GE Range Not Igniting or Controlling Gas Properly? GE Oven Range Control WS01F11566 — Fix Gas Burner Control Fast
A failed range control assembly is one of the most common causes of gas ignition and burner control problems in GE slide-in ranges. When the RC19 gas control assembly fails, the range may not ignite, burners may not respond to the control knobs, or the oven may fail to maintain temperature.
⚡ Common failure point in GE JCB840 and JCB870 series slide-in gas ranges.
Part WS01F11566 is the current GE OEM replacement for the RC19 gas control assembly, superseding WS01F11121 and 301D1494G020. This is the correct part to order for supported models.
❓ Is This the Right Part?
This is the correct fix if ALL of the following are true:
- ✔ Your range powers on and the display functions normally
- ✔ The gas supply to the range is confirmed on and at correct pressure
- ✔ Igniter spark or oven ignition is absent or erratic
- ✔ Your model number is JCB840DV1WW, JCB840ET1ES, JCB840ST1SS, or JCB870ST1SS

🔧 Common Symptoms
- Surface burners do not ignite or spark intermittently
- Oven burner fails to light or shuts off prematurely
- Burner control knobs do not respond correctly
- Range displays error codes related to gas control or ignition
✔ If these symptoms match, the RC19 gas control assembly is the most likely failed component.
✔ In most cases, replacing this assembly restores full ignition and burner control immediately.

Inspect the igniter electrodes and spark module while the range is open. A worn igniter or cracked electrode is a common co-failure with a control assembly fault — replacing both at the same service call avoids a repeat repair.
⚙️ Installation
Skill Level: Moderate — 30–60 minutes. Disconnect power and shut off the gas supply before servicing. Remove the control panel to access the RC19 assembly, disconnect the wiring harness, and transfer all connections to the replacement unit. Restore power and gas, then test all burners and oven ignition before reassembly.

💡 Pro Tip
GE has superseded WS01F11121 with WS01F11566. If your service manual or parts diagram still shows WS01F11121 or 301D1494G020, WS01F11566 is the correct current replacement. Do not order the old number — it is no longer available as a separate part.
