AEG Competence?

My AEG Competence double oven switches it's self off, this happens to both the top and bottom ovens with no particular pattern. Sometimes after just a few seconds or it can stay on long enough to cook the christmas turkey!! anyone got any ideas?

check to see if the cooling fan is working.blows out of top oven door area on grill settings.if no air blown out suspect stats or cooling fan seized
