I have been following your posts regarding your fridge. I have no answers for you but I would like to share my experience with you. I have a 2013 Jayco Swift SLX 185RB that has the same setup as yours. I have been dealing with fridge problems for a year and a half now, temps rising to over 70 degrees during the day and dropping to 20 degrees at night. The dealer has tried to resolve the problem with baffles and fans. Finally Jayco sent a transport to come and pick the unit up, Jayco and Norcold engineers spent a month measuring and building custom baffles adding bigger and more fans behind the fridge, then they replaced the fridge and repeated the process all over again. During this time that Jayco had the trailer there was some questions regarding the A/C unit that was mounted in the side wall of the trailer. Jayco figured out that when the A/C was turned on the air flow was disrupted from behind the fridge causing it to not cool, the A/C unit that is installed in these units is a window A/C so it will pull the condenser cooling air from the living space. So Jayco when back to the drawing board, Jayco looked at mounting a roof top A/C but due to the design of the trailer it could not handle the loads caused by a roof top A/C. Jayco tried to seal around the A/C but no luck. So they changed the baffles and fan design one more time.
When I got the trailer back last week they completely changed everything behind the fridge. Jayco extended the warranty another year and said it was good to go. We took it out last weekend and the fridge failed again. Since I have owned this trailer I have asked everyone that I came across with a trailer like mine they all say they have some sort of fridge cooling problem.
After a year and a half we have come to no other choice but to unload the unit. We are very saddened by having to trade the unit in but now it is the dealer's and Jayco's problem.
Like I said I am sorry I do not have any fixes or solutions for you but I just wanted to tell you what happened to us in hopes that you or your dealer might be able to pull some ideas out of our story.
Good luck.
