WB13T10045â GE oven Ignitor Assembly is a hot-surface ignitorâ (commonly called⤠a glow-bar ignitor) designed for use in âgas ovens âand ranges. The assembly typically âconsists of a ceramic-encased resistive elementâ mountedâ in a bracket with a wiring â˘harness âŁor connector;â its construction is intended to produce a⢠controlled â˘incandescent surface that provides⣠the thermal energy required to ignite incoming âgas.⢠As a discrete replaceable âcomponent,⤠it is identified by the WB13T10045 part â˘number âfor compatibilityâ and service reference.
Within âthe â¤appliance, âŁthe ignitor is aâ key element of the gas â˘ignition system: when the oven control requests â¤heat, the control board applies⣠line voltage to the â¤ignitor so it heats âŁto an incandescent temperature. âŁThe ignitor’sâ electrical and thermal characteristics determine the current draw âŁand the timing used by the control âand gas⢠valve assembly; âonce the element reaches the rated operatingâ condition, the â¤gas âvalve is allowed to open and âthe gas is⢠ignited by the hot surface. The ignitor⣠interacts directly with the oven control âmodule, the gas safety valve, the burner/broiler assembly and the wiring harnessand its âcondition therefore affects ignition reliability, safety interlocks,⣠and the oven’s ability âtoâ reach and maintain set temperatures.
this article will⤠explain the WB13T10045’sâ operating principles, whereâ it is indeed typically installed in âGE gasâ ovensand how to identify⤠compatible models and mounting âvariants. It will⣠outline âcommon â˘failure symptoms and their likely causes, describe diagnostic checksâ a technician can use (visual inspection, âelectrical measurements and performance observations), âand cover practical replacement considerations such as connector types, mounting orientation and safety precautions. The intent is to provide enough technical context for appliance technicians, â˘engineers and âknowledgeable owners to assess functionality, plan safe troubleshootingand select an â˘appropriateâ replacement whenâ required.

Function and âRole of the WB13T10045 GE Oven Ignitor Assembly⢠in Gas Oven Safety and âŁHeat Control
The WB13T10045â GE Oven⣠Ignitor Assembly is â˘a glow-bar ignitorâ used in many GEâ gas ovens to initiate and âverify burner ignition.As âthe ignitor element heats, its electrical⣠characteristics change-its filament warms and allows sufficient current flow through the circuit that â¤opens the gas safety valve. Untilâ the ignitor reaches its operating temperature and draws the required current, the valve remains closed; this behavior provides a built-in safety interlock âthatâ prevents⤠raw gas flow âwhen⢠ignition energy is â˘insufficient. âTechniciansâ commonly⤠verify correct operation by âobserving the visible glow, checking âfor consistent warm-up timeand measuring circuit current or continuity at the harness⤠rather than relying onâ appearance alone.
- Primary function: provide heat to ignite gas andâ allow gas valve âoperation only after safe ignition conditions are met.
- Common â˘failureâ modes: weakened glow, extendedâ ignition delayor open circuit leading to oven not heating.
- Compatibility considerations: âensure⢠matchingâ mounting⣠dimensions, connector typeand electrical ratings for correct fit and reliable operation.
- Diagnostic approach: inspect wiring and⢠mounting, watchâ glow timingand test circuit current to confirm sufficient â˘draw â˘for valve operation.

|---|---|
| component âtype | Glow-bar ignitor assembly used on gas oven burners |
| Operational role | Heat to ignition temperature âand â˘enableâ gasâ valve by drawing rated current |
| Typical â¤symptom of⤠failure | Oven fails â˘to light, long preheat timesor repeated ignitionâ attempts |
| Service note | Replace⤠with a part that matches physical and electrical specifications; verify with multimeter/ammeter |
Beyond initial ignition, theâ ignitor affects temperatureâ controlâ and⣠cycle âŁstability as modern control boards monitor flame establishment and⣠adjust burner runtime accordingly. â¤A marginal ignitorâ can âcauseâ the controller⢠to terminate âattempts prematurely or âŁextend preheat⢠cycles,producing inconsistent â˘oven temperatures or triggering diagnostic fault codes. In practice,replacement decisions should consider âŁconnector compatibility,mounting bracket alignment,and observed⣠electrical⢠behavior under â¤load; replacing the ignitor âwithout correcting⣠wiring or valve problems can leave the underlying⤠issue unresolved. For safety and accuracy, â¤repairs involving âŁgas components âand electrical tests are⢠best⢠performed â¤by qualifiedâ service personnel using appropriate test equipment.
How the WB13T10045â GE Oven Ignitor Assembly âWorks Inside the Appliance:⣠Ignition âŁCircuit, Glow Characteristicsand â˘thermal Response
The WB13T10045 âGE Oven Ignitor Assembly is a⢠resistive, sealed-glass glowâ bar âŁthat â¤functions⢠as the primary heating element within the oven ignition circuit. When the controller⤠sends⤠voltage to the circuit, the ignitor glows incandescent â˘and âŁits electrical resistance âfalls as âŁit reaches operating temperature; that drop â˘in resistance allows sufficient⣠current to flow through the series-connected gas safety valve so the valve⢠can open and gas can be ignited. The visible âglow âis a reliable indicator of element heating – a âradiant, steady âŁorange-white glow indicatesâ the ignitor is reaching⢠its⣠target⣠temperature and âcurrent draw, âwhereas a dim, slow-to-develop glow often⣠correlates with increased⢠coldâ resistance and â¤insufficient current to operateâ the valve.
- Typical failure symptoms: slow preheat, gas valve⣠clicking without ignition, faint or no glow.
- Non-live âchecks technicians use: continuity and cold-resistance âmeasurement with a⢠digital multimeter.
- Operational behavior: steady incandescent glow, resistance decrease as temperature rises,â heat-up time measurable âin⢠seconds.
thermally, the assembly is designed to reach high surface temperaturesâ quickly; a âtypical warm-up to âfull glow takes on the order of 10-30 seconds depending on line â¤voltage and ambient⢠conditionsand aging increases time-to-glow by raising filament⤠resistance. âFor practical troubleshooting, a cold-resistance reading âŁoutside the expected range or anâ unusually long glow-up time points â¤to replacement⤠rather âthan valve â˘or control â¤failure. The WB13T10045 âis âan OEM-style element â¤intended for direct replacement inâ compatible GE⤠ovens; technicians â˘should verify âŁmodel compatibility âand compare measured resistance âand observed glow behavior to manufacturer references âŁbefore concluding⤠the ignitorâ is the root cause.
| Item | Description |
|---|---|
| Operating temperature | Incandescent surface temperature typically in the range⢠of 1000-1400 °F when at âfull glow |
| Typical âwarm-up time | Approximately 10-30 seconds to reach â¤full glow depending on supply voltage and aging |
| Cold resistance (approx.) | Measured with multimeter; commonly on the order of tens to a few hundred ohms â(varies by design) |
Common Failure Symptoms and Measurable Diagnostic âIndicators for the Ignitor Assembly
The âŁWB13T10045 GE Ovenâ Ignitor Assembly is a resistive â¤hot-surface ignition elementâ used to initiate combustion in compatible â¤GE gas⢠ovens. when the oven control calls âfor heat, the ignitor converts line voltage into heat and must reach a specific⤠surface temperature âŁand âglow intensity to allow the gas valveâ to open; if âits electrical âor thermal behavior deviates from expected values the valve will notâ energize. Theâ part behaves⢠like âa low-value⣠resistor when cold and will present continuity on a multimeter if intact. compatibility is limited to⣠ovens designed for a hot-surface⤠ignitor âof this form factor and electrical rating; replacing a different âignitor type or a part with incompatible resistance characteristics can prevent properâ valveâ operation or stress âthe control circuitry.
Technically useful diagnostic indicators include static⢠electrical checks (continuity⢠and âŁcold resistance), âdynamic electrical checks (presence of approximately line voltage at the âignitor⣠harness â¤whileâ the controller calls for heat)andâ timed⤠thermal behavior⣠(time-to-glow and glow intensity). Such as, an ignitor that reads open (infinite resistance)â on a multimeter is failedâ and âmustâ be replaced,⤠while âan ignitor that glows very slowly or not to bright orange within a moderate âinterval is degrading and may draw insufficient current toâ actuate the gas valve. If voltage is presentâ at the connector but the element does not⤠glow, the fault is the ignitor; if the ignitor glows normally yet theâ burner does â˘not âlight, the gas valve or control circuit should beâ tested⢠next.
- Visible/functional symptom: no ignition or âŁlong pre-ignition glow period.
- Resistance check: continuity present; resistance within expected coldâ range for the oven family.
- Voltage check: ~120â VAC present at the harness when calling for heat.
- Thermalâ timing: element reachesâ full â˘orange glow within tens of seconds under normal â¤conditions.
| Item | Description |
|---|---|
| Typical cold â˘resistance | Model-dependent; commonly measured âŁin the low hundreds of ohms.⣠Values well outside theâ expected range (very âhigh or infinite)â indicate failure. |
| visible glow time | Should âŁreach bright⣠orange within a short interval (tens of seconds).⢠Substantially longer times â¤indicate degradation. |
| Voltage at connector | Lineâ voltage âŁ(~120 âVAC) should appear at the ignitor harness when the â¤control calls for heat; voltage with no⣠glow points⢠to a failed ignitor. |
Replacement Considerations and StepâbyâStep Installation for WB13T10045 GE Oven Ignitor assembly, Wiringand âŁSafety Checks
The WB13T10045 GE Oven Ignitor Assemblyâ is a hotâsurface ignitor that creates the necessaryâ heat to⤠open the oven â¤gas safety valve by reaching incandescent temperatures and conducting the initial current for âvalveâ actuation. Inâ normal operation the element must glow⤠visibly within a âŁfewâ seconds of a bake or broil call and sustain that glow until the gas valve opens; symptoms such as a slow â˘glow, intermittent lighting,⣠long ignition delays, â¤or complete⢠failure to glowâ indicate reduced emission from the⤠element or anâ open filament. Technically, a failing â˘ignitor alters the current draw â¤and voltage profile of the â¤burner circuit, so â¤troubleshooting should â˘include both visual inspectionâ for âŁcracked ceramic or flaking coatings âand electrical âchecksâ that â˘compare⣠measured continuity and resistance âŁto the⣠manufacturer’s reference values for theâ assembly.
Whenâ replacing âthe âignitor, verify⣠that⤠the â˘replacement matches the oven’s connector type, mounting orientationandâ electrical rating before⢠installation; the WB13T10045 GE Oven Ignitor Assembly⤠must be mechanically and⣠electrically compatible with the oven’s harness and⤠gasâ valve. Follow safeâ workâ practices: isolate electrical power (and gas âsupply if applicable),â confirm control calls for heat while measuring the circuit, âand inspect the harness âand gas⣠valve for correct⣠operation⢠after installation. if⣠wiringâ is brittle, connectors â¤areâ corrodedor the gas âvalve does not seeâ appropriate current â˘when the ignitor isâ glowing, replace or ârepair thoseâ components rather than only swapping the ignitor⤠to avoid repeat failures.
- Disconnect power to the appliance â˘and, where applicable, shut off theâ gas supply.
- Remove the ovenâ floor or access â˘panel to reach the⤠ignitor assembly; note mounting and wire routing.
- Disconnect the ignitor harness andâ removeâ mounting screws; transfer â¤any brackets to the new assemblyâ if required.
- Install the new ignitor, route wiresâ as originalandâ tighten âŁfasteners to avoid stress on⣠the element.
- Restoreâ power â(and gas), call for heat, observe a steady incandescent glowand⢠confirm the burner lights within the normalâ ignition interval.
- Perform a final check on insulation,â connector securityandâ proper oven operation across a âshort bake cycle.

Q&A
What âis the WB13T10045 â˘and what âdoes it do?
The âŁWB13T10045 is a⣠GE OEM hot-surface ignitor assembly â¤for gas ovens and ranges. It heats to aâ high temperature (glows) to ignite the oven’s gas burner. The â˘oven control senses the â¤ignitor and the gas valve opens only when âthe ignitor draws sufficient current or reaches the required temperature.
How âdo I know⣠if theâ ignitor is bad?
Common symptoms are the oven not heating, âvery long preheat âtimes, âthe ignitor not glowingor the ignitor glowing âbut the burner not lighting. Aâ weak⢠ignitor can glowâ but⢠not draw enough âcurrent to open the gas valve. Also inspect for visible cracks or damage â¤to the ceramic/glass element.
How â˘canâ I âtest theâ WB13T10045⣠ignitor?
First, disconnect power. Use a multimeter to check continuity/resistance âacross the ignitor terminals; a healthy hot-surface ignitor usually shows a â¤low⤠resistance â(typical âŁrangesâ vary by model, frequently⢠enough roughly 40-300â ohms – check OEM specs). An open circuit (infinite resistance) meansâ it’s failed.⣠For a live â˘test (qualified tech âonly), measure the â¤current draw with a clamp â˘meter while the oven attempts to ignite; many âignitors need to â¤draw around 2.5-3.5 âA on a â120V circuit to open the gas valve -â significantly lower current suggests replacement.
Can I replace âthe WB13T10045 myself? What safety steps should I take?
Yes, many competent DIYers â˘can replace it, but follow safety steps: âdisconnect electric power at âthe â¤breaker (this is most âsignificant),â turn off the⣠gas supply as a precaution, âŁallow the oven â¤to cooland avoid touching the ignitor’s glass/ceramic âsurface. Useâ insulated toolsâ andâ wear gloves/eye protection. If you’re â¤not comfortable withâ gas âor electrical work, hire a qualifiedâ technician.
What tools and parts âdo I need to âreplace the ignitor?
Typical tools: screwdriver or nut driver set, possibly⤠aâ socket set,â needle-noseâ pliersand a multimeter for testing. You may also want a âclamp meter âfor current testing. You’ll⣠need the replacement âWB13T10045 ignitor and, ifâ your oven’s connector âŁis damaged, replacement wire connectors. Keep replacement hardware (screws/bracket) handy if the old ones are corroded.
How long⢠does replacement âtake and are there common âinstallation pitfalls?
Replacement usually takes 15-45 minutes depending on âmodel â˘and access. Common pitfalls: not cutting power, touching or cracking the ignitor element â(it’s⤠fragile), âimproper seating/alignment of the ignitor with â¤the burnerand loose⤠electrical â¤connections. Make sure the ignitor is securely mounted and that the wire terminalsâ are fully engaged.
Is WB13T10045⤠compatible with my âŁGE oven model?
WB13T10045 is an OEM⤠GE â˘part âused in many GE gas ovens and ranges, butâ compatibility varies. Confirm fit âby checking your appliance model ânumber (from the appliance rating plate) against the part âlisting or âGE â¤parts lookup. If unsure, provide your âoven model and serial to a parts â¤dealer or technician to verifyâ compatibility.
Could a failed âignitor be mistaken for âothre problems?
Yes. Similar âsymptoms âŁcan come from a faulty gas valve, oven control board, thermostat, safety valveor wiring/connectors. â¤If the ignitor tests good⤠(proper resistance and current draw) but the burnerâ still won’t light, further âdiagnosis of theâ gas valve or⤠control circuitry is needed. When in â˘doubt, consult a qualified appliance technician.
