Rudd 90 plus furnace igniter won't glow

(Not sure of the exact titles of the objects I have mentioned in my description)
I have run the furnace through the cycle several times. Each time the blower starts to run for about 30 seconds. 2 green lights come on in the electric panel but the glow wafer never glows and blower stops. Can restart immiediately by pushing & holďing switch on filter access door opening. Is this just the glow wafer or could it be a gas release valve? Thanks.

Welcome to the forums.

You can check for 120vac to the igniter when it should be lit but more than likely it is cracked/damaged.

One screw (black arrow) holds it in place. The red arrow is pointing to the new igniter surface. Yours will be discolored and may be cracked. Be careful.... these ceramic igniters are as fragile as eggs. If you bump the surface..... it will shatter.
