WB13K10043 GE Oven Ignitor Glowbar is âa hot-surface (glowbar) ignitor assembly used in GE gas ovens and ranges;â it is a⢠resistive heating element designed â¤to reach ignition temperatures quickly and âprovide the thermal⣠energy âneeded⣠to âignite âthe oven burner.â The component is a compact ceramic-based âresistive elementâ enclosed in âa protectiveâ sheath⢠and mounted adjacent to the burner; it is⤠commonly âŁsupplied as a replaceable⢠service part for the bake and â¤broil assemblies on â˘compatibleâ GE appliances.
Inside the appliance, the ignitor’s primary role is to⢠convert electrical energy âinto âheat soâ that released⤠gas â˘will ignite reliably whenâ the gas valve opens. When the oven control calls for heat, mains voltage isâ applied âto the â¤ignitor,⣠the â¤elementâ heats and glowsand the control/gas valve timing⢠isâ coordinated so that gasâ is admitted only after the ignitor reaches the⣠required temperature⣠or âcurrent draw. The glowbar therefore interacts directly with the oven control⤠board, theâ gas safetyâ valve, the burner assembly and the âwiring harness,⣠and â˘its electrical behavior is used by safety circuits to allow âor block⣠gas flow; mechanical mounting and positioning relative⢠to the burner alsoâ affect performance and flame stability.
In this article readers will find a âtechnical overview of âŁthe WB13K10043 part including its function and typical electrical⢠behavior, guidance on model compatibility and â¤part identification, common failure symptoms âandâ causes, stepâbyâstep diagnostic checks (visual inspection, continuity/resistance testing and live-voltage observations) and practical replacementâ considerations such as correct orientation, harness â¤connections and safety⣠precautions.The content âis aimed atâ technicians, engineers and⤠informed appliance ownersâ who need clear, â˘practicalâ information for troubleshooting and⣠replacing a malfunctioning oven ignitor without marketing claims or oversimplification.

Function and Role of the Oven Ignitor in Gas Oven Ignition and Safety Systems
The WB13K10043 GE Oven ignitor Glowbar is âa resistive hot-surface ignitor that provides âthe thermal energy required to ignite âŁthe oven’s main gas burner and to complete the safety circuit enabling the⣠gasâ valve. âAs⤠itâ heats, âŁthe glowbar’s electrical resistance and current âdraw change; the oven control or âgas valve relies â˘on that current draw reaching a specified âŁthreshold before the valve will open. As âthe ignitor⤠both produces theâ ignitionâ source and participates in the⣠valve enable circuit, itsâ warm-up âŁtime, resistance, âand mounting/connector⤠compatibility directly âaffect prosperous ignition âŁand safe operation.
Technicians assess ignitor performance by observing⣠warm-up time, measuring cold resistance andâ operating current, âand inspectingâ for visible damage;â weak âŁor high-resistance units fail to draw⢠sufficient âcurrent, causing long ignition delays⢠or failure to light. âŁWhen replacing theâ glowbar,â match electricalâ ratings, terminal type (typically a two-wire connector)and physical fit to the appliance⢠model to âensure proper âŁfunction. Typical practical⤠indicatorsâ of â˘a failing ignitor âinclude extended preheat time, âfailure of the gas valve â˘to open despite power⤠being present,⤠or âvisibleâ cracking; if there is any âgas âŁodor⣠or persistent⢠ignition âfailure, isolate the âgas⢠supply and have a qualified technicianâ service the range.
- common âsymptomsâ ofâ a failing ignitor: extended âŁignition time,no flame,visible cracks,and reduced â˘measured current draw.
- Key⤠compatibility considerations: â¤electrical ârating,terminal⣠type,and mounting⣠orientation.
- Diagnostic checks:⢠cold resistance measurement,current draw during warm-up,and visual inspection.

How the WB13K10043 GE Oven â˘Ignitor Glowbar âWorksâ Inside the Appliance: electrical Characteristics, Heat-Up Profileand interaction with the Gas Valve
WB13K10043 GE Oven Ignitor Glowbar âis a resistive ceramic glowbar that provides the radiant heat necessary â¤to ignite the oven’sâ gas burner.â When theâ oven controller applies lineâ voltage,⢠the â¤element conducts⣠current â˘and heats until âit emits a visible orange glow; as â˘the element warms its⤠resistance increases, producing a characteristic heat-up profile. Theâ control circuit monitors the ignitor’s electrical behavior (voltage and current signature and/or time-to-glow) and only permits the gas valve to open once⢠the ignitor has reached the required operating temperature. Replacements must match the original part’s electrical characteristics â˘and mounting/connector geometry to âŁensure reliable timingâ and safe valve operation rather than relying on mechanical fit alone.
The⣠ignitor interacts with⢠the gas valve and control logic by presenting a predictable current âŁdraw as it heats: a healthy element reaches operating temperature within tens of seconds⣠and shows the expected change â¤in resistance under load,while a degradedâ or⢠open â˘element fails to glow or âtakesâ much longerâ to heat. Technicians diagnose âŁfaults by visually confirming glow,measuring cold resistanceâ out of circuit,and measuring steady-state current âŁunder line⣠voltage; typical practical checks â˘include confirming â¤theâ element glows within the expected â¤interval andâ verifying âŁconnector type and bracketâ alignmentâ beforeâ installation. For field replacement, âselect âŁaâ unit⤠with â˘matching voltage/current ranges and physical form so the⢠controller’s safety sequence and âvalve timing âŁremain within designedâ limits.
- visual: orange glow within ~8-30â s underâ normal line voltage
- Electrical checks: continuity/cold resistance âŁandâ in-service âcurrent âŁmeasurement
- Compatibility:â matching â˘connector, mounting bracketand⢠electrical ratings
- Failure modes: âopen circuit, high heat-up timeor altered current signature

Common Failure Symptoms of Oven Glowbar Ignitors: Noâ Ignition,Long Preheat,and Intermittent⣠Heating Patterns
The WB13K10043 GE Oven âŁIgnitor âGlowbar âis â˘a resistive ceramic âŁheating element that must reach a specific temperature andâ current draw âŁto allow the oven’s gas valve to open. When the âignitor is healthy it⤠produces a bright, steady glow âŁand drawsâ sufficient â˘current so the safety valve senses⤠the presence of a hot ignitor and âpermits gas flow;⢠a weak or open glowbar will either failâ to âglow â¤at all or glow âonly dimly, preventingâ ignition. Technicians should⣠recognize thatâ a ânon-glowingâ or âvisibly cracked WB13K10043 indicates an openâ circuit or degraded⤠filament; continuity checks âand a bench glow test â(using the correct⤠voltage and safety precautions) are practical first steps beforeâ replacing the⤠part or âŁdiagnosing downstream controls.
Long preheat times and intermittent heating patterns typically occur when the ignitor can âstill heat but draws â¤reduced currentâ or⣠takes much longer to reach operating temperature. This behavior can cause delayed valve opening, short heatingâ cycles â˘that never â˘reach âsetpointor repeated attempts by the âcontrol board to⣠light âthe burner. Practicalâ diagnostics include visually inspecting⢠mounting and electrical connections, measuring continuity and relative resistance against the⢠OEM specificationandâ observing the ignitor under load⣠for steady,⤠full-brightness glow; if bake⢠versus âŁbroilâ performance differs (for example, broil heatsâ normally but bake is slow), the symptom often implicates the ignitor rather than the thermostat or gas valve alone.
- No ignition:â ignitor does not glow or is visibly âbroken.
- Long â˘preheat: âignitor glows weakly âand requires extra time before âvalveâ opens.
- Intermittentâ heating:â oven⣠cycles unpredictably âŁor fails â¤to reach temperature consistently.
| Item | Description |
|---|---|
| No ignition | Open â˘or failed glowbar; no current drawâ so⤠gas valve remains closed. |
| Long⤠preheat / intermittent âheating | partial failure or high resistanceâ in the ignitorâ causing reduced current draw and delayed valve actuation. |
Compatibility and Appliance Models: OEM cross-References,⤠Fitmentand Model-Specific Installation Notes
The WB13K10043 GEâ oven⤠Ignitor Glowbar is a resistive glowbar-type igniterâ used toâ heat the⤠oven burner manifold until it reaches⢠incandescence and the gas safety⣠circuit opens the âŁvalve. It operates âas a high-temperature resistive element on standard 120 V AC residential supplies; the igniter’s âŁelectrical and thermal behavior⤠– â¤warm-up â¤time, steady-state current â˘drawand mechanical âŁgeometryâ – determine whether the oven’s gas valve receives the required âsignal⢠to release gas. Typical failureâ modes are increased warm-up time, reduced⢠current draw (preventing valve actuation), cracks in theâ ceramic/glass âenvelopeor open-circuit conditions that stop âŁignition entirely.
Compatibility is governed by âŁphysical fitment and âelectrical âmatchâ rather than by brand name alone. âŁTechnicians⢠mustâ matchâ mounting flange⢠dimensions, terminal style â(spade terminals vs. pigtail harness),⣠lead lengthand the â¤element’s orientation to the burner port; mismatches can prevent proper alignment with â˘the gas valve or âcause âwiring âstress.⢠Before⢠replacement, confirm the oven âŁmodelâ number against the manufacturer â¤cross-referenceâ and inspect the⣠original igniter forâ bracket type and connector. practical installation notes: disconnect⤠power and gas,â verify continuity of the old element âwith a meter, âavoid touching â¤theâ glass surface of the⤠new igniter with bare âhands, âsecure⢠theâ mounting to maintain properâ gap to the burner,⣠andâ test the oven through a full ignition cycle toâ confirm correct warm-up time and valveâ operation.
- Connector type and âpolarity: ensure the replacement uses theâ same terminals orâ an approved adapter.
- Mounting âgeometry: flange position and screw âhole spacing determine physical compatibility.
- Lead length and insulation: prevents chafing âand maintains clearance â¤from hot components.
- Pre-install tests: continuity check and visual âinspection for cracks or carbon⣠tracking.

Replacementâ Considerations and âInstallation Best Practices: Mounting, Wiring, âGaskets, â¤and Safety Precautions
The⣠WB13K10043 âGE Oven Ignitor Glowbar must â˘be mounted and sealed so that its ceramic body and electricalâ leads âremain clear of sharp edges, insulation fibersand the âŁburner flame â¤path while still âtransferring heat efficiently âto the gas valve sensing/ignition zone. Verify the ignitor’s flange⤠orientation â˘and hole pattern against âŁthe oven’s mounting bracket before âfastening; âŁan incorrect offset â˘or twisted bracket can place the glowbar too close to aluminized âsteel or insulation, âcausing premature cracking âŁor shorting. âŁWhen a gasket or âceramic seal is used at the penetration âpoint, replace it with an⤠equivalent high-temperature material-avoid general-purpose silicone or low-temperature adhesives-so⣠the cavity retains thermal isolation and the lead wires are protected from chafing⤠during service. âConfirmâ part compatibility with the oven harness and mounting geometry rather than relying⤠solely on visual similarity: matching electrical connector type,lead length,and mounting hole⣠spacing prevents field modifications that can create mechanical stress on the glowbar.
Always removeâ AC power at⣠the breaker â˘and shut the gas supply before âdisconnecting the old ignitor; follow with a continuity check andâ a visual inspection of the harness insulation⤠and connectors. Use high-temperature-rated crimp or ceramic âinsulated terminals and secure leads with strain reliefs routed away from hot components; avoid solder joints where heat-cycling canâ soften the âjoint. After installation, restore power and âŁgas and perform functional checks: the glowbar shouldâ reach aâ bright âorange within a few seconds and the gas âvalve should open; perform â¤a gas-leak test at the service âfittings and observe the⢠flame behavior for severalâ ignition cycles. practical âpre-install checks include confirming connector polarity (if â¤applicable), verifying the â¤replacement part number â˘against the âmodel plateand⤠replacing any burned âŁorâ brittle gaskets to maintain⣠correct thermal â˘and mechanical âbehavior.
- Power⣠and gas off, verify part number and harness fit before removal.
- Inspect and replace highâtemperature gaskets/insulation as needed.
- Use high-temp crimp/ceramic connectors; secure â¤leads âwith strain relief.
- Perform continuityâ and operational glow/valve tests; leak-test gas connections.

Troubleshooting âandâ Diagnostics: âMultimeter Tests,Current Draw Measurements,and Step-by-Step âfaultâ Isolation
The WB13K10043 GE Oven Ignitor Glowbar ⣠is âa hot-surface âignitor âthat must reach⣠a specific temperature and resistance profile to reliably light the gas burner. For bench âŁdiagnostics use âa digital multimeter set to the ohms rangeâ with the ignitor disconnected from the oven harness; a healthy glowbarâ will âshow a low but finite cold resistance (commonly in the low tensâ of ohms) âand âdefinite continuity. Anâ open circuit or extremely high âresistance indicates an internal break, while visible cracking or âdiscoloration also correlates withâ imminent failure. Confirm connector pins, harness integrityand the⣠control module output before condemning the ignitor toâ avoid⤠misattributing wiring or control faultsâ to the element itself.
Current draw⤠measurements distinguish a weak or partially failedâ element from wiring or control faults: measure live current during an ignition⤠cycle either with a clamp⣠meter clamped around a single⢠conductor to the ignitor⣠or by â˘placing a true RMS ammeter â¤in series with the circuit. Expect severalâ amps â˘during the warm-up period; significantly lower than expected âcurrent suggests âhigh internal resistance â¤in the glowbar,and significantly higher current suggests a shorted element⤠or incorrect supply voltage. For systematic âfault âŁisolation, follow these âsteps and consult the reference âvalues â˘below to interpret results safely and reproducibly.
- Power off⤠and disconnectâ the ignitor before resistance/continuity checks.
- Measureâ cold resistance across theâ ignitor âleads with the harness unplugged.
- Inspect theâ element âŁvisually for cracks, blisters, â˘or breaksâ in the ceramic coating.
- Measure operating current with a clamp⤠meter on one âconductor⢠or an ammeter in⤠series while the oven attempts to ignite.
- If resistance/⢠current âŁare out of range, â¤verify harness, relaysand control board outputs before âreplacing the ignitor.

Q&A
What is the WB13K10043⣠ignitor glowbar and what does it do in my GE oven?
The âWB13K10043 is âa hot-surface (glowbar)â ignitor usedâ on many GE/Hotpoint/Jenn-Air gas ovens⤠and ranges. When the oven calls for heat the control sends⣠line voltage to theâ ignitor, the glowbar âheats to a bright redand once it reaches â¤sufficient temperature it allows the gas safety valve to open so the burner can light. It is â˘not⤠a spark ignitor – it lights the gas by heating rather⣠than producing a spark.
What â˘are the common symptoms â˘of aâ failing WB13K10043?
Common signs include: the oven takes a long â˘time âto light or â˘never âŁlights,⢠the ignitor glows but burnerâ doesn’t ignite, intermittentâ ignition, the broil/bake burners fail while surface burners workor the oven cycles and will not âreach set temperature. Physicalâ cracks or broken ceramic â˘on the ignitor are alsoâ a clear failure indication.
How can I test the ignitor to â¤see⣠if⣠it’s bad?
Two reliable tests: 1) Current draw â¤test â- using a clampâ ammeter measure current on the ignitor feed while it’sâ trying to light. Aâ healthy glowbar âtypically⢠pulls roughly âin âŁthe 2.5-3.5⣠A⤠range when hot (specs vary by model); if⤠it draws significantly less thanâ the manufacturer’s spec it mayâ not open the gas valve. 2) Visual/continuity check -⢠with power⢠off you can inspect for cracks âand check for âcontinuity âwithâ an ohmmeterâ (cold âresistance varies between designs, so continuity only shows it’s not an open⤠circuit).â As â¤cold resistance varies, the amp draw test is the definitive functionalâ test. Always â¤consult the oven’s service manual for the exact⣠current/resistance spec.
Can I replace the WB13K10043 myself âŁand âŁwhat are the basic steps?
Technically yes if âyou have basic electrical skills, the right tools and followâ safety precautions. Basic steps: 1) Disconnect electrical powerâ to the appliance at the breaker box and shut off âthe gasâ supply. 2) Access the ignitor (usually by removing the⤠oven bottom, burner access panel orâ broiler drawer and aâ mounting âŁbracket). â3) Disconnect the two electrical terminals âand remove mounting screws, â˘being careful-the ceramicâ element is fragile. 4) Install the new⤠ignitor making â˘sure terminals andâ mountingâ position âmatch theâ original, reassemble â˘panels,â restore⤠gas and⣠powerand test. If you are uncomfortable with electrical or gas work, hire a qualified technician.
my ignitor glows âbut the â¤burner still won’t light – isâ the ignitor âstill âbad?
Not⤠always. If the ignitor glows but current draw is too low it may⤠failâ to open the gas safety valve âeven â˘though âit appears hot. Other possible causes include a failing gas⢠safety valve, blockedâ gas orifice,⢠faulty âŁcontrol âŁboard or safety â˘interlocks.â Use a clamp⣠ammeter to confirm the ignitor is pullingâ sufficient current;â if it is and gas valve doesn’t open,the valve or control should beâ tested next by a trained technician.
How⢠long do these glowbar ignitors usually last?
Typical life is several years – often 5-10 years – but it varies with usage, power surges, switching cyclesand â˘environmental factors (moisture, grease). Frequent on-off⣠cycles and high humidity/steam canâ shorten life. If an âignitor has been in service many⣠years and showsâ degradation,⣠replacement is usually appropriate.
Is the WB13K10043⣠compatible â˘with my oven model? Howâ do I make sure Iâ buy the right part?
The WB13K10043 is a commonâ OEM part used across many GE-family models, but compatibility depends on model/year⢠and burner style. theâ safest method: â¤check âyour oven’s model number (usually onâ a tag on theâ oven⣠door frame or behind the cooktop) âand confirm the part number in âtheâ manufacturer’s parts list or at â¤an authorized parts supplier. Aftermarket equivalents âexist, âbut matching terminal â¤style, mounting holes and electricalâ ratings is essential.
If I replace the ignitor and the âoven âstill won’t light, what should I check next?
If a âŁnew â¤ignitor still âwon’t light the burner, ânext steps â¤include:â verify the ignitor’s current draw matches spec, â¤inspect/clean the âŁburner and orifice for âblockages, check âthe âŁgas supply⣠and shutoff â¤valveand test the gas safety valve and control board. Becauseâ gas valve testing and replacement involve gas safety and⢠specific â˘electrical tests, contact a qualified appliance âtechnician âif the problemâ persists after replacingâ the â˘ignitor.
Key Takeaways
the WB13K10043 GE Oven Ignitor glowbar is a⢠critical component in gas oven operation, providing the heat⤠necessaryâ to initiate combustion and⢠maintain reliableâ ignition. Its consistent performance affects oven preheat times,⢠cooking accuracy âand overall appliance efficiency, â˘andâ a properly functioning glowbar contributes to safe and predictable operationâ of the range.
Because ignition problems canâ stem from a range of causes, âaccurateâ diagnosis is meaningful before replacement. âŁVisual inspection and objective testing help distinguish a âfailing â˘ignitor from issues such as gasâ supply, safetyâ valvesor control circuitry, enabling a targetedâ repair.
