Possible Causes

Loose rail brackets or header bracket, Bent or misaligned door tracks, Worn rollers causing wobble, Opener not securely fastened to ceiling joists

How to Fix / Troubleshooting

Safety first: Support the opener and door while adjusting brackets. Do not loosen structural fasteners without proper support.

  • Tighten rail and opener mounts: Check the header bracket above the door and the ceiling mounting straps for the Marantec opener. Tighten all lag screws into solid framing.
  • Inspect door tracks: Ensure tracks are plumb and parallel. Loosen mounting bolts slightly, adjust position, and retighten.
  • Replace worn rollers: If rollers wobble or have flat spots, replace them with high‑quality rollers.
  • Test operation: Run the door and observe. Minor vibration is normal; excessive shaking should be reduced significantly.
