A garage door chain won't close problem shows up when the motor runs, the sprocket turns, but the door either stalls partway down or the chain goes slack instead of pulling the trolley toward the door. The chain is doing the pulling on this style of opener, so any slack, a jumped sprocket tooth, or a trolley that's disconnected from the carriage will stop the door from finishing its trip down even while the unit sounds fine.

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

On a chain-drive opener, the motor turns a sprocket that pulls a chain looped around a rail, and the chain drags a trolley connected to the door. If the chain has stretched loose over time, or a link has jumped off the sprocket, the motor can spin without the door actually going anywhere, or the door will start down and then stop short. That's different from a sensor problem, where the door reverses back up — a slack or jumped chain usually just stalls.

A garage door chain that's gone slack usually needs tension, not a new chain

Most chains don't need replacing the first time this happens. The idler pulley at the far end of the rail has an adjustment point that takes slack out of the chain, and on a lot of calls that's the whole fix — as long as the sprocket teeth and the trolley connection are still in good shape underneath.

What a garage door chain won't close call in Tomball tends to run into

Tomball's median home was built in 2005, so a large share of the chain-drive openers still running in town are original to the house — two decades of heat cycling and use on the same chain and sprocket. Tomball's humid subtropical climate means hot, humid summers every year, and that kind of heat swings dries out chain lubricant faster than a milder climate would, which is part of why an older chain here tends to stretch and go slack rather than snap outright.

Broken chain stops garage door from closing in Tomball, TX: a service call at a Texas farmhouse

Garages near Spring, Willow, Mill and Walnut creeks took on rising water during Hurricane Harvey, and chain-drive hardware in those specific garages is the hardware most likely to have picked up rust on the rail or the sprocket since. A chain that's fighting corrosion on the rail will bind and lose tension faster than one that's just aged normally, even on the same-age opener.

A garage door chain won't close the same way at Willowcreek Ranch as it does on an older street

A garage door chain won't close problem looks different depending on which part of Tomball it's coming from. Willowcreek Ranch, the 750-acre gated community built around its own lake, is newer construction with recent opener installs, so a stalled chain there is more likely a sprocket or alignment issue than years of wear. Older streets closer to Tomball's historic core are more likely running an opener that's simply due, chain and all.
