If it doesn't show "on" when you push the lever, it's probably the switch. Confirm the switch with an ohmmeter. Can you hear the switch click when you push the lever? I only see it available as the entire chute assembly, 13005704W. If you want to save some money, just replace the switch, 28QBP0495 if it has 3/16" terminals, 28QBP0496 if it has 1/4" terminals.
