I have a very long thread on here with all of the issues I’ve had over the last few months, but thought I’d repost with a more direct question for those not inclined to wade through 6 months of history.
I have two American Standard 80% eff furnaces bolted together that run in tandem to heat a 5500 sq ft poorly insulated house (AUC1D120A9601AD).
Yesterday morning I found one unit with no flame while the other was running. The igniter cycled and the furnace lit - but the flame was dancing wildly then went out. I did not check the error code on the control board before powering both units down.
I removed a burner - photo attached - but don’t have the experience to know whether the burners could be the issue.
From what I’m reading on the forum it sounds like it could be a cracked heat exchanger - ? Anything else (preferably less expensive and replaceable) that it could be?
