-40 Windchill And Furnace Has Quit!


New problem this winter - not the flame sensor this time! No furnace at all and house cold so gas off, power off, back on again and blower came on but no flames at all. I think it might be the gas igniter so we are going out to get one right now, but here's the kicker. The blower won't come on at all now. The thermostat is set to a high enough temperature but I can't get it to kick in. Is it because it sense the igniter is toast? If I press the switch inside the furnace for the blower it does come on (but of course goes out again when I let go of the switch).

So - do we have a bigger issue here? It's really cold in the house - the kids are staying in bed to stay warm. Any help you can offer would be appreciated. Thank you!

My apologies - I should have done that in the initial post. It's a Carrier furnace and so far as we know it's about five years old - the people who owned the house previously said it was about a year old when we moved in.

Carrier Model 58CTA110 --- 10112
Serial Number 3903A27467
Series 100
September 2003


Thank you again. Sherri

You had power go out and back on? First: the blower comes on for 90 seconds and does a self check. After 90 seconds the inducer should start blowing and then the igniter should glow and burners should fire.

If that does not happen then take off the blower chamber and you will find a circuit board. Look for a automotive style fuse. It will have either a 3 or 5 amp fuse. Pull it off the board and see if it's burned out.

I think the blower switch you are talking about is the blower door interlock switch. This switch is designed to shut the furnace power off when the blower compartment door is removed. Otherwise not enough info for a diagnosis.

It was, indeed, the igniter. We didn't know any better and when we took it out it disintegrated (apparently touching it with bare skin is not a good thing). Anyway, it's Sunday and we couldn't get the part to install it ourselves so had to call a heating company. Almost $400 ... but it's warm and that's what really matters.

Thanks for your assistance.
