Yeah, we need to know what the question is before we can give the clearance to post.
LOL:laughing: first the Overture, I have a 3 yr. old 12'x12' with a 8500 Liftmaster opener, guess they call that a Jack-shaft style, one problem or another every year IMO due to bad installation by the door Co. that gave a tail light guarantee.
Wake up time for the movie. What I did> Last week the door started binding when it got almost down then reversed because one cable spool slipped a little, I pulled the door down, unwound BOTH springs, got the door nice and level, put tension back on BOTH cable spools and really tighten down the bolts on the spools, re-wound both springs, tighten those bolts down good. Door goes up&down good, stays halfway.
Problem> With the door up, opener engaged, then push the opener button, the door starts to come down about 6", then the cable slacken's taken tension off the >Cable Tension Monitor< then the door reverses back up. Now the ten dollar Question, where is the cable slack coming from when the door starts to come down around the corner? When I pull the door down by hand, after the first 6-10 inches, the cable stays tight rest of the way down holding the full weight of the door.
Solution A> get free input from TBN) (Solution B> By pass the Cable Tension Monitor,) (Solution C> Get another door Co. to come fix it $3-$400.00,)
(Solution D>Elect Donald Trump, get a door Co. to fix it, and make Mexico pay for it.:thumbsup: Did I get the clearance to post?:laughing:
