    Lennox GCS3-1353-350410Y - Wiring Diagram and Service Manual

    Does anyone has access to hopefully the wiring diagram for this OLD unit? Can't get the heat on and multiple issues with wiring but the diagram is long gone (worn off). Any help is appreciated.

    I can't help you with your diagram, but I can sympathize with your pain. Gotta love 150 white wires with all the ink lettering worn away.
