Craftsman Garage Door Opener
I just saw an earlier post that outlines the same problem that I am
having. My garage door doesn't want to go down. It will start to close, go down a few inches and then go right back up again. Once it does this the lights will blink as if the sensors are obstructed yet they are not. I have been careful to clean the sensors of any dirt, cobwebs,etc. and I have made sure that there is nothing obstructing the sensors as well. I have had this problem occaisionally in the past couple of months but it seems to resolve itself on its own for no apparent reason as if it has a mind of it's own. I believe that the garage door is approx. 9-10 yrs old and I have an aluminum door. One note to mention: About four months ago I closed the garage door and the garage door buckled in the center due to an improper support on the door that snapped. At the time, a technician came out and fixed the door and adjusted all of the up-down balances and oiled the door. Any help with this would be greatly appreciated!! :-) Thanks! |

Also disconnect the door from the opener and verify that it moves
freely, with minimal force. It should stay put, or just about so, at mid-span, when let go. |

I'll reply to both trad and the op. First, trad; is it a wood door? I remember at my parents home we had an 8' and a 9' manual open doors, when the weather turned wet, the doors seemed to double in weight. They were well painted, but they sucked up moisture like a sponge. Second op; There is an adjustment for downward force that may need a partial turn. The procedure in the book says; place a 2X4 on edge under the door and adjust it so it reverses when it hits. I'll add to that; so it just barely reverses when it hits. |
