Whirlpool Dryer Door Switch Assembly Parts — Models & Compatibility

Your Whirlpool dryer won't start even though you hear the timer ticking, or worse — it's running with the door wide open. That's the door switch assembly failing, and the 3406105 is the direct replacement for over 20 Whirlpool, Kenmore, Maytag, and Roper dryer models. This hub covers which models use this switch and how to verify you've got the right part before ordering.

Is This the Right Part for Your Model?

The door switch assembly mounts inside the dryer cabinet where the door latch engages it. When it fails, you'll see two symptoms: the dryer won't start at all, or it runs with the door open — both safety issues. Check your model number on the inside edge of the dryer door frame or on the cabinet side. If your model number matches our compatibility list below and you're experiencing either of these symptoms, this is your part.

About This Replacement Part

The 3406105 door switch assembly replaces Whirlpool part numbers WP3406105, 3406104, AP6008560, and PS11741700. It's a simple mechanical switch that tells the control board whether the door is closed — when it wears out or breaks, the circuit doesn't complete. This is an easy 15-minute repair that only requires a screwdriver. You'll remove the top panel or front lower access panel (depending on your model), disconnect the wire harness, remove two mounting screws, and snap in the new switch. The part comes as a complete assembly, so there's nothing to adjust or calibrate.
