Craftsman 1/2 hp opener just clicks when try to open
Our Craftsman 1/2 hp garage door opener appears to have all power to it fine. Green light is on at control pad (3 key one) and the sensor lights are on, however, the lights on the opener itself for seeing won't come on at all and when you hit the button to open the garage door or the light button it will only hear a click.......nothing else........the lock is not on and we tried to unplug it and plug it back in as well and still the same thing. It is about 10 years old. Any other suggestions?
