picked the RV up and they did not pull refer out any, moved the thermistor to the last fin on right and said to try it. As far as the commitment to fix the the insulating material for 600.00 they claim that's what is most likely is the cause no guarantee. They said the fans are working, heat elements ok freezer cooling to -5 so theres nothing left. I used it this past weekend and 42 degrees at midnight long after the sun went down. fin temp 35. didn't seem any better. I was at the shore never got over 65 degrees outside temp during the day and mostly rain. I did hear fan or fans running once and awhile.
