We don't use our heater very often since we are in Texas . But with a two week stint in 337RLS we turned it on and it was weak. I went in the cabinet drawer and peered in to find the main duct disconnected (see the pic). We most likely are taking the rig back to our dealer for Warranty repair but was just checking if there was a quick fix for this. I couldn't figure out how to get in and being a big guy, could I do it myself.
