WB13K10043 GE Oven Ignitor Glowbar is a hot surface ignitor – a ceramic-encased resistive heating element designed to reach incandescent temperatures to ignite gas in residential ovens and ranges. As a glowbar-type ignitor, it converts electrical energy into radiant heat rather than producing a spark; its construction and electrical characteristics are selected to provide consistent heat-up time and mechanical fit for specific GE appliance models.
Inside a gas oven the WB13K10043 functions as the primary ignition source for the bake or broil burner and forms an integral part of the appliance’s ignition and safety circuits. When powered, the ignitor heats to a temperature sufficient to ignite the incoming gas; the resulting current draw and temperature also enable or trigger the gas valve and control board to allow gas flow. The ignitor thus interacts directly with the burner assembly, gas safety valve, wiring harness, and the oven control/thermostat logic; variations in its resistance, heat-up time, or physical alignment can affect ignition reliability, preheat time, and flame stability.
In this article you will find a technical overview of the WB13K10043’s operating principles, guidance on model compatibility and cross-referencing, common failure symptoms (for example failure to glow, slow heat-up, prolonged ignition cycles, or oven not heating), step-by-step troubleshooting methods (visual inspection, resistance and voltage measurements, and current/load checks), and practical replacement considerations including mounting, connector type, and safety precautions. The focus is on diagnostic techniques and installation details that a technician, engineer, or educated appliance owner can use to verify component condition and perform a safe, effective replacement when necesary.

Function and Role of the WB13K10043 GE Oven Ignitor glowbar in Gas oven Ignition Systems
WB13K10043 GE Oven Ignitor Glowbar is a hot‑surface ignitor used in GE gas ovens to provide the heat source and the electrical behaviour required to initiate combustion. Electrically driven from the oven control, the glowbar heats to visible red‑hot temperatures; its material (a high‑temperature semiconductor ceramic) changes resistance as it warms, producing the required current profile that the safety gas valve and control circuitry monitor. In the ignition cycle the control supplies line voltage to the glowbar until the element reaches its operating temperature and the resulting current draw meets the valve’s activation threshold, at which point the gas valve is energized and the glowing element ignites the gas stream.
Failure modes are typically thermal or mechanical: a cracked or aged glowbar will either fail to reach ignition temperature or will not present the correct electrical characteristics, causing long glow times or a complete lack of ignition.Technicians use a multimeter to check for open circuit or out‑of‑range cold resistance and an ammeter to verify in‑circuit current during start-up; replacement requires matching the WB13K10043 GE Oven Ignitor Glowbar to the oven’s connector, mounting orientation, and rated voltage to restore correct ignition timing.Practical field considerations include verifying harness connectors and bracket fit before installation and observing that flame establishment occurs within the manufacturer’s specified pre‑ignition interval after replacement.
- no flame while ignitor glows, or continuous long glow before ignition
- Open circuit or considerably higher cold resistance on multimeter test
- Intermittent ignition or slow warm‑up indicating degraded element life
- Must match connector, bracket, and voltage rating for direct replacement

How the Glowbar Works Inside the appliance: Thermal, Electrical, Resistance Profiles and Mounting Interfaces
The WB13K10043 GE oven Ignitor Glowbar operates as a resistive hot-surface igniter: when 110-120 VAC is applied the ceramic-glass resistive element conducts and converts electrical energy to heat, producing a visible orange/white glow that brings the adjacent burner manifold to ignition temperature. As the element heats its resistance rises, which reduces current draw from the supply; the oven control monitors that current/voltage signature as a proof-of-heat signal to permit the gas valve to open. Inside the appliance the glowbar’s thermal mass, radiation pattern, and proximity to the gas ports determine ignition reliability, so proper orientation and clearance are critical for consistent ignition timing and flame establishment.
Resistance profile and mounting interface determine both compatibility and field-service diagnostics. Measure cold resistance with the power removed and the element cooled; typical cold resistance for similar GE oven glowbars falls roughly in the 40-120 Ω range and should present a low, finite value rather than open circuit. Mounting varies by model-common interfaces are a stamped steel bracket with two screw holes and insulated spade terminals or a ceramic terminal block-so technicians must match the bracket location, terminal type and lead length when replacing the ignitor. Practical checks include verifying cold-ohm value, confirming the element glows under applied mains before the gas valve is energized, and inspecting the mounting for secure mechanical contact and correct clearance.Symptoms a technician will observe with a degraded or mismatched ignitor include no glow (open element), slow or dim glow with delayed ignition (high resistance or poor electrical connection), and intermittent operation caused by loose mounting or brittle leads.
- No glow / open-circuit on ohmmeter
- Dim or slow-to-heat glow indicating higher-than-normal resistance
- Intermittent ignition related to loose bracket or crimped terminals
- Correct electrical signature (approx. 2-3 A at nominal voltage when hot) permits gas valve actuation

| Mounting interfaces | Stamped bracket with screws and insulated spade or ceramic terminal block-verify lead length and bracket orientation for fit |
Common Failure Symptoms and Diagnostic Procedures for Ignitor Glowbar Faults
The WB13K10043 GE Oven Ignitor Glowbar is a resistive ceramic-and-filament ignitor that must heat to a visible orange glow to allow the oven’s gas valve to open and sustain a burner flame. Typical failure modes manifest as a visibly weak or slow-to-heat element, a cracked or carbonized ceramic surface, or an open filament; these conditions prevent the ignitor from drawing sufficient current to operate the gas valve or can cause intermittent ignition. Compatibility checks are practical: confirm the glowbar’s mounting dimensions and two-pin connector match the oven harness and that the replacement matches the original part orientation, because an otherwise electrically functional ignitor can still fail to operate if it cannot be mounted or connected correctly in the oven’s burner assembly.
- No glow or complete open circuit at the ignitor leads.
- Dim or slow-to-shining glow with long ignition delay (oven clicks, then no flame).
- Intermittent ignition or flame loss after initial light-up.
- Visible cracks, blistering, or blackened ceramic on the glowbar surface.
| item | Description |
|---|---|
| Cold continuity | Check with a multimeter for continuity; an open reading indicates a failed filament. |
| Typical resistance (cold) | Referential range: approximately 30-100 Ω (varies by model); significant deviation suggests deterioration. |
| Operating behavior | Element should reach steady orange glow within 15-60 seconds under rated line voltage; much longer indicates reduced current draw. |
Diagnose failures by first performing a visual inspection for physical damage and connector integrity, then verify electrical behavior.Use a multimeter to check for continuity and approximate resistance across the two ignitor terminals; an open circuit or a resistance far outside the reference range supports replacement. If continuity is present, measure line voltage delivered to the ignitor during a normal ignition cycle and, if available, use a clamp ammeter to confirm current draw meets the oven’s service specifications-low current or slow warm-up indicates a weak ignitor even if it shows continuity. For practical troubleshooting, isolate the ignitor and controls: substitute a known-good ignitor or check the control board and gas valve separately to rule out harness or control faults before replacing the WB13K10043 GE Oven Ignitor Glowbar.
Compatibility, Model Fitment, and Replacement Considerations: Connectors, Mounting, and Safety Requirements
WB13K10043 GE Oven ignitor Glowbar is a resistive ceramic-glass element that must match the oven’s electrical and mechanical interfaces to operate reliably. Functionally it draws line voltage from the oven control/gas valve circuit and converts electrical energy into heat until the flame-opening temperature is reached; therefore compatibility is defined by terminal type, mounting footprint, and the element’s thermal/electrical characteristics. Before replacing an ignitor, confirm the replacement matches the original connector style (such as two insulated 1/4″ spade terminals versus a molded multi-pin harness), the flange or bracket hole spacing, and that the part’s physical length and orientation place the glowing element in the correct position relative to the burner ports so it provides both ignition heat and any required flame-sensing exposure.
Practical replacement considerations include secure high-temperature wiring connections, preserved clearance from metal parts and insulation, and adherence to safety steps such as disconnecting electrical power and shutting off the gas supply before servicing.technicians should compare the old ignitor’s electrical behavior to the replacement-visual fit and connector match are necessary but not sufficient-by verifying continuity, inspecting for cracked ceramic or damaged insulators, and confirming the control circuit supplies the correct operating voltage and current during a bench test or controlled in-situ test. Common checks and actions include:
- Verify part number, terminal type, and flange hole spacing against the original assembly.
- Inspect and, if needed, replace the wiring harness, high-temp insulation, and mounting gaskets.
- Measure continuity and compare resistance to the old part and manufacturer data; perform a controlled live test only after power/gas are isolated and safety measures are in place.
| Item | Description |
|---|---|
| Terminal | Two insulated spade terminals or specific harness; must match oven harness for secure connection. |
| Mounting | Flange/bracket hole spacing and element projection determine correct placement relative to burner. |
| Safety | Power and gas off during replacement; use high-temp rated connectors and restore gasketing to prevent heat damage. |
Q&A
What is the WB13K10043 oven ignitor glowbar and what does it do?
The WB13K10043 is a replacement glowbar (hot surface) ignitor used on many GE gas ovens. When the oven calls for heat the control sends voltage to the ignitor; the glowbar heats to a bright orange and,after it reaches the required temperature/current draw,the gas safety valve opens and the burner lights. It is an OEM-style hot-surface ignitor designed to replace a failed original ignitor.
What are common symptoms that the WB13K10043 needs replacing?
Common symptoms include the oven not heating or taking a very long time to light, the ignitor not glowing at all, a very weak or dull glow, or the oven clicking with no flame. A weak ignitor may glow but fail to draw enough current to open the gas valve, causing delayed or no ignition. Sooting or visible cracks on the ceramic or element are also signs it should be replaced.
How can I test the ignitor to confirm it is faulty?
Start by cutting power to the appliance and removing the oven access panel to reach the ignitor. For a basic electrical check use a multimeter: with power off, check for continuity across the ignitor leads – an open circuit indicates failure. For an operational check (only if comfortable and observing safety): restore power and start a bake cycle while observing the ignitor; it should glow bright orange within 30 seconds and the burner should light shortly after. A glow that is dim or slow to heat often indicates the ignitor is weak and should be replaced. If unsure, compare measurements to the oven’s service manual or consult a technician.
Can I replace the WB13K10043 myself and what are the basic steps?
Yes, a competent DIYer can usually replace it. Basic steps: 1) Turn off electrical power at the breaker and shut off the gas supply. 2) Remove the oven floor or access panel to access the ignitor assembly.3) Disconnect the ignitor wiring (note or photograph connections), remove the mounting screws and carefully withdraw the old ignitor. 4) Install the new ignitor (handle by the base-avoid touching the ceramic/glow surface), secure the mounting screws, and reconnect the wires. 5) Reinstall panels, restore gas and power, and test. Wear gloves and take care not to break the brittle glowbar. If you’re uncomfortable working with gas or electrical components, hire a qualified technician.
Do I need to worry about touching the new ignitor with my hands?
Yes. Oils and dirt from your fingers can create hot spots on the ceramic and shorten the ignitor’s life. Handle the glowbar by its metal base or wear clean gloves when installing, and avoid touching the ceramic or glass surfaces.
How do I confirm that WB13K10043 is compatible with my oven model?
Check the oven’s model number (usually on a tag around the oven door frame or behind the storage drawer) and compare it with the OEM part number list from GE or an authorized parts dealer. You can also enter your oven model on the manufacturer’s parts website or contact customer support. Do not rely solely on visual similarity-confirm the part number and connector type match before buying.
could something else be causing my oven not to ignite besides the ignitor?
Yes. Other possible causes include a defective gas safety valve, faulty thermostat or control board, bad wiring or connectors, a tripped safety device, or blocked burner ports. If the ignitor checks out (continuity and proper heating) but the burner still won’t light, further diagnosis of the gas valve and control circuitry is needed, frequently enough by a trained technician.
How long does a replacement ignitor typically last and how challenging/expensive is the repair?
Ignitor life varies with usage but many last several years; factors include usage frequency and handling. The repair is generally considered moderate in difficulty, takes roughly 15-45 minutes for someone comfortable with appliance repairs, and the part cost is moderate compared with other oven components. If you are unsure about safely handling gas and live electricity, budget for a service call by a qualified appliance technician.
Insights and Conclusions
The WB13K10043 GE oven ignitor glowbar serves as a critical component in gas oven operation by producing the high-temperature glow required to ignite the burner. Its reliable function directly affects oven performance, cycle times, fuel efficiency and overall safety; a degraded or failed ignitor can cause incomplete ignition, extended preheat times or unsafe operating conditions.
Because symptoms of ignitor problems can resemble other appliance issues, accurate diagnosis is important before replacing the part.Visual inspection and basic electrical checks can indicate a failing glowbar, but confirming compatibility with the WB13K10043 specification and following manufacturer guidance are essential.When replacement is necessary, using the correct OEM or equivalent part and ensuring proper installation-preferably by a qualified technician-helps restore safe, efficient oven operation and reduces the risk of further damage.
