FYI.....

Did you try trouble shot your self?
Mae sure all safety light are line up. If it have one,
1: Disengage the shuttle by pulling down the rope at the end of the guade rail. Make sure the shuttle is free from the door.
2:After shuttle disengaged, open the door by hand all the way up. (If door is move-able by hand, door track is no problem, and the spring also ok, otherwise door will be too heavy to move)
3:After shuttle disengaged, use remote to operates the opener. If shuttle can move in and out, then the motor or gear does not have enough torque to open the door. (It can be adjusted read the owner manual)
4:After shuttle disengaged, use remote to operates the opener, if the shuttle not moving. But you can hear the motor is running, then the reducing Gear is no good, it is a plastic or nylon gear, which easily slips, or teeth all grind up. (How old the House or the opener is? ) Good luck!!!

  • 枫下家园 / 美丽家居 / 家里garage opener打不开门, 请教有经验的是什么原因. 有没有好的师傅可以联系修理. 谢谢.
    • 最近是否曾经停电?
      • 没有停电. 感觉好像是机械的问题. 门中间的连杆在开启时可以拉动门, 可是门就是不上升, 以致于门的上端中部变形. 帮忙分析一下是什么部位出现问题,怎么修理. 或请推荐会修理的师父. 谢谢.
        • 好像和我家的问题一样。
          正常的安装,应该是一根金属横杆连着中间的拉杆和门的两边。我家的是横杆太短,只连着最左边。 右边只靠门的铁皮向上拉,时间长了,铁皮就变形,这时,门就拉不起来了。我的修复工作就是,找来2根铁杆,固定在横杆和门的右边。这样,当拉门时,左右,中间同时用力,才不会破坏门。
