If your supply is 220v you can use it off a 13A plug. If 110V No.

If it is a fan assisted oven , and the fan is working o/k, then it is likely to be the element that has failed.
This is located at the rear of the oven compartment behind a removeable cover.
I the fan is not working as well, then could be a faulty thermostat that controls the heating function.

I have searched diligently and cannot find what the interior of the oven is made of. I suggest you open the owner's manual and find contact information for the manufacture. Call or email them for an answer.

There does seem to be a fault, as the fan should run continuously even when the element goes off at the required temperature setting, and the light should atay on as well.
It suggests to me that there is a fault with the oven thermostat, or it is wired incorrectly.
