Sorry, the 617998 control assembly for the 3163 has been discontinued by Norcold and we're out of stock. It's hard to find new now, so an RV salvage yard may be your best bet for a used one. We don't have a substitute we can confirm fits. You can see what's still available on our 3163 parts page. 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.
