More about this in Huffman
A garage door sensor not working means the opener can't confirm the path is clear, so it refuses to close the door at all, or it starts down and reverses right back up. That's the opener doing exactly what it's built to do — the problem is somewhere in the sensor pair, their wiring, or the alignment between them.

What a garage door sensor not working actually means at the opener
Two sensors sit low on each side of the track, a few inches off the slab, aimed straight at each other. When that beam is broken or the signal between them drops, the opener won't let the door finish closing — it's a safety feature, not a malfunction of the door itself. A garage door sensor not working can come from something as simple as a dead LED on one unit, or from wiring that's lost continuity somewhere between the sensor and the opener head.
A garage door sensor not working after standing water got into the wiring
Huffman has two flood years behind it in recent memory. During Hurricane Harvey in 2017, 128 homes along the East Fork of the San Jacinto flooded, and just two years later Tropical Storm Imelda sent rescue crews into the Lochshire neighborhood to pull people from flooded homes. Sensor wiring that runs low along a garage wall sits right at the height water reaches in an event like that, and corrosion inside a splice or connector can take months or years to fully fail after the water's gone — which is why a sensor that tested fine last year can go dark today with no new damage in sight.

Checking the easy stuff before calling it a garage door sensor not working
A knocked-loose bracket, a spiderweb across the lens, or direct sun hitting one sensor at a certain time of day can all mimic a wiring failure. Ruling those out first is quick, and it's why a proper garage door sensor not working call starts at the lens and the alignment before anyone opens up a connector to test for corrosion underneath.
Why Huffman's older housing stock adds to a garage door sensor not working
With Huffman's 77336 ZIP built out mainly in the 1970s and the 1990s, a lot of the sensor wiring and opener hardware in the community predates any flood event by decades. Older connectors and older insulation don't hold up to a soaking the way newer sealed units do, so a house from either of those build eras that also took on water in 2017 or 2019 is a strong candidate for a wiring-side sensor failure rather than a simple lens problem.
Don't keep pressing the opener button hoping the sensors reset on their own — that just adds cycles to a door that isn't going to close until the actual fault is found.
