Hi all,
Just a follow up. I never thought to check the furnace operation, didn't think I'd even need it this summer, but the mountains of VA get cold in the morning.
Well, when i tried to fire up the furnace this morning off the same thermostat - nothing.
I am using the heat pump instead for now, but the furnace side doesn't work at all. So usually the fan kicks on then the furnace will fire a few seconds later but in this case it's completely dead.
So I'm wondering how it's possible when the ground wire was tapped off the outlet that affected operation of the furnace heat? It seems that the only thing that the thermostat will control now is the AC on the roof - either in heat pump mode or cooling.
Not sure if anyone has had a similar issue before, but i would think the deader putting on a new roof would have nothing to do with the furnace.
Any ideas?

Thanks everyone
