The⣠WB13T10045 GE Oven Ignitor Assembly isâ a â¤hot-surface ignitor (glow-bar) replacement component used in gas ovens and ranges; it is aâ resistive ceramic heating element mounted near the bake burner that heats â¤to a visible glow âwhen⣠energized to initiate combustion.As a discrete assemblyâ it typically includes the ceramic/glass ignitor element, mounting bracketand a connection lead or harness compatible with âŁthe OEMâ appliance wiring.
Within the appliance, the ignitor’s primary role is to provide a reliable ignition⣠source for the oven’s gas âburner and to act âas part of⢠the safety interlock between the control system âŁand the gas valve. When âthe range control applies lineâ voltage,the ignitor draws âcurrent and heats to a âtemperature⤠sufficientâ to ignite the gas; once âthe ignitor âreaches operating temperature and the âŁcircuit draws the âexpected current,theâ gas valve is released â¤to flowâ fuel to the burner. The âignitor â¤therefore âŁinterfaces âelectrically with âthe oven âcontrol or thermostat,mechanically with â¤theâ burner/mounting assembly,and functionally with⢠gas-valve/flow safety circuits-making its electrical continuity,current draw under load,and physical positioning crucialâ parameters for correct operation.
This article will describeâ how theâ WB13T10045 functions, how to âdetermine compatibility âŁwith specific GE models, commonâ failure symptoms (for âexample no ignition, extended glow timeor intermittent lighting)and practical âtroubleshooting steps suchâ as visual inspection,â resistance/continuity checksand âŁmeasured current testing⤠under power. It will âalso cover replacement⢠considerations⤠including safe isolation of mains power, âverifying â˘part fit âand electrical characteristics, proper â˘mountingâ andâ connector â¤integrityand checks to perform after âinstallation to confirm safe, reliable operation.

Functional Role and Operational Requirements â˘of the Oven Ignitor
the â WB13T10045 GE Oven Ignitor Assembly is a hot-surface ignitor that provides the thermal energy required âŁto ignite the oven’s main gas burner. âŁIn operation theâ element must⢠reach a high incandescent temperature so that⤠sufficient current flowsâ through the ignitor⤠circuit to permit the oven’s gas safety valves to⣠open and deliver âfuel.⢠The ignitor does not directly ignite the â¤gas âby a â˘spark; instead, its steady radiant heatâ allows the control system and âsafety valve logic to sequence gas flow. proper function therefore depends âon â¤matching electricalâ characteristics (connector type, resistance and â˘currentâ draw) and mechanical mounting to the oven’s original⤠specifications so the control module senses the correct⢠load before energizing theâ valve.
Operational âŁrequirements include correct line voltage, secure connector and âcorrect âphysical placement so the ignitor receives the intended⤠airflow and positioning relative to the âburner. Technicians typically verify âcontinuity and compare⤠warm/cold âresistance trends against the manufacturer’s specifications, inspect for hairline cracks or broken insulation,â and observe glow time and steady current⣠draw during âstart-up. For⤠field service, replace with⣠the exact OEM assembly âor âan approved equivalent âto maintain the designed â˘ignition timing⣠and safety behavior; improper fit or spec mismatch can âŁcause prolonged⣠glow â˘times,⤠repeated ignition attemptsor failure of the gas â¤valve to open. Practical checks and installation â˘best practicesâ reduce misdiagnosis and ensure safe,repeatableâ ignition performance.
- Common symptoms⤠of failure: extended glow â¤time, no ignition, intermittent burner lightingor visible damage to the â˘ignitor element.
- Quick service⣠checks: continuity test with a multimeter, visual inspection for âŁcracksand⣠observing start-up current andâ glow⤠behavior.
- Replacement⣠guidance: confirm OEM part â¤number and connector type, avoid bending theâ elementand â˘torque mounting⤠fasteners to prevent â¤stress âfractures.

How the âWB13T10045 âŁGEâ Oven Ignitor Assemblyâ Works Inside the âŁAppliance
The WB13T10045 GE Oven Ignitor⤠Assembly is a hot-surface (glow) ignitor that converts âelectrical energyâ into heat to âignite theâ oven’s gas. As current flows through the ceramic-coated element⢠it reaches incandescent⣠temperatures and radiatesâ heat directly to the burner port; the ignitor’s sustained âcurrent draw is what âsignals theâ oven’s gas valve â¤to open. The assembly typically includes the filament,â mounting bracket andâ plug-style harnessâ so it interfaces â˘withâ the⣠oven⤠control and gas valve; â˘mechanical fitâ and connector type determine whether a replacement unit⣠will mate âcorrectly without modifying wiring or brackets.
In normal operation the ignitor â˘begins to glow âshortly⣠after the control calls for heat and maintains sufficient⢠current⤠until the gas valve opens and combustion stabilizes. Common diagnostic checks include visual observation of glow⢠timing, a continuity/resistance check to confirm⤠the filament is intactandâ a clamp-ammeter measurement to verify the ignitor draws the required current to operateâ the gas valve. Replacing⣠the WB13T10045 withâ a⤠part that differsâ inâ geometryâ or electrical characteristics can result in delayed ignition⣠or a nonâopeningâ gas valve,â so⣠verify partâ number, â¤connector styleand âmounting⢠dimensions before installation.
- Symptoms: long⣠ignition times, oven not reaching temperatureor clicking from the gas valve.
- Diagnostics:â visual glow test, continuity/resistance checkandâ current draw measurement with âŁa âclamp meter.
- Installation checks: verify connector type, mounting bracket âŁalignment, â¤and inspect the ceramic sheath for cracks.

Commonâ Failureâ Symptoms and âdiagnosticâ Indicators of ignitor Degradation
The WB13T10045 GE Oven Ignitor⤠Assembly is a hot-surface ignitorâ that provides the heat necessary⤠to open the gas safety âvalve and start combustion in many GE⣠ovens. âIts â˘primary function is to â˘reach and sustain a surface temperature sufficient âŁto trigger the oven’sâ gas valve timing circuit; when âhealthy the element glows luminous orange-white within â10-30 secondsâ of receiving line voltage. compatibility depends â˘on mounting, connector type, âand thermal-electrical characteristics rather âthan âŁappearance alone, so technicians shoudl match the element’s electrical rating and bracket⣠geometry when replacing assemblies. Physically, the element isâ a ceramic-coated metal filament; mechanical damage, coating âŁcracksor degradedâ filament conductivity â˘will alter â¤glow behaviorâ and can prevent⢠reliable ignition evenâ if the part âfits the oven⢠correctly.
Typical failure⣠indicators areâ changes in glow intensity, extended pre-ignitionâ time, âŁor complete loss of visible glow. Practical diagnostics⢠combine⤠visual observation with basic electrical tests: â˘a âcold resistance âcheck âwith a â¤multimeter â˘and anâ operating current âor⤠voltage â¤measurement under controlled, isolated conditions. Common âŁreal-world symptoms include âintermittent flame, repeated⤠ignition â¤attempts visible as repeated glow-cool cycles,⢠or an oven control⣠that locks out ignition after multiple attempts.â Distinguishing âignitor degradation from a⢠faulty gas valve or â˘control module requires correlating theâ ignitor’s measured resistance/current and glow behavior with valve⤠actuation âtiming-if âthe⤠ignitor reaches proper temperature but the âvalve â¤does ânot open, theâ valve or control circuit is the âlikely fault.
- Dim or slow-to-glow element, extended ignition delay
- Noâ visible glow or open-circuit reading on âresistance test
- Intermittent glow with repeated ignition attempts
- Normalâ glow⤠butâ no gas âŁflow (indicates valve/control âissue)
| Item | Description |
|---|---|
| Typical cold resistance | ~50-200â Ί (measured at room temperature; varies by design) |
| typical operating current | ~2.5-4.0 A at 120 âŁVAC (measured under operating conditions) |

Compatibility and Supported GE Oven â¤Models for the WB13T10045 GE⣠oven Ignitor Assembly
The WB13T10045 GE Oven⣠Ignitor Assembly is a direct-replacement hot surface ignitor assembly that creates the required thermal emission to⣠allow theâ oven’s gas valve to âopen and the burner to light. The assembly typically combines the ceramic/glass-encased silicon carbide or silicon nitride ignitor element with⣠a metal mounting bracket and insulated⤠lead wires; when powered by the âoven’s âŁcontrolâ system it must reach a specified âhot âŁresistance⣠and⢠glow level to draw sufficient â˘current for⢠the âgas valve coils. Typicalâ failure modes include loss â˘of⤠visible glow,hairline fractures in the ignitor element,open-circuit condition on a multimeter,or gradual increase in warm-up time â˘that⤠prevents the valve â˘from opening; these behaviors explain why an otherwise-functional gasâ valve or control board can be âincorrectly suspected as the cause of âa no-heat condition.
- Common symptoms:â no ignition, âŁlong preheatâ times, continuousâ clicking from the control, â˘visible cracksâ in âthe ignitor.
- Compatibility considerations: confirm connector type, lead lengthand bracket⢠orientation against â˘the âoven model tag â˘before installation.
- Diagnostic tip: âŁverify â¤visual glow and measure continuity/resistance per technician manual rather âŁthan relying solely on functionalâ checks.
Compatibility for the WB13T10045 GE Oven Ignitor Assemblyâ spans a range of GE-built gas ranges and wall ovens; however, interchangeability depends on mechanical⤠fit andâ electrical connector style rather than the brand name alone. âserviceâ technicians should verify the appliance model tag and âthe original part number before ordering âŁor installing âa replacement because variations in âlead â˘length, mounting flange âdimensionsor terminal⢠type can prevent a correct installation even when the ignitor element â˘appears similar.â In practice,â cross-referencing the oven’s âfull â¤modelâ number with a â¤parts database or âOEM service manual and checking the ignitor’s operating voltage and âdiagnostic resistance range are⤠the reliable ways to confirm support for aâ particular GE model.
| Item | Description |
|---|---|
| Electrical supply | Operates âŁfrom the appliance’s line supply (nominal⤠120 VAC control⣠circuit); verify with service documentation. |
| Mounting / connector | Integral bracket and insulated leads-confirm physical dimensions and connector type âmatch the âoven. |
| Field diagnostics | Check for visible glow âand continuity;â consult the service manual for expected cold/hotâ resistance ranges and âmeasurement âprocedure. |
Replacement Considerations, Safety Precautionsand StepâbyâStep Installation â¤Procedures
The WB13T10045⣠GE Ovenâ Ignitor Assembly is a⢠hotâsurface â¤ignitor â˘designed⣠to âheat to incandescence and âprovide the required current draw to the gasâ safetyâ valve âcircuit so theâ valve will⢠open and deliver⢠gas to the burner.â In normal⢠operation the⤠element should glow brightâ orange âwithin a few seconds â¤and maintain a stable⢠temperature; a dim, slowâtoâglowor crackedâ element âindicates â¤reduced emission and will prevent the valve âfrom opening.â When selecting a replacement, verify â˘the mounting flange, lead length, connector typeand electrical⣠ratings against the⤠oven model⤠plate-physical fit and âmatching⣠electrical characteristics âdetermine compatibility more than cosmetic similarity. For example, a⤠directâfit âŁignitor for a singleâoven â¤GE range willâ have identical bolt spacing and a twoâpinâ ceramic â¤connector, while aftermarket options that alter lead lengthâ or mounting may requireâ minor â¤bracket modification or splicing, which increases installation complexity and failure risk if not done correctly.
Follow â˘electrical isolation and gas shutoff procedures before anyâ disassemblyand â˘use a multimeter to check elementâ continuity and approximate â˘cold resistance as part⤠of preâinstallation verification. Typical cold⤠resistance âand current draw can vary by design; âvalues outside expected ranges (see table) generally warrant replacement rather than ârepair. Handle âthe âglass/ceramic element by theâ mount only-oils from skin â¤can create hot spots and âŁshorten life-and avoid operating âthe oven with a⢠visibly⢠cracked element. After installing the replacement, reassemble the burner components, restore power and âŁgas, observe⢠the âignition⢠sequence for consistent glow âfollowed by valve openingand perform a â¤leak⣠check âon gas fittings; â˘if ignition âisâ intermittent or the ignitor â˘takes excessively long to glow, recheck âwiring, connector integrityand electrode/burnerâ alignmentâ rather than continuing â¤operation.
- Disconnect âpower at the breaker⣠and shut off the gas supply; confirm with a nonâcontact voltage tester and âgas âvalve in theâ off position.
- Access the ignitor by âremoving⤠oven racks and the access panel; âsupport the burner assembly if required to reach mounting screws.
- Disconnect the twoâpin connector and âremoveâ mounting â¤screws; avoid touching the ceramic/glass element surface.
- Install the new WB13T10045 âGE â˘Oven⣠Ignitor Assembly with âoriginal hardware, reconnectâ theâ connector, â¤and restore panels.
- Measure continuity â¤and coldâ resistance with a âmultimeter, restore power/gas, observe ignitionand â¤perform a soap test on gas⣠joints to⣠confirm no leaks.
| Item | Description |
|---|---|
| Typical operating voltage | 120 âVAC⣠(line voltage to ignitor circuit via oven control) |
| Typical cold resistance | Approximately 40-120 Ί (varies by design; useâ as⣠diagnostic guideline) |
| Typical running current | Approximately 2-4 A at rated voltage (element must drawâ sufficient current to⤠open gasâ valve) |
Troubleshootingâ Procedures andâ Electricalâ Diagnostics for Ignitor Faults
The⢠WB13T10045 GE Oven ignitor Assembly is a hot-surface ignitor designed to heat âa⢠resistive⣠element until it emits a visible orange glow and allows â¤the oven’s gas â˘valve â¤circuit to complete.â In normal operationâ the element heats âŁquickly and draws the required current so the⤠safety gas valve senses adequate âamperageâ andâ opens;â failure⤠modesâ include open circuit,high cold resistance causing a âweak or slow glow,or intermittent thermal breakdown that prevents sustained ignition. Physical compatibility (mounting flange, lead⣠lengthand connector type) must matchâ the original unitand replacement should preserve the same electrical ratings and harness⣠connection to ensure properâ timing and flame-proving behavior inâ the⢠control sequence.
Troubleshooting begins â˘with âa controlled,safety-firstâ inspection: disconnect power and visuallyâ check for cracked â˘insulation,burnt connectors,or mechanical damage before testing. Useâ an ohmmeter to confirm⢠continuity and compare resistance trends âagainst known-good units; a fully âŁopen elementâ indicates failure, while significantly âhigher âthan expected resistance correlates with reduced heat output and slow⢠or non-existent glow. For âfunctional diagnostics with power applied, measureâ voltage at the ignitor connectorâ during⢠a call forâ heat-presence of correct control voltage â˘with no glow pointsâ to a â˘defective ignitor, while absence⣠of voltage indicates aâ control or wiring fault upstream. Practical â¤example: if a technician reads the expected control voltage atâ the âignitor terminals⣠but observes only a faint âglow⤠and the gas valve ânever opens, replacing the WB13T10045 GE âŁOven Ignitor âŁassembly is typically required because the element cannot⣠reach the current drawâ needed to actuate the valve.
- Common symptoms: noâ ignition, slow/weak⣠glow, oven cycles âbut fails to lightor safetyâ lockouts after repeated failed attempts.
- Basic electrical tests: continuity check (power off),â cold⤠resistanceâ measurement, live voltage âŁcheck during demandand observing current draw if â¤available.
- Safety âsteps: disconnect power before ohmâ checks; whenâ measuring live voltage use insulated tools and follow local electrical safety procedures.

Q&A
What isâ the âŁWB13T10045 and what⤠does it do â˘in my GE oven?
The⢠WB13T10045 âŁis a hot-surface ignitor assembly used in many GE/Hotpoint gas âovens. When âŁthe oven calls for heat the control board âor thermostat â¤sends power âŁto the ignitor;â the ignitor glows red-hot and, once it âdraws enough current/heat,⣠the oven safety gas valve opens and gas flows to the burner where it is ignited by âthe hot surface.
How do Iâ know if the WB13T10045 ignitor is âbad?
Common symptoms of a failing ignitor include the burner taking a long time to light,the⢠oven â˘not âreaching⤠temperature,continuous clicking without ignition,or⣠no glow at all from the ignitorâ when the oven tries âto ignite.⣠You can also test it electrically: withâ power off and the⢠ignitor⢠disconnected, check continuity â¤with a multimeter – an âŁopenâ circuit indicates âa failed element. For a live âŁoperational test, technicians measure the current draw when the ignitor is glowing; an ignitor that fails to draw its expected operating current likely won’t open the⣠gas valve.
Can I replace the âWB13T10045 myself and what⢠safety âprecautions should I take?
Yes, a knowledgeable DIYer can replaceâ it, but â˘you must take proper safety âsteps: turn off electrical powerâ to the oven at the breaker, â¤shut off the gas supply, â¤allow the oven to fully cooland follow the manufacturer’sâ disconnection â¤steps. âavoid touching the âignitor’s ceramic/glass surface with⢠bare⢠fingers (oils can shorten its âlife). If âŁyou’reâ not comfortable working âwithâ gas appliances or electricity,hire a qualified technician.
How do I⤠test âŁthe â¤WB13T10045 with a multimeter?
Disconnect powerâ and remove the ignitor’s connector. Set your âmultimeter to the resistance (ohms) range and âŁmeasureâ across the âtwoâ terminals ofâ the ignitor. A completely open reading (infinite âŁresistance) means the filament is broken and the ignitor needs replacement.â A finite resistance indicates continuity, but that doesn’t guaranteeâ full operating performanceâ – âan ignitorâ can âhave continuity but stillâ fail to reach the required heat/current to âopen âthe gas âvalve. For a full operational check,a live-current (amp) measurement during ignition is used (see⣠a qualified technician if unsure).
Is the â˘WB13T10045 compatible with âmy oven model?
Compatibility depends on⤠the oven â˘model and production âdate. WB13T10045 is a GE OEM ignitor used onâ a number of GEâ and Hotpoint gas âŁovens, but you should verify fitment before buying – check your oven’s model number and compare it to the part’s compatibility â˘list⣠from the partsâ supplier or GE’s parts lookup.Do not rely onlyâ on visual similarity; mounting âbrackets, connector type, âand flame âposition â¤must â¤match.
What tools and parts do âI need to replace the WB13T10045?
Typical âtools: Phillips/flat âscrewdrivers, nut drivers or socketâ set â(ofen 1/4″-5/16″), needle-noseâ pliers for wire connectorsand work gloves. You’ll need the replacement WB13T10045 ignitor assembly âand, optionally, new mounting screws if the â˘originals areâ corroded. If theâ ignitor uses a quick-connect â˘harness, make sure the connector type matches or replace the connector as needed.
After âinstalling âa new WB13T10045 the oven still won’tâ light. What â˘should â˘I âcheck ânext?
If the new ignitor glows but the burner doesn’tâ light,check the following: confirm the âŁignitor is drawing its expected operating current (a weak draw may not open⤠the safety valve),verify â˘the gas supply and âthat the⣠oven âsafety â˘valve is âfunctioning,inspect âwiringâ and connectors âfor damage or incorrect connections,and check⣠for control âŁboard faults. If the ignitor does not⢠glow âŁat all⢠after installation,⢠re-check power⤠and wiring.When â¤in doubt,call a qualified appliance technician to â¤diagnose âŁgas valve⤠or control âissues.
how long does the âWB13T10045⢠usually â¤last and where can I buy a replacement?
Life varies with usage and conditions;⢠many ignitors last severalâ years but can fail⣠sooner if exposed to rough handling or contamination.To âbuyâ a replacement, use authorized parts dealers,⣠the manufacturer’s parts storeor reputable online appliance⣠parts â¤retailers. Prefer OEM parts (WB13T10045) for correct âfit and performance, âŁand check the seller’s return policy and warrantyâ in case of defects.
