Replaced oven igniter.
Shut off gas to oven and unplugged.
Removed oven racks then oven bottom (2 screws in back of oven inside). Removed warming drawer underneath oven, clips on rails one pushed down the other side pushed up. Removed 2 screws holding in burner bar back center from warming drawer compartment. Used a magnet so I didn't drop screws. Removed screw at front inside oven holding burner bar. Cut wires as close to old igniter as possible to give myself longest leads to attach to. Unscrewed igniter from bottom of burner bar. Attached new igniter to bar. Wire nutted to old leads and pushed back into oven warmer drawer compartment as I replaced burner bar. Reattached burner bar and then tested all parts of the oven before replacing oven inside bottom. Replaced oven inside bottom and has worked ever since.
