5304509706 IGNITOR OEM is an OEM ignitor assembly used to initiate combustion in gas-fired household appliances. As a purpose-built ignition component, it typically takes the form of a hot-surface (glow) element or an electrode-based spark device depending on the specific appliance design; its primary function is to provide the thermal or electrical energy required to ignite the gas supplied to a burner assembly.
Inside an appliance, the ignitor interfaces directly with the burner, the gas valve, and the appliance control circuitry. During an ignition cycle the control board supplies power to the ignitor so it reaches the temperature or produces the spark necesary to light gas when the valve opens; the ignitor also works in conjunction with safety devices such as flame sensors, thermostats, and pressure or flow interlocks to confirm ignition and to allow or inhibit gas flow. Because it is mounted close to the burner and exposed to repeated thermal cycling, its electrical and mechanical characteristics (resistance, current draw, mounting orientation, and connector type) are critical to correct operation and to compliance with the appliance’s safety logic.
In this article readers will find a technical overview of the 5304509706 ignitor’s function and typical electrical and mechanical characteristics, guidance on checking compatibility with appliance models (mounting, connector, and specification checks), common failure symptoms to look for (no ignition, extended glow time, intermittent lighting, visible damage), troubleshooting steps a technician can use (resistance and continuity checks, observation of glow/spark and control signals, and verification of associated gas and safety circuits), and practical replacement considerations (handling fragile elements, matching OEM specifications, and pre/post-installation safety checks). The goal is to provide actionable technical context to help technicians, engineers, and appliance owners diagnose, verify compatibility, and replace the ignitor safely and correctly.

Function and Role of the Ignitor Assembly in Gas Burners and Safety Interlocks
The 5304509706 IGNITOR OEM is a high-voltage spark electrode assembly used to initiate combustion in gas burners by delivering short, kV-level pulses across a precisely spaced gap to ionize the air-fuel mixture. In operation the ignitor is driven by an ignition module or control board that times pulses while the gas valve opens; once the burner lights the system relies on flame detection (flame rectification or a thermocouple/thermopile) to confirm combustion and allow the gas valve to remain energized. The ignitor’s performance depends on correct physical fit, insulation, ground reference, and electrode spacing-incorrect gap, damaged ceramic, or improper mounting commonly produces weak sparks, continuous sparking, or no ignition at all.
- Continuity and connector fit: ensure electrical continuity and correct pinout for the appliance harness.
- Spark gap: typically set to factory specification (commonly around 2-4 mm) for reliable ignition.
- Inspect for cracks/carbon tracking on the ceramic insulator that can shunt voltage to ground.
- Confirm presence of ignition pulses from the control board with a suitable high-voltage probe or diagnostics.
Technicians replacing or diagnosing a 5304509706 IGNITOR OEM should verify mechanical compatibility (mounting hole positions and heat shielding) and electrical compatibility (connector type and control voltage/pulse characteristics) before installation. Practical symptoms that implicate the ignitor include visible arcing at the wrong location, prolonged trial-for-ignition cycles, or complete absence of spark while the control attempts ignition; resolving thes frequently enough requires measuring electrode continuity, restoring the correct gap, securing the ground reference, and confirming the control board issues ignition pulses and recognizes flame via its safety interlocks.

How the 5304509706 IGNITOR OEM Works Inside the Appliance: Ignition Sequence, electrical Characteristics, and Mounting Interfaces
5304509706 IGNITOR OEM serves as the primary ignition element within compatible gas appliances by initiating combustion when the control board calls for heat.In operation the control electronics supply either a sustained drive current to heat a hot-surface element to ignition temperature or a timed high-voltage pulse to a spark electrode; the ignitor’s electrical behaviour (cold resistance, in-circuit current draw, or spark timing) is what the control system monitors before it releases the gas valve. A defective or out-of-spec ignitor will present as an open circuit, excessive resistance, or inconsistent pulse generation, and that condition typically results in valve interlocks, repeated retry cycles, or no ignition at all.
The mechanical and electrical interfaces determine compatibility when replacing the part: common interfaces include stamped mounting flanges with two-screw locations and insulated spade terminals or a dedicated multi-pin harness for the electrical connection.Technicians validate compatibility by matching mounting geometry,connector type,and control logic (hot-surface versus spark) rather than only the part number; bench diagnostics usually involve a resistance/continuity check and observation of drive pulses under powered test conditions. For routine troubleshooting and replacement, always remove power and close the gas supply, confirm connector pinout and mounting orientation, and reassemble so that the ignitor’s hot face or electrode sits in the same relative position to the burner or valve as the original.
- Common symptoms: no spark/glow, long ignition delays, repeated lockout cycles.
- Quick checks: continuity/resistance test, visual inspection of electrode/glow element, verify connector type and secure mounting.
- Replacement guidance: match mounting holes and electrical connector, confirm control board drive type (HV pulse vs. steady current).
| Item | Description |
|---|---|
| Ignition method | Hot-surface glow or timed high-voltage spark depending on appliance design |
| Electrical interface | Drive current or HV pulse; check in-circuit behavior rather than only cold resistance |
| Mechanical interface | Stamped flange or bracket with screw locations; spade terminals or multi-pin harness for electrical connection |
common Failure Symptoms and Diagnostic Indicators: Spark Loss, Resistance Drift, and Intermittent Operation
The ignition module and electrode assembly convert low-voltage control pulses into a high-voltage spark; the 5304509706 IGNITOR OEM is designed to match the original geometry, gap, and electrical interface used on compatible gas appliances. Common failure modes manifest as complete spark loss (no visible arc at the electrode), a weakened or inconsistent arc (weak spark), and measurable resistance drift in the ignitor coil or wiring.Resistance drift typically appears as an upward change from the baseline coil resistance caused by thermal cycling,moisture intrusion,or micro-fractures in the winding or lead solder joints; this alters the current delivered to the spark transformer and can reduce arc energy even when the control module is functioning normally.
- No spark during control pulse (complete open or failed transformer output)
- Weak or short-lived sparks despite clicking (reduced secondary voltage or electrode erosion)
- Intermittent operation that changes with vibration or temperature (lose terminals, cracked insulation, or partial shorts)
- Measured resistance that deviates considerably from service specification (indicates drift or internal winding damage)
| Item | Description |
|---|---|
| Resistance check | Measure continuity and DC resistance across ignitor leads; a sudden high or open reading indicates internal failure or broken lead. |
| Spark observation | Observe arc during a controlled ignition cycle; weak arc suggests reduced transformer output or electrode wear rather than a gas supply fault. |
| Intermittency test | Wiggle wiring and warm/cool the assembly to reproduce intermittent faults,and inspect connectors for corrosion or loose crimps. |
Technicians should combine visual inspection, multimeter resistance checks, and live spark observation to isolate the fault: begin with a DC resistance measurement and connector inspection, then verify that the control board supplies the correct pulse and that the ignitor produces a stable arc. For example, a stove that clicks repeatedly but produces no flame often has either an open ignitor winding, a shorted secondary path caused by carbon tracking on the ceramic, or a connector with intermittent contact; swapping in a known-good ignitor or temporarily bridging the connector (with proper safety precautions) can distinguish component failure from control-board output issues. When replacing the unit, match the electrical interface, mounting and gap geometry to ensure compatibility with the appliance’s transformer and control timing.
Compatibility, Replacement Considerations and Installation Procedures with Troubleshooting protocols for service Technicians
The 5304509706 IGNITOR OEM is a durable glow-type ignitor used primarily in gas ranges and ovens to initiate burner ignition by heating to a temperature that reliably opens the gas valve sequence on appliance control modules. Functionally it converts electrical energy into heat at a precisely located ceramic/glass element; compatibility depends on the ignitor’s terminal type (spade vs. pigtail), physical mounting bracket, and electrical characteristics. before replacement, compare the OEM part number, connector style, lead length, and measured cold resistance against the service data for the appliance: verify that the ignitor mounts into the same bracket, that the control board supplies the same drive voltage, and that the wiring harness matches, otherwise the control or safety interlocks may not engage correctly.
Installation and troubleshooting follow deliberate safety and diagnostic protocols: disconnect power and gas, remove the burner assembly, replace the ignitor with identical orientation and secure mounting to avoid heat conduction to nearby components, then restore power and verify the ignition sequence. Typical diagnostic checks include measuring element continuity and cold resistance with a multimeter, observing the element glow time and color, and confirming the control board sends the expected ignition voltage and correctly senses flame presence. Common symptoms and quick checks are listed below to guide technicians during service.
- No glow from ignitor: check supply voltage at connector, measure element resistance for open circuit.
- Glow but no gas ignition: verify gas valve operation and flame sensor continuity; check burner ports for blockage.
- Intermittent ignition or long glow time: inspect mounting for heat sink issues, replace if element shows high resistance drift.
- Physical damage or cracks: replace ignitor and re-check alignment to prevent uneven heating.
| Item | Description |
|---|---|
| Expected behavior | Element reaches visible orange glow within designed time and control board confirms flame signal. |
| Common failure mode | Open circuit due to filament break, cracked ceramic, or thermal degradation from improper mounting. |
| Service test | Measure cold resistance (compare to OEM spec),confirm drive voltage during start sequence,inspect mounting and connector continuity. |
Q&A
What is the 5304509706 ignitor OEM and what appliances use it?
The 5304509706 is an OEM (original equipment manufacturer) hot surface or glow ignitor used on gas appliances (most commonly ovens, ranges, and some gas furnaces).OEM means it is indeed the factory part intended for the original appliance models. To confirm fit,always cross‑check the part number with your appliance model number or the manufacturer parts list.
What are common symptoms that the 5304509706 ignitor is failing?
Common symptoms include no ignition (no glow or no flame), a weak or dim glow, long pre‑ignition delay, repeated attempts to light then lockout, or the appliance’s safety valve not opening even when the ignitor glows. You may also notice a clicking relay or repeated cycles without flame.If you smell gas, treat it as an emergency and shut off gas and power instantly.
How can I test the 5304509706 ignitor to see if it is bad?
First, cut power to the appliance.A basic check is a continuity/resistance measurement across the ignitor with a digital multimeter: a healthy cold hot‑surface ignitor usually shows continuity and a relatively low resistance (values vary by model; consult the appliance spec sheet). An open circuit (infinite resistance) means it is failed. A functional test while the unit is calling for heat: with appropriate safety precautions, check that the ignitor receives line voltage (commonly ~120 V on many appliances) and that it glows brightly. If it receives voltage but does not glow, it is indeed bad. If it glows weakly but the gas valve doesn’t open, the ignitor may be too weak (worn) to create the necessary current to operate the gas valve.
Can I replace the 5304509706 ignitor myself, and what are the basic steps?
Qualified DIYers can replace it, but follow safety precautions. Basic steps: 1) Turn off electrical power and gas to the appliance. 2) Access the ignitor by removing the appropriate panel(s). 3) Take note or photos of mounting and wiring, then disconnect the ignitor wires (power leads). 4) Remove mounting screws and carefully remove the old ignitor-the element is fragile. 5) Install the new OEM ignitor, secure it, reconnect wiring, restore panels, then restore power and gas and test operation. If unsure at any point, or if the appliance is a gas furnace with complex controls, hire a licensed technician.
Are there special safety or handling precautions when installing this ignitor?
Yes. always turn off electrical power and gas before working on gas appliances. Handle the ignitor element carefully-do not touch the ceramic or the hot surface with bare hands,as oils from skin can shorten its life. The element is fragile; avoid impact. Ensure wiring is properly connected and insulated. After installation, confirm there are no gas leaks and that the appliance cycles correctly. If you smell gas at any time, stop and contact your gas supplier or a qualified technician.
What’s the difference between buying the OEM 5304509706 versus an aftermarket ignitor?
OEM parts are made to the appliance manufacturer’s specifications and typically guarantee a direct fit and performance consistent with the original. Aftermarket parts may be less expensive but can vary in quality, fit, and longevity. If you want guaranteed compatibility and original performance,choose the OEM part; if cost is a concern,verify the aftermarket part’s specifications and reviews before buying.
How long does the 5304509706 ignitor usually last and what causes premature failure?
Lifespan varies widely-many ignitors last several years but can fail prematurely due to mechanical shock, oil or fingerprints on the element, voltage spikes, repeated power cycling, or manufacturing defects. Frequent cycling or poor electrical supply can shorten life.Proper handling during installation and stable electrical supply help maximize service life.
I replaced the ignitor with a 5304509706 but the appliance still won’t light-what should I check next?
Verify that the new ignitor gets the correct supply voltage when the unit calls for heat (use a meter safely). Check the gas supply and that the gas valve and gas safety controls are functioning-if the ignitor glows but the valve does not open, the valve or control system may be faulty. Also inspect wiring, connectors, limit switches, thermostats, and control boards for faults. If you’re not agreeable with these electrical and gas checks, call a qualified service technician to diagnose and repair.
