Hi, I have a zanussi built under double oven, yesterday when I was cleaning the top oven/grill I managed to snap a thin wire thing at the back of the oven. I don't know how else to describe it except it's a thin bit of wire right at the back top of the oven - it doesn't seem to be attached to the element -.the oven still works but how important is this bit? What's is it there for ? Do I need to replace it? I'm guessing it's not just decoration - I've looked through the manual - no mention of it. Does it make the oven/grill dangerous ? Sorry if stupid question but I'm going away on Monday & have a house sitter don't want to risk electrocuting the girl - she seems like a very nice young woman. Any help most appreciated. Thanks
