Possible Causes

Snapped torsion spring above door, Broken extension spring along horizontal track, Spring anchor or cable failure, Door locked by slide lock

How to Fix / Troubleshooting

Safety first: A broken spring makes the door extremely heavy. Do not attempt to lift a double-wide door alone. Do not attempt to replace torsion springs yourself unless you are trained and have proper tools.

  • Disconnect opener: Pull the emergency release and attempt to lift the door a few inches. If it is extremely heavy or will not move, stop.
  • Inspect springs: Look above the door for a torsion spring with a visible gap, or along the tracks for broken extension springs.
  • Check locks: Ensure any manual slide lock on the door is fully disengaged.
  • Do not use opener: Running the Guardian opener against a door with a broken spring can destroy the opener.
  • Call a professional: Contact a qualified garage door technician to replace springs and balance the door. After repair, reattach the opener and test.
