On the N811, 6 flashes means the high-temperature limit (thermal fuse) circuit is open. Since you've already replaced the board, eyebrow board, thermistor and cooling unit, check the thermal fuse/limit switch itself and its wiring. It may have been damaged or not reconnected during the cooling unit swap. Check continuity through that circuit. The Thermal/Limit Switch 2M0802 has been discontinued by Norcold, but we may still have limited stock. See our 6 flashes article and lockout/reset article. The N811 is discontinued, and Norcold's replacement is the Norcold N8X. 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.
