What to do if my LG LCN128HV4 shows a communication error between indoor and outdoor units?

If your LG Air Conditioner displays a communication error between the indoor and outdoor units, power down the unit and boot it up again. If the problem persists, it is recommended to refer to an LG trained service provider for assistance.
