Actually dismantled my non-working oven today. There's a huge chunk of element missing ... must've made one hell of a bang when that blew ... funny how it remained amongst the things the house's previous owners kept quiet. No wonder he avoided all eye contact when I passed him in the street. Anyway, no biggie - only £20 for a new one (element, that is) ... just need to remember where all the screws came from ...
