A discussion worth having, what causes intermittent flame failure? A few things: -Dirty burners -Defective gas valve (effecting gas distribution) -Flame sensor issues (dirty or poor ceramic insulation) -Poor burner ground -Defective HSI or sparker -Defective ignition board -Loose electrical connections Please add anything else that comes to mind. Or any experiences you've had with this.
