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

What Triggers The Reverse

Every opener built in the last few decades has to stop and back away if it senses an obstruction, and it checks two things: a beam between the small sensor eyes near the floor, and a close-limit setting that tells the opener how far down is too far. If either one trips, the door backs away instead of finishing its cycle. In Richardson that beam gets blocked more than most owners expect, especially in garages packed tight along Cottonwood Heights driveways.

The sensors sit low on purpose, roughly six inches off the slab, which puts them at the height of stray leaves, a parked bike, or a shifted storage bin. A spider web strung across the lenses overnight will do it too. Wipe both lenses with a dry cloth and check that the small indicator light on each one glows steady, not blinking, before assuming the opener itself has failed.

When The Frame Is The Cause

Look at the top corners where the door meets the frame. If one side sits noticeably higher, or the weatherstripping gaps unevenly along the jamb, the opening itself has shifted. Richardson's clay-heavy ground swells and dries in cycles, and older slab homes near Canyon Creek or Prairie Creek can settle enough over the years to pull a frame out of true. A sensor can be aimed correctly and still read the door wrong if the track it rides no longer lines up square with the floor beneath it.

A door that reverses at roughly the same spot every single time, rather than randomly, points toward the frame rather than the electronics. Try the door on a dry week versus a wet one; if the reversal point changes with the weather, clay movement under the slab is the more likely driver than a sensor or a limit dial that simply needs a quarter turn.

Checks Before Calling For Service

Before booking a repair, sweep the garage floor between the sensor posts and confirm nothing taller than a curb sits in that path, including a hose reel or a bin left near the Duck Creek side of the driveway. Then watch the door close once more. If it still reverses at the same height with a clear path, the limit setting or the sensor wiring itself needs a hands-on check rather than another wipe-down.

Homes backing onto Prairie Creek or sitting on a low corner of a Richardson street grid sometimes see more moisture swing at the slab edge through spring storms, which can accelerate the kind of frame settling described above. That is worth mentioning to whoever inspects the door, since it changes whether the fix is a sensor adjustment or a track realignment at the frame.
