this is kinda hard to explain, but the controls are essentially a series of cables. There are also some clips that hold the cable sheath stationary so that when you move the dial the cable is free to move within that sheath. If the clips come off or break then the entire cable/sheath combo tries to move and the entire thing just doesn't work. Try pulling it out to have a look for yourself, might make some more sense.
I've also seen a couple where the plastic gear teeth behind the dials just break off.
Pull the whole thing out and inspect it, it's easy to find another at PnP if necessary.
