Step 03
Safety Checks You Can Do
• Check your home's circuit breaker panel and ensure the refrigerator's dedicated circuit breaker is in the ON position; if tripped, reset it
• Verify the refrigerator is properly plugged into a grounded 120V outlet and the outlet is functioning (test with another appliance)
• Power down the refrigerator by switching off its circuit breaker for 60 seconds, then switch back on to allow the control board to reset
• Check that all refrigerator doors are closing completely and properly sealing
• Ensure the refrigerator is not positioned against walls or other appliances that could restrict airflow around vents
• Verify the interior vents and air passages are not blocked by food items or ice buildup
• Inspect that the back of the refrigerator has at least 2 inches of clearance from the wall for proper ventilation
• Check control panel settings to confirm no buttons are stuck or held down unintentionally
• Allow the refrigerator 24 hours to stabilize if there has been a recent power outage or electrical fluctuation
• Unplug the refrigerator for 5 minutes to perform a complete system reset, then plug back in and monitor for error code recurrence
