The timer does not advance on auto dry settings only, also seems like it was taking longer to dry on this setting.Disconnected rear vent and made sure lint trap was cleaned and there was no change.
ANSWER Hello Dave,
If you have tried the unit without the duct connected, the issue will be one of three things. An open timer motor, a bad centrifugal switch in the motor, or timer switch "0" not making electrical contact. The timer motor will show a resistance, but should not read open or zero resistance. The centrifugal switch will read open unless the centrifugal weight is pushed against the spring tension to simulate the motor spinning the weights out. The timer contact "0" can be checked by testing from the timer motor wire to the orange wire or the white wire with a black trace, depending on the position of the timer knob. This connection, if good, will show zero resistance when the contacts close. This can be determined by studying the wiring diagram. The wiring diagram should be either in the control panel or it is sometimes glued to the rear of the unit.
