The switch detects the dryer-door position and helps prevent operation with the door open; documented symptoms include failure to start and running with the door open. Part WP3406105 Previous 3406105, 3406104, 3405105 Substitute 3406105CM, DE6105 Whirlpool Whirlpool Dryer door switch assembly WP3406105 Whirlpool OEM dryer door switch assembly. The switch detects the dryer-door position and helps prevent operation with the door open; documented symptoms include failure to start and running with the door open. ❓ Is This the Right Part? This is the correct fix if ALL of the following are true: ✔ QUALIFIER 1 — dryer powers on and receives correct incoming voltage ✔ QUALIFIER 2 — thermal fuse, start switch, timer, and motor have been confirmed functional ✔ QUALIFIER 3 — door switch has been tested and confirmed failed (open circuit when door is closed) ✔ ONLY problem is dryer not starting with door closed, or drum running with door open Not sure? Send us your model number — we’ll confirm before you order. 🔧 Common Symptoms Dryer will not start when door is closed — no response when start button is pressed Drum continues to run after door is opened during a cycle Door switch clicks but dryer does not respond to door position Door switch confirmed open or failed on continuity test with door closed ✔ If these symptoms match and the door switch is confirmed failed, this is the correct OEM replacement. ✔ In most cases, replacing a confirmed failed door switch restores normal start and door-safety operation immediately. ✅ Cross Reference Information Part Number: WP3406105 Previous Part Numbers: 3406105, 3406104, 3405105, 3405104 Documented Substitutes: 3406105CM, DE6105 Part Details Part Number: WP3406105 Part Type: Dryer door switch assembly Manufacturer: Whirlpool Appliance Type: Dryer ⚠️ Recommended While Repairing: While the door panel is open, inspect the thermal fuse and start switch — both are accessible in the same service area and are common companion failures. Testing and replacing worn components at the same time avoids a second service call if another component fails shortly after. ⚙️ Installation Skill Level: EASY — 15–20 minutes. Disconnect power before servicing. Open the dryer door and remove the front panel or lint screen housing to access the door switch. Disconnect the wire harness, unclip or unscrew the old switch, install the new WP3406105 switch, reconnect the harness, and reassemble. Test door-start function before closing up.

Some older Whirlpool-built dryers used a two-wire door switch — the updated three-wire assembly is compatible as a replacement, but the extra wire (used for a drum light on equipped models) will remain unused on non-light models. Confirm your connector matches before ordering, or send us your model number and we’ll verify fitment. ✓ Model-Specific Repair Pages Whirlpool 11061252010 Dryer Parts & Repair Guide Whirlpool 11060887990 Dryer Parts & Repair Guide Whirlpool 11060884990 Dryer Parts & Repair Guide Whirlpool 11060882990 Dryer Parts & Repair Guide Whirlpool 11060857990 Dryer Parts & Repair Guide Whirlpool 11060854990 Dryer Parts & Repair Guide Whirlpool 11060852990 Dryer Parts & Repair Guide Whirlpool 11060842990 Dryer Parts & Repair Guide Whirlpool 11060832990 Dryer Parts & Repair Guide Whirlpool 1106072011 Dryer Parts & Repair Guide Whirlpool 1106072010 Dryer Parts & Repair Guide Whirlpool 1106062110 Dryer Parts & Repair Guide Whirlpool 11060232002 Dryer Parts & Repair Guide Whirlpool 11060232001 Dryer Parts & Repair Guide Whirlpool 11060232000 Dryer Parts & Repair Guide Whirlpool 11060212990 Dryer Parts & Repair Guide Whirlpool 11060202990 Dryer Parts & Repair Guide Whirlpool 11060172002 Dryer Parts & Repair Guide Whirlpool 11060172001 Dryer Parts & Repair Guide Whirlpool 11060172000 Dryer Parts & Repair Guide Whirlpool 11060022011 Dryer Parts & Repair Guide Whirlpool 11060022010 Dryer Parts & Repair Guide Whirlpool 11060012002 Dryer Parts & Repair Guide Whirlpool 11060012001 Dryer Parts & Repair Guide Whirlpool 11060012000 Dryer Parts & Repair Guide
