How to Fix / Troubleshooting
Safety first: A severely unbalanced door should be serviced by a professional. Do not attempt spring adjustments yourself.
Steps to fix:
- Check opener mounting: Ensure the opener is securely fastened to solid framing using appropriate lag screws and angle iron.
- Inspect header bracket: Verify the header bracket above the door is tight and not flexing.
- Check door balance: Disconnect the opener and move the door by hand. If it does not stay in place at mid-travel, have the springs adjusted by a technician.
- Align tracks: Loosen and adjust tracks so the door runs smoothly without rubbing.
