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 Part EBF62174904 (now superseded by EBF62174907) is the OEM rotary switch that restores precise burner heat control — EBF62174907 is the current shipping replacement and is a direct drop-in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
- Surface burner won’t heat at all — most common search symptom
- Burner stuck on high — won’t turn down or off
- Burner only works at one heat level regardless of knob position
- Knob turns but burner doesn’t respond
- Burner cycles on and off erratically at any setting
- Burning smell from control panel area when burner is in use
✔ If these symptoms match, this is the most likely failed component in the system.
✔ In most cases, replacing this rotary switch restores normal burner heat control immediately.

⚙️ 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.
💡 Pro Tip
💡 Pro Tip — Test the Burner Element Before Replacing the Switch:
A failed burner element produces identical symptoms to a bad infinite switch — no heat, intermittent heat, or one-level operation. Test the element for continuity with a multimeter before ordering the switch. If the element is open (no continuity), replace the element first — it’s typically a fraction of the cost and eliminates the most common misdiagnosis on LG electric ranges.
