Frigidaire Range Burner Stuck on High, Won’t Heat, or Control Unresponsive? Infinite Dual Switch 140173679014 – Fix Burner Control Failures Fast

A failed infinite dual switch is the most common cause of a Frigidaire electric range burner that is stuck on one heat level, won’t turn on at all, or cycles erratically. In most Frigidaire electric ranges and cooktops, the infinite dual switch regulates the power delivered to the surface heating element — giving precise control from low simmer to high heat. When it fails, the burner loses the ability to modulate heat, leaving it stuck on high, completely dead, or cycling unpredictably. ⚡ Common failure point in Frigidaire electric ranges with heavy daily use. Part 140173679014 is the genuine OEM replacement that restores smooth, precise burner heat control immediately — no modification required.

❓ Is This the Right Part?

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

• ✔ Range powers on and other burners operate normally
• ✔ Element (coil or radiant) confirmed functional — not burned out
• ✔ Power supply and outlet confirmed delivering correct voltage
• ✔ Wiring harness to the switch confirmed intact with no burned terminals
• ✔ ONLY problem is one burner stuck on high, not heating, or control knob turns with no response

🔧 Common Symptoms

• Burner stuck on high heat and won’t turn down — most common customer complaint
• Burner not heating at all despite element being functional
• Control knob turns but burner does not respond
• Burner cycles on and off erratically at any setting
• Burning smell from the control panel area near the switch
• Visible burn marks or melted plastic on or around the switch body

✔ If these symptoms match, this is the most likely failed component in the system.

✔ In most cases, replacing this infinite dual switch restores full, precise burner control immediately.
