer, use Jet Mode for faster cooling. Check for air escaping through ventilation points and set the desired temperature lower than the current one. Avoid using heat generators nearby and ensure the unit isn't in Fan Mode. The cooling effect may not be sufficient if the outside temperature is too high.

  If your LG Air Conditioner isn't working, first, check if it's plugged in and the power isolators are switched on. Replace the fuse or check the circuit breaker if a fuse has blown or the power supply is blocked. If there was a power failure, turn off the air conditioner and wait 3 minutes after power is restored before turning it back on. Also, check if the batteries in the remote controller are correctly inserted or need replacing, and ensure the voltage isn't too high or too low. Finally, verify the air conditioner wasn't turned off automatically by a timer; if so, turn it back on.

  If your LG Air Conditioner stops 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.

  If water leaks from the outdoor unit of your LG Air Conditioner, it is because, in the heating operations, condensed water drops from the heat exchanger. This symptom requires installing a drain hose under the base pan. Contact the installer.

Why is my LG S4NQ18KL3QD not blowing hot air?

  Mario HarperAug 31, 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 symptom is normal. Please wait until the unit has generated enough warm air to blow through the indoor unit. If the outdoor unit is in Defrosting Mode, this function removes a layer of frost on the coil, and it should finish in approximately 15 minutes. The heating effect may not be sufficient if the outside temperature is too low.

Why is my LG S4NQ18KL3QD making noise?
- M
  Michelle FloydSep 2, 2025
  If there is noise or vibration from your LG Air Conditioner, a clicking sound when the unit starts or stops is due to movement of the reversing valve, which is normal and will stop. A creaking sound from the plastic parts of the indoor unit is due to shrinking or expanding from temperature changes, which is also normal and will stop. A flowing or blowing sound is the flow of refrigerant, which is also normal and will stop.

  If the indoor unit of your LG Air Conditioner is still operating even when the unit has been turned off, allow the Auto Clean function to continue since it removes any remaining moisture inside the indoor unit. If you do not want this feature, you can turn the unit off.

  If the temperature on your LG Air Conditioner cannot be adjusted, it may be because the Fan Mode or Jet Mode is selected. Select an operation mode in which you can adjust the temperature.

Why is my LG S4NQ18KL3QD emitting mist?

  Brian Hernandez MDSep 12, 2025
  If the air outlet on the indoor unit of your LG Air Conditioner is discharging mist, it is because the cooled air from the air conditioner makes mist. When the room temperature decreases, this phenomenon will disappear.
