It sounds like you did a really good job! My Craftsman 1/2 hp gar. dr. opener has a red reset button on it on the l/h side as you are looking at the light/motor from the garage door opening. You have to take the light cover off to be able to see it. My reset button is on the same side as the ground wire. You might check the ground wire while you're there. I really hope that this fixes it for you (and me). I'm quite sure it will as you know your way around the garage door opener already. Good Luck and Let me Know (Please) if it fixed it or not. If I think of anything else, I'll let you know. Have a Good Day!

2 flashes indicate safety eye issue. Check you wiring and make sure it is wired correctly and check to make sure the eyes are properly aligned.

2 flashes is a safety eye issue, but you problen is most likely that the chain is not sync with the limit setting. Take the bottom off the gear and sprocket assemble and rotate center limit srew until it is in the same position as the trolley.

If the main light flashes 10 times you have a door sensor problem. Make sure the small light on each sensor is on and not flashing. Tweak them if necessary. If the main light does not flash then you can try increasing the down force just a bit. This is a control on the side of the motor unit where the small gray antenna hangs. If this doesn't work you probably have a bad IR sensor which is a small printed circuit board just in front of the motor.
