Customer Questions and Answers for Refrigerator Dispenser Interface Assembly - Black by Ge

Hello Lonny, This sounds like you either have a bad connection at the dispenser board WR55X10304 or the board has failed. Check first at the bottom door hinge for broken or naked wires. If no problem is found, remove the dispense cover and check connections there. While there, check for about 18Vdc from the black wire to the blue wire. (Note the DC voltage at this point). This voltage should be supplied from the main control board at terminal J4-1, (black), to common J4-3 (Blue). If nothing is coming out of the main board, replace the main board WR55X10942C. If the voltages are present, replace the dispense board.
