5303935067 Frigidaire Range Flat Oven Ignitor 3-1/4″ is a flat-style hot surface⤠ignitor (glow bar) used in many âFrigidaire gas ranges â¤and ovens.⣠Itâ is a replaceable heating element manufactured to a specific physical length and mounting â¤configuration, intended to â¤reach incandescent temperatures and provide the thermal and electrical characteristics required to initiate the oven’s gas ignition sequence. as a component, it typically consists of a ceramic-supported heating â¤element with terminal connectors â˘and mounting tabs designed to âŁfit the oven burnerâ assembly.
Functionally, the â¤ignitor âŁis part of the appliance’s gas ignition â¤system and interfaces directly with the oven’s gas safety⣠valve, control electronics, temperature control systemâ and wiring harness. During âa bakeâ or broil cycle the âignitorâ must heatâ upâ to its⢠operating temperature⢠and draw the correct current so the gas valve will open; if it fails to reach temperature or its electrical â¤characteristics change, the safety valve will remain closed and the burner will⣠not light. As it operates in â¤a high-temperature, cyclic â¤environment⤠and is electrically driven, the ignitor’s condition and installation affect both ignition reliability and safe operation of the gas delivery system.
In â¤the article that follows, readers will find a technical overview ofâ the 5303935067 ignitor’s â˘function and the âphysical and electrical attributesâ that determine compatibility⢠with âspecific range models, common failureâ symptoms to recognize (no heat, extended preheat, delayed ignition or weak flame), step-by-step âtroubleshooting procedures⤠(visual⢠inspection, continuity checks, current/voltage verification and interaction âtests with the gas⣠valve and control board)and practical replacement⣠considerations including safety â˘precautions, correct mounting and connector matching.⣠The â¤factsâ is presented to âassist technicians,⤠engineers and appliance owners in making informed diagnostic âŁand repair decisions while observing appropriate safety practices and verifying part specifications for their particular appliance.

Function and Operational â¤Role ofâ the Oven Ignitor in frigidaire Ranges
The 5303935067 Frigidaire Range⢠Flat Oven Ignitor 3-1/4″ is a flat-profile glow-bar ignitor designed to replace the original ignitor assembly in âcompatible âFrigidaire ranges. As a direct replacement part, its 3-1/4″ âceramic-and-nichrome-style element and mounting footprint are⢠intended to fit the oven floor or burner box whereâ a flat ignitor is specified; â¤installers should confirm connector type and screw locations against the existing unit before ordering. The component’s â¤primary mechanical considerationsâ are â¤its flat shape for clearance in the burner cavity and the specific lead/connector arrangement that ensures proper electrical and physical fit within the range’s ignitor âŁbracket.
The ignitor functions asâ a resistive glow element â that, when supplied âwith âline voltage, heats to incandescence and draws enoughâ current through the circuitâ to permit the gasâ safety valve to open and release gas for ignition. Inâ normal⣠operation the ignitor⢠will reachâ its operating âŁtemperature within a predictable warm-up interval and produce a steady, even orange glow; degradation manifestsâ as slower heat-up, âŁdim or uneven glowor open-circuit failure, any of â˘wich prevents the valve from actuating and the burner⤠fromâ lighting. Technicians typically⣠verify functionality by visual âinspection, âŁcontinuity checksand observing current draw during start-up; practical âservice replacement of the ignitor commonly restores normal âignition timing and oven heat if the element has become glazed, crackedor drawn down⣠in output.
- Flat design:⣠intended for low-profile mounting in compatible⣠Frigidaire ovens.
- Operational behavior: warms to a steady incandescent glow, drawing current required to enable the gas valve.
- Common⤠failure signs: extended preheat, no glow, oven will not lightor intermittent ignition.
- Installation notes: â˘match connector type and mountingâ holes; â˘disconnect power and gas â¤before service.

How the 5303935067⢠Frigidaire Range Flat Oven Ignitor 3-1/4″ Integrates with the Range’s control, Ignition, â˘and Safety Systems
The 5303935067 Frigidaire Range âFlat Oven Ignitor 3-1/4″ is a⣠glow-bar style ignitorâ that âintegrates directly âwith âthe range’sâ control, ignitionand⢠safety circuits byâ presenting a predictable electrical load⤠and heat⢠source at the burner port. âŁWhen the control board calls for⢠bake or broil, it â¤supplies voltageâ to the ignitor circuit; the ignitor⤠must heat to its operating temperature âŁand change its electricalâ characteristics so that sufficient â˘current flows to the gas safety â˘valve solenoid, allowing âthe âvalve to open and gas to⤠flow.The control electronics monitor the current/voltage behaviorâ andâ timing of the ignitor circuit to confirm a valid ignition sequence; if the ignitor fails to reach the required condition within the âcontrol’s timeout⣠window, the board will interrupt the gas supply to prevent unlit gas⢠accumulation. Some Frigidaire ranges â¤include separate flame-sensing inputs,â whileâ others rely on the control’s measurement of the âŁignitor circuit, so âcorrect electrical matching âand placement of⣠the ignitor are essential for proper interaction with the âŁsafety logic.
Compatibility and practical âservicing considerations focus on matching the ignitor’s⢠physical⢠and electrical characteristicsâ toâ the oven. The replacement ignitor must âphysically align beneathâ the burner port (the 3-1/4″ specification affects bracket fit and distance to the burner), use the same connector type,⤠and present the same cold-resistance/current draw so the control and gas⢠valve operate predictably. Technicians verify condition with a multimeter for continuity and relative resistanceand with an in-circuit current measurement to confirm the ignitor drawsâ the expected⣠operating current when powered; â¤an ignitor⣠that⣠glows slowly or shows âŁelevated resistance typically causes delayed ignition, longer gas valve âopen attemptsor control timeouts. Always de-energize electrical power and isolate the⢠gas supply âbefore âtesting or replacing⤠the ignitor to avoid electric⤠shock and gas leaks.

common Failure Modes â˘and⢠Diagnostic Symptoms of a Degraded or Failed Oven Ignitor
The⢠5303935067 Frigidaire Range Flat Oven Ignitor 3-1/4″ is a âŁflatâ hot-surface ignitor whose role is toâ heat to aâ radiant orange glow and draw sufficient current âto allow the oven’s gas safety valve to open. Typical failure modes are filament breakage, progressive coating⤠degradation that reduces emissivity, internal âcracks â˘from thermal cyclingandâ poor electrical connections at the terminal â˘block. A degraded ignitor will often still glow but⣠at a lower intensityâ and for a longer period before the⣠valve trips, producing⤠symptoms â¤such as long preheat times, intermittent lightingor complete â¤loss of oven heat even though the control and gas supply appear functional; in many diagnostic cases the ignitor itself âŁis the limiting element in the âŁignition circuit rather than âthe valveâ or control board.
- Dim or slow-to-glow⣠element with âdelayed ignition
- Oven that will not reach âŁset temperature or cyclesâ frequently
- Repeated ignition attempts or clicking noises withâ no flame
- Visible physical damage, cracksor broken⣠terminals on the ignitor
For â˘practicalâ diagnostics use a combinationâ of visual checks and electrical measurements: perform â˘a visual inspection for cracks, contaminantsor loose wiring; check âŁcontinuity and compare resistance to manufacturer specifications or a known-good âunit; and measure the current draw under live conditions as a failing â¤ignitor⤠can âŁshow acceptable resistance but still fail to draw the amperageâ required to actuate â˘the gas valve. Observe the glow-up time – a healthy ignitor typically reachesâ a bright orange glow within about 30-60 seconds – and verify that âthe â˘valveâ receives proper âvoltage when the ignitor is âat operating temperature.â If measurements âindicate low emissivity âor insufficient current, replacement of the ignitor is the correct remedy; â¤always isolate power and gas before performing replacements or insulation-resistance â¤tests.
| Item | Description |
|---|---|
| Measured⤠resistance | Open or very⣠high resistance indicates a broken â˘element; compare to spec or⤠a known-good unit. |
| Glow behavior | Dim âorâ slow glow suggests reduced emissivity from⤠age or coating damage and usually correlates with poor current draw. |
| Current⣠draw | Insufficient amperage⢠under live load prevents theâ gas valve from opening even⣠if the ignitor glowsâ faintly. |
Compatibility,Replacement considerations and Step-by-Step Installation⣠Procedures forâ Frigidaire Models
The âŁ5303935067 Frigidaire Range Flat Oven Ignitor 3-1/4″ is a line-voltage hot surface ignitor designed to replace flat-style ignitors on compatible Frigidaire gas âranges. Functionally it converts electrical energy to heat untill the â¤tip reaches a temperature sufficient to openâ the â¤oven safety gas valveâ and⤠ignite the burner; âŁduringâ normal âoperation the component should glow⢠visibly and present continuity at the terminals. â¤Compatibility depends on physical mounting⣠(flat pad vs. rod), overall length, terminal style (spade or screw),â and thermal/voltage rating – substitute parts must match these âmechanical and electrical characteristics to âensure proper valve current draw and safe ignition behavior.A⢠common â¤symptom⤠of a failed ignitor is complete loss â¤of â¤ignition or extended preheat time despite correct âŁgas supply; technicians verify failure with a continuity check and⢠by observing absence of glow when energized underâ controlledâ test conditions.
Replacement ârequires â˘simple mechanical and electrical steps but âstrict âŁadherence⤠to âsafety and verification procedures to avoid gas leaks or âelectrical faults. After installing a correct 5303935067 replacement, verify secure mounting, correctâ orientation toward the burner, tight âelectrical connectionsand that the ignitor does âŁnot contact sheet metal; final checks include energizing the oven⤠to confirm the ignitor glows, observing stable, even burner ignition,⣠and âperforming a leak check at the gas âŁconnection. Practical examples: using aâ multimeter to confirm continuity before and after replacement prevents unneeded gas shutoff eventsand swapping a flat ignitor for a rod-style ignitor without adapter plates⣠or correct current characteristics will typically â¤result in poor ignition⤠or failure to open the⤠safety valve.
- Disconnect power and gas before accessing the ignitor.
- Remove oven access panel or oven bottom to expose the ignitor assembly.
- Note wiring and mounting orientation, â¤then disconnect terminals and remove mounting screws.
- Install the â¤new 3-1/4″ flat ignitor with identical orientation, secure fastenersand reconnect wiring.
- Restoreâ power and gas, observe ignitor glow and ignition sequence, then check⤠for proper flame pattern and gas leaks.

Q&A
What is the 5303935067 Frigidaire⤠Range Flat⤠Ovenâ Ignitor 3-1/4″ âand what does the “3-1/4″” meen?
the 5303935067 is a hot-surface⢠(flat) oven ignitorâ used on many Frigidaire ranges. The “3-1/4″”⢠refers to â˘the length of the â˘ceramic/glass heating surface or the exposed element portion of the ignitor – a⤠physical â¤dimension used to âŁmatch the replacement to âthe original part so it⢠mounts and positions correctly in the burner assembly.
How⣠do I know âthe 5303935067 ignitor⤠is the â˘correct replacement for my oven?
Confirm compatibility by matching the part number to your⢠range’s parts list⢠or service manual and by â˘comparing the physical shape, mounting holes and connector to your old ignitor. If you don’t have documentation, remove the old ignitor and âŁcompare length, mounting bracket location and electrical âŁconnector. When inâ doubt, check with the appliance manufacturer or a âverified parts supplier using your oven model number.
What âŁare common signs that this oven ignitor has failed âor is failing?
Common symptoms include: the âoven won’t light or takes âa very long time to light, preheat times are âmuch⢠longer than normal, the⤠bake burner never establishes a steady flameor the ignitor glows very weakly or âŁnot at all.A weak ignitor can glow âbut ânot drawâ enough current to open the gas safety valve, so the burner will ânot ignite.
Can Iâ test the âŁ5303935067 â˘ignitor myself âand how?
Yes – with safety precautions. First disconnect power and turn off the âŁgas. Use a multimeter â˘to⤠check for continuity/resistance across â¤the⢠ignitor leads; an open circuit indicates a failed ignitor.
