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

Listen for the motor before assuming the chain is the whole problem. If the motor hums or runs but the door doesn't move, the chain has likely slipped off the sprocket or gone slack enough to skip. If the motor doesn't run at all, the chain was never going to matter — that points to the opener's wiring or logic board instead, and running the chain by hand won't tell you which one it is.

A stripped drive gear can look like a garage door chain won't close problem

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

The plastic drive gear inside the opener housing is usually the first part to wear out on an older unit, and once its teeth strip down, the chain has nothing left to catch even though it looks fine hanging on the rail. This is common enough on aging openers that a garage door chain won't close call often turns into a gear replacement rather than anything wrong with the chain itself. Some doors with this problem actually have garage door chain replacement Huffman repair instead.

What flooding adds to a garage door chain won't close call

The 128 homes documented as flooded in Huffman during Harvey, and the homes pulled from standing water in Lochshire and elsewhere during Imelda two years later, mean a real share of local openers took on water at the motor housing or the wiring that feeds it. A chain can look intact and still not close the door if the motor windings or the circuit board behind them corroded after either event — which is why a garage door chain won't close visit on a flood-exposed door usually includes pulling the housing cover, not just checking the chain.

What Huffman's two building eras mean for a garage door chain won't close call

Broken chain stops garage door from closing in Huffman, TX: the repair crew

With local housing concentrated in the 1970s and the 1990s, a lot of Huffman's chain-drive openers are old enough that the drive gear, chain tension spring and trolley carriage have simply worn past their service life, independent of any flood. Add in the settling that comes from Huffman's sandy Piney Woods soil eroding under a slab after repeated heavy rain, and a door that's slightly out of square can put extra drag on the chain and trolley even on a unit that's never seen standing water.

Don't keep running the opener when a garage door chain won't close

Holding the button down just spins the motor against a chain that isn't pulling the door, which is a fast way to burn out a motor that was otherwise fine. If the door won't close and the chain looks loose, off the sprocket, or the motor isn't turning at all, leave it alone until someone checks the gear, the trolley and the wiring together.
