I went to this single oven to find the cooling fan runs all the time unless switched of at mains.The local handy man had a go and now this is the result.The initial fault i found was only fan element gone,simple now she says this problem has arisen since he touched it.Have put new aeg fan element in just got to sort this out.cant see the model no worn off,any one got a wiring diagram,please. 🙁
