What has failed when the door opener motor runs but the sprocket is not turning?

I have a 1/2hp Craftsman garage door opener model #139.53625. Initially the door would move a few feet then stop, forward or reverse, motor continuing to run. Now, if sprocket is moved by hand by pulling on chain, motor will move chain a couple of inches, then sprocket stops, motor continues to run through normal cycle.
