Craftsman garage door opener key pad problem
I have a 1/2 hp craftsman garage door opener that is about nine years old. It worked fine until a month ago. The first thing i noticed was the wireless keypad quit working. Changed the battery and it still would not work. Another thing i noticed was that, even tho the sensor beams were operable (green light on), the light on the motor did not come on when i walked in the garage breaking the beam. Nor did i hear the relay clicking as before. Is this and the keypad problem related? All other functions of the opener, including the light (when the door opens)and remotes work ok. What is the fix?
