Update, We are now in Maine and the fridge is getting worse! Talked to an RV repair guy at East Coast RV, he walked me thru a couple of things that seem to have fixed the problem, I will know better Tommorow! First, I got a ladder and remove the side panel from the top of the "chimney". It seems when they built the unit they skimmed the inside with ¼ " panel and forgot that the outlet should be clear of obstructions. There was only about an 1 ½" at the top, got my saw and trimmed it so the full panel was open. Next, there is a thermostat in the fins to activate the chimney fans, I have one at the bottom which pulls cool air in, it was working ok. The fans at the top were not working even though the fins were hot. I By passed the thermostat and the fans run constantly. A couple of hours later I have solid ice cubes in the freezer. Monday I will go and purchase a new thermostat and replace the bad one! Much better than spending $5K for a new fridge!
