Whirlpool WP4387911 Door Light Switch for Refrigerator

The Whirlpool WP4387911 is a refrigerator door light switch that functions as a basic on or off mechanism activated by the refrigerator door. When the door-closed the switch engages, turning off the interior-light and starting the compressor to maintain the proper temperature for stored food. Conversely, when the door is opened, the switch is disengaged, activating the light for visibility and potentially signaling the compressor to pause, depending on the specific refrigerator model. This component helps to conserve energy by eliminating unnecessary lighting and managing cooling cycles based on door activity. The WP4387911 is used in various Whirlpool refrigerator models and is also compatible with several other brands.
