Customer Questions and Answers for Latch, Door by Whirlpool

Hello B., This indicates an issue with the door lock/unlock circuit. As per the tech sheet: 1. Check the latch assembly: latch arm pivot joint, arm/motor connection, plunger and hook springs. 2. Check the Latch Motor: - Check for firm electrical connections. - Disconnect the two wires from the motor and measure the resistance of the motor. The resistance should be approx. 2450O. If the motor is open (8O) or shorted (0O), it should be replaced. 3. Check the Latch Switch. Disconnect it and use a continuity tester: - Door latched = switch closed, continuity should read 0O. - Door unlatched = switch open, continuity should read 8O. 4. Check Door Open/Closed Switch. Disconnect it and use a continuity tester: - Door open = switch open, continuity should read 8O. - Door closed = switch closed, continuity should read 0O. 5. Check Sister Board. - Check connections, latch motor – sister board. - Replace sister board. 6. Check power and element connections. 7. Replace control.
