Does the Defy Slimline 600 oven have fuses to be replaced, because since last night the plate and oven dial switches on in the off positions and off in the on position, but no plates heat up. The power indicator light for each plate is also dimmer. Can you help?

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.
