possible bad control board

Unlike a lot of ovens, you can't unscrew the fan oven element from (at least some) we Dietrich ovens. Turn off electricity first!. Now open the oven and unscrew the cover from the back (4 screws). You can see the circular element. The 3 fixings can be seen but have to be unscrewed from the back. To do this, take out the oven from the cabinet (typically you undo a couple of screws near the top to do this) and pull it free. Then remove the rear metal casing. This requires a special screwdriver with a T10 head. You expose back of fan motor. The element is removed by disconnecting the two spare connectors, and unscrewing three nuts that are buried in insulation using a socket set. After removing nuts pull out element from the inside of the oven. Now you can replace the element by reversing the steps.
