If a new board didn't fix it, check whether the heat source is working. On gas, look for a flame. On electric, feel near the heater for warmth. If the heat is on but it won't cool, the cooling unit has failed. For the N8V, the replacement is the Nordic 6608, or you can go with the Norcold N8X. The N8V's optical board, the 639509, is discontinued.
