GE Gas Range Burner Won’t Light? WB21K10031 Gas Valve Assembly — Fix No-Ignition Fast
When a burner on your GE gas range won’t ignite, produces a weak or uneven flame, or cuts out immediately after lighting, a failed gas valve assembly is the most common cause. In JCGB660 and JCGB700 series GE gas ranges, the gas valve assembly controls gas flow to each surface burner. When the valve solenoid fails or the valve body cracks, gas flow is interrupted and the burner won’t light or won’t stay lit. ⚡ Common failure point in GE gas ranges after repeated heat cycling. Part WB21K10031 is the genuine OEM natural gas valve assembly (9100B series, -140° rated) that restores safe, reliable gas flow and full burner operation.
❓ Is This the Right Part?
This is the correct fix if ALL of the following are true:
- ✔ Range powers on and oven function works normally
- ✔ Gas supply to the range is confirmed on at the shutoff valve
- ✔ Igniter sparks when the burner knob is turned — ignition system is working
- ✔ Gas supply pressure has been confirmed adequate at the meter
- ✔ ONLY problem is one or more burners not receiving gas or flame cutting out immediately

🔧 Common Symptoms
- Burner clicks repeatedly but will not ignite — most common complaint
- No gas flow to one or more surface burners
- Weak, uneven, or flickering flame at the burner
- Burner ignites momentarily then flame cuts out immediately
- Gas odour near the range without visible flame — shut off gas and ventilate immediately
- One burner works normally while adjacent burners fail — valve-specific failure
✔ If these symptoms match, this is the most likely failed component in the system.
✔ In most cases, replacing the gas valve assembly restores full burner operation immediately.

⚠️ Recommended While Repairing:
Inspect the burner igniter while the valve is out — a failing igniter is frequently the root cause of valve stress and often fails alongside the valve after repeated heat cycling. If the igniter shows cracks, carbon buildup, or is more than 5 years old, replace it at the same visit to prevent a repeat no-ignition call.

⚙️ Installation
Skill Level: ADVANCED — 45–60 minutes. Shut off the gas supply at the shutoff valve and disconnect power before beginning — this is a gas line repair. Remove the cooktop or range top panel to access the valve manifold, disconnect the gas line fitting and wiring harness, and swap the valve. Reconnect all fittings and test every connection with approved leak-detection solution before restoring gas and power. Never use an open flame to check for leaks.
💡 Pro Tip
Always Leak-Test Every Connection After a Gas Valve Repair:
Apply approved gas leak detection solution (or soapy water) to every fitting you touched — valve inlet, outlet, and any unions — before restoring gas flow. Bubbles indicate a leak that must be corrected before the range is used. This step takes 2 minutes and is non-negotiable on any gas appliance repair.
