Abstract: An ice maker for use in a refrigeration apparatus as well as a method of optimizing ice production in an ice maker. The ice maker has a mold and a fan selectively operable to direct moving cold air past the mold during the ice formation process. In the preferred embodiment, the fan does not operate during the harvest portion of the cycle. A fan assembly consisting of a fan or blower, a motor, a switch in series with the motor and leads for electrically interconnecting the motor and in switch with the icemaker power supply is preferably assembled as a module removably interconnectable with the icemaker as an optional feature. The icemaker has an increased the rate of ice production due to the increased rate of convective heat transfer.
