How to Fix / Troubleshooting

Safety first: Disconnect power and release the door from the opener before working on tracks. Use proper supports if the door is open.

  • Operate door manually: With the opener disconnected, move the door slowly through its full travel. Note any tight spots or binding.
  • Inspect tracks: Look for bends, kinks, or misalignment in the vertical and horizontal tracks. The tracks should be plumb and parallel.
  • Adjust brackets: Loosen the track mounting brackets slightly and tap the track into correct alignment using a rubber mallet. Retighten bolts securely.
  • Check rollers: Spin each roller by hand. Replace any that are cracked, wobbly, or seized with compatible nylon or steel rollers.
  • Re-test with opener: Reconnect the opener and test. If the door now moves smoothly, the reversal issue should be resolved.
