Hello. My name is XXXXX XXXXX do my best to answer your question.Remember, you are not charged and I am not paid until you accept my answer.
I don,t have manual in front of me, is the error code 34.
IGNITION PROVING FAILURE
OK let me see if I can find a manual on your exxact furnace ,This is a common code on Bryant/Payne units
Just means the furnace attempted like 3 times and diodnt light
When you turn to heat what will hapen
nothing, fan will blow but no heat
There is a small vent fan called an inducor motor.Does it come on?
hmmm.......let me see if i can locate
similar to this
that does come on
and is still on but the error code is 34
Turn power off to furnace and then back on, Then go to heat. The inducer fan will start , after afew seconds the ignitor should start to glow bright orange,
should i see the ignitor in the little window where i see the red flashing code light?
because all i see is the red flashing light, no orange glow
so where do i find it?
It will be in the burner area. You will have to remove panel
With panel off, you will have to hold or tape the door button switch in to allow furnace to get power
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
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.
Often a broken ignitor will be the issue
I see the gas ignitor back in there, looks hard to get to, how would i replace that?
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
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
