I have the same problem. May I suggest you try removing the old motor before you purchase a new one. I am fairly handy with tools and I have done everything I know to remove the motor from the tube and so far I have had no luck.
Hope you have a working awning soon.
My wife and I would travel full time, but we have to sleep occasionally.
