WB13T10045 â˘GE Ovenâ Ignitor Assembly isâ a replacement igniter module used in gas ranges and â¤ovens; âit is a â¤hot-surface â¤ignition componentâ designed to heat to â˘a high temperature and initiate combustion of the oven burner. As an ignitor assembly, it typically includes the ceramic/glass-encased heating element and mounting bracket/wiringâ harness required to âŁposition the⣠element at the burner and connect it to the appliance harness.⣠The âŁpart is a field-replaceable electrical â¤component rather than a gas-valve or mechanical regulator.
Inside the appliance, the ignitor’s roleâ is to heat âŁto a temperature sufficient to ignite incoming gas and âto draw the electrical characteristics⢠(current/voltage) expectedâ by the gas⤠safety valve and control system so âthe valve will â¤open. It interfaces with the oven control/ignition relay, the gas safety valve(s)and the burner assembly; it may also be monitored â˘indirectly by control âelectronics for proper ignition timing and flame establishment. Proper operation depends on correct mounting, intactâ insulation and âconnectors, âŁand the ignitor reaching â˘itsâ specified âŁglow temperature and electrical characteristics within expected time limits.
In âthe article you will⤠find a technical description of how the âWB13T10045 âignitor functions, âguidance âŁon â¤checking compatibility and identifying the âŁpart in an appliance, common failure symptoms⤠(such âas longâ ignition times, no ignition,⤠orâ visible cracks/damage), diagnostic steps a technician or experienced âŁowner can use (visual âinspection, resistanceâ checks, âand operational tests)and practical considerations for safe replacement and reassembly. â¤The coverage emphasizes measurable diagnostic criteria and installation â˘considerations rather than promotional⢠claims.

Function and âRole ofâ the Oven Ignitor assembly within GE Gasâ Oven Systems
The WB13T10045 GE âOven Ignitor⤠Assembly is a hot-surface ignitor designed to provideâ the thermal and electrical⣠conditions required to actuate the oven’s gas âŁvalve inâ GE gas ranges. When the oven control âŁcalls for heat, the control⤠applies line âvoltage to the ignitor; the element heats to aâ high temperature and âits resistance changes such that âit draws theâ steady-state current necessary to allow the gas safety valve toâ open. Properâ function â˘depends on correct mounting, intact wiringâ harness and connectorsand sufficient supply voltage-any degradation in â˘the ignitor’s emission or in the supply will alter warm-up time âand can prevent the valve from releasingâ gas even â˘when the control is operating normally.
Technicians diagnose the ignitor by observing a visible glow, measuring âcurrent draw during a call for flameand checking resistance against expected âranges⣠for the part; a weak ignitor will glow dimly, take considerably longer â˘to reach operating temperature,⤠or fail to draw âŁthe required current, âresulting in delayed â¤ignitionâ or âno ignition. Replacing the âWB13T10045 GE Oven Ignitor âŁAssembly typically restores proper ignition when the gas valve âandâ control⤠board are functional,but a confirmed⤠repair plan should include verifying supply⢠voltage at â˘the connector,confirming mechanical fit⢠and âŁorientation of the ignitor âŁin the burnerâ tube,and testing the gas valve separately if ignitionâ problems persist.
- Common⢠failure indicators: âno glow, slow glow, oven control cycles without lightingor extendedâ pre-ignition time.
- Basicâ diagnostic âchecks: visual glow, line-voltage presence during âŁcall-for-heatand measured current draw under load.
- compatibility⣠factors: â¤matching connector type,mounting bracket,and âoven⣠model series to ensure correct alignment and electrical interface.

How the WB13T10045 GE Ovenâ ignitor Assembly Works Inside the âAppliance: Electrical, Thermaland Control Interactions
The WB13T10045 GE Oven Ignitor assembly is âaâ hot-surface⢠ignitor that converts electrical energy into radiant heat to igniteâ the⢠oven’s gas. Electrically, the ignitorâ is a resistive heating element that is â¤driven by the oven control during the bake/ignite⣠sequence;⢠it must âdraw sufficient current so that the âcontrol can apply power to the gas valve. Thermally,â the element âŁmust reach a stable âglowing temperature so the â¤gas âintroduced by âŁthe valve âwill reliably ignite. in practical terms,theâ component’s electrical continuity,connector type,and thermal output determine⢠whether â¤the control module will allow the valve to open and maintain a stable burner flame,so replacement parts must match the original’s electrical âŁand mounting characteristics toâ preserve correct behavior and safety margins.
- Observable âbehavior: steady luminous glow during preheat; failure frequently enough shows as weak or no glow.
- Electrical role: high inrush/current drawâ during warm-upâ that the control interpretsâ before energizing the gas valve.
- Failure modes: open circuit,excessive resistance â˘(insufficient heat),or intermittent contacts at the âconnector.
| Item | Description |
|---|---|
| Electrical interface | Connected to control board power output; must present⢠the expected resistance/current draw for correct sequencing. |
| Thermal âresponse | Heats toâ a⢠visible glow within the control’s preheat window; insufficientâ heating prevents reliableâ ignition. |
| Compatibility | Physical mounting, âconnector typeand electricalâ characteristics must match the original to ensure proper⢠operation. |
Control interactions âŁareâ sequence-driven: the oven control supplies voltage to the ignitor,â waits for the characteristic current/temperatureâ signature, âŁthen applies⢠power to the gas â¤valve. If the ignitor’s resistance is too high or it warms slowly, the control may delay or disable the valve output, producing long âpreheat times or âŁfailure-to-light faults. For⤠troubleshooting, technicians commonly verify continuity and check voltage at the ignitor during a start cycle; typical field checks include confirming aâ steady glow under live power and comparing measured âŁvalues to âOEM service⤠data. Replacing a degraded ignitor with a⢠correctly⢠specified unit restores the⢠expected electrical load and â¤thermal output, removing⤠timing âandâ safety interlocks that otherwise prevent ânormal âignition.
Common Failure Symptoms and Quantitative â¤Diagnostic Indicators for Ignitor Degradation
The WB13T10045 GE Oven Ignitor Assembly is a glow-bar style ignitorâ that provides the âheat and electrical âdraw ânecessary to actuate the oven’s gas safety valve and allow burnerâ ignition.In service the ignitor must reach a visible orange glow within a reproducible time window and present the â˘expected electrical characteristics; a reduced glow intensity,⢠unusually long time-to-glowor an out-of-range resistance/current⢠reading are the primary indicators that the component can⤠no longer reliably open the gas valve.Technicians confirm operation by measuring âcold⤠resistance with a digital â¤multimeter, âobserving time-to-glow under normal line â˘voltageand by verifying that the operating current âŁmeets the oven’s⤠specification so the gas valve receives âŁsufficient holding current to open safely.
- Insufficient⣠or no visible glow while power is applied
- Long preheat times or ovenâ failing to âreach⣠set temperature despite control signals
- Cold-resistance âvalue outside the expected â˘range
- Operating current below theâ threshold needed to open the gas âvalve
- Physical âdamage: cracks, flaking coatingor broken terminals
| Item | Description |
|---|---|
| Cold resistance | Typical range ~30-100 âΊ (measure with power removed). Values significantly higher or open indicate filament damage. |
| Operating current | Approx. 2-4 A at 120 â˘V for common glow ignitors; sustained âcurrent below â¤expected can prevent gas valve actuation. |
| Time-to-glow | Normal warm-up commonly under 30 seconds; times consistently above ~40 seconds suggest âŁdegradation or decreased emissivity. |
Inâ practical diagnosis, startâ with a âcold-resistance check, then observe the ignitor under âlive conditions (safely)â to time â¤the⣠glow⢠and, if available, measure current with a clamp meter. Such as, âan ignitor that measures 80 Ί cold but only⣠draws 1.5 A when hot and glows dimly will frequently enough fail to open the gas valve even though the resistance reading alone looks plausible. Replacement â¤with the correct WB13T10045 GE Oven Ignitor Assembly orâ an âequivalentâ OEM-specified ignitor⣠is recommended when electrical or visual indicators fall outside the ranges above; always⣠follow the oven manufacturer’s service proceduresâ for safe⢠verification and replacement.
Compatibility, Replacement Considerations, Installation Best Practices⢠and Troubleshooting Protocols
The WB13T10045 GE Ovenâ Ignitor Assembly âis a âŁhot-surface ignitor designed âto heat to a high âŁtemperature and provide the thermal⣠energy ârequired to open the gas safety valve and ignite the burner.â In operation it functions as a resistiveâ heating element: when the oven controller appliesâ line voltage during a âbake or broil cycle, the element must reach itsâ operating temperature and visibly glow;â failure modesâ include reduced glow intensity, hairline cracking of the ceramicâ elementor broken terminals. Confirm compatibility by⣠matching physical mounting â¤points, âterminal type (spade, pigtailor ceramic leads) and the electrical rating specified for your GE model-an identical-looking ignitor can still be unsuitable if the connector orientation âor mountingâ flange differs, so check OEM cross-reference and⢠the oven model number beforeâ replacement.
Installation best practices â˘begin with disconnecting âpower and shutting off the gas supply, then verifying that the âŁreplacement â˘ignitor aligns with the existing bracket âandâ thatâ wiring insulation and âconnectors are intact. During commissioning, observe theâ ignitor for a âbright, even glow when the âcontroller calls for ignition âand verify that the gasâ valve receives the correct⤠control signal âonly âŁafter the ignitor reaches temperature; if the ignitor glows but the valve does not open,⣠isolate the valve⣠circuit andâ test the valve coil. Troubleshooting âŁprotocols⣠should include a âcold continuity/resistance check to detect open filaments, an⤠operational âcheck â˘to confirm visible glow under loadand voltage â¤checks at⢠the âŁignitor harness during aâ call for heat; document observations (glow intensity, time-to-glowand âany intermittent behavior) âto distinguish between ignitor degradation, wiring âŁfaultsor control board/gas valve failures.
- No visible glow when energized – check⤠wiring,⣠control âoutput, then replace â˘ignitor if filament open.
- Dim or slow-to-glow element -⣠likely increased resistance; â¤replace ignitor ârather than attempting repair.
- Ignitor glows but no ignition – verify gas valve actuation and continuity âŁof the âŁvalve coil.
- Physical damage, chippingor corroded terminals – replace andâ confirm correct mounting orientation and connector fit.

Q&A
What⤠is the⢠WB13T10045 ignitor assembly and âwhat doesâ it do?
The WB13T10045 is a hot surface (glow⢠bar) ignitor assembly used on âmany GE and related-brand gas ovens and â˘ranges. When the oven âcallsâ for heat the control⣠supplies voltage to â˘the ignitor; âthe ignitor heats until it glows red-hot and draws enough current to allow âthe gas safety valveâ to open and release gas to the burner,where the glowing element ignites the gas.
What are the common symptoms that this ignitor is failing?
Common symptoms include: the oven âtakes aâ long time to light,the oven ânever reaches temperature,the ignitor glows weakly or ânot at all,repeated attempts to ignite,the bake burner not lighting while broil might,or a persistent gas smell (in which case shut off⤠gasâ and ventilate). âA weakâ ignitor may glow but not draw⣠enough current âto open the gas valve.
How can I test the WB13T10045 to â¤see if it âis bad?
Start with a visual inspection â˘for cracks, â˘burn marks or a broken element.Use a multimeter toâ check continuity (a functioning ignitor will not be open). For more definitive testing, measure âcurrent draw⢠during a â˘call for heat with âŁa clamp ammeter – gas oven hot surface ignitorsâ commonly draw on the order of a few â¤amps (many fall in the ~2.5-3.6 A⢠range, but check the OEM spec for your âŁmodel). If the ignitor has⤠continuity but does not glow or draws significantly less current than âŁspecified, it is indeed weak and should be replaced. If it glows normally but the valve still⤠won’t⤠open, the gas valve âor controls might potentially be at fault.
Can â˘I replace the WB13T10045 myself, â˘and is it safe to do so?
Yes, manyâ experienced DIYers can replace this ignitor, but youâ must follow âŁsafety precautions:â turn off electrical power to the appliance âŁat â¤theâ breaker and âshut off the gasâ supply before starting. Handle the ignitor carefully â(the ceramic/glow element is fragile). If you â˘are not âcomfortable working⣠with gas appliances âŁor electrical components, hire a qualified appliance technician. After replacement, restore power â˘and gas and observe a few âignition â˘cycles to verify safe operation.
What are the basic âŁsteps to replace the⣠ignitor assembly?
Typical steps: 1) Turn off power and â˘gas. 2) âRemove⤠oven racks â¤and the access panel/oven â˘floor to reach the burner area. 3) Unplug or â¤disconnect the ignitor’s electrical connector. 4) Remove the mounting screws that hold⤠theâ ignitor/bracket to the burner box. 5) Replace â¤withâ the ânew WB13T10045 â(do not touch the ceramic/glow surface with bare hands). 6) Reattach wiring, reassemble panels and racks,â restore power and gasand test several ignition cycles.â Follow your oven’s service manual for modelâspecific instructions.
How do I know if WB13T10045 is the correct replacement part for myâ oven?
Check âyour oven’s model number (usually on a tag behind the â¤door frame, under the oven door,⤠or on the back) and look â˘it up â˘on⢠GE’s parts âwebsite or an authorized partsâ dealer. Many parts cross-reference by number; WB13T10045 is a common OEM part for multiple⤠GE/Hotpoint/other models, butâ always verify compatibility for your specific model â¤beforeâ purchasing.
How long do these ignitors typically last and is there a warranty?
Ignitor life variesâ with usage⣠and operating conditions; many last severalâ years (often 3-10â years) but âŁheavy use or power/gas cycling can shorten life. Parts sellers and manufacturers mayâ offer limited warranties-commonly â90 days to one year-depending on the âvendor. Keep your receipt and âcheck â˘the seller’s warranty policy before⤠buying.
If I replace the ignitor and the âŁoven still won’t light, what could be wrong?
If âa new â˘ignitor âglows properlyâ but the â˘burner still won’t light, â¤possible causes include⢠a faulty gas safety valve (not opening), âŁbad ovenâ control/relay, loose wiring orâ connector issuesorâ blocked burner ports. If there is âno glow from theâ new ignitor, re-check wiringâ and power. Always shut off gas instantly if you detect aâ strong gas odor⣠and call a technician.If diagnostics âare inconclusive,contact anâ appliance technicianâ to test the gas valve and control circuitry safely.
Closingâ Remarks
The WB13T10045⢠GEâ oven ignitor assembly is a critical safetyâ and performance component in gas ovens: it produces âthe heat and electrical characteristics required to reliablyâ open the â˘gas valve and ignite the burner. A functioning ignitor supports consistent oven temperatures, efficient operationand safe ignition cycles, making⢠it central â¤to â˘both everyday â¤cooking performance and⢠the long-term⣠reliability of the appliance.
