Safety Checks You Can Do

Steps you can try at home safely

• Check your home's circuit breaker panel and ensure the breaker controlling the refrigerator is in the ON position; reset it by switching OFF then back ON if tripped • Verify both the refrigerator and freezer doors are closing completely and latching properly • Confirm the temperature settings have not been accidentally adjusted to the warmest setting • Inspect the refrigerator's air vents inside the fridge and freezer for any blocked items, ice buildup, or debris restricting airflow • Clean the condenser coils located on the back or bottom front of your refrigerator using a soft brush or coil cleaning brush (ensure appliance is unplugged) • Verify there is at least 2-3 inches of clearance on all sides of the refrigerator for proper air circulation • Unplug the refrigerator from the wall outlet for 60 seconds, then plug it back in to perform a hard reset of the control system • If accessible, check that the refrigerator is level using a level tool; adjust the front legs if necessary to ensure proper drainage and cooling • Wait 15-20 minutes after power restoration to allow the system to reinitialize before determining if the error persists • Contact a certified KitchenAid service technician in your area if the error code reappears after these troubleshooting steps
