well I unhooked the door and the opener stops on the down cycle without door attached when I hit button again it goes on forward.
Since the opener still stops without the door attached, it is safe to say that the opener is the problem. Verify that the trolley is not binding on anything in the area where it stops.The next thing to do is to take the cover off the opener. Watch the plastic gears inside the opener as you try to close it and see if some teeth are missing on the gears or if there is any binding going on or if the gears are worn down at all.
well adjusted down force now it is stopping 4-5 times on the down cycle. moved back to original setting and still does same. Yep looks like opener is crapping out.
