Removed oven door, racks, interior bottom cover and burner shield. Igniter held in place with two screws (#8 sheet metal screws in my case, not the #8 machine screws sold for this purpose). Pulled oven away from wall and removed cover on lower back to disconnect igniter wiring. Removed old igniter pulling wiring through from back. Pushed new igniter wiring through to back and reconnected igniter. Replaced rear panel, remounted igniter using one old screw from original installation and one #10 self-tapping screw (one screw and hole damaged on removal). Tested, then replaced burner shield, interior bottom cover, oven door and racks, and pushed oven back into place.
