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!

5 flashing is ' compressor drive' and check the high pressure, condenser fan motor capacitor for proper running

First check your timer on and off. If you want to reset, remove batteries from remote and power off to unit. Reset it. Now run the unit. Set temp mode once again in your remote and wait for 3 minutes. If still out door unit not working, check power line to out door unit.
