You're probably right. If it works on 110V but not at all on DC (including the light), the DC power supply is the most likely cause. First confirm a solid 12V+ at the fridge's DC input and check the DC fuse. The DC Power Supply Board 163011200 for the DE/DC0041 is showing in stock now. The DE0041 itself is discontinued. Norcold's replacement was the N2090, and the Norcold NV1090 has now replaced it. 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.
