Abstract
A control for controlling the time at which ice is harvested from an ice maker as a function of the temperature conditions within a below-freezing compartment in which the ice maker is located. The control includes sensing means for sensing the temperature within the compartment, first calculating means for calculating at preselected time intervals a time-related number based on a first temperature-dependent function when the temperature sensed by the sensing means is above a predetermined temperature, and second calculating means for calculating at the preselected time intervals a time-related number based on a second temperature-dependent function when the temperature sensed by the sensing means is at or below the predetermined temperature. The control further includes means for accumulating temperature-dependent time increments based on said calculated numbers and comparing the accumulated sum to a predetermined amount to determine whether an ice harvesting operation should be initiated. The apparatus further includes structure for effecting ice harvesting when the predetermined amount of temperature-dependent time increments has been accumulated.
