More about this in Alvin
A garage door sensor not working means the door won't finish closing, or it starts down and reverses back up before it ever reaches the floor. The opener is reading a blocked, misaligned or dead sensor as an obstruction and refusing to trust the close command, even when the floor in front of the door is completely clear. The broader rundown of garage door repair near Alvin explains how these jobs get priced.
Call (346) 220-4724 and a crew working the Alvin area will get the sensors reading each other correctly again.
A garage door sensor not working usually starts with the two eyes not lining up
Two small sensors sit low on either side of the door track, each one aimed dead-level at the other so the beam runs straight across the opening. If either one gets bumped, tilted, or nudged out of position โ by a car mirror, a stored bike, or just years of vibration from the door running โ the beam misses, and the opener won't let the door close no matter how clear the floor actually is.
A garage door sensor not working call after a bracket has rusted through

On older Alvin sensor mounts, the metal bracket holding the sensor to the track can corrode enough that the sensor tilts on its own weight, even with nobody touching it. That's a different repair than a sensor that's simply been knocked out of alignment, since a rusted bracket needs replacing before the sensor will hold its aim for good.

Why Alvin's humid climate works against a garage door sensor
Alvin sits in a humid subtropical climate with hot, humid summers, and that constant moisture in the air is exactly the environment that corrodes sensor brackets, pits wiring connections and fogs sensor lenses faster than a drier climate would. A sensor that tested fine in spring can be intermittent or dead by late summer just from sitting through months of humidity, without anything ever having struck it.
A garage door sensor not working near Alvin's older, lower-lying garages

The City of Alvin's storm water runs through two separate systems โ city-collected water first, then the county drainage district's ditches โ which means a garage sitting low relative to the street can take on standing water from one system even after the other has drained. A sensor mounted a few inches off the slab in a garage that's flooded even briefly is a sensor that's likely to short out or corrode at the connector months after the water is gone, long before anyone ties the failure back to that one wet afternoon.
Local facts behind a garage door sensor not working in Alvin
- Alvin's 1979 Claudette rainfall record โ 43 inches in 24 hours โ means even homes built well after that storm sit in a city where standing water in a garage isn't a hypothetical, it's already happened at a scale most towns never see.
- The split between city-run storm collection and the county reclamation district's ditches means a low garage can flood from either system, and sensor wiring near the floor is the first thing exposed each time.
- With Alvin's median home built in 1991, a lot of the sensor brackets and wiring in service today have been in place through more than one storm cycle, including Ike and Harvey.
- Alvin's humid subtropical climate keeps sensor contacts and lenses under constant moisture stress even without a flood event, which shortens the working life of the hardware on its own.
Don't force a garage door closed once the sensor stops working
Holding the button down or manually pulling the door shut past a sensor fault defeats the one safety feature designed to stop the door on something in its path. For a garage door sensor not working anywhere in Alvin, call (346) 220-4724 and get the alignment, wiring and bracket checked before the door runs again.
