Hello, I have a torsion spring garage door. A few days ago, the door would not close and would make a grinding noise. I noticed that one of the rollers was missing at the top of the door. After replacing the roller, the door rises smoothly, but when it is being let down, I still hear the grinding noise and there appears to be quite a bit of tension on the arm that extends from the track to the base of the opener unit. It does go down, but something is not right.
The door itself is quite heavy, as it's a 2-car garage and the door is wood.
Does this sound like a track cleaning issue or something simple that I can adjust on the unit, or does it sound more involved than that?
I can email a short mpg from my digital camera if it would help.
Thanks, Dave
