A door that sits or moves unevenly may have a problem with cables, springs, rollers, tracks, or another part of the lifting system. Don't keep cycling an obviously crooked door.
Look from inside the garage
With the door stationary, check whether one side sits lower, a cable appears loose, rollers are out of position, a track looks damaged, or a spring appears broken. Don't touch tensioned components.
Why does this matter?
Garage doors are heavy. When the lifting system isn't supporting the door evenly, continued operation strains other components and can create an unsafe condition.
Can I straighten it myself?
Don't try to level a garage door by adjusting springs or cables. Those components store substantial energy.
What should I do?
Stop using a severely uneven door and have the lifting system inspected. Find Local Garage Door Help
