316237805 Frigidaire Ignitor orifice Assembly is a service-replacement gas-ignition subassembly used on Frigidaire gas cooking appliances. It combines a fixed gas-orifice-used to meter fuel flow-with an ignitor element that initiates combustion at the burner; the part is designed as a field-replaceable unit that fits into the burner/manifold interface of compatible range and oven models.
inside the appliance the assembly interfaces directly with the gas manifold and gas valve, the burner portsand the appliance control system. The orifice portion establishes the calibrated fuel flow and, together with the burner geometry and air entrainment, helps determine the flame characteristics and heat output. The ignitor element provides the energy required to ignite the metered gas and is monitored by the control electronics and safety devices; proper operation thus affects combustion stability, temperature regulationand safety interlocks (for example, valve lockout on failed ignition or flame sensing feedback).
In this article you will find a technical overview of how the 316237805 assembly functions and how it integrates into the appliance gas and ignition systems, guidance on compatibility and part selection (including orifice sizing and mounting interfaces), common failure symptoms to recognize, diagnostic checks a technician or engineer can use to isolate faultsand practical replacement considerations such as sealingorientationand post-installation leak and operational checks. The goal is to provide the technical context needed to assess, troubleshootand safely replace the component when required.

Function and Role of the ignitor Orifice Assembly in Frigidaire gas Burners
The 316237805 Frigidaire Ignitor Orifice Assembly is a combined component that locates the spark electrode and meters the small volume of gas required for reliable ignition on Frigidaire burners. In operation the assembly’s calibrated orifice establishes a controlled flow and pressure drop to the ignition pocket while the electrode is held at a fixed distance from the burner cap, so the spark occurs where fuel and air mix reliably.Because the orifice diameter and the electrode position determine local gas velocity and mixture, this part directly affects ignition timing, initial flame shapeand susceptibility to blow-off or delayed light.
Technicians should view the unit as both a flow-control element and a positioning fixture: compatibility depends on matching the orifice sizing and manifold pressure to the appliance’s gas type (natural gas versus propane/LP) and on correct electrical connection for the ignitor. Practical service steps include confirming the part number against the appliance model, inspecting the orifice for contamination, verifying the electrode gap and insulation integrityand ensuring gaskets/seals seat to prevent leakage. Common observable issues and service checkpoints are listed below to aid troubleshooting.
- Symptoms of a problem: repeated clicking without ignition, delayed light, yellow or irregular flame, gas odor before ignitionor visible soot.
- Common causes: clogged orifice, shifted/loose electrode, cracked insulatoror incorrect orifice for the gas type.
- service actions: clean or replace the orifice assembly, confirm correct part number and gas conversion, check wiring and spark continuityand verify proper sealing during reassembly.

How the 316237805 Frigidaire Ignitor Orifice Assembly Works: Flow, Ignitionand Integration
316237805 Frigidaire Ignitor Orifice Assembly integrates a precision gas orifice with the ignition mounting so that fuel metering and spark/hot-surface initiation are mechanically aligned. The orifice controls volumetric flow from the manifold to the burner ports; its diameter and position determine local gas pressure and mixture at the burner head, which directly effect flame stability and heat output. The ignitor portion-either a spark electrode or a hot-surface element depending on the appliance model-must present the ignition energy at the correct time and position relative to the orifice jet to ensure reliable, repeatable ignition. Proper sealing, correct orifice sizingand secure electrical connection are essential for leak-free operation and predictable combustion behavior in compatible Frigidaire gas ranges and ovens.
The assembly’s operational behavior is straightforward to diagnose: restricted or partially clogged orifices reduce flow and produce weak or yellow flames, while a degraded ignitor leads to delayed ignition, repeated sparkingor failure to light despite correct gas pressure. Technicians should verify manifold pressure, inspect the orifice for deposits, confirm the ignitor type and its electrical continuity, and check electrode alignment with the burner ports. In practical repair scenarios, cleaning carbon buildup around the orifice or replacing the entire 316237805 assembly can restore correct flame pattern and ignition timing; when replacing, match orifice size and ignitor configuration to the appliance model to maintain safe combustion characteristics.
- Features: integrated metering and ignition alignment, model-dependent ignitor type.
- Common symptoms of failure: delayed ignition, continuous sparking, weak/yellow flame.
- Typical checks: visual port inspection, continuity test of ignitor, manifold pressure verification.

Common failure Symptoms and Measured Parameters Indicating Ignitor Orifice Assembly Faults
The 316237805 Frigidaire Ignitor Orifice Assembly combines the gas metering orifice with the ignition electrode mounting to create a repeatable ignition path and stable flame for compatible Frigidaire gas cooktops and ranges. When the orifice or electrode is partially blocked,eroded,misaligned,or has a poor seal,the burner will display delayed ignition,hard ignition with multiple sparks,a small or lifting flame,or persistent gas odor prior to lighting.Mechanical wear or carbon build-up on the orifice changes the effective jet size and flow pattern, while electrode spacing and insulation condition determine spark gap performance; both affect flame establishment and sensing behavior without necessarily impacting other gas system components like the valve or regulator.
- Common operator symptoms: delayed ignition, continuous sparking after flame ignition, sooty or yellow flames, intermittent burner lightingor complete failure to light.
- Measurable electrical parameters: ignition spark presence (visual or peak voltage), electrode continuity/insulation resistanceand flame-sensing rectification current.
- measurable gas parameters: orifice condition (visual/diameter), manifold or burner inlet pressure (inches W.C.)and steady-state flame stability under load.
| Item | Description |
|---|---|
| Ignitor continuity | Low resistance or closed circuit for electrode assemblies; open or infinite resistance indicates a broken led or internal fault. |
| Manifold pressure | Typical residential gas range pressure should read within the manufacturer’s specified range (commonly around 3-5 inches W.C. for natural gas); important deviation can mimic an orifice fault. |
| Flame sensing current | Rectified current in the microamp range; values below the appliance spec indicate poor flame contact or degraded electrode position. |
Technicians diagnose faults by combining visual inspection, static electrical checksand dynamic measurements under ignition. A handheld multimeter will confirm continuity and insulation resistance, while a high-voltage probe or observation confirms spark generation; a manometer verifies supply/manifold pressure and a clamp-on ammeter or microamp meter measures flame rectification when applicable.Practical repair decisions are based on measured deviations-replacing the 316237805 assembly is warranted when the orifice is visibly damaged, the electrode cannot be realigned to specor measured parameters remain out of range after cleaning and verifying supply pressure and wiring.
Replacement considerations and installation Procedures for the Ignitor Orifice Assembly
The 316237805 Frigidaire Ignitor Orifice Assembly is the calibrated gas metering component that seats between the gas valve and the burner throat to provide a controlled jet of fuel to the ignitor/burner.Proper function depends on correct orifice diameter, thread fitand sealing at the seat; even small deviations in port size or misalignment change the gas velocity and can produce delayed ignition, unstable flame shapeor incomplete combustion. When selecting this replacement part, verify the service manual or parts list for the exact model fit – the assembly must match the valve outlet geometry and any integrated mounting or wiring features to avoid altered flow characteristics or improper sealing with the burner manifold.
Replacement requires careful planning, inspection of mating surfacesand post-installation verification. Before removal, isolate gas and electrical power and ensure the appliance is cool; during installation, protect the orifice seating surface from debris and avoid cross-threading the fitting. After hand-starting the threads and seating the assembly, tighten to the manufacturer’s recommended specification, restore gasand perform a leak test and multiple ignition cycles while observing flame stability, colorand ignition timing. If ignition remains slow or the flame is yellow, also inspect electrode gap, ignitor continuityand manifold pressure, as those conditions can indicate an orifice mismatch or additional system faults.
- Shut off gas and power, ventilate the area, then remove access panels to reach the burner throat.
- Remove the old orifice assembly, inspect the seat and gasketand clean any carbon or debris from the port.
- Install the new orifice,hand-start threads to avoid cross-threading,then tighten to the specified torque in the service documentation.
- Restore gas and perform a leak test (soap solution or electronic detector), then run several ignition cycles while checking flame shape and stability.
- If problems persist, verify ignitor resistance, electrode alignmentand manifold pressure before replacing additional components.

Q&A
What is the 316237805 Frigidaire Ignitor Orifice Assembly?
The 316237805 Frigidaire Ignitor Orifice assembly is an OEM replacement part that combines the gas orifice (which meters gas flow to a burner) and the ignitor/electrode (which ignites the gas). It is used on compatible Frigidaire gas ranges/ovens to ensure reliable ignition and correct gas delivery to a specific burner or oven burner port.
How do I know if this assembly is compatible with my Frigidaire appliance?
Confirm compatibility by matching the part number (316237805) to your appliance parts list or service manual and by checking your appliance model number. many parts websites and frigidaire parts dealers let you enter the appliance model to verify fit. Also visually compare the existing assembly to the replacement-mounting points, connector typeand orifice size should match.
What are the common symptoms of a failing ignitor orifice assembly?
Typical symptoms include a burner that won’t light, delayed ignition (a long hiss before lighting), weak or intermittent flames, clicking without ignition (on spark systems)or a yellow/orange (rather than blue) flame. In ovens a weak ignitor can cause the oven to heat slowly or not reach temperature.
How can I test whether the ignitor orifice assembly is bad?
Visually inspect for cracks, corrosionor carbon buildup on the electrode/orifice. Perform continuity and resistance checks with a multimeter on the ignitor/electrode circuit if it’s a hot surface ignitor; a complete open circuit indicates failure. For glow-type oven ignitors, a current draw test with a clamp ammeter (or comparing to manufacturer specs) can show if the ignitor is too weak to open the gas valve.If ignition spark is absent on a spark ignitor, verify the spark module and wiring before replacing the assembly.
Is it safe and practical to replace this part myself?
yes, a competent DIYer can replace it, but you must first shut off gas and electrical power to the appliance. Use proper tools, avoid damaging the new orifice, and follow manufacturer or service manual instructions. If you are not comfortable working with gas connections or electrical componentsor if the appliance requires burner calibration after replacement, hire a trained appliance technician.
What tools and materials are typically needed for replacement?
Common tools include a nut driver or wrench set (for orifice fittings/mounting screws), screwdriver, pliers, an adjustable wrench for any gas fittings, a multimeter for verificationand pipe thread sealant/gas-rated joint compound if required by the manufacturer. Have work gloves and eye protection. Do not use non-rated sealants on gas fittings-follow Frigidaire instructions.
How should I clean or maintain the ignitor orifice assembly to prolong its life?
Keep the burner area free of food debris and grease. If the electrode or orifice is dirty, power and gas must be off before gently cleaning with a soft brush or compressed air-do not file or enlarge the orifice. Avoid touching the ignitor ceramic or hot surface with bare hands; oils can shorten life. If corrosion or physical damage is present, replacement is recommended rather than cleaning.
How do I troubleshoot ignition problems before replacing the assembly?
First ensure the appliance has power and gas supply. Clean burner ports and check for blocked holes. For spark ignition systems, listen for the spark and inspect wiring to the spark module and ground connections. For glow ignitors, check for visible glow when calling for heat and test electrical continuity. Verify that safety components (thermocouples, flame sensors, gas valve) are functioning-sometimes a bad valve or control, not the ignitor, causes ignition failure.
