Ice not coming out dispenser, makes ice, door opens, not coming out. No water coming out dispenser. Replaced both switches. still nothing.
How to check for codes. The part EBR79159717 COST $232.25 FOR THE DISPENSER control board. I did not want to purchase if I don’t need it. Any suggestions? Thanks
As the door chute does open, this identifies the dispenser sub pcb at the top of the door is receiving operation signal to dispense ice. This would also suggest it is receiving operation signal when water should be dispensed as well. If it is not sending voltage to the water valve when the water paddle is pressed, or voltage to the auger motor when the ice paddle is pressed, the sub pcb is the likely cause of failure. The wires at the door hinge can be inspected for any indications of damaged wires to eliminate that as a possibility.

Thanks. After inspection of wires, and no visible damage. how would i test them? is there are code check that will tell if wires are not sending correct voltage? how to get code?
There would not be a way to get a code in this case as the water valve would not be a monitored device, and the auger motor circuit is driven by the sub pcb. However, the pcb can be tested for voltage output using the blue wire at the main control connection CON2 and the wires found on the sub pcb connection CON2. With a meter probe extension connected so that the blue wire can be used as the common neutral wire, voltage would be tested using the light blue wire at pin 4 when the ice dispenser is being pressed for crushed ice. There should be 115 Volts if the sub pcb is operating properly. The purple wire at pin 11 of the sub pcb would be tested for 120 Volts AC when the water dispenser is pressed. If voltage is found at either of these points, but neither of the parts operate, there is a wire harness failure either in the door or in the liner. The light blue and the purple wires at the door hinge connector can be tested for continuity to the same wires at the sub pcb after disconnecting the power supply cord from the power supply outlet. This would identify where a break in the wires could be. However, if there is not voltage at either of these test points when there should be, the sub pcb has failed.
