More about this in Rosharon

A garage door chain won't close when the motor runs but the chain either skips over the sprocket, binds partway down the rail, or drives the trolley into a limit setting that stops the door short of the floor. It's rarely the chain itself that's worn out — usually something is stopping it from finishing the job it's already doing. The town-level guide to garage door technician Rosharon covers every common fault in one place.

Call (346) 220-4724 and a crew working the Rosharon area will find out which part of the drive is the problem.

Why a garage door chain won't close even though the motor is running

A chain-drive opener pulls the trolley along a fixed rail using a loop of chain wrapped around a sprocket at the motor end. If that chain has stretched, jumped a tooth, or gone slack, the trolley can lose its grip partway through the travel and stall the door before it seats on the floor. The motor keeps turning, the chain keeps moving, but the door just doesn't finish coming down — which looks like the opener quit even though the drive is technically still running.

That intermittent pattern usually points to a limit or force setting that's slightly off rather than a worn chain, since a chain bad enough to fail outright doesn't typically fix itself by trying again. It still needs to be checked, because a setting nudged too tight can be masking early wear that eventually stops the door for good.

What decides the fix on a Rosharon garage door chain that won't close

Rosharon's housing splits sharply by era: close to 77% of it went up after 2000, much of that in Lakes of Savannah and the other newer subdivisions, while about 20% dates back to 1940–1969 from the town's older rural stretch. Newer chain-drive openers in the post-2000 subdivisions are more likely to be dealing with a factory setting that needs adjusting, while openers on the older side of Rosharon are more likely carrying a chain and sprocket that have simply worn down over years of use.

Roughly four feet of floodwater sat across much of Rosharon during Hurricane Harvey in 2017 — a chain-drive opener that took on that water can have a corroded chain or rail even years later, which shows up as binding or skipping right before the door reaches the floor.
With nearly 77% of Rosharon's homes built since 2000, most chain-drive setups in town are recent builder-grade openers, so a chain that won't close on one of these is more often a setting or trolley issue than old, stretched-out chain.
The roughly 20% of Rosharon housing built between 1940 and 1969 represents the older side of town where a chain-drive opener has had decades to wear at the sprocket and rail, which is exactly where a chain jumping or sagging tends to start.
