I have a 1/2 hp Craftsman Garage Opener less
than a year old. Sometimes during the day
the door will stop when going down. The
hood light on the unit will flash 10 times.
I have checked sensor connections, alignment,
obstructions, door binding, down force, etc.,
with not luck. There is a green light on
the back of the ceiling mounted base unit
that flashes 4 times every minute or so. What does this mean? Are these error codes
published somewhere? Any help would be appreciated. Thank you.
