Hello......I am new to the group, but joined because of the specific reason you were talking about. We have a 2014 Jayco 185 Swift SLX with the exact same refer problem, works great if the A/C is not running. Ours is still under warranty and we plan to take it back to the dealer, but noticed you said you put foam around your ac and it fixed the problem. Where did you put it exactly? Around the front of the ac? Inside the cabinet? Could you post a pic? Lot's of questions I know, but this is such an aggravating problem!! Any help would be appreciated!
