I have a Craftsman GD opener that is about 14 years old. Logic board 41A4315-6c. It won't move up or down with the wall switch or the remote. The lights will not come on with the light button on the wall switch. I do get a loud click from the motor unit when I press the normal wall switch open button and the same from the remote but no response from the motor. Safety sensors seems to be just fine. There is a green LED on the logic board that is blinks 5 times then stops for 10 seconds and repeats the 5 blinks. Does anyone know what the 5 blinks indicates? Since nothing is working except for the loud click, I am assuming the logic board must have died. Since it is 14 years old I am not sure whether it is more cost effective to repair or just buy a new opener. Any comments, solutions, or suggestions would be appreciated. It was working just fine and suddenly quit this morning just in time for New Year's. Thanks for any help you can offer.
