Usually not. A fuse that keeps blowing means something the board powers is shorted, often the DC heater, the igniter circuit or the wiring. Disconnect the loads and test the heaters with an ohmmeter before replacing the board. The Power Board 631562 has been discontinued by Norcold, so it's only available while our remaining stock lasts. See our N145 parts page. The closest compact model in Norcold's current lineup 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.
