316237805 Frigidaire Ignitor orifice Assembly is a service-replacement component for gas-fired cooking appliances that combines the gas metering orifice with the ignition interface used to light a burner.The assembly is a small precision mechanical part-typically consisting of a metering orifice (a calibrated orifice seat), associated fittings and mounting hardware, and the ignition interface or mounting location for the ignitor element-designed to control fuel flow and present the ignition source in the correct position relative to the burner.
inside the appliance the ignitor orifice assembly regulates the amount and direction of gas delivered to a specific burner while positioning the ignitor so that the supplied fuel can be reliably ignited. It interfaces directly with the appliance gas valve/manifold,the burner head,and the ignition system (hot-surface ignitor or spark ignition module),and its performance affects combustion stability,ignition timing,and flame shape. Proper orifice size, sealing and alignment are important for maintaining correct manifold pressure, preventing delayed ignition or partial combustion, and ensuring safe, repeatable operation of the burner circuit.
In the article that follows,readers will find a technical overview of how the 316237805 assembly functions,the typical appliances and models in which it is used,and how to verify compatibility with replacement parts. The guide will describe common failure symptoms (for example weak or intermittent ignition,delayed ignition,sooting or gas odor),diagnostic steps to isolate orifice versus ignitor or valve issues,and practical replacement considerations such as orientation,sealing,torque,and post-replacement leak and ignition checks. Safety precautions and relevant measurement checks are also discussed to help technicians, engineers, and appliance owners assess and address issues without relying on general marketing claims.

Function and Role of the ignitor Orifice in Frigidaire Gas Burner Systems
The 316237805 Frigidaire Ignitor Orifice Assembly is a precision-machined component that meters the gas delivered to the burner port immediately adjacent to the ignitor. In gas burner systems the orifice controls volumetric flow and local pressure drop so the ignitor sees a predictable fuel-air mixture; this stabilizes ignition timing and flame shape. Proper sizing and alignment of the orifice relative to the ignitor tip determine whether a quick, stable ignition occurs or whether you see delayed ignition, fluttering, or yellow tipping caused by rich mixtures or partial obstruction.
Functionally, the orifice behaves as a calibrated restriction: small changes in orifice diameter, downstream pressure, or dirt accumulation produce measurable changes in flame height and stability. Technicians use bench measurements and visual flame inspection to confirm correct operation-symptoms of a compromised orifice include slow lighting, intermittent flame loss when set to low, or increased cooktop noise from turbulence. The 316237805 assembly is intended for specific Frigidaire range models and should be replaced with the same specification to preserve combustion characteristics; verify model fitment and inspect for debris, corrosion, or deformation before installation.
- Typical observable issues: delayed ignition, weak or yellow flame, intermittent burner operation.
- Common causes: clogged orifice, misalignment with ignitor, incorrect replacement size, or compromised sealing.
- Service actions: clean with appropriate non-abrasive methods,confirm orifice diameter and pressure,replace when damaged.

How the 316237805 Frigidaire ignitor Orifice Assembly Works Inside the Appliance
the 316237805 frigidaire Ignitor Orifice Assembly is a combined gas metering and ignition-positioning component that controls how fuel reaches the burner and where the ignitor applies heat or a spark.Inside the appliance the assembly mounts at the burner inlet and contains a precision orifice that limits flow to the burner’s design BTU rating while providing a stable, repeatable gas jet for ignition. The ignitor element in the assembly-either a hot surface/glow-type or an electrode for spark ignition depending on the model-must sit at a defined distance and orientation relative to the orifice so the gas-air mixture reliably lights on each cycle; any change in orifice size, seal integrity, or ignitor spacing directly changes ignition timing, flame shape, and combustion quality.
In practical service, technicians use the assembly as both a functional and diagnostic reference: symptoms such as delayed ignition, persistent yellow tips, soot buildup, or a weak flame ofen trace back to a partially blocked or incorrectly sized orifice, a misaligned ignitor, or a deteriorated gasket resulting in leakage or air infiltration. Typical checks include visual inspection for carbon or debris, confirming the ignitor continuity or heater resistance, and verifying the orifice matches the appliance’s model-specific specification before replacement. For field compatibility, match the 316237805 part number to the oven or range model and confirm mounting orientation and thread/type; replacing with an off-spec orifice changes burner output and can affect safety interlocks or the control module’s ignition sensing.

common Failure Symptoms and Diagnostic Indicators of the Ignitor Orifice Assembly
The 316237805 Frigidaire Ignitor Orifice Assembly combines the ignition electrode and the gas orifice into a single, positioned module that both produces the ignition spark (or hot surface where applicable) and shapes the initial gas jet. In normal operation this assembly aligns the electrode tip with a concentrated orifice flow so the ignition energy reliably contacts the fuel-air mixture; when the orifice is partially blocked, the electrode is shifted, or the ceramic insulation is cracked, ignition behavior will change markedly. This component is supplied as an OEM replacement for specific Frigidaire gas ranges and cooktops – verify model cross‑reference and connector type before installation to ensure proper fit and electrical compatibility.
- Burner fails to light but ignitor sparks consistently – indicates possible orifice blockage, misaligned orifice-to-electrode spacing, or an upstream gas supply/valve issue.
- Delayed ignition or repeated clicking – suggests partial obstruction, degraded electrode insulation, or intermittent connection at the harness.
- Weak, yellow or fluttering flame after ignition - often caused by a restricted orifice or incorrect orifice sizing for the gas type (natural vs LP).
- No spark or no continuity at the electrode leads – electrical open circuit in the ignitor element or damaged wiring/connector.
- visible cracks, corrosion, or carbon buildup on the electrode or ceramic – visual evidence supporting replacement rather than adjustment.
| Item | Description |
|---|---|
| Continuity / Resistance | Measure electrode/leads with a multimeter and compare to the service manual specification; open circuit indicates failure. |
Diagnosing faults requires a mix of visual inspection, simple electrical checks, and live observation under controlled conditions.Use a multimeter to check continuity and insulation resistance, observe spark behavior with the control cycle engaged, and inspect the orifice bore for deposits or deformation; if the ignitor glows but flame does not establish, confirm gas valve operation and correct manifold pressure before replacing the assembly. When replacing the 316237805 Frigidaire Ignitor Orifice Assembly, ensure electrode gap and orifice alignment match the original geometry and that replacement parts are rated for the appliance’s fuel type to avoid recurring faults.
Compatibility, Replacement Considerations, and Installation Procedure for 316237805
The 316237805 Frigidaire Ignitor orifice Assembly functions as the metering and delivery component that directs gas to the ignitor/ignition port and helps establish the correct flame geometry for reliable ignition. The orifice is a precision orifice and mounting fitting rather than an electrical ignitor; its diameter and seating determine flow rate and therefore flame size, response time, and combustion stability. Incompatible orifice size, damaged threads, or a degraded gasket will change pressure drop and can produce slow ignition, repeated sparking, or a weak, sooty flame. Verify the oven or range model and the appliance’s gas type (natural vs. LP) before ordering or installing this assembly, because conversions require a different orifice or conversion kit and improper substitution alters burner performance and can create safety hazards.
- Confirm model number and gas type; cross-reference 316237805 against the appliance parts list.
- Check sealing surfaces, gasket condition, and thread integrity before installation.
- Replace the orifice assembly if corroded, deformed, or if the orifice hole is obstructed.
- after installation perform a leak check and observe flame characteristics under normal operating pressure.

| Part | 316237805 Frigidaire Ignitor Orifice Assembly (OEM fit for specified Frigidaire models) |
| Function | Precision gas metering to ignitor/ignition port; influences flame size and ignition reliability |
| Compatibility | Model-specific; verify appliance model and required gas type before replacement |
Installation practice: shut off gas and power, remove access panels to reach the burner/ignition assembly, and support any piping while loosening fittings to avoid strain on adjacent components. Clean the orifice seat and mating surfaces of scale or debris before fitting the new assembly; finger-start threads then torque to the manufacturer’s specification to avoid distortion or leaks. Reconnect wiring or electrode supports as required, restore gas, perform a soap-bubble or electronic leak test on all fittings, and cycle the appliance to confirm ignition timing and flame quality-look for a stable, primarily blue flame with minimal yellow tipping. If ignition remains slow or irregular after a correct assembly replacement, test the ignitor element and control valve as those components, rather than the orifice, will frequently enough be the root cause of persistent ignition problems.
Q&A
What is the 316237805 Frigidaire Ignitor orifice Assembly and what does it do?
The 316237805 ignitor-orifice assembly is a combined component used on some Frigidaire gas cooktops/ranges that both meters the gas flow (the orifice) and provides the ignition source (the ignitor or spark module). The orifice is a small calibrated opening that determines gas flow/BTU to the burner; the ignitor creates the spark or glow to ignite that gas. Together they control and initiate combustion at a surface burner.
How do I know if the 316237805 will fit my Frigidaire appliance?
Check the model number plate on your appliance and cross-reference it with the part listing from Frigidaire or an authorized parts distributor. The safest method is to search the appliance model number against the OEM parts diagram or contact Frigidaire support. Do not rely only on visual similarity; identical-looking parts can have different orifice sizes or electrical connectors.
What symptoms indicate the ignitor-orifice assembly needs replacement?
Common signs include: burners that click but don’t light,no spark or glow from the ignitor,weak or uneven flames,burners that take a long time to light,or a persistent gas odor near a burner. If cleaning doesn’t restore normal operation,a failing ignitor,a clogged orifice,or a damaged assembly may be the cause.
Can I replace the 316237805 myself? What safety precautions and tools are required?
Many homeowners with basic mechanical skills can replace this part, but gas work has inherent risks. Safety steps: disconnect electrical power to the range, shut off the gas supply, and work in a well-ventilated area. Tools typically include screwdrivers, an adjustable wrench, and possibly pliers. After installation, perform a gas-leak check (see below). If you are uncomfortable working on gas appliances or if local codes require it, hire a qualified technician.
What are the basic installation and post-installation tests I should perform?
Typical steps: remove grates and burner caps,disconnect the ignitor wiring,remove mounting screws and the old assembly,install the new assembly with correct orientation,reconnect wiring,reassemble the burner. Before reapplying full use,restore gas and electrical power and perform a leak check using a soapy-water solution on threaded gas connections (look for bubbles-do not use an open flame). Light the burner and observe: it should ignite quickly, the flame should be stable and mostly blue, and there should be no gas smell. If ignition is delayed or flame is yellow, shut off the appliance and troubleshoot further.
Can I clean or unclog the orifice instead of replacing the assembly?
Yes,if the orifice is simply clogged you can sometimes clear it with compressed air or a fine,non-metallic probe. Be careful not to enlarge or damage the orifice hole-never drill or file it. Remove loose debris and reassemble. If the ignitor portion is failing (no spark or weak glow) or the orifice is severely corroded/damaged, replacement is recommended.
why is the flame yellow or weak after installing a new ignitor-orifice assembly and how can I fix it?
A yellow or weak flame can be caused by a partially clogged orifice, incorrect orifice size, improper burner cap placement, incorrect air shutter/air mixture, low gas pressure or a faulty regulator. First confirm the burner cap is seated correctly and the orifice hole is clean. If the problem persists, verify you have the correct OEM part (orifice size) for your model and check gas supply pressure or regulator function-thes checks are best done by a technician.
How much does the 316237805 typically cost and where can I buy a genuine replacement?
Prices vary by seller but these assemblies commonly cost in the low tens to a few dozen dollars for OEM parts. Purchase from Frigidaire’s official parts store,authorized appliance parts distributors,or reputable online retailers. Always verify the OEM part number and your appliance model before buying to ensure you get a genuine, correctly sized part. Also check the seller’s return policy and warranty.
