  • Page 13 1997 REFRIGERATORS GLOBAL NEW GENERATION DISPENSER In 1993, a completely new recess assembly in the freezer door was introduced in all side-by- side dispenser model refrigerators. These models have a single pad (rather than cradles) for dispensing water, crushed ice, or cubes. The selection of water, crushed ice, or cubes is made at the control console.

  • Page 14: Dispenser User Operation

    1997 REFRIGERATORS GLOBAL NEW GENERATION Dispenser User Operation On non-electronic models, water and ice selections are made by positioning the selector switch knob which is located at the lower left side of the console. The switch has a detent at each selection to ensure positive positioning.
  • Page 15 1997 REFRIGERATORS GLOBAL NEW GENERATION Dispenser User Operation - Electronic System A new control console was introduced on all 1993 models that had the electronic system. However, the electronic monitor and diagnostic feature was similar to previous models. 1. Touch pads provide for the selection of “chilled water”, “crushed ice”, or “cubed ice”. A beep will sound each time either pad is touched.
