316237805 Frigidaire ignitor Orifice Assembly is a factory-designated replacement component used in gas-fired Frigidaire cooking appliances; it combines the mechanical orifice that meters gas flow with the ignitor assembly that initiates combustion.As a service part, it is a small metal and ceramic subassembly that sits at the interface between the gas valve and the burner, and it is typically identified by the OEM part number when ordering or specifying service replacements.
The ignitor orifice assembly governs where and how gas is delivered to the burner and provides the ignition source (either a hot surface or spark element) required to light that gas. In operation it interacts directly with the appliance’s gas valve and regulator, the burner head, the control module or thermostat that calls for heat, and any flame-sensing or safety interlock circuits. Correct installation and sizing of the orifice affect air‑fuel mixture, flame pattern, combustion stability, and safety; misalignment, blockage, or a failed ignitor can cause delayed ignition, poor flame characteristics, or safety shutdowns, so the part’s role is critical to reliable and safe appliance operation.
In this article readers will find a technical overview of the 316237805 component including its functional design, where it is typically used within Frigidaire gas ranges/ovens, and how to verify compatibility with specific appliance models. The guide will also describe common failure symptoms, recommended diagnostic steps (visual inspection, electrical continuity and voltage checks against manufacturer specifications, and gas flow/pressure considerations), practical troubleshooting tips, and replacement considerations such as proper orientation, sealing, torque, and post‑service leak testing. Emphasis is placed on safe, standards‑based procedures and on data technicians, engineers, and informed appliance owners need to make reliable repair decisions.

Function and Role of the Ignitor Orifice Assembly in Frigidaire Gas Burners
The 316237805 frigidaire Ignitor Orifice Assembly is a metering component that interfaces between the gas manifold and the ignitor/pilot tube to regulate the volumetric flow and shape of the gas jet delivered for ignition. Functionally it provides a fixed orifice diameter and mounting interface so the ignitor sees a predictable pressure drop and mass flow at rated manifold pressure; this stability is required to achieve a correct flame pattern and reliable ignition timing. The assembly must match the appliance’s fuel type and inlet pressure (natural gas vs. LP) and the oven/range model’s manifold geometry, as an incorrect orifice size or mating can produce weak flames, delayed ignition, soot, or safety-control lockouts rather than simply changing heat output.
Technicians should treat the part as a precision flow element: contamination, corrosion, or mechanical damage to the orifice or its seat will alter flow characteristics and often requires replacement rather than cleaning if the geometry has been altered. Typical service procedures include isolating the gas supply, removing the burner top or access panel, verifying gas type and pressure, and swapping the assembly for a certified replacement that matches the appliance model. Use of the correct regulator settings and conversion jets is necessary when switching fuel types; do not substitute with generic fittings that don’t match the original tolerances.
- Common symptoms of a failing orifice assembly: weak or yellow flame, delayed ignition or clicking, visible soot, and oven safety lockouts.
- Compatibility considerations: verify appliance model and gas type before ordering replacement parts.
- Maintenance tip: light deposits may be removed carefully, but distortion or pitting warrants replacement.

How the 316237805 Frigidaire Ignitor Orifice Assembly Operates Within the Burner and Ignition Circuit
The 316237805 Frigidaire Ignitor Orifice Assembly is a combined mechanical and electrical subassembly that both meters gas at the burner port and provides the ignition electrode required by the cooktop’s spark system. In normal operation the gas valve supplies low-pressure gas to the orifice while the ignition module delivers high-voltage pulses to the electrode; the orifice geometry determines the jet size and flame shape, and the electrode positioning ensures the spark originates at the gas jet for reliable combustion. Proper sealing, alignment, and a clean orifice are required for consistent flame characteristics, while a damaged electrode, broken insulator, or blocked jet produces weak flames, delayed ignition, or continuous sparking without lighting the burner.
Within the burner and ignition circuit the assembly functions as the interface between the gas delivery subsystem and the electrical spark-generation subsystem: electrically it must present correct insulation and a conductive path for the spark to jump to ground, and mechanically it must hold the jet and electrode at factory tolerances to maintain mixture and flame stability. Technicians commonly verify function by inspecting the orifice for deposits, confirming electrode continuity and insulation integrity, ensuring correct torque and seating in the burner head, and checking that the ignition module issues pulses during a lighting attempt. Practical checks include replacing the assembly with a known-good unit when symptoms persist after verifying fuel pressure and module output, and confirming model compatibility before installation to preserve orifice sizing and electrode geometry.
- Features: combined gas metering and ignition electrode,mounted in burner head for precise spark-to-gas alignment.
- Common symptoms of failure: continuous clicking without ignition, weak or uneven flame, or visible damage to electrode/insulator.
- Service checks: visual cleaning of orifice, electrode continuity test, secure mechanical seating, and verifying spark pulses from the ignition module.

Common Failure Symptoms and Measurable Diagnostic Indicators of ignitor Orifice Degradation
The 316237805 Frigidaire Ignitor Orifice Assembly meters and directs the gas feed to the ignitor/pilot jet and plays a direct role in stable flame formation and reliable ignition. When the orifice throat becomes partially blocked by carbon, corrosion, or particulate contamination, the jet velocity and pressure profile change; this produces measurable effects such as longer ignition delay, a reduced or irregular flame envelope, and incomplete combustion signatures (soot or elevated CO/CO2 balance). Compatibility with the appliance depends on thread size, seating geometry and orifice diameter, so using the correct OEM assembly ensures the intended flow characteristics and sealing; an undersized or mismatched orifice alters gas flow and may trigger control-system lockouts or repeated safety shutoffs on Frigidaire ranges and ovens.
- Delayed ignition (> a few seconds) or repeated ignition attempts
- Small, lifting, or flickering pilot/ignitor flame
- Visible soot or blackening around burner ports
- Frequent safety lockouts or control errors during bake/boil cycles
- Measured pressure drop across the orifice higher than expected
| Item | Description |
|---|---|
| Ignition delay | Time from actuator command to sustained flame; values greater than a few seconds indicate restricted flow or weak ignitor output |
| Supply pressure | Measured with a manometer at the regulator or manifold; residential natural-gas appliances typically operate in the low inches water column range (refer to OEM spec) |
| Flame appearance | Short, yellow, or lifting flame indicates poor orifice flow, while a stable blue cone indicates correct flow and mixture |
Technicians verify orifice health by combining visual inspection with quantitative checks: inspect the orifice for deposits and pitting, measure manifold and immediate upstream pressure with a manometer, and time ignition cycles while observing flame geometry. Electrical checks to the ignitor (voltage and current) help separate a true orifice restriction from a weak ignitor; if gas pressure and ignitor output are within expected ranges but symptoms persist, replace the orifice with the correct 316237805 assembly or the OEM-specified equivalent. After replacement, perform a leak-check at fittings, confirm flame stability across heat settings, and, when available, use a combustion analyzer to confirm acceptable combustion efficiency and safe CO levels.
Compatibility, Replacement Considerations, Installation Procedure and Troubleshooting Diagnostics
The 316237805 Frigidaire Ignitor Orifice Assembly combines a metering orifice with the ignition electrode interface to control gas delivery at the burner port and provide a reliable ignition source. Functionally, the orifice determines the volumetric flow for a given manifold pressure while the ignitor/electrode provides the high-voltage spark or ignition signal; both must match the appliance’s gas type (natural or LP), burner geometry, and the oven/range control’s electrical characteristics. When replacing this assembly, verify the appliance model cross‑reference, mounting orientation, and whether the OEM assembly is intended for spark ignition or a hot‑surface/continuous-electrode system - an incorrect orifice size or mismatched ignitor type will produce weak, yellow, or lifting flames and can lead to delayed ignition or excessive gas flow during start-up.
- Compatibility checklist: model number cross-reference, gas type (Natural vs LP), mounting hole spacing, and connector/electrode style.
- common symptoms: no ignition, repeated clicking with no flame, delayed ignition, yellow or unstable flame, or a persistent gas odor at start-up.
- Pre-install checks: confirm power and gas are shut off, verify replacement part orientation and gasket condition, and inspect the burner ports for obstructions.
Installation requires removal of the burner head to access the orifice assembly, careful transfer or replacement of any sealing gaskets, and secure mechanical mounting so the electrode position and orifice alignment replicate the original geometry; tightening should be to manufacturer torque recommendations where provided. For diagnostics, measure continuity or resistance of the ignitor against OEM specifications, verify the ignition control sends the expected voltage waveform during a call for heat, and observe flame characteristics instantly after replacement – a correct installation will produce stable blue cones at the port and consistent light‑off times. If ignition problems persist, isolate whether the fault is electrical (open electrode, control module fault, poor connector) or fuel‑delivery related (wrong orifice size, manifold pressure, or blocked port); pressure checks and leak testing should be performed with appropriate gauges and by qualified personnel when adjustable regulators or manifold pressures are suspected.
