316237704 Frigidaire Ignitor/Orifice Assembly is a combined ignition and fuel-metering component used on gas cooking appliances; the assembly typically integrates an ignitor element (either a hot surface or spark-type electrode) with a fixed gas orifice/nozzle designed to produce the correct jet size for a specific burner. As a discrete service part it replaces the mating hardware that both initiates combustion and meters the incoming gas at the burner port, and it is supplied as a preassembled unit to ensure alignment and sealing between the ignitor and orifice.
Inside the appliance the ignitor/orifice assembly interfaces directly with the gas supply, burner head, and the appliance’s ignition and safety controls. The ignitor provides the energy necessary to light the fuel (spark discharge or sustained heat for thermally activated valves), while the orifice determines volumetric flow at given inlet pressure so that the burner achieves the intended BTU output and flame geometry.Proper operation thus depends on correct orifice sizing for the fuel type and pressure, secure mechanical mounting, and electrical continuity to the control module and safety interlocks (such as flame sensing and valve sequencing).
In the article that follows you will find a technical review of the assembly’s function, common compatibility and part-number considerations, typical failure symptoms (such as, no ignition, delayed ignition, weak or yellow flame, or intermittent operation), methods for safe troubleshooting and testing, and practical replacement considerations such as fuel-type orifice sizing, sealing and alignment, electrical checks, and safety precautions. The facts is presented to help technicians, engineers, and appliance owners diagnose issues systematically and determine whether repair or replacement of the 316237704 assembly is appropriate.

Function and Role of the Ignitor/Orifice Assembly in Frigidaire Gas Appliances
The 316237704 Frigidaire Ignitor/Orifice Assembly is a combined ignition and gas metering component used on compatible Frigidaire gas ranges and ovens. Functionally, the ignitor produces the energy required to ignite the gas (either a hot-surface glow or a spark, depending on the appliance design) while the orifice is a precision‑bored nozzle that restricts and shapes the gas flow to each burner.Together these two elements control ignition timing, flame geometry, and steady-state heat output: a correctly sized orifice delivers the intended volumetric flow for the appliance’s jet pressure, and a healthy ignitor provides reliable ignition on the first cycle to prevent gas accumulation and delayed lighting events.
- Primary behaviors: initiate combustion, meter gas volume, maintain consistent flame pattern.
- Compatibility considerations: the assembly must match the appliance’s fuel type (natural gas or LP) and specified orifice diameter; mismatching orifice size alters BTU delivery and flame appearance.
- Troubleshooting indicators: delayed ignition, weak or yellow-tipped flame, soot, or frequent clicking typically point to orifice blockage, misalignment, or failing ignitor.
- Practical guidance: verify fuel type, replace with an assembly that matches the appliance service specification, and shut off gas/electric supply before servicing.
| Item | Description |
|---|---|
| Ignitor | Provides the thermal or electrical energy to ignite gas; inspect for visible glow,wear,or open circuit. |
| Orifice | Precision aperture that meters fuel; size must match appliance design and fuel type to achieve correct heat output. |
| Function | Controls ignition reliability and steady flame characteristics; both parts are required for safe combustion control. |
| Common symptoms | Slow lighting, irregular flame, soot deposition, or gas odor-each suggests inspection or replacement of the assembly. |
When servicing or replacing the assembly, technicians should reference the appliance’s parts list and conversion documentation to confirm the correct orifice diameter and ignitor type; swapping a unit with the wrong orifice or incompatible ignitor can cause underperformance or unsafe combustion. In practice, a replacement 316237704 Frigidaire Ignitor/orifice assembly will resolve issues caused by clogged orifices, cracked ignitor elements, or electrical failures, but triumphant repair also requires correct installation torque, alignment of the ignitor to the burner port, and verification of ignition timing and flame pattern after reassembly. Routine checks-visual inspection,resistance/continuity testing per service manual,and observing combustion characteristics-help determine whether the assembly or adjacent components (valves,wiring,control modules) are the root cause of a problem.
How the 316237704 Frigidaire Ignitor/Orifice Assembly Works Inside the Appliance
The 316237704 Frigidaire Ignitor/Orifice Assembly combines an electrical ignition element with a precision gas orifice to initiate and shape the burner flame inside compatible Frigidaire ranges and ovens. The ignitor converts electrical energy into a heat or spark source positioned at the burner mouth while the orifice meters the downstream gas flow from the valve; together they control ignition timing, initial flame size, and flame stability. In operation, the appliance control energizes the ignitor and opens the gas valve in a coordinated sequence so that the gas exiting the orifice encounters a reliable ignition source immediately adjacent to the burner ports.
Technically, proper function depends on matching the orifice size to the appliance’s manifold pressure and fuel type and ensuring the ignitor produces sufficient thermal or electrical energy to light the gas quickly. Typical service diagnostics include visual flame inspection (color and lift), checking the ignitor for continuity and correct electrical behavior, and confirming the orifice is free of deposits or damage. Practical examples: a slow-to-light oven frequently enough indicates a weak ignitor or partially blocked orifice, while a yellow, sooty flame can point to an orifice sized for the wrong fuel or disturbed primary air.When replacing this assembly, verify the part number, mounting orientation, and that the orifice rating matches the appliance’s gas specification and service manual guidance.
- Key service checks: visual flame quality, ignitor continuity, orifice cleanliness, and correct mounting/alignment
- Common symptoms of wear: delayed ignition, erratic flame, or flame lift/sooting
- Compatibility considerations: match fuel type (natural vs. LP), manifold pressure, and OEM mounting pattern
| Item | Description |
|---|---|
| Ignitor | Provides the heat or spark necessary for ignition; requires appropriate electrical supply and verified continuity. |
| Orifice | Precision orifice controls gas flow and initial flame shape; must match gas type and manifold pressure. |
| Service checks | Inspect for deposits or damage, verify electrical behavior, and confirm orifice sizing against the appliance specification. |
Common Failure Symptoms and Diagnostic Indicators of Ignitor/Orifice Assembly Issues
The 316237704 Frigidaire Ignitor/Orifice Assembly combines the ignition element and the gas metering orifice into a matched component engineered for specific frigidaire gas ranges and ovens. The ignitor provides the energy-either a spark or hot surface-required to reliably ignite the gas when the valve opens, while the orifice meters the flow to the burner tube to achieve the intended flame geometry and heat output. Proper function depends on the correct orifice size for the fuel type (natural gas vs. LP), correct mounting and alignment with the burner, and intact electrical connections; substituting an incorrectly sized orifice or a mismatched ignitor type will alter flame shape, combustion stability, and appliance safety interlocks.
Common failure modes manifest as observable ignition and combustion anomalies that guide diagnostic troubleshooting. Typical symptoms include delayed ignition (longer than a few seconds between valve actuation and flame),persistent or frequent clicking with no flame,yellow or floating flames indicating incomplete combustion or incorrect orifice sizing,and intermittent burner outages. Effective diagnostics combine visual inspection (soot, corrosion, or a clogged orifice), functional checks (confirming presence of spark or consistent hot-surface glow and timing), and electrical checks at the connector (continuity, correct control voltage). For example, if a spark is visible but the burner does not light, the orifice may be blocked or the valve not opening fully; if the ignitor glows weakly or takes noticeably longer to ignite the burner, the ignitor element may be degrading and drawing insufficient current.
- Delayed ignition - check ignitor glow/spark timing and valve operation.
- Yellow or sooting flame – inspect orifice size/cleanliness and fuel type compatibility.
- Continuous clicking – verify ignition module wiring and ground, and inspect for moisture or debris around the electrode.
- Intermittent operation – perform continuity and voltage checks at the assembly connector; consider swapping with a known-good unit for isolation.

Compatibility, Model Fitment, and OEM Cross‑Reference for the 316237704 Frigidaire Ignitor/Orifice assembly
The 316237704 Frigidaire Ignitor/Orifice Assembly combines a spark ignitor electrode and a precisely sized gas orifice into a single replaceable unit used on gas cooktops and ranges. the ignitor produces the spark pattern or concentrated hot spot required to reliably ignite the gas delivered through the orifice, while the orifice meters flow to establish the correct flame size and combustion characteristics. Mating this assembly to the appliance requires matching the electrical connector type and mounting geometry, the orifice diameter and thread or seat style, and the gas type (Natural vs. LP); mismatches in any of these areas can cause intermittent ignition, low flame, or improper combustion behavior rather than being resolved by replacing othre components such as the valve or control module.
Technicians verifying compatibility should cross‑reference the appliance model and service literature against the 316237704 part number and inspect several physical and electrical features before installation. practical checks include verifying the ignitor electrode polarity and connector pinout, confirming the orifice bore size and inlet thread, and ensuring the mounting screws align with the burner box and any heat shields. Field symptoms that indicate the assembly may be at fault include repeated sparking without ignition, weak or yellow flame after replacement, or a flame that lifts off the burner – each symptom can also point to valve pressure, regulator, or manifold issues, so systematic verification reduces needless part swaps.
- Compatibility checks: appliance model number, gas type (Nat/LP), orifice diameter, electrical connector, mounting pattern
| Item | Description |
|---|---|
| Orifice size | Controls gas flow; must match appliance specification for correct flame and pressure. |
| Electrical connector | Pin count, spacing and polarity must match the appliance ignition harness for reliable sparking. |
| Mounting pattern | Screw locations and heat‑shield clearance determine physical fit and thermal protection. |
Q&A
What is the Frigidaire part 316237704 (Ignitor/Orifice Assembly)?
OEM part 316237704 is a combined ignitor and orifice assembly used on certain Frigidaire gas ranges and cooktops. The ignitor (electrode) creates the spark to ignite gas and the orifice is the small jet that meters gas flow to the burner. The assembly replaces both components at once so you restore proper spark ignition and correct gas delivery for that burner.
How do I know if 316237704 is the correct replacement for my appliance?
Check your appliance model number (usually on a sticker behind the oven door, on the frame, or on the back of the unit) and confirm the OEM part number or parts breakdown in the owner’s manual or manufacturer parts list. Parts retailers and Frigidaire customer support can cross-reference 316237704 to specific models. Do not rely solely on burner appearance-verify by model and part number to ensure fit and correct orifice size (natural gas vs LPG/propane).
What symptoms indicate I need to replace the ignitor/orifice assembly?
Common symptoms include no ignition (no spark), constant clicking with no flame, delayed ignition (long puffing), weak or uneven flame, or visible damage/corrosion to the electrode or orifice. If you have clicking but no flame and you’ve confirmed gas is reaching the burner, a failed ignitor/electrode or clogged/damaged orifice can be the cause.
Can I test the ignitor/orifice assembly before replacing it, and how?
Yes. First visually inspect for cracked ceramic, bent/broken electrode, heavy carbon buildup or a clogged orifice.With the range powered and the burner control turned to light, look for a spark at the electrode; if you see spark but no flame, the orifice or gas supply might potentially be the problem.If there is no spark, check for power to the spark module and ignition switch/wiring. For glow-type oven ignitors (different design) you can measure resistance with a multimeter and compare to service specs; for spark electrodes, continuity tests are less definitive-absence of visible spark with correct module power usually means the electrode or module needs replacement. Always follow safety procedures and, when in doubt, consult the service manual or a technician.
Are there installation or safety considerations I should know before replacing 316237704?
Yes. Turn off electrical power to the appliance and shut off the gas supply before starting work. Ensure the replacement assembly is the correct part and intended for your gas type (natural gas vs propane), as orifice size differs. Install the assembly so the electrode gap and alignment to the burner are correct-an improperly positioned electrode can fail to spark or ignite. After installation, check for gas leaks (soapy water test) at connections, restore power and test ignition on low and high settings.If you are uncomfortable with gas or electrical work, hire a qualified appliance technician.
How is the ignitor different from the orifice, and why are they sold together as an assembly?
The ignitor (electrode) produces the high-voltage spark that lights the gas; the orifice is a tiny jet that meters the gas volume delivered to the burner. They are often replaced together because a damaged orifice (clogged,corroded,or wrong size) and a failing ignitor can both cause poor ignition,and the physical mounting of the two parts is usually integrated. Replacing the assembly ensures correct spark-to-flame spacing and the correct gas jet for safe, reliable ignition.
Can I clean the orifice or electrode instead of replacing the whole assembly?
Light carbon buildup on the electrode can sometimes be cleaned gently with a soft brush; a slightly clogged orifice may be cleaned with an appropriate orifice cleaning tool or carefully with compressed air. Though, do not enlarge or deform the orifice hole, and do not use wires or pins that will change the orifice size. If the electrode ceramic is cracked, the electrode is corroded, or the orifice is deeply clogged or damaged, replacement is recommended. Given the low cost of many OEM assemblies and the safety importance of correct gas metering,full replacement is often the best option.
How long does the 316237704 assembly last and what affects its lifespan?
Lifespan varies-many ignitor/orifice assemblies last several years to decades under normal use. factors that reduce life include moisture and spills that corrode electrodes, frequent heavy-duty use, rough cleaning, and poor burner maintenance (leading to clogging). Regular cleaning of burners (per the appliance manual) and avoiding excess liquid spills can extend life. If you experience repeated ignition issues, have the whole ignition system inspected to identify root causes.
Future Outlook
The 316237704 Frigidaire Ignitor/Orifice Assembly plays a central role in gas-fired Frigidaire cooktops and ovens by providing reliable ignition and controlled gas flow to the burner. As an integrated component, it helps ensure consistent ignition timing, efficient combustion and stable heat output, which contributes to safe operation, optimal cooking performance and overall appliance efficiency. proper function of this assembly is therefore important for maintaining the intended performance and longevity of the appliance.
