I purchased the oven burner ignition and installed it. It took me nearly 30 minutes because the space I had to work in is very small. I was also in the middle of a bidding war on eBay at the time. I watched the video available on appliancepartspros.com twice. I was amazed that I only needed three tools: phillips screwdriver, flat head screwdriver and a pair of pliers.
First, I disconnected the oven from the electricity. Then, I removed the oven door. It makes accessing the part much easier. Removing the door required no tools at all. Then, I used the phillips screwdriver to remove the heat shield. I removed two screws which held the ignition in place. Then I went to the back of the oven and removed three screws to remove the rear cover. I later realized that I probably should have also removed the lower rear cover as well to make access to one of the wire connectors easier. But, I was in a bit of a rush and the space was tight so I didn't want to bother with that. I found both wire connectors and separated them and from the front of the oven, pulled out the ignitor. I needed the pliers to pull apart the wire connectors because they seemed fused together, not allowing me to pry them off with the screwdriver as shown in the video.
Installation took slightly longer because I couldn't fish the wires through the hole in the back. There was too much insulation that I couldn't even see the exit hole and each time I pushed the wires through, they would get stuck. As a solution, I cut a wire hanger and then twisted it around the wires of the ignition. I was then able to put it through the hole in the back of the oven very easily. I connected the wires in the back, using the pliers again to reach one of the wires (which I mentioned before, would have been easier to reach if I had also removed the lower back cover from the oven chassis). Once everything was connected, I put all the screws back in place, attached the heat shield and tested it. The oven turned on like a charm! Then I replaced the back cover, and went back to my eBay.
