MED5740TQ0 Dryer not advancing in Auto Dry

[bimbbobway]

mod# MED5740TQ0  ser# MW2132760

Will not advancing in auto dry,  it does advance , dry and work normal in Timed Dry 

"Timer"and "auto dry control board" have been replaced. 

Timer in Auto and Timed dry: (Blue loop on the diagram)We can confirm the sensor circuit  reads INF OHMS with nothing on it and it does register resistance when it makes contact with wet clothes. 

Timer in Auto and Timed dry: From the Orange White (Red dot on diagram) wire to ground we have 120V ac  

Timer in Auto and Timed dry: From the Tan/white wire (Blue Dot on diagram) to the Neutral on the pigtail we have a closed circuit so we can confirm we get neutral. 

Timer in Auto and Timed dry: From white/black (Black Dot on the diagram)  we do not get neutral in any timer position. 

As I read this the way it works is when in auto dry the dry control board opens the neutral ro the timer motor to pause the timer.  It does work in timed dry and will not advance in auto dry.  We have checked the conector, retaken these reading multiple times.  We have a new timer and dry board,  what am I overlooking?

I HAVE TRIED TO UPLOAD A PICTURE OF THE SCHEMATIC AND WIRE DIAGRAMS BUT I CAN NOT FIRE OUT HOW, IT ONLY GIVES ME THE OPTIONS TO ADD A URL OR USE EXISTING PHOTO

Timed dry cycle set on timer with regular and low heat setting on ,  you should be getting a neutral reading from  White/Black  to  T       In automatic timer cycle setting regular heat, there is no neutral reading at the Black/white

Thanks, so it must be a bad timer.

You stated that you replaced the timer already...Is the cycling thermostat operating properly and sending current to the timer?

go over the wires on the timer you replaced and you may have crossed a wire some where also.  You have the schematic so you can check the wiring
