Hi...my automatic garage door will only open about 12 inches before it gets stop. If I open it manually, I can then CLOSE IT automatically with no problem, though.
Does anyone know if the torsion springs are both supposed to be at the same tension? The left side spring is quite loose compared to the right side spring. When I first saw this, I thought this must be the reason the door wouldn't open. However, the springs on the garage door across the street are also not the same tension (one side is noticably looser than the other) and that door seems to work fine. So maybe my problem isn't related to the springs.
Any ideas, anyone?
