✅Original New OEM Whirlpool 4389102 Refrigerator Ice Level Control Board

The Original New OEM Whirlpool 4389102 Refrigerator Ice Level Control Board is a specialized electronic component kit that manages the automatic operation of your refrigerator's ice maker. It is typically referred to as an Ice Maker Optic Control Board Kit or Emitter/Receiver Board Set. Key Features and Functionality: Feature Description Primary Function Ice Level Sensing and Regulation. It acts as the brain for the ice maker's "full" detection system. Two-Part System The kit consists of two separate boards that work together: (1) Emitter Board (sends the signal) and (1) Receiver Board (detects the signal). Infrared Technology It uses an infrared (IR) light beam to monitor the ice level in the ice storage bucket. Operation The Emitter board shines an IR beam across the top of the ice bin to the Receiver board. Ice Production Control - When the ice level is low, the beam is uninterrupted, signaling the ice maker to continue production. - When the ice bin is full, the ice blocks the beam, signaling the ice maker to stop production. Failure Symptom Fix Replacing this kit is the solution for common ice maker failures, including: • The ice maker stops producing ice entirely (due to a false "full" signal). • The ice maker overfills the bin and causes leaks (due to a failure to send the "full" signal). OEM Quality It is an Original Equipment Manufacturer (OEM) part, ensuring perfect fit, proper voltage, and factory-tested reliability. Compatibility It is widely compatible with many side-by-side and bottom-freezer refrigerators from Whirlpool and its affiliated brands (including Kenmore, Maytag, KitchenAid, and Jenn-Air).

• 1. Infrared Sensing Technology Unlike mechanical arms used in older models
• this board utilizes an infrared (IR) beam to detect ice levels. The Mechanism: The emitter board sends a light beam across the ice bin to the receiver board. The Trigger: When the ice level rises high enough to block this beam
• the control board signals the ice maker to stop production
• preventing overflow. 2. Diagnostic Status Light The board features an integrated LED indicator (usually on the receiver side) that provides real-time troubleshooting data: Steady Light: Indicates the boards are functioning correctly and the beam is unblocked. Blinking Patterns: Specific flash sequences can indicate a blocked beam
• a faulty board
• or a communication error between the two units. 3. Comprehensive Kit Design Because the emitter and receiver work as a paired circuit
• the 4389102 is sold as a complete kit.
