More than one component could be at fault. Does it produce heat in the delicate or low heat setting? This is often a midpoint tap which uses only half of the total heating coil. Also, there is a high safety thermostat, which won't allow any heat if it checks out. The limit thermostat(s), when activated by respective high drum heat, cause the timer to advance while cutting off current to the heating element. The inter-relation of the two means that further diagnostics is needed. Parts are relatively inexpensive and you can do a lot of rebuiliding on an old Kenmore before the cost of a new dryer is reached. I've got a pair in my basement, and they have been good to me.
