5303935067 Frigidaire Range flat Oven Ignitor 3-1/4″ is a flat-style hot surface ignitor used in gas ranges; it is a ceramic-based heating element that converts electrical energy into heat to initiate burner ignition. As a direct-replacement part specified by size and connector type, this ignitor is designed to fit the oven burner assembly and mount to the oven floor or burner housing, and its 3-1/4″ dimension is a key physical specification for fit and clearance in the appliance cavity.
Inside the appliance the ignitor functions as the primary ignition source and a permissive signal for the gas safety valve: when energized it heats to a red-glow temperature and draws sufficient current to allow the gas valve to open and deliver fuel to the burner. The ignitor therefore interfaces electrically with the range control board or thermostat, mechanically with the burner assembly and mounting bracket, and indirectly with the gas valve and flame sensor; its condition affects ignition timing, gas flow safety interlocks, and combustion reliability.
In this article you will find a technical overview of the ignitor’s function and construction, guidance on compatibility and fit (including why the 3-1/4″ form factor matters), common failure symptoms to watch for (no glow, long preheat, repeated clicking, or inability to light), practical troubleshooting checks that are useful to technicians (visual inspection, continuity and resistance checks, and verification of applied voltage and current), and replacement considerations such as matching part number, connector type, mounting orientation, and basic safety precautions when servicing a gas appliance.

Function and Operational Role of the Flat Oven Ignitor in Gas Ranges
The 5303935067 Frigidaire Range Flat Oven Ignitor 3-1/4″ is a flat glow-bar style ignitor that provides the thermal energy required to open the oven’s gas safety valve and start combustion. Electrically it converts line voltage into heat; when the element reaches its operating temperature it draws the designed current that allows the gas valve coil to energize and admit gas. The ignitor does not itself regulate gas flow – its role is mechanical/electrical: heat to a specified emissive level, sustain that level long enough for valve actuation, then repeat each ignition cycle. In practical service, observing whether the element glows evenly and checking the current draw under live conditions are the most reliable ways to assess function.
Compatibility for this flat oven ignitor is steadfast by physical dimensions, mounting arrangement, and connector type: the 3-1/4″ flat profile and two-wire terminals match many Frigidaire range models that originally used part number 5303935067. Replacement involves ensuring the ignitor’s length and mounting brackets align with the oven’s burner assembly and that wiring harness connectors are compatible. Technicians diagnose failures by visual inspection for cracks or blisters, continuity checks to confirm the filament is not open, and in-circuit current measurement to verify the ignitor draws the necessary current to actuate the gas valve; a unit that glows faintly or fails to reach full emissive temperature typically requires replacement to restore reliable ignition.
- common symptoms: delayed ignition, oven cycles without sustaining flame, or no heat despite power to the range.
- Swift checks: visual glow inspection, continuity test with a multimeter, and live current measurement across the ignitor during a start cycle.
- Installation notes: confirm mounting orientation and secure spade terminals; avoid bending the element or handling it with bare hands to prevent damage.

How the 5303935067 Frigidaire Range Flat oven Ignitor 3-1/4″ integrates into the Ignition Circuit and Generates Heat to Open the Gas Valve
The 5303935067 Frigidaire Range Flat Oven Ignitor 3-1/4″ functions as a hot-surface element placed in the oven’s ignition circuit so that, when line voltage is applied, the element converts electrical energy into heat. As a resistive heater it is installed in series with the oven’s safety gas valve or is monitored by the gas valve’s sensing circuit; when the ignitor reaches its operating temperature it conducts the required current or produces the voltage signal that allows the valve to open. In practice this means the ignitor must both reach a visible orange glow and present the expected cold- and hot-resistance behavior – technicians verify compatibility by matching the 3-1/4″ flat form factor, terminal type (typically two spade terminals), and the expected electrical characteristics for the specific Frigidaire range model it serves.
Thermally, the ignitor generates heat thru Joule heating of the ceramic/filament carrier until its surface emits sufficient thermal energy to ignite the gas once the valve opens; electrically, its changing resistance as it warms is integral to the control logic that permits valve operation. Common troubleshooting examples include an ignitor that glows slowly or not at all (indicating high resistance or partial failure), or an ignitor that glows but does not allow the gas valve to open (indicating insufficient current draw or wiring/sensing issues). for service, measure cold resistance and in-circuit current draw with appropriate meters, confirm secure spade connections and correct mounting, and replace with a matching 5303935067 unit when the element fails to meet the required thermal or electrical response.
- Function: hot-surface resistive element that heats and enables gas valve actuation.
- Common failure symptoms: no glow, slow glow, or glow without valve opening.
- Diagnostic checks: visual glow inspection, cold-resistance check, in-circuit current measurement.
- Compatibility notes: match length, flat profile, terminal type, and electrical behavior to original part.

Diagnostic Indicators and Common Failure Symptoms of a Degraded or Failed Flat Oven Ignitor
The 5303935067 Frigidaire Range Flat Oven Ignitor 3-1/4″ functions as a hot surface element that heats to a glowing temperature to allow the gas safety valve to open and sustain a stable burner flame. In normal operation the ignitor presents a low cold resistance and, when energized, draws the specified operating current long enough to heat to full glow; a degraded flat ignitor will glow dimly, take substantially longer to reach temperature, or fail to draw sufficient current, preventing the gas valve from opening. Technicians should recognize that this flat-type ignitor is mechanically and electrically different from tubular or J-shaped ignitors and must match mounting footprint and lead configuration for correct replacement; an ignitor that fits physically but has lower-then-required current draw will still cause ignition failures even if it appears to mount correctly.
- Oven will not light or requires repeated attempts to ignite despite gas supply being present.
- Ignitor glows weakly or unevenly, or takes significantly longer than the original component to reach full brightness.
- Gas valve clicking or humming without sustained flame – sign the valve is trying to open but current from the ignitor is insufficient.
- Extended bake times, inconsistent temperature, or broil not reaching set temperatures.
- Visible cracking, blistering, or flaking of the ceramic/glass surface on the ignitor element.
| Item | Description |
|---|---|
| Typical cold resistance | Often in the low tens to low hundreds of ohms (varies by design); an open circuit indicates failure. |
| Operating current | Degraded ignitors draw noticeably less current when powered; verify with a clamp meter against manufacturer spec. |
| Visual/functional test | Dim glow, slow heat-up or inability to light the burner are practical indicators that the element is failing. |
Diagnostic verification combines visual inspection with electrical testing: measure cold resistance with a multimeter (open or very high resistance indicates a failed element) and confirm operating current with a clamp meter while the oven attempts ignition; measure values against the range manufacturer’s service data when available. For example, an ignitor that glows but does not allow ignition often still draws some current but falls below the threshold needed to actuate the gas valve - replacing with a correctly rated 5303935067 Frigidaire Range Flat Oven Ignitor 3-1/4″ or equivalent typically restores proper current draw and reliable ignition. Always isolate power and gas before performing tests or replacement, and document measured resistance/current and observed glow behavior to support warranty or parts selection decisions.
Compatibility, Replacement Considerations, Installation Procedure, and Post-Installation Diagnostics
The 5303935067 Frigidaire Range Flat Oven Ignitor 3-1/4″ functions as a resistive hot-surface ignitor that draws current and generates heat sufficient to actuate the oven’s gas valve during the ignition sequence. Compatibility is governed by mechanical length, mounting flange orientation, and electrical characteristics; the nominal 3-1/4″ length must match the original part so the tip sits correctly in the burner tube and the mounting holes align with the bracket. Replacement considerations include matching connector type (typically push-on spade), verifying that the oven control supplies the correct voltage, and confirming that the gas valve and safety interlocks are operational – an otherwise good ignitor will not light gas if the valve or wiring is faulty. Handle the ceramic and element tip carefully to avoid oil contamination, and ensure the replacement part’s electrical characteristics are within the appliance manufacturer’s specification before installation.
Install the ignitor with the appliance power and gas supply off, using the OEM mounting orientation and torque values for screws to prevent stress on the brittle element. After reassembly and restoring power and gas, perform post-installation diagnostics: observe the ignitor for a steady, luminous orange glow within a few seconds of the control calling for heat, confirm the gas valve opens when the ignitor current reaches the valve’s rating, and measure the ignitor cold resistance and operating current with a multimeter/ammeter to compare against expected values. If the ignitor glows weakly or cycles repeatedly without lighting the gas, record resistance and current readings and inspect wiring, harness continuity, and the gas valve coil; a dim glow often indicates degraded emissivity or internal cracks that reduce current draw and prevent valve actuation.
- Pre-install: disconnect power and gas, confirm part number and connector type.
- Installation: secure ignitor to bracket without bending element, reconnect harness, and seal access panels.
- Post-install test: verify steady orange glow, confirm gas valve opens, measure cold resistance and operating current.
- Troubleshoot: if ignition fails, check continuity to control and gas valve coil, and replace valve if current is within spec but valve remains closed.

Q&A
What models is the 5303935067 Frigidaire flat oven ignitor (3-1/4″) compatible with?
The 5303935067 is a common flat (plate-style) hot surface ignitor used on many Frigidaire/frigidaire Gallery/Frigidaire Professional and some Electrolux and Kenmore gas ranges.Compatibility depends on physical dimensions, mounting hole spacing, connector type and electrical rating (typically 120 VAC). Always check your range’s model number against the part cross‑reference or the oven’s parts diagram before ordering. If the shape,mounting pattern and two‑wire connector match,it is likely compatible.
What are the typical symptoms that indicate the oven ignitor needs replacement?
Common signs of a failing ignitor include: oven takes a long time to light (longer than ~60-90 seconds), oven won’t reach the set temperature, the ignitor glows dimly or not at all, clicking noise without ignition, or the gas valve never opens because the ignitor cannot draw enough current. Visual inspection showing cracks or a dark film on the ignitor also indicates replacement is needed.
How can I test this ignitor to confirm it’s bad?
there are two practical tests: 1) visual/functional: if the ignitor does not glow bright orange when the oven calls for heat, it is indeed likely bad.2) Electrical test: measure current draw while the oven is calling for heat – a working flat hot surface ignitor typically draws around 2.5-3.5 amps at 120 VAC; a low current (significantly below that) means it won’t open the gas valve. you can also measure cold resistance with a multimeter (expect a low resistance in the tens of ohms for many ignitors), but resistance alone is not definitive as the ignitor’s heating characteristic is what matters.
Is this a 120V part and can I use a universal ignitor instead?
Most Frigidaire oven ignitors, including this flat‑style part, are 120 VAC. You can use a universal replacement only if it matches the original’s electrical rating, connector type, mounting configuration and physical dimensions. Using an ignitor with different voltage/current characteristics can prevent proper gas valve operation or create a safety hazard, so match specifications exactly or use a manufacturer/recommended OEM cross‑reference.
Can I install the 5303935067 ignitor myself? what are the basic steps?
experienced DIYers can replace an ignitor, but observe safety precautions: turn off electrical power to the range and shut off the gas supply. Typical steps: remove the oven door or bottom panel for access, disconnect the ignitor wiring harness, remove mounting screws and the old ignitor, install the new ignitor in the same orientation, secure screws, reconnect wiring, restore power and gas, and test for proper glow and ignition. Avoid touching the ceramic or heating surface with bare hands. If unsure, hire a qualified appliance technician.
Do I need any special tools or parts when replacing this ignitor?
Basic tools are usually sufficient: screwdriver (Philips or Torx depending on screws), nut driver or socket set, multimeter or clamp meter for testing, and possibly needle‑nose pliers. Replacement mounting screws or a new wire harness clip may be needed if the originals are corroded or damaged. Have the oven model and part number on hand to confirm fitment.
how long does an oven ignitor typically last and is it worth replacing versus buying a new range?
Hot surface ignitors commonly last several years; averages range from 3 to 10+ years depending on use and manufacturer. Replacing the ignitor is usually inexpensive and simple compared to replacing the entire range, so if the oven is or else in good condition the repair is cost‑effective. Consider range age, other failing components, and cost of repair vs. replacement when deciding.
Are there any installation warnings or safety tips specific to flat oven ignitors?
yes. Always disconnect mains power and turn off gas before working. Do not force or bend the ceramic/heating surface, and avoid touching the ceramic with bare skin (oils can damage it). Ensure the replacement ignitor is positioned identically to the old one so the flame pattern is correct. If the ignitor fails to draw sufficient current after installation, do not repeatedly attempt to light the oven – this could allow gas to accumulate. Call a qualified technician if you’re uncertain or detect gas odors.
