That small extension on the N145 is usually a thermocouple interrupter or extension that ties into a safety or shutoff circuit. It doesn't normally wear out the way the thermocouple does, so most of the time you only replace the thermocouple and thread it back into the extension. If the flame won't stay lit with the new thermocouple, then check the extension. Heads-up: the 631753 thermocouple is now discontinued, so call 800-712-8822 or email info@rvfridgeguys.com and we'll help you find another option.
