More about this in Katy
A garage door sensor won't close fault means the opener's safety beam between the two floor-level sensors is either blocked, misaligned, or wired incorrectly, and the opener refuses to complete a close cycle rather than risk closing on an obstruction it can't see clearly. This fault is one of several covered under garage door repair in Katy.
Call (346) 220-4724 to get the sensors realigned and cleared.
Why a garage door sensor won't close from the smallest interference
The beam between the two sensors is a thin, precise line a few inches off the floor, and something as small as a cobweb, a leaf, or a stray toy sitting in that path is enough to trip the opener's safety logic and block the close cycle entirely.
Ground movement and garage door sensor bracket drift in Katy
The Katy soil series carries a seasonal high water table from perched drainage, and enough gradual ground movement over the years can shift a garage slab just slightly — enough, in some cases, to nudge a sensor bracket out of precise alignment with its pair.
A garage door sensor won't close after storage changes
Rearranging stored items near the garage door track is one of the most common causes of a sudden sensor fault — something new sitting just inside the beam's path that wasn't there the last time the door closed normally. A different cause with similar signs is garage door sensor repair repair in Katy.
Reading the garage door sensor lights before calling
Solid lights on both sensor units generally mean alignment is fine and the fault lies elsewhere, like the close-force setting. Blinking lights point straight back to the beam itself as the problem.

With Katy's median home built in 2010, sensor brackets and wiring have had over a decade in many homes to loosen or degrade slightly. A garage door sensor won't close fault is almost always fixed at the sensor level, not by replacing the opener.
