It sounds like you have the lock enguaged. When it is flashing it locks out all remote access. Hold the lock button for 3 seconds. The green light should go solid. On the issue of closing, it is most likely a safety eye issue. Hold down the wall button. If it closes it is the safety eyes. Holding the button overrides the safety eyes. Make sure that thelight on both eyes are both lit.

How do I program my Sears Craftmans 1/2 HP garage door opener


Stacy, get a ladder and climb up to the opener. The directions are there, but typically you press a button for x seconds, and then press a button on the remote. This handshakes the two units. continue for other remotes.

On the sensor for the craftman garage door opener 1 is orange and the other is green and my garage door doesn't open with the remotes


Nothing wrong with the sensors. They don't work when the door is opening anyway. Only when closing. Make sure the light in the wall control is not flashing. If it is press and hold the lock button for 3 seconds.

Do you have any other remotes and do they work? Do you have a wireless keypad and does it work? It sounds like you have a bad logic board but a little more info will help.
