Wow.. what a coincidence. We were out this weekend and had the exact same thing happen. DW closed and then re-opened the door and it worked after that.. So my suspicion is either a stuck switch or loose wire.. and ours is a 2013 264BH..
2013 Jayco Jayflight Swift 264BH
2002 Yukon 5.3L Vortex w/tow package
When I die, I want to go peacefully like my grandfather did–in his sleep. Not yelling and screaming like the passengers in his car.
