• Check your home circuit breaker to ensure the refrigerator breaker hasn't tripped; reset if necessary
• Verify the refrigerator is plugged in securely to the 120V outlet and the outlet is functioning with another appliance
• Ensure both refrigerator and freezer doors are closing completely with proper sealing; inspect door gaskets for damage or debris
• Confirm temperature settings are not set to the warmest position; adjust to recommended cooling levels (typically 35-38°F for fridge, 0°F for freezer)
• Clear any visible obstructions blocking the rear vent openings and air circulation paths
• Unplug the refrigerator for 60 seconds, then plug it back in to perform a complete system reset
• If accessible on your model, gently clean dust and debris from the condenser coils and fan area at the rear or bottom of the unit
• Check that the refrigerator has adequate clearance (at least 1-2 inches) on all sides for proper air circulation
• Verify that vents inside the refrigerator compartment are not blocked by food items
• If error persists after these steps, contact a certified Miele service technician or call 1-800-991-MIELE for professional diagnosis
