F1 on a DACOR CPO230 -- SOLVED --
In my case the issues was two broken solders joints on each of the encoders (the electronic component on the printed circuit boards behind the two main oven selection knobs). Once you have access to the two main circuit boards (also referred to as key panel or touchpads), one for each oven, you can check whether or not the encoders move on the circuit board (wiggle them). If any wiggle is present then solder joints have weakened over time in particular the two outer ones at each end of the solder joint row. You might be able to see a hairline fracture on those solder joints
How to fix: first take care of the wiggle by gluing the four corners of the encoder on each side of the Printed circuit board. I use Marine Weld expoxy glue. After drying the encoders can no longer move on the printed circuit board. Second re-solder any joints that show sign of weakness (the two outer ones in my case).
Third: before re-assembly spay some deoxitD5 inside the encoders and let dry.https://photos.app.goo.gl/EdK3uVi8od4v5LEi8https://photos.app.goo.gl/LiSG29NyHzR8atMz7
Oven stops after a few seconds -- SOLVED --

came back promptly and worked.
Getting to the Printed circuit boards on a DACORCPO230.
- Pull all knobs straight out (a small twist helps on some). Remove the two screws that hold the glass panel in place and set glass panel aside.
- Remove the long metal frame at the bottom of the glass panel (top of the oven door, 5 screws)
- Remove 4 screws (2 on each side) of the metal panel holding the timer and printed circuit boards
- Tilt panel forward and remove all wire connectors until the panel can be removed (take pictures to note where all connectors go)
- With a small screw driver pry the metal washers that hold the axis of the two main encoders. One small tab at a time and the washers come off
- Push back on the black plastic lock tabs, one by one, to release the printed circuit boards from the front panel.
