No heat...Rheem Criterion II

[paul52446m]

I have a Rheem Criterion II furnace that won't turn on. The draft inducer motor runs continuously but the hot surface gas igniter does not glow to ignite the burners. Any ideas on what the problem might be?

After the inducer starts the next thing that has to make is the pressure switch, after that the glow bar lites up. Test the pressure switch, if that makes unplug the glow bar and see if you get 120 volts going to the glow bar, if you do then you have a bad glow bar. Paul

any switch in-line with the igniter can be at fault. check the roll-out switches and door interlock.
