Help with KitchenAid KGST307 Igniter

I have a KitchenAid KGST307FBL0 that is a little over 10 years old. The burners and the broiler works. The bake funtion does not work. I’ve removed the bottom oven pan and the bake flame shield to get a better look at the oven igniter to see what it is doing. When I turn on the oven bake function, the oven igniter on the bottom does come on and glows bright orange but the bake burner does not get ignited. If the oven igniter is glowing bright orange could it still be bad or should I be looking elsewhere (like the valve & regulator assembly)?
If it is the oven igniter, what would be the correct part to replace it and what is the proper way to replace it? Thanks.

Most likely you need to replace the igniter ( Jenn-Air Gas Oven not Heating Properly because it is not reaching the proper temperature and thus the proper current draw to turn on the gas. I wrote about this on my blog post [URL="http://www.technicianbrian.com/2008/12/jenn-air-gas-oven-not-heating-properly.html) which covers how these igniter’s work. And if you have gone into the oven as far as you already have, then replacing the part will be easy to do. Unplug the old one, remove the mounting screws and put the new one on.

I have the same model stove and it has a few issues.

First off, when I try to turn on the top burners, none of the ignitors would ignite at all. It is as if there is no current going to the spark module.

Second off, I get a F5:E3 error and none of the buttons on the control panel response at all. I know it is not the board because I installed a new working board and the new board experience the same error codes.

Please help.

Thank you.
