So my oven tripped the electric. When sort out fuse box main oven light on, indicator light on, can hear the fan, no heat.
there are four controls for start cooking time, end cooking time, timer, clock. Maybe nothing but just noticed the end cooking time keeps stating the same or more than the clock. Does this mean the oven thinks it should be turning off!. Have turned main off no change.

There is a thermal fuse on the left-hand side of the oven (once you have opened the back). In the middle is a little hole. This is a reset hole. Push a straightened paperclip into this hole to reset the fuse.

Check the timer/clock us properly set and switched to manual (find manual)

It'll probably be that the element has failed. Easy enough to change. There are plenty of videos available for those prepared to search
