Whirlpool Dryer Door Switch Parts — Models & Compatibility

Your Whirlpool dryer won't start when you press the button, or worse — the drum keeps spinning with the door wide open. Before you call a repair tech, check the door switch. This simple on/off mechanism is one of the most common failure points in Whirlpool, Maytag, and Kenmore dryers, typically wearing out after thousands of open-close cycles.

The 3406107 door switch (replaces WP3406107, AP6008561, 3405100, 3406109) is compatible with over 20 Whirlpool-family dryer models across multiple series. This hub helps you verify fitment and understand what you're dealing with before you order.

Is This the Right Part for Your Model?

Check your dryer's model number — it's usually on a sticker inside the door frame or on the control panel. Match it against the compatible models list below. Models like WED4800XQ0, MEDC400VW0, and LER4634JQ0 are confirmed fits. The switch mounts behind the front panel near the door latch, held by two screws.

If your model number isn't listed but starts with WED, MEDC, MGDX, or similar Whirlpool-family prefixes from 2005-2018, there's a good chance it'll work. When in doubt, pull the lint trap and check the existing switch's part number printed on the housing.

About This Replacement Part

The door switch is a simple on/off mechanism that prohibits the dryer from operating when the door is open. It typically fails due to wear or breakage, causing the dryer to not start or run with the door open. One user reported: "The part fit perfectly, arrived in a couple of days and was in original packaging. Watched repair video and repair only took 10 minutes."

Common symptoms pointing to a bad door switch include the dryer running with the door open, the drum not spinning when you close the door and press start, or the interior light staying off even when the door's open. The switch contacts wear down over time, especially if you've got a household that does a lot of laundry.

Installation Overview

This is an easy 15-minute repair — no special skills needed. You'll remove the lint trap, release two screws holding the duct, pull the dryer top forward to release clips, then prop it up. The switch is right there behind the door opening, held by two screws. Unplug the old one, plug in the new switch, button everything back up.

As one DIYer put it: "We followed the very clear instructions that were provided, easy peasy. Was exactly the part we needed and installed exactly the way they said. Husband did it, but I could have done it. Way cheaper than calling a repair person."

You'll need a Phillips screwdriver and maybe a 1/4" nutdriver depending on your model. Test your work by starting the dryer, then opening the door mid-cycle — the drum should stop immediately. If it doesn't, recheck your wire harness connection.

Why Door Switches Fail

Door switches fail mechanically — the plastic actuator arm cracks, the metal contacts pit from arcing, or the mounting tabs snap. If you've been forcing the door closed because it doesn't latch smoothly, you're putting extra stress on the switch. It's a wear item, plain and simple.

Sometimes you'll get intermittent behavior before total failure. The dryer might start some cycles but not others, or you'll hear the motor try to engage but nothing happens. That's the switch contacts making poor connection. Don't keep cycling it — you'll burn out the motor relay or worse.

What's Included

You get the complete door switch assembly — the housing, actuator arm, wire terminals, and mounting hardware. It's a direct OEM-equivalent replacement. No modifications needed, no adapters required. The wire harness plugs are keyed so you can't hook it up backwards.

Price is $26.99, which beats a service call by a mile. And since it's an easy repair, you're not paying someone $150 to do ten minutes of work. Keep the old switch as a spare if it's not completely destroyed — sometimes you can clean the contacts and extend its life as an emergency backup.
