Overhead Legacy:

When the door opens it sometimes falls back down part way. It hits "top"
then bounces back down rather than stopping in fully open position.

I have had it serviced twice (spring tension and limits adjusted) by local
Overhead dealer but problem persists.

Any ideas?
....

How does it "hit" top and bounce for starters, and/or what does that
mean, specifically????

I gather this is not on an opener or it wouldn't/couldn't have free
travel so...

Start w/ what type of door, spring arrangement, etc., etc., ...

Unless it's a leightweight door and you're giving it a heave when
opening it, I'm having hard time figuring out how it would "hit" top
instead of just going to the open position.

In general, the spring tension is obviously not matched w/ the weight of
the door and/or there's some other malfunction in play here.
Insufficient data to diagnose, specifically, though...

That is EXACTLY what is going on.

If he guided the door up like he's SUPPOSED to, it wouldn't bounce or
fall partway back down.
