1/2 HP Chamberlin/Liftmaster garage door opener question


lispeej

Question

My garage door opener has been acting weird. When it closes all the way down, it goes back up automatically. There are no obstruction blocking my safety sensors.

Another thing is that when it goes up, the quick release lever hits the unit, causing it to detach it from the belt and the door slams....very dangerous. There's some screws that you can adjust the door up/down. I've done that but it didn't seem to help.

Any other ideas.??

One thing I read that concerns me is that you said when it hits the unit and detaches the door comes down hard. The springs should be adjusted so that the door has a neutral weight. Meaning that when disconnected, if you lift the door half way up by hand it should stay there and not raise or lower on it's own.

I believe the sping(s) have come out of adjustment over time (it happends all the time) and that is causing your other issues.
