      All Appliantology tech members are invited to join in this workshop on all things Appliantological. 
      We have a special session planned for this one. Instead of the usual Show 'n Tell on a technical topic, we're going to post tech sheets in the comments to this Calendar Event (scroll down to see what's posted so far) and ask specific questions that can only be answered by reading the tech sheet. If you at least try to answer the questions beforehand, you'll get a lot more out of it. 
      I'll be posting a couple more tech sheets before Saturday so be sure to follow this event to keep up with the tech sheets we'll be going through. 
      Who: This workshop is only available to tech members at Appliantology.
      When: Saturday, April 27 @10:00 AM Eastern Time.
      Where: Online via Zoom
      How:

LG Mini Split LMU240CE and LMAN120CNS Troubleshooting Manuals

Recommended Posts

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!
