Why can't I light the oven?

Update: I suspected the ignitier coil was the issue since it was not glowing. I couldn't get a good look at it, so I used my cell phone to reach inside and take some pictures of it.One of the attached pictures shows the igniter in place, the other shows it removed. The apparent break in the coil told me that my suspicions were probably correct. I found an instructional video online that showed how to test it. It tested bad. I called a local appliance parts store and found an OEM replacement for $66.40 in stock. I also checked online and could have ordered it for under $25.00 but would have had to done without an oven for 2-3 days and I had taken off work early today to get this repair completed. Total repair time (including troubleshooting) was maybe 2 hours. Replacement was easy. 2 screws held the unit in place and they were easy to access. The electrical connection was made via two ceramic wire nuts and the new unit came with two new ones and the leads were plenty long to make the required connections. Total repair cost; $66.40. Total repair time; approx. 2 hours. Tools needed; 1/4 inch nut driver. Estimated dollar savings; $200.00. Safety Reminder: Disconnect electrical supply and shut off gas supply before begining repairs.
