Are you trying to open it with the REMOTE or the on panel switch?
First: Disable the wind sensor, major pain in the operating system, Dometic does not, in my opinion, know how to make a wind sensor.. Feel free to disagree with me on that issue. it is after all only an opinion.
Now try both the direct control switch and the remote
IF it no longer reacts when trying to wine up or down
Fuses exist on the control board as well as wherever they put the supply line fuse, may be in hosue, or.. Well I have four fuse blocks on this RV, Chassis Main likely does not have it nor Chassis Aux.. But the Intelletec box and the House main are my suspects.
