I can't confirm what E3 means on the N10DC from here. Even on shore power, the fridge runs off your RV's 12V system through the converter, so check the 12V at the fridge while the compressor runs and make sure the back vents aren't blocked. The control module 640178 is the most common part to fail.
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.
