Keep in mind that auto resetting breakers wear out. I recently learned this and it took a couple of days to figure it out. Replaced the breaker and all is working well again. My problem was that when bringing in my power awning one evening, it wouldn't move. The slide that is run from the same breaker wouldn't move either. New breaker - problem solved.
I almost forgot, there is a auto resetting breaker inside the controller for the awning and slides. It has a auto resetting breaker in it also. Not knowing for sure which was at fault, the one inside the controller or on the Jayco 12v panel, I replaced them both. They were approx $3.00 each so no big deal.
I full time and this breaker failure happened 2 1/2 years continuous service.
