Why won't my dryer turn on

Uhm...

So why is this in the research subject?

Why is google.com your subject line?

And could you be a little more specific about the problem?

Its like asking why doesn't your car start? Well... did you use the key? Is there gas in the tank? Is there power from the battery? Et cetera...

So...

What kind of dryer? Make? Model? Gas? Electric? Explain more please...
