More about this in Deer Park

A garage door sensor not working shows up as a blinking opener light and a door that won't close, or a door that closes and immediately reverses for no reason anyone can see. It's almost always one of two small units mounted low on each side of the track, and either one being blocked, knocked out of alignment, or wired wrong will stop the door from closing at all.

Why a garage door sensor not working stops the door from closing

The two sensors sit a few inches off the floor and shine a beam straight across the opening between them. Break that beam — a box, a pet, sun glare, dust, a spiderweb — and the opener refuses to let the door finish closing, or sends it right back up mid-travel. A blinking light on the opener unit is usually the first clue that one of the two sensors has lost its signal to the other.

Sensors mount on thin brackets low to the floor, which puts them at exactly the height where a bike, a trash can, or a parked bumper can nudge one out of true. Once a bracket shifts even slightly, the two lenses stop lining up, and the fix is re-aiming the sensor rather than replacing it.

Older hardware around Deer Park and a garage door sensor not working

Your garage door sensor quit working in Deer Park, TX: loading parts for the day

Deer Park's median home was built in 1982, which means a lot of the town's garage door hardware — openers, sensors, wiring included — is original or close to it. Wiring insulation and sensor lenses both degrade with age, and a sensor pair that's been in place since the 1980s or 1990s is a more likely source of an intermittent "not working" fault than anything on a newer install out on the north or west side of town, where subdivisions built from the 1990s forward carry younger hardware.

Storms, power loss and a garage door sensor not working afterward

Deer Park's January 2023 EF3 tornado knocked out power across many parts of the city, and flooding from both Hurricane Harvey and Tropical Storm Allison put water into hundreds of homes in past years. Any of those events can leave a sensor with corroded wiring or a jarred bracket that doesn't show a problem until weeks later, when the door starts refusing to close on a day with no obvious cause.
