I have a 1/2 HP Craftsman GDO that is about 3 years old. All of a sudden
the door will now only open about 12 to 18 inches; the lights do not flash
at this point. If I press the button (on the wall or the remote) the door
will go down and then (usually) return back up to the 12 or 18 inch height.
HOWEVER, if I block the beam with my foot before it starts going back up, it
will return continuing to the fully open position and the lights will flash.
Any ideas? Thanks, Bill
