I have a Whirlpool Gold Senseon dryer Model: GEX9868JQ0 which just quit working. Until today never gave me any problems. When I select the cycle and press "Start" I hear the relay clicking, but won't start and the "Drying Status" red indicator light "Sensing" is flashing rapidly. I have tested the air duct fuse, still good. I have pulled out the "thermistor" and checked the impedance with my ohm meter, the value was dropping while applying heat from a hair dryer. Door switch also looks good, when I press on it the light goes off. I am clueless.
Has anybody had the same problem?

Update:
Just ran complete on board diagnostics and everything looks fine, but the motor won't start. Also measured voltage at P1 connector and I got 118 volts across pin 1 (black) and pin 4 (white). I didn't get anything between pins 2 and 3 (light blue/dark blue). The diagnostics manual tells me to replace the circuit board. Is this right?
Any comments?

Did this user ever get a reply? I have the same issue. I haven't tested the P1-1/P1-4 pins and I'm not sure if I get a sensing light.
