Replaced ignitor. Involves removing oven door, all racks, bottom pan, and bottom heat shield (1/4" nut driver). Then, pull range away from wall and remove back access panel (1/4" nut driver). Remove old ignitor (1/4" nut driver). Feed wires from new ignitor through back wall of oven and connect. Screw in new ignitor and test. Reinstall heat shield, bottom pan, door, and access panel. Spent about half the time cleaning grease and dust bunnies off the floor.
