My client says that her 'hot' burner stopped working. Is it possible that the element is burned out?
If the hot indicator light stopped working then it would be a bad light. If the burner is not working then you would want to check to see if the switch is bad. This can be done by checking the switch in the on position and checking from H1 to H2 for 240vac. If there is proper power then replace the element and if there is not power then the element.
