In our kitchen, one inside corner of the base cabinets has a lazy-susan type fixture. It is the kind with a fixed right-angle type door (not the hinged kind) where 2 3/4 circle shelves are attached with screws. The assembly turns on a pole in the middle; to turn it you just neeed to push on one of the outer doors.

Several months ago we tried removing the shelves to see how we could adjust the central post, but couldn't find anything we could change. We ended up attaching the outside doors higher up to compensate, so they could swing free of the frame again. But now it's dropped down again and the doors are stuck behind the frame again.

I was struggling with my corner cabinet lazy susan too. I had to take it apart and remove it so a plumber could get to a drain line behind it. When I put it back together its doors were dragging on the cabinet bottom. It turned out the trick for me was to loosen the set screw at the bottom of the vertical post (but on TOP of the bottom shelf), then lift the whole thing up a little bit, which allowed a sliding post within the center post to slide down. After the sliding post slid down I tightened the set screw, thus raising the whole assembly enough to clear the cabinet. The picture in the attached link shows what my set screw looks like.

For some reason the whole assembly is dropping gradually to the point where the doors, that should be outside, are stuck inside the frame. That means it can't be closed.
