problem = timer doesn't move from the position it started at and the dryer turns but i get no heat...vents clear and when i opened the dryer few days ago to check it out i ran a cycle to see what happened and it just happened to be 1 of the 20 times that the dryer actually works so that seems to suggest that its something like..timer/sensor/switch?? I would greatly appreciate ANY help on this..thank you much, jay.

timer doesn't move from the position it started.

is that in the Auto Dry Cycle ?
try it in the Timed Dry Cycle.

Yes it does work in timed dry

does it now heat ?

In the Auto-Dry Cycle, the Timer Motor is controlled by the Dryness Control Board
(two different types used on your model)
6-pin Board with separate Chime
14-pin Board with built-in Chime
But it doesn't control the Heater
you may have another problem

The Dryness Sensor could be "clogged" with fabric softner

And I also unscrewed the sensor bar and cleaned it as much as i could....when I took it off i noticed it has a total of 4 terminals(2 on each end) the only wires that are connected to it are 2 on one end of the sensor..the two terminals on the other side are not connected to anything and they are bent almost flat against the sensor...is this normal?

In the Auto-Dry Cycle, the Timer won't move until the Sensor senses the clothes are nearly dry.
If there's no heat, the Timer won't move (on the Auto-Dry Cycle)

Does the Ignitor glow at all ?

that may be normal,
Cabinet must be assembled for correct air-flow,
or the Thermostats may trip.
