Hi there,
It's that time of year in Chicago to fire up the furnace and lo and behold, mine is not blowing hot air. It turns on correctly from the thermostat, the draft motor fan starts spinning, the gas kicks on for a few seconds, it pumps cold air into the house for a minute or two, and it kicks off. What is missing is that the ignitor is not getting hot or glowing.
I've done some investigation on the ignitor. I checked it's resistance and it comes in at around 83 ohms. Between the ignitor and the control board there are two wires delivering power. I checked the voltage on those wires coming out from the board and I get a reading of zero volts throughout the whole cycle. So I take this to mean that the ignitor is ok, but it is not getting power. Does this mean I have to have my control board replaced? Seems like the only other thing could be the wires from the board to the ignitor but I checked continuity on those and it seems fine.
Here are the details on the furnace:
- Rheem Criterion, Model # RGDJ-12EARJR
- Control Board: 62-24268-01
Thanks for any and all help!
