York Furnace - Indicator Continuous Flash: Flame - No Call For Heat

Today the furnace stopped working. The indicator light is on a continuous flash, which according to the sticker on the furnace equates to "Flame - No Call For Heat"

So, what does that mean in laymans terms. I'm hoping it's a thermostat problem but would like to get some input here before I go buy one.

If the fan is set to on on the thermostat, the fan will run. When I power the furnace off and turn it back on, the blower starts, I don't see any ignitor glowing, don't get any flame. I can very briefly smell a little gas. Then it shuts down and the indicator light flashes continuous.

Thanks in advance for your information!

Sounds like the glow bar is bad or the electronic board is not putting the 120 volts to the glow bar. Your stat is ok . It is starting the inducer and you said you smell the gas which only goes for about 6 seconds.
You would have to check and see if you are getting the 120 volts going to the glow bar, 15 to 30 seconds after the inducer starts. paul

Paul. Not what I was hoping to hear but I genuinely appreciate the information and the lightning quick response. I'll call a tech out in the morning. Luckily we have zoned heating so we'll be ok with the 0 degree temps tonight. Again, thanks!

Rudy,


My interpretation is different.

Frankly, I find your description of what is happening too vague to be able to determine what is happening.


You talk about turning the fan on --- but exactly what does that mean? Are you turning the thermostat to the "fan on" position that manually turns on the fan that circulates air around the house? Or are you simply turning the thermostat up so that the inducer fan that circulates combustion gasses through the furnace turns on? Can't really tell.

To describe what is happening in a way that is helpful, you need to take the cover off the burner compartment. Turn the thermostat up to 80 degrees and describe in detail the sequence of events you observe happening at thew furnace.

The furnace doesn't just "turn on." A series of events has to take place and if the furnace isn't working that series will stop at a particular point which is a first clue as to where the problem may be.

SeatllePioneer - I can give a bit more detail now. The blower runs when I set it to "fan on" not because the thermostat is turned up.

When I turn the power off and then back on at the furnace, it does appear to run through a definite cycle. A fan is blowing, I hear clicking noises, I get a brief smell of gas. But as I said before, nothing glowing, or igniting. After about 5 min or less it turns off and the indicator light starts blinking continuously again.

Well, you haven't described the sequence of events that occur in detail. Unless you do that you can't expect to get help that is worth very much.


Sorry.

It was the ignitor. I paid $121 for the part and $75 for the service

I'm having the same problem. The small fan(not the blower) runs. The glow plug glows but does not ignite the burner. Not sure if gas valve is opening. How can I tell?. I don't think its the flame sensor. I've had that problem before. When that is bad the burner lights then shuts off. Any help would be great. Thank you
