Introduction
Whirlpool microwaves use door switches as part of their safety system. These switches ensure the microwave only operates when the door is securely closed.
If the switch fails, the microwave may refuse to start or may stop during operation.
How the Door Switch Works in Whirlpool Microwaves
Whirlpool microwaves typically use two or three switches mounted inside a small bracket near the door latch.
When the door closes, the latch presses these switches and signals the microwave control system that the door is closed.
If one of the switches fails, the microwave may behave as if the door is still open.
