Whirlpool Microwave door switch, three-terminal W10727360, Replaces W10269457

Genuine Whirlpool OEM three-terminal microwave door switch rated 16 amps, 125/250 volts AC. The switch operates as part of the microwave door-interlock system and prevents operation when the door is open.

Is This the Right Part?

Common Symptoms

• Microwave will not start with the door closed
• Microwave runs for a few seconds and then stops
• Microwave does not heat because the interlock circuit is not completing correctly
• Microwave continues operating or does not shut off when the door is opened
• Intermittent operation associated with opening or closing the door

Check Before Replacing

• Disconnect power before accessing the switch or removing any appliance panels.
• Check that the door closes fully and that the latch hooks visibly engage the interlock actuator without excessive looseness.
• With power disconnected, inspect the switch and nearby wiring for burnt terminals, arcing, melted plastic, loose connections, or mechanical damage.
• If qualified to do so, test the switch terminals for the correct continuity changes with a multimeter while manually actuating the switch; compare results with the appliance service documentation.
• Do not operate the microwave with panels removed or bypass, short, or defeat any door-interlock switch.
• After interlock repair, have the microwave's interlock operation and required radiation-leakage safety checks verified according to the model's service procedure.
