What Happens If The Secondary Heat Exchanger Of A Furnace Fails?
I have a Payne HE Gas Furnace (plus 90, I know about the lawsuit and settlement) and simply wonder what would happen if the secondary heat exchanger would fail? We are having a water leak from it, and I am wondering if it links to a failing secondary heat exchanger failure. Any answers?

Yes, a leak would be considered a “failure”. Leaks don’t tend to heal themselves, in fact they tend to go the other way. If there’s been a recall, you best get in on it.
Winter’s gettin’ real close.

Water leaking could be a few different things. I would first check all the hoses and make sure none of them are clogged.
