Solera Power Awning
Mine did the same and I called the Solera people and they quickly blamed the motor and offered to send me a new one. They were very quick to that conclusion and solution! I never did switch them out because I found that with shore or generator power it always made it in albeit slowly. And I traded not too long after (not for that reason!). The tech told me that the reason they go out easily but come back in with difficulty is that the gas struts are trying to help it on the way out and resisting on the way in.
