5303935067 Frigidaire Range âŁFlat Oven Ignitor 3-1/4″ is a flat-style hot surface ignitor designed⢠forâ gas ovens andâ ranges; it is⢠a replaceable ignition elementâ that heats to a high temperature to initiate combustion of the burner gas. The⢠component⢠typically consists of a ceramic or silicon carbide⤠glow âŁelement⣠bonded to a mounting plate withâ electrical terminals âŁand a⣠specified overall length of âŁ3-1/4″,â making its physical dimensions and terminal types critically⤠important forâ correct fit and electrical connection.⢠As a discrete replaceable part, it is indeed specified by appliance model compatibility and by⢠electrical and thermalâ characteristics⤠rather âthan⢠by aesthetic features.
inside â¤the â˘appliance the⢠ignitor serves â˘as the primary⤠ignition source and a functional âinterlock⤠in the⤠gasâ ignition âsequence: when energized by theâ oven control, the ignitor draws⤠current and glows until⣠it reaches âsufficient temperature to cause â˘gas released by the gas valve â˘to ignite. â¤It interacts âdirectly with the oven control board⢠(or â¤electromechanical âthermostat) for timing,⣠the⣠gas valve which⢠is actuated only after the ignitor reachesâ the required⢠temperature âor â¤current drawand the wiring âŁharness and mounting assembly that âprovide electrical and mechanical⢠interfaces.â Because proper operation âŁdepends on both thermal response and electrical parameters, the ignitor’s resistance, current draw,â andâ warm-up âprofile influence valve actuation timing, â˘ignition reliabilityand preheat performance.
This article â˘explains the technical function âof the 5303935067 â¤ignitor, outlines model andâ connector compatibility considerationsand describes common failure âŁsymptoms⣠such as âextendedâ preheat â˘times, no ignitionor intermittentâ glow.â It also âcovers diagnostic checks useful⢠to technicians and⣠informed owners-visual inspection, resistance and amp-draw âŁmeasurementsand observing warm-up behavior-and discusses practical replacement considerations including matching physical dimensions, terminal types, âmounting orientationand safety â˘precautions âto take âbefore⤠servicing the âgas and âelectrical systems. The âgoal is to provideâ clear technical context for evaluating, troubleshootingand âreplacing this specific âŁignitor in âFrigidaire gas rangesâ and âsimilar appliances.

Functionâ and Electrical Role ofâ the Oven Ignitor⢠in Gas Range âŁHeating and Safety âCircuits
The 5303935067⣠Frigidaire Range Flat Oven Ignitor 3-1/4″ â¤is a hotâsurface⣠ignition element that serves two electrical roles in a gas range:⢠it provides the heat source that ignitesâ the burner â¤and it functions as part of the oven’s safety/interlock circuit. âElectrically, the ignitor is âŁa resistive element âthat draws a defined⢠current â¤when â¤cold; the oven⤠control⢠or gas valve senses thisâ current draw âand will â˘only open the valve when the ignitor has reachedâ sufficientâ temperatureâ and âcurrent level. A degraded ignitor can stillâ glow visibly â¤yet fail to âdraw the necessary current, preventing the valve from opening âand resulting in no ignition â˘despite apparent âheating.Proper âŁreplacement requires matching the element’s length,â mounting, â˘terminal type, â¤and electrical characteristics so the control logic âand valve âtiming remain within design tolerances.
- Slow orâ no gas flow despite â˘a⣠glowing ignitor
- Long ignition delay before burner lights
- Intermittent operation or oven⤠cycling off shortly after ignition
- Open or veryâ highâ resistance âwhen measured âwith an ohmmeter
Technicians commonly diagnose a failingâ ignitorâ by measuring continuity and comparingâ cold resistanceâ or by âobserving current draw âduring⢠a start cycle; a clamp meter on the circuit during startup will show the higher⢠inrushâ current characteristic of⢠a healthy hot surface â˘ignitor. When replacing the part, verify the â¤spade terminalâ orientation, mounting⢠bracket alignmentand clearance from â˘nearby components to avoid âmechanical⣠stress or heat⢠transfer issues. For safety, â˘disconnect âŁelectrical powerâ and âthe gas supply before performing tests⤠or⤠replacement.The table below summarizes rapid⤠reference attributes⣠useful for matching and verifying the correct â˘ignitor during service.

Howâ the â5303935067 Frigidaire Range Flatâ Oven Ignitor â¤3-1/4″ âŁOperates â˘Within the â¤Range’s Ignition and Gas Control System
5303935067 âŁFrigidaire âŁRange Flat Oven â˘Ignitor 3-1/4″ is a â˘flat hot-surface âŁignitorâ designed to replace âthe original⣠flat-style element in âŁcompatible â¤Frigidaire gas ovens. â˘It operates âas a resistive heating⣠element:â when âŁtheâ oven âcontrol supplies voltage, the ignitor â¤heats until its surface glows and its electrical characteristics⣠change enough to allow the gas valve â˘solenoids to open.Proper compatibility requires matching âŁthe 3-1/4″ length, connector styleand mounting orientation so the element seats correctly against the burnerâ assembly; technicians typically confirm âfit visually and â¤check âfor an even,â shiningâ orange glow as evidence â˘of⣠adequate thermal output and currentâ draw.A cracked ceramic, corrosion âat the connectoror â˘visibly uneven âŁglow are âpractical â¤signsâ the ignitor âis no longer reaching required temperature or drawing sufficient current, causing delayedâ ignition or â¤failure to âlight.
- Role:â heat source⤠that enables gasâ valve operation by reaching required temperature âand currentâ draw
- Compatibility:⤠must âmatch length, connectorand mounting to ensure⢠correct thermal coupling
- Common symptoms of failure:⤠no glow, slow glow-up, intermittentâ glowor physical damage
- Field checks: visual glow test, continuity/resistance check,⣠and verification⢠of control-board voltage
In the⢠ignition andâ gas control sequence the oven âcontrol energizes âthe ignitor until it reaches âŁaâ thermal state âthat allows the safety gas valve âto âŁopen; the ignitor does not light⢠the gas âŁdirectly but creates the thermal and electrical conditionsâ neededâ for the valve to â¤operate reliably.â control modules either âŁmonitor current⤠draw or use timed âŁsequences to decide when âto âopen the valve, so an âignitor with â¤reduced heatingâ capability can produce the â˘same symptoms as âa âfailing control or valve. For service, â¤technicians compare observed behaviorâ against system⢠diagnostics-confirming â˘thatâ the control sends voltage, the â¤ignitor âglows uniformlyand âthe gas valve actuates-before replacing⤠parts; swapping in the correct 5303935067 part â˘restores âtheâ designed thermal⢠response and current characteristics â˘requiredâ by the range’s ignition system.

Common⣠Failure Symptoms andâ Diagnosticâ Measurements for a Faultyâ Oven Ignitor
The 5303935067 Frigidaire Range Flat Oven⤠Ignitor 3-1/4″â is a replacement â¤hot-surface ignitor used⣠on compatibleâ Frigidaireâ ranges; âit must⤠match the â¤physical length, mounting styleand âconnector âtype to⣠deliver the designed electrical characteristics.⤠The ignitor’sâ function is to heat â˘to a high temperature â˘so that it⣠draws sufficient current and allows the gas safety valve âŁto open; when âthe âignitor⣠ages or cracks,it either fails to glowâ or glows weakly,reducing âcurrent draw and preventing valve actuation.⤠Technicians should consider mechanical fit andâ measured electrical âbehavior together -â a⣠correctly sized flatâ ignitor that installs poorly orâ has different âresistance can⤠mimic a bad gasâ valve or control board, so isolating the ignitor with direct measurements âisâ the practical âway to confirm⢠the âfault.
- No âŁignition or oven remains cold despite control signals to spark or open the valve.
- Extended glow time before âgas âflow (long preheat)â or â¤slow recovery between cycles.
- Weak, âdimor⣠uneven⣠orange glow instead of a⣠bright, uniform glow.
- Intermittent heating where âthe oven cyclesâ but fails⣠to âsustain a flame.
- Open-circuitâ or visible crackingâ of the ceramic/filament.
Diagnosing⤠a suspect âignitor âŁbegins âwith⤠a â˘power-off resistance check and progressesâ to a live âŁcurrent measurement if safe toâ do so: use a multimeterâ to â¤check for continuityâ and approximate cold â¤resistance,â then âŁmeasure operating current with a clamp âmeter â¤or series âammeter whileâ the âoven is âcalling for heat. Aâ complete open circuit⤠indicates aâ failed filament; a resistance âŁvalue within â¤theâ expected range but with low âŁhot current typically indicates a âweakened â¤element that â¤will not âpull⣠the âgas valve. Also verify that the ignitorâ receivesâ the âcorrect line voltage and that connectors and mounting â˘allow full thermal contact with the â˘oven’s bracket – a misaligned 3-1/4″ flat â˘ignitorâ mayâ not âreach âthe intended temperatureâ even âifâ its cold resistance reads nominal.
| Item | Description |
|---|---|
| Cold resistance (approx.) | Typical ranges vary byâ design; approximate âŁvalues frequently enough fall in the tens of ohms (example: ~45-90 Ί).⣠An â¤open â˘circuit âindicates a failed element. |
| Operating current (hot) | When at operating temperature theâ ignitor must draw sufficient current âto open âthe âgas âŁvalve; typical hot currentâ is roughly 2-4 A depending on â˘model â˘and⢠supply voltage.Lower⣠hot current suggests a weakened ignitor. |
| Glow time | Ignitorâ should⢠reach bright⤠orange within seconds to a minute underâ load; significantly extended glow time indicatesâ degradation. |
Compatibility, Replacement Considerations â˘and Step-by-Step Installation Best Practices for the 5303935067 Ignitor
The â¤5303935067 Frigidaire⤠Range Flat Oven Ignitorâ 3-1/4″ is a flat-style hot surface ignitor that âreplaces the original⢠glow âelement âŁin âcompatible Frigidaire ranges. Functionally, the ignitor must reach incandescent temperature to allow the gas valve toâ open â¤and produce a stable âburner flame; compatibility depends â˘on matching â˘the physical length, mounting flange orientation,â connector⢠typeand electrical characteristics to the factory unit. Techniciansâ should verify âŁthe replacement⣠by comparing the âreplacement’s mounting tab spacing âand connector pin arrangement âŁto the removed ignitor,and âby confirming the appliance model’s parts â¤list or⢠service manual when⤠available. The âflat profile can affect⢠clearance in⤠the oven⤠cavity, so physical fit is⤠as âcritical as electrical⣠match for⢠reliable âoperation.
- Safety first: disconnect electrical power⣠and â˘shut off the⤠gas⢠supply before starting âŁthe replacement.
- Remove oven panels âto access theâ ignitor; âŁdocument screw âlocations âand wiring orientation before disconnecting theâ old unit.
- Measure âcontinuity of the old⤠ignitor and compare to⤠the new â¤unit or â¤manufacturer specification⣠to âconfirm electrical compatibility.
- Install the new unit with identical orientation⤠and secureâ mounting to â˘avoid âstress âon the â˘ceramic and glass surfaces.
- Reconnect wiring with proper high-temperature connectors and verify there⣠is no â˘chafing or pinching of the⢠harness.
- After reassembly, restore power and gas and âobserve multiple ignition cycles for âconsistent â¤glow time âandâ flame establishment.
| Item | Description |
|---|---|
| Length | 3-1/4″â nominal; verify âoverall and tip-to-flange dimensions against the âremoved âŁignitor |
| Mounting | Flat flange style – confirm screw hole pattern and clearance⣠inside burner âbox |
| Electrical check | Confirm âcontinuity and similar cold resistance â¤to âoriginal or service specification; large deviation suggests mismatch or defect |
After installation, validate⤠performance by timing âthe period from element glow toâ gas valve actuation and inspecting the⢠flame shape and stability; a delayed⣠or weak âflame indicates either insufficient ignitor current, incorrect partor gas valve issues. âIf the new â˘ignitor glowsâ but the valve does not open, test the gas âvalve circuit and control board â˘outputs⤠rather than assuming ignitor failure;⤠practical â˘troubleshooting isolates mechanical fit,⤠electrical continuity,â and the downstream control components to ensure âthe replacement resolves the⢠original symptom without introducing new faults.
Q&A
What is the 5303935067 Frigidaire Range Flat Oven Ignitor 3-1/4″ â¤used for?
this is a âhot-surface replacement ignitorâ forâ compatible Frigidaire/Frigidaire Galleryâ and âsome âElectrolux ranges. The ignitor glows whenâ the⣠oven calls for heatâ and, âŁonce it reaches the required temperature, allows the gas valveâ to open so the â˘burnerâ lights. âŁThe 3-1/4″ measurement refers to âthe length/size of the⣠flatâ ceramic/glow element and the âŁpart is designed to replace a failingâ OEM ignitor with the same â˘mounting/plug style.
how do I â¤know if the â5303935067 âignitor â˘isâ compatible with âmy oven?
Check your oven’s âŁmodel number and theâ original part number in the âowner’s⤠manual or parts âdiagram. Compatibility can also â˘be confirmed by âmatching the physical shape,mounting âŁhole locations and⣠connector â¤type (usually two spade âŁterminals). If available, look â˘up the part number â˘(5303935067) on the manufacturer parts lookup âor aâ trusted parts retailer toâ see⢠a list of compatible models. If unsure, provideâ yourâ oven model âto â˘a parts dealer or technician for⤠verification.
What are⤠the common symptoms of a âŁfailing flat oven ignitor?
Common signs âinclude: the oven not heating âatâ all,⤠very long preheat times, the ignitor not glowing or glowing dimly, the⤠bake/broil burners failing to light while theâ surfaceâ burners still work,â or repeated⤠clicking/attempts to light. A failed ignitor may âstill glow but not drawâ enough current to open⣠the gas valve -â so â¤visibleâ glow aloneâ does not guaranteeâ correct operation.
How can I test the 5303935067 ignitor to â¤determine if âit needs⤠replacement?
Safety first: âdisconnect power âand, âif⤠applicable, âturn⣠off the gas supply âŁbefore testing.â With a âmultimeter, check for continuity across the two ignitor terminals⣠-⣠an open circuit indicates a failed element.For â˘a more accurate assessment, compare âthe cold⤠resistance to theâ manufacturer’s specification in the service manual; if the resistance âis far outside the specified range or infinite, replace âit. âObserving operation (with âpower on and gas off by âŁa⣠qualified person) âŁ- the element should âŁglow bright orange quickly; a weak/dim glow can âŁindicate it is failing⢠even if it⤠still shows continuity.
What tools âŁand âsafety precautions are required to replace this ignitor?
Typical tools: screwdriver or âŁnut driver to remove the âoven â˘access panel â˘and mounting screws, needle-nose â¤pliersâ for â˘disconnecting spade terminalsand a multimeter for testing. Safety precautions: disconnect electrical âpower to the range at the breaker, shut⢠off the⢠gasâ supply if you âwill be disconnecting âgas âfittings â(though replacing the ignitor usually⤠does⤠not require â˘opening the gas⢠line),⤠avoidâ touchingâ the ceramic/glow âsurface with bare hands (oils can damage âit)and follow the⤠oven âmanufacturer’s instructions.⣠if you are⣠not pleasant⢠working with âgas orâ electrical components, hire a qualified appliance â˘technician.
Canâ I install the 5303935067 myselfand how long⤠does replacement typically take?
Manny experienced DIYers can replace a⤠plug-in ignitor âin 20-60 minutes.⣠The job â¤usually involves removing the oven â¤door or access panel, unplugging âthe â˘old ignitor’s â¤spade connectors, unscrewing â˘the mounting â˘bracketand installing theâ new ignitor in âŁthe same orientation.â Because the part and connections must⤠be correct and gas/electrical safety⣠is âinvolved,consider professional service if you⤠are⤠unsure or âŁfind unexpected wiring/mounting differences.
How longâ should a âreplacement⢠5303935067 ignitorâ last,and are thereâ any maintenance tips to prolong its life?
Hot-surface â¤ignitors⢠typically last⤠several years (commonly 5-10 years) but lifespan varies with use and operating conditions. To prolong life:â avoid touching âthe ceramic/glow âsurface, keep the âoven and⢠burner area clean and free âŁof heavy grease buildup, âand âaddress ârepeated hard â¤light cycles or gas valve problems promptly (these can stress the ignitor). If you â˘see recurring premature failures, have âa technician âinspect the gas valve⣠and control⢠circuitry for faults thatâ could be â˘causing âexcessive wear.
