Signs to report
A hanging cable, uneven door movement or visible fraying should be checked. Stop using a door that sits crooked or appears unsupported.
A system, not an isolated part
Cable condition is evaluated with drums, springs and related lifting hardware. Replacing a cable without addressing the cause can leave the underlying issue unresolved.
Keep your distance
Do not pull a loose cable, loosen brackets or attempt to reposition the door. Keep the opening clear until a professional can assess it.
