And so it starts. Some of you may recall I had a garage door replaced

Well, it everything seemed OK, but last night the door started to
refuse to close. It would go down to about 12 incehs from the ground
and then reverse. In the past that meant that there were stuff haning
off the bottom of the door (spiderwebs with leaves) that interrupted
the optical line to stop the door from closing. However, in those
cases the door would make a loud clicking noise and the light would
flash 3 times. Now none of this happeded.
I unhooked the door from the automatic opener and it went down
smoothly enough. Once it was closed, the opener would run down fine
and relatch as well. I was baffled.
I put in a call to the guy who installed the door and he came out. He
apologized and said that he forgot to adjust the opener. He made some
adjustments and the door started closing again. However, now if one
tries to obstruct the door, it requires significant more force before
the door would reverse direction. I'm thinking this door made of 24-
guage steel is substantially lighter than the old wooden door? Then is
my garage door handyman trying to hide a installation flaw by turning
up the force of the closer?
Are there online specs I can look up to determine the settings on my
garage door opener and verify that they are set correctly? It is a
