Garage door safety

Garage doors and springs store a lot of energy. A door that will not open, a loud snap, or a door that slams down are reasons to stop using the opener and call a local pro from a directory like GarageFix Finder.

Do not DIY a broken spring

• Torsion and extension springs are under high tension.
• Winding cones, cables, and drums can release suddenly.
• Unplug the opener before anyone inspects the door tracks.
• Keep kids and pets away from a door that is off-balance.

Quick homeowner checks

• Photo-eye sensors should sit facing each other, usually 4 to 6 inches off the floor.
• The auto-reverse test: a 2x4 on the floor should make the door reverse.
• Look for a frayed lift cable or a gap in a torsion spring.
• If the door feels heavy on the emergency release, the spring is likely the issue.
