Whirlpool WPW10472384 Microwave Bulb Light

The Whirlpool WPW10472384 is a replacement bulb made exclusively for Whirlpool microwave ovens. You can watch your food cook thanks to a tiny, usually halogen lightbulb that illuminates the microwave's interior. The filament within the lightbulb heats up and emits a bright glow when the electrical current is turned on. This light helps you keep an eye on the cooking process of your food, avoiding over- or undercooking. A functional microwave light bulb improves your whole cooking experience, particularly for meals that require visual signals, such as checking on the browning of cheese or the melting of chocolate. While not crucial to the WPW10472384 microwave's primary function of heating food, a burnt-out bulb might make using the microwave less convenient.
