GE Range Range Parts WB21K10031, Replaces 9100B Gas Burner Won't Light Gas Valve Assembly OEM Replacement
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.

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.
