No, the 621957 is sized for the N6/ N8 and larger models, and the orifice is wrong for the N300. The 621953 for the N300 has been discontinued. A careful cleaning of your existing burner 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.
