I have a customer with a KitchenAid SxS refrigerator KSRS25QXAL11 that is not defrosting. Defrost heater and defrost thermostat check good so that leaves the defrost ADC board as the culprit. Problem is the refrig has a defrost timer in it and not an ADC board as shown in the parts diagrams. There are several extra unused and unterminated wires in the control panel so it looks like somewhere along the line someone swapped out parts. Does anyone have a service manual, tech sheet, or wiring diagram for this refrigerator?
