So I believe I finally have it fixed, although it cost me another ~$300 for a new ignition board. On the old ignition board, I was starting to see CE error code and then it went away after a power cycle. I could get the heater running with the old board with more or less power cycle trial and...

Yeah, well trying to save money. Also an elec. eng.... Anyway, that didn't seem to solve the IF problem, I went out this morning for a test and still had the heater cycling destined for an IF code. I turned off the heater left for a few hours. I was continuing to look up flame sensing issues...

My heater worked flawlessly from 2009 to about 2021. I was battling first an IO code and then intermittent IF code and replaced both ignitor, fixed IO, and flame sensor with no change intermittent IF results. I suspected a heat exchanger leak due to some small about of water (not much) from...
