Garage door closes too hard, slamming into the floor.

Safety: Excessive closing force is dangerous and can damage the door or injure someone.

• Reduce down travel: Turn the down travel adjustment to shorten the close distance so the door just contacts the floor.
• Reduce down force: Turn the down force adjustment to a lower setting.
• Check springs: Inspect for broken or stretched springs; have a professional replace if needed.
• Re-test safety reversal: Perform the 2x4 test to ensure proper reversal.
