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!

What does the code on the screen mean flashes between ch and 05 ?


CH 5 on these units indicates a communications error between the indoor and outdoor units. Generally, it will require a replacement outdoor board assembly to repair it. Lookup LG parts on the internet or ring them for your nearest Agent or parts. 800 243-0000

Atwood 10 gallon H2O heater- replaced thermal couple and electrode spark and sensor but heater comes on with switch, heats water for 10 to 15 mins then burner goes out. Can hear a couple of switching...


I'd check that ECO and thermostat discs are making contact properly with tank.Just peel back foam cover on outside of tank that has ECO and THERM marked on it. If they are installed correctly, replace them.
