    Got same length torsion spring and followed the steps for replacement of springs; but issue I see is garage door only lift up till 1 foot , stay stuck and does not move up regardless how much manual lift force I put in (in manual mode). please guide. I tried going up to 33 quarter turns (16.5 half turns) as 31 or 30 turns was not helping, rotation was clock wise for 33 quarter turns.. my old part was 218 wire x 29 long spring and new one is 225 wire and 29 long spring.

  • @djwilson48625
    @djwilson48625 Před rokem

    A couple questions: If you have multiple springs on a torsion system, do they all get the same amount of winding as say a single spring? For instance if a single spring needs seven and a half turns, would a double spring system also require seven and a half turns on each spring? I have an industrial door on my house, and that thing must weigh about 500 lb. It is kind of heavy to get lifted, it is balanced in the center, and then it wants to slingshot open once you get up over on the horizontal part of the track. Then it is difficult to start to close, is balanced in the center again, and then wants to drop to the floor after you lower it past the center.
