Power awning problem
I had the same issue and found that I had neglected to properly lubricate all of the moving parts of my awning. I first managed to manually pull the awning out enough to lubricate parts of the arms, and then this allowed the awning to fully extend. Then I was able to finish lubricating everything else. Since then, it has been working fine.
