The opener motor can be running fine and the door still won't move, because the chain is the only thing actually connected to it.

What it means when a garage door chain won't close the door

Inside a chain-drive opener, the motor turns a sprocket, the sprocket pulls a loop of chain down a rail, and the chain drags a trolley that's clipped to the door's overhead arm. Break any link in that chain of connections — literally or figuratively — and the motor can run all day without the door budging. A chain that's jumped its sprocket usually announces itself with grinding or clicking; a chain that's just gone slack over the years is quieter, and the door simply stops a few inches into its travel or won't start closing at all.

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

With Jacinto City's median house or condo built back in 1957, a lot of the openers doing this work today have been re-drive-shafted or replaced at least once, but the chain-and-rail setup on an older door frame doesn't always get swapped out at the same time. A rail that's slightly bowed or a bracket that's loosened over decades gives the chain more room to jump or bind than it would on a newer install, which is part of why this problem shows up more often on the town's older streets.
