WB16T10046 GE Oven Gas Cooktop Large Burner 12000 btus is a replacement large surface burner assembly used on GE gas cooktops and range ovens; it is a rated 12,000 Btu burner head/orifice assembly designed too produce teh high-heat output for a primary cooking zone. As a hardware component, the assembly typically includes the burner head, ports, cap and mating orifice and is specified by Btu rating and port geometry to match the appliance’s gas supply characteristics and intended heat output.
Inside the appliance the WB16T10046 functions as the primary combustion device for a cooktop burner and directly interfaces with the gas manifold/orifice, the valve that meters gas flow, the igniter or pilot assembly that initiates combustion, and the surrounding burner hardware and grates that effect airflow. Its port size, spacing and material influence flame pattern, combustion efficiency and heat flux to cookware; it must thus be matched to the appliance’s manifold pressure and gas type (natural gas or LP) and works in conjunction with the regulator, safety valves and ignition system to provide safe, repeatable operation.
In this article readers will find a technical overview of the WB16T10046’s design and function, guidance on model compatibility and gas-type considerations, common failure symptoms to recognize (for example weak or yellow flames, uneven heating, delayed ignition or sooting), diagnostic points to inspect such as ports, orifice alignment and ignition components, and the practical replacement considerations that a technician or owner must evaluate (correct part number, mounting fit, gas-type conversion and sealing/leak considerations). The intent is to provide technical context to support troubleshooting decisions and correct part selection rather than step-by-step service procedures.

Functional Role and Thermal Performance parameters of the Cooktop Large Burner in GE Ranges
The WB16T10046 GE Oven Gas Cooktop Large Burner 12000 Btus serves as the high-output heating element on compatible GE cooktops, delivering a nominal 12,000 BTU thermal input through a ring of metered ports. Functionally this burner converts delivered gas flow and manifold pressure into a controlled flame pattern: inner and outer cones provide both rapid boil capability and a usable simmer range when paired with the proper burner cap and valve. Correct thermal performance depends on matching the burner to the range’s orifice size and gas type (natural vs. LP); using the OEM WB16T10046 in the intended configuration preserves designed heat flux, prevents rich combustion, and limits soot or yellowing caused by incorrect pressure or clogged ports.
- Nominal output: 12,000 BTU; performance varies with manifold pressure and orifice.
- Flame behavior indicators: steady blue cones, even ring illumination, and absence of yellow tips.
- Compatibility considerations: mounting footprint, port geometry, and gas type must match the appliance or conversion kit.
- Common faults: clogged ports, mis-seated cap, or wrong orifice leading to low heat, uneven flames, or noisy combustion.
technically, the burner’s thermal profile is defined by port size, spacing, and the gas supply rate; heat transfer to cookware is concentrated where the flame contacts the pot bottom and dissipates radially, so cookware diameter and placement materially affect effective output. In field service, verify performance by measuring flame pattern and temperature rise under a known load rather than relying solely on BTU rating: a calibrated gas pressure check, inspection of the burner cap seating, and a flame color/pattern sweep reveal whether the WB16T10046 is operating within expected parameters or if manifold/valve adjustments or cleaning are required. Replacement should follow OEM part matching to maintain control dynamics of the range’s valve and ignition system and to avoid altered simmer characteristics or safety interlock behavior.

How the WB16T10046 GE Oven Gas Cooktop Large Burner 12000 Btus integrates with Orifice, Valve and Ignition Subsystems
The WB16T10046 GE Oven Gas Cooktop Large Burner 12000 Btus functions as the gas-to-heat conversion element at the end of a system that includes a manifold valve, a calibrated orifice, and an ignition source. Gas from the appliance valve is metered through the orifice, which sets the volumetric flow for the 12,000 BTU capacity, then exits through the burner ports where the ignition subsystem provides a spark or pilot to initiate combustion. The effective flame shape and thermal output depend on the matched relationship between orifice diameter and manifold pressure – a change in either will alter flow rate, flame length, and combustion stability. Installing this burner without verifying orifice size and valve compatibility can produce weak or lifting flames, incomplete combustion (yellow tipping), or cause the safety controls to shut down the gas supply.
- Key interfaces: orifice seating and diameter, valve outlet coupling, igniter electrode position and wiring harness.
- Common service checks: verify orifice and seat alignment, measure spark gap/position, inspect port cleanliness and valve closure.
- Practical adjustment: at higher elevation reduce flow via smaller orifice or regulator adjustment rather than relying on the burner alone.
| Item | Description |
|---|---|
| Rated input | 12,000 BTU - determines maximum gas flow requirement when matched to orifice and valve |
| Orifice | Calibrated aperture that establishes flow at a given manifold pressure; must match valve/regulator settings |
| Valve interface | Mechanical coupling and pressure drop characteristics of the manifold valve control flow modulation and shutoff |
| Ignition interface | Spark electrode location and wiring; correct gap and proximity to ports ensure reliable ignition and cross-lighting |
In service contexts technicians should treat the burner,orifice and valve as a tuned subassembly: confirm that the valve provides expected manifold pressure,replace orifice sizes only with approved equivalents,and position the igniter electrode to the manufacturer’s recommended clearance for consistent ignition. Diagnostic examples include observing long, lifting flames (suggests excessive flow or high pressure), persistent yellow tips (indicates poor primary air or partial blockage of ports), and repeated ignition attempts (electrode gap/misalignment or weak spark). When replacing the WB16T10046 or its neighboring components, document part numbers, test flame behavior under normal manifold pressure, and clean or replace clogged ports to restore intended performance.
Common Failure Symptoms: Flame Pattern Irregularities, Reduced Heat Output, Gas Odor and Ignition Failures
The WB16T10046 GE Oven Gas Cooktop Large Burner 12000 Btus typically produces a stable, blue inner cone with a lighter blue outer envelope; deviations from that pattern indicate specific mechanical or fuel-delivery faults rather than cosmetic issues.Yellow tipping, soot buildup, or a lifted/flapping flame frequently enough result from obstructed burner ports, incorrect air-to-fuel ratio (misadjusted air shutter orifice), or degraded burner caps that prevent even gas dispersion. Reduced heat output with the same control setting can point to restricted gas flow (partial obstruction in the burner orifice, regulator pressure loss, or a partially closed service valve), while ignition failures and repeated sparking with no flame are commonly caused by a fouled or misaligned electrode, melted or cracked ceramic insulation, or a non-seating gas valve downstream of the manifold. A detectable gas odor requires immediate attention as it signals a potential leak at a connection, flexible line, or regulator, which can coexist with or else normal burner operation.
- Yellow or sooty flame coloration – incomplete combustion,clogged ports
- Irregular,lifting,or flickering flame – air/fuel imbalance or damaged cap
- Low flame height or slow heat-up – restricted orifice,low manifold pressure
- No ignition or continuous sparking – faulty electrode/igniter or valve
- Gas odor – leak at connection,flexible hose,or regulator
Practical troubleshooting begins with visual and simple mechanical checks: remove and inspect the burner cap and base for carbon deposits,clear ports with a soft brush or compressed air,and confirm correct seating and orientation of the burner cap; measure electrode gap and alignment with a small feeler gauge and dry the area if moisture is present. For performance issues beyond basic cleaning, verify manifold pressure and inspect the regulator and service valves for partial closures or leaks; a technician will use a manometer or gas pressure gauge to compare measured pressure against the appliance specification. If a gas odor is present, shut off the gas supply, ventilate the area, avoid operating electrical switches or ignition sources, and contact a qualified service technician-do not attempt internal regulator or valve repairs unless certified to service gas appliances. The WB16T10046 is compatible with GE cooktops designed for a 12,000 BTU large burner, so replacement must match the same orifice size and mounting geometry to maintain intended combustion characteristics and safe operation.
| Item | Description |
|---|---|
| Yellow/sooty flame | Clogged ports or incorrect air shutter – clean ports, verify air shutter position |
| Low heat output | Restricted orifice or low manifold pressure – inspect orifice, check regulator pressure |
| Ignition failure | Fouled/misaligned electrode or faulty valve - inspect electrode gap, test valve continuity |
| Gas odor | Leak at connection or regulator – shut off gas and arrange qualified repair |
Replacement Considerations and Step‑by‑Step Installation Procedures for the Cooktop Large Burner Assembly
The WB16T10046 GE Oven Gas Cooktop Large Burner 12000 Btus is the primary high‑output burner assembly used on compatible GE gas cooktops; it provides a concentrated flame pattern designed for high heat tasks and must match the cooktop’s orifice and regulator settings to perform correctly.Functionally, the assembly includes the burner head, cap, burner base, and the ignition electrode; correct seating of the cap and precise electrode alignment determine flame stability and ignition reliability.In practice, technicians replace this part when a cracked burner head causes uneven combustion, when sustained yellow tipping indicates air‑fuel imbalance, or when physical damage prevents a proper seal between the burner cap and base. Compatibility checks should include gas type (natural vs. LP), model cross‑reference, and verification that the replacement unit shares the cooktop’s mounting geometry and electrode position to avoid flashing or delayed ignition.
- Pre‑work: Shut off the gas supply and electrical power to the appliance; remove grates, burner caps, and control knobs to access the cooktop surface.
- Lift or remove the cooktop panel per model instructions and disconnect any wire harnesses that obstruct access to the burner assembly.
- Remove the retaining screw(s) or clips holding the large burner base, lift out the old assembly, and inspect the orifice and ignition electrode for damage or contamination.
- Install the WB16T10046 assembly ensuring the burner base seats flat, the cap sits concentric, and the electrode tip is positioned ~2-3 mm (about 1/8″) from the burner rim; secure fasteners snugly without over‑torquing.
- Reassemble the cooktop, restore gas and power, perform a soap solution leak check at the gas connection, then light the burner and confirm a steady, blue flame and reliable ignition.
During installation, verify orifice and regulator settings match the cooktop’s certified configuration; using the wrong orifice size or failing to convert between LP and natural gas will produce incorrect flame shape and heat output. After fitting the part, document the tests performed: ignition cycles, flame appearance under low and high settings, and a gas leak check at the valve and connection points. If the burner exhibits persistent yellow tipping, noisy combustion, or slow ignition after replacement, recheck cap seating, electrode gap, and the cleanliness of the orifice; replace the orifice or clean using manufacturer‑approved methods only. The table below summarizes key technical references to confirm during replacement.

Q&A
What exactly is the WB16T10046 and is it really a 12,000 BTU burner?
WB16T10046 is the GE replacement large burner head assembly for certain GE gas cooktops. The burner is commonly rated at about 12,000 BTU input (this is the maximum input rating published for the large burner). Always confirm the rating on your appliance data plate or the part listing for your specific cooktop model to be certain.
How do I replace the WB16T10046 large burner on my cooktop?
General replacement steps: shut off the gas supply and power to the appliance, remove grates and burner caps, lift off the burner head, disconnect any retaining screws or clips, fit the new burner head in the same orientation, reattach screws/clips, replace the cap and grates, restore gas and power and test for proper ignition and flame pattern. Because work on gas fittings can be hazardous, any task that requires shutting off or reconnecting the gas line or regulator should be performed or checked by a qualified gas technician.
How can I tell if the WB16T10046 will fit my GE cooktop model?
Match the OEM part number (WB16T10046) to the list of compatible model numbers in the part-supplier cross-reference or your cooktop’s parts diagram. You can also compare the physical shape and mounting points of the existing burner. If in doubt,provide your cooktop model number to a GE parts dealer or authorized service technician to verify fit and compatibility before ordering.
My large burner clicks but won’t light – what should I check?
Common causes: no gas supply (pilot or main gas valve off), clogged orifice/ports, wet or dirty igniter electrode, electrode gap or position out of alignment, or a failed gas valve/ignition module. Troubleshooting: verify other burners get gas, dry and clean the burner ports and igniter area, ensure the electrode is intact and correctly positioned, and observe whether a strong visible spark appears at the electrode when you try to light. If gas is present but there’s no spark, the igniter or its wiring may be faulty; if there is spark but no flame, suspect the gas supply or orifice.For safety, contact a qualified technician if you cannot isolate the problem.
Why is the burner flame yellow or sooty instead of blue?
A yellow, lazy or sooty flame indicates incomplete combustion. Common causes are clogged or partially blocked burner ports, debris on the burner head, incorrect air-to-gas mixture (air shutter misadjusted), wrong orifice for the gas type, or improper gas pressure. Start by cleaning the burner ports and head. If the problem persists, stop using the burner and have a qualified service technician check the orifice, air shutter adjustment and gas pressure-continued operation with incomplete combustion can produce carbon monoxide and is a safety hazard.
The burner flame is too low or won’t reach full power – what could cause that?
low flame can be caused by a clogged orifice/ports, partially closed valve, a faulty regulator, incorrect conversion orifices (if the unit was converted between natural gas and LP), or inadequate supply pressure. Clean the ports, confirm the burner cap and head are properly seated, and check other burners to see if they also run low (which points to supply/regulator issues). Gas pressure or regulator adjustment should be handled by a qualified technician.
Can I convert this WB16T10046 burner between natural gas and LP (propane)?
Many GE cooktops are convertible, but conversion requires the correct OEM conversion kit (orifices and sometimes a regulator adjustment) and must be performed according to the manufacturer’s instructions. Conversion should be done by a qualified service technician to ensure safe, proper orifice installation and gas pressure settings. Never attempt to run a burner on the wrong gas type without the proper conversion parts and professional adjustment.
What is the recommended cleaning and maintenance for the large burner head?
Routine maintenance: allow the cooktop to cool, remove grates and burner caps, lift off the burner head, and clean ports with a soft brush or compressed air. Use mild dish soap and a non-abrasive cloth for the burner head and caps; avoid wire brushes or sharp tools that can widen the ports. Make sure all parts are entirely dry and reassemble carefully so the igniter electrode and ports are correctly aligned. Wipe spills promptly and avoid using oven cleaner or harsh chemicals on burner components. If ports are severely distorted or damaged, replace the burner assembly (WB16T10046) rather than trying to repair it.
