316237704 Frigidaire Ignitor/Orifice Assembly is a combined ignition and gas metering component used in frigidaire gas cooking appliances; it integrates a gas orifice that meters fuel flow with an ignitor element that initiates combustion. The assembly is a field-replaceable part typically mounted at the burner or manifold and is designed to ensure a controlled and repeatable ignition event for the oven or range burner.As a mechanical and electrical subassembly, it comprises the physical orifice sized for a specific gas type and the ignitor element (hot surface or spark-type depending on the model) with the necessary mounting and sealing hardware.
Inside the appliance, the ignitor/orifice assembly sits at the intersection of the gas delivery and ignition subsystems. It directly interacts with the appliance gas valve and manifold to regulate the quantity of gas delivered to a burner, and with the control circuitry and safety systems that time and validate ignition. Proper operation requires correct orifice sizing for the gas type and sufficient ignitor performance to cause reliable light-off; failures can affect burner flame characteristics, temperature control, and safety interlocks managed by the control board or thermally based safety devices.
in this article readers will find a technical overview of how the 316237704 assembly functions,guidance on model compatibility and gas-type considerations,common failure symptoms (for example no ignition,prolonged ignition delay,weak or unstable flame,or failure to reach set temperatures),systematic troubleshooting checks to isolate ignitor versus orifice issues,and practical replacement considerations such as verifying part number,orifice sizing,electrical connections,and basic safety precautions for gas and electrical isolation. The goal is to provide technicians, engineers, and appliance owners with the context and diagnostic starting points needed to evaluate and service the component within a gas cooking appliance.

functional Role and Electrical and Thermal Specifications of the Ignitor/Orifice Assembly in Frigidaire Gas Appliances
The 316237704 Frigidaire ignitor/orifice Assembly combines a resistive glow ignitor with a precision gas orifice to deliver reliable ignition and controlled gas flow for compatible Frigidaire ranges and ovens. Electrically, the ignitor is designed to operate on the appliance mains (typically 120 VAC in North American installations) and presents a changing resistance characteristic as it heats: higher cold resistance that falls as the element reaches operating temperature. In-service surface temperatures are high enough to ignite the burner mixture directly; the assembly must thus withstand repeated thermal cycling and maintain mechanical alignment between the ignitor tip and the orifice to ensure consistent ignition timing and flame quality.
Functionally the orifice portion meters the gas volume for the burner and must match the appliance’s fuel type and manifold pressure (natural gas vs. LP), while the ignitor provides the heat source that initiates combustion. Technicians should verify part-number compatibility and inspect both electrical continuity and ignition voltage at startup when diagnosing failures. Practical symptoms of a failing assembly include long ignition delay, weak or intermittent flame, or no glow on the ignitor; replacement requires matching the OEM orifice diameter and the ignitor’s electrical characteristics rather than relying on look‑alike parts.
- Common diagnostic indicators: no glow, steady glow without ignition, delayed ignition, or irregular flame pattern.
- Replacement considerations: fuel type (NG/LP), manifold pressure, and OEM part number matching.
- Safety notes: always de-energize and shut off gas before servicing; verify proper flame after installation.

How the 316237704 Frigidaire Ignitor/Orifice Assembly Interfaces with the burner, Gas Valve, and Control Electronics
The 316237704 Frigidaire Ignitor/Orifice Assembly integrates the ignition electrode and a calibrated gas orifice into a single serviceable unit that mounts to the burner manifold. Electrically it interfaces with the range’s ignition module or control electronics to receive timed firing commands and deliver a spark (or signal for a hot-surface element, depending on the appliance design), while the orifice provides the correct pressure-drop and flow rate to the burner. Mechanically the assembly must match the manifold flange, screw pattern, and sealing surfaces for proper alignment and safe gas containment; compatibility is determined by those dimensions and the connector type used by the appliance model.
During a normal ignition cycle the control electronics call for heat, the gas valve opens to admit fuel and the ignitor generates a spark at the burner ports; once a stable flame is detected the control system stops firing the ignitor and maintains the valve position as needed. Practical troubleshooting uses this interaction: a clicking ignitor with no flame can indicate a clogged orifice or closed/failed valve, while a steady flame without ignition pulses points to control or wiring issues. Technicians should verify mechanical fit, examine the orifice for deposits, confirm continuity and proper connector seating, and observe the control timing to determine whether the fault lies with the ignitor/orifice assembly, the gas valve, or the control electronics.
- Electrical interface: timing and voltage from the ignition/control module.
- Gas metering: orifice diameter sets flow rate and pressure drop.
- Mechanical fit: flange, screws, and sealing surfaces determine compatibility.
- Sensors and feedback: flame detection and interlocks influence ignition sequencing.
| Item | Description |

| Mechanical mounting | Flange and screw pattern that aligns the orifice with the burner manifold. |
| Orifice function | Calibrated aperture that meters gas flow; diameter is model-dependent. |
Common Failure Modes and Diagnostic Symptoms: Ignitor Open/Short, Orifice Fouling, and Flame Instability
The 316237704 Frigidaire Ignitor/Orifice Assembly integrates a resistive hot-surface ignitor with the matched gas orifice used on applicable Frigidaire ranges and ovens. The ignitor functions as a controlled heating element that must reach a specified temperature to allow the gas valve to prove a safe ignition condition; an open circuit (infinite resistance) will prevent the valve from operating and result in no ignition, while a short or abnormally low resistance can alter valve drive characteristics and sequencing. Technicians should perform a visual inspection for cracks, glazing, or damaged terminals and confirm electrical behavior with a multimeter (continuity/ohms) against the manufacturer’s specification for the exact model before replacing the assembly, since physical fit and orifice size are critical for compatibility and safe combustion performance.
- Absent ignition or no current draw – ignition circuit open or broken ignitor.
- Continuous or delayed gas flow – ignitor not reaching operating temperature or incorrect resistance.
- Weak, yellow, or lifting flame – orifice fouling, partial blockage, improper orifice size, or low inlet pressure.
- Fluttering or noisy flame – unstable airflow, misaligned burner cap, or intermittent gas supply.
| Item | Description |
|---|---|
| Ignitor open | Infinite resistance; oven/range will not light; replacement typically required. |
| Ignitor short/low resistance | Resistance near zero; may prevent proper valve sequencing or overdraw circuit; verify against OEM spec. |
| Orifice fouling | Restricted flow produces weak/yellow flame and delayed ignition; cleaning or replacement of orifice/assembly needed. |
Orifice fouling and flame instability often present with soot, yellow tips, intermittent flame, or delayed ignition times; these are practical indicators to isolate the problem to the gas passage or combustion air path rather than random electronic faults. For on-appliance diagnostics, isolate the electrical supply and measure ignitor resistance, then remove and inspect the orifice for particulate blockage or corrosion; clean with appropriate non-invasive methods (soft brush or low-pressure air) without enlarging the orifice. When gas type conversions or burner component replacements have been performed, verify that the installed orifice size and assembly match the appliance’s gas type and pressure rating, because mismatched orifices or incorrect inlet pressure are common causes of unstable combustion that cannot be corrected by electrical repair alone.
Compatibility, Replacement and Installation Procedures for 316237704: Mounting, Sealing, and Electrical Connections
The 316237704 Frigidaire Ignitor/Orifice Assembly combines the ignition element and the metering orifice into a single replaceable unit that directly affects flame establishment and gas flow characteristics. Compatibility is determined by the appliance model, the fuel type (natural gas or LPG) and the manifold pressure setting; the orifice size must match the range’s pressure and burner geometry to produce correct flame shape and heat output. Technicians should verify the appliance model and service literature or compare the existing part visually before replacement, and be aware that some Frigidaire ranges use interchangeable assemblies where the orifice insert is the only component that differs between natural and LP versions.
Proper mounting, sealing and electrical connection are critical to reliable operation and safe sealing of the combustion chamber. Before beginning work always shut off gas and electrical power, then preserve wire routing and connector orientation for reassembly. Mounting screws should be installed without distorting the assembly flange; use the appliance manufacturer’s specified fasteners or equivalent sheet‑metal screws and tighten evenly so gaskets seat uniformly. Use a high‑temperature silicone gasket or an OEM gasket to seal the combustion air path and prevent leakage; if a separate orifice retainer is present, confirm the orifice is fully seated and aligned with the burner port. Electrical connections typically use insulated spade terminals or a pigtail; ensure a good ground and route leads away from hot surfaces. After installation perform a functional check: confirm ignition sequence, observe flame pattern for lift or yellowing, and perform a soap or approved leak test at the gas joint.
- confirm part number and gas type before ordering or installing.
- Shut off gas and power, document connector/wire positions.
- Use OEM or high‑temp gaskets and avoid over‑torquing mounting screws.
- Reconnect insulated terminals and verify chassis ground continuity.
- Perform ignition, flame‑pattern, and leak tests after reassembly.

Q&A
What is the 316237704 Frigidaire Ignitor/Orifice Assembly and what does it do?
The 316237704 is a combined ignitor and gas orifice assembly used on some Frigidaire gas cooktops/ranges. The ignitor (electrode) produces the spark needed to ignite the burner, and the orifice (jet) meters the gas flow to the burner. Together they control reliable ignition and the correct flame size for that burner.
What are common symptoms that this assembly has failed?
Typical symptoms include continuous clicking without a flame, intermittent ignition, very weak or uneven flames, or a burner that lights only after a long delay and produces a yellow/orange flame. if you smell raw gas while trying to ignite, shut off the gas immediately and ventilate – that indicates an ignition failure and a potential safety hazard.
How can I test whether the ignitor/orifice assembly is the problem?
First observe: if you hear clicking but no visible spark at the electrode, the ignitor may be bad. For surface spark electrodes, a simple visual test during ignition attempts can confirm whether a spark is present. multimeter continuity tests are not always reliable for high-voltage spark electrodes, but a wholly open circuit can indicate a failed electrode. For the orifice, check for clogging or carbon deposits and compare flame behavior to other burners. When in doubt, swapping the assembly with a known-good identical part (or having a technician do so) is a practical diagnostic.
Can I clean the orifice instead of replacing the whole assembly?
Often the orifice can be clogged by debris or carbon and cleaning it can restore proper operation. Remove the orifice and clean gently with compressed air or a fine wire/needle (use caution – don’t enlarge the hole). Do not use abrasive drilling. If cleaning does not fix ignition or if the electrode is damaged, replacement of the whole assembly is recommended.
Is the 316237704 assembly interchangeable between natural gas and LP (propane) appliances?
No. Orifice sizes differ for natural gas and LP because propane requires a smaller orifice. Only use the orifice specified for your appliance and fuel type. If your range was converted to LP, ensure it uses the correct LP orifice and that the conversion was done according to Frigidaire’s instructions by a qualified technician.
How challenging is it to replace this assembly and what safety precautions should I take?
Replacement is moderate-difficulty for someone cozy with basic appliance repair.Safety steps: disconnect electrical power to the range,shut off the gas supply,and ensure the appliance is cool. Follow the manufacturer’s instructions: remove the burner components or range top as needed, unscrew the old assembly, install the new one with correct orientation, and tighten fittings without over-torquing. After installation, check for gas leaks with a soapy-water solution or a gas leak detector and verify proper ignition. If you are not confident, hire a qualified appliance technician.
Do I need special sealant or thread tape on the orifice when installing?
Follow the manufacturer instructions for your model. Many orifices are designed to seal when torqued into a manifold and do not require additional sealant. if thread compound is used,it must be rated for gas service and applied properly. Incorrect sealants or overuse can clog the orifice. When in doubt, consult the Frigidaire service manual or a licensed technician.
How do I confirm compatibility and where should I get a replacement part?
Confirm compatibility by matching your appliance model number (usually on a tag inside the oven door frame or rear panel) to the part number cross-reference. Purchase OEM Frigidaire parts from authorized dealers, Frigidaire’s parts website, or reputable appliance parts suppliers. Using genuine or exact-fit replacement parts ensures the correct orifice size, electrode spacing, and warranty coverage.
