ABSTRACT:
A control system for an icemaker and ice dispenser operates the icemaker to periodically harvest ice for introduction into a hopper of the ice dispenser whenever the hopper is less than full. During and in response to initiation of each harvest cycle, and independent of the level of ice in the hopper, the ice in the hopper is briefly agitated twice, once shortly after harvesting begins and again toward completion of the harvest cycle, such that the second agitation and the cycle end at about the same time. A thermostat senses the level of ice in the hopper, and when ice reaches the level of the thermostat, the icemaker is turned off.
