Why LG AC18BH.NSK Air Conditioner does not emit cool air?
- M
  Michael OrozcoAug 15, 2025
  Several factors can cause your LG Air Conditioner to not emit cool air. Ensure that curtains, blinds, or furniture aren't blocking the unit's front. A dirty air filter can also restrict airflow, so clean it every two weeks. In summer, it may take time to fully cool the room; use Jet Mode for quicker cooling. Also, seal any ventilation points to prevent cold air from escaping. Check if the set temperature is higher than the current room temperature and lower it accordingly. Avoid using heat generators nearby, and ensure the unit isn't in Fan Mode, which only circulates air without cooling. Lastly, if the outside temperature is too high, the cooling effect may be insufficient.

  If your LG Air Conditioner isn't working, first check if it's properly plugged in and that the power isolators are switched on. Inspect the fuse and replace it if it has blown, or check the circuit breaker. If there was a power failure, turn off the unit and wait three minutes after power is restored before turning it back on. Verify that the voltage isn't too high or too low. Also, ensure the air conditioner wasn't turned off automatically by a timer, and check the batteries in the remote controller, replacing them if necessary.

  If water is leaking from the outdoor unit of your LG Air Conditioner during heating operations, it's likely due to condensed water dropping from the heat exchanger. Contact the installer to install a drain hose under the base pan.

  If your LG appliance and smartphone aren't connecting to Wi-Fi, first, remove the Wi-Fi network from your smartphone and re-register the appliance on LG SmartThinQ. Make sure your smartphone's mobile data is turned off, and register the appliance using Wi-Fi. The wireless network name (SSID) should only contain English letters and numbers, without special characters. Verify that your router frequency is 2.4 GHz, as this is the only supported frequency. Finally, ensure the router is close enough to the appliance to provide a strong signal.

  If your LG Air Conditioner stops during operation, first check the timer settings to ensure it wasn't programmed to turn off. Also, if a power failure occurred, wait for the power to return.

Why LG AC18BH.NSK Air Conditioner does not emit warm air?
- X
  xwoodsAug 31, 2025
  There are a few reasons why your LG Air Conditioner might not be emitting warm air. When Heating Mode starts, the vane may be closed, preventing airflow until the unit generates enough warm air. This is normal. Also, the outdoor unit may be in Defrosting Mode to remove ice buildup, which can take about 15 minutes. Lastly, if the outside temperature is too low, the heating effect may be insufficient.

  If the indoor unit of your LG Air Conditioner continues to operate after being turned off, the Auto Clean function is likely running. This feature removes remaining moisture inside the unit. Allow it to continue, or turn off the unit if you don't want this feature.

  If you're unable to adjust the temperature on your LG Air Conditioner, it's likely because Fan Mode or Jet Mode is selected. Switch to an operation mode where temperature adjustments are possible.

Why does my LG Air Conditioner smell?
- I
  Isaac MorenoSep 12, 2025
  Odors, like cigarette smoke, can be absorbed into the indoor unit of your LG Air Conditioner and discharged with airflow. If the smell persists, wash the filter. If that doesn't work, contact the service center to clean the heat exchanger.
