This disclosure is related to software that responds to consumer usage patterns in order to create more ice. The developed software monitors ice dispenses rather they are crushed or cubed. When a threshold of the number of dispenses within the preset time period has been met, the freezer enters a high demand mode. During high demand mode, the freezer is commanded to run at a colder temperature for a preset period of time. The method described in this disclosure includes setting a threshold for the number of dispenses within a time interval and detecting the number of dispenses that are related to a trigger's activation. The method continues with sending a signal when the number of dispenses surpasses the threshold within the time interval and taking a corrective action that increases the production of ice when the signal is received.
