Gliderol garage door will not stay closed; it reaches the floor then immediately opens again.

Safety first: Keep clear of the door while adjusting limits.

Steps to keep door closed:

• 1. Inspect floor area: Check for new rubber seals, mats, or raised concrete that may stop the door early.
• 2. Adjust close limit: Move the close limit cam or reprogram the electronic close limit so the door stops just as it contacts the floor.
• 3. Check beams: Ensure safety beams are not being blocked by objects near the floor.
