That's likely right, but it depends on your model. On the N6XX/ N8XX models, units with a serial number below 9185698 used the older 621334 gas valve, and the newer 637540 is for later units. Unfortunately, Norcold has discontinued both of them. If you send us your full model number, we'll double-check it and see if there are any options. You can see the other valves on our Norcold gas valves 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.
