Pull the panel off (assuming bake) the bottom, detach the flame spreadder, take the couple screws holding the burner in out. Put a drop of oil on the threads on the back of the flange on the burner for the ignitor, unscrew ignitor, (if you got one with a plug unplug the old one, plug the new on in, if you have the CERAMIC wire nuts, cut the wires, strip and use the wirenuts) - all of this of course with the unit unplugged..... reverse process.....
