Are you saying that with the opener completely disconnected from the
door that the door goes up and down the full amount of travel without
any great effort in either direction and no signs of binding during
the complete distance of travel up and down and back up??

Correct.

OK - Have you run the opener from one end to the other end of its
travel, in both directions several times? Any hint of binding as the
traveler goes back and forth? Is it a chain drive or a screw drive?
Is the connecting link from the chain/screw traveler to the door
itself well-lubricated, that's easily overlooked.

Yes, several times.

No binding.

Chain.

Yes, well lubricated.

Update is following.
