I have one that is similar and when I make adjustments I bairly move that nob to the point where I'm not sure it even moved. I wait and check back in say 20 min. and if no change I do it again. It takes such a slight movement of that nob to make a big change that small changes are better.
Have you looked at the Little Giant tips and tricks? That may not be the exact name but there are lots of little things you can do. You may have to wait till this hatch is done before you do some of them but it will be good for next time.
