Liftmaster 8500 - help getting the cables back on the spindle properly

[lmaccaro]

Had some guys over working on the AC. I believe they were trying to open the garage manually and lifted my garage door to get into the garage (but won't admit it). Not really sure. But I came home to my jackshaft garage door cables in a spaghetti mess at the top of the door and the door released.

They were young guys who were really nice - if I can fix it myself I'd rather do that, not have to call their company and ask them to pay for a repair.

The jackshaft is keeping the spring under tension, so I think I just need to put the garage door into a position that matches the jackshaft position and hook the cables back up and be good to go. However, I have no idea what position the jackshaft is in. Does the jackshaft (and spring) think it is fully up or fully down right now? Who knows.

Does anyone have any advice as to what I need to do to get it back on the spindle in the correct position?

(I installed this unit myself so I'm somewhat familiar with it, but it was 5 years ago so I don't remember all the tricks required for this unit.)

Probably the reason you're not getting any responses is because no one wants to be responsible for you hurting yourself. If you haven't done this job yourself (rewinding the sping etc.) it's probably best to call someone who has.

My spring broke a week ago and the cables were unwound, maybe yours broke also?

As the post says, the springs aren't unwound. Jackshaft units don't work like the regular ones you are used to.

Oh, I know. I own an 8500 and a Masterforce shaft mounted opener. You're either going to have to unwind the springs and start over or hold the sping and shaft from rotating while trying to rewind the drums.
