G.E. Dryer has no hot air

I have replaced the heating element as well as the low start thermostat. I have power at the heating element since replacing the low start thermostat but still I am not getting heat. What other parts are involved in getting the heating element to power up? I am looking at a resistor as well as a capasator as to being the culprit. I would appreciate it if someone could point me in the right direction.:confused:
