XPARTCO 3406105 Dryer Door Switch Replaces WP3406105
XPARTCO 3406105 Dryer Door Switch Replaces WP3406105
The XPARTCO 3406105 is an aftermarket replacement dryer door switch assembly compatible with a wide range of Whirlpool-family dryers including Whirlpool, Kenmore, Maytag, KitchenAid, Amana, Roper, Estate, Crosley, Inglis, Admiral, Jenn-Air, Magic Chef, and Norge. The door switch is a safety component mounted inside the dryer cabinet near the door opening. When the door is closed, the door strike depresses the switch actuator, completing the circuit and allowing the dryer to start and run. When the door is opened, the switch opens the circuit and stops the dryer. On models with a broken belt detection circuit, the door switch also plays a role in belt failure detection. A failed door switch causes the dryer to either not start at all or to run continuously with the door open.
This is a Single Pole, Double Throw (SPDT) 3-wire switch with stainless steel terminals and a heat-resistant housing. It measures 1-3/4" L x 1-5/8" W x 1-1/4" H with a 7-3/4" wiring harness. Electrical specs are 120-240V, 50-60Hz, 11A, 1/3HP. The kit includes the switch and 3-wire harness assembly. It directly replaces WP3406105, 3406104, 3405104, 3405105, 528947, AP6008560, and several additional cross-reference numbers. Installs in 15–30 minutes with basic hand tools.

Installation Notes
Frequently Asked Questions
What does the dryer door switch do?
The door switch is a safety component that monitors whether the dryer door is open or closed. When the door is closed, the door strike depresses the switch actuator, completing the electrical circuit and signaling the control board that it is safe to run. When the door is opened, the actuator releases, opening the circuit and stopping the dryer immediately. On many Whirlpool-family dryers, the 3-wire SPDT switch also provides a secondary circuit used for broken belt detection — one of the switch's contacts is part of the motor start circuit, while the other is part of a safety cutoff circuit.
How do I test the door switch with a multimeter?
Unplug the dryer and disconnect the switch from the harness. Set your multimeter to continuity mode. The 3406105 is an SPDT switch with three terminals — typically labeled Common (C), Normally Open (NO), and Normally Closed (NC). With the actuator button not pressed (door open position), you should read continuity between C and NC, and no continuity between C and NO. With the actuator button pressed (door closed position), you should read continuity between C and NO, and no continuity between C and NC. Any deviation from this pattern confirms the switch has failed.
What is the difference between 3406105 and 3406104?
The 3406104 was the original part number, and the 3406105 (later updated to WP3406105) is the current replacement that superseded it. They are the same door switch and are fully interchangeable. The 3405104 and 3405105 are also cross-references for this same switch from earlier production. If your dryer's documentation or old switch label shows any of these numbers, the 3406105 is the correct current replacement.
Why does this switch have 3 wires when my old switch only had 2?
The WP3406105 is an SPDT (Single Pole, Double Throw) switch with 3 terminals — Common, Normally Open, and Normally Closed. Some older dryer models used a simpler 2-wire switch, but the 3-wire WP3406105 is the updated replacement that works on both older and newer models. On models that originally had a 2-wire switch, only two of the three terminals are used — the third is simply left unconnected. Follow your model's wiring diagram or take a photo of the original switch's wire connections before removing it.
Is this an OEM or aftermarket part?
This is an aftermarket replacement part built to OEM-equivalent quality standards. It is not a genuine Whirlpool OEM part, but is manufactured from durable plastic and metal with stainless steel terminals to match the dimensions and electrical specifications of the original WP3406105 door switch assembly.
