Got an older model Genie screw drive garage door opener (IS, ISL, IC

I know that if the object-sensor safety electric eye is obstructed,
the door reverses immediately after it starts down-- but I can't
figure out what would cause it to reverse at the one-foot level.

The opener has worked fine for years. The stop-activation levers for
raising and lowering haven't moved and are in the correct place, I
haven't touched the closing force or other adjustment screws on the
motor head, and the tracks and rollers appear OK too.

Ideas?




If you disconnect the opener and raise and lower the door manually, do
you notice any binding at 1 foot level?

No, seems OK.
