5303935067 Frigidaire Range Flat Oven Ignitor 3-1/4″ is aâ hot-surface ignitionâ element designed for Frigidaireâ gas ranges that uses a flat, low-profile ceramic heating element to achieve the âtemperature necessary to ignite oven burner gas. The âcomponent is a resistive heating element assembled with a mounting⢠bracket âand electrical terminals, sized at 3-1/4″ to fit specific burner locationsâ and housings. As aâ replaceable service part, it is built to withstand repeated thermal cycling andâ mechanical mounting constraints typicalâ of range oven cavities.
Inside the appliance the ignitor is a core âpart of the gas ignition system: when energized it glows to provide the thermal energy and, in many⤠control designs, the electrical current draw that â˘allows theâ gas â¤valve to open. It interfaces directly with the oven â¤control/ignition circuit, the wiring harness and the valve assembly, â˘and it is typically mounted adjacent to the oven âburner so the glowing⣠element can reliably ignite the gas stream. Because the control system often monitors ignitor current or resistance as a safety criterion, the ignitor’s condition affects both ignition timing and â˘the valve interlock logic⢠used to prevent unsafe gas⣠flow.
This article will⣠provide a technical overview of âthe 5303935067 ignitor’s function and construction, explain the range models and installation locations where this⤠flat 3-1/4″ âŁelement is typically â˘usedand describe common failure symptoms such as no ignition, extended preheat timeor visible cracking. It will outline diagnostic checkpoints useful to technicians and informed âŁowners-covering compatibility checks, basic electrical and âŁcontinuity checks used during troubleshootingand practical replacement considerations including matching length, âmounting style,⤠and connectorâ type. â¤Safety â¤andâ proper part âselection will be emphasized to helpâ ensure reliable operation âŁafter âservice.

Function and Role âof the Flat Oven Ignitor in⣠Frigidaire Gas Range Ignition Systems
The 5303935067 Frigidaire Range flat Oven Ignitor 3-1/4″ is a âhot surface ignition âelement designed to⤠produce the thermal energyâ necessary to allow the oven’s⣠gas safety valve to open. Electrically, the ignitor is wired into the control circuit and, when suppliedâ with line voltage, heats to an⢠incandescent temperature; as âŁit reaches its operating temperature the electrical characteristics change and the resulting⤠current draw permits â¤the gas⣠valve to â¤energize âand release fuel. Proper function depends onâ the ignitorâ reaching its designed surface temperature within a predictable time window and matching the physical mounting,connector type,and thermal coupling âspecified for the range model so the âvalve senses the correct loadâ beforeâ gas⢠flow begins.
- Common⤠failure behaviors: slow heat-up, dim glow,â open circuit,⣠or⢠intermittent operation âresulting⤠in no gas flow.
- Compatibility checks: length (3-1/4″), terminal type,⤠mounting bracket positionand harness mating continuity.
- Practical test cues: consistent glow within the â˘expected time and stable current draw; deviationâ suggests âweakened element or improper installation.
In the ignition system the ignitor functions as both a timing element and a load sensor:⤠its warm-up âcurve establishes the delay between call-for-heat and gas releaseand its resistance/temperature profile provides⢠the âelectrical signature the gas valve or control board expects. Replacement with an incorrect profile â(different length, wattage,â or connector) can âcause delayed ignition, continuous glow âwithout valve actuationor premature service lockouts. Technicians typically evaluate the âŁignitor alongside wiring, the safety valveand control outputs; restoring original performance usually requiresâ a direct replacement that matches⣠the electrical and mechanical parameters of the failed component so the oven returns to its âdesigned thermal and⢠electrical behavior.

How the 5303935067 Frigidaire âŁRange Flat Oven âIgnitor 3-1/4″ Operates within the Oven’s⢠Gas Control Circuit
The 5303935067 âFrigidaire Range flat Oven ignitor 3-1/4″ âisâ a resistive, flat-surface ignition element that functions as the current-sensing heater in the oven’s gas control circuit. When the⣠oven control applies lineâ voltage to the ignitor, âthe element heats and begins to emit electrons (visible as a luminous orange glow). That emission creates âŁthe necessaryâ current draw through the safety interlock circuit so the oven⤠gas valve can actuate; until the ignitor draws sufficient current,⢠the gasâ valve remains⣠closed.This part is⢠intendedâ as a like-for-like replacement on Frigidaire ranges that use the flat-style ignitor and is dimensioned and terminated âto match the originalâ mounting and connectorâ arrangement for proper electrical and mechanical compatibility.
Electrically the ignitor behaves like a temperature-dependent resistor: â¤it initially draws higher current as it heats and then settles when âit âreaches operating temperature. â¤In practical service, common⣠failure modes are open circuit (no glow), reduced emission (glows weakly⢠or takes much longer to reach full brightness),⤠and intermittent connections at the terminal or mountingâ bracket. âAâ weak or degraded ignitor will often cause long preheat times or⣠a failure of the gas valve to open even though the ignitor glows; technicians⤠verify performance by observing glow âŁtime and measuring current âdraw with a clamp meter â˘or measuring continuity to confirmâ expected behavior. For field context,â replacing a degraded unit⤠with the⢠correct 5303935067 ignitor typically ârestores the intended current profile and reliable valve actuation, provided the gas valve and control â¤circuitry are functional.
- Function: âŁresistive heating element that provides current draw to the oven safety valve.
- Behavior: heats to electron-emitting temperature, then maintains currentâ to allow gas flow.
- Common symptomsâ of failure: no glow, extended glow âtime,â or intermittent operation.

Common Failure Symptoms and Diagnostic Voltage/Resistance Criteria for Ignitor Assessment
The 5303935067 Frigidaireâ Range Flat Oven Ignitor 3-1/4″ is a hot-surface ignitor âdesigned to heat to aâ glowing state and draw sufficientâ current to allowâ the oven’s gas safety valve to open. In normal operation the element must reach⤠a prescribed temperature⢠quickly and present the electrical characteristics expected by the range control âand gas valve circuit; â¤a unit â¤that glows visibly but draws âtoo little current will â¤prevent valve⣠opening even though it appears to⣠operate.â This ignitor is mechanically and electrically compatible with specified Frigidaire range models that⢠accept the âflat 3-1/4″ form factor âand the same terminal configurationand âtechnicians should verify âmounting andâ lead polarity (where â¤applicable) when replacing to ensure proper fit and⣠reliable thermal coupling to the burner âassembly.
Technicians diagnose failure by⤠measuring âŁstatic resistance and applied voltage/current during a âcall for heat. Using a⢠multimeter across the ignitor terminals with power removed will show a low-ohm reading for a healthy element; a cold resistance significantly above the expected range or an open circuit indicates deterioration or break. When the controller requests bake, â˘a meter should⤠read approximately 120 VAC at the ignitor terminals; seeing line voltage with little or âno glow⢠points⣠to a bad ignitor, while no voltage indicates âa control, safetyor âwiring problem. âFor further verification⣠a clamp â¤ammeter can confirm the ignitor drawsâ the â˘model-specific operating current (typically a few amps on common oven ignitors); currents well below spec during â˘glow suggest the element has lost â˘emissivity and will not⣠reliably âlight the burner.
- Symptom: No âŁignitionâ or very long preheat time despite visible glow.
- Symptom: âIgnitor glows dimly orâ intermittently and oven fails to reach temperature.
- Symptom: Controller applies voltage but burner neverâ opens (voltage present with⤠no sufficient current).
| Item | Description |
|---|---|
| Cold resistance | Typical measured âŁrange for many oven ignitors is low ohms; âŁa much higher-than-expected reading or open circuit indicates a failed element. |
| Operational voltage | Approximately 120 VAC should be present at the ignitor during a⢠bake â˘call; voltage present with no glow = ignitor fault, no voltage = control/safety/wiring fault. |
| Typical current draw | Healthy ignitors draw a few amps âwhen at operating âtemperature;â values â˘below the model specification meanâ insufficient thermal output to open theâ gas valve. |
Replacement Considerations, Modelâ Compatibility and StepâbyâStep Installation Procedures
The 5303935067 Frigidaire Range Flat Oven Ignitor 3-1/4″⤠is a flat-style hot surface ignitor used to initiate gasâ flow in many Frigidaire ranges; it heatsâ to a high temperature and⤠then drawsâ sufficient current to signal the oven control or integrated gas valve that it is safe toâ open. Functionally this part must match the original â˘ignitor’s physical dimensions, mounting bracket geometry, lead length and terminal type so the control harness and mounting holes align without forcing⢠wiring or bracket deformation.Technicians should verify that the 3-1/4″ measurement corresponds to the âvisible element length and check connector style (spade vs. two-pin harness) and cold resistance against the OEM specification before installation to confirm⢠electrical compatibility. A cracked ceramic surface, âsignificant â¤change inâ cold⢠resistanceor incorrectly positioned element will alter ignition⤠timeâ or âprevent the gas valve âfrom opening âsafely.
Replacement and testing follow a clearâ procedural flow that protects theâ user and preserves component integrity: disconnect all power to the range and confirm zero voltage with a meter, âremoveâ oven â¤racks and access panels to expose the ignitor assembly, unfasten retaining screwsand disconnect theâ ignitor leads from the harness. when fitting the new 5303935067 ignitor, avoid touching the ceramic or glass surface with bare hands, secure⣠the bracket without overtightening, then restore power and perform a live test-observe the glow-up time and verify stable mainsâ voltage to the âignitor; if the element glows but the burner fails to light within the expected (typically short) interval, check wiring, terminal continuity and the gas valve/oven control. For clarity, common replacement steps are summarized below⤠and a short technical reference table providesâ speedy specs for field checks.
- Power off and confirm with a âmeter
- Remove oven racks and access panel to reach ignitor
- Unfasten screws and disconnect⤠wiring harness/terminals
- Compare old âand new ignitor for â¤length, bracketand terminal type
- Install new ignitor, reassemble, restore powerand perform ignition test
- If ignitionâ fails, measure ignitor resistance and supply voltage, then⤠inspect⤠control/gas valve

Q&A
What is the 5303935067⢠Frigidaire flat oven ignitor and what does it âŁdo?
The 5303935067 is aâ flat “glow âŁbar” ignitor used in many Frigidaire gas ranges. It heats to a high temperature when the â¤oven⣠calls for heat; once hotâ it allows â¤the gas safety valve toâ open and the gas⤠to ignite. It is an electricalâ component (not a spark ignitor) and is critical for reliable burner ignition.
What âare the common symptoms âof a failing oven ignitor?
Common signs include:â oven not lighting while broiler or bake control⣠clicks, long ignition delay before flame, a weak or intermittent⢠flame, â˘or⣠the ignitor not glowing âat all. You may also⢠see the ignitor glow âdimmer than normal or find visibleâ cracking/chipping of the ceramic coating.
How can Iâ test this ignitor with a multimeter and what readings are expected?
With power disconnected,check for continuity and measure cold resistance across the two ignitor leads. Many glow-bar ignitors show a cold resistance âŁroughlyâ in theâ range of â40-200 âŁohms â˘(manufacturers vary)and continuity should be present. However, continuity alone doesn’t guarantee proper function: a failing ignitor can have measurable resistance but not draw enough current when hot. Technicians often measure running current under load (the ignitor â˘typically â˘must â¤draw âaround 3-4 A⣠at 120 V to âopen the gas valve). If resistance is outside expected range or current draw is too low, replace the ignitor.
Does “3-1/4″” refer to the ignitor lengthand how do I know if it will fit my range?
Yes-3-1/4″ refers to the ignitor’s overall length/element size for this flat style. Fit depends on more than length: mounting hole spacing, terminal typeand wire harness/connectors must match. Alwaysâ check your appliance model number against the part cross-reference or theâ manufacturer’s parts list to confirm compatibility before ordering.
Can I⣠replace the 5303935067 ignitor myselfand whatâ safety precautions should⤠I take?
Many homeowners with basic mechanical skills can âreplace an âŁoven ignitor, but work involves âŁelectrical and⤠gas systems.⤠Safety precautions: disconnect electrical power to the range and, if applicable, turn off gas supply before â˘starting.â Avoid forcing or exposing wiring insulation.If you âŁare not pleasant or if localâ codes require⣠it, hireâ a qualified technician. If you attempt replacement yourself, â¤keep instructions high-levelâ (remove⣠oven âfloor or access panel to â˘reach the ignitor mounting, disconnect â˘leads, swap the partand reassemble)⤠and do final leak checks and functionalâ tests after reassembly.
how long do âthese ignitors last and what causes them to⤠fail?
Typical service life is commonly 5-10⣠years butâ varies â¤with usage. Failure causes include thermal cycling (repeated heating/cooling), age-related degradation â˘of the ceramic coating,⤠vibration damage,â and electrical stress. Contamination or physical damage to the element also shortens life.
Should I buy an OEM 5303935067 or an aftermarket replacement?
OEM parts provide âguaranteed fit, mountingand terminal match for the intended models â¤and often come with manufacturer support. â¤Reputable aftermarket ignitorsâ can beâ less⢠expensive and work fine, but quality varies-verify return policy, warrantyand compatibility. For reliable operation and correct fit,â OEM orâ quality aftermarket from a known⢠supplier is⤠recommended.
If the ignitor âŁlooks okay, what other components could prevent my oven from â¤lighting?
Other possible causes: a faulty gas safety/combination âvalveâ (won’t open even with⣠a good ignitor), failed electronic control board⤠or thermostat that doesn’t supply power to the ignitor, damaged wiring or connectorsor a clogged gas line/jet.Diagnosing those requires checking supply voltages, continuity â¤of⣠control â¤circuitsand⢠the gas valve operation-if you’re unsure, call a qualified service technician.
The Conclusion
The 5303935067 frigidaire Range Flat Oven Ignitor 3-1/4″ servesâ a critical âfunction in â¤gas oven operation byâ reliably initiating the â¤burner and ensuring consistent, efficient⢠heat for cooking.
