Possible Causes

How to Fix / Troubleshooting

Safety: A door that is hard to move manually is dangerous. Do not continue to run the opener.

  • Test manual operation: Pull the emergency release and move the door by hand. If it is heavy or sticks, stop and call a garage door professional to service springs and hardware.
  • Inspect tracks: Look for bent tracks, obstructions, or misaligned track brackets.
  • Check trolley and rail: Ensure the trolley moves freely along the rail and that the rail is straight and securely mounted.
  • Lubricate: Lubricate rollers, hinges, and bearings with a silicone or lithium-based garage door lubricant.
  • Re-test: Once the door hardware is corrected, clear the error by cycling power and test the opener again.
