Just purchased a 2016 Newmar Ventana 4037 LA.
I Figured out how to winterize the systems with the exception of the ice maker lines.
I air blew the entire system hoping the ice maker, left in the make ice position, would get the line blown clear. Then when I introduced the anti freeze throughout, still no pink stuff in the ice tray. ( I air blow, then antifreeze, so as MURPHY doesn't show up after winter!)
How do you winterize the ice maker line to an all electric residential refrigerator, when no outside access panel is available?
Need some advice quickly!
