Roof Fan Not Working - Help

I have only used my TrailManor once and the fan worked just fine. I set it up today and have power to the entire unit and am also plugged into a hardline, but I can not get my roof fan to work.

I have rasied the cover all the way up, checked the fuse, and all the lights work that are on the same power line. The roof fan still does not work. This TM is only six months old. Any suggestions?
