Might you have a manual for an old Stanley model 3500 garage dr opener? Every so often now the garage door will open by itself and the light will be blinking as when there is a problem, which there is. I don't remember what the adjustments do, like the open knob, the close knob and the sensitivity knob. Can you help/
