Range Burner Not Heating or Stuck On? Infinite Switch W11730306 — Fix Burner Control Failures Fast

A burner that won’t heat, won’t turn off, or only works on one heat setting is almost always a failed infinite switch — not a wiring or element problem. In most Whirlpool electric ranges, the infinite switch is the rotary control that regulates power to the surface burner element by cycling it on and off at varying rates. When it fails, the burner may stay cold at all settings, run at full heat regardless of the dial position, or only work at one fixed temperature. ⚡ One of the most common surface burner failures on Whirlpool-platform electric ranges. Part W11730306 is the genuine OEM replacement infinite switch that restores full variable heat control to the affected burner.

❓ Is This the Right Part?

This is the correct fix if ALL of the following are true:

• ✔ Range powers on — clock, oven, and other burners work normally
• ✔ The burner element itself has been tested and confirmed functional
• ✔ The burner receptacle and wiring connections are intact
• ✔ ONLY problem is the affected burner not responding correctly to the control dial

🔧 Common Symptoms

• Burner doesn’t heat at any dial setting
• Burner runs at full heat regardless of dial position
• Burner only works on one heat level — no variable control
• Burner cycles on and off erratically or inconsistently
• Burning smell or visible scorching around the switch body
• Dial turns freely but produces no change in burner output

✔ If these symptoms match, this is the most likely failed component in the surface burner circuit.

✔ In most cases, replacing this infinite switch restores full variable heat control immediately.

⚙️ Installation

Skill Level: Moderate — 30–45 minutes. Disconnect power before servicing. Remove the control knob and unscrew the control panel to access the switch. Photograph the existing wiring before disconnecting — infinite switches have multiple terminals and incorrect wiring will cause the burner to malfunction. Transfer wires one at a time to the new switch, reinstall the panel, and test all heat settings before reassembling fully.
