My door is getting a little old, 10 years, and the side of the door began to brush against the reveal (around the upper half). Searching a bit a came to the conclusion that I have to adjust the screw on the picture:
I tried clockwise (not sure whether this is the way turn in order to bring the door towards the hinge), initially it moved hard, but after it became easy. Now I can easily twist the screw in both direction. But I can twist in both direction 5-10 turns, nothing happens, the brushing problem remains.
So I do not know, whether I am twisting the proper screw, and why is it moving so easy. Maybe it got broken?
Please help me how can I adjust the door.
