Customer Questions and Answers for Microwave Door Interlock Support Bracket by Whirlpool

This is a plastic support bracket that holds the door interlock switch in the correct position inside the microwave. It ensures the safety switches align properly with the door latch mechanism so the microwave only operates when the door is fully closed. Replace this bracket if your microwave fails to start, runs with the door open, or if the interlock switch is misaligned or loose.
