Why does my garage door reverse before it closes in Franklin?

Two Systems, Two Triggers

UL 325 has required residential openers to carry two independent reversing systems since 1993: a photo eye that reads a broken beam, and contact reverse that reads resistance in the door itself. A Franklin door that kicks back up before it seats on the slab is following one of these two rules, not failing at random. Knowing which one fired changes where a homeowner near Cool Springs or Westhaven should even start looking before calling anyone out.

Two separate systems can stop a Franklin garage door mid-cycle, and telling them apart saves a service call. Contact reverse depends on the down-force setting: if the bottom section meets real resistance, the opener backs off within a second or two. The photo eye pair works differently, watching for a broken beam across the opening itself, whether that's a bike left in the drive on Founders Pointe or a pet wandering through near Sullivan Farms. One reacts to touch, the other to a blocked path, and a tech needs to know which triggered before touching anything.

Photo Eyes And The Beam

When the photo eyes cause it, the door stops well above the slab, often two feet up or more, before it has come anywhere near touching the driveway. It happens the same way every time, at the same height, because the sensors are not judging force at all. They are only checking whether the beam between them is still unbroken as the door passes through that zone.

In older sections of Franklin near downtown, where garages often sit on crawl spaces and shift slightly with the shallow limestone underneath, a sensor bracket can drift out of aim over time and throw the beam off by a hair. Dust off Del Rio Pike or lawn debris after mowing near Pinkerton Park can also settle on a lens and cause the same early reversal without anything mechanical being wrong.

Contact Reverse And Force

Contact reverse only fires when the door is genuinely pressing against something, not just sensing it nearby. That means it lets the door travel almost to the slab before backing off, whether the home sits on a crawl space near Sullivan Farms or a slab foundation in a newer Westhaven build. The usual cause is the down-force setting turned too sensitive, a track that has drifted out of line, or debris caught along the bottom rail.

A track that has started binding, often from a bent rail or a bracket loosened by years of expansion and contraction, makes the opener work harder in that one spot and trips the force setting there every time. A force setting left too sensitive from a past adjustment can do the same thing on a track that is not binding at all, reversing a door that is otherwise moving without any real resistance.
