my garage door developed a problem lately - when disengaged the screw locker, manually lifting it up and down, i found that lifting up is easier but harder to pull it down.  does that mean my sping beinmg over torsed?  currently the garage door sometimes going down halft way then reverse up.

如果以前都正常，问题近期才偶有发生，感觉不是拉簧过紧，从原理上看，关门过程是两面拉簧
