• Check your home's electrical panel to verify the circuit breaker for the refrigerator is in the ON position; if tripped, flip it back ON
• Inspect the power outlet where the refrigerator is plugged in to ensure the connection is secure and tight
• Unplug the refrigerator from the wall outlet and examine the power cord for visible damage, cracks, or fraying
• Plug the refrigerator back into the outlet firmly, ensuring it is fully inserted
• Wait 60 seconds for the control board to reset, then check if the error code clears
• Verify that no other appliances on the same circuit are causing overload issues
• Check that the refrigerator is set to the correct temperature (typically 37-40°F for the fridge and 0°F for the freezer)
• If you have an ice maker or water dispenser model, inspect the water supply line connection at the back for any leaks or disconnections
• Allow the refrigerator 24 hours of normal operation to confirm temperatures stabilize and the error does not return
• If the error persists after these checks, the control board or power supply may require professional service
