• Unplug the refrigerator from the 120V outlet for 60 seconds, then plug it back in to reset the control board
• Check that the refrigerator is fully plugged into a working outlet and the home circuit breaker controlling the kitchen outlet is not tripped
• Verify both the refrigerator and freezer compartment doors are closing completely and the door seals are not torn or damaged
• Inspect the air vents inside the refrigerator compartment to ensure they are not blocked by food items, containers, or ice buildup
• Remove any items blocking the air inlet vent at the back of the refrigerator compartment
• Listen for the evaporator fan running when the compressor cycles on—you should hear a faint humming or whirring sound from inside the unit
• Check that the refrigerator temperature setting is not set to the warmest position (verify it is set to a normal cooling level between 35-38°F)
• If equipped with an ice maker and water dispenser, verify the water supply line connected to the back of the refrigerator is not kinked or frozen
• Replace the air filter (if your model has one) as a clogged filter can reduce airflow and trigger the sensor
• Ensure the refrigerator has at least 2-3 inches of clearance on all sides and the back vent is not blocked by the wall or other appliances
