A little late for Janet, but yes there is, on the back of the machine, a black rubber cover which you push to reset the thermal cutout. Wait 'till it's cooled a little. If it trips repeatedly, don't ignore it, it's probably clogged with fluff, and as with all tumble dryers, that's a fire risk if allowed to get out of hand. If you are feeling for the button, it is near the dead centre of the rear of the machine, a little to the left and slightly below the nut that holds the drum's centre in it's bearing.
Hope this helps someone,
