How to Fix / Troubleshooting

Critical safety warning: Do not attempt to adjust or replace torsion springs yourself unless you are trained and equipped. Springs are under high tension and can cause severe injury.

  • Test balance: With the opener disconnected, lift the door halfway and release. If it falls or rises quickly, the springs are not balanced.
  • Inspect springs and cables: Look for a visible break in torsion springs or slack cables off the drums.
  • Do not rely on the opener: A Nice opener is not designed to lift an unbalanced door. Continued use can damage the motor and gears.
  • Call a professional: Contact a qualified garage door technician to repair or replace springs and rebalance the door before using the opener again.
