Get to the ignitor:
Open oven, clean out the crude, and remove the bottom pan to get to the gas parts.
Remove the nut to get the flame sheild off.
Remove screws that hold the ignitor.
I stripped one and had to pry it off with a strait slot screw driver while turning it with a phillips.
Unplugging the ignitor:
Pull out the drawer. Removed the 2 panels under the stove to access the ignitor plug.
Replace the ignitor and reverse the procedure.
I did remove about 20 screws and the main pan at the bottom of the inside of the oven, but it didn't help me do anything, so don't make the mistake that i made with that.
