I have a trane outdoor unit that my dogs have chewed the wires on. I just want to reconnect the wires but dont know which color goes to what. I have a green, white, and red wrapped in brown coming out of the box on the house. I have a blue and a yellow coming out of the Trane unit. Anyone know which colors connect?
most likely it's the red and white wire the green is probably not used,you can hook the wires red and white wires to the blue and yellow wires either way because its one circuit
this is true, however, not all installers follow any kind of code
the brown cable with 3 wires inside come from inside your home, through the wall, through the box, then to your outdoor AC unit
check at your furnace
this brown cable should be found entering the furnace
check to see which wires actually connect to the control board, just to be safe
