Wiring burning from old payne,100fau-14. Suspect limit switch not turning gas valve off but visual of heater exchanger shows streams of rust where water dripped in a small stream. Cannot see cracks but rust lines as above. Not alot of time on visual with cam. On Green Sheet someone was selling heat exchanger assume he welded patches. Cannot find ad again or my imagination.
