Hello, Thank you for using this service, I will be helping you with your problem today
this is one of two things, 1 the motor relay is bad and not staying in. or 2 the timer has a bad contact. sounds like the timer from what your saying about moving the cycle. heres a link to the parts. http://www.repairclinic.com/Whirlpool-Dryer-Model-GEW9878PW1-ID-651913-Parts?s=b5a8d651913e you can try replacing the relay first if you wish, its $22.00 and may take care of the issue. the timer is $92.00. hope this helps, thanks Bryan
We rarely use the timer, using rather the dryness sensor. Please note that this dryer has a ceramic sensor.
Appreciate the clarification. You are correct, it does not keep turning, just stops. Following this logic, it is likely not the sensors. I shall pursue the timer. Cross your fingers. Thanks!
