You should be able to switch to manual (usually pulling a cord) and see
if the door will smoothly open and close and say open closed and at the half
way mark. If not you need the springs adjusted and this should be done by
the original contractor for free. It should be part of the installation.
Messing with those springs can be seriously dangerous.

If the door does work properly in manual mode, then it is the opener and
or it's adjustments.

Background:
I had a spring break on my double garage door a few months ago, and
had a contractor replace both springs.

Now some months later, when shutting to door (/w the garage door
opener). it stops (about 2/3s down), and goes back up (seems to think
that there's an obstruction). To get the door to shut cleanly I have
to assist (pull) in it's downward travel (apply additional load to the
door, to counteract the springs).

My guess it that the "new" springs have been set incorrectly. If I try
to shut to door sans garage door opener, it takes some effort to pull
the door shut - particularly in the last 1/3 of it's travel.

Is my assumption correct - should I call in the original contractor to
adjust the springs. By the way I have tried to adjust the garage door
opener (set screws) but to no avail. Garage door opener is a Sears
brand /w rubber drive belt.

Prior to the broken spring there was never a problem closing the
garage door /w the opener.
