Anyone know why my furnace all of a sudden failed to display on a 2018 Montana 3730? It is like the furnace is not there at all! A/C and Fan modes only on display. Worked good last night - all of a sudden - no furnace? Error code 1 displayed for an instant - now nothing. Rig is on a surge protector and all circuit breakers are good. Ideas?
