Unplug the unit. Using a ohm meter you need to check of the heating element is good or not. Reading across it you should see very low resistance. If you don't it may be "open" or a thermal interrupt has stuck open preventing current flowing through it. Check your high and low limit switches (sensors) for closed circuit (low resistance). If one reads high or open that one needs to be replaced.
