After three weeks and two trips with our new 2014 34 RLSA I finally got around to working on the Hoosier cabinet door. Like many the door would not stay up, would keep closing shut.
I put a small plastic shim (you could use the wooden shims) between the small wood block that was on each side of the round plastic tube cap that contains the rolled up door. This put just enough pressure on the housing and rolled door to keep it up and in place and easily goes up and down, will stay put at any position.
