I have an 8' single garage door that has low clearance. So I installed
Wayne Dalton iDrive opener (for torsion spring).
It went great, and worked great for about a month. But now, it seems to
be binding (the opener itself, not the door or the bar, etc).
Last night I closed it and notice it didn't close and the cables came
off the pullys. Darn.
So, fixed that and returned the torsion spring. Then tried opening it
by hand to see if it was binding. Sure enough, about 3/4 of the way up,
it binds. Even with the door opener release engaged (so you can
manually open it).
I took both gear sides off (the metal part that slides onto the motor
and turns the bar). Opened great. Tried putting only one side on each,
bound with either side on. Only opened without them attached to the gear.
The only thing that has changed is the weather. It's down in the single
digits now, below zero at night. I don't think this could be the issue.
The garage itself is heated and normally stays at 50 degrees F.
Any ideas? I don't see how it could bind 3/4 of the way up and when the
release is activated. The motor and bar have already made many full
revolutions by then...
Any ideas? Or call tech support and just have them waste my time? Or
exchange the unit? (bought at menards)
