I have a Kenmore electric dryer of unknown age.
The symptom was the standard "no heat."
I tested the reg / low thermostats and the hi limit thermostat. Those tested
out ok. I was next going to test the heating coil itself, so I plugged the
dryer in. To my surprise, the heating element came on, even though the dryer
motor was not running.
As far as I can tell, it doesn't matter what position the timer motor is in.
The heating element comes on whenever the dryer is plugged in.
Any thoughts? My guess is maybe a defective centrifugal switch?
