WB13T10045 GE Oven Ignitor Assembly is a hot-surface ignitor (glowbar) assembly used in GE gas ovens and ranges. It consists of a ceramic or silicon-based heating element mounted with a bracket and electrical leads, designed to reach ignition temperatures when supplied with line voltage. As a discrete replaceable component it is identified by its mounting footprint and connector type, and is commonly listed as an OEM replacement part for compatible GE models.
Within the appliance the ignitor’s role is to produce the heat necessary to ignite the gas delivered to the bake or broil burner and to provide the correct electrical characteristics for the oven’s safety circuit to allow the gas valve to open. It interfaces directly with the oven control and safety system (gas valve/safety interlock), the wiring harness and connectors, and indirectly with temperature sensing and control subsystems that regulate burner operation. Proper electrical resistance and cold amp draw are essential characteristics that determine weather the control will energize the gas valve.
In this article you will find a technical overview of the WB13T10045 ignitor’s function and typical construction,guidance on compatibility and identification for model matching,common failure symptoms (for example no ignition,extended preheat time,or intermittent flame),practical troubleshooting methods such as visual inspection,resistance/continuity and amp-draw diagnostics,and considerations for safe and correct replacement including electrical ratings,mounting orientation,and connector compatibility.

Function and Role of the Oven Ignitor in GE Gas-Oven Control and safety Systems
The WB13T10045 GE Oven Ignitor Assembly is a hot-surface (glow-bar) ignitor designed to provide the thermal energy required to light the oven burner and to satisfy the electrical safety interlock that controls gas flow.When the oven calls for heat the control board applies line voltage to the ignitor; the element heats to a bright red and delivers the surface temperature needed to ignite the gas when the safety valve opens. The oven’s gas valve or control circuit monitors the ignitor’s electrical behavior (primarily its current draw as it heats). If the ignitor fails to reach the specified heating/current threshold within the controller’s timing window, the safety logic prevents the gas valve from opening, eliminating the risk of unignited gas entering the oven cavity.
- typical failure symptoms: oven won’t light, long ignition delays, dim or no glow, or the bake burner igniting intermittently.
- Electrical behavior used for diagnosis: open circuit or high cold resistance, or reduced current draw when energized indicates deterioration.
- Compatibility checks: confirm mounting bracket, terminal type, and harness fit before substituting parts.
Technicians use the ignitor’s electrical and thermal behavior to distinguish between control, valve, and ignitor faults-measuring cold resistance and observing glow and current under mains voltage are standard checks. In practice, replacing a failing ignitor with the correct assembly restores normal warm-up time and safety function; during replacement ensure power and gas are isolated, verify connector polarity and insulation, and confirm the ignitor seats properly in the burner pocket to maintain correct flame transfer. For inventory and service planning, keep the matching assembly and a compatible gasket or bracket on hand when servicing multiple GE models to minimize downtime.

How the WB13T10045 GE Oven Ignitor Assembly Works Inside the Appliance
The WB13T10045 GE Oven Ignitor Assembly is a hot‑surface ignitor used in GE gas ovens to initiate burner combustion. Electrically heated by the oven control, the ceramic/silicon element converts line voltage into heat and visibly glows, and its electrical current draw functions as part of the safety circuit that permits the gas valve to open. The assembly mounts adjacent to the burner and typically includes the ignitor element, mounting bracket, and connector so it can be fitted into ovens that specify this part number as a direct replacement; correct electrical connection, mounting orientation, and connector type are required for reliable operation and compatibility with the oven’s control and valve system.
- Common operational symptoms: no glow or slow/no ignition,long pre‑heat times,or repeated ignition attempts.
- Basic diagnostics: visual glow check, continuity/resistance measurement with a multimeter, and current draw measurement to confirm it reaches the required operating current to actuate the gas valve.
- Service note: always isolate electrical power (and gas supply where applicable) before testing or replacing the ignitor assembly.
failure modes are typically element breakage or increased internal resistance, which prevents the required current flow even if the element glows faintly; conversely, an ignitor that glows normally but does not allow ignition can indicate a downstream gas valve or control fault rather than the ignitor itself. For technicians, practical replacement decisions hinge on match of the part number, connector style, mounting screw locations, and observable test results – for example, an ignitor with an open circuit or no visible glow should be replaced, while a unit that glows but fails the current draw test points to further valve or control diagnostics.

Common Failure Symptoms and Diagnostic Measurements for ignitor Degradation
The WB13T10045 GE Oven Ignitor Assembly is a hot-surface ignitor intended to heat to a high temperature and provide sufficient current to the gas safety valve so the valve will open and allow burner ignition. As the ignitor ages it develops higher filament resistance and slower thermal response; that behavior reduces the current available during the valve actuation window and produces delayed ignition or failure to light. Confirm the part number and model compatibility before replacing an ignitor, because variations in electrical characteristics and mounting can affect performance and safety when used in a different oven platform.
Diagnosing ignitor degradation relies on objective measurements and observable symptoms rather than runtime assumptions. Common diagnostic checks include a cold ohms reading across the ignitor, a powered current draw test while the ignitor is energized, and timing the interval from energization to full bright glow; an open circuit or a cold resistance considerably higher than the OEM specification indicates internal damage or drift. Practical examples: an oven that takes far longer than the specified preheat time and shows a visibly dim glow often has an ignitor that no longer reaches required operating current, and an ignitor that never glows should measure as open on a multimeter.Technicians should isolate power, perform a cold-resistance check, then, where safe and allowed, perform a live-current measurement or compare behavior to a known-good ignitor to confirm replacement is necessary.
- slow or dim glow – long time-to-full-glow or reduced brightness; suggests increased filament resistance.
- Oven fails to light or long preheat – insufficient current to open gas valve during ignition cycle.
- Open circuit on continuity/ohms - immediate replacement required.
- intermittent ignition or clicking – marginal ignitor performance or loose wiring/connection.
- Diagnostic checks – cold resistance, timed glow test, and energized current draw compared to OEM reference.
| Item | Description |
|---|---|
| Cold resistance | Measured with a multimeter; degraded ignitors typically show higher-than-specified ohms (often in the tens to low hundreds of ohms depending on model); compare to OEM spec or a new unit. |
| Time-to-full-glow | Measure interval from energization to bright orange glow; significantly longer than factory expectations (commonly under 30-45 seconds for many designs) indicates loss of heating efficiency. |
| Open circuit | A resistance reading of infinite/OL indicates internal break and immediate replacement. |
| Energized current draw | Should meet the gas valve actuation requirement; a reduced amperage under load prevents valve opening even if the element glows faintly. |
Compatibility, Replacement Considerations and Installation Procedures for Affected GE Oven Models
The WB13T10045 GE Oven Ignitor Assembly is a replaceable glow-bar ignitor used on many GE gas ovens to produce the heat required to open the oven gas valve and initiate combustion. The component acts as a resistive heating element: when supplied with mains voltage it must reach a specified surface temperature and draw sufficient current so the gas valve senses an operating load and opens. Typical field symptoms of a failing ignitor are a visibly weak or slow glow, extended ignition delay, or complete absence of ignition; these behaviors frequently enough coexist with normal continuity readings on a multimeter, so technicians should evaluate both visual performance under powered conditions and circuit measurements against the oven’s service specifications before declaring a replacement necessary.
When replacing a WB13T10045 GE Oven Ignitor Assembly, confirm the part number, terminal type, and mounting orientation to ensure mechanical and electrical compatibility; physical fit and connector style (spade push-on, insulated terminals, or harness) matter as much as the part number. Follow safe installation practice: isolate electrical power at the breaker and shut off the gas supply, remove oven racks and the access panel, note the ignitor’s orientation and bracket position, disconnect wiring, transfer or replace the mounting hardware, and secure the new ignitor without over-tightening. After reassembly, restore gas and power, observe several ignition cycles to verify a steady glow and prompt valve opening, and perform a leak check on gas fittings if anything was disturbed.
- Safety first: shut off breaker and gas supply before work begins.
- Verify part number and terminal/mounting compatibility against the oven model.
- Handle the ignitor by its ceramic base; avoid touching the element surface.
- Test by observing glow temperature and measuring circuit continuity and voltage under load.
- After install, monitor multiple ignition cycles and check for gas leaks.

Q&A
What is the WB13T10045 and which ovens is it compatible with?
The WB13T10045 is a GE OEM hot surface ignitor (glow bar ignitor) used in many GE, Hotpoint and some Kenmore gas ranges and wall ovens.It heats to a high temperature to open the oven’s gas safety valve and ignite the burner. Compatibility is determined by your appliance model number – always verify the part number or use the appliance model lookup on the manufacturer or parts supplier site before purchasing.
What are the common symptoms that the WB13T10045 is failing?
Typical signs include the oven not heating, very long ignition times (ignitor glows but gas never opens), the ignitor glowing dimly rather of bright orange, repeated clicking, or the oven taking unusually long to reach temperature. Visual damage such as cracks in the ceramic or broken/glazed element is also a clear sign of failure.
how can I test the ignitor to confirm it’s bad?
Start with a visual inspection for cracks or broken glass. With the appliance power off, check for electrical continuity using a multimeter – an open circuit means the ignitor is bad. For a live test (only if you are qualified and follow safety precautions), when the oven calls for heat you can verify the ignitor is receiving voltage; if it is receiving the correct voltage but not drawing current or not getting hot bright enough, it is likely defective. As specifications vary,use the appliance service manual or part datasheet for exact test values and take proper precautions when working with live circuits.
Can I replace the WB13T10045 myself and what safety steps should I follow?
Replacement is within reach for competent DIYers who are comfortable working on gas appliances. Always disconnect electrical power at the breaker and turn off the gas supply before starting. Avoid touching the ignitor surface with bare hands (oil from skin can damage it) and handle it by the base. If you are not experienced with gas line components or live electrical testing, hire a qualified appliance technician – improper installation can create a fire or explosion hazard.
What resistance or current readings should I expect from this ignitor?
Cold resistance specifications vary by design, but hot surface ignitors typically show a low resistance (tens to low hundreds of ohms) and will show continuity on an ohmmeter. When operating, the ignitor draws several amps at line voltage. As exact resistance and current specs differ between models, consult the oven service documentation or the part datasheet for the correct values.A very high resistance or open circuit indicates failure.
How long does a WB13T10045 usually last and what causes premature failure?
Lifespan varies with usage but many ignitors last several years – frequently enough 3-8 years depending on cycle frequency and oven conditions. Common causes of premature failure include thermal cycling (repeated heating/cooling), moisture, vibration, physical damage, contamination (grease or food buildup), and electrical surges. Correct installation and avoiding contamination help extend life.
Are there aftermarket alternatives and how do I make sure I buy the correct replacement?
Aftermarket replacements are available and can be less expensive, but verify fit, connector type, mounting style, and electrical ratings match the OEM part. Use the appliance model number or the OEM part number (WB13T10045) to cross-reference alternatives. Purchase from reputable suppliers, check return/warranty policies, and compare photos and specifications to ensure a proper match before installation.
Concluding Remarks
The WB13T10045 GE oven ignitor assembly is a critical component responsible for initiating and sustaining the gas ignition process in compatible GE ovens.Its reliable operation directly affects oven heating performance, temperature consistency, and overall appliance efficiency; when the ignitor functions correctly, burners light promptly and the oven maintains intended cooking temperatures, contributing to predictable and safe oven operation.
Because symptoms of a failing ignitor can mimic other issues, accurate diagnosis and timely replacement with the appropriate part are important to restore proper function and avoid unnecessary component wear or service costs. engaging qualified service personnel or following manufacturer guidance for identification and replacement helps ensure compatibility, safety, and long-term reliability of the appliance.
