We have a white AEG Competence Oven that is turning itself off randomly. It turns itself off during cooking leaving just the power light on and clock going, but no cooking heating.
This can happen twice just after turning on and then not for some days. We have tried ever lower heat settings to no avail. Taking the cooker out reveals no burn marks on any wiring or circuit boards and all fans spin smoothly. Cooker is only 8 years old and has not been used heavily.

Any ideas?
What parts should we replace?
