Have you tried gently pulling on the awning arm while someone pushes the button?
I was having a problem with my big awning not going out and the patio one working fine. I asked DW to push the button while I gently pulled on the arm and the awning came out. I have since established a maintenance schedule to lubricate the pivot points and it has been working ever since. Just a thought!
