LG Range Burner Won’t Heat or Won’t Turn Off? Rotary Switch EBF62174904 – Fix Burner Control Fast

A burner that won’t heat, won’t turn off, or is stuck at one heat level points directly to a failed rotary infinite switch. In most LG electric ranges, the rotary switch controls the power cycling to each surface burner element — when it fails, the burner loses all heat control. ⚡ Common failure point in LG and Kenmore Elite electric ranges. Part EBF62174904 (now superseded by EBF62174907) is the OEM rotary switch that restores precise burner heat control — EBF62174907 is the current shipping replacement and is a direct drop-in fit.

❓ Is This the Right Part?

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

• ✔ Range powers on and oven functions work normally
• ✔ Other surface burners operate correctly
• ✔ Power supply to range is confirmed good (breaker, outlet)
• ✔ Burner element has been tested and is not open/failed
• ✔ ONLY problem is one burner won’t heat, won’t turn off, or is stuck at one level

🔧 Common Symptoms

• Burner cycles on and off erratically at any setting

⚙️ Installation Notes

Skill Level: Moderate — 20–30 minutes. Disconnect power at the breaker before beginning — this switch carries line voltage. Remove the control knob and unscrew the switch from the control panel; photograph the wire terminals before disconnecting. Transfer wires one at a time to the new switch matching terminal positions exactly. Incorrect wiring will cause the burner to run at full power continuously — double-check before restoring power.
