A garage door chain won't close call almost always means the chain has jumped its sprocket, seized with rust, or gone slack enough that the opener spins without ever pulling the trolley down the rail. The door stays open no matter how many times the remote gets pressed, because the chain isn't transferring any motion to the door at all.

Why a garage door chain won't close once it jumps the sprocket

The chain rides in a groove on the sprocket at the opener's motor head, and once that chain jumps off the groove — from age, sag, or a worn sprocket tooth — the motor keeps turning but nothing pulls the trolley or the door. A garage door chain won't close for this reason usually shows a slack loop hanging loose along the rail, visible from underneath without taking anything apart.

Chain problem keeping the garage door open in Clear Lake Shores, TX: setting up a smart opener

In Clear Lake Shores, 27.69% of the city's total area is water and the community sits surrounded by water on three sides, about a mile west of Galveston Bay. That kind of daily exposure to humid, salt-tinged marine air is the sort of condition that corrodes chain links and sprocket teeth faster than it would inland, and a chain that's rusted stiff can bind in the rail instead of simply jumping — the opener strains against it, and the door won't close.

What gets checked when a garage door chain won't close

A working chain has to sit at the right tension, ride true on the sprocket, and pull a trolley that's still square in the rail. Any one of those out of spec is enough to leave the door stuck open, so the chain, the sprocket, and the rail all get looked at together rather than assumed to be one single point of failure.

Add in that the eye of Hurricane Ike passed directly over the city in September 2008 and destroyed many homes here, and a chain-drive opener that took on water or storm debris that year can still be carrying corrosion damage that only shows up as a jumped or seized chain years later.
