Fan Speed Switch WP4456836 – Fix It Fast When your range's downdraft fan runs at only one speed — or won't respond to the speed selector at all — the fan speed switch has failed. In most Whirlpool-built downdraft ranges, the speed switch is the single point of control between the user and the blower motor. When it fails, the fan may run at full blast constantly, refuse to change speeds, or stop responding entirely — leaving smoke and grease with nowhere to go. ⚡ Common failure point in Whirlpool, KitchenAid, Maytag, and Jenn-Air downdraft ranges. Part WP4456836 is the genuine OEM replacement that restores full multi-speed fan control and proper ventilation performance. ❓ Is This the Right Part? This is the correct fix if ALL of the following are true: ✔ Your range powers on and cooks normally ✔ The downdraft blower motor runs (fan spins) ✔ Wiring and connections to the switch are intact ✔ ONLY problem is the fan won't change speeds or doesn't respond to the speed selector Not sure? Send us your model number — we'll confirm before you order. 🔧 Common Symptoms Downdraft fan runs at one speed only regardless of selector position Fan speed selector switch feels loose, broken, or unresponsive Fan won't turn on or off via the speed control Fan runs continuously at high speed with no way to reduce it Burning smell or arcing at the switch location ✔ If these symptoms match, this is the most likely failed component in the downdraft ventilation system. ✔ In most cases, replacing this fan speed switch restores full multi-speed operation immediately. 📦 Part Details Part Number: WP4456836 Type: Downdraft Fan Speed Switch — multi-position rotary selector Replaces: 4456836, AP6011812, PS11745018, EAP11745018 Brands: Whirlpool, KitchenAid, Maytag, Jenn-Air, Amana Condition: Genuine OEM — new in manufacturer packaging ⚠️ Recommended While Repairing: While the cooktop panel is open, inspect the downdraft blower motor for wear or reduced airflow. If the motor has been running at full speed due to a stuck switch, it may be near end of life. Replacing both at the same time saves a second labour call. ⚙️ Installation Skill Level: Moderate — 30 to 45 minutes. Disconnect power at the breaker before servicing. Remove the cooktop control panel to access the switch assembly, disconnect the wiring harness, and swap the switch. Reconnect, reassemble, and test all speed positions before closing up. ✓ Compatible Models Confirmed compatible with GS395LEGB0, GS395LEGB1, GS395LEGB2, GS395LEGB3, GS395LEGB4, GS395LEGB5, GS395LEGB6, GS395LEGB7, GS395LEGB8, GS395LEGQ0, GS395LEGQ1, GS395LEGQ2, GS395LEGQ3, GS395LEGQ4, GS395LEGQ5, GS395LEGQ6, GS395LEGQ7, GS395LEGQ8, GS395LEGS0, GS395LEGS1, GS395LEGS2, GS395LEGS3, GS395LEGS4, GS395LEGS5, GS395LEGS6, GS395LEGS7, GS395LEGS8, GS395LEGZ0, GS395LEGZ1, GS395LEGZ2, GS395LEGZ3, GS395LEGZ4, GS395LEGZ5, GS395LEGZ6, GS395LEGZ7, GS395LEGZ8 plus additional Whirlpool-platform downdraft models.

By the time the switch fails visibly, the motor bearings are frequently worn. Stocking WP4456836 alongside the compatible downdraft blower motor means you close the job in one visit instead of two.
