Customer:

should i see the ignitor in the little window where i see the red flashing code light?

Customer:

because all i see is the red flashing light, no orange glow

airheatman :

NO

Customer:

so where do i find it?

airheatman :

It will be in the burner area. You will have to remove panel

Customer:

ok

airheatman :

With panel off, you will have to hold or tape the door button switch in to allow furnace to get power

Customer:

ok

Customer:

i removed the small panel at the top of the heater, there is another little observation glass in it, i see the burners in there, but there is nothing orange, i can't locate the ignitor

airheatman :

Gas valves do malfunction, but are rarely the issue. The code is just saying that if failed to light.The first thing to check is inducer coming on.You have done that.Next is to see if pressure switch clsoes and sends signal to ignitor.If so, the ignitor itself may be the culprit and need to be replaced. If not sending signal to ignito it could be a pressure switch not closing.This can be a bad pressure switch,blocked drain,blocked intake or exhaust vent.It will be necessary to locate the ignitor and see if it tries to light or if it is getting voltage.To check for voltage will will require a meter.

airheatman :

Often a broken ignitor will be the issue

Customer:

I see the gas ignitor back in there, looks hard to get to, how would i replace that?

airheatman :

It can be difficult, might have to remove some panels, but is necessary to troubleshoot.If it was easy, no one would call us technicians .(lol).Seriously, you can follow the wires going to ignitor and remove wht you have to to get to it

Customer:

no voltage meter, but i think i see how to get to the ignitor now. I will get a replacement ignitor, turn all the gas off and electricity, and replace it. Thanks, XXXXX XXXXX i'm okay now
