More about this in Alief

A garage door sensor won't close problem means the door starts down, stops or reverses, and the opener is refusing to trust what it's seeing at the two small lenses near the floor. That's almost always a blocked or misaligned lens, a corroded wire, or a bracket that's been knocked out of line, not a failing opener motor. This page is one part of a larger guide to Alief garage door repair.

Call (346) 220-4724 and a crew working the Alief area will find which one it is, since a garage door sensor won't close fix depends on which part is actually causing it.

What a garage door sensor won't close call in Alief usually turns up first

The two sensors sit low on either side of the track, a few inches off the slab, aimed at each other in a straight line. Dust, a spiderweb, direct sun, or something as small as a leaf leaning against one lens is enough to break that beam and stop the door from finishing its close cycle. On most calls, wiping both lenses and checking the aim solves it before anything else gets touched.

Why a garage door sensor repair in Alief often points past the sensor itself

Sensor issue keeping the garage door open in Alief, TX: showing a family the safety sensors

When the lenses are clean and aimed correctly and the door still won't close, the next thing checked is the wire running from each sensor back to the opener. On housing where 40% of the stock went up between 1970 and 1979 and another 29% in the 1980s, per the city's own planning data, a lot of that wiring and the brackets holding it have been in place for 45 years or more, and a cracked or corroded connection at either end can mimic a blocked beam even when nothing is in the way.

What Harvey flooding adds to a garage door sensor won't close problem

Safety eye problem stops garage door from shutting in Alief, TX: loading parts for the day

Roughly 11,456 homes in Alief took on water during Hurricane Harvey, one of the highest counts by raw number of any neighborhood in the Houston area. Sensor brackets and wiring mounted low on the track, right where the sensors sit, were exactly the hardware sitting in that floodwater, and corrosion from that exposure can show up years later as a connection that reads intermittent instead of failing outright — the door closes sometimes and reverses other times, with no obstruction anywhere near the beam.

Local facts behind a garage door sensor won't close call in Alief

With Harvey putting an estimated 11,456 Alief homes underwater, a share of the sensor wiring and brackets sitting low on those garage tracks corroded from that flooding, which explains why some won't-close calls trace back to a wiring problem instead of a simple obstruction.
With 40% of the community's housing built in the 1970s and 29% more in the 1980s, a large share of Alief's sensor hardware and the wiring feeding it is original equipment now well past its expected service life.
Because the city describes Alief as mostly medium-sized subdivisions of single-family homes mixed with larger apartment and condo complexes, most individual sensor calls come from that single-family subdivision side of town rather than from the neighborhood's multifamily stock.
