WB13T10045 GE Oven Ignitor Assembly⣠isâ a hot-surface ignitor (glow-bar) assembly⣠used inâ gas ovens and ranges; it âconsistsâ ofâ a⢠resistive⢠heatingâ element, âmounting⤠bracketand two-wire â¤connector âŁdesigned to reachâ ignition â¤temperature and provide the âŁelectrical load required by â˘the appliance’s gasâ valve/proving circuit. As a replaceable component it âisâ typically⢠soldâ and installed⤠as âa⣠single assembly to ârestore⤠the ignition function on compatible⢠GE gas âovens and similar appliance designs.
Inside the appliance,the ignitor is âŁpart âof the gas ignition system and âthe oven’s âsafety interlock chain. When the â˘control board calls for heat, âit supplies line voltage to the â¤ignitor so the element heats toâ a high temperature and⢠togetherâ draws the currentâ necessaryâ to actuate the gas⢠safety âŁvalve; once the valve opens â˘and gas flows,â the âhotâ surface⣠ignites the burner.The ignitor therefore interacts directly with the ovenâ control module, âŁthe gas safety valve, associated wiring and âconnectorsand âŁwith temperature âŁcontrol/feedback âŁelements âthat â¤govern bake â¤and broil cycles. Its proper electrical resistance, â¤mounting âposition â¤and thermal âisolation are important to ensure consistent âignitionâ timing and to avoid nuisance lockouts or⣠delayed ignitionâ events that⤠can âŁaffect safety and performance.
Thisâ article will âŁdescribe the âŁWB13T10045’s operating principle and typical physical andâ electrical⣠characteristics,⤠outline âmodelâ and compatibility considerations, identify commonâ failure symptoms and âinspection pointsand provide âŁa⣠structured⣠approach to diagnosticâ checks and â˘replacement considerations for â˘technicians andâ experienced âŁappliance⢠owners. Practical topics will â¤include how the ignitor âfits into the ignition sequence, â˘what measurements and⢠visual checks are â¤useful during âtroubleshooting, âand factors toâ observe⤠when selecting and installing a âreplacement⣠assembly to ensure safe, correct operation.

Function âŁand Role⢠of the Oven ignitor:⤠ignition heating,â gas-valve controland safety interfaces
The WB13T10045 GE oven Ignitorâ Assembly âis a hot-surface igniter that provides⣠theâ thermal and electrical âŁbehavior ârequiredâ to âinitiate combustion in gasâ ovens. âWhen the control calls âfor⢠heat, the ignitor element heatsâ until⤠it glows; its hot resistance andâ resulting current draw are what allow the oven’s gas valve coils to energize and open. A properly functioning ignitor must reach a⢠low enough operating⣠resistance to pass the rated coil current-anâ ignitor âthat glows but âŁhas increased âresistance can âŁprevent the valve from opening even though it âappears⢠to be working. Compatibility â¤with the oven’s connector, mounting bracketand heat shield is essential when replacing the âassembly to ensure correctâ mechanical fit and reliable electrical contact.
Oven control and safety circuits monitor ignitor performance âand interlock gas flow until safe ignition is verified. If the ignitor âdoes not reach âthe required current withinâ the controller’s timeout⢠period, the control âwill lock⢠out âgas to âŁprevent accumulation.Flame-proving devices âor âtemperature sensors âthen confirm combustion; if â˘flame is not â¤detected the control de-energizes the â˘valve. Practical âdiagnostics includeâ measuring cold continuity and resistance, observing warm current âŁwith aâ clamp ammeterandâ checking for long⣠glow times or delayed⣠ignition as â˘indicators of weak⣠output. When replacing the assembly, match the part to the appliance model âand check for secure electricalâ splices and âintact insulation to avoid nuisance lockouts âor unsafe operation.
- Common symptoms: prolonged glow time, oven fails âto ignite,â or intermittent ignitionâ cycles.
- Typical checks: âcold resistance continuity, warm current measurementand connector/mounting verification.
- Safety behavior: control timeout prevents valve energization⤠until adequate ignitor âcurrent is detected.

How the WB13T10045 GE Oven Ignitor âAssembly Worksâ Inside the Appliance
The WB13T10045 GE âOven Ignitor Assembly is a â¤hot-surface ignition device that transforms âelectricalâ energy into thermal energy to initiate gas â˘flow⣠in the⢠oven⣠burner circuit.The assembly contains a âŁceramic-encased resistive element that, when supplied with mains voltage, heats ârapidly untilâ it âemits a visible orange glow; this thermal output is detected by the oven control or allowsâ sufficient current âto flow to â¤actuate⢠the gas safety valve. In typical household â¤installations the ignitorâ is connected to the appliance’s 120 V supply and isâ positioned⤠toâ heat a pilotâ or main âŁburner port directly,so correct â˘orientationâ and secure electrical connections are necessary for âŁreliableâ ignition.
Functionally, the ignitor actsâ as both â¤a âŁheater and a current-limited switch: its resistanceâ drops asâ temperature risesand the⤠resulting current draw signals âthe controlâ or energizesâ theâ gas valve. Techniciansâ commonly diagnose a weak ignitor by measuring its coldâ resistance, observing a delayed orâ dim glow,⤠or measuring the amp draw⢠during â¤warm-up; a part that â¤glows butâ never reaches fullâ intensity usually cannot open the valve even though it⣠appears to â¤operate. âWhen replacing the component, match the â˘WB13T10045 GE Oven Ignitor assembly toâ the oven’s âmounting, connector typeand specified electrical â¤characteristics⢠to ensure compatibility and maintain burner sequencingâ and safetyâ interlocks.
- slow or dim glow with long ignition delay⤠– âusuallyâ indicates reduced element output or end-of-life.
- No glow â˘or open circuit – âŁelectrical fault or failed ignitor; verify power âŁand continuity⣠first.
- Glows⣠butâ burners⤠do not light – likely insufficientâ current â¤to⢠operateâ the gas valve despiteâ visible heating.
- Sparkingâ or unusual behavior âat connectors – inspect wiring â˘and terminals âŁfor corrosion or loose fit.

Common Failure Symptoms andâ Diagnostic âIndicators âŁfor âOven⢠Ignitor âFaults
The WB13T10045 GE Oven Ignitor Assembly is a hot-surface âŁignitionâ component that heats âto â˘a visible orange glow to initiate gas flow and combustion in compatible GE range/oven models. âThe âignitor must reach a⣠specified temperature and draw sufficient current to allow the âgas â˘valve to open; âif â¤the âŁelement ages or the assembly is damaged, the glow might potentially be dim, âŁslow⣠to reach temperatureor absent entirely,⢠resulting â¤inâ long preheat âtimes, failure to⤠lightor repeated safety lockouts. The âassembly typically âincludes⢠the ceramic/glass-sealed âfilament and mounting âŁhardware; always verify model compatibility and connector type beforeâ replacing the part to âensure proper fit and electrical match with the oven’s control âand âgas âvalve circuit.
- Oven won’tâ light âŁor⤠requires long preheatâ times
- Ignitor glows âweaklyâ or not at âŁallor âglows but gasâ does not ignite
- Intermittent ignition, frequent⤠clicking fromâ the gasâ valve, â˘or oven cycling⤠without â¤sustained flame
- Visible âcracking, burn-through, âŁor broken leads at⤠the assembly
- Smell of⢠gas with no ignition⢠(safetyâ hazard-shut off âgas and power before⣠diagnostics)
| item | description |
|---|---|
| Visual glow | Expect âa steady orange/red glow within several seconds;⣠dim or delayed glow indicates reduced âŁemission âand likelyâ replacement. |
| Continuity / Resistance | Use a multimeter: an âopen âcircuit means a âŁfailed filament; unusually⤠high resistance compared⣠with⣠a known-good unit suggests degradation. |
| Current draw | Measure âamp â¤draw under operatingâ voltage and⢠compare to manufacturer⣠or a known-good ignitor; a substantially lower current indicates âŁthe element cannot reach ignition temperature. |
Diagnosing âŁa suspected WB13T10045â failure⣠combines âvisual inspection with electrical⤠measurement: first isolate power and⢠inspect for physical damage or looseâ connectors, âthen measure continuity â˘and, if⢠safe⤠to doâ so, âcurrent under supply voltage whileâ observing glow â˘behavior. Such as, anâ ignitor âŁthatâ glows⢠but â¤fails to open âthe⢠gas valve often exhibits adequate continuity but reduced âcurrent draw;⤠conversely, âan âopen circuit or âŁvisibleâ fracture requires⣠immediate replacement. â¤When readings are borderline, replacing â˘the ignitor âis usually the most practical remedy asâ inconsistent heat output shortens⤠gas valve life and can lead to repeated â¤service calls. Always followâ safety procedures: shut off power and gas âbefore⢠disconnectingâ componentsandâ verify âcompatibility of the replacement part with â˘the oven model and control âelectronics.
Troubleshooting â¤and Diagnostics: measurement procedures, tests, âand repairâ decisionâ criteria
The WB13T10045 GEâ Oven Ignitor Assembly is a hot-surface glow⢠ignitorâ that converts electrical⤠energy into â˘radiant â˘heat to initiate gasâ flow in⢠the oven burner assembly. In⤠normal operation the â¤element reaches âa high surfaceâ temperature and presentsâ a low-resistance path thatâ draws the required⤠currentâ to⤠allow the gas â˘valve to open; if the element cannot reach the⣠required âtemperature or âis âelectrically open, â˘the valve circuit âwill not âenergize and âthe burner will not light.â Confirm â˘physical⢠fit, mounting⤠holes,â and connector type against⤠the oven â¤model numberâ before â˘installation, âŁsince electrical⢠and âmechanical⣠compatibility âdetermine whether a replacement ignitor will perform â¤correctly in a specific GE⤠oven or retrofitted appliance.
Diagnose⣠the ignitor by âsequential checks: â˘a visual inspection for âcracks âor â¤contamination, a âŁcold resistance/continuity check with the⣠assembly isolatedand a live functional test during a â˘controlled bakeâ call while monitoring âvoltage and current. Useâ a digitalâ multimeter to confirm âcontinuity; an open⤠reading indicatesâ element failure. During âŁa powered test, verify the â¤ignitor glows evenly andâ draws the⣠oven’s specifiedâ operating current; âŁan element that glows dimly, takes excessively longâ to âreach â˘operating glow,⢠or draws insufficient currentâ relative to the oven’s valve⤠requirements should be replaced. Typical repair criteria: replace the ignitor ifâ it is electricallyâ open,⤠physically damagedor âfails to âreach⢠the âŁoperational glow/currentâ required to actuate theâ gas âvalve when measured against the appliance’sâ service specifications.
- No glow or⢠open circuit on â˘resistance⤠check – â¤replace ignitor.
- Dim âor slow-to-glow element with low measured current under load – symptomatic of degraded output; replace.
- Intermittent operation or visible âcracking -⤠replace⣠to prevent unpredictable ignition failures.
- Proper glow and expectedâ currentâ draw but⢠no gas flow -⣠inspect valve âand control â¤circuit (ignitor mayâ be functional).
| Item | Description |
|---|---|
| Cold âresistance⣠/ continuity | Measured âwith ignitor isolated; an openâ circuit indicatesâ element âbreak.compare measured âvalue to OEM â˘spec⢠for a â¤definitive pass/fail. |
| Live functional behavior | Ignitor should â¤reachâ bright â˘glow⢠and draw sufficient current to allow the⣠gas valve⣠to energize;⢠slow warm-up or low âcurrent indicates⢠loss of âemissive capability and warrants replacement. |
Q&A
What is⤠the WB13T10045 and what doesâ it âdoâ in my GE oven?
The âWB13T10045 is a hot-surface oven ignitor assembly used on âmanyâ GE/Hotpoint/Kenmore⣠gas â˘ovens. Whenâ the oven calls for âŁheat the ignitor heats until it glows red-hot; the current through the glowing â˘element allows the⢠oven’s â¤gas safety valve to open and gas to flow to theâ burner⣠so the oven can ignite. âIt is⢠indeed not a spark igniter-it⤠lights by providing heat, not a spark.
what â˘are⤠the⤠common symptoms⢠of a âfailing WB13T10045?
Common signs âinclude the ovenâ not lighting (gas valveâ clicks but burner does not ignite),⣠very long ignition delays, oven taking⢠unusually longâ to preheator âtheâ ignitor glowing âdim instead âof bright orange. A wholly failed ignitor will show as an open⣠circuit⢠(no â¤continuity) or⣠will not draw sufficient current to open the gasâ valve.
Can I replace theâ WB13T10045 âmyself,andâ what âŁsafety âsteps should I follow?
Yes,a competent DIYer can⢠replace this ignitor,but follow âŁsafety steps: disconnect⣠electrical power â¤toâ the range and turn off the gas supply âbefore â¤starting.â Allow âthe oven â¤to cool,â avoid touching the ignitor element⢠with bare âhands (oilâ shortens element⣠life)and handle the⢠glass/ceramic carefully. If you are uncomfortableâ with gas/electrical â¤work, hire a qualified applianceâ technician.
How do I test⤠the WB13T10045â to know if âit’s âŁbad?
Start with a continuity âŁcheck using a multimeter-an â¤open circuit âindicates a failed ignitor.A more âreliable test is an amp drawâ test (using aâ clamp meter) while the âoven is â¤calling for heat; a â¤weak or low current drawâ compared with the oven’s required spec means the â¤ignitor isâ weak and should be replaced. âexact âresistance or amp specs vary by⢠model-refer â˘to the â˘appliance service manual âor partâ documentation for the correct values before making aâ diagnosis.
Is WB13T10045 an â˘OEM part and will an aftermarket part â¤work?
WB13T10045 is sold â˘as a factory-styleâ replacement for âcertain GE/Hotpoint/Kenmore ovens.Aftermarket equivalents âare âavailable â¤andâ often work fine, but quality varies. For best âŁreliability and fit, use⢠the OEM âpart or a high-quality aftermarket⢠part that⢠is specified as âcompatible with your oven model. Always âŁcross-reference by your applianceâ model number, not just theâ part number, to⣠ensure compatibility.
How long does theâ WB13T10045 typically last?
Lifespan varies withâ use and conditions but a properly installed ignitor typically lasts several⢠years (frequently enough 3-10 years).â Factorsâ that shorten⣠life⤠include frequent cycling,rough handling,or âcontamination â(oils/grease on the element). If the ignitor becomes⢠cracked or theâ glass envelope âŁis âdamaged, replace it promptly.
Do I need to adjust anything⣠after installing the ânew âWB13T10045?
Generally⣠no special adjustments are needed-install the⣠new assembly, secure the mounting⢠screws,â reconnect the âŁwiring (observe any âŁrouting âclips), restore â˘power andâ gasand test operation. If ignition⤠delay or flame âŁissues persist after installing a known-good ignitor, further diagnosis of the gas valve, safety thermostatorâ control board is âŁwarranted.
How canâ I find the correct replacement⣠WB13T10045 for my oven model?
Locate your oven’s model number (usually âon the frame behind the oven door or on the oven âdoorâ trim) âŁand check⤠the GEâ parts lookup,appliance â˘retailer,or authorized⢠parts distributor. Enter the model number to verify parts compatibility orâ use the OEM part number WB13T10045 as a reference. If in doubt, contact the manufacturer orâ a qualified parts⣠dealer withâ your model number for⢠confirmation.
