Check your fuses or breaker. An electric dryer requires 240 volts to operate. In a fuse box system, 2-30 amp fuses are required for an electric dryer to operate. If 1 fuse is blown it will not start or heat depending on which fuse is blown.
In a breaker system the breaker can trip and sometimes look ok. Find your 30 amp dryer breaker and reset it by flipping the lever to off, then back on.
If this doesn't help, you may have a faulty door switch or maybe your door has loosened from the hinges and has sagged a bit, breaking contact with the door switch plunger.
If you can locate the door switch, push on the plunger... you should hear an audible click...if you do then the door switch is normally ok, but not always, it is just a simple test to rule a bad switch which is normally silent if it is faulty.
You may want to inspect for a burned wire or wire termination.
Make sure dryer is unplugged from the power source before inspecting!!!
Other than the previous instructions, it is difficult for a novice to diagnose the problem...call a technician in to fix your dryer.
1 more thing, Just because a breaker appears to be on, and/or you flipped it off then on, doesn't mean the breaker is ok. Fuses also can look good and be bad. A small volt-ohm meter($10.00) is a good investment for testing voltage, and to save time and money.

Hope this gets you up and running.

Sounds like the timer is going bad and it needs to be replaced. The time is located behind the knobs.
IF my answer has satisfied you please rate. Thank you

REMOVE YOUR ACCESS PANEL AND SEE IF YOU HAVE A BROKEN BELT IF NOT REPOST. ACCESS PANEL LOOKS LIKE IT COMES OF BY 2 SCREWS AND RAISING IT UP AND OFF.

The drive motor starting capacitor is likely dead. This can be tested if you are competent enough to take the thing apart and use an electronic multimeter. Otherwise it is a cheap part to replace, depending on how much the repair guy charges for labor and to be called out.
