GE Range Burner Not Heating or Stuck on High? Infinite Switch WG02F05778 – Fix Burner Control Failure Fast

A failed infinite switch is the most common cause of a GE electric range burner that won’t heat, stays stuck on high, or loses all temperature control. In GE, Hotpoint, and Kenmore electric ranges, the infinite switch (also called a surface burner switch or simmerstat) sits behind the control knob and regulates power to the burner element by cycling on and off at varying rates — the higher the knob setting, the longer the element stays on between cycles. When the internal bi-metal contacts weld shut, burn out, or fail open, the burner loses all control — going full-on, full-off, or becoming completely unresponsive regardless of knob position. ⚡ Common failure point in GE JB-series electric ranges — infinite switches wear from thermal cycling and contact arcing over time. Part WG02F05778 is the genuine OEM replacement that restores precise burner temperature control immediately — direct supersession of WB24T10148 and WB24T10162, 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 or the oven function normally
• ✔ The burner element itself tests OK on a multimeter — not open circuit
• ✔ Control knob is intact and seated correctly on the switch shaft
• ✔ ONLY problem is this specific burner won’t heat, is stuck on high, or doesn’t respond to the knob

🔧 Common Symptoms

• Burner won’t heat on any setting — most common complaint
• Burner stuck on high — won’t turn down or off via the knob
• Burner only works on some settings — dead zones in the knob range
• Intermittent heating — burner cycles on and off erratically
• Burning smell or visible scorching around the switch body
• Burner indicator light doesn’t illuminate when burner is on

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

✔ In most cases, replacing WG02F05778 restores full burner temperature control immediately.

📦 Part Details

⚙️ Installation

Skill Level: MODERATE — 30–45 minutes. Disconnect power at the breaker before beginning — switch terminals carry 240V. Remove the control knob and unscrew the control panel to access the switch from behind. Photograph all spade terminal connections before disconnecting — each terminal position controls a specific circuit. Transfer terminals one at a time from the old switch to the new WG02F05778, reinstall the panel and knob, restore power, and test all heat settings before returning to service.
