I've not had this problem because I always use new, OEM replacement parts.  I can't remember the last board I got bad out of the box although it does happen.  

 

Did you use an OEM replacement part for the ADC board and harness?  http://www.repairclinic.com/PartDetail/Defrost-Control-Board/5303918476/1614983?modelNumber=FRS6LR5EB3

Agreed.  Also check evap fan motor.  Even though fan motor is 120 volts power to fan is routed through defrost control.  Might cause issues with replacement control.

If I remember right, the wiring harness is changed when upgrading from ADC I, ADC II or ADC III. Wih that in mind, check and double check to make sure you connected the correct wires to their desired location. Eliminate the human factor.
