New OEM igniter isn't lighting gas.
Last week I found my ignitor completely burnt up and the ignition control board was burnt too. Replaced both with new OEM White Rodgers parts. Furnace starts normally. Blower comes on, ignitor gets red hot but I get no flame. I am able to get it to light if I hold a lighter next to the burner. It seems like the ignitor starts to cool off before the gas get released.

Welcome to the forums.
Some replacement boards have programming plugs or pins where the warm up period can be changed for the igniter. Check on that too.

Make sure your getting gas thru the burner as well. The hot surface igniter should be sufficient to light the fuel given that it's hot when the gas is present.

Ummm. Most ignitors should get white hot to light the gas.
I'd measure the AC voltage being turn on to the ignitor. That should be 120 VAC. A bad circuit board might make a poor connection and turn on a voltage that's too low to heat up the ignitor properly.
