How to replace a dispenser core control board in a side-by-side refrigerator
This DIY repair guide gives step-by-step instructions for replacing the dispenser core control board in a side-by-side refrigerator. The dispenser core control board is part of the fast-fill ice and cold water system; it connects to the dispenser motor, ice door motor and ice door heaters. The core control prevents water and ice from being dispensed if the freezer door is open. If ice and water are dispensed when the door is open, it's most likely that the core control board has failed. Replace the core control board using the manufacturer-approved side-by-side refrigerator part that fits your model.
Use this procedure on Kenmore, Whirlpool and KitchenAid refrigerators. The basic procedure for disassembling a dispenser also works on some GE, Samsung, Maytag, Amana, Frigidaire, Electrolux and Haier refrigerators.
