I switch on the main oven let it heat up and when I open the door it trips the mains fuse box shutting off all the circuits. I have had three electricians check everything and all they say is that they can find no fault. The oven has worked perfectly while they have been here, but as soon as they leave and I switch the oven on and open the door the same thing happens?

faulty door switch if fitted but not convinced ?
faulty element?.elements need insulaton testing with a meter at the time the appliance trips as when they cool they appear OK.Not really an electricians job.you need a GOOD domestic appliance engineer with correct test gear
