The Thermistor 618548 is listed for the N6/N8/900/9000 models. I can't confirm it fits the 6163. It has been discontinued by Norcold and replaced by the in-stock Thermistor 636658/621742. The 6163 is discontinued, and Norcold's replacement is the Norcold N7X. See our Norcold replacement guide.
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. You can also browse www.rvfridgeguys.com.
