• Unplug the freezer from the electrical outlet for 60 seconds, then plug back in to reset the control board and clear the error code
• Inspect the freezer door seal for cracks, tears, or improper sealing and clean the gasket with mild soap and water
• Check that all vents inside the freezer compartment are clear and not blocked by food items or frost buildup
• Verify the freezer temperature setting is correctly set between -10°F and 0°F on the control panel
• Ensure the freezer has at least 2-3 inches of clearance on all sides and that the back is not flush against a wall for proper ventilation
• Locate and inspect the defrost drain opening (usually at the back or bottom) and gently flush with warm water using a turkey baster if accessible
• Check that the freezer is level using a spirit level; adjust the front leveling feet if tilted more than 1/2 inch
• Confirm the freezer is not in a location below 50°F ambient temperature, as this can cause defrost issues
• Allow 24 hours after power reset for the freezer to stabilize before evaluating if the error persists
