I have a Plus 90, 398AAW. The furnace was working up until yesterday and then stopped producing heat. The inducer motor comes on and stays on. The blower motor does not come on unless I put the fan setting to ON. While on Auto, the blower doesn't come on. I don't see any pilot light or any clicking sounds. When I go outside and smell the air coming out of inducer air output (not sure what the right name is for that) there is the smell of gas in the air.
So, to me it seems like there is a problem with the electronic ignition, but I would love some feedback if anyone has some advice. I could also use some help identifying and locating what exactly needs to be cleaned, checked, or replaced.
Below is a picture of what is going into my heat exchanger:
1) I'm not sure what this thing is
2) I'm guessing that the red wire is the actual electronic ignitor, what's interesting is that it goes right up into the heat exchanger, there is not way for me to get to it without removing the cover for the heat exchanger and getting inside of it. Below is a closeup of this. Seems kind of scary to open something like that up but I'll do it if that's what it's going to take.
3) This thing is labeled as the "Spark Ignitor", my guess is this is a capacitor that stores power to actual send to the ignitor when it triggers.
I'm not really sure if I should be replacing whats at the end of the red wire going into the heat exchanger or if I should be replacing the black box labeled Electronic Ignitor, or both. I would love any help anyone can provide, it's getting cold in here.
