Re: my oven is completly dead its a diplomat ahy32
The first thing you need to check is the supply…most have a dedicated isolation switch (big red switch on a white box) which will be somewhere near the oven, if not on the wall then in a cupboard perhaps where they sometimes get inadvertantly knocked and switched off.
Sometimes, single ovens have a conventional plug going into a socket outlet (which again will be somewhere near the oven). If that’s the case you can check the socket by plugging another item into it to see if that works. If it does then you might like to check the fuse in the plugtop, and the wiring while you are there?
Failing the above then it’s time for an engineer really:?
