The oven's been making a very loud rattling noise recently as if the fan was catching on something, so today I thought I'd take the back panel off and see if there's anything obvious. Curiously it only makes a noise once its got up to temperature, so there's some thermal expansion/contraction effect going on... regardless, I decided to check as if the fan is catching on the element then at some point it'll wear through and let the magic smoke out in spectacular fashion.
So, can you spot what's wrong in this photo?
I'll give you a hint: there's two problems. Not only is the fan catching on the element (in fact, the edge of the fan blade is jammed right up against it)...
...but the element is no longer quite circular, and where it's become kinked the outer casing has split:
Time to get in touch with the landlord and get it sorted, otherwise it'll only blow the element halfway through cooking something or other. That'll be the second oven repair/replacement - the last one was a bit over four years ago.
