发帖数: 2744 | 1 I have Sears Craftsman garage door http://download.sears.com/own/53985e.pdf. It now behaves weird: the wall control turned to light switch, can't open the door any more. Anybody had similar issue before? Baozi will be followed if you provide useful information. Great thanks! |

点亮opener的灯是操作的第一步，问题混可能是在opener的电子线路上。你的遥控器工
作不？
俺建议你先踩梯子，把opener的电源拔了，等20秒再插回，这个reboot opener |

发帖数: 2744 | 3 I've done the power cycle already. Portable (car) control doesn't work
either. The (big) open door button behaves like light control. It will turn
the light (attached to motor) on when pressed.
I confirmed that vacation/lock button isn't the cause because I've followed
manual to reset it.
How could I test if the problem is from electric (logic) board? |

发帖数: 7371 | 4 There should be some kind of diagnostic mechanism built in the opener, at
least in the ones I have - so when you press the self-testing button on the
main unit, it will give out error code in a sequence of blinking lightings.
There cud be other things gone wrong here, like the tension spring on the
door itself. Did you try to pull the string with red handle to disengage the
opener, and manually lift up and push down the garage door? if it is too
heavy to lift, then the spring may be broken. |

ended up with replacing the entire motor. |
