Unfortunately, the 621955 burner for the N51X has been discontinued, and the 621957 is sized for the N6XX/ N8XX and larger models, so it isn't a substitute. A careful cleaning of your existing burner and flue often gets it working again, but don't poke anything through the orifice. 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.
