A KitchenAid oven that turns on and produces heat but consistently leaves food undercooked can be difficult to diagnose. The oven may appear to operate normally: the display works, the heating cycle starts, and the interior becomes warm. However, if the actual temperature is significantly lower than the selected setting, food may take much longer to cook or remain raw in the center. Several components can cause this problem, but the temperature sensor and heating elements are among the first parts technicians typically inspect. Understanding the symptoms can help you determine when professional KitchenAid oven repair is necessary.
