Anyone own one? Know how to adjust the thing? The Genie web site has a
manual available, but it doesn't cover old models, and mine looks nothing
like the new ones.

Problem: When I hit the button (remote, or wall mounted) to close the door,
it goes a foot or so and then stops, or reverses and brings the door back
up. There is NOT a safety thing on the tracks to detect someone standing
under the door, so that's not an issue. A month ago, I had a pro install new
springs so at least the door was usable while I was pondering what to do
about the opener. In other words, this problem existed before that work was
done.


IIRC the older genies sensed an obstruction by how much excess torque
occurred during door movement. So if the motor thinks it's working
too hard it will reverse. Perhaps your springs are not "helping"
enough and there is too much load on the opener.

I also seem to recall that if the clutch was loose and slipped and
let the motor overspeed that would also trigger it to either stop or
reverse. So that's another possibility. Does it sound like it's
slipping before it stops/reverses? To adjust that on my old genies
there is a nut on the very back of the unit and that nut is threaded
onto the tail end of the motor/drive shaft along with a spring and
nylon washers. You tighten it to snug up the clutch and make it stop
slipping.
