My oven seems to trip my house electrics when set above 150 degrees C. Everything works fine below this temperature, but as of recently it just takes a minute or so for the power to trip if I set the oven even a few degrees over 150. Is this a fault you've encountered before? If so, is it the element? I think we bought this oven 8 or 9 years ago so maybe it's time for a new one.
