SOURCE: ignition failure code on
Sounding like a flame proving device is failing to sense flame. Try to clean the device with some steel wool. It is located right next to the last burner looks like a thick wire. Take the steel wool and gently rub the carbon that has built up off. Should only take 4 or 5 strokes. Let me know it that did it. Ken

if the unit has a flame (gas valve opening)the problem may be the fan going bad or fan relay -- sounds like unit going off on high limit control

Definitely a furnace issue. The gas valve is not opening if you see no flame. I have seen the igniter glow but not send enough voltage to the circuit board to make the gas valve open. If this is the case you should replace the igniter. It is very fragile so please use care when replacing. Check all connections at the circuit board as well as the gas valve. Check your gas supply. Check to see if you get 24 volts AC to the gas valve. If no, replace the circuit board. If yes, replace the gas valve once you confirm that you have gas to it. If you get a pilot flame only, you will need to clean the burners and flame tray that spreads the flame from one burner to the next.

You don't say if the blower is coming on, no blower would cause the limit to open. By the way, the limit is internal and auto-reset, not the manual reset roll out switches on the burner assembly.

Hopefully someone with more experience will respond as well, but my experience with this type of furnace is that this is likely to be a clogged line or gas feeder control device. The behavior indicates that there not enough gas being presented to the unit. Unfortunately this is NOT a DIY type of repair. A licensed plumber should examine this unit. Gas units can be dangerous if not serviced properly. Please seek local assistance frmo a professional.
