This relates to something I intended to add here earlier. Driven by my obsessive (anal?) nature one of the first things I worked on when I got my new Interstate was to gather as much information as I could about the vehicle and its components. I built a list of every Airstream installed component I could identify, I mean everything! The list includes the model number and serial number where possible. Then I went to the website for each manufacturer to harvest product documentation, usually in pdf form. I have all the available Airstream and Sprinter documents too. (Don't get me started on all of the documents/drawings that AS should make available but doesn't!)
These files live on the laptop I have with me on the road. Many of the pdf files are searchable which often makes finding something much faster than looking through a paper document with several hundred pages. This is no small effort but it does make life easier when I need to troubleshoot a problem or replace/repair a component.
Re. your awning problem, the manufacturer probably has documentation available online that may be helpful. Maybe the sensor is adjustable. Or there may be a user forum where other users have posted useful tips.
Good luck with it,
