If it sparks, lights for a few seconds, then goes out, the board isn't sensing the flame. The spark/sense electrode is a common cause. Clean it and the burner, check that the electrode tip sits in the flame with the right gap, and check its wire and ground. The Spark Sense Electrode 639198 for the N3141 has a 2-3 week lead time. Also check the LP pressure. See our not staying lit on gas article. The N3141 is discontinued, and Norcold's current 3-way model is the Norcold N4150. See our Norcold replacement guide.
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.
