Safety first: Disconnect electrical power before servicing. Microwave ovens can retain dangerous high voltage after unplugging. Internal microwave repairs and door-interlock testing should be performed by a qualified service technician. Never bypass a door interlock.

Restore the microwave door-sensing circuit with this ERP replacement SPST normally-open door interlock switch for compatible Whirlpool microwave ovens. A failed or worn switch can prevent the microwave from starting, cause intermittent operation, or prevent the control from correctly sensing the door position. The switch is rated 15 amps at 125/250 volts and uses 1/4-inch terminals. Verify the complete appliance model, original part, terminal layout, and ratings before ordering.
