I have a 12 year old Kenmore Dryer, Model 90 Series, #66904690.
The dryer was functioning perfectly and just quit running. I have 240 volts
At the dryer, continuity on the door switch, start switch, all thermostats and the
Thermal fuse. When I push the start button, I can see that the timer motor is running.
When I hold in the start switch and advance the time, I hear a slight buzzing sound as I pass
By each cycle.
The dryer was running normally with no unusual noises which makes me not suspect
The dryer motor. The only parts I have not checked out are the motor and the electronic
Card. Any ideas?
Thanks, jmchris
