More about this in Pasadena

A garage door sensor won't close the door when the two small eyes mounted low on either side of the track lose their line of sight to each other, and the opener reads that as an obstruction even when the garage is empty. It reacts the same way whether the beam is blocked by an object, knocked out of alignment, or just fogged over — the door stops or reverses either way.

Call (346) 220-4724 for a diagnosis before assuming the opener itself is the problem.

Why a garage door sensor won't close the door on a clean floor

The two sensors sit a few inches off the garage floor and stare straight at each other; anything crossing that line — a stray tool, a pet, even a spiderweb across the lens — tells the opener the path isn't clear and stops the door mid-travel or sends it back up. That single beam, not the door or the opener motor, is the first thing worth checking when a garage door sensor won't close problem shows up on an otherwise normal door.

A garage door sensor knocked out of alignment

Sensor issue keeping the garage door open in Pasadena, TX: aligning the photo eye sensors

Sensors mounted on thin brackets don't need much to go crooked — a bump from a car bumper, a ladder leaned against the track, or a bracket that was never quite tightened down. Once the two lenses stop pointing at exactly each other, the beam breaks even with nothing in the garage at all, and the fix is realignment rather than a new part. A close cousin of this fault is covered on the page about Pasadena garage door sensor repair help.

Tornado debris and a garage door sensor knocked loose in Pasadena

Pasadena has taken two tornadoes in less than a decade — an EF3 that tore through the northwestern part of the city in January 2023, damaging neighborhoods and apartment complexes before moving on toward Deer Park and Baytown, and an EF2 back in October 2015 that leveled half a warehouse within city limits. Storms of that size don't have to hit a garage directly to knock a lightweight sensor bracket loose or leave debris sitting where a beam used to run clean, and homes on the paths those two tornadoes cut are the ones most likely to see a sensor problem trace back to storm damage rather than ordinary wear.

Humidity and a garage door sensor lens

Safety eye problem stops garage door from shutting in Pasadena, TX: an evening service call

With hot, humid summers and only mild, cool winters, Pasadena's garages spend most of the year holding enough moisture in the air to fog a sensor lens or corrode its contacts over time, especially on units that have sat in the same spot for years without being wiped down. That kind of gradual fogging reads to the opener exactly like a solid obstruction.

What to check before calling about a garage door sensor won't close problem

Look for anything sitting on the floor between the two sensors, wipe both lenses down, and check that neither one has been bumped out of position — those three things clear up a real share of won't-close calls before a technician ever gets involved. When that doesn't fix it, the wiring or the opener's logic board is next in line. For a garage door sensor won't close problem anywhere in Pasadena, call (346) 220-4724.
