If your selector switch has a DC position, you have the 3-way version, and the 630808 DC heater fits all N305.3 models. That heater is discontinued now, though. Email info@rvfridgeguys.com or call 800-712-8822 with your serial number and we'll check the options. If your fridge is a 2-way model, it has no place for a DC heater, so you can't add one.
If you have any questions, just reach out at info@rvfridgeguys.com or call us at 800-712-8822. You can find everything we carry at www.rvfridgeguys.com.
