That's the basis of my query: Can anyone tell me what might be causing this, what to check and how to fix it so it doesn't happen again? I do not want to risk fire when I am not around to monitor what's going on with the oven, but at the same time, I do not want to replace it. I have looked at getting another oven, but there's nothing that I like as much as my Samsung. It has the size, the looks and the advanced controls (ie. one touch, defrosting, etc) that I like.
This is a pic of what the damage looks like on the interior:
