Symptoms
- Door stops a few inches above the floor consistently
- Door doesn't reverse, just stops
- Gap is roughly the same each time
Likely causes
- CommonDown travel limit set incorrectly on the openerThis setting tells the opener where the fully closed position is, and it can drift or be set wrong.
- PossibleTrack slightly bent near the bottomA bent section low on the track can physically stop the door's travel.
- PossibleObstruction in the track near the floorDebris buildup at the bottom of the track can block full closure.
- PossibleDoor panel or weatherstripping binding near the floorA worn or oversized bottom seal can sometimes catch before the door fully closes.
What to do
- Check the floor and bottom track area for any visible obstruction or debris and clear it.
- Inspect the bottom weatherstripping (astragal) for damage or a section that's binding.
- Locate the opener's travel limit adjustment, usually a dial or button combination described in the manual.
- Adjust the down limit slightly at a time, testing the door after each small change.
- Check the track for bends near the bottom that might physically stop the door before adjusting limits further.
- If limit adjustments don't resolve it or seem maxed out, the issue may be track-related and worth a professional look.
