You shouldn't need a whole new valve assembly. The replacement burner uses an adapter fitting, and a matching brass adapter from a hardware or RV store usually solves the thread mismatch. The 621446 valve assembly is discontinued anyway, and I can't confirm the exact fitting you need from here.
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.
