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!

Generally when an ac trips the main breaker and the breaker its self isn't bad, the compressor is going bad or is bad. To check you will need to do an ohms test on the compressor. If you get a reading of less than infinite, then the compressor is bad. You will need to test every lead going to the compressor which is usually 3 unless you have a crank house heater installed but they are not typical on a small unit. If the compressor has gone bad it is possible the it took the board out as well.

Hi,
Check for 220v ACROSS the two 110v lines....if you have it on two 110v breakers instead of a two pole 220v breakers you can be feeding the same leg or the same 110v to the both sides of the connection and therefore the unit will not work...
You need to have 220v across the two hot legs or it will not work... 110v on each leg means nothing....if you have the same 110v, then more ONE of the breakers ONE notch up or down and you will have 220v then...

CH61 means Condenser coil temp high due to non cleaning of condenser/over charged gas/non condensable gas.
Clean your condenser coil. If still problem rests, due to non condensable gas also there will be high temp. Once remove the gas, flush out the system and vacumize and then do gas charging.
