Most garage door openers have an open and close limit control.
Garage door rolls back down.
Slipping down a few inches after opening posted by sicboy on 5 10 16 at 12 14 pm 0 0 our door squeaks like crazy every time it opens and closes so sunday night i sprayed the rollers and some of the joints with wd40.
This model looks like it is new and i would first check the balance of the door by closing the door and releasing it from the opener and lifting the door by hand to waist lever and releasing it to see if it stays in that position or if it slams to the floor.
Garage door goes up and sometimes back down by itself.
If the door stops short of closing lengthen the close limit by turning the control knob in the direction indicated usually counterclockwise.

Garage door opener problem.
They are usually on the motor housing and you access them by opening a panel or removing the housing cover.
If your garage door isn t staying open or staying closed you may need to adjust your limit switch which requires only a flathead screwdriver.
There appears to be an electric fault on the way up but it stops about 30ins from the top when it clicks and stops.
Once it slides down does it go back up and stop in the correct place if it doesn t maybe the gear or gear shaft on the motor is stripped.
It reacts properly and.
