The 640338 and 640089 have both been superseded by the 641592/ 51023, which is the current optical board for the N8DC and N10DC and is in stock. Since I can't confirm this 100% from here, please email us at info@rvfridgeguys.com or call 800-712-8822 with your model and serial number and we'll double-check it for you.
