Garage door opens normally but will not stay closed; immediately reverses and opens again.

Safety: Keep clear of the door path during adjustments.

• Inspect bottom seal and floor: Check for objects, ice, or buildup at the threshold. Ensure the bottom seal is not excessively stiff or folded.
• Adjust close limit: Reduce the down travel slightly so the door stops just as it contacts the floor.
• Check door balance: Ensure the door moves freely and is not springing back up due to tension issues.
• Test multiple cycles: Run the door several times to confirm it stays closed.
