Kenmore 110.62802101 Dryer - no heat

Drum rotates but no heat - where to start diagnostics? Thermostats? Thanks

Thermostat would be where I would start.  I used a knock-off brand originally...lasted a week...before going with an OEM.  Ultimately, within a year, however I was replacing the heating element itself (corroded through in one spot) - no issues since.

Check first, of course, for a tripped breaker and proper voltage at the outlet.  Then the element thermal cutoff (fuse) on the heater box is the first suspicion.  It interrupts power to the element but the motor runs.  Then the high-limit thermostat on the heater box.  Check the element for continuity, and short-to-ground which is a common cause of blowing the fuse.  The fuse also serves as a fail-safe for the high-limit thermostat so they're usually replaced as a set, particularly if the element is not shorted.  The other thermal fuse on the blower housing will stop the motor from running.  It serves as a fail-safe for the operating thermostat on the blower housing.

The most likely cause will be blown thermal fuse. If so check ventilation for clogs. 
 

If not thermal fuse behind back panel then investigate your heater and cutoff.

Start with voltage at the wall then work your way back to the heating circuit via the wiring diagram
