AEG MCC3881E-M Combi oven
Pn 947 640 703
When the fan oven is in use it stops a short while after reaching temperature and clock stops.
I have replaced one of the thermostat sensors and sadly it has not cleared the fault. I am tempted to replace the other but I am concerned it could be a control panel fault which is very expensive. any advice would be greatly appreciated, Oven just out of warranty.

To be honest on this its more then likely the main control board. As what happens a lot on these is the wiring block on there burns and gives bad connections that causes this kind of fault.

Pull the oven out and remove the top panel again.
Then look at the control board behind the panel and you will see the wiring block in the middle.
Remove this and inspect the block and i think you may find this has burnt.
If so then the control board and the wiring harness will need to be replaced.
This is something i have done a lot of on these microwaves as the wiring block gives a bad connection which causes it to burn in the block and cause this.

So check that first before replacing the other parts and see what you find.

Thankyou for your reply. I did have a good look at most of the components at he time and there was certainly nothing as obvious as what you have suggested. i must admit that the sensor wire I replaced was damaged and I thought that would fix it! However I will investigate further when I am able as the appliance is in another property!
