Hi,

Our Kenmore Dryer has stopped heating again because the high-temp
cutoff switch opened. On 11/02 we had the same problem

Grounded heating element, poor air flow ( venting, vent hood, dryer
ducts ) bad operating thermostat could cause the heating element area
to overheat and trip the high temp cutoff.
