The dryer is doing what others report pointing to a dirty moisture sensor; only will dry in manual mode. I tested the thermistor good, high limit good, etc before I noticed a possible missing sensor bar. When looking deeper I noticed I only have one sensor bar (top one). It appears the bar is missing that once connected to the black wire on harness 3406653. The end of the sensor strip was still connected to the harness and looks like it was broken free from the bar. The red/yellow wire's strip is intact. Am I assuming correctly there is suppose to be two bars sensing resistance between the pair? If so, please direct me to the proper part. Thanks again.
ANSWER Hello Carl,
Yes there are supposed to be 2 sensor bars 3387223 on unit and will not work in the auto setting if one of the bars is missing.
