Try sutting off the power to both units. This may reset the unit. Check out the service manual at LG website www.lgusa.com. Go to their support page and put the model number in. Remove and replace the batteries in the remote. If there is a communication error, the inside unit will display 3 flashes. If all else fails, call LG at 1-800-243-0000. Good Luck!

The model number would be on the right hand side of the outdoor unit and same on the indoor unit if it is a midwall split. If it is a flat cassette cieling type you may need to open the grill, which is simply two little levers either side of the grill, and the grill will swing open. Without the model number it is difficult to give accurate info. However, I can offer the following. One, check the condensate drain. You can just blow into the drain pipe from the outside and this sometimes clears clogged mud in the drainpan. Or two, error reading can also come from phase failure (in the case of a three phase unit) or power related problem. This can be solved by switching off the mains and then switching on again to reset. If you have a phase failure you would need an electrician to confirm that the power supply is good. Unless you have a volt meter.

You do not mention the model, I presume that it is a cassette, in which case the float switch is located in the indoor unit. You have to remove the cover which is 4 screws. First make sure all power supply is turned off. Then remove the drain pan which surrounds the fan blade. You will see in one corner of the unit a slightly deeper part of the drainpan, this is the corner where both the condensate pump as well as float switch is located. Before you do any of this, give a serious blow into the drain pipe from outside and this may dislodge any sludge which may be causing the floatswitch to stick. You can also pull out a rubber plug which is under the pump on the drainpan.
