Burner Won't Heat or Won't Shut Off – Fix Your LG Range Infinite Switch Fast

If a burner on your LG range won't heat up, stays on full blast, or won't turn off, the surface burner infinite switch is the most likely failed component. In most LG electric ranges, a failed rotary switch loses the ability to regulate current to the burner element — causing it to either stay cold or run uncontrolled. ⚡ Don't leave a runaway burner unattended — replace it today. Part EBF62174902 is the genuine OEM rotary switch (now shipped as superseded part EBF62174907) that restores precise burner control immediately.

❓ Is This the Right Part?

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

• ✔ You have an LG or LG Studio electric range (slide-in or freestanding)
• ✔ Your model number is in the confirmed compatibility list below
• ✔ One or more burners won't heat, won't turn off, or won't regulate temperature
• ✔ The burner element itself tests OK (element is not the failed part)
• ✔ ONLY problem is the burner control / infinite switch function

🔧 Common Symptoms

• Burner won't heat on any setting
• Burner stays on full heat regardless of knob position
• Burner won't turn off even when knob is at OFF
• Burner only works on one heat level (high or low only)
• Knob turns but burner doesn't respond
• Burning smell or visible scorch marks around switch area

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

✔ In most cases, replacing this infinite switch restores normal burner operation immediately.

⚙️ Installation Notes

Skill Level: Moderate — 30–60 minutes. Disconnect power at the breaker or unplug the range before beginning. Remove the control panel fascia, disconnect the wiring harness from the old switch (photograph connections first), unscrew the mounting bracket, and install the new switch in reverse order. Ensure all spade terminals are fully seated and the knob shaft engages correctly before restoring power. Do not overtighten mounting screws — snug only.
