More about this in Sugar Land

A garage door sensor not working shows up as a blinking light on the opener and a door that reverses or refuses to close at all. The opener isn't broken in that case — it's reading a fault from one of the two small sensors mounted near the floor on each side of the track and refusing to close the door until that fault clears.

Call (346) 220-4724 and a crew working the Sugar Land area will sort out which sensor is at fault and why.

What it means when a garage door sensor is not working

Those two sensors send an invisible beam across the bottom of the doorway, and if that beam is broken, misaligned or blocked, the opener treats it as an obstruction and won't let the door finish closing. A knocked-loose bracket, a spider web on the lens, dust buildup, or a wire nicked by a lawn edger can all trip the same fault light, so the sensors get checked as a pair before anything else on the door gets touched.

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

Sugar Land and the surrounding ground are subsiding, with more than 6 feet of measured sinking between 1988 and 2016 alone. That kind of slow, steady settling is different from storm flooding — it doesn't recede, and a garage slab that's moved even slightly out of level over the years can twist a sensor bracket just enough to throw the beam off, so the sensors keep testing misaligned no matter how many times they're re-aimed by eye.

Garage door sensor not working after water got into the garage

The roughly 230 homes that took water in the Settlers Park and Chimney Stone neighborhoods during Hurricane Harvey, with up to 6 inches getting inside, are the kind of property where sensor wiring and mounting brackets near the floor can corrode quietly for years after the water is long gone. A sensor that worked fine right after the storm can still fail today from that same corrosion working its way through the connection.

Garage door sensor not working on Old Sugar Land's original housing stock

Your garage door sensor quit working in Sugar Land, TX: a service call at a Texas farmhouse

North of U.S. Highway 90A, "Old Sugar Land" still holds many of the original houses the Imperial Sugar Company built for its workers, and with the city's median home built in 1994, a fair share of the opener hardware in town is old enough that the sensors themselves — not just the alignment — are the actual point of failure. On those older setups, a garage door sensor not working complaint is as likely to be a worn-out sensor unit as it is a simple obstruction.

Don't force a garage door past a sensor fault

Holding the wall button down to force the door shut just overrides a safety feature that's there to stop the door from closing on a person, a pet or a parked car. If the opener light is blinking and the door won't close, that's the sensors doing their job — the fix is finding out what's tripping them, not working around them.
