More about this in Thompsons
A garage door chain won't close the door when the chain has slipped off the sprocket, gone slack, or the trolley it drags is disconnected from the door arm. The opener motor can be running fine and the chain still won't pull the door down because the connection between the two has failed somewhere along the rail.

Why a garage door chain won't close even when the motor still runs
The chain rides a sprocket at the opener end and drags a trolley along the rail toward the door; if the chain jumps that sprocket, stretches loose, or the trolley pin working loose from the door arm, the motor keeps turning without moving the door an inch. From outside the garage that looks identical to a dead opener, but the fix is entirely different โ it's a chain and sprocket problem, not a wiring problem.
A garage door chain that won't close after sitting near standing water

Nearly 41% of Thompsons sits under water, most of it Smithers Lake next to the W.A. Parish Power Plant, so any garage within reach of that humidity is dealing with more airborne moisture year-round than most towns this size. That constant dampness works on unprotected chain links and sprocket teeth faster than it would in a drier part of the county, and a rusted link or a corroded sprocket tooth is a common reason a garage door chain won't close smoothly here even on a door that's otherwise in decent shape.

Garage door chain problems tied back to Harvey in Thompsons

When the Brazos River burst its banks during Hurricane Harvey, Thompsons flooded within hours and most homes in the town took on water, opener rails and chains included. A chain drive that sat submerged even briefly can carry rust inside the links that isn't visible from the floor, and that kind of hidden corrosion is exactly what makes a chain bind, skip a sprocket tooth, or finally give out years after the water receded.
What a garage door chain won't-close call in Thompsons usually turns out to be
With only 114 housing units spread across the town at one of the lowest housing densities in the Houston area, most of Thompsons' garage doors are older installations that have had years to build up chain wear, rail rust or a loosened trolley connection, rather than newer hardware still under its first years of service. That age, combined with the humid subtropical climate pressing on every metal part in the garage, is why a garage door chain won't close cleanly on the first try in this town โ sprocket, rail and trolley usually all get checked together.
