1995 Coleman DGAT056BDD. Old booster motor ran but I was getting a centrifugal switch (two flash) code. Replaced booster/centrifugal unit and got rid of the two flash code but still don't have a furnace because of the one flash ignition failure code. Now what? Flow chart seems to point to the ignitor. I can hear the centrifugal click, ignitor doesn't glow as it should, I hear the gas valve open and close. Seems odd that two things would fail simultaneously.. Help! It's cold out

If everything is "clicking" correctly and igniter is not glowing, replace igniter. I would test for power to the igniter first with a multitester. You should get 120v to the igniter terminals/plug at some point during the start up process. If you have power then igniter is bad.
