I have tested the HSI. Power at the control board.
I took a part the burner box, (quite cramped) and was able remove the slanted metal to get a better look at the HSI.
(Hot Surface Igniter) and the Sensor.
There was a small crack upon very close look. So, I went and bought a new one and cleaned my sensor too.
(I had a back up limit switch, so I replaced that as well)
Now, when I was doing this, I almost removed both burners.
(there are two each that run inside of exchangers).
I did move them a little, but they are secure now.
I reconnected everything, it is starts just like it is supposed to.
The inducer goes on, first one click at the board, then I can see the ignitor light up and the burners light. Then, after a bit, the blower comes on and there is heat.
I am a little worried now. I see blue flames with some orange.
(not yellow). The flames have a clear connect at the burner and is seems to be evenly lit in pattern at burners, but there is some orange mixed in with the blue as look up the flames. If I remember right, (and I am trying) This should not be the case.
Any help with this? I am also sorry I was not clear at first.
I am trying to remember everything I am supposed tell you, but it's been a little hairy.
I have turned off the furnace for now. I am thinking it might some type of dust, but I wanted another opinion.
