WB13T10045⤠GE oven Ignitor Assembly is a hot-surface ignitorâ (glow-bar style igniter) designed for use in gas range and wall⤠ovenâ bake/broil systems. As an ignitor⤠assembly, it consists of a high-resistance ceramic-glass element and associated mounting and electrical connectors intended⢠too â˘replace or repair the original equipment manufacturer (OEM) ignitor on⤠compatible GE appliances.
Within the appliance, the ignitor’s role is to⢠provide the thermal and electrical condition ârequired by⢠the oven’s gas safety circuit⣠to open the gas valve and light the burner. âWhen energized, theâ ignitor heats to a visible glow; that heating producesâ the current draw and temperature profile the control⣠and safety âŁvalve circuitry expect before the gas valve is permitted to⤠open.â The component thus interfaces with the oven⣠control board, the gas safety valve, the burner/manifold assemblyand the â˘oven wiringâ harnessand it is indeed typically mounted adjacent to the bake or broil burner inâ the oven cavity.
This article will explain âthe ignitor’s operating âprinciple â˘and how the WB13T10045 integrates â¤withâ gas⤠ignition and âsafety systems, summarize model compatibilityâ and fitment considerations, list commonâ failure symptoms (for example, no ignition, extended glow timeor weak/no glow)andâ outline diagnostic topics a technician or informed âappliance owner⢠should consider-such as visual inspection,⤠continuity/resistance checksand⣠verifying ârelated wiring and â˘control⤠signals. It will also⤠cover practical replacement considerations including â¤mounting, connector typesand safety precautions to â˘observeâ during inspection and service.

Function and â˘Role of the Oven Ignitor⣠in GE Gas Oven Combustion Control
The WB13T10045â GE âOven Ignitor Assembly is â¤a hot-surface â(glow)â ignitor that provides the thermal and electrical behavior the oven control⤠uses to manage burner ignition. When the⤠control board applies mains voltage (typically 110-120 VAC) the ceramic/glass-coatedâ element⣠heats to âŁa glowing temperature;⣠as⤠it⤠warms its resistance rises and the current through the circuit falls. âŁThe controller senses that change in current or the elapsedâ warm-up time âŁand then permits the safety gasâ valve to open so⣠the released gas can be ignited â˘by the glowing â¤element,which prevents gas flow until ignition conditions âare present.
From a practical âŁtroubleshooting and⣠compatibility âoutlook, the ignitor serves both as the energy⤠source for ignition â¤and as a timing/feedback component for combustion control. A weakenedâ element that glows dimly or takes too long to reach operating temperature will delay valve opening or prevent ignition entirely, causing repeated ignition attempts or noâ flame.Technicians typically verify correct operation byâ observing glow time, â˘checking cold resistance with a multimeterand confirming proper connector andâ mounting fit before installing a replacement ignitor to âŁmaintain expected thermal and electrical response.
- Common symptoms of a failing âŁignitor: slow glow, no glow, extended preheat time, repeated ignition cyclesor failure of the valve to open.

How the WB13T10045 â˘GE Oven Ignitor Assembly Works Within âthe Oven Ignition and Safety Circuit
The WB13T10045 GEâ Oven Ignitor Assemblyâ is aâ glow-bar style ignitor that functions as the primary heating element in the âoven’s⢠ignition and safety circuit. When the âoven control sends voltage, the ignitor begins to⢠heat and glow; as it reaches âoperating temperature its resistance changes and it âpermits the several amps of⤠current required to energize theâ gas âsafety â¤valve.The safety valve is designed not âto open until the ignitor is drawing sufficient current, so the ignitor both initiates ignition and acts as â¤a current-sensing interlock that prevents raw gas flow when the flame source âis absent or weak.
- Typical behavior: visible orange glow during warm-up, delay of several⣠seconds before gas valve opens
- Failure âmodes: no glow (open/failed â¤filament), glowâ but no ignition (insufficient current draw), intermittent cycling (poor connectorâ or âdegrading element)
- Replacement considerations: match â˘electrical characteristics,â mounting bracket, âŁandâ connector type to ensure proper integration with the oven control and valve
In âŁpractical service, technicians verify ignitor â¤function by observing the glow, measuring current in the ignition circuitor â˘checking continuity â˘and comparative resistance to known-good values;⢠a âweak ignitor may still glowâ yet fail to⢠pull the â˘required current, whichâ prevents the safety valve from actuating. Compatibility isâ mechanical and electrical-an appropriate replacement must replicate the original assembly’s wattage âand connector configuration so the oven⣠control’s timedâ ignition âsequence and safety interlocks operate as designed. For example, a replacement âthat physically fits but has âŁhigherâ resistance will slow warm-up and cause repeated ignition timeouts, while âincorrect mounting âcan change the ignitor-to-burner alignment and â˘produce unreliable ignition.
| Item | Description |
|---|---|
| Function | Heat element that âenables current flow to the gas safety valve and providesâ a safety interlock |
| Operational signal | Visible glow followed by â˘sufficient current âdraw to allow valve âactuation |
| Compatibility notes | Must match âŁmounting, â¤connector, âand electrical characteristics of the oven control and âvalve |
Common Failure Symptoms and Diagnostic Indicators of Ignitor Degradation
The WB13T10045â GE Oven Ignitor â˘Assembly is a hot-surface ignitor whose primary function is to draw enough current when heated to⢠allow the gas safety valve to open and the burner âŁto light.â Degradation manifests as âreduced emission of infrared energy from the ignitor element: the âelement may still âglowâ faintly⤠but⢠no longer reaches the temperatureâ required forâ the valve to operate. Compatibility considerations include âŁmatching the physical mounting, connector â˘type, âŁand electrical characteristics (resistance and current draw)â to the oven’s control and⢠valve assembly; replacing a âfailed unit with one that differs âin these parameters can restore visual glow without producing sufficient âcurrentâ to open the gas valve, producing a misleading symptom âof “glowing but not âlighting.” âPractical examples include ovens that take excessively long to preheat, cycle â˘repeatedly without maintainingâ flameor produce repeated clicking⣠from âthe control while the ignitor fails to sustain ignition.
Technicians diagnose ignitorâ degradation using both visual and electrical checks: inspect the element for â˘cracks, scaleor darkened spots and â¤measure resistance or continuity with power⢠removed.â A wholly open circuit or a resistance âŁconsiderably outside the manufacturer’s specification⢠indicates a failed element;â conversely, âŁa âŁlow but marginal resistance paired with a dim glow under powered conditions suggests reduced âemissivity and inadequate current draw to actuate the gas valve.Functionalâ diagnostics include observing preheat time and whether the âcontrol⢠attempts to open the valve while âthe âŁelement reaches full glow; if the element glows yet no gas flows, the ignitor’s emitted energy or current⢠is âŁinsufficient and replacement with a â˘correctly⢠rated WB13T10045 or OEM-equivalent unit âis warranted. For safety, âalways disconnect electrical power and gas supply before performing⢠electrical measurements or component replacement.
- Oven fails⢠to reach set⢠temperature or long preheat times.
- Ignitor does not glow, glows dimlyor shows visible cracks.
- Repeated âcontrol clicking or cycling without sustained flame.
- Multimeter showsâ open circuit âor resistance outside the part’s⢠specification.
| Item | Description |
|---|---|
| Visual âŁcondition | Cracks, darkeningor uneven glow indicate element âdeterioration. |
| Electrical âresistance | Open circuit or resistance far from OEM spec indicates failure or degradation. |
| Current âbehavior | Dim glow with no⤠gasâ flow indicates insufficient current to operate the safety valve. |
| Functional symptom | Extended preheat,⤠cyclingor intermittent ignition point to progressive loss ofâ emissivity. |
Replacement Considerations, Installation âProcedure⤠and Post-Installation⢠Troubleshooting for WB13T10045 GE oven Ignitor Assembly
Theâ WB13T10045 GE⢠Oven âIgnitor Assembly is a resistive hot-surface ignitor that warms to visible glow and draws the current required to allow the oven’s gas valve⤠to open; the element’s electricalâ and⣠thermal behavior directly â¤controls ignition timing and reliability. Functionally, the⤠part is a two-wire, low-voltage heated âelement that must reach its operating temperature andâ present the expected cold and hot â˘resistance ranges to signal correct operation; an ignitor that⢠glows weakly, takes excessive time to⤠glow,⢠or showsâ an open circuit on a multimeter typicallyâ fails to pull the gasâ valve open⤠even though theâ control board and valve might potentially be good. Compatibility considerations include the mounting footprint,wire terminal style,and electrical resistance⢠rating – mismatched geometry or ratingsâ can prevent proper âseating,produce âpoor contact,or alter âwarm-up time,so âtechnicians should confirm model and connector fit for the oven before installation.Practical âexamples include diagnostics⤠where the oven’s burnerâ clicks but does not lightâ (common with⢠a degraded âignitor) and replacement restores â¤normal preheat time when the new unit matches the original assembly’s mechanical and electrical⤠specifications.
For installation and post-install troubleshooting âfollow safe, methodical steps:⣠disconnect power â¤and gas before starting,⣠compare theâ new assembly to â˘the removed part for identical mounting and connectorâ type,⣠and verify continuity⣠and cold resistance⣠with a multimeter prior to assembly. After âmounting andâ reconnecting power, confirm the ignitor achieves a steady, radiant orange glow within the expected warm-up window and thatâ the âgas valve⤠opens when the ignitor is at temperature; if the oven stillâ fails to light, check wiring continuity⤠back to the control board, âinspect the gas⣠valve operationand re-measure resistance – common post-install symptoms include no glow â˘(open or âŁshorted element), âintermittent glow (loose connectionâ or marginal element)or ârapid circuit breaker trips (shortâ in harnessâ or control). If there is a strong gas odor after attempting ignition, shut off power and gas âand ventilate before further diagnostics or calling a qualified technician.
- Power off and lockout, then remove access panel and compare replacement⤠to original.
- Measure cold resistanceâ of the âignitor before installation andâ again â¤after âconnection (typical cold resistance listed below).
- secure mounting hardware and ensure tight,â corrosion-free spade connections;â restore power â˘and âobserve glow and gas valve action⢠during first ignition cycle.
- If ignition fails, verify wiring to the âŁcontrol and⢠check the gas valve coil current draw before replacing additional components.
| Item | Description |

Q&A
What isâ the WB13T10045 andâ what does it do?
The WB13T10045 isâ a hot surface ignitor assembly used in many GE gas ovens and ranges. When the oven calls for heat the ignitor glows hot and draws current; that current allows the gas valve to open and the burner to light.⤠It is⤠indeed not a spark igniter-its âfunction is to heatâ to ignition temperature for the burner âgas.
Which ovens or models is the WB13T10045 â¤compatible âwith?
WB13T10045 fits a range of GE⢠gas ovens and ranges. Compatibility depends on the oven model and mounting/wiring configuration. âAlways confirm fit⣠by⣠checking your⤠appliance model number against theâ part ânumber in the GE parts âŁlist or the retailer’s âŁcompatibility checker before purchasing.
What are the commonâ symptoms of aâ failing WB13T10045?
Typical symptoms include: the oven burner does not light, long glow time before â¤ignition, âburner takes many attempts to light, the⤠oven⢠cycles off and onor the ignitor does not⤠glow at all. A weak âŁignitor may glow but not âdraw enough current to âopen the âgas valve, causing no ignition.
How can I test the âignitor to see if it’s bad?
Basic tests:â with powerâ off,use a multimeter to check for âcontinuity (ohms). A properly âfunctioning hot-surface ignitor will show continuity (a finite resistance). A⤠completely open reading indicates failure. Cold resistance will vary by model (commonly in the tens to low hundreds of ohms); consult the service sheet for â˘the exact spec. for a definitive test, measure operating current âwith âa clamp ammeter during a call for â¤heat-if the ignitor’s operating current is below the manufacturer’s spec⣠(typically requiring several amps), it won’t allow the gas valve to open and should be replaced.
How do I safely replace the WB13T10045?
Turn â˘off electrical power and shut offâ the gas supply before starting. â¤Remove the âoven bottom or access panel⢠to reach theâ ignitor, disconnect its wiring connectorand âunfasten⢠its mounting screws. Replace with the exact âreplacement part, secure mounting screws, reconnect wiring, restore power âand gas, thenâ test for proper â˘operation and check for gas leaks. âDo not⢠touch the ceramic/glass surface â˘of the ignitor element with bare hands-oils can âdamage it. If unsure, hire a qualified service technician.
My ânew ignitor glows but the burner still won’tâ light – what should I check?
Ifâ the ignitor glows but the burner doesn’t⤠light,⤠possible⢠causes includeâ insufficient ignitor current, a⤠faultyâ gas safety valve, bad wiring or connector,⤠a defective oven control⣠boardor no gas supply/closed gas valve. Measure the â˘ignitor’s⣠operating current and inspect voltage⢠at the ignitor and continuity to the âgas valve. If theâ ignitor draws â¤proper current⣠but the valveâ doesn’t⤠open, the gas valve is likely the problem.
How long does a WB13T10045 ignitor⤠typically last⢠and how âŁmuch does it cost?
life expectancy varies âwith usageâ and operating conditions â˘but many hot-surface ignitors last several years (commonly 5-10 years). Factors such as â˘frequent â¤on/off cycles, power surgesor contaminationâ shorten⤠life. retail prices âŁvary⣠byâ supplier and region; typical aftermarket prices are commonly inâ the â¤tens of dollars range-check authorized⤠GEâ parts dealers for current pricing.
Any tips to extend the â¤life of the ignitor?
Avoid touching the heated element with bare hands, keep the oven interior clean so the ignitor isn’t â¤coated â˘in debris, avoid repeated⤠short cycles of ignition, ensure properâ household voltage, âand make sure the ignitor is⤠mounted and wired correctly. âRegular inspection and prompt replacement âŁat first âŁsigns of failureâ prevent additional strain⤠on the gas valve and control electronics.
To Conclude
The WB13T10045 GE oven âŁignitor assembly plays â˘a central role in gas oven operation by initiating and sustaining the ignition process that allows burners to light⣠and the oven to reach and maintain⢠set temperatures.⤠As a component designed⤠to âdeliver a consistent and timed heat âsource, it directly affects cooking performance, temperature accuracy and, importantly, safe âcombustion within the appliance.
As ignitor failure is a common cause âŁof oven malfunction-ranging from slow heating to a complete inability to light-the⢠value of accurate diagnosis⣠cannot be overstated. Confirming the ignitor’s condition through appropriate testing âand inspection helps distinguish it from other potential causes and âavoids âŁunnecessary ârepairs. When replacement is required, using a compatible partâ such as the âWB13T10045⣠and following âŁcorrect⢠installation and safety procedures ensures reliable, long-term operation.
