How to Fix / Troubleshooting

Safety first: Immediately disconnect power at the breaker. Do not attempt to operate the opener again until inspected. Risk of fire or electric shock.

  • 1. Allow unit to cool: Wait until all components are cool to the touch.
  • 2. Inspect internally: Remove the cover and look for charred components, melted insulation, or foreign objects inside the housing.
  • 3. Do not attempt partial repair: If any major component (motor, board, wiring) shows burn damage, replace the entire affected assembly rather than trying to patch it.
  • 4. Consider full replacement: For extensive damage, replacing the entire Linear opener may be more economical and safer than repair.
  • 5. Have wiring checked: If in doubt, have a licensed electrician verify the branch circuit and grounding.
