ABSTRACT:
An automatic ice cream maker add-on accessory for use in the freezer compartment of a domestic refrigerator including a rear freezing air intake with a fan induced forward split flow path. A dual state thermostat provides cycling sequencing and hold control by means of first bimetal contacts to control cycling of the unit from a combined dasher and fan operation to a fan only operation by means of a voltage drop resistor to change the voltage on the motor when a predetermined mix temperature is reached under load. A second bimetal contact member, also sensitive to the temperature of the ice cream, provides a long term feature on the completion of the mixing operation.
