On a door this age, off-track almost always shows up one of three ways. The door hangs noticeably crooked, higher on one side than the other, because a roller has worked loose from the track on just that side. Or the door won't move at all and you can see, usually near the bottom corner, that a cable has slipped off its drum or popped out of the roller bracket entirely - that's the most common call we get from this part of the service area. Or there's a visible dent or kink in the track itself, usually from a car bumper or a bike handlebar, bent just enough that the roller can't ride through it straight anymore.
After thirty-plus winters in this cold-moderate climate, the original zinc-coated track on a 1990-built garage door in Butner is often rusted enough at the mounting brackets that a roller finally walks out of the rail on its own, no bump required. That's an age-and-weather problem more than a one-time accident, and it's worth knowing the difference before you decide whether to fix the track section or replace it outright.
Don't try to force the door back onto the track yourself. A door under spring tension that lets go while you're pushing on it is a fast way to lose fingers or crack a panel.
