An icemaker of the type that dispenses ice through an opening in the front of a domestic refrigerator-freezer produces precisely formed crystal clear ice cubes and gently dispenses them one-at-a-time at a totally predictable rate. The ice cubes are formed in separate molds where they cannot touch each other or get stuck together. As each cube is pushed out of its mold, it slides directly into the dispensing chute. Thus, the ice cubes do not rattle around in a noisy plastic bin and there is no need for a whirling rotary hammer to smash the ice apart. As the ice gradually freezes, a miniature conveyor system moves the molds from where they get filled with water to where they get dispensed as ice. During operation, the system is barely audible.
