WB13K10043 GE Oven Ignitor Glowbar is a replaceable hot-surface ignitor used in gas ovens; in the first sentence it is identified as the specific part number for a glow-style ignition element. Physically the component is a ceramic or silicon-based resistive element mounted in the oven cavity that heats to a visible orange glow when energized. It is indeed a passive electrical heating device that converts line voltage into thermal energy at the tip to provide ignition temperature for the gas burner. The part is typically supplied as a plug-and-play assembly with mounting bracket and electrical connector matched to GE appliance designs.
Inside the appliance the ignitor is a central element of the gas ignition sequence and interfaces directly with the oven’s control circuitry and the gas safety valve. When the control board calls for heat it delivers current to the ignitor; once the element reaches the required temperature it allows sufficient current flow and often indirectly permits the gas valve to open or satisfies the control logic to initiate gas flow. The ignitor thus interacts with the oven control module,flame-sensing and safety interlocks,and the gas valve assembly; failures or out-of-spec performance can prevent valve operation,trigger safety shutdowns,or produce incomplete combustion conditions.
This article explains how the WB13K10043 functions, how to verify compatibility with specific GE appliance models, and common failure symptoms to watch for such as delayed ignition, no glow, or extended glow time. it covers practical troubleshooting steps including visual inspection, resistance and current checks, and sequence testing with the control board, as well as safe service practices (power and gas isolation) and replacement considerations such as connector type, mounting orientation, and torque/clearance requirements. The goal is to provide technicians, engineers, and appliance owners with the technical background needed to diagnose performance issues and make informed decisions about repair or replacement.

Function and Role of the Oven Ignitor Glowbar in Gas Oven Operation
the WB13K10043 GE Oven Ignitor glowbar is a hot-surface ignitor used to initiate burner operation in manny GE gas ovens. When the oven control applies voltage,the glowbar element rapidly heats to incandescence and provides both the thermal energy to ignite gas and the electrical current path that the gas valve coil senses.The gas valve is designed to open only after the ignitor reaches sufficient emission temperature and the associated current meets the valve’s actuation threshold; if the element is weak or its resistance has changed with age, it may glow yet fail to allow the required current and the valve will not open. Typical failure behaviors include no glow (open element), a dim or slow-to-heat glow (reduced emission), or intermittent operation; each behavior points to different fault modes in the element, wiring, or control circuit and guides subsequent testing and replacement decisions.
Replacing or diagnosing a glowbar requires matching electrical ratings, physical mounting, and connector type so the part functions reliably with the oven’s control and gas valve. Technicians commonly verify element condition with a continuity/resistance check and confirm operational current with a clamp meter during a call for ignition; low measured current under load or an open circuit on the multimeter both indicate the need for replacement. Practical indicators for owners and service technicians include extended preheat times, repeated valve clicking without flame, or visible cracks in the element. When selecting a replacement,confirm that the replacement part’s thermal characteristics,inrush and steady-state current ratings,and mounting geometry match the original to avoid unsafe or unreliable ignition performance.
- No visible glow on call for heat – likely open element or wiring fault.
- Dim or slow-to-heat glow with no ignition – reduced emission, measure running current.
- Intermittent ignition or long preheat – possible marginal element or control timing issue.
- Multimeter reads open or very high resistance – replace the glowbar.

how the WB13K10043 GE Oven Ignitor Glowbar Works Inside the Appliance
The WB13K10043 GE Oven Ignitor Glowbar is a hot-surface igniter that uses a ceramic resistive element to convert mains electrical energy into radiant heat. When the oven control calls for heat, it supplies current to the glowbar; the element heats to a visible orange-white temperature and emits radiant energy that ignites the gas at the burner ports. In parallel, the igniter draws sufficient current so that the gas safety valve is permitted to open; if the element does not reach the required temperature (or draws insufficient current) the valve remains closed and the burner will not light. The glowbar is a direct-fit electrical component mounted at the burner assembly and must match the oven’s mounting and terminal configuration to ensure proper mechanical and electrical compatibility.
- Primary function: provide radiant heat to ignite gas and draw operating current for the gas valve.
- Typical failure behavior: no glow, dim/slow-to-heat glow, or cracked ceramic element causing intermittent ignition.
- Practical checks: visual glow inspection, continuity/resistance measurement, and verifying correct connector/mounting for replacement.
- compatibility note: replace with the matching part number and terminal style to avoid improper fit or electrical mismatch.

| Function | Resistive ceramic element that reaches ignition temperature to light the burner and permit gas valve operation |
In service,technicians evaluate the ignitor’s performance by observing warm-up time and glow intensity and by measuring resistance and current draw; a failing glowbar often causes long ignition delays,multiple shutoff/relight cycles,or no heating at all. For replacement, match the WB13K10043 part number to the oven’s connector type and mounting bracket; during repair, isolate power and gas before removal, and verify the new ignitor reaches full bright glow under normal control voltage before restoring normal operation. These checks help distinguish ignitor faults from downstream issues such as a defective gas valve, control board, or wiring fault.
Common Failure Symptoms and Diagnostic Indicators of Ignitor Degradation
The WB13K10043 GE Oven Ignitor Glowbar is a resistive ceramic heating element that produces the high surface temperature required to open the oven’s gas safety valve and establish a stable flame. In normal operation the glowbar reaches a bright orange state within seconds of a call for heat and draws sufficient current so the valve can energize; compatibility with GE gas oven control sequences means a failing ignitor frequently enough presents as a control-related ignition fault rather than an electrical short. Technicians should treat the glowbar as a load device: simple continuity is a partial check, but verifying visible glow intensity and current draw under operating conditions gives a more accurate assessment of whether the part is still performing to specification.
- Delayed ignition or extended preheat time (ignitor slowly glows or takes much longer than expected to reach full brightness)
- Repeated spark/click attempts without flame or burner cycles that start and stop
- Dim, patchy, or non-uniform glow or visible surface damage such as cracking, blistering, or dark deposits
- Oven heats unevenly or fails to maintain temperature despite the control calling for heat
diagnostic indicators include visual inspection and live measurements: a glowbar that appears dim under power typically fails to draw the required operating current even if it shows continuity on a cold meter. Use a clamp meter or measure voltage drop/current at the ignitor during an ignition cycle to determine if the element is reaching operating temperature; if it glows but does not permit the gas valve to open,the ignitor’s hot resistance or current draw is insufficient and replacement is warranted. For practical troubleshooting,document ignition time,measure continuity and live current,and compare observed behavior to the oven’s specified ignition sequence to isolate whether the issue is the WB13K10043 GE oven Ignitor Glowbar,the safety valve,or the control circuit.
| Item | Description |
|---|---|
| Visual condition | cracks, blistering, or darkening indicate thermal or surface failure affecting performance |
| Operational behavior | Dim glow or long ignition delay under load indicates insufficient current draw |
| Basic electrical check | Continuity might potentially be present on an open-cold meter but fail under operating load; live current measurement is required |
Compatibility, Replacement Considerations, and Troubleshooting Procedures
The WB13K10043 GE Oven Ignitor Glowbar is a resistive ceramic-glass heating element used in gas ovens to heat to ignition temperature and permit the gas safety valve to open. It functions as a current-driven glowbar: when line voltage is applied the element rapidly heats and its resistance rises, and the oven’s control monitors current draw as a proxy for proper element behavior. Compatibility for replacement depends on mechanical mounting, terminal type, and electrical ratings - a correct fit requires matching the ignitor’s terminal spacing, bracket orientation, and the oven control’s expected current characteristics rather than only matching part numbers.Technicians should confirm the physical dimensions and connector style against the oven harness and service manual before assuming interchangeability with other models or aftermarket items.
Troubleshooting focuses on observable behavior and electrical tests. Common symptoms include no glow, slow/dim glow, or intermittent operation; a slowly heating or weak glow typically indicates reduced emission and insufficient current to open the gas valve, while an unlit element with continuity open indicates a failed heater.Practical diagnostic steps include a visual inspection for cracks or flaking, a cold continuity check with a multimeter, and a live-current measurement to verify the ignitor draws the expected running current; if the ignitor glows but the gas valve does not actuate, measure the valve coil resistance and inspect wiring and connections before replacing parts. Follow proper lockout procedures (power and gas off) for disassembly and ensure replacement units match the original’s mounting and terminal configuration to avoid fitment and functional issues.
- No glow / open circuit – likely failed element.
- Slow or dim glow – degraded emission, may not open gas valve reliably.
- Glows but no ignition – check gas valve coil resistance and wiring.
- Confirm fit: terminal spacing, bracket orientation, and thermal insulation.

Q&A
What is the WB13K10043 glowbar ignitor and what does it do?
The WB13K10043 is a GE OEM hot-surface (glowbar) ignitor used in gas ovens. When the oven calls for heat the ignitor heats red-hot and, once it draws the correct current and reaches operating temperature, the oven’s gas safety valve opens and the burner lights. It is not a spark igniter – it relies on heat to ignite the gas.
What symptoms indicate the WB13K10043 is failing?
Common signs of a failing ignitor include the oven not heating at all, long ignition delays (oven tries repeatedly before lighting), the ignitor glowing dimly or not at all, or the oven cycles on then off without maintaining flame. Sometimes the broil function fails while bake still works, depending on wich ignitor is affected.
How can I check whether the ignitor is bad?
Swift checks include a visual inspection for cracks or a broken element and observing whether the ignitor glows brightly when the oven is turned on. For an electrical check, technicians use a multimeter to verify continuity or resistance – a entirely open circuit indicates failure. Becuase this is part of the gas ignition system, longer functional checks and current draw testing are best left to trained service technicians. Always disconnect power and gas before attempting any testing.
Is the WB13K10043 compatible with my GE oven model?
Compatibility is determined by your oven’s model number and the OEM part number. Use your appliance model number to look up replacement parts on GE/Hotpoint/Haier parts sites or reliable parts retailers, or consult your oven’s parts diagram. Do not assume fitment by appearance alone; confirm the WB13K10043 is listed for your exact model.
Can I replace the WB13K10043 myself?
replacement is a relatively common repair, but it involves working with electrical connections and a gas appliance. If you have solid DIY experiance and know how to safely disconnect power and gas, you may be able to replace it. If you are unsure or uncomfortable, hire a qualified appliance technician. Always turn off the circuit breaker and the gas supply before any work, and follow local codes and safety practices.
How long does a glowbar ignitor like WB13K10043 usually last?
life expectancy varies by usage and conditions, but most oven ignitors last several years - commonly 3-10 years. Frequent cycling, power surges, moisture, or mechanical damage can cause earlier failure.
How much does replacing the WB13K10043 typically cost?
Part prices for this OEM glowbar are commonly in the range of roughly $20-$80 depending on supplier. Labor costs for a service call and replacement vary by region and service provider and are often in the $100-$250 range. Obtain a written quote from a parts supplier or technician for an accurate total.
What causes premature ignitor failure and how can I prevent it?
Premature failure can be caused by electrical surges, moisture exposure, repeatedly attempted ignitions (short cycling), or physical damage during servicing. Preventive measures include ensuring proper ventilation, avoiding water exposure, addressing burner or gas-flow issues promptly (which can force extra ignition attempts), and using a qualified technician for service to avoid mishandling.
