-I have a 2-door garage doow with a single torsion bar above.
cables came loose. noticed pulley too close to support so had to move it. Have tried to tighten cables but they still stay loose.
Does this mean the torsion bar needs to be adjusted (not by me) or is there some trick to tightening the cables?
Had new torsion bar installed 3 years ago and replaced opener six months ago. (FYI)
Noticed that door must be rubbing occasionally against support edge of wall. (FYI)
