Liftmaster 1280/2280 Opener
I have a 10 year old Liftmaster 1280/2280 Garage Door belt opener. The
belt wore out and was coming apart. I Bought a new belt off Ebay. I Removed the old belt. I quickly found that my 90 year old legs wouldn't support me on my stepladder. I enlisted the aid of my younger neighbor. I dunno what he did, but before he connected the new belt, he played with the two 'up and down travel limit' controls on the side and the two 'Force adjustmnt controls' on the back and messed them up. Then he quit on me. I need to try to correct the control settings. I want to reset them back to their starting point. They certainly are not what they were when we started. Has anyone out there had to mess with this problem? Maybe I need a 'professional' for this? Thanks Murphy |

Yes - There is a copy of the installation manual at https://www.scribd.com/doc/268502784...een&from_embed and other places of which I have had a downloaded pdf copy. As I read it, the 1280 has two controls for door travel distance up and down and two other controls for the force put on the door as it goes up and down. It talks about one control knob turn equals 2" of door travel. The thing is - right now the new belt is not on the opener at all. Neither is the old belt. Ergo, the 'gear' on the top of the motor is not engaged. When I press on the remote to run the opener, the 'gear, runs, naturally. But it won't stop (unless I press on the remote again). That 'gear' always spins in the same clockwise direction tho, so I fear that if the belt were connected to the 'gear' and the slider on the track, the belt would break when when the slider reaches its limit (ie the door is closed). And so, I fear to go on. Help? Murph |

I thought jr put the new belt on? Why did he start fiddling with the adjustments? Was it working correctly before? Seems if it was working, one would just replace the old belt without screwing with anything else and it should work as it did before. If it didn't, maybe he screwed something, like a sensor, while changing the belt. I can see as a last step, fiddling with the sensor adjustment, if needed for some reason. Is the door balanced, moves freely when disengaged? |

All the relative Youtube videos say just that. But my old belt broke some time ago, and the motor kept running st the time with the belt and slider mechanism amok. So I have no idea where things were. That said, when my neighbor said and did what he did (adjusting the sensors) I couldn't see what he was doing exactly because he was on the ladder, and I was on the floor, as I said before. He said he knew what he was doing. Blind faith got me in trouble. I would really like to be able to try the sensors to base settings (ie factory settings), and try from there. Like, u know, at zero. minimum, all the way clockwise, or some such. Murph |

But if the motor does not stop, then I was afraid when the belt reached the end of its travel length, wouldn't the new belt just snap in two or at best pull apart? Maybe if I stood there with thumb on the remote 'on' button to try to stop the damned thing (assuming it would)? Why is this so hard? Maybe I should just call Liftmaster on 1-800-578-5880 tomorrow?

Thanks Murphy If you get the kid to disconnect the traveler arm from the door and then remove two bolts from the powerhead that hold it to the ceiling brackets, the kid can then pivot the powerhead down to waist level so it's easier for you to work on. Sounds like something to try. Wud at least get me off the damned ladder. If I just knew how the up and down travel limit controls and the two Force adjustment controls were set when new from factory, then maybe it all wud run right when connected to the belt assembly. Otherwise I fear the motor will pull the new belt apart. I have no way of knowing what stops the motor 'gear' on the top of the motor from pulling on the belt. Does it stop when the belt moves a prescribed distance (ie travel limit)? Or does it stop when the belt pulls against the 'gear' pull? I have no idea. I am surprised the factory settings for the controls aren't specified somewhere. It probably matters. I need to find out what a pro wud charge me to do all this? Thanks Murph |
