Replaced the igniter
Remove the door and drawer. Your going to need to work under the oven so get a flashlight and look at the layout before you start removing stuff. Be careful with the parts some are sharp and so is the broiler spreader inside.
Unplug the unit or switch off the breaker. You would be surprised the damage you can do to controls by working live, even with low voltage.
1 Remove the Bottom plate (2 screws), be sure to re align the threaded clips this will make replaceing the plate when your done so much easier. Of course you could ignore them like I did the first time and have to take the plate back out and line them up.
2. Disconnect the high heat bug nuts underneath. They are stuffed into a little round hole at the back of the unit. Clip and re strip the ends, because you'll want to start fresh as this is a stranded wire.
3. I loosened the burner tube so I could get a spin tight on the clamp that holds the igniter to the tube. (1 screw in the front) (2 screws at the back 1 you remove from the top the other from the bottom) You should probably use a small wrench or socket set if you don't want to remove the tube. I was using a ten in one and didn't feel like heading out to the garage.
4. Replace the igniter
5. Secure the burner tub and thread the wire down the same way you removed it. (These tips were already stripped if I remember correctly)
6. Using the new supplied high heat nuts attach the new igniter and push the wires back into the hole. Make sure the burner tube is seated the way it was before.
7. Replace the bottom plate, the door and the draw.
8. Re power and pre heat the oven to 350 or so to get rid if that new metal smell.
