Safety Checks You Can Do

Steps you can try at home safely

• Check your home's circuit breaker panel to ensure the refrigerator's dedicated circuit breaker is in the ON position; if tripped, switch it fully OFF then back ON • Unplug the refrigerator from the wall outlet or turn off its circuit breaker for 60 seconds to perform a complete electrical reset, then restore power and observe if error clears • Verify that both the refrigerator and freezer doors are closing completely and making a tight seal with no obstructions • Confirm that temperature control settings are adjusted to recommended levels (typically 37-40°F for refrigerator, 0°F for freezer) and not set to extreme positions • Inspect the refrigerator's rear exterior for blocked air vents or condenser coils covered in dust; gently vacuum accessible coils and vents with a soft brush attachment • Ensure the refrigerator is positioned with at least 1 inch of clearance on all sides, especially the back and top, to allow proper airflow for cooling • Check that nothing is blocking the interior air vents between refrigerator and freezer compartments • Examine the power cord for any visible damage, cuts, or pinching; ensure the plug is fully inserted into the outlet with no loose connections • Allow 24 hours after troubleshooting for the refrigerator to stabilize and confirm the error code does not return
