Whirlpool, Maytag & KitchenAid Dishwasher Door Latch Assembly Parts — Models & Compatibility

Your dishwasher won't start, and you've checked everything — power's on, door's closed, controls light up. The culprit? A failed door latch assembly that's preventing the safety interlock from engaging. This hub covers the W11091934 door latch assembly that fits across Whirlpool, Maytag, and KitchenAid dishwasher lines, including the popular MDB, WDTA, and KDTM series models.

Is This the Right Part for Your Model?

The W11091934 latch assembly works across multiple brands because Whirlpool Corporation manufactures all three. To verify compatibility, locate your model number on the inner door frame — you'll see it when you open the dishwasher door, typically along the top or side edge. Cross-reference that number against the models listed below. This part replaces older part numbers W11412299, AP6980078, and PS12745375, so if you're holding an old latch with any of those numbers stamped on it, this is your replacement.

About This Replacement Part

The door latch assembly is the mechanical interlock that tells your dishwasher it's safe to start a cycle. When it fails, you'll experience the classic symptom: the dishwasher simply won't start, even though everything else appears normal. The latch mechanism includes both the strike that catches the door and the switch assembly that signals the control board. Over time, the plastic components wear down from thousands of open-close cycles, or the internal spring mechanism weakens. Some units develop cracks in the housing from hard door slams or shifting during cycles. The W11091934 is a direct factory replacement — same mounting points, same electrical connector, designed to restore that positive click and reliable door closure you had when the dishwasher was new.
