GE Range Burner Won’t Heat or Stuck on High? Infinite Switch WS01F09340 – Fix Burner Control Fast

A GE or Mabe electric range burner that won’t heat at any setting, stays stuck on high, or only works at one temperature has a failed infinite switch — the component that controls burner power from simmer to full heat. In most GE DER, JCAS, REX, and RAS series electric ranges, the infinite switch WS01F09340 regulates the duty cycle of the surface burner element, cycling it on and off to maintain the selected temperature. When it fails, the burner either loses all heat, stays on full power regardless of the knob position, or becomes erratic. ⚡ One of the most common surface burner failures on GE and Mabe-built electric range platforms. Part WS01F09340 is the genuine OEM infinite switch (Item #67 in diagram) that restores precise burner temperature control across all settings.

❓ Is This the Right Part?

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

• ✔ Your range powers on and the oven and other burners function normally
• ✔ The burner element itself is intact — no visible breaks, cracks, or burn marks on the coil
• ✔ The burner receptacle block is undamaged and making good contact with the element
• ✔ The control knob is not stripped — it turns the switch shaft correctly
• ✔ ONLY problem is one burner won’t heat, stays on high, or has no temperature control

🔧 Common Symptoms

• Surface burner won’t heat at any setting — most common search: “GE range burner not working”
• Burner stays on full heat regardless of knob position — won’t simmer
• Burner only works on high — no response to lower settings
• Burner cycles on and off erratically — temperature won’t hold
• Burning smell or visible scorching around the switch area behind the control panel
• Knob turns freely but burner doesn’t respond — switch shaft not engaging

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

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

⚙️ Installation Notes

Skill Level: Moderate — 20–30 minutes. Disconnect power at the breaker before beginning — the infinite switch carries 240V line voltage. Remove the control panel screws and tilt or pull the panel away from the range to access the switch from behind. Photograph all wire terminal positions before disconnecting — incorrect terminal reassignment will cause the burner to malfunction. Transfer wires one at a time to the new WS01F09340, secure the switch in the panel, reassemble, restore power, and test all heat settings from low to high.
