How Is the LED Ice Control Wired on a Kenmore 1062198597 Ice Maker?

Kenmore Evolution

• The LED ice control on a Kenmore 1062198597 represents an evolution of the ice level sensing mechanism used in most previous refrigerator models. Instead of a mechanical (bail arm) contact method, the sensing of the ice level on the 1062198597 is accomplished via an electronics control that both controls power to the ice maker and performs system diagnostics with a convenient, easy-to-read LED readout. The system diagnostics for the Kenmore include both component and optics diagnostics.

Ice Control Component Location

• The Kenmore ice maker's electronic control is comprised of two printed circuit boards located directly on the inside of the freezer door. Each is mounted on opposing sides of the freezer liner. The emitter board is on the hinge-side of the Kenmore's freezer door cabinet, while the receiver board is on the opposing or "mullion" side.

Operation

• The Kenmore ice maker's thermostat automatically closes whenever ice has been produced and is ready for harvesting. When this occurs, the LED ice control's emitter board emits an infrared pulse to the receiver board, which in turn senses the pulse and starts a relay that provides power to the ice maker.

Wiring

• The ice maker's heater, water valve and motor are controlled by the emitter/receiver board circuit module combination, and the relay is sent along a wire to these components. The provided power from the relay allows for the ice harvest to begin. An ejector piece along the relay senses when the pulse is no longer active and de-energizes the relay. This de-energizing causes power to the ice maker to cease, bringing an end to the ice harvesting.
