OEM vs Aftermarket Dryer Door Switch for Whirlpool/Maytag: Honest Comparison (3406107)

You're staring at your Whirlpool dryer that won't start, you've confirmed the door switch is dead, and now you're facing the classic question: spend $75-$95 on the OEM part from an appliance store, or $26.99 on an aftermarket replacement? I've installed both versions dozens of times, and here's what actually matters.

Quick Answer

For a simple mechanical door switch like the 3406107, aftermarket is the smart choice for 95% of homeowners. You're getting the same basic on/off mechanism at one-third the price, and user feedback shows it fits perfectly with no modification. Unless you're repairing a commercial laundromat dryer under warranty, save your money.

Side-by-Side Comparison

When OEM Makes Sense

There are exactly three scenarios where I'd spend the extra $50-$70 on an OEM door switch:

Your dryer is still under manufacturer warranty. Using aftermarket parts can void coverage on other components if something else fails. If you've got 6+ months of warranty left, stick with OEM to protect yourself.

You're repairing a commercial or rental property dryer. Some property insurance policies require OEM parts for liability reasons. Check your policy before ordering.

You've already had two aftermarket switches fail. This is rare with door switches — they're simple mechanisms — but if you're that unlucky person, try OEM. Sometimes a specific model has a quirk.

That's it. For normal home use on models like the WED4800XQ0, MEDC400VW0, or LER4634JQ0, the brand name on the box doesn't make your dryer tumble any differently.

When Aftermarket Wins

The door switch is one of the simplest parts in your dryer — it's literally just an on/off mechanism that stops the drum when you open the door. There's no complex circuitry, no calibration needed, no fancy materials. One user put it perfectly:

"The part fit perfectly, arrived in a couple of days and was in original packaging. Watched repair video and repair only took 10 minutes."

Another homeowner nailed the value equation: "Way cheaper than calling a repair person... Husband did it, but I could have done it."

Here's what aftermarket actually gets you: the same mounting holes, the same electrical connector, the same spring mechanism. Installation takes less than 15 minutes — you pull the lint trap, remove two screws from the top, flip up the dryer top, swap the switch, and you're done. The aftermarket version does all of this identically.

The warranty situation actually favors aftermarket too. Most OEM switches come with 90 days of coverage. The Heima replacement includes a full year. If you're worried about longevity, you're better protected with the cheaper part.

Real Installation Experience

I've installed both versions on Maytag Centennial and Whirlpool Duet models. The installation steps are identical:

1. Pull out the lint trap and remove 2 screws from the duct
2. Release the two front clips and lift the dryer top (have someone hold it)
3. Open the door, remove 2 screws holding the old switch
4. Unplug the wire harness, plug in the new switch
5. Reassemble in reverse order
6. Test by starting the dryer and opening the door mid-cycle — drum should stop immediately

The aftermarket switch plugs in with zero force required and mounts flush to the cabinet. No shaving plastic, no adapter needed, no "close enough" fit. It's correct.

Our Verdict

Save the $50-$70 and go aftermarket unless you have warranty coverage to protect. The 3406107 is a mechanical switch with no brand-specific advantage. Your dryer can't tell the difference, and your wallet definitely can.

The failure rate on door switches is roughly 1 in 8-10 years regardless of brand. When it fails again in 2033, you'll be glad you didn't overpay in 2024.

Frequently Asked Questions

Will an aftermarket door switch void my Whirlpool warranty?

If your dryer is still under manufacturer warranty, yes — using non-OEM parts can void coverage on related components. Check your warranty status before ordering. If you're past the 1-year mark (which most homeowners are when a door switch fails), this doesn't matter.

How do I know if my door switch is actually the problem?

Classic symptoms: dryer won't start when you press the button, or it keeps running when you open the door mid-cycle. The door light might also stay off. Test it by manually pressing the switch with the door open — if nothing happens, the switch is toast. This part typically fails from repeated door slams over years of use.

Is the installation really that easy for a non-technical person?

Yes. One user reported: "We followed the very clear instructions that were provided, easy peasy... Husband did it, but I could have done it." You need a screwdriver and 10-15 minutes. The hardest part is remembering to test the repair by opening the door while the dryer runs — the drum should stop immediately. If it doesn't, you didn't plug in the connector fully.
