Admiral Heavy Duty Giant Capacity Plus?

I came home to wet clothes in the dryer. First thing I checked was to make sure the plug hadn't fallen out somehow but it hadn't. I checked the circuit breakers and nothing. I even tripped it then reset it but nothing. When I turn the dial, I can hear a little clicking noise so I'm thinking that electricity is getting to the unit, yet the light doesn't come on at all when the door is open. What else can I check? The unit will be 10 years old this September but this is the first problem I've ever had with it.
