• Check that your Miele refrigerator is plugged into a properly grounded 120V outlet and verify the outlet has power using another appliance
• Verify your home's circuit breaker for the refrigerator is in the ON position; if tripped, turn OFF then back ON
• Ensure the refrigerator is level and stable—use a level tool to check, as tilting can affect sensor function
• Clean the condenser coils located at the bottom or back of the unit using a soft brush to ensure proper airflow
• Verify both refrigerator and freezer doors close completely and the gaskets seal tightly with no gaps or tears
• Check that refrigerator vents inside and behind the appliance are not blocked by food, ice, or debris
• Review and reset temperature settings to factory defaults (typically 37°F for fresh food, 0°F for freezer) per your user manual
• Power cycle the refrigerator by turning OFF the circuit breaker for exactly 60 seconds, then turn the breaker back ON to reset the control board
• Visually inspect the freezer interior for excessive frost or ice buildup around the back wall or sensor area—if present, allow defrost cycle to complete naturally
