Sears Garage Door Opener Problem
Like a previous post, I replaced the gear/worm shaft in my 1/2hp Sears GDO. No problems. Put unit back together. Went to try out the door & it moves 6 inches, stops then returns. Tried it again with same result. The green light on the back of the unit flashes 5 times, pauses, flashes 5 times, pauses and so on. Any ideas?? Thanks in advance.
