If your refrigerator has stopped running and the front display looks dead, the most likely culprit is a failed dispenser control board, so inspect that board for burn marks and consider replacing it first. The next-most-likely cause is an incoming power problem, so verify the plug is fully seated in a working outlet, avoid using a GFCI for long-term use, and check breakers or fuses. A failed user control and display board is a common follow-up, and loose or damaged wire harness connectors between the panel and boards can also cause a dead display or unresponsive buttons. A simple power reset by unplugging the fridge or switching the breaker off for a few minutes will sometimes restore operation after a surge. The main control board is less commonly the issue, so test the more likely parts before replacing it.

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.

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 - Universal 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.
