More about this in Santa Fe

A garage door sensor not working means the opener's blinking light, a door that won't close at all, or a door that closes partway and reverses back up. It's almost always one of the two small eyes near the floor on each side of the track — misaligned, dirty, wet, or wired loose — rather than a problem with the door itself. The main page on garage door repair Santa Fe lists every problem this site covers here.

Call (346) 220-4724 and a crew working the Santa Fe area will get it sorted.

What it means when a garage door sensor is not working

Each sensor bracket holds a small eye aimed at its twin across the track, and the two have to see each other in a straight, unbroken line for the opener to let the door close. Knock one bracket a fraction of an inch out of true, let dust or moisture sit on a lens, or loosen a wire at the back of the unit, and the opener reads that as an obstruction every time, whether or not anything is actually in the way.

A garage door sensor not working after water sits in the garage

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

Santa Fe sits on a coastal plain averaging just 19 to 27 feet above sea level, with drainage ditches, culverts and diversionary canals doing the work that natural grade can't. During Hurricane Harvey, residents described water rising through both the back and front doors of homes within about an hour, which put standing water directly at sensor height in plenty of garages. A sensor that got wet or splashed with mud in an event like that can keep giving false readings — or stop responding altogether — long after the floor has dried and everything looks fine to the eye.

Why a garage door sensor stops working on its own

It isn't always weather. A bracket gets bumped by a bike, a stored ladder, or a car pulling in slightly off-center, and the sensor's aim shifts just enough to break the beam permanently rather than intermittently. This is common enough on its own that a garage door sensor not working doesn't automatically mean anything happened to the garage — sometimes it's just a nudge that moved the eye a fraction of an inch.

Older sensors on Santa Fe's established garage doors

Your garage door sensor quit working in Santa Fe, TX: technician arriving at the home

With Santa Fe's median home built in 1998, a large share of the town's opener hardware is well past 25 years old, old enough that the original sensors and their wiring are reaching typical service life on their own, independent of any storm exposure. On a system that old, a sensor call can turn out to be corroded wiring or a failing sensor unit rather than a simple alignment fix.

Don't force a garage door past a sensor that isn't working

Holding the wall button down to force the door shut just overrides a safety system that's doing its job, even when the actual cause is nothing more than a dirty lens. Get the sensors aligned, cleaned and tested before relying on the door to close on its own again. For a garage door sensor not working anywhere in Santa Fe, call (346) 220-4724.
