More about this in Friendswood

A garage door sensor not working means the door either won't close at all, or it starts down and reverses back up before it reaches the floor. That's the opener refusing to trust what the safety sensors are telling it, and it will keep doing that until the sensors are aligned, cleaned or rewired correctly. The main page on garage door repair Friendswood Texas lists every problem this site covers here.

Call (346) 220-4724 and a crew working the Friendswood area can sort out which one it is.

Why a garage door sensor not working stops the door cold

Every opener built in the last few decades has two small sensors mounted a few inches off the floor, one on each side of the door, aimed dead level at each other. If that beam is broken or the signal between them is unreliable, the opener treats it as something in the doorway and won't let the door finish closing — even if the garage floor is completely clear. A door that reverses itself or simply refuses to go down is doing exactly what it's designed to do when it can't confirm the beam is intact.

Garage door safety eye that stopped working in Friendswood, TX: showing a family the safety sensors

In older sections of Friendswood, sensor trouble that shows up during or right after a storm is often more than dust on the lens. Hurricane Harvey in 2017 flooded more than 3,000 homes in Friendswood, and any garage that took water at floor level had its low-mounted sensors, wiring and brackets sitting in that water too. Corrosion on the sensor wiring or connection points from a flood years ago can fail slowly, showing up as an intermittent sensor problem long after the water is gone. Some doors with this problem actually have garage door roller replacement repair in Friendswood instead.

Your garage door sensor quit working in Friendswood, TX: service trucks arriving at sunrise

The Frenchman's Creek section of Polly Ranch, near where Chigger Creek meets Clear Creek, took repeat flood losses severe enough that the city used a $2.6 million state buyout there. Homes in that area and others close to the creek are more likely to have had standing water reach garage-level hardware at some point, which is worth mentioning up front if a sensor issue keeps coming back on the same door.

What a garage door sensor not working call in Friendswood usually turns out to be

Most calls come down to something simple — a sensor that got bumped out of alignment, or a lens with enough dust or pollen on it to scatter the beam. But in neighborhoods with an older flood history, like Imperial Estates, where Tropical Storm Allison in 2001 exposed drainage weaknesses, and Wilderness Trails, where Hurricane Beryl in 2024 caused street flooding against decades-old drainage infrastructure, a wiring or bracket check is worth doing even if the lenses look clean, since corrosion doesn't always show on the surface.
