Purpose

Details
The W11197766 is a genuine OEM door interlock (safety) switch assembly for Whirlpool microwave ovens. It ensures the microwave cannot run while the door is open, providing a critical safety function. If this interlock fails, the microwave may refuse to start, show “door open” errors, or run with the door open (unsafe). Replacing the assembly restores correct door-sensing and safe operation.
