WB13K10043 GE Oven Ignitor Glowbar is a replaceable ceramic-glass heater element used as the primary ignition source in many GE gas ovens and ranges. As a glowbar-type ignitor, it contains a resistive filament encased in a high-temperature ceramic or glass envelope that converts electrical energy into radiant heat; when installed it mounts adjacent to the oven burner tube or manifold to provide a concentrated heat source for gas ignition. This component is a mechanical/electrical part rather than a regulator or valveand it is specified by exact part number and connector type to match the appliance model and mounting configuration.
Inside the appliance, the glowbar is part of the oven’s ignition subsystem and interfaces electrically with the oven control module and mechanically with the burner assembly. When energized, the ignitor heats to a red‑hot glow that delivers the thermal energy necessary to ignite gas released by the oven’s gas valve; the control board monitors the ignitor’s electrical characteristics and timing to determine whether the valve can be opened safely. The glowbar also connects to the wiring harness and mounting brackets,and its proper operation affects ignition timing,burner light‑off reliability,and overall safety interlocks implemented by the control electronics.
In this article readers will find a technical overview of the WB13K10043’s operating principle and typical installation locations, guidance on compatibility and identifying the correct replacement, common failure symptoms (such as extended glow time, no glow, intermittent ignition or open circuit indications)and the diagnostic checks and replacement considerations a technician or informed appliance owner shoudl evaluate. coverage includes how the ignitor interacts with the gas valve and control circuitry, what diagnostic measurements and visual inspections are relevantand practical factors to consider when selecting and installing a replacement part to restore reliable oven operation.

Function and Role of the Oven Ignitor in Gas Valve Control and Oven Temperature Regulation
The WB13K10043 GE Oven Ignitor Glowbar is a resistive glow-type ignitor that serves as both the heat source to ignite gas and the current-producing element that enables the oven gas valve to open. In operation the control board supplies mains voltage to the glowbar; as the element heats it reaches a predetermined incandescence and draws the necessary current so the gas safety valve will actuate and admit gas to the burner. If the ignitor’s resistance is too high or the element cannot reach the required temperature, the valve will not open or the controller will delay gas delivery, producing long ignition cycles or no ignition at all. The timed relationship between glow temperature, current draw, and valve actuation is what determines reliable ignition and stable oven temperature control.
Compatibility for replacement requires matching electrical characteristics (voltage rating and expected current draw),connector type,and physical length/mounting so the ignitor produces the same heat-up profile as the original; an incorrect replacement can cause slow ignition,flame instability,or repeated safety lockouts. For practical diagnostics a technician typically checks cold resistance with a multimeter and compares it to the manufacturer’s specand may perform an in-circuit amperage check during heat-up to verify the ignitor draws expected current.Typical service symptoms, test cues, and a concise technical reference follow to assist troubleshooting and part selection.

How the WB13K10043 GE Oven Ignitor Glowbar Works inside the Appliance: Electrical Characteristics and Thermal ignition Process
The WB13K10043 GE Oven Ignitor Glowbar is a resistive ceramic glowbar that converts line voltage into heat to produce an incandescent ignition surface for gas burners. Electrically the part behaves as a temperature-dependent resistor: at room temperature it presents a measurable cold resistance and, when connected to 120 VAC, conducts several amps to heat the ceramic element until it reaches incandescent temperature. As the element warms its resistance rises (a positive temperature coefficient), which slightly reduces current as the surface reaches operating temperature; the sustained current draw prior to flame establishment is also the signal used by most oven safety gas valves to permit gas flow. Technicians diagnosing ignition problems commonly measure cold resistance with a multimeter and observe warm current draw with a clamp meter to confirm the ignitor is both electrically intact and drawing within the expected range.
- Apply mains voltage → glowbar heats and begins to emit visible incandescent radiation.
- Heating raises element resistance while maintaining sufficient current to actuate gas valve coils.
- Gas flows and the glowing surface ignites the gas; once flame is established, the ignitor continues to cycle to maintain ignition until the thermostat or controller stops heat demand.
- Failure modes include open circuit, excessively high cold resistance, slow heat-up (reduced current)or mechanical damage that prevents correct mounting or gas-flame exposure.
The thermal ignition process depends on the glowbar reaching a threshold surface temperature fast enough to ignite the gas stream; slower warm-up times or lower peak temperatures produce delayed ignition, repeated sparkingor safety valve lockouts. For practical compatibility, replacement WB13K10043 assemblies should match the original part’s electrical characteristics (cold resistance and rated current), connector typeand mounting orientation so the element sees the correct gas flow and flame pattern; using an ignitor with lower current draw can prevent the safety valve from opening and using one with incorrect mounts can cause improper flame impingement and premature failure. Common troubleshooting steps include measuring cold resistance, observing warm current and glow timeand confirming secure electrical and mechanical connections before replacing the part.
| Item | Description |
|---|---|

Common Failure Symptoms, Measured Resistance and Current Valuesand Diagnostic Indicators
The WB13K10043 GE Oven Ignitor Glowbar is a hot-surface ignitor that heats to a high temperature and draws current sufficient to allow the gas safety valve to open. In service it should glow shining orange within a few seconds of a call for heat and sustain that glow until the burner lights. This part must match the oven’s electrical and thermal characteristics; using an ignitor with significantly different resistance or heat-up time can prevent the gas valve from seeing the required current and will cause ignition failure even if the control and valve are functional. Technicians should confirm fit and terminal configuration as part of compatibility checks before replacement.
Diagnostics rely on simple electrical checks and observation. Measure resistance across the ignitor terminals with the unit at room temperature; typical cold (room-temp) resistance for many GE-style glowbar ignitors falls in the approximate range of 30-100 Ω,and when operating on a 120 V circuit the element commonly draws around 2.5-3.5 A.Key failure indicators include an open circuit (infinite resistance), a cold resistance substantially higher than the expected range, an ignitor that glows very dim or takes excessively long (for example, more than 30-45 seconds) to reach full glowand measured current under load that is below about 2 A. If the ignitor measures within expected resistance but the oven still does not ignite, measure supply voltage during a call for heat – absence of ~120 VAC indicates a control or wiring fault rather than the ignitor itself.
- No visible glow or an open-circuit reading on a multimeter – replace ignitor.
- Dim or slow-to-glow element with high cold resistance – indicates degradation; expect longer heat-up time and possible replacement.
- Proper glow but low measured current (< ~2 A) during operation – check supply voltage and gas valve circuit.
- Visible cracks or flaking ceramic – mechanical damage necessitates replacement.
| Item | Description |
|---|---|
| Cold Resistance (typical) | Approximately 30-100 Ω measured across terminals at room temperature; values outside this range suggest wear or type mismatch. |
| Operating Current | Approximately 2.5-3.5 A on a 120 VAC circuit; sustained current below ~2 A usually fails to open the gas valve. |
| Glow Time | Full bright glow typically within 10-30 seconds; longer times indicate reduced heater efficiency. |
| Visual/physical | Cracks, flakingor broken leads are clear indicators for replacement nonetheless of resistance reading. |
Compatibility, Replacement Considerations, and Safe Installation Procedures for WB13K10043 and Equivalent Ignitor Assemblies
The WB13K10043 GE Oven Ignitor Glowbar is a hot-surface ignitor that functions as the primary heat source to initiate gas flow in many GE gas ovens.The glowbar must reach a target temperature and corresponding current draw so the oven’s gas valve and safety interlocks allow gas to flow; if the ignitor is weak or its cold resistance is out of spec, the valve will not open or the oven will cycle without producing a stable flame. compatibility hinges on matching the ignitor’s electrical and mechanical characteristics - operating voltage, connector type and harness length, mounting footprintand cold-resistance range – because an otherwise identical-looking element can fail to energize the valve or can overstress the oven’s control circuit if those parameters differ. Technicians typically verify a candidate replacement by measuring cold resistance, confirming connector compatibilityand reviewing installation geometry before committing to a substitute part number.
Replacement and safe installation require purposeful checks and procedures to avoid damage to the glowbar and to ensure safe ignition behavior after service.Avoid handling the ceramic/glow surface with bare hands because oils can create hot spots and shorten life; verify the new assembly’s resistance and harness polarity (where applicable) on the bench before final mounting, and use only parts that match the oven’s required electrical rating. After installation, test for correct current draw during warm-up and confirm a steady, full-flame ignition across multiple cycles; if ignition is slow or the control opens and closes the gas valve repeatedly, re-check wiring, resistanceand the condition of the gas valve and safety sensors.
- Safety and verification steps: disconnect electrical power and gas supply, confirm part number and mounting alignment, measure cold resistance, avoid contact with the ceramic element, secure wiring/harness strain reliefand leak-test gas connections after reassembly.

Q&A
What is the WB13K10043 GE Oven Ignitor Glowbar and what does it do?
The WB13K10043 is a hot-surface ignitor (glowbar) used on many GE ovens and ranges. When the oven calls for heat the ignitor heats (glows) to a high temperature; its current draw allows the gas safety valve to open and the burner to light. It is not a spark igniter-ignition occurs from the hot surface contacting the gas stream.
What are the common symptoms that the WB13K10043 ignitor is failing?
Common signs include: the ignitor does not glow at all, it glows very dimly or takes much longer than normal to glow, the oven takes a long time or never reaches set temperature, the bake/broil burners click or attempt to light but will not stay on, or the burner lights then goes out. These symptoms usually indicate the ignitor cannot reach the required temperature or current to open the gas valve.
How can I test the ignitor with a multimeter to see if it’s bad?
With power disconnected and the ignitor disconnected from the wiring harness, set the multimeter to the ohms (Ω) range and measure across the ignitor leads. A good ignitor will show continuity (a finite low resistance). An open circuit (infinite resistance) means the element is failed. For a definitive diagnosis you can also measure current draw during operation (by a qualified technician): many hot-surface ignitors require roughly 3-3.6 amps to open the gas valve, but check the oven’s service literature for the exact spec.
Can I replace the WB13K10043 myself,and what are the basic steps?
Yes,an experienced DIYer can replace it,but always prioritize safety. Basic steps: 1) Disconnect electric power to the oven and turn off the gas supply. 2) Remove oven racks and access the burner/ignitor area (may require removing the bottom panel). 3) unplug or disconnect the ignitor wires (note connector orientation). 4) Remove mounting screws and carefully remove the ignitor-the ceramic element is fragile. 5) Install the new WB13K10043 without touching the ceramic with bare hands, secure it, reconnect wiring, restore power/gas, and test. If you’re unsure at any point,hire a technician.
Are there any safety or handling precautions I should follow when installing it?
Yes. Always disconnect electrical power and shut off the gas before working on the oven. the ignitor’s ceramic/glass surface is brittle-do not touch it with bare fingers (oils can shorten lifespan) and avoid bending or striking it.After installation check for gas leaks at any fittings you disturbed.If you smell gas or are not confident, contact a professional.
How do I know the WB13K10043 is compatible with my oven model?
WB13K10043 is a commonly used GE replacement part for many GE/Hotpoint/Jenn-Air ranges, but compatibility depends on the oven’s model and mounting/connector style. Confirm compatibility by checking your appliance model number against the part cross-reference (manufacturer’s parts list or authorized parts dealer) or by matching the old part’s shape, mounting holes and connector. Do not assume fitment without verification.
What else could cause ignition problems if the ignitor tests good?
If the ignitor has good continuity and proper current draw but the burner still won’t light or stay lit, possible causes include a failing gas safety/solenoid valve, a faulty oven control board or thermostat, bad wiring or a loose connectoror a clogged burner or gas orifice. A technician can perform voltage/current diagnostics and inspect the gas valve operation to isolate the issue.
How long does a WB13K10043 ignitor typically last and what shortens its life?
hot-surface ignitors ofen last several years (commonly 3-7 years) but lifespan varies with usage. Factors that shorten life include physical shock, handling that contaminates or damages the ceramic, moisture exposure, electrical surgesand manufacturing variability. If an ignitor fails prematurely after installation, check for installation stresses, wiring issuesor environmental factors that could be contributing.
To Conclude
The WB13K10043 GE oven ignitor glowbar serves as the primary ignition component in many gas ovens, producing the heat necessary to open the gas valve and initiate stable combustion.As it directly affects burner ignition, bake accuracyand overall appliance safety, a properly functioning ignitor is essential to reliable oven performance and energy-efficient operation.
Accurate diagnosis and timely replacement of a failing WB13K10043 are critically important to avoid prolonged downtime, inefficient cookingand potential safety concerns. Confirming the ignitor as the root cause-rather than other ignition or gas-system faults-and installing the correct replacement part helps restore oven performance and maintain manufacturer specifications. When in doubt, engaging a qualified service technician ensures safe testing and proper installation, protecting both the appliance and the home.
