GE Dryer GTD65EBSJ4WS Field Service Mode

[Orlando]

I have a new (3 month old) Sensor Dry, Dryer. Model GTD65EBSJ4WS . The control board died and after three months of service and when the service person (Sent by GE) replaced the board they initialized it to the wrong mode. To make matters worse they didn't know how to get into field service mode. 

Control board WE04X29097 is what was replaced and can't find how to get into service mode, any help would be greatly appreciated.

I found this under a different part number and it worked. This part # WE04X23887 was superseded by the above part number.

Press and hold the start key for 3+ second, while holding rotate the control knob 180 degrees and release. Refer to instructions for FSM settings. pressing power will exit FSM.  

Hope this helps someone.
