Can someone please verify my wiring? Coming from a Trane. The heat won’t turn on but the AC does.
I connected
Green to G
Yellow to Y1
White to O/B
Blue to B
Red to RC
Removed jumper.
Welcome to the user-to-user forum, @jwroberts7777!
It would be useful to see the other end of those wires at the furnace to make sure they used the right colors.
Maybe @speadie can verify then.
