More about this in Alief
A garage door sensor not working means the door won't close on command, or it starts down and reverses right back up before it ever touches the floor. The opener isn't broken in that case — it's refusing to close because it thinks something is in the way, whether or not anything actually is. The overview of garage door repair Alief is the place to start if the problem is unclear.
Call (346) 220-4724 and someone working the Alief area can get the sensors reading correctly again.
What a garage door sensor not working call usually turns up first
Two sensors sit low on either side of the door opening, and they have to be staring straight at each other for the opener to allow a close. A knocked bracket, a coat of dust, or a sensor wire that's been nicked or pinched over the years is enough to break that alignment, and the opener reads it the same way it would read an actual obstruction — it stops the door rather than risk it.
Why a garage door sensor keeps failing on the same door
If the sensors have been realigned before and the problem keeps coming back, the bracket itself is usually the weak point rather than the lens. A bracket that's bent, loose, or mounted on a track that's shifted slightly will throw the sensors out of line again every time the door gets bumped, even after a clean fix the visit before — that's a garage door sensor not working pattern worth mentioning on the call.
Alief's growth and flood history behind a garage door sensor not working call
Alief's housing stock is 40% built in the 1970s and another 29% in the 1980s, which means a large share of the sensors, wiring and brackets in the community today are running on hardware that's been in place for 45 years or more. Original wiring runs and older mounting brackets on doors from that era are more likely to have worked loose or corroded than anything installed in the last decade. Another page here goes into garage door roller replacement in Alief, TX in the same detail.
That matters even more given what happened during Hurricane Harvey, when an estimated 11,456 homes in Alief took on floodwater. Sensors are mounted low, often just inches off the garage floor, which put a meaningful number of them directly in that water. Corrosion inside a sensor eye or along its wiring doesn't always show up right away — it can take years to fail, which is part of why a sensor problem on an older Alief home doesn't always trace back to something that happened recently.
Alief's population climbed from 41,820 in 2000 to 119,598 by 2017, and that growth landed in waves rather than spread evenly, which means a large number of openers and their sensor pairs across the community are the same age and reaching the same point of wear at roughly the same time.
Don't keep trying to force the door closed on a bad sensor
Holding the wall button down to override the sensors just pushes a door through a safety feature that's doing exactly what it's supposed to do. If the sensors are actually misaligned or failing, that habit either damages the opener trying to force a close it's built to refuse, or leaves the safety feature bypassed on a door that really might close on something someday.
