There's no reset for that. If the thermistor checks good but the AC heater won't shut off, the relay on the rear power board is most likely stuck closed. On an N811 with a serial below 9056491, that's the 621991001 power board kit. Above that, it's the 628661 power board. Both are in stock. The N611V/N811V optical boards are discontinued, so if the front board ends up being the cause, the Norcold N8X is the replacement fridge.
