I just noticed another post that described a similar problem and another problem that seemed to arise simultaneously- the timer won`t go off until switched off manually. Came in handy the first time as the clothes came out dry after being in there all night (it was Halloween, I was a little spooked to wake up to the dryer still running :) ) .... anyway, if johnnymac`s post is accurate, this sounds like something more on the electrical side and not as simple as swapping out a heating coil, fuse or thermostat.... I can`t be messing around with 240v so I guess I`ll have to call in a pro.

Try resetting your AC panel breaker for the dryer. Sometimes the L2 leg can trip without tripping the whole breaker. Drive motor would still work but no heat. If that isn't it, check for 240vac at power cord terminal block on back of dryer. Should have 240vac between two outside terminals and 120vac between each outside terminal and the center terminal. If good, problem could be faulty motor switch or timer assuming you have checked the hi limit thermostat, thermal cutoff, heat element and operating thermostat.

Parts manual is here.

Wiring diagram is 3406689 and should be inside your control panel.
