Definition
The federal safety standard every garage door opener sold since 1993 must meet: if the closing door touches an obstruction, it must reverse, and photo-eye sensors must stop it before contact. Together these features have made the modern opener dramatically safer for kids and pets. The catch is that auto-reverse drifts out of adjustment as springs age and force settings change. Door Serv Pro tests contact reversal and photo-eye response on every tune-up — if your door does not reverse on a 2x4 laid flat, it fails.
