Oven is 8 years old!
So just to reiterate, we replaced the PC board for the Selector switch which cured the flashing oven light and flashing display fault as advised by another technician on JUSTANSWER.
We then used the Oven after we replaced the board that night and it worked fine!
The next morning, the new fault appeared regarding the main Oven light itermitanly working but the oven will not heat up, the dispay clock appears to be working however you usually see a large arrow on the screen when the oven heats up but this is not happening either?
Is it pure coincidence then that the main operating board has now gone kaput, as im worried about oredering this part for £260 if this is not the problem!
we are not very happy with the Gaggenau engineer who originally came to our house to fix the flashing light display fault, he claimed it was moisture behing the dispaly and that it would eventually dry out, so hence why we have resorted to JUST ANSWER for help and replaced the defective parts ourselves!
So should I order the part today?
By the way, many thnaks for your speedy response!
