seams like if its unpluged for a long period if time then it shuts off.but if the timer keeps going why would it start back up after it hits the shut off part cause the timer will go through a cycle then stop like it supposed too but the timer keeps going and when it reaches the next cycle it starts right back up.and its not supposed too untill you press the start button. Even If I open the door and close it it starts right back up and before I had to hit the start button to restart it.
it reaches the intended shut off point and doesn't.
the timer mechanism is driven by a clock motor, the motor
has two switches that can turn it on. one switch is on the
timer shaft, that switch is on unless the timer is at zero;
the cam on the timer shaft shuts off a microswitch.
the other switch is the start switch, this must be
held closed (this moves the motor until the switch on the
shaft closes).
the switch on the shaft is a microswitch closed
by a cam. often these cams are positioned with
a set screw. if this cam has loosened and is slipping
it never pushs the microswitch causing it to open
and shut off the timer motor.
i don't have direct experience with your model
nor am i an appliance repairer, just some diy
skill.
as mentioned kenmore may have few user
serviceable parts or replacements without
replacing whole unit.
even if that is the situation often the
microswitch is the only easily replaceable
part. the switch is often a common
type used in many appliances.
so if the cam has loosened then it
might be able to be repositioned and
tightened. if the microswitch has
become disconneted the wire can
be reconnected. if the microswitch
has gone bad it might be able to be
replaced.
unplug the dryer and explore the timer.
just keep the screws straight and take
notes about what's what so you get
it back together.
