I seem to have got the same problem with an AEG B2190-1. Similar sorts of cutoff problems and then switching back on after cooling. All started this weekend whilst in the middle of sunday lunch with guests. Not what you need!
Anyhow – thanks for these posts to help identify what does not seem to be a major fault. I would just like to check for sure that I have the same problem. I have taken the top off my oven and found a burned bulb-like object attatched to 4 wires (2 white, 2 blue) with spade clips (I think these are what they are). I have included a link to a photo. Could someone tell me if this is the THERMAL CUT-OUT this topic refers to.
Your help would be much appreciated.
Matt. 🙂
