WB16K10070 GE Oven Gas Stove/Range Cooktop Small Burner Head is a serviceable burner head assembly intended for the small (simmer) burner on GE gas ranges and cooktops. As a metal component with an array of burner ports,it receives gas from the cooktop orifice and forms the distributed flame pattern at the burner surface; it is typically sized and shaped for lower BTU output compared with larger surface burners.
Within the appliance the small burner head mounts to the burner base and must align precisely with the gas orifice, spark electrode (or pilot/thermocouple where applicable), and the burner cap or grate. Its geometry and port condition control primary air mixing, flame shape, and heat distribution, so the head directly affects ignition reliability, combustion quality and low-heat simmer performance. The component thus interacts mechanically with the burner bezel and grate, pneumatically with the manifold/orifice and gas pressure, and electrically with the ignition/sensing system; corrosion, port blockage or warping can change flow characteristics and produce weak, yellow or unstable flames or ignition faults.
In the following article you will find a technical overview of the small burner head’s function and construction, guidance on verifying compatibility and model fit, common failure symptoms to recognize (such as weak flame, uneven heating, sustained clicking or yellow combustion), practical troubleshooting and cleaning procedures, and replacement considerations such as part verification, mounting orientation, electrode alignment and post‑installation leak and ignition checks. The facts is presented to help technicians, engineers and appliance owners diagnose problems and perform safe, correct repairs or replacements.

Function and Role of the Small Burner Head in GE Gas Stove and Range Cooktops
The WB16K10070 GE Oven Gas Stove/Range Cooktop Small Burner Head is the combustion component that shapes and stabilizes the flame for a cooktop’s small burner. It mounts to the burner valve stem and aligns a ring of gas ports so that the injected gas mixes with air at the correct ratio, producing a concentrated, low-power flame suited for simmering and delicate tasks. The geometry of the ports, the seating interface to the valve stem, and the fit with the burner cap directly affect flame quality-poor alignment or carbon buildup changes flow patterns, causing yellow tipping, sooting, or an inability to hold a low simmer.
- Primary features: radial port arrangement, seating interface for valve stem, corrosion-resistant material/finish.
- Operational behavior: produces a narrow, stable blue flame at low BTU settings; relies on correct orifice and manifold pressure for intended output.
- Compatibility notes: intended as an OEM replacement for identical head assemblies; verify model fit and gas type (natural gas vs LP) because orifice/pressure differences affect performance.
In practice, technicians check the small burner head when symptoms include uneven flame distribution, persistent yellow flame tips, gusting or lifting flames, or visible soot on cookware. Replacement steps are straightforward: remove the burner cap, lift off the worn head, confirm the valve stem and retaining hardware are undamaged, and install the new WB16K10070 in the same orientation before testing flame characteristics across low-to-high settings. For conversions or persistent combustion issues, confirm manifold pressure and orifice sizing rather than altering the burner head-changing orifices or regulator settings is the correct engineering approach to adapt between natural gas and propane systems.

How the WB16K10070 GE Oven Gas Stove/Range Cooktop Small Burner Head Works Inside the Appliance
The WB16K10070 GE Oven Gas Stove/range Cooktop Small Burner Head is the precision gas-dispensing component that sits beneath the burner cap and directs fuel to create the appliance’s small flame. Gas from the manifold passes through the orifice and into the burner head’s venturi and port ring; the geometry of those ports and the alignment with the burner cap determine flame size, shape, and stability. Within the appliance the burner head works in concert with the ignition electrode (spark or pilot), the safety valve, and the control valve: the ignition provides the ionizing spark, the safety system permits gas flow only when commanded, and the burner head converts that controlled flow into a distributed, low-power flame used for simmering or low-heat cooking. Technicians should match the burner head to the oven or cooktop model as port size and mounting features vary and directly affect air-gas mixture and BTU output.
Practical service tasks focus on maintaining correct port clearances, secure mounting, and proper alignment with the cap and electrode to avoid common issues such as unstable flames, yellow tipping, or slow ignition. Routine checks include inspecting for carbon buildup in the ports, verifying orifice seating and gasket condition, and confirming manifold pressure and valve operation when flame problems persist; replacing the WB16K10070 unit is appropriate when ports are eroded or mounting tabs are damaged. Common symptoms and diagnostic checks are summarized below to guide troubleshooting and parts selection.
- Uneven or elongated flame: inspect port blockages, cap seating, and electrode position.
- Yellow or sooting flame: check air shutter/venturi alignment and port condition.
- Weak flame or slow ignition: verify orifice size, manifold pressure, and valve function.

Common Failure Modes and Observable Diagnostic Symptoms of the Small Burner Head
The WB16K10070 GE Oven Gas Stove/Range Cooktop Small Burner Head controls gas distribution and establishes the burner’s primary flame pattern by directing manifold pressure through a ring of precision ports. Typical failure modes include port blockage from food residue or grease that alters jet geometry, corrosion or pitting that increases leakage or creates hot spots, mechanical deformation of the head or mounting tabs that misalign the air-fuel mix, and cracks in insulating or cast parts that change heat transfer. Compatibility is constrained to specific GE cooktop families and service schematics; a visually intact head can still fail functionally if the port diameters are eroded or distorted, so measuring flame characteristics is often necessary to determine whether cleaning, refurbishment, or replacement with a WB16K10070 unit is required.
Diagnostic symptoms are primarily observable in flame behavior, ignition response, and heat distribution; these symptoms guide a technician toward cleaning, adjustment, or component replacement. Start with a visual inspection for clogged ports, cracks, and warped surfaces, then assess flame color, height, and stability while noting any popping, lifting, or yellowing.If basic cleaning does not restore normal operation, check valve seating, manifold pressure, and igniter timing - cracked heads, broken locating tabs, or significant corrosion typically require replacement rather than repair. For clarity, common observable symptoms are listed below and a quick reference table maps symptoms to likely causes for field troubleshooting.
- Weak or uneven flame - usually caused by partially blocked ports or misaligned burner head.
- Yellow or sooty flame - indicates poor air/gas mixture from clogged ports or incorrect manifold pressure.
- Delayed ignition or continuous clicking – can result from gas leakage around the head or a mis-positioned igniter relative to the burner holes.
- Loud, roaring flame – suggests excessive primary air due to damaged air shutters or a warped head.
- Visible cracks,broken tabs,or severe corrosion – structural failures that necessitate replacement with the correct part number.
| Item | Description |
|---|---|
| Weak flame | Partial port obstruction or reduced manifold pressure; inspect and clean ports, verify pressure. |
| Yellow flame/sooting | insufficient primary air or oversupply of gas at the head; check port integrity and air shutters. |
| mechanical damage | Cracks, warped surfaces, or broken tabs alter alignment and require replacement (e.g., WB16K10070). |
Compatibility, Replacement Considerations and Installation Procedures for WB16K10070 and Equivalent Models
The WB16K10070 GE Oven Gas Stove/Range cooktop Small Burner Head is the flame-generation element for a range’s auxiliary burner; it mates to the valve orifice and shapes the jet stream so the ignition electrode and flame spreader deliver a stable, even flame. Compatibility hinges on the mechanical interface-outer diameter, center-post alignment, number and spacing of mounting tabs, and the seat face profile-as well as the correct orifice size for the appliance’s fuel (natural gas or liquid propane).Equivalent parts that match only visually can still produce problems: mismatched orifice alignment or a slightly different cap profile can cause uneven flames, delayed ignition, or contact with the igniter that wears the electrode prematurely.
Replacement and installation require planned verification and controlled steps. Before removing the defective head, confirm the orifice size and thread type, record electrode gap and position, and then shut off the gas supply and isolate electrical power to the igniter. During installation, seat the burner head squarely over the orifice, secure any retaining tabs or screws without over-torquing, reconnect ignition leads and recheck electrode clearance, then perform a leak test at the valve and observe flame color and stability under low and high settings; yellow flames or soot suggest an orifice or air shutter mismatch and may require converting the orifice or adjusting primary air. For example, converting a unit from natural gas to LP typically requires an appropriately sized LP orifice and verification that the burner cap vents and air shutters provide sufficient primary air to avoid sooting.
- Pre-install checklist: correct part number/dimensions, orifice size for gas type, intact electrode and gasket, appropriate tools and leak test solution
- Key post-install checks: electrode gap and position, leak test at fittings, stable blue flame across settings, secure mounting without distortion
| Item | Description |
|---|---|
| Mounting interface | Outer diameter, tab spacing, and center-post alignment must match valve orifice and cooktop recess |
| Orifice compatibility | Orifice ID and thread type for natural gas vs LP; conversion may be required |
| Ignition clearance | Electrode-to-cap distance and lateral position affect spark reliability and ignition timing |
