I'm not sure if it's the same situation, but I was able to crank up the tension on my door when I had similar symptoms. You have to be VERY careful not to pinch your fingers in the gears when you do it. My problem was that one side had more tension than the other did and the door was coming down crooked. I remember adjusting the tension on side to match the other. You need to use several screwdrivers and crank the tension on each side the same number of turns. I have moisture between some of my double pane windows and have had for some time now. This has left an ugly film on the glass as it dries. Is there an easy way to disassemble the window to clean the glass and than reseal.
