I been thinking about Garys misfortune. What holds an electric awning closed. Is it an electric brake attatched to the motor?
I have an electric tarp and it is so equiped. If the motor had no brake the tarp would not stay tightly retracted, also when the electric brake is malfunctioning the thing would slowly unroll and open up and begin to catch air. This could be happining on these awnings if so equiped.
Never had one but I think something on Garys awning failed and broke, I don't think it would have happened if not.
Just a guess, great topic, great potential seminar those auto tarps.
