WB13T10045 GE Oven Ignitor Assembly is a hot-surface ignitor (glow bar) replacement component used in many GE gas ovens and ranges; it consists of a ceramic-mounted resistive element, mounting hardware, and a wiring pigtail that together provide the heat source required to ignite the oven’s gas burner. As a thermal-electrical ignition device rather than a spark igniter, the assembly is designed to reach a high surface temperature when energized and to integrate mechanically and electrically with the oven’s burner assembly and mounting flange.
Inside the appliance the ignitor’s primary role is to heat to a specified temperature and draw sufficient current so the gas safety valve will open and allow gas flow to the burner; the oven control supplies voltage to the ignitor and monitors the ignition sequence, while the gas valve and safety interlocks depend on correct ignitor behavior to prevent unwanted gas release. The component thus interfaces directly with the oven control board, the mains supply, the gas valve circuit, and the burner manifold, and its condition affects bake and broil functions, ignition timing, and overall safe operation of the gas system.
In this article readers will find a technical overview of the WB13T10045’s function and construction,guidance on model compatibility and connector/mounting variations,common failure symptoms (such as weak or non-glowing element,extended glow time,no ignition,or control error indications),systematic troubleshooting methods (visual inspection,resistance/continuity checks,current draw and supply-voltage verification,and verification of gas-valve operation),and practical replacement considerations including selecting the correct part number,installation alignment and wiring,and post-replacement testing procedures.Safety precautions and recommended verification steps to confirm a successful repair are also covered to help technicians, engineers, and appliance owners make informed diagnostic and service decisions.

Function and Role of the Oven Ignitor in Gas Range Operation
The WB13T10045 GE Oven Ignitor Assembly is a resistive glow-bar ignitor used in many GE gas ranges to initiate burner ignition by heating to a high temperature until it conducts enough current to operate the gas safety valve. In operation the control board applies line voltage to the ignitor,the element heats and its resistance changes,and when the ignitor reaches the required temperature it draws the valve holding current so the valve will open and gas can flow. This part does not produce a spark; instead it relies on thermal emission and sufficient current draw to complete the valve circuit-so a visibly glowing element that still fails to light the burner usually indicates the ignitor can no longer reach the necessary conduction level to actuate the gas valve, a common failure mode technicians observe in aging assemblies.
- Typical behaviors: steady orange/red glow during preheat, then gas valve actuation once current threshold is reached.
- Common failure symptoms: prolonged preheat time, oven/stove not lighting even though the ignitor glows, or no glow at all indicating open-circuit or broken element.
- Diagnostic checks: visual inspection for cracked ceramic,continuity/resistance check with a multimeter,and in-situ current measurement during the ignition cycle to confirm the ignitor draws the valve holding current.
- Compatibility considerations: replacement must match mounting, connector type, and thermal/electrical characteristics to function correctly with the appliance control and gas valve assembly.

| diagnostic tip | Glows but oven won’t light - measure current during warm-up; low current indicates degraded element even if visual glow is present. |
For practical replacement and troubleshooting,technicians should verify that the WB13T10045 GE Oven Ignitor Assembly matches the original part’s mounting brackets and connector style,and should inspect the wiring harness and gas valve operation before assuming the ignitor is the only fault. During service, a functional test that observes the ignitor’s warm-up profile and measures the actual current draw at the moment the gas valve should open provides definitive evidence of a weak element; additionally, mechanical damage such as ceramic cracking or contamination can alter heat transfer and reduce performance, so physical condition is as crucial as electrical measurements when assessing compatibility and expected lifetime.
How the WB13T10045 GE Oven Ignitor Assembly Operates within the Oven gas Ignition System
The WB13T10045 GE Oven Ignitor Assembly is a hot-surface ignitor designed to heat rapidly and draw sufficient current to allow the oven’s gas valve circuit to open. Mounted adjacent to the burner orifice, the ignitor converts electrical energy into heat until its surface reaches the temperature required to initiate gas flow; many oven control systems monitor the current draw or a voltage drop across the ignitor as a safety criterion before energizing the gas valve. Technicians should verify the harness connector, mounting bracket orientation, and physical length when determining compatibility, and expect a low cold resistance in the tens of ohms range typical of hot-surface ignition elements - matching electrical and mechanical characteristics is necessary for reliable replacement performance.
In operation, the ignitor glows steadily for a warm-up interval while the control board sequences the valve; if the element ages or develops cracks the glow becomes dimmer and the circuit may fail the current threshold, producing delayed ignition or a no-ignite condition. Practical checks include a visual inspection for a steady radiant orange glow, continuity/resistance measurement with a multimeter, and observing whether the oven control advances to valve actuation; replacing the ignitor is the usual corrective action when the element no longer reaches the required temperature. Common field symptoms and speedy diagnostic cues include:
- Oven fails to light but control cycles (no or faint glow).
- Long ignition delays while the ignitor attempts to heat.
- Ignitor glows but burner does not sustain flame (weak draw or flow issue).
- Visible cracks in the ignitor ceramic or open circuit on resistance check.

Common Failure Symptoms and Electrical/Performance Indicators
the WB13T10045 GE Oven Ignitor Assembly is a glowbar-style ignitor designed to heat to incandescent temperatures and provide the required current draw to the gas valve during the oven bake cycle. In operation the element must reach a bright orange glow within a predictable time window and sustain sufficient current so the safety gas valve senses the load and opens; a weakened or cracked ignitor will either not glow, take much longer to reach temperature, or present a higher resistance that prevents the valve from operating. When replacing this part, ensure the replacement matches the original mounting, terminal harness, and electrical rating so the timing and current characteristics remain within the oven manufacturer’s design limits.
Common electrical and performance indicators of impending failure are measurable with basic diagnostic tools: a cold continuity/resistance check with a multimeter, observation of glow brightness and time-to-glow under live conditions, and verification of line voltage at the ignitor circuit when the control calls for heat. Practical symptoms technicians encounter include open-circuit readings, high cold resistance (suggesting internal element degradation), dim or sluggish warming that delays or prevents valve opening, and intermittent operation that may cause repeated safety lockouts. For quick reference, typical diagnostic checkpoints are listed below and a short technical reference table follows to aid field troubleshooting.
- No glow or open circuit on continuity test.
- Very slow or dim glow, oven never reaches temperature or cycles gas valve but fails to ignite.
- Repeated clicking or valve chatter with no sustained flame (ignitor draws insufficient current).
- Intermittent operation or visible cracks/fragmentation of the ceramic/glass coating.
| Item | Description |
|---|---|
| cold resistance (approx.) | Ignitor resistance varies by design; a significantly higher-than-expected ohm reading or open circuit indicates failure-compare to OEM spec for WB13T10045. |
| Operational behavior | Should reach bright orange glow typically within 10-30 seconds under load; slow or dim glow suggests reduced emission and insufficient current draw. |
| Voltage/current checks | Verify line voltage is present when calling for heat and that the ignitor draws the necessary current to allow the gas valve to open; lack of current despite voltage points to a weak element. |
Replacement Considerations, Installation Steps, and Safety Precautions
The WB13T10045 GE Oven Ignitor Assembly is a hot-surface ignitor that heats to a high temperature in order to allow the gas safety valve to open and the burner to light. It functions as both the heat source for ignition and as a current-draw element in the oven’s safety circuit; when the element reaches its operating temperature it must draw sufficient current to permit the valve coil to energize. Compatibility depends on matching the ignitor’s terminal type, mounting bracket, and electrical rating to the appliance model – physical fit and the correct connector are as critically important as the element’s thermal and electrical behavior. technicians should verify that the replacement part matches the oven model and control scheme (hot-surface vs. spark ignition) before installing a WB13T10045 GE Oven Ignitor Assembly to avoid misapplication that can cause prolonged glow time or failure of the valve to open.
Proper installation and safety precautions reduce risk and improve first-time repair success.Before beginning work, disconnect power and shut off the gas supply, then access the ignitor mounting area and visually inspect for cracked ceramic, broken leads, or oil contamination; the element is brittle and will fracture if handled roughly or touched with bare hands. Remove the old ignitor by disconnecting the harness and unfastening mounting screws, transfer any required gaskets or heat shields, and fit the new assembly so there is no mechanical stress on the leads. After reassembly, perform a continuity/resistance check on the ignitor and a gas-leak test at any disturbed fittings, then restore power and observe the sequence: the ignitor should glow within seconds and the valve should open once adequate current is achieved. If the ignitor glows but the burner does not light, further diagnosis of the valve, wiring, or control circuit is required rather than repeating the replacement.
- Disconnect power and shut off gas before any disassembly.
- Measure resistance/continuity of the ignitor prior to removal and after installation.
- Handle the element by its mounting plate or connectors; avoid touching the ceramic surface.
- Use proper gasket/seal placement and secure mounting to prevent heat or vibration damage.
- After installation, perform a gas-leak check and observe ignition sequence during initial test.

Q&A
What is the WB13T10045 and what does it do in my GE gas oven?
The WB13T10045 is a hot-surface oven ignitor assembly used on many GE/Hotpoint/related gas ranges and wall ovens. when the oven calls for heat the control applies voltage to the ignitor; the ignitor heats until it glows and draws enough current to allow the gas safety valve to open, producing a steady burner flame for baking or broiling.
What are the common symptoms of a failing WB13T10045?
Common signs include the oven not lighting at all, very long preheat times, oven not reaching set temperature, weak or intermittent glow (dim orange instead of bright), or repeated attempts to ignite. Note: a clicking sound on start is more typical of spark-ignition systems – a hot-surface ignitor normally glows quietly.
How can I test the ignitor to know if it needs replacement?
Start with a visual check: when the oven calls for heat the ignitor should glow bright orange within a few seconds. For a basic electrical check you can verify continuity with a multimeter - an open circuit indicates a bad ignitor. However, continuity alone doesn’t prove the ignitor’s heating capability. The most reliable test is to measure the current draw with a clamp ammeter while the ignitor is energized; a weak ignitor will draw noticeably less current and may not be enough to open the gas valve. If you’re not agreeable working live on a gas appliance, have a qualified technician test it.
Can I replace the WB13T10045 myself and what safety steps should I take?
Yes, a competent DIYer can replace it, but follow safety precautions: disconnect electrical power to the appliance and shut off the gas supply before starting. Handle the ignitor carefully (the ceramic/glass surface is fragile) and avoid touching the ceramic/glass with bare hands.Remove the oven racks, access the burner area, unmount the old ignitor, swap connectors/mounting hardware, and reinstall. After replacement restore power and gas and perform an ignition test while watching for proper flame and any gas leaks. If you detect a leak or are unsure at any point, stop and call a professional.
How do I know the WB13T10045 is the correct replacement part for my oven?
Check your range/wall-oven model number (usually on the oven frame or inside the door) and compare it to the part compatibility list from the parts supplier or GE. Verify the electrical connector type, mounting bracket orientation, and the ignitor’s physical dimensions. WB13T10045 is an OEM GE/Hotpoint part used on many models, but always confirm fit before purchasing.
how long does a WB13T10045 typically last?
Life varies with usage, but oven ignitors commonly last several years (often 3-10 years) under normal household use. Frequent cycling, power fluctuations, or mechanical damage shorten lifespan. If the ignitor becomes contaminated, cracked, or weakens electrically it should be replaced.
Will cleaning the ignitor fix ignition problems?
Light surface contamination (loose debris) can sometimes be gently removed, but avoid abrasive cleaning or touching the ignitor surface. Often a dim or slow-to-heat ignitor is electrically weak and needs replacement; cleaning rarely restores full performance if the element has degraded. Always shut off power/gas before attempting any cleaning.
How much does replacing the WB13T10045 typically cost and should I call a technician?
Part prices vary by source but the ignitor assembly itself is commonly in the low-to-mid range for replacement parts.If you are comfortable with basic appliance repair and follow safety steps, it is indeed a straightforward DIY replacement. Call a qualified appliance technician if you are unsure about electrical/gas safety,if the oven has other problems (control board,gas valve),or if you prefer not to work on live gas appliances. A technician can also test current draw and ensure the gas valve is functioning correctly after replacement.
Closing Remarks
The WB13T10045 GE oven ignitor assembly plays a central role in gas oven operation by initiating burner ignition and enabling the gas valve to open. As the component responsible for producing the heat source that allows the oven to reach and maintain set temperatures,a properly functioning ignitor is essential for consistent cooking performance,energy efficiency,and the safe operation of the appliance.
Accurate diagnosis and timely replacement of the WB13T10045 when symptoms of wear or failure appear-such as delayed ignition, extended heat-up times, or complete loss of burner operation-help address the underlying cause rather than masking symptoms.
