We have had this oven for probably 7 years. A few years ago the bottom oven stopped heating up. I checked the internet before rushing out to buy a new element. Other people had had the same thing and said it was a fault with the oven. I seem to remember that the solution was to turn the switch on and off a few times then it started working again. The problem has come back and this time the turning off and on does not seem to help. I am now wondering if the element has indeed gone or if it is the switch fault again. Any suggestions how to find out or does anyone else have this oven with this fault?
