Genuine Whirlpool Replacement Part

Interlock assembly (part number W11449274) is for microwaves.

The interlock assembly holds the microswitches that control the on/off and start/stop functions of the microwave related to the "open" button.  Malfunctions of this part can cause intermittent functioning, inability to start, or inability to stop the microwave from running.

Always disconnect from all power sources before beginning work. Be sure to replace switches in each position with the same type in the same orientation.
