Troubleshooting


   LG Air Conditioner Heating - Only the cold wind comes out. I can’t select heating operation


    If the wind feels cold without being lukewarm, then check if the remote controller is intended for the wall mounted type air conditioner.

   Try this

   Listen for the Beeping Sound :

  • When you select the heating mode with the remote, check if you hear a beeping sound from the air conditioner.

    • If you don’t hear the sound, it means heating is not activated.
  • Check for a Mode Button :
    Look for a mode button on the remote controller.

  • Confirm the Button :

    • If the remote has a heating or heater button, it is not suitable for a wall-mounted air conditioner.
  • Image of pressing the mode button on the remote control

  • Set the Target Temperature :
    Use the Mode button on the remote to select heating and set the target temperature to 30°C (86°F) .

  • Check the Airflow :
    If you feel lukewarm air, it could be because the outdoor temperature is low , which may cause a longer pre-heating time. Let it run for more than an hour .

  • Check for Issues :
    If you’re using the correct remote for the wall-mounted air conditioner but can’t select heating, or if cold air continues to blow during heating, contact a service manager for an inspection.
