More about this in Highlands

A broken garage door sensor stops the door partway down or refuses to let it close at all, because the opener won't finish a cycle it can't confirm is safe. The fix is almost never the opener itself — it's the small sensor unit, its wiring, or its aim that's failed. For the whole picture on garage door repair Highlands Texas, start at the town page.

What a broken garage door sensor actually does to the door

Two sensors sit low on either side of the garage door track, aimed at each other to form an invisible beam. When that beam is broken, blocked, or the sensors can't see each other because one has drifted out of alignment, the opener treats it as an obstruction and stops the door short or reverses it back open. A door that won't close, or one that closes partway and kicks back up every time, is the classic sign of a broken garage door sensor rather than a spring or cable problem.

Highlands sits where roughly a quarter of the CDP's total area is water, with most of the community built on a high bank along the San Jacinto River and the Houston Ship Channel. Sensor units mount just a few inches off the garage floor, which puts their wiring, brackets and connection points at exactly the height floodwater reaches first. Corrosion at those low connection points is a common reason a sensor tests fine on the bench but still won't hold a signal once it's wired back up in the garage.

Why a broken garage door sensor shows up after flood years

A Cedar Bayou gauge near Highlands recorded 51.88 inches of rain during Hurricane Harvey in 2017, a rainfall total that set a continental U.S. record for any tropical cyclone at the time, and the San Jacinto River hit record flood levels right alongside it. Just two years later, Tropical Storm Imelda pushed the same river past flood stage again. Homes that took on water in either event, or both, often have sensor wiring and brackets that corroded quietly over the following months, showing up later as a door that won't close on command.

A broken garage door sensor is common on older Highlands doors

Damaged sensor on a garage door in Highlands, TX: a service call at a Texas farmhouse

With the median Highlands home built in 1982, a large share of the community's garage door openers and sensor pairs are original equipment, decades past the point most manufacturers expect them to still be working reliably. An aging sensor pair on a door that old is more likely to fail from simple wear — cracked lenses, brittle wiring insulation, loose brackets — even on houses that never took on floodwater directly.

Don't force a garage door with a broken sensor to close

Holding the wall button down to force the door past a stopped point just masks the sensor problem instead of fixing it, and it defeats the reason the sensor is there in the first place. If a door won't finish closing, or reverses every time it gets partway down, get the sensors checked before relying on the opener to override it.
