Dryer wont start, but has some power

Hello,

My Maytag dryer wont start. When I open the door, the light does come on. When I switch to any of the cycles and try to start it…nothing. However, when I turn the dial to any of the "off" positions, and press the start button, there is a slight "hummm." If I turn the "signal" button "off" (the one that alerts you when the cycle is complete), then I can’t even get the "hummm" noise/sound when I press the start button, even when it is in the "off" position. Any thoughts? Please?!?!
