I have the same problem in my 2018 View 24J. We bought it in November and the awning has been working fine until this week. The awning tries to extend, but just rolls back up again, even when holding the "Out" switch. I'm going to call either Winnebago customer service or the local (Fayetteville, NC) Carefree service rep to troubleshoot the problem. Will also be monitoring this thread and let you know if there is a good solution vs replacement.
