I have a Dometic Two Step patio awning from 2007 (Model # 814BN17). The motor stopped running with awning extended. Before new motor arrived, a wind storm came up and bounced the awning around before I could manually roll it back up. Now the new motor works fine but the roller does not roller up or down when the motor is running. I can manually roll the tube back and forth.. Thinking it might be the spring in the torsion assembly. Or could it be something else? would like to get a better idea before calling for a repair.
