Found this cracked Heat Exchanger on 17 yr. old Lennox gas furnace using the flame of a match. Turn the Heat to "off" & set Fan to "on". Then use a telescoping tool to hold a lit match in each chamber of the furnace and watch for any flame movement. If the heat exchanger is breached the flame will move around and flicker. This is very obvious in the right-hand chamber of this furnace. I will include a link to a picture of the actual crack in the heat exchanger that was taken after it was replaced. And there were no CO readings coming off of this furnace whatsoever! Read 0ppm on the Bacharach. Thanks for watching 👍
