MATAG FRENCH DOOR REFRIGERATOR NO ICE OR WATER COMING FROM DOOR. WHEN FLICKING THE DOOR SWITCH AND PRESSING THE DISPENSER BAR I CAN GET AN INTERMITTENT DISPENSING OF WATER OR ICE. THE AUGER MOTOR JUST MUMS AND DOES NOT TURN.
I JUMPERED THE REFRIGERATOR LEFT DOOR SWITCH AND CHECKED THE MICRO SWITCH WITH AND OHM METER. THE REFRIGERATOR HAS A CIRCUIT BOARD INSIDE THE DISPENSER PANEL AND A DOOR SWITCH DISPLAY PANEL. I SUSPECT THE RELAY ON THE ELECTRONIC CONTROL MODUAL BAD DUE DISPENSE MOTOR PULLING TO MANY AMPS WHEN TRYING TO DISPENSE

From the looking at the wiring diagram it the display pcb will send the 12vdc trigger voltage to the main control board which should be located on the back of the unit. The main control will then send the 120vac to the auger motor and inlet valves. I would say your likely on the right track with a bad relay. I cannot tell by the wiring diagram if there is an actual relay on the dispenser control board. Usually there is not. The only way to know for sure which board is bad would be checking to see if the dispenser board is sending the 12vdc trigger voltage to the main board. I would also check the wiring going into the freezer door at the bottom or under the hinge cover to make sure you dont have any broken wires. Hope this helps. Intermittent issues are always the toughest to track down.
