AEG B4101 – 5-M Oven turns off completely – works again after 20 mins rest

Hi,

I have a AEG B4101 – 5-M built in oven, a couple of times in the past week I have found upon returning to the oven that it has switched off while cooking something, nothing then works including the light apart from the clock,

I have also found that after leaving it for around 20 minutes to cool down, I can then turn the oven back on and use again with no problems.

I was stood near the oven yesterday while it was on and heard a strange sound like a fan slowing down when I looked the oven was off, so it seems to be a regular occurrence now, 20 mins later it worked ok again.

Does anybody know if this is a easy fix (I do have some experience working in electronics etc) or will I need to call out AEG?

Any help would be much appreciated, Thank-you.
