I have the outdoor condenser unit dual zone 24KBTU LMU240CE and the indoor units are 12KBTU LMAN120CNS "Artcool" units.

The indoor units freeze up sometimes if the 2 zones are set to different temperatures, or just 1 unit is turned on. One line set is a little short. I have no idea if this is normal since LG provides no operating information and the troubleshooting section is pathetic.

Does anyone have any technical documents on troubleshooting these units? I get error codes CH2 flashing when the unit freezes up, then it shuts off. Gonna pay $300 to extend the unit lines if I can't find anything else.

Thanks all for your help!
