My problem with the garage door opener not closing has continued for
weeks now. The door lowers to about 2/3 of the way down, then
reverses. I called one company to repair it. They charged me $85 for
the service call, and an hour later it was doing the same thing. He
came back out, made some more adjustments, then said if it continued
to act up, I'd need to replace the opener itself. The opener is less
than four years old. I called a second company to assess the problem
and they tell me the springs need to be replaced -- a mere $400 job.
At this point, I don't know who to believe. Is it likely the opener
went bad in only four years? Does this problem sound like it could be
alleviated by a new set of springs?

I had the same symptoms with mine and after cleaning cobwebs from the
sensor eyes and pointing them at each other it started working
correctly.
