I have a Trane XR90 gas furnace that has the improper pressure switch installed. I have the correct switch ready to install, but need to know to which terminals the red & yellow wires connect.
I've included a photo of the correct pressure switch...which is part number SWT02968. It has two vacuum ports and two spades.
There is no repair manual to which I can refer, so perhaps someone could advise me as to where the 2 wire connections are placed on this particular pressure switch.
Thanks and any help is greatly appreciated!
