Good question. As my coach has a unified HVAC control system where the thermostat for my rearmost AC also controls my furnace and if the control board in that AC unit is inop, so to may be my furnace.
At this time, the control board of this AC unit is in fact inop and the wiring in the electrical box contains the board is smoked. As such, the thermostat for that AC unit will no longer operate my furnace.
I expect the AC unit to be replaced this coming week but I’ll feel happier with the ability to control the furnace on its own thermostat.
