If the flame goes out as soon as you let go of the xxxx , it's usually the thermocouple, not a board. The N145 uses a thermocouple to hold the gas valve open. Hold the xxxx for a full 30-45 seconds after it lights, then clean and tighten the thermocouple connection at the gas valve. If it still drops out, the thermocouple is weak. The N145 Thermocouple 631753 and the Power Board 631562 have both been discontinued by Norcold, so check the product pages for any remaining stock. See our N145 parts page. Norcold doesn't list a direct propane replacement for the N145. The closest compact model is the Norcold DC740 (12V DC only). 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.
