Still scratching my head on this one. Everything appears to be working fine on my furnace, except that the ignitor is not getting juice to glow orange/white, hence the gas is not igniting? I disconnected the ignitor harness from the control board, ran the test sequence again, and determined that I wasn't getting 120 volts (no voltage) across the two leads on the control board during the 17 second warmup period. I actually tested for voltage during the entire test procedure, because I'm not sure as to what step the 17 second warmup process occurs. The trouble shooting guide appears to be saying that I need to change the control board. I'm not convinced of this step, yet. Is there anything else I can do, like test a relay (don't know where it would be and how?). I guess I'm trying to figure out why I'm not seeing 120 volts across the two leads. Getting cold now...

I've got a diagram of the control board from the manual; it's not bad, but it doesn't label all the components of the control board. Anyone know where I can get a detailed diagram? Any other suggestions to diagnose the problem further?
