WB16T10046 GE Oven Gas Cooktop Large Burner 12000 Btus is a replacement large burner assembly designed for GE gas cooktops and ranges,rated to deliver approximately 12,000 British Thermal Units (BTUs) of heat under standard operating pressure. As a burner component, it typically comprises the burner ring (with ports), burner cap, burner bowl or mounting flange, and the orifice that meters fuel; the assembly may be configured for natural gas or, with the correct orifice, for propane (LP) service.
Within the appliance, this burner is the primary heat source for one of the high-output cooking zones and interfaces directly with the gas manifold and control valve to receive metered fuel. It also interacts with the ignition system (spark igniter or pilot), the air shutter/venturi that controls primary air for the air-fuel mix, the cooktop grate and support structure, and any flame sensing or safety interlocks present on the range. The burner’s physical design and orifice size determine flame pattern, heat distribution, combustion efficiency, and responsiveness to control knob inputs, so correct installation and compatibility with the appliance’s pressure/regulator settings are important for safe, efficient operation.
In this article readers will find a technical overview of the burner’s function and construction, guidance on compatibility and identification (including BTU rating and orifice considerations), common failure symptoms to watch for (for example weak or uneven flame, yellow/sooty combustion, delayed ignition, or gas odor), and diagnostic approaches a technician can use to isolate the issue. The article will also cover replacement considerations such as matching OEM specifications (mounting, orifice size, and gas type), conversion requirements, required hardware and sealing interfaces, and criteria for when qualified service is advisable versus simple cleaning or minor adjustments.

Function and Role of the Cooktop Large Burner Assembly in GE Gas Ovens
The WB16T10046 GE Oven Gas Cooktop Large Burner 12000 btus serves as the primary high‑output burner assembly for the cooktop’s largest cooking position, converting regulated gas flow into a controlled heat source. The assembly couples a properly sized orifice with a venturi air mixer and a machined burner head so gas and primary air mix before issuing through the ring of ports beneath the burner cap; the resulting flame pattern and heat flux are functions of orifice diameter, air shutter setting, manifold pressure, and unobstructed port geometry.
Functionally, the large burner provides higher convective and conductive heat transfer to pans and is intended to operate with the range’s manifold, ignition module, and mounting bracket as a matched system; mechanical fit and gas type must be confirmed against the appliance model when replacing the part. Typical service issues that affect performance include clogged ports, corroded or warped burner caps, misalignment, and orifice blockage-symptoms are uneven flame distribution, yellow tipping, soot buildup, or delayed ignition-and remediation ranges from port cleaning and cap seating adjustment to full replacement of the assembly when structural damage compromises flame stability or safety.
- Design feature: matched orifice and port pattern for a nominal high output.
- Compatibility note: intended for specific GE cooktop models-verify appliance model before ordering.
- Common symptoms of failure: uneven flame,yellow tips,soot,delayed ignition.
- Maintenance actions: clear port obstructions, inspect burner cap seating, confirm orifice integrity and manifold pressure.

How the WB16T10046 GE Oven Gas Cooktop Large Burner 12000 Btus Works Inside the Appliance
WB16T10046 GE Oven Gas Cooktop Large Burner 12000 btus is a burner assembly that converts regulated gas flow into a distributed ring of combustible mixture to produce up to 12,000 BTU of thermal power. Internally the component consists of an orifice/jet sized for the rated input, a burner tube with precisely located ports, a burner cap and crown that shape the flame, and interfaces for the cooktop valve and spark igniter or pilot. Gas delivered from the manifold passes through the orifice where pressure drop creates a controlled flow; primary air is drawn through an adjustable air shutter so the gas-air mixture exits the ports and ignites. The geometry of the ports and cap determines flame distribution and heat flux across cookware, so replacing this part requires matching orifice size and port pattern to the appliance’s gas type (natural vs. LP) and manifold pressure to maintain the intended 12,000 BTU performance and safe combustion characteristics.
Functionally and in service, the burner behaves as a precision flow-and-mixing device: improper orifice, damaged ports, or blocked passages produce uneven flame rings, yellow tipping, or reduced heat output. Compatibility considerations include valve outlet dimensions, igniter position, and the appliance’s control linkage; a technician replacing the unit should verify manifold pressure, confirm the orifice designation for the fuel type, and adjust the air shutter untill a short, blue “knife-edge” flame is observed across all ports. Practical diagnostics include visual flame inspection, leak testing at joints after installation, and verifying output by timing a known water boil under controlled conditions. Typical failure modes are corrosion of the burner ports, misalignment after reassembly, and carbon buildup; addressing these restores consistent 12,000 BTU operation and expected cooktop behavior.
- Normal flame: even blue ring with minimal yellow tipping
- Common faults: clogged ports, wrong orifice for LP/Natural gas, loose burner cap
- Installation checks: manifold pressure, leak test, igniter alignment
- Performance context: suited for high-heat searing and rapid boiling when installed and tuned correctly

Common Failure Symptoms and Diagnostic Indicators for the Large Burner
The WB16T10046 GE Oven Gas Cooktop Large Burner 12000 Btus is a primary heat source intended to deliver a nominal 12,000 Btu output under standard manifold pressure and proper orifice sizing.Functionally, the large burner assembly must produce a steady, evenly distributed blue flame across the burner ports; deviations from that behavior indicate either combustion-air imbalance, obstructed ports, or incorrect orifice/pressure.Compatibility considerations include matching the orifice size and manifold pressure of the host appliance-installing a burner rated for a different pressure or using the wrong orifice will change heat output and flame characteristics. In practical servicing, technicians examine the burner cap seating, port cleanliness, and orifice alignment before replacing the assembly to avoid needless component swaps.
Diagnostic indicators for failure are primarily visual and functional: incomplete ignition, persistent sparking, yellow tipping, or flame lifting each point to distinct root causes that can be verified with simple tests. Start with a visual inspection and a continuity check of the spark electrode and wiring, then observe flame color and stability while noting any odor of unburned gas; use a handheld manometer or the appliance’s service ports to confirm manifold pressure when flame appearance is ambiguous. Such as, a weak, lazy flame that improves when the cap is reseated usually means port blockage or a misaligned burner cap, whereas repeated sparking after ignition more often implicates a wet or damaged electrode or a faulty flame detection circuit.
- Continuous clicking but no ignition – possible faulty igniter,electrode misalignment,or moisture on the electrode.
- Yellow or sooty flame - restricted primary air, dirty ports, or incorrect orifice-to-pressure matching.
- Uneven flame pattern – clogged ports or a warped burner head; inspect and clean before replacement.
- Strong gas odor with slow ignition – check valve sealing, line connections, and spill-over from slow pilot delay.
| Item | Description |
|---|---|
| Flame appearance | Steady blue flame with a defined inner cone; yellow tips indicate air-fuel imbalance or contamination. |
| Ignition behavior | Single spark to steady flame is normal; persistent sparking or delayed ignition suggests electrode or valve issues. |
| Rated output | 12000 Btus nominal – lower measured heat typically means restricted flow or incorrect orifice/manifold configuration. |
Compatibility, Replacement Considerations, Installation Procedures, and Troubleshooting for the WB16T10046 Large Burner
The WB16T10046 GE Oven Gas Cooktop Large Burner 12000 Btus is a direct-replacement burner assembly designed to reproduce the original combustion geometry and heat output of specific GE cooktop models. Compatibility depends on matching the burner-to-orifice relationship, mounting tabs, and igniter-electrode location rather than just overall diameter; a visually similar burner can produce different flame characteristics if the orifice size, manifold pressure, or primary air shutters differ. Such as, installing a 12000 Btu burner in a circuit originally set for a lower-Btu burner will change gas flow and may require verification of regulator settings or an orifice change if the appliance supports LP conversion. Technicians should cross-reference the appliance model and service manual, confirm gas type (natural or LP), and inspect mounting clips and the electrode clearance before assuming interchangeability.
Before beginning work, shut off gas and power and verify absence of residual pressure.Remove grates and burner caps, disconnect the igniter lead, and lift the old burner out of its mounting; clean contact surfaces and check the orifice for debris prior to installing the WB16T10046. After reassembly, perform a soap-leak test at fittings, then observe flame pattern - a correct installation yields a stable, predominantly blue cone with minimal yellow tipping and uniform port ignition. common troubleshooting cues and likely corrective actions include:
- Yellow tips or sooting – check primary air shutter adjustment, contaminated ports, or incorrect gas type/orifice.
- Uneven or intermittent ignition - verify burner cap seating, electrode gap and alignment, and clean burner ports.
- High flame or poor simmer control – confirm orifice size and regulator/manifold pressure are correct for 12000 btu output.
- Igniter continuous clicking - dry or loose electrode connections, or a wet/contaminated igniter surface.

Q&A
What is the WB16T10046?
The WB16T10046 is an OEM replacement large surface burner head for GE gas cooktops and ranges. It is rated at about 12,000 BTU and is used as the high-output (large) burner on compatible GE models. It replaces the metal burner cap/hood assembly that distributes the gas to the burner ports.
How can I confirm this part fits my GE range or cooktop?
Confirm fitment by matching the exact GE part number (WB16T10046) to the part listed for your appliance model. Find your appliance model number on the rating plate (often inside the oven door frame, behind the storage drawer, or on the back of the unit) and check the GE parts website or an authorized parts dealer. Also compare the physical shape, mounting style and orifice position to the old burner to ensure it will seat correctly.
What are the basic steps to replace the large burner with WB16T10046?
General replacement steps: 1) Turn off the gas supply and disconnect power to the range. 2) Remove the grate and burner cap.3) Lift off the old burner head (it usually lifts straight off or is held with a single screw/nut-refer to your model’s service manual).4) Clean the area around the orifice and ports. 5) Install the new WB16T10046, making sure it seats squarely over the orifice and any locating tabs. 6) Reinstall the cap and grate, restore gas and power, and test ignition. If the burner attaches differently on your model, follow the appliance service manual. If you smell gas at any time, stop and ventilate-do not ignite and call a professional.
My new burner has a yellow or lifting, sooty flame. What does that mean and how do I fix it?
A yellow or sooty flame indicates incomplete combustion. common causes are clogged ports, grease buildup, the wrong orifice (wrong gas type or size), or incorrect air mixture (air shutter position). First, remove and clean the burner ports thoroughly.Confirm the burner and orifice are for the correct fuel type (natural gas vs. LP). If cleaning and correct orifice don’t fix it, have a qualified technician check gas pressure and air shutter adjustment or perform an LP/NG conversion if required.
How can I tell if the WB16T10046 is defective or if the problem is elsewhere?
Because the burner head is a passive metal component, defects are usually physical (blocked or damaged ports, warped seating surface). Symptoms that point to the burner head: uneven flame pattern confined to that burner, visible blockages or damage to the ports. To isolate the problem, swap the suspect burner with another identical burner location (if available).If the problem follows the burner, it’s the part; if it stays at the original location, the issue is the valve, orifice, igniter, or gas delivery. If ignition sparks but no flame appears,check the gas valve and orifice; if there’s gas smell but no ignition,stop and call service.
What tools and safety precautions do I need to replace this burner?
Common tools: flat or Phillips screwdriver, small nut driver or wrench (if applicable), soft brush/toothbrush for cleaning, and safety gloves. Safety: turn off the appliance power and gas supply before starting, ventilate the area if there’s any gas smell, avoid open flames while working, and do not overtighten fasteners. If you are uncomfortable working on gas components, hire a qualified appliance technician.
How should I clean and maintain the WB16T10046 to prevent problems?
Regular maintenance: remove the grate and burner cap, lift off the burner head and soak in warm, soapy water if greasy, then scrub ports gently with a soft brush. Avoid using wire to poke out ports aggressively-use a thin,soft tool only if necessary and be careful not to enlarge ports. Dry completely before reassembly. Wipe up spills promptly and avoid letting sugary spills bake onto the burner. Periodic cleaning prevents clogged ports and poor combustion.
Where should I buy the WB16T10046 and what about warranty or replacements?
Buy OEM WB16T10046 burners from GE authorized parts dealers, the GE Appliance Parts website, or reputable appliance parts suppliers to ensure authenticity and warranty coverage. Aftermarket sellers may sell compatible copies but check return policies and warranties. Keep your purchase receipt and part number; many OEM parts carry a limited warranty-contact the seller or GE customer service for details. If in doubt about fit or installation, consult a certified technician.
