Used Round Style Oven Igniter WB2X9154 to replace the existing part for the second time in 25 years of use. Found the video on the AppliancePartsPros.com web site a little generic but very useful. Key takeaways include: If you don't have a 1/4 " driver it is worth the trip to a hardware store to buy one. All but the first 2 screws are 1/4"; use gloves. I did and still managed to cut my hand; use a drop light or a bright flashlight as much of the work is done under the oven box; a kitchen mat is helpful because you will be laying on your side to reach the electronics under the oven box; remove the component that the igniter is attached to, then cut minimal lengths off of the stove wire ends and have a wire stripper tool available to strip the ends to the same length as the igniter wire ends. When using the new ceramic wire connectors do not twist the wire ends prior to insertion into the connectors. Either wire from the new igniter can be used with either stove wire end. Test the connections by pulling gently on the wires to ensure that they won't come loose from the connectors; take smart phone pictures as you disassemble the various metal components and wiring. I had to refer to them to minimize reassembly time; be careful not to inadvertently turn the range knobs while moving the unit or getting up. I did and managed to fill the kitchen with gas before I noticed the gas smell. Good luck.
