5303935067 frigidaire Range Flat Oven Ignitor 3-1/4″ is a replacement hot-surface ignitor (glow bar) specified for certain Frigidaire gas ranges; it is a flat, low-voltage heating element sized to fit specific oven burner assemblies and mount points. As a purpose-built ignition component,it combines a heat-resistant ceramic/glass body with internal resistive elements to produce the radiant heat required to initiate combustion at the main burner.
The component’s role within the appliance is to heat to a consistent high temperature so the gas control system will permit the main gas valve to open and sustain combustion. It interfaces electrically with the range wiring harness and gas control module and mechanically with the burner and mounting bracket, and it functions as part of the oven’s safety chain by ensuring gas is released only when ignition temperature is present. proper operation depends on secure mounting, intact insulation and reliable electrical connections because any degradation in heat output or continuity directly affects ignition timing and valve operation.
In this article readers will find a technical explanation of the ignitor’s operating principles, guidance on compatibility and correct physical and electrical fit (including the implications of the 3-1/4″ flat form factor), typical failure symptoms to recognize (such as weak glow, delayed ignition or no heat), pragmatic troubleshooting checks (visual inspection, continuity and circuit-level diagnostics) and practical replacement considerations including connector type, mounting orientation and safety precautions for working around gas and electrical systems. The intent is to provide technicians, engineers and informed appliance owners with the details needed to diagnose ignition-related issues and select and install the appropriate replacement component safely and effectively.

Function and Role of the Oven Ignitor in Gas Valve Sequencing and Heat Regulation
The 5303935067 Frigidaire Range Flat Oven Ignitor 3-1/4″ is a resistive ceramic heating element that serves as the initiation device for gas flow and flame establishment in many Frigidaire ranges. In normal operation the ignitor must heat to a high incandescent temperature and draw sufficient current so the oven’s control circuit or gas valve senses a ready condition and permits the valve to open.Because this part is a flat, 3-1/4″ element, its physical dimensions, mounting orientation and terminal style determine mechanical and electrical compatibility with the factory wiring harness and valve assembly; installers should compare the element length, bracket shape and connector type to the original part before replacement.
- Primary role: provide heat and current draw that signals the gas valve to open in the correct ignition sequence.
- Common failure symptoms: long ignition delay, continuous clicking, weak or no flame, or the oven cycling without maintaining temperature.
- Diagnostic checks: visual inspection for cracks, resistance/continuity test with a multimeter, and an operational amp-draw test with the oven powered to verify the ignitor reaches required current.
- Compatibility reminder: match length, mounting, and terminal configuration rather than only model numbers to ensure proper sequencing and heat regulation.
Technically, the ignitor functions as both a heater and a current-limited conductor; its warm-up curve defines the timing of gas valve actuation. A partially degraded element can still glow yet fail to reach the electrical characteristics needed to hold the valve open, which produces intermittent ignition or extended warm-up times. For field service, measure resistance to confirm an open or shorted circuit and use an amp clamp during a live test to determine whether the current draw reaches the control threshold. When replacing a defective ignitor,disconnect electrical power and gas supply,confirm the replacement part matches the original physical and electrical interfaces,and retest the ignition sequence after installation to verify the valve,ignitor and control board are coordinating correctly.

How the 5303935067 Frigidaire Range Flat Oven Ignitor 3-1/4″ Operates Within the Range’s Ignition and Control Circuitry
5303935067 Frigidaire Range Flat Oven Ignitor 3-1/4″ is a hot-surface, resistive heating element used to initiate gas flow in many Frigidaire ranges. When the oven control calls for heat, line voltage is applied to the ignitor circuit; the ignitor draws current and rapidly heats to a red glow. In most domestic gas ranges the ignitor is either placed in series with the oven safety (gas) valve or its current draw is monitored by the control board-once the ignitor reaches the required temperature/current threshold, the safety valve is energized and gas flows to the burner where the glowing ignitor lights it. The component’s electrical behavior (cold resistance and hot-current draw) and its physical dimensions (flat, 3-1/4″ length) determine whether it will reliably reach the needed temperature to trigger valve operation or be detected by electronic current-sensing circuits.
- Slow or delayed glow and extended preheat times
- Control attempts to ignite repeatedly or shows ignition-related error codes
- Oven receives power and control signals but burner never lights
- Open circuit or high cold-resistance when measured with a multimeter
Technicians should verify compatibility by matching the part number, terminal style, mounting bracket, and the 3-1/4″ element length to the replacement listing; physical fit and alignment relative to the gas port affect ignition reliability. For troubleshooting, confirm mains power is removed, then check continuity and cold resistance across the ignitor leads-an open circuit indicates a failed element, while a measurable but unusually high resistance often predicts slow heating and marginal current for valve operation. Also inspect connectors and the safety valve wiring: a functional ignitor that does not permit sufficient current (due to internal degradation or poor connections) can cause the control board to time out or attempt multiple ignition cycles, so replacement decisions should consider both the ignitor condition and the upstream control/safety components.

Common Failure Symptoms and Measurable Diagnostic Indicators of Ignitor Wear
The oven ignitor performs two linked functions: it converts electrical energy into heat to achieve the surface temperature required to open the gas valve, and it provides the steady current draw the control system uses as a confirmation that the burner can be safely ignited. The 5303935067 Frigidaire Range flat Oven Ignitor 3-1/4″ is a flat-style hot-surface ignitor designed for direct replacement in compatible Frigidaire ranges; match the physical length, mounting plate, and terminal type to the oven model to ensure mechanical and electrical compatibility. In normal operation the element should glow brightly and reach its operating temperature quickly enough to allow the gas valve to open; a dim, slow, or intermittent glow indicates reduced emission from the ceramic element and often precedes complete failure.
Technicians use measurable indicators to distinguish a failing ignitor from issues elsewhere in the ignition circuit. First, verify continuity and cold resistance at the ignitor terminals with a digital multimeter-an open circuit indicates a failed filament. Second,observe operating behavior: measure the time from initial power application to a visible bright red glow (glow time),and measure live current draw under operating voltage with a clamp metre; both values should fall within the manufacturer’s service range for that ignitor type. when an ignitor exhibits elevated cold resistance, abnormally long glow time, reduced live current, or intermittent continuity under load, it will typically cause delayed ignition, repeated valve cycling, or inability of the gas valve to stay open even tho gas is supplied.
- Delayed ignition or long glow-up time during start sequence.
- Dim or uneven glow compared with a known-good ignitor.
- open circuit (no continuity) when measured cold.
- Lower-than-expected operating current or intermittent current under load.
- Oven fails to reach temperature or cycles frequently during use.

|---|---|
| Cold resistance (Ω) | measure at room temperature; compare with OEM spec. An open or significantly changed resistance is a primary failure indicator. |
| Glow time (s) | Time to reach a bright red glow after power applied. Prolonged glow time suggests reduced emission and inability to drive the gas valve. |
| Operating current (A) | Measured with the ignitor energized. A sustained current below the expected range for the oven model may prevent valve activation. |
Replacement Considerations, Model Compatibility and Step‑by‑Step Installation Requirements
The 5303935067 Frigidaire Range Flat Oven Ignitor 3-1/4″ is a flat ceramic-glass radiant ignitor that produces the heat necessary to actuate the oven’s gas safety valve by drawing current and reaching a red‑hot glow. Functionally it is indeed a resistive heating element rather than a sensor: when the element heats to its operating temperature it allows the valve/ignition circuit to energize. Compatibility depends on matching the physical envelope (the 3-1/4″ overall length and mounting tab position), the terminal style (spade, pigtail, or connector type), and the electrical characteristics (cold continuity and expected warm resistance range for the control circuit). A part with the correct appearance can still fail to operate if the resistance or connector type does not match the original, or if the mounting prevents proper oven chamber alignment and clearance from the burner cup.
Replacement requires basic electrical verification,mechanical fit checks,and controlled testing. Before removal, disconnect electrical power and close the gas supply; verify continuity with a multimeter and inspect the mounting bracket, insulating grommet, and lead wire condition. During installation ensure the ignitor sits at the same orientation and depth relative to the burner orifice and that the connector is fully seated with no exposed conductors. After reassembly, restore power and gas, observe the ignitor warm-up and valve actuation sequence, confirm a stable flame, and monitor the oven for correct ignition timing and absence of gas odor.
- Verify: physical length, mounting tab location, and terminal style before ordering.
- Electrical test: measure continuity and compare to OEM specification or known-good unit.
- Mechanical: ensure ceramic insulator and grommet are intact to prevent heat transfer to wiring.
- Post-install: perform a functional ignition test and inspect for consistent flame and cycling.
| Item | Description |
|---|---|
| Length | 3-1/4″ overall element length; critical for positioning in burner cup. |
| Mounting | Tab orientation and screw hole spacing must match the oven floor bracket for secure fit. |
| Terminals | Spade or pigtail connectors must match harness; poor fit causes intermittent ignition. |
| Electrical check | Cold continuity verifies filament integrity; abnormal open or short indicates failure. |
Q&A
What appliances is the 5303935067 Frigidaire flat oven ignitor compatible with?
The 5303935067 is an OEM replacement hot surface (flat/blade) ignitor used on many Frigidaire/Frigidaire Gallery ranges and some related brands/models (Kenmore, white‑Westinghouse) that use the same ignitor style and mounting. Always verify compatibility by checking your range model number or the manufacturer parts list – match the part number, mounting pattern, and electrical connector type before buying.
What are the common symptoms that indicate this oven ignitor has failed?
Typical signs of a failing or failed hot surface ignitor include: the oven won’t light at all; very long preheat times; the ignitor glows very weakly or not at all; the gas safety valve clicks but no gas lights; or inconsistent baking temperatures. A weak ignitor may glow but not draw enough current to open the gas valve.
How do I test the 5303935067 ignitor to confirm it is bad?
Turn power to the range off and disconnect the ignitor’s wiring. Use a multimeter set to ohms to check for continuity. A healthy hot surface ignitor will show a low resistance (a few tens of ohms); an open circuit or very high resistance indicates failure. For a live test, a technician can measure current draw with a clamp meter while the ignitor is powered - a functioning ignitor will draw several amps when hot; a significantly lower current means it’s weak and should be replaced. always disconnect power before any bench testing.
Can I replace the ignitor myself,and what are the safety steps?
Yes,a competent DIYer can replace this ignitor,but follow safety precautions: turn off electrical power at the breaker and shut off gas if applicable,remove oven racks and access panels,note wire connections,and allow the oven to cool. Avoid touching the ceramic/glowing surface with bare hands (oils can shorten its life). Replace the ignitor, reconnect wires securely, restore power/gas, and test. If you’re uncomfortable with gas or electrical work, hire a qualified technician.
How do I remove and install the 5303935067 ignitor? Any special tips?
Typical replacement steps: disconnect power/gas,access the oven cavity (lower panel or broiler compartment),remove mounting screws holding the ignitor to the burner assembly,gently pull it out to access the quick‑disconnect spade wires,disconnect old ignitor and connect the new one,re‑mount and secure it so the element is positioned the same as the original,and restore power to test. Keep screws and heat shields in their original orientation; do not overtighten the ignitor mounting screws. If connectors are corroded, replace or clean them for a reliable connection.
Is the 3-1/4″ measurement the overall length or the glow element length, and why does it matter?
The 3-1/4″ designation refers to the length of the flat/glow element portion used for fit and clearance inside the burner cavity. Matching this dimension is notable so the ignitor sits in the correct position relative to the gas port and mounting bracket. If the shape or length differs, ignition performance can be poor or the ignitor may not fit the bracket.
What should I expect to pay and where can I buy this part?
Prices vary depending on source (OEM vs aftermarket) and region; the part itself is generally inexpensive compared with labor costs if you hire a technician. You can buy the 5303935067 from appliance parts retailers, authorized Frigidaire dealers, and many online marketplaces. Prefer OEM or reputable aftermarket sellers and confirm returns/exchange policies in case it’s the wrong fit.
After replacing the ignitor, the oven still won’t light – what else should I check?
If the new ignitor glows but the oven still won’t light, check the following: wire connections for corrosion or loose terminals, the gas safety/solenoid valve (might potentially be faulty even with a good ignitor), the oven control board or spark/gas control circuitry, and that gas supply is on. A weak control board or defective gas valve can prevent ignition even with a good ignitor – if uncertain, have a qualified appliance technician diagnose the remaining components.
Final thoughts
The 5303935067 Frigidaire Range Flat Oven Ignitor 3-1/4″ serves as a critical component in the oven’s ignition system, providing the heat and electrical characteristics necessary to reliably ignite the burner and maintain consistent operating temperatures. as a compact, purpose-designed ignitor for compatible Frigidaire ranges, it directly impacts cooking performance, energy efficiency, and overall appliance reliability, making it an important part to consider when addressing ignition-related symptoms.
Accurate diagnosis and appropriate replacement are essential to restore safe, efficient oven operation and to avoid needless repairs. Symptoms such as prolonged glow time, intermittent ignition, or complete failure to light should prompt testing of the ignitor along with verification of related systems (gas supply, safety valves, and controls).When replacement is required, using the correct 5303935067 specification or an approved equivalent and following proper installation practices – or engaging a qualified technician – helps ensure the appliance returns to reliable service while maintaining safety and performance standards.
