Sounds like to me that PCB connection has broke lose from it's solder
connection. Have a skilled electronics friend resolder the connection to
the PCB board for you.

About a month ago my Liftmaster 1265 stopped running. It would just hum
for
about 2 seconds and stop. Liftmaster said the limit switch has been
overrun, so I played with that. When I move the limit back, the opener
hummed for 2 seconds, paused, and then hummed for 2 seconds with a
slightly
different pitch.

Someone here said the problem was probably a leaking capacitor. I took
the
cover off, but the capacitor looked fine. But when I touched the
capacitor
the opener suddenly started running. It was okay for 2 days, then stopped
again. I touched the capacitor again and it ran okay for 5 minutes, then
stopped. Now touching does not help.

I figured there was loose wire, but I sure can't find one. Liftmaster
says
it is probably a bad capacitor for $20; and if not that, a bad logic board
for $85.

Does a bad capacitor make sense? Could touching a bad capacitor make it
run
for a while? Obviously they won't be taking the capacitor back if it
doesn't help.

This is so so frustrating.
