The N604.3 is an older model with a mechanical thermostat (the one with the capillary tube), and we don't have one listed for it. The 636495 thermostat is made for the N300/ N305/ N306/ N260/ 322/ 323, so I can't confirm it works on your N604.3. 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.
