I just spent the weekend installing a new garage door opener, and when
I went to test it - it made this buzzer sound (Kind of like the buzzer
sound you get on a game show when you miss a question). Anyway - I
tried adjusting the wiring and looked all over the internet for
solutions - but none where found so I decided to post the solution to
help someone else out who may come across the same issue. Evidently
the bolts connecting the rail segments and the head unit need to only
-hand tightend, tightening them too much puts pressure on the screw
drive and doesn't allow it to turn. So if you have a buzzer sound, that
is the motor trying to rotate - you need to loosen those bolts on the
rail to a hand-tightend (or just slightly tightened with a wrench).
Hope this helps.
Good luck with your install.
