I had a problem when the opener tried to open the door and it would go
up so far then drop...I bought a new carriage assy and now it will go
NOW: It worked fine for a couple of turns...now when I try to open the
door, it will go up so far then just stops it doesnt reverse
itself...just stops....then I will push the button (remote or garage
button) for it to go down, and some times it will go down and sometimes
it will just stop.....it does not stop in the same places...it appears
to be random...going up or down doesnt seem to matter.
It does this EVEN if I disconnect the door.
I can easily open or close the door manually, but the opener wont.
Any thoughts or ideas?
BTW: This came with the house...I do not have a manual...
