Linda, it is very unusual for both elements to fail at the same time. There is a common wire that runs from the back of the clock to both elements. If this wire breaks neither element will heat. I would disconnect the power to the range and pull it away from the wall. Remove the panels on the back of the range to expose the wiring to the clock and the elements. Inspect each wire from the elements to the clock. You might find the problem there. If the wires are ok and both elements stopped working at the same time, I would replace the clock. If one element stopped working and some time later the other element stopped working, the problem might be in the elements. When you are looking at the back of the clock, you can remove the screws that mount it and replace it. I hope this helps.
