Re:
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!
