Abstract
An ice maker is provided that may include cooperating primary and secondary coils arranged on opposite sides of a freezer cabinet wall for wirelessly transmitting electrical power through the freezer cabinet wall to energize various ice maker components. During the wireless electrical power transmission, a data/control signal may be superimposed on the electrical power waveform to allow wireless transmission of the control signal, which can be processed by a logic circuitry for implementing component control methodologies.
