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!

First check your circuit breaker or fuse that supplies power to the outside unit. It's probably separate from the inside unit. Then try to turn unit on. If the fan and compressor just make a humming sound then turn it off and check the capacitor if you have a multimeter. You can also look at it and see if the top looks expanded. That's a good sign its bad, but not all bad one's look expanded. Tomorrow I will have access to an LG service manual and can let you know what the code means. Sorry I can't get it sooner. Let me know what you find.
