Frank, You could check the DCV at the main control board on the back of the refrigerator. The J4 connector is the low voltage power out to the dispenser board WR55X10942C Remove the wiring harness connector, and check for 12 VDC across pin 2 and pin 3 and pin 1 to pin 3 on the control board pins. If you have the voltage the main control board is not the issue. Also check the pins and the receptacles on the board and harness to make sure there are no corrosion, moisture, etc. You'll also want to remove the dispenser board, and check the J4 connector for the same voltages on the same pin numbers, this will confirm the wire harness is not the issue, and you have the proper power supply to the dispenser board.
