We had excellent results with our awning on our '06 the first year. Then earlier this year in Palm Springs it would retract in the slightest wind. We played with the DIP switches in the control box, cleaned the wind sensor, and did everything we knew, and nothing worked for any length of time.
Finally, we took the coach to our dealer who diagnosed it and said both the wind sensor and the control box had to be changed, because they said they were matched and neither was working properly.
They replaced the wind sensor and control box under Dometic's warranty in April of this year and it's been working fine ever since.
For what it's worth -- this worked for us; don't know if it will help you.
