Why LG ZTNQ18GPLE0 Air Conditioner does not cool or heat effectively?

  Tammy MorrisAug 3, 2025
  Ineffective cooling or heating in your LG Air Conditioner can stem from several causes. The air filter might be dirty, so refer to the air filter cleaning instructions. If the room was very hot when you first turned on the air conditioner, allow time for it to cool down. Also, check if the temperature has been set incorrectly or if the indoor unit's air inlet or outlet vents are obstructed.
