First time on the site. I have a Solair retractable awning that is 20 or so years old (my guess). Currently when I press the button for the awning to go out, it doesn't do anything. After pulling it out manually with the crank, I am able to retract it via the switch. This has been going on for over a year. This weekend the switch and am still having the same issue. Motor sounds fine and functions well, but only in one direction. Thoughts?
