If your KitchenAid refrigerator appears dead or not running, the most likely culprit is a failed dispenser control board; inspect the board for burn marks and replace it if it looks damaged. Next, rule out an incoming power problem by making sure the plug is fully seated, the outlet is supplying power, and no breakers or fuses have tripped—avoid using a GFCI for a fridge. If the display is still dead, the user control and display board can also fail and should be checked for damage. Loose or damaged wire harness connectors between the panel and control board are a common, easy-to-fix cause, and a simple power reset—unplugging the fridge for a few minutes or switching the breaker off and back on—can restore operation after a surge. A failed main control board is possible but less common, so test the other parts first.

Ensure plug is tightly pushed into a regular electrical outlet and the outlet is supplying power. Using a ground fault outlet for a refrigerator is not recommended. Confirm that no circuit breakers have tripped or fuses have blown.

03 - KitchenAid Refrigerator User Control and Display Board
If the refrigerator display appears completely dead, it's possible the user control and display board has failed. You should inspect the board for any burn marks and replace it if it appears damaged.
The wires from the control panel to the control board may be loose or have become disconnected. Make sure the wire harness connectors are tight. A damaged wire harness will need to be replaced.
Common
05 - Power reset
After a power surge or power outage, refrigerator operation could be temporarily affected. Full operation can sometimes be restored through a power reset by either unplugging the appliance's power cord for a few minutes and then plugging it back in or switching off the circuit breaker for the refrigerator then switching it back on.

06 - KitchenAid Refrigerator Control Board
If nothing is working on the refrigerator, it's likely the control board is defective. However, this is almost never the cause. Before replacing the main control board, test all of more commonly defective parts. If none of the other components are defective, consider replacing the control board.
