Microwave sensor cooking functions (e.g., sensor reheat, popcorn) do not work properly; food is undercooked or overcooked.

Safety: Unplug the microwave before accessing the sensor area.

• Clean cavity: Thoroughly clean the interior, especially near the sensor vent or grill, to remove grease and steam residue.
• Use proper containers: Follow KitchenAid's recommendations for sensor cooking (microwave-safe containers, vented covers).
• Inspect sensor: Locate the humidity sensor and ensure its opening is not blocked.
• Replace sensor: If sensor functions remain inaccurate, replace the humidity sensor with the OEM part.
