Abstract

See full text

A knob assembly for an appliance includes a knob, a bezel, and restrictor block. The restrictor block removably couples within the knob. The restrictor block includes a first mating face that is configured to position adjacent the bezel on the appliance, and a second mating face is configured to position adjacent an inside surface of the knob. The restrictor block also includes a first pin positioned on the first mating face that is configured to restrict rotation of the restrictor block relative to the bezel, as well as a notch in a circumferential portion of the restrictor block. The notch is configured to restrict rotation of the knob relative to the bezel. While the restrictor block is installed within the knob, the knob is rotationally restricted.
