How to Fix / Troubleshooting
Safety first: Springs are under extreme tension and can cause serious injury. Do not attempt spring replacement unless you are a trained technician.
- 1. Disconnect opener: Pull the emergency release and test the door balance by hand.
- 2. Inspect springs: Look above the door for torsion springs or along the tracks for extension springs. A visible gap in a torsion spring or a hanging extension spring indicates breakage.
- 3. Do not operate with broken springs: Leave the door closed if possible and avoid using the opener, as it can be damaged by the extra load.
- 4. Call a professional: Contact a qualified garage door technician to replace or adjust springs and verify proper door balance.
