Exact Fit for W10757851 Optics Boards Kit 4389102
for All Models with vertical ice container in freezer door.
The ice maker is controlled by this ‘Optics Board Kit’ that scans the level of ice in the ice container. When the ice level in the container blocks the led beam (Full of Ice) it (shuts off the ice maker). When the ice level in the container is below the led beam (Low Ice) it (turns on the ice maker). If the ice level control board fails, the ice maker will stop making ice.
Be sure to correctly diagnose before purchasing. Here are the 4 things to check! (Freezer temp. approx. 0? to 5?) – (ice level optics board) – (water inlet valve) – (ice maker).
