Oven ignighter stays on

My oven ignighter stays on when plugged in
I have replaced the oven senser and the ceramic oven ignighter
Any hel would be appreciated

Hi.

Check if there is 120VAC at the ignitor disconnect plug.
Check if the wires from the ignitor to the control are not shorting to the frame.
If the wires are OK and you have 120VAC at the plug - replace the control board AP6009732
