Why is my LG Air Conditioner not emitting cool air?

  If your LG Air Conditioner isn't emitting cool air, ensure that curtains, blinds, or furniture aren't blocking the unit's front. Clean the air filter every two weeks. If the room temperature is high, use Jet Mode for faster cooling. Also, check for air leaks and ensure the set temperature is lower than the current room temperature. Avoid using heat sources nearby and verify that the unit isn't in Fan Mode.

  If your LG Air Conditioner isn't working, first, check if it's properly plugged into the outlet and that 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, wait 3 minutes after power is restored before turning the unit back on. Also, ensure the batteries in the remote controller are correctly inserted or replace them. Finally, verify that the unit wasn't turned off automatically by a preset timer.

Why is my LG S4NQ24K23AE not emitting warm air?
- F
  Frank LewisSep 2, 2025
  If your LG Air Conditioner is not emitting warm air, it could be normal. When Heating Mode starts, the vane is almost closed, and no air comes out until the unit generates enough warm air. If the outdoor unit is in Defrosting Mode, wait approximately 15 minutes for it to finish removing frost. If the outside temperature is too low, the heating effect may not be sufficient.

  If the indoor unit of your LG Air Conditioner is still operating after being turned off, the Auto Clean function may be running. This feature removes remaining moisture inside the unit. Allow the function to continue, or turn the unit off to disable it.

Why is my LG S4NQ24K23AE making noise?
- S
  Savannah RoySep 7, 2025
  If you hear noise or vibration from your LG Air Conditioner, a clicking sound when the unit starts or stops is normal due to the reversing valve. Creaking sounds from the plastic parts are due to temperature changes. Flowing or blowing sounds indicate refrigerant movement. These are normal symptoms and should stop over time.
