I found this helped my specific Whirlpool stove with DSI and I think it will probably apply to all. If you are having lock out problems, over heating, shut off or other symptoms that point to the three or four service pointers referring to the updated burner/ignitor assembly, or the additional ground on the dsi controller, and the UPGRADES HAVE BEEN DONE, but your oven is acting up again. Check for corrosion on the ignitor tip, it is used in the ground circuit for the flame sensor. If it has been corroded too much it will interfere with the flame sensor function in the circuit. A little emery cloth with remove enough corrosion to make the circuit reliable again. Just thought I would toss that out there.
