A garage door sensor won't close problem means the door starts down, then stops or reverses before it reaches the floor, and the opener is doing that on purpose because one of the two sensors near the bottom of the track isn't getting a clean signal from the other. It's rarely the opener itself failing — it's almost always something blocking, misaligning or corroding the sensor pair.

Why a garage door sensor won't close on a clean-looking track

The two sensors sit a few inches off the slab, one on each side, and they have to be aimed at each other almost perfectly to keep a signal locked. A stray leaf, a spiderweb, direct morning sun on the lens, or a bracket that's shifted even slightly out of line is enough to break that beam and stop the door mid-travel. Most calls for this in League City turn out to be exactly that — nothing wrong with the door itself, just a beam that isn't connecting.
