FIXED Whirlpool Duet Dryer does not start

Hello,

My whirlpool duet dryer stopped working. All the lights come on, but when i hit start, the machine stays on "sensing" and counts down, but nothing else happens.

Notes:
- I do not hear the motor turn or even hum likes its on.
- In diagnostic mode, when i press the start button, the display reads "-99"
- When i open the door (code reads "P:3E") and touch the moister sensor strips, the display beeps continuously and the screen reads "2:00".

Any help would be greatly appreciated. Thanks.

Check the thermistor resistance. It should measure about 11.9K ohms at room temperature.

Thanks for the help. Once I opened up the lower front cover, I saw the belt 661570V had come off the idler wheel 279640. I looped the belt back around and bought a new tri ring W10512946 to help the wheel intact. The dryer is back in action for now. All the codes in diagnostic mode stayed the same after the dryer starting running again so those must have been the expected values.
