Function âand role of the WB16T10046 large burner within⢠GE gas cooktop systems
WB16T10046 GE âOven Gas âŁCooktop Large Burner â12000 Btus is the OEM large surfaceâ burner assembly used âon compatible GE gas âcooktops to deliverâ high heatâ for boiling, searing, âand ârapidâ water heating. âFunctionally, the â˘burner consistsâ of a stamped burner head with evenly âspaced ports, a sealed⢠cap that promotes even flame spread,â and an orifice that meters fuel per the manifold pressure;â togetherâ these elements produce the âŁrated 12000 Btu output when installed on a correctly configured manifold and⤠regulator.Techniciansâ should⣠expect stable, blue-stack flames across âthe port array when the âair shutter âand manifold pressure â¤are correct; yellow âtipping, sootor flickering typically â¤indicate blockedâ ports, incorrect âair-fuel mixtureorâ improper âorifice sizing for⤠the gas type â¤in use.
In a system context this⣠large burner acts as one of several⣠surface heat sourcesâ and must match the cooktop’s valve, â¤igniterand burner cap geometry to function âcorrectly â- the assembly is a mechanical and⤠fluidâ interface, not just a cosmetic part.When⢠replacing or âtroubleshooting⢠the âburner, verify seating of the burner cap, clear⢠port blockages with a soft tooland confirm orifice type for natural gas⢠versus LP conversion; conversion requires âthe correct â˘orifice and adjustment of the⢠regulator or manifold pressure.Practical examples: a front-right large burner⢠used for rapid pasta boilingâ should show full-height, steady flames under heavy âload, while uneven heating on âa pan often⣠traces back to a⢠misaligned cap âŁor a partially clogged port rather than the â˘cookware itself.
- Nominal heat output: 12000 Btu âfor âŁhigh-heat âsurface cooking tasks
- Key âinterfaces: burner âhead, caporifice, cooktop valve, igniter/ignition⢠module
- Common service â¤actions: cap reseating, âport cleaningorifice⣠verification,â pressure/regulator check

How the â¤WB16T10046 GE Oven Gas Cooktop Large Burner 12000 Btus operates:⢠internal components, gas flowand âŁignition â˘sequence
The â˘WB16T10046 GE Oven Gas Cooktop Large âBurner 12000 btus âis a self-contained⢠burner assembly whose internal parts determine both heat⢠outputâ and safe operation. Gas is supplied âfrom the cooktop manifold through a precisely sized orifice⢠that limits volumetric flow to the â12,000â BTU â˘rating; downstream the gas mixes with⤠primary air and âexits through the burner â¤ports⤠beneathâ the burner cap, where âthe âport geometry and cap profileâ shape the flame âfor even heat. The assembly also includes an⤠ignition âelectrode â(spark), a gas⤠valve⢠or valve mounting bossand a flame-sensing path; these âelements must match the appliance’s inlet pressure andâ mounting interfaces for proper compatibility.In⤠practical terms, replacing a worn WB16T10046 with â¤anâ identical unit⤠preserves factory flow characteristics and â˘avoids issues âsuch as low output, yellow/sooty flames, âor unsafeâ mixture that arise when orifice size or gas pressure⢠are incorrect.
- Burner⤠head and capâ – shapes flame andâ protects ports
- Orifice – meters gas to⣠achieve 12,000 BTU atâ specified pressure
- Ignition⤠electrode/spark⠖ initiates combustion at the⢠ports
- Gas valve interface – controls supply in response âto knob/module
- Flame sensor/rectification path – confirms flame and maintains safety
| Item | Description |
|---|---|
| Orifice | Calibrated â˘opening sized for 12,000 BTU flow at nominal inlet pressure |
| Electrode | High-voltage spark point positioned near ports to ignite air/gas â˘mixture |
| Flame sensor | Uses flame rectification or thermocouple signal to verify ignition and keep valve energized |
The ignition sequence âbegins when âthe control knobâ or electronic controller calls â˘for heat: â¤the spark module beginsâ energizing the electrode while the valveâ is actuated to allow gas to the orifice. As gas issues from the ports, âintermittent sparks ignite the mixture; once⢠aâ continuous flame âŁis detected âby the sensor (typically via flameâ rectification),⢠theâ module⤠stops continuous sparking and the valve remains open for normal⤠operation. If ignition does not âŁoccur withinâ the module’s safetyâ timeout, the valve is closedâ and further attempts⢠may be required. âTechnicians should check electrode gap,port cleanliness,and orifice⣠seating⢠when diagnosing misfires or weak flames,and confirm the part’s BTU/orifice rating and⤠mounting geometry to ensure correct replacement âbehavior. â˘
Common failure symptoms andâ measurable diagnostics for 12,000 btu âlarge burners (ignition, flame qualityand heatâ output)
The WB16T10046 GE Oven Gas Cooktop⢠Large Burner 12000 Btus is a âservice replacement component that provides the primary âhigh-output flame on compatible GE cooktops; its correct operation depends on proper orifice sizing, clean burnerâ ports, a âfunctioning electrode and ignition moduleand correct manifold pressure. Failures typically present as â˘ignition âfailure â¤(no spark âor intermittent sparking), poor flame qualityâ (yellow tipping, liftingor irregular flame pattern)or⣠reduced heat output (low maximum flame or long warm-up times). Technicians should consider compatibility with the cooktop valve and burner head when diagnosing as swapping a 12,000 Btu burner into⣠an âappliance with a different regulator/orifice combination can produce âŁsymptoms similar to component failure rather than a bad burner⤠alone.
Measurable diagnostics focus on electrical continuity and visual/pressure measurements: â¤verify âa visible, consistent spark at âŁthe electrode during ignition cycles, check electrode-to-ground continuity and âinspect the electrode gapâ for carbon buildup or misalignmentand measure valve coil continuity if ignitionâ pulses reach the module â¤but â˘the gas does not flow. For flame-quality and âŁheat-output issues, â¤measureâ static manifold pressure with a manometer during âŁa full-power⣠call to confirm theâ supply matches the appliance design range, inspect âŁand clean âŁports or replace the orifice toâ restore proper âŁflowand compare delivered flame pattern and height against a known-good burner on the same appliance. Practical checks âinclude using a multimeter âŁto confirm open/short conditions, aâ manometer âŁfor inches water column (in. â˘WC) at⤠theâ regulator or pressureâ tapand⣠swapping the suspect WB16T10046 with a confirmed serviceable same-spec burner to isolate valve/regulator⢠faults.
- Ignition: no spark or intermittent spark – âcheck electrode âalignment,gap,ignition module output,and continuity with a multimeter.
- flame quality: â˘yellow, lifting, âŁor uneven â- inspect/clean ports, â˘verify air â¤shutter âand orifice size,â and observe flame under full-power load.
- heat output:⤠low âor inconsistent – âmeasure â¤manifold⢠pressure with a âŁmanometer,⣠checkâ orifice conditionand compare against expected performance for a 12,000 Btu burner.
| Item | Description |
|---|---|
| Electrode âŁgap | Inspect âfor â2-3 â˘mmâ effective gap and clean⤠carbon; misalignment prevents consistent sparking. |
| Manifold pressure | Measure with a manometer at full call; typical cooktop ranges are within a few inches WC â˘of the applianceâ spec. |
| Orifice/ports | Verify⣠correct orifice size for â¤12,000 Btu⤠and clear obstructed ports to restore âŁflame patternâ and output. |

Q&A
What is â˘WB16T10046 and what does⤠“Large⤠Burner 12000 Btus” mean?
WB16T10046 is GE’s replacement âpart number âfor a large gas burner â¤assembly âŁused on â¤certain GE cooktops/ovens. “Large Burner 12000 Btus” indicates the burner⤠isâ rated to deliver up to 12,000 â˘BTU/hour (British Thermal⤠Units),⣠which is its maximum heat output under â˘proper â¤gas pressure and correct orifice sizing.
How do Iâ know if WB16T10046 âŁis compatible with my GE cooktop model?
Check yourâ appliance âmodel⣠number (usually on â˘a tag â˘behind theâ oven door, underâ the cooktopor â¤inside the storage â˘drawer) â˘and compare it to GE’s parts⤠list or an authorized parts⣠dealer. you can also confirm compatibility by searching the partâ number (WB16T10046) âagainst your âŁmodel âon GE’s⢠official parts⢠website or by contacting GE service. Do notâ assume fitment based only on physical similarity-mounting, port alignment and âorificeâ sizing must â˘match your â˘cooktop.
Can I⣠install WB16T10046 myself â˘and what safety precautions â˘should I take?
Replacement is absolutely âŁpossible for a competent diyer, but⢠you must shutâ off the â¤gas âŁsupply and âpower to the appliance before starting. remove grates andâ burner caps, unfasten any retaining screwsand replace the burner âŁbody and âcap âŁensuring proper alignment over the orifice and electrode. After installation, restore gas âand check for leaks at âconnectionsâ with a soapy-water solution (bubbles indicateâ aâ leak).If you are not comfortableâ working with gas lines or cannot confirm proper âŁsealing and ignition, hire a qualified technician.
My new WB16T10046 burner lights but âŁflame is yellow or âsootyâ – what’s wrong?
A healthy gas flame should be mostly blueâ with minimal yellow â¤at the tips.A persistent yellow, sooty flame indicatesâ incomplete combustion due to blocked burner ports, incorrect air shutter adjustment, wrong gasâ type/orificeor low gas pressure.First, clean the burner ports and cap to remove debris. If that doesn’t â˘help, verify the cooktop is set up for the âŁcorrect gas typeâ (natural gas⣠vs. LP);â conversion requires the correct orifice and a conversion⢠kit. â¤If problems persist, have a technician check âŁgas pressureâ and air/gas âmixing.
The burner clicks but does not light – is the problem the â˘WB16T10046 part?
Clicking indicates theâ spark igniter is trying to⣠light the gas. If you get clicking but no ignition, first â¤ensure the burner âports and orifice are clear and â¤that the electrode (igniter) is clean and â˘properly positioned (tip near the ports). If you see a visible spark at the⤠electrode and gas is present,the orifice may be clogged or the gas valveâ not opening fully. if there isâ noâ visible spark, the igniter or wiring may âbe faulty. Troubleshoot by inspecting/cleaning connections; test ignition wiring for continuity and the spark⣠visually. If uncertain, â˘call a⤠service technician.
How should I clean and maintain the WB16T10046â burner?
Allow the cooktop to â˘cool. Remove grates and burnerâ caps,then âŁlift off the burner âhead.⢠Clean burner caps and heads⢠with⤠warm âsoapy water and a âsoft brush; avoid abrasive tools that â˘can âdamage port holes. âUse âa⢠soft brush or compressedâ air to clear clogged ports-do not use metal pins to poke out ports as that can enlarge or deform them. Wipe the electrode âgently to remove food orâ grease. Reassemble ensuring the burner head and cap âseat correctly before testing.
Is WB16T10046 supplied for natural gas or⢠propaneâ (LP)and can it be converted?
The part itself (burner head and cap) is typically the same physical component, but⤠correct operation for LP versus natural gas requires the appropriate orificeâ and sometimes a conversion kit. âMany GE cooktops areâ shipped set forâ natural gas and require a⤠kit and orifice change to operate safely on LP.â Always follow âŁthe âappliance manual âand install the manufacturer-specified conversion kit or have a qualified technician perform â˘the conversion.
How âcan â˘I test âthat the⤠WB16T10046 burner is delivering approximately 12,000 âBTU?
There is no simple home test to measure âBTU output precisely. BTU âdepends on gas pressure and orifice size; you can verify the burner is performing reasonably by observing aâ full, steady blue flame acrossâ theâ ports and comparing heat-up times to the other burners of similar size. â˘for an accurate BTU measurement, a service technician uses a gas flow meter and manometer to measure gas âŁflow and pressure and then calculates the BTU output. If you suspect underperformance,haveâ a professional check gas â˘pressure,orifice â¤sizing,and âregulator operation.
