I have a 2008 Monaco Diplomat 40SKQ with a Dometic double door {side by side} frig/freezer with auto defrost, well the freezer section dams up in the drain tray when it defrosts and does not drain out to the frig section and on down. The drain line from the freezer section to the frig section is clear but there is an open crack in the line just as it enters the frig section. I don't know if that could be the problem but it is very hard to get to. I use a blow dryer and clean it out about every week but it should drain out and not freeze up. It auto defrosts on a daily schedule. Anyone have a solve for this problem or suggestion. HELP!!!
