What Fails Most Often Here
- A torsion spring that let go with a bang. The door won't rise, or the opener strains and stops a foot off the floor. Don't force it. Read about spring replacement.
- A cable unwound on one side, so the door hangs at an angle. Common once the bottom brackets rust. See our cable service.
- A door knocked out of its track by a bumper or a snowblower. Off-track repairs explain what we do.
- An opener that hums without lifting. We service Chamberlain, Genie, LiftMaster and Craftsman units and tell you honestly when a replacement makes more sense. Opener repair details.
