GE Profile PFE29PSDASS Ice maker duct door motor won't operate.

GE Profile PFE29PSDASS Ice maker duct door motor won’t operate. All other functions (that I can test) seem to work, ie. ice auger turning, water dispenses. I backprobed the connector J3 on door control board for power between pins 7 (duct door +) and 15 (duct door -) when the paddle is depressed and no power. I have 13VDC on the door control board between pin 17 (13vdc supply) and pin 20 (board gnd). The wire from the paddle switch that goes to the door control board tests good 13V when idle and 0V when paddle is depressed. Duct door motor operates when 12v applied at pins 7 and 15 (from wall AC adapter). Do I need a new door control board? Is there anything else I can do to diagnose?
