More about this in Aldine

A garage door sensor not working means the door either won't close at all or reverses back up the second it starts down, because the opener can't confirm the path is clear. Nine times out of ten it's one of two sensor units near the floor, or the low-voltage wire running to them, not the opener itself. The town-level guide to 24 hour garage door repair Aldine covers every common fault in one place.

Call (346) 220-4724 and a crew working the Aldine area will find which sensor is the problem and fix it.

Why a garage door sensor not working stops the whole door

Two small sensor units, one on each side of the track a few inches off the floor, have to see each other in a straight line before the opener will let a door close. Knock one out of alignment, get a smear of dirt or dust across a lens, or run direct sunlight into the beam and the opener reads it the same way it would a car parked in the path — it stops the door or sends it right back up. Nothing about the spring, cable or motor has to be wrong for this to happen.

If both lenses are clear and lined up but the door still won't finish closing, the wire feeding the sensors is the next thing to check. That's a low-voltage line running along the bottom of the track to a small board in the opener, and it's an easy thing to nick, pinch or let corrode without ever noticing until the door stops responding.

What a garage door sensor not working call in Aldine tends to run into

Aldine's housing stock has a median year-built of 1975, which means a lot of these sensor pairs and the wiring behind them have already been through at least one replacement cycle, if not more. Older brackets crack, older wire insulation cracks too, and a sensor eye that's twenty or thirty years newer than the door it's mounted on can still be the original unit from whenever the opener itself was last swapped.

Flood exposure and a garage door sensor not working

Your garage door sensor quit working in Aldine, TX: walking the homeowner through the finished repair

Sensor units sit low, right at the height water reaches first. Over 60% of houses in the Aldine area were damaged by Hurricane Harvey in 2017, and the Houston Chronicle reported residents were still recovering more than a year later — that kind of ground-level water exposure is exactly what corrodes a sensor's wiring and connector pins long after the flood itself is a memory. In the Allen Field subdivision north of East Aldine, homes and mobile homes are raised 6 to 8 feet off the ground specifically because the flooding there keeps coming back, which is the same reason a sensor pair mounted at floor level on one of those properties is worth checking for corrosion even without a recent storm to blame.

Don't keep pressing the button on a garage door sensor not working

Forcing the opener past a sensor that's telling it something's wrong doesn't fix the sensor, and on an older Aldine opener it can push a separate problem into the mix before anyone's had a chance to look at the real one.
