We have a De Dietrich DOD 788X pyrolytic double oven. The main oven stopped heating a couple of weeks ago in Circulating heat mode (element at back of the oven heats in this mode) and on removing the element at the back we found that it had literally melted and bits of it were scattered on the bottom of the oven. We replaced the element and the oven worked for about a week and then stopped working (fan works but no heat). We thought it was probably a bad element and replaced it but again no heat. We swapped the temperature probe between the top and bottom oven to see if that was the cause but still no joy. We can get the elements on the top and bottom of the main over to work (using the combined heat mode), but the element at the back won’t work (circulating heat mode). The fan seems to be working OK in the main oven
The oven is 10 years old, is it worth repairing and what else could be causing the problem, a relay switch on the circuit board?
could easily be a relay on the power board or a blown track
lift the board and look for damage on the print side first
i would trace the wire from the element and see where it connects on the board to give you an idea where to lookDave
depends who is doing it
if its you and you can figure it out then may not be a lot
if its an engineer cost depends on their ability to repair or replace board

Thanks, do you know where I can buy a board?
Given the age of the oven it is probably not worth repairing, sounds like this could cost > £300

you would ned to decide which card and make sure its correct for your model
price is not too bad but you would have to be certain thats your fault although its very likely but cant be 100{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} without checking
its possible the board relay has gone and if you can find it and solder a new one in its likely it could be fixed for about £10. Its also possible a track has blown on the board. if this is the case it can be cured in some cases by soldering some 30A fuse wire across the break
