Replaced both the igniter and temperature sensor. I did both just to play it safe even though the igniter was the most probable cause. The videos were very helpful, but my particular GE model made it very difficult. First for the temperature sensor. The plug was in the back where the video said it would be, but the sensor itself was screwed on inside the oven, not from the outside. That made it very difficult to pass the wire through to hook it back up. My trick was to tie a wire tie around the plug and pass the wire tie through the hole. The igniter was way worse. It mounts just like the video says, and discovered that there wasn't enough clearance to pull the plug up into the oven. The problem? The access panel to get to the plug is on the bottom of the oven. After getting the oven turned over, the rest of the repair was straight forward.
