A chain-drive opener pulls the door with a metal chain running along a rail on the ceiling. Chamberlain describes it as a heavy-duty, bicycle-like chain, and calls the type durable, dependable and budget-friendly. (source: Chamberlain) Garaga's opener guide adds that a chain unit remains a sturdy, budget-friendly pick for a detached garage. (source: Garaga)
Stand under the rail with the door closed. If you see a loop of chain links running to the motor and a clatter you can hear from the kitchen, it's a chain drive. Genie builds its chain rails in two forms, a 3-piece C-channel and a 5-piece tube style, so note which one you have when we talk parts. (source: Genie)
If noise is what bothers you, there are options short of replacement:
Replacing makes sense when the motor or gears are worn out, when you want features like battery backup or a camera, or when the garage sits under a bedroom and you'd rather switch to a belt drive.
Current chain models are not stripped-down units. LiftMaster's 4690L is a Premium chain drive with a DC motor, battery backup and a built-in camera. (source: LiftMaster) Genie's ChainMax 1000 runs on a 140V DC motor with opening speed up to 7.5 inches per second. (source: Genie) Chamberlain's chain models come with built-in Wi-Fi, battery backup and myQ options. (source: Chamberlain)
If you are moving from a 7 ft to an 8 ft door, Genie sells extender kits for 7 ft C-channel and tube-style chain rails. (source: Genie) Other brands handle rail length their own way, so we confirm the rail before ordering anything.
