The 620424 thermocouple fit the N400/ N500 family, but it has been discontinued. Many N510s light with a spark electrode rather than a thermocouple, so the hole above your burner may be for the electrode. Send us a photo of the burner area and your serial number and we'll tell you what goes there. 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.
