WB13T10045 GE Oven Ignitor assembly is aâ hot-surface ignitor⤠(glowbar) designed for use in GE gas ovens â˘and ranges. âAs a purpose-built electrical heating element typically mounted adjacent to theâ bake â¤or broil burner, the assembly contains the ceramic or â˘silicon-carbide heating element and associated lead wiring/mounting hardware required to â¤position âthe ignitor in the combustion path.
Inside the appliance, the ignitor’s role⤠is to provide a reliable ignition⣠source for the main gas burner⤠and to participate⤠in the safety interlockâ that permits the gas valve to open. Whenâ the oven control⤠calls for heat, the ignitor is⣠energized and heats to a red glow; once the ignitor attains sufficient temperature and electrical characteristics, the gas valve isâ allowed to â¤energize and fuel is admitted to the burner where the heated ignitor initiates âŁcombustion.⤠The component therefore interfaces directly âwith the oven control board, gas valve, burner assembly and related safety sensorsand its electrical and thermal âŁbehavior affects ignition⣠timing, flame stability and safety diagnostics.
In this article readers will find a technical overview of the WB13T10045’s function and construction, guidance⢠on model compatibility and installation contexts, common failure symptoms⢠(such as long ignition delays, no⣠glow, repeated spark attempts or control lockouts),â step-by-step troubleshooting checks to isolate ignitor faults from gas-supply⣠or âcontrol issuesand practical replacement considerations including electricalâ testing, correctâ mounting⤠and⢠safety precautions. The intent is to provide technicians,engineers and informed âappliance owners with the technical details needed to diagnose andâ replace the ignitor reliably and safely.

Function and Role of the Oven Ignitor assembly in Gas Oven Combustion Systems
The WB13T10045⢠GE Oven Ignitorâ Assembly is a hot-surface ignitor designed to provide the âheat â¤and current necessary to initiate and sustain combustion in a gas oven. When the oven control calls âŁfor⣠heat, theâ control â˘board supplies voltage to the ignitor so the ceramic-coated element heats âŁand glows; only⣠after the â¤element reaches its operational temperature and draws the required current will theâ oven safety gas valve be permitted to open and release gas. In practice this part acts both as the ignition source and as a current-sensing interlock: a weak or degraded â¤element âmay glow yet not draw sufficient current to actuate the valve, producing delayed ignition or no flame despite apparent heating. Confirm compatibility by⣠matching the WB13T10045 GE Oven â¤Ignitor Assembly’s mounting, connector typeand OEM part number to â¤the range model before⢠replacement.
- Dim or slow-to-glow element causing long ignition⢠cycles
- No glow or open circuit on an ohmmeter indicating a failed element
- Repeated trial-for-ignition cycles where the control attempts ignition multiple times
- Cracked ceramic,⤠damaged sheathor degraded wiring affecting performance
Technically, diagnosis requires both visual inspection and electrical verification: check for continuity and compare operating current against the â¤oven manufacturer’s specification while the ignitor is⢠poweredand inspect the mounting bracket and harness for corrosionâ or heat damage⢠that can introduce resistance. Replacement should match⣠the original assembly’s physical and electrical⢠characteristics;â improper length, terminal type, â¤or currentâ rating can prevent the safety gas valve⤠from operating correctly.⢠In field work, technicians commonly verify a suspected ignitor failure by observing glow intensity and time-to-glow under load, performing a cold-resistance checkand confirming that the gas valve only â¤opens after the ignitor reaches normal operating behavior.

How the WB13T10045 âGE Ovenâ Ignitor Assembly âworks Inside the Appliance
The WB13T10045 GE Oven Ignitor âAssembly is a hot-surface or “glow-bar” ignitor that converts electrical energy into concentrated âheat in order âto initiate âburner⤠ignition. In normal operation the â˘element receives line âvoltage, heats to its operating temperature⣠and presents the required current⢠draw to the oven’s gas⤠safety valve âŁso⣠the valve will open⤠andâ the gas will ignite. The assembly typically includes a ceramic or refractory mounting substrate, the resistive heating elementand a factory-matched electrical connector and bracketâ so that electricalâ and mechanical interfaces align with the⤠oven’s⤠burner box.
- No visible glow or â¤an open circuit âmeasured with the power off-complete ignitor failure.
- Faint glow or long ignition delay-element is weak and may not reach the current required to open the gas valve.
- Intermittent ignition or repeated cycling-could indicate marginal element performance or related control/gas-valve problems.
- Diagnostics: visually inspect the glow duringâ a heat cycle, check continuity with the power disconnectedand confirm â˘operational current draw with an appropriate metre during startup.
Compatibility for the WB13T10045 GE Oven Ignitor Assembly depends on matching the original part’s electrical âŁconnector, mounting orientation and thermal characteristics; substituting⢠an ignitor with different âelectrical resistance or mounting can prevent the âgas valve from operating correctly even if it âŁphysically fits. For practical repairâ scenarios, technicians often confirm a failed ignitor by observing that it âeither does not â¤glow or glows âbut never achieves steady bright orange; replacing it with the same OEM-designâ part restores the⢠correct heat-upâ profile and current âŁdraw in âmost cases. If the âignitor tests good yet ignition problems persist,the next⤠checks are âthe oven control and the gas safety valve,asâ those components interact directly â¤with âthe ignitor’s required behavior.
Commonâ Failure⢠Symptoms and Diagnostic⤠Indicators⤠of a Faulty oven ignitor
The WB13T10045 â¤GE Oven Ignitor Assembly is a hot-surface ignitor designed to heat to âŁa high⢠temperature⢠and provide the electrical/thermal stimulus required for the gas safety valve to open. The assembly âŁconverts âmains electrical energy intoâ radiant heat at the ignitor element; as the element reaches operating temperature it both glows visibly and establishes the current draw/profile that control circuits and gas valves expect before allowing gas flow. Physicallyâ the part includes the ignitor element, mounting bracket and the electrical lead/harness that mates to the oven control – correct connector type and mounting orientation determine compatibility with specific GE ranges and ovens, so technicians should confirm fitment⣠and wiring before installation.
Common failure⤠modes present as measurable and observable indicators rather than random faults. Typical symptoms âŁinclude no ignition, âexcessively â˘long preheat/ignition time, a dim or slow-to-glow âelementor âintermittent âŁburner operation. Practical â˘diagnostics focus on three checks: â˘visual/physical inspection (cracks, chipping, soot accumulation, broken lead), electrical continuity/resistance with power removedand live-voltage/current verification⣠when the thermostat calls for heat. A frequent practical scenario is an ignitor that still glows but does so âweakly and cannot draw sufficient current to actuate⢠the gas valve – in that case the ignitor should⤠be replaced even if it âŁshows continuity. Always isolate power and gas before removing the assembly; while troubleshooting live checks (voltage/current) can confirm whether the control is supplying line⣠voltage to the ignitor, continuity and âŁvisible glow characteristics are the â˘principal diagnostic indicators technicians rely on.
- No visible glow when oven calls for âheat
- Dim or slow-to-bright glow followed by âdelayed ignition
- Intermittent lighting or cycle failures
- Visible⣠damage: cracks, flakesor burned leads
- Gas odor without ignition (stop,⢠isolate gas/powerand investigate)
| Item | Description |
|---|---|
| Visual â¤condition | Inspect for intact ceramic/glass surface, no fragmentationand secure lead connections. |
| continuity/Resistance | With power removed,check for measurable continuity; an openâ circuit indicates a failed element. |
| Live voltage/current | When the oven calls for heat, confirm⣠the control supplies âline voltage and observe whether âtheâ ignitor drawsâ current sufficient to allow the gas valve to open. |
Compatibility,â Replacement Considerationsand Troubleshooting Procedures for WB13T10045 Installations
The WB13T10045 GE Oven Ignitor⢠Assembly is a hot-surface ignitor used âto draw the gas valve open by reaching a high temperature and allowing sufficient current flow through the safety circuit. It functions âas a â¤resistive heating element that must reach â¤a specified temperature andâ conduct enough currentâ to energize the gas valve; if the ignitor fails⣠to reach⢠that⤠threshold the â˘control system âwill ânot⢠open âthe valve. Compatibility âdepends on both electrical and mechanical factors – terminal type and spacing, mountingâ bracket orientationand the ignitor’s cold resistance and operating behavior must⣠match â¤the oven’s control and valve characteristics. Some âŁGE models âaccept direct replacements, âwhile others require an ignitor with âidentical connector geometry and similar⣠resistance/heat-up time; visually similar units can be electrically incompatible if the resistance or required warm-up current differs considerably.
- No glow or intermittent glow at startup – indicates⤠a cracked element or open circuit.
- Dim glow (glows âbut â¤oven will ânot light) – often insufficient current/heat-up âtime; measure cold resistance and live voltage during a start cycle.
- Continuity presentâ but no⣠voltage at the ignitor – control or wiring fault upstream of the ignitor.
- Correct physical fit but different terminal â¤spacing or bracket orientation – may require adapter or âŁdifferent part number.
- Corroded connectors or damagedâ harness – âcommon, simple fixes before replacement.
| Item | Description |
|---|---|
| function | Resistive hot-surface element that heats to ignite gas and allow valve actuation |
| typical cold resistance | Generally inâ the range â˘of tens to a few hundredâ ohms (model-dependent) |
| Operating voltage | Powered through the oven control on household line⣠voltage (approximately 120â VACâ when energized) |
| Mounting/connector | Match OEM bracket â˘orientation andâ terminal type (spade, plug) for reliable installation |
For troubleshooting, first â˘verify safety: disconnect power before measuring continuity or removing the ignitor.â Measure cold resistance with an ohmmeter and then, with a second person to operate the oven, â¤measure applied voltage across the ignitor during the bake/ignite cycle to confirm the control is⤠supplying line voltage. If the ignitor shows open⢠circuit when coldor⤠it glows faintly yet never âattains the temperature⢠required to open the gas valve,â replacement with⣠a part whose electrical and mechanical âspecs match the original is recommended. When replacing,confirm terminal type,bracket alignment,andâ resistance/heat-upâ characteristics; also inspect the âŁharness,connectors,and gas valve function – a working âignitor âŁcan be masked by a faulty valve or âcontrol that does not send voltage.
