WB13T10045 âGE Oven Ignitor âAssembly is a hot-surface ignitionâ component used inâ many GE gas ovens and â¤ranges.The assembly typically â¤consists â˘of a⢠ceramic âor glass-encased igniter â¤(glow âŁbar) mounted â¤with a bracket and an âelectrical connector; it is designed to convert electrical energy âinto radiant heat⣠to ignite â¤burner âgas.As a⣠replaceable service âpart, it is indeedâ categorized as an oven⣠ignitor assembly rather than a gas valve or control module.
within the⣠appliance, the ignitor’s role is to heat rapidly to a high temperature when theâ oven âcontrol initiates a bake or broil cycle â¤so âŁthat incoming⢠gas can be ignited safely and reliably. The ignitor⤠interfaces âelectrically with the oven control â˘board âand the gas safety valveand mechanically with the burnerâ assembly andâ mountingâ hardware. In typical operation the ignitor must⢠reach its⣠operating temperature before the âŁgas valve is allowed to openâ or remain energized; if⣠the ignitor failsâ to reach the required temperature the valve will not supply gas, resulting in âno ignition. As of this interaction with the control and gas delivery systems,the ignitor is critical âboth for functional heating and for safe ignition sequencing in gas appliances.
In this⣠article readers will find a technical overview âof how âthe WB13T10045 ignitor functions, guidance on model and compatibility considerations, common failure symptoms â¤to recognize (for⤠example no heat, prolonged glow without â¤ignition, â¤or intermittent âoperation)and step-by-step troubleshooting⤠methods suitable âfor âŁa technician or experienced appliance âowner.The article âalso covers practical replacement considerations – matching connector typeâ and mounting configuration, basic electrical checks (visual inspection, continuity/resistance and voltage⤠verification)and safety precautions to take before servicing gas âand electrical components.

Function and Role⤠of the Oven Ignitor Assembly:â Thermal Ignition, Gasâ Valve Actuationand Safety integration
The WB13T10045â GE Oven Ignitor Assembly is a glow-bar style ignitor that âprovides thermal ignition by converting electrical energy⣠into heat until the element reaches a temperature sufficient to initiate gas flow âŁand combustion. The âignitor’s electrical characteristics change âas it heats: â˘its cold element draws a relatively high currentand as the element reaches⣠operating âtemperature its resistance rises and âthe current falls.â Oven âŁcontrol electronics or a gas valve module monitor âŁthatâ change in current (or the⤠steady-state hot âŁresistance) as the permissive signal to energize⣠the gas valve; â˘only after the ignitor⢠has achieved⣠the requiredâ thermalâ state⣠will the valve âbe allowed â˘toâ open. In practice this means a visible steady⣠orange-red glow should appear⤠before gas âis released-if âthe glow remains weak or takesâ unusually long, the control may withhold the valve signal to prevent unignited gas flow.
Theâ ignitor is an integral part of â¤the appliance⤠safety âchain and must be compatible with the oven’s control logic and connector⢠styleâ to perform reliably. A degraded or intermittentlyâ failing ignitor âproducesâ common symptoms such as extended preheat times, repeated â¤ignition attemptsor a complete âfailure to light; these symptomsâ areâ typically resolved⢠by replacingâ the ignitor rather than adjusting gas components. Technicians frequently verify ignitor condition by observing â˘glow behavior, measuring continuity/hot resistanceand checking that the control sees the expected change in⣠current beforeâ the gas valveâ is powered. Practical âinstallation notes:â ensure the WB13T10045 mating connector and mounting orientation match the oven model, tighten electrical âconnections to avoid voltage dropand follow⣠theâ manufacturer’s sequence for restoring âpower and testing ignition to confirm the safety interlock and valve actuation operate correctly.
- Thermal mechanism:â glow-bar heats to permit safe gas âflow.
- Actuation signal:⣠control monitors⣠current/resistance change to⤠open the gasâ valve.
- Safety⤠role: prevents gas â¤release until⢠a âŁhot ignitor âis âconfirmed.
- Common symptom: long glow period orâ no â˘ignition indicates weak/failed ignitor.

How the WB13T10045 GE Oven Ignitorâ Assembly Works Inside the Appliance: Electrical Characteristics, Thermal â˘Responseand Control Interfaces
The WB13T10045 GE Oven Ignitor Assembly is a hot-surface ignitor âused⣠to â¤initiate gas flowâ by heating to a visible orange glow and allowing âthe oven’s gas safety valveâ to âŁopen.Electrically, the ignitor is a resistive element designed for 120 VAC operation; its cold âŁresistance is in the â˘low tens of⢠ohms and the element â¤draws severalâ amps whenâ energized, â˘producing the thermal power necessary âforâ ignition. The control path includes the oven control board⤠and the âsafety gas valve coil: the board supplies line⣠voltageâ to the ignitor during a callâ for âŁheat and monitors current/voltage to confirm⤠a functioning glow.⣠Practical⢠compatibility requires matching the assembly’s mounting, terminal style â(usually two spade connectors)and electrical ratings to âthe⣠appliance⣠model-replacing withâ a physically similarâ part that has differentâ resistance or current draw can prevent the gas valve from opening or⣠cause safety interlocks to inhibit âŁignition.
- Electrical behavior: âresistive glow element that heatsâ rapidly and lowers resistanceâ as it âreaches operating temperature.
- Thermal response:⢠reaches ignition temperature in tens of⣠seconds under normal supply voltage.
- Control interfaces: oven control âboard, âŁsafety gas valveand door/thermostat interlocks; some boardsâ monitor ignitor current for âdiagnostics.
- Common â¤diagnostics: long glow time, no glow,â or open-circuit resistance indicate replacement; check wiring and connector continuity before⢠replacing.
| Item | Description |
|---|---|
| Function | Convert electrical energy to heat to ignite the oven⣠burner by allowing sufficient current to the gas valve. |
| Typical behavior | Rapid âŁwarm-up to visible glow; resistance âfallsâ as temperature âŁrises; draws steady current while energized. |
| Common failure signs | Oven fails to light, extended preheat time, visibleâ cracking or reduced â¤glow; verify connectors and control⤠output before â¤replacing. |
Thermally, the assembly behaves like â˘a ceramic or silicon-carbide glow-bar⣠that⤠mustâ reach a âŁstable high temperature âto ensure reliable ignition; any surface damage,â contaminationor mechanical âŁstress changes⢠the heat-up â¤curve and reduces radiant output. Control systems useâ eitherâ a â¤timed valve sequence or liveâ current sensing: some âŁboards only permit the gas valveâ to open after theâ ignitor draws the expected currentâ for a set interval, so a weak âignitor that heats more slowly or draws âless current can prevent ignition even â¤if it glows visibly. Forâ practical troubleshooting, a technician should measure cold resistance, verify that theâ controlâ board⤠supplies line voltage during a⣠call for heatand⣠observeâ glow time; if the ignitor passes wiring⣠and voltage checks but shows reduced glow or long warm-up, replacing âthe WB13T10045 GE â˘Oven Ignitor Assembly âwith a âmatching-rated âŁunit is the correct⢠remedial⣠action.
Common⣠Failure Symptoms and Diagnostic Indicators: No Glow, Delayed Ignition, Erratic⢠Heatingand Related âŁError Codes
The WB13T10045 GE âOven Ignitor Assembly â˘is âŁaâ hot-surface âignitor designed to heat to a specific temperature and draw â¤sufficient current so the gas valve opens and combustion starts. In service thisâ component should glow luminous orange within seconds of receiving⢠power; failure modes âinclude no glow (open/failed element or connector fault), faint or delayed glow (age-related degradation or wrong part resistance),⤠and âintermittent operation that causes erratic âheating.Compatibility issues âarise when an ignitor with incorrect electrical characteristics is fitted-an assembly that draws too little current â˘will not activate the⢠gas valve evenâ ifâ it shows continuity, so matching the replacement ignitor to the oven’s electrical and mounting specifications is âcritical for reliable ignition and regulation of oven temperature.
- No âŁvisible glow on call-for-heat: indicates open circuit,connector/cable damage,or complete â˘element failure; verify supply to⤠the ignitor and continuity at connectors.
- Delayed ignition or âpuffâ at lighting: âoftenâ due â¤to weak heating element that reaches operatingâ temperature too slowly; âmeasure current âdraw⢠under power and compare⣠to expected behavior âor⤠replace with the correct⤠assembly.
- Erratic⣠heating or cycling: can result from âintermittent ignitor contact, thermal degradationor downstream control board interpreting failed ignition-inspect⣠terminals, â˘harnessand control error history.
- Control panel⤠error codes related to âŁignition or sensorâ faults: these typically point to failed ignition attempts or open/shorted â˘sensors; consult the oven’s service manual forâ code definitions â˘and sequence diagnostics.
Technicians diagnose these symptoms using a combination of visual inspection, â¤electrical checksand functional tests: âŁverify proper supply voltage to the â˘ignitor circuit, confirm⢠continuity and secure terminalsand observe the ignitor under aâ controlled call-for-heat for time-to-glow âand steady âŁbrightness.â Aâ practical example:⣠if the ignitor glows faintly⤠but âtheâ gas valve does not open,â the âignitor has likely lost its â˘required filament conductivity⤠and â˘should âbe replaced⢠rather than relying⤠on intermittent operation; installing a⤠correctly specified âWB13T10045 GE â˘Oven Ignitor⢠Assembly restores proper currentâ draw and ignition timing whenâ the restâ ofâ the⤠gasâ control system⢠is known good.

Q&A
What is the WB13T10045 ignitor assembly?
The WB13T10045 is a hot-surface â(glow-bar)â ignitor assembly used in many âGE gas ovens and ranges.It heatsâ to⤠a high temperature, âŁdraws currentand causes the oven’s gas safety valve to open âso gas â¤can flow and âignite. Itâ is ânot a spark igniter-it’s a continuous-glow type usedâ for⣠main oven âburners.
What are âthe common symptoms that the WB13T10045 is failing?
Typical symptoms include:â the oven taking much longerâ than normal toâ ignite,the burner never lighting even though the â¤ignitor glows,the⣠oven not⣠reaching temperature,or the ignitor glowing â˘weakly (dim). A completely open or cracked ceramic/glass element or visible âburn damage alsoâ indicates failure. If you smell gas, shut the appliance off⢠and⣠ventilate âthe âŁarea before investigating-do⤠not â˘attempt ârepairs with an active gas leak.
