KitchenAid KBFN402EPA01 Refrigerator Makes an Unusual Noise After the Door Was Left Ajar

For the KitchenAid KBFN402EPA01, a door left slightly open can let warm air in and make the compressor and fans run more often until the compartments recover. First identify whether the sound is brief and linked to cooling, defrosting, ice, or water operation; then confirm the doors close, the gasket is intact, vents are clear, and the built-in cabinet is stable.
