I tried attaching some PDF files on this system, but the forum doesn't allow PDF files of this side. Go figure, PDFs are large files.
Anyway, if you can, go to this link:
Slideout System Power Gear In-Wall
There are 2 drop downs. Under each is everything from manuals to troubleshooting guides on this system. I don't have time to read through all of them at the moment, but will this evening. Hopefully you aren't still dead in the water at that point. Unfortunately I've never worked on this particular system, however it looks like and appears to function just like the Schwintek, also under LCI's roof of products. I know on the Schwintek, even with a fault code there is a way to do an emergency override and get the slide in. I'm sure this system is similar. A quick scan over a few of the PDF's and there are ways to override it. If you haven't yet, you'll have to locate the control box, or brain. That can be fun. Sometimes it can be in the basement, or several other places, but I can assure you it's close to the slideout itself.
