I just replaced a broken sproket and drive gear on my 8 year old 1/2 HP Craftsman Garage Door Opener.
The instructions that came with the repair kit said to let it run free with the cover off then stop it and apply more grease to the gears.
My problem is that I am no longer getting any response from the motor. I hear a click and a yellow light in the back blinks until I hit the reset button then it stays a solid yellow.
The motor worked fine before I took it down. to replace the gears.
Would some please tell me if I'm missing a saftey switch or something or something else obvious and stupid.?
I took several pictures of the complete unit before I disconnected anything, so I am sure that the wires are in the right places.
