Whirlpool Microwave door interlock switch; two-terminal, normally closed W10269458, Replaces W10211973, 8206347, 4393598

Genuine Whirlpool OEM microwave door interlock switch. The switch prevents the microwave from operating when the door is open and is specified as a two-terminal, normally closed switch.

Is This the Right Part?

Common Symptoms

• Microwave displays a door-open or close-door message when the door is closed.
• Microwave starts intermittently or stops after a few seconds.
• Microwave may fail to heat when the door is closed.
• Door-related operation may be inconsistent, especially when the door is closed with insufficient latch engagement.

Check Before Replacing

• With the appliance unplugged, inspect the switch body, actuator, terminals, and surrounding latch or switch-holder area for visible damage or looseness.
• Confirm the door closes fully and that the latch engages the switch actuator without excessive movement or misalignment.
• If qualified to perform electrical testing, disconnect the switch wiring and check continuity against the appliance service documentation, comparing the switch behavior with its specified normally closed configuration.
• Do not operate the microwave with the door open; after any interlock repair, proper door alignment and interlock operation should be verified before use.
