Unfortunately, the 617983 thermocouple for the 3163 has been discontinued, and we haven't confirmed a substitute that fits the 3163's valve correctly. 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.
