Hey yall! So I've come across an issue with a clients minimax NT.
This heater will not ignite for no one. Currently I'm receiving 120v in and out of the hot surface ignitor, I can see it turning RED. The gas valve is receiving 24v at the blue and white wires. Incoming Gas pressure is 8" wc. When opened its at 4". Blower pulls and blows air well. But the control board gives me a E04 code. and the kicker is that the burners will NOT ignite. Orifices are clean, oxidation is minimal. Heck I even plugged 2 of the 8 burners to see if the increased pressure would at least light the burners. But again, no luck.
What am I missing?
