WB13T10045 GE Oven Ignitor Assembly â¤is a hot-surface ignitor assembly used in âŁGEâ gas ovens and ranges;⤠it⤠isâ an electrical⤠heating element mounted â¤in a bracket with a connector and insulation that glows hot enoughâ to⣠ignite the â¤oven’s burner â¤gas whenâ energized. As a replaceable appliance component, the assembly is âtypically constructed from a high-resistance ceramic or silicon⣠carbide âheating â˘element housed in a metal mountingâ that positions the⤠ignitorâ adjacent to⢠theâ burnerâ ports and provides a standard electricalâ interface to âthe oven harness.
Insideâ theâ appliance the⢠ignitor’s role is âto convert⣠electrical energy into thermal energy during the ignition sequence: when the oven control calls for âheat itâ supplies voltage to⣠the ignitor,⣠the element⢠heats⤠toâ a visible glow and âŁdraws âŁthe designed current âwhich, in turn, allows theâ gas safetyâ valve to open and⤠the burner to light.â the component âthus interacts directly with the âoven control board or thermostat,â the gas safety valve(s), âŁthe burner assemblyand âthe wiring harness; its electrical characteristics â(resistance and âcurrent draw), mounting â˘location, âand thermal response are critical to⢠timedâ ignition, âflame stability, âand safetyâ interlock behavior inâ the âgas ignition system.
In the following article⤠you will â¤findâ a technical examinationâ of â˘the WB13T10045 âGE⤠Oven Ignitor âAssemblyâ covering⢠its function and âŁtypical specifications, compatibility⣠considerations and how to verify correct âreplacement, â¤common âfailure âsymptoms and diagnostic indicators, â˘recommended troubleshooting checks such as resistance and⢠voltage measurements â¤and visual inspection pointsand practical⤠replacement considerationsâ includingâ physical fit, connectorâ type and electricalâ characteristics.

Function âand Roleâ of⢠the Oven âIgnitor in Gas Valve Actuation and Heat Regulation
The WB13T10045 GE âOven Ignitor Assembly is a hot-surface ignitor â˘that⢠provides the thermal emission and âŁelectrical load required to actuate âŁthe oven gas safety âvalve. As the ignitor âheats toâ its operatingâ temperature it âdraws notable current from⤠the oven’s âsupply; the gas valve⣠is designed to open â˘only when that currentâ indicates â¤the ignitorâ has reached â˘sufficient temperature and electron emission.â Proper replacement requires matching the ignitor’s electrical⣠rating, connector typeand mounting âso the valve âsees the same current/time profile during the preheat cycle.
Technically, failures⣠occur when the ignitorâ no longer reaches the ârequiredâ surface temperature or draws⤠insufficientâ current even if it glows, which⤠prevents valve⤠actuation or produces long⢠ignition delays.⢠Common practicalâ indicators include a glow that â˘is noticeably dim, extended âpreheat âŁtimesor an oven that clicks but⣠never lights. Simple, safe bench checks âsuch as âŁmeasuringâ cold resistance â¤with âpower removedâ and observing the glow during aâ controlledâ preheat canâ help differentiate an ignitor fault from a faultyâ gas valve âor⤠control circuit; low â˘cold-resistance continuity â˘with reduced hot current â¤implies degradation of the â˘element and supports⤠replacement with a compatible unit such as the âWB13T10045. For field diagnostics, technicians typically verify continuity, compare measured values âto âthe appliance service data, âand confirm connector/mount compatibility before installing âa replacement.
- Symptoms: dim â˘glow, delayed ignition, noâ ignition despite â¤clicking â¤or gas flow detection.
- Safe⤠checks: visual⤠glow inspection, cold-resistance â˘continuity with power off, verify correct connector andâ mounting⣠alignment.
- When to replace: persistent low current âdraw âunder normalâ preheat or erratic behavior after confirming wiring and⤠control outputs.

How the âWB13T10045â GE Oven Ignitor Assembly âWorks Inside âthe Appliance: Electrical â˘Characteristics, Thermal Ignition âProcess, â˘and Control Integration
The WB13T10045 GE Ovenâ Ignitor Assembly is a âresistive âheating element that âfunctions as â¤a hot-surface ignitor â˘in gas âŁoven systems. electrically, it is âa low-voltageâ drop incandescent element driven⣠by the appliance control board on the appliance mains âsupply; the âcontrol supplies⤠line âvoltage to⣠the ignitorâ until the element reaches the required glow temperature and the control permits the⢠gas safetyâ valve âŁto open.The ignitor⤠behaves as a simple⤠resistiveâ load whose cold-to-hot resistance changes noticeably during warm-upand manny âcontrol boards rely on âtheâ expected âcurrent draw or⤠a timed preheat interval to determine when to enable the⢠valve. For compatibility and⢠safe⢠replacement, technicians must match the assembly’s connector type, âŁmounting âfootprintand electrical characteristics to the oven’s control⤠strategyâ rather than ârelying solely on visual similarity.
- Typical checks: verify continuity âwith a multimeter, observe a steady incandescent glow âŁduring âpreheatand confirm âŁthe control supplies âmains⣠voltage to the ignitor during a light â˘cycle.
- Failure symptoms: no glow â(open circuit), a visibly weak glow⢠(reduced emission or higher hot resistance)or intermittent⣠operation â¤leading to repeated valve click/no flame cycles.
- Replacement guidance: match connector⤠pinout⣠and mountingandâ ensure⢠the âreplacement element producesâ the same thermal response time so the control’s timing â¤andâ safety thresholdâ remain valid.

|---|---|
| Function | resistive heating element that reaches incandescent temperature to ignite gasâ at burner ports |
| Control interface | Driven⤠by the oven control on âline voltage;â the control sequences power âand monitors current or time âbefore opening theâ gas valve |
| Commonâ failure⣠modes | Open circuit, reducedâ emission (age-related âcoating/cracking), physical damage toâ mounting or terminals |
Thermally, the ignitor converts electrical⢠power into â˘radiant⤠heat; as⣠the surface temperature rises, âemitted infrared energy ignites the gas mixture when the valve opens. The thermal ignition process dependsâ on both surface temperature âand exposure to the burner ports-restrictedâ airflow or carbon buildup⣠can reduce emitted heat and prevent reliable ignition even⣠if â¤theâ elementâ glows. in practical âŁservice diagnostics,record whetherâ theâ ignitor reaches a âshining orange glow âwithin the expected preheat interval and whether the âŁcontrol completes its safety checks before â˘energizing the valve. If⢠the element â˘glows but theâ oven â˘still fails to light, inspect valve function and âburner orifices; if âŁthe element fails to achieve proper glow or shows an open circuit, replacementâ with a matching âWB13T10045 GE Oven ignitor Assembly (or âŁanâ approved equivalent) isâ the correct corrective action.
Common âŁFailure Symptoms: Intermittent⢠Ignition, Prolonged âglowand Electricalâ Fault Indicators
The⤠WB13T10045 GE Oven⤠Ignitor Assembly is a hot-surface ignitor⣠that heats to the âŁtemperatureâ needed âto allow the oven âgas âvalve to⢠open and sustain⤠combustion. Its â¤primary failure â¤modes are increases in⣠element resistance and⤠mechanical damage to the ceramic or filament, âŁwhichâ change the heating â¤profile of the element. When the element âno longer drawsâ the intended currentâ or⢠shows âuneven heating, the valve timing â˘and ionization âconditions can âbe marginal, producing â¤the intermittent ignition âandâ prolonged âglow symptomsâ commonlyâ encountered during routine operation.
- Intermittent⤠ignition: oven lights inconsistently from cycle to cycle.
- Prolonged glow: ignitor⣠glowsâ for an extended⣠timeâ before gas flow starts.
- Open circuit or abnormally highâ resistance âŁon multimeter.
- Visible cracks, pitting,⤠or uneven glow pattern onâ the element.
- Normal spark or control activity but no valve actuation⤠(possible low-current condition).
Technicians⢠separate⣠ignitor âfaults from control or valve issues by simple electrical⤠and visual checks:â measureâ the element’s resistance âand observe glow time under â¤a controlled âtest cycle.â A degrading ignitor typically shows rising resistanceâ or inconsistent glow intensity; â˘an open reading confirms⤠failure.â If â˘resistance andâ glow are within expected ranges âŁbut the valve does not⢠open, âthe â¤fault â˘shifts to wiring, the safety gas â¤valve, âor the oven⢠control âmodule. âFor compatibility,confirm⢠that âŁthe WB13T10045 assembly matches the oven’s âmounting,connector â˘type,and electrical ratings before⢠replacementâ to ensure correct interchangeability and restore reliable âignition behavior.
| Item | Description |
|---|---|
| Coldâ resistance | Tens to a few âhundredâ ohms; âan open or dramatically higher value indicates a failed element |
| Typical âglow⤠time | Usually âa âfew seconds âbefore the gas valve âopens; considerably longer⤠glow suggests reduced heating â˘performance |
Troubleshootingâ and â˘Diagnostics: Resistance Measurements, Isolation Testsand âStep-by-Step Fault âIdentification
The WB13T10045 GE âOven Ignitor Assembly is a resistive glow element whose primary failureâ modes are filament⣠open-circuit âand insulation âŁleakage. To diagnose it, remove the assembly and use a digital âmultimeter to check resistance across the ignitor terminals; a⢠reading of âinfiniteâ resistance (OL) indicates a⤠broken element, while a âŁnear-zero reading indicatesâ a â˘short.â Before any measurements, disconnect electrical power âŁand⢠close the gas supply to prevent shock or⣠an unsafe ignition event.Visual inspection â¤for cracks in the ceramic and discoloration âof the element can corroborate electrical findings:â a visibly damaged glow bar⢠combined â¤with âan open reading⤠is a clear replacement indication, while discoloration aloneâ may indicate age-related degradation âŁbut not necessarily open âcircuit.
Isolation testing complements resistance checks byâ detecting⣠leakage from⢠the element âto the chassis. Use âa low-voltage insulationâ tester or⣠a megohmmeter (typical âbench threshold: >1 MΊ acceptable) â¤to measure resistance from the ignitor body âŁto ground; significantly lower values indicate⣠moisture or coating breakdownâ and ârequire⣠replacement. Forâ stepwise faultâ identification,â perform continuity⢠and insulation⢠testsâ first, then verify that âthe oven controllerâ supplies⣠the â¤correct line voltage during â˘a call â˘for heat; if the controller provides correctâ voltage but⣠the âŁelement does notâ glow or draws insufficient âcurrent,â replace the ignitor. Practical examples: an⢠ignitor that shows â¤normal cold resistance âŁbut fails to â¤glow under voltage often has internal microcracksâ or degraded emission âcharacteristics âand should be âreplaced rather âŁthan repaired.
- Disconnect power and gas, âremove ignitor assembly from oven.
- Measure â˘resistance across terminals with DMM; note OL (open) or unusually â¤low resistance.
- Perform⤠insulation â˘test â¤from element body to chassisâ (expect high⤠megohm values).
- Reinstall âand verify controller â˘voltage duringâ a test cycle; observe glow â˘time and⢠current âdraw â˘if possible.
| Item | description |
|---|---|
| Continuity | Open reading indicates âbroken filament; any âdefinitive â¤open requires replacement. |
| Highâ resistance | Resistance significantlyâ above manufacturer specification suggests â¤element degradationâ and reduced current draw under load. |
| insulation resistance | Low resistance to âchassis indicates leakage orâ contamination; values should be in the megohm ârange. |
Q&A
What âis the WB13T10045 and what does it do inâ my GE gas oven?
The WB13T10045 is a hot-surface (glow-bar) oven ignitor used on many GE gas â¤ovens and ranges. When the âovenâ calls âfor heat, theâ oven âcontrol sends line voltage⣠to the âignitor which glows hot and âdraws current. The hot ignitor âŁheats enough to open the gas⢠safety valve âand allow burners to âlight. Without âa working ignitor the gas⤠valve will not â˘open and the burner will â¤not light.
What are âŁcommon symptomsâ that âthe WB13T10045 ignitor⤠is âŁfailing?
Common⤠signs include the oven not heating or taking a long time â˘to light, theâ ignitor glowing weakly â¤or â˘not at all,⢠long preheat times (frequently enough >90â seconds)or the â¤oven â˘cycling âwithout âmaintaining temperature. A non-continuous or open ignitor⣠willâ prevent the gas âvalve from opening.
How can I testâ the âŁWB13T10045â ignitor to see if it’s bad?
First, disconnect power and remove the ignitor soâ you can âaccessâ its terminals. âWith⢠the ignitor disconnected, use a âdigital âŁmultimeter set⤠to ohms/continuity. A reading of infinite/OL indicates an open (failed) element.A finite low-to-moderate⤠resistance usually indicates continuity.â Visual inspection for cracks or a â¤damaged element âalso helps.â For a live test⣠(only âif you are qualified), measureâ whetherâ the ignitor glows when âthe âoven calls for âŁheat and whether⣠it⢠draws the expected current per the oven’s⤠service data-if it glows âbut is⢠weakâ and does not⢠draw sufficient⤠currentâ the gas valve⤠may⤠not open âŁand⢠the ignitor âshould be replaced. If youâ are not experienced with live electrical tests, âstop and consult a technician.
Can âI âreplace the â¤WB13T10045⢠myselfand â¤whatâ safety⤠steps should I⢠follow?
Many â¤homeowners âwith basic mechanical â¤skills can replace theâ ignitor, âbut you mustâ follow safety steps:â turn off electrical power⢠to the range at the breaker,â shut â¤the gas supplyâ off atâ the valve,⤠and allow components to cool. Wear gloves to protect the â˘fragile ignitor elementâ (avoid touching âthe ceramic/glow surface â¤with bare hands). disconnect wiring, âremove mountingâ screws,⤠install the new â¤ignitor, âreconnect wiring, restore âpower⢠and gasand â˘test. If you are uncomfortable working with gas or live âelectrical connections, hire a qualified applianceâ technician.
What tools and â˘parts do I âneed to âreplace the WB13T10045?
Typical tools: screwdriver or nut driver set (usually â¤1/4″ âor 5/16″), pliers, âand â¤a work light. You may also⢠need a multimeter to verify the old part is bad.⢠Parts: âtheâ replacement ignitor âŁ(WB13T10045 or an â˘exact âŁOEM equivalent for your model),â and any new mounting screws or wire connectors if the originalsâ are damaged.Always â¤verify compatibility âŁwithâ your âoven model number before purchasing.
Is WB13T10045 compatible with âmy GE oven model?
Compatibility⣠depends on theâ specific GE model.â WB13T10045â is a common OEM ignitor used on many GE andâ Hotpoint ovens, but you should confirm⢠compatibility by⤠checking theâ appliance model number â(usually on âaâ tag behind the oven door âor on the frame) and cross-referencing that model with GE parts lists or âa â¤reputable partsâ supplier. Using the exact OEM part number or an approved equivalent â˘ensures⢠proper â¤fit and⣠operation.
Howâ long does the⢠WB13T10045 ignitor lastand what affects its lifespan?
Typical ignitor life varies but commonly⣠ranges from⤠several years to over a decade âdepending on âuse, power cyclingand⣠operating conditions.Frequent on/off cycles, voltage spikes, moistureor mechanical damage shorten lifespan.Regularly inspect for cracks andâ proper glow behavior; replacing at theâ first signs of âŁweakening prevents longer preheatsâ and no-heat conditions.
Will replacing the ignitor⣠always fix an oven that won’t heat?
Not always. A failedâ ignitor is a commonâ cause âof âno-heat, butâ other issues can prevent ignition: a âŁfaulty⣠oven control board, gas safetyâ valve, wiring/connectorsor a gas supply problem. If⣠the new ignitor glows properly but the burner⢠still won’t light, â˘further âdiagnosis of the gas⤠valve, electrical supplyand⢠control circuitry will âŁbe necessary-consider hiring a technician for⣠those⣠tests.
Wrapping Up
The WB13T10045â GEâ oven Ignitor Assembly playsâ a central role in an oven’s ignition system by providing the heat necessary⣠to initiateâ and â¤sustain burner operation.⣠As a âkey⣠component that directly affectsâ ignition timing, temperature â˘consistency and overall cooking performance, âa properly functioning ignitor contributes to energy efficiency, reliable âŁbake and broilâ resultsand safe applianceâ operation.
Accurate diagnosis is âsignificant because symptoms such as slow⤠orâ no ignition, extended preheat timesor intermittent⢠heating can arise âfrom multiple â¤causes.
