316237805 Frigidaire Ignitor Orifice Assembly is a factory-designated replacement component that combines the ignition element and the gas orifice/nozzle assembly used on certain Frigidaire gas cooking appliances. it is a mechanical and electro-thermal subassembly designed to position the ignitor relative to the burner ports while providing a controlled metering point for gas flow; in many appliance designs this assembly ensures correct flame initiation and repeatable combustion at a specific burner location.
Within the appliance the ignitor orifice assembly interfaces directly with the gas manifold and the burner head, and it effectively works in concert with the gas valve, ignition control circuit, and any flame-sensing or safety devices. the ignitor provides the required energy for flame initiation (either as a hot-surface ignitor or spark source depending on design) while the orifice defines the local gas jet size and flow characteristics; together they affect ignition timing, flame pattern, and combustion stability. Proper alignment, sealing, and orifice sizing are crucial to maintain intended heat output and to avoid issues such as delayed ignition, incomplete combustion, or gas leakage that could trigger safety interlocks.
This article will describe the functional role of the 316237805 assembly, highlight common appliance models and installation locations where it is used, and outline compatibility considerations (OEM versus aftermarket and orifice sizing).It will also summarize typical failure symptoms and diagnostic cues a technician or informed owner can use to isolate ignitor- or orifice-related problems, present high-level troubleshooting approaches, and cover practical replacement considerations such as gasket condition, mounting orientation, sealing and leak testing, and when professional service is recommended for safe and code-compliant repair.

Function and role of the ignitor orifice assembly in Frigidaire gas appliance operation
The 316237805 Frigidaire Ignitor Orifice Assembly is a combined metering and mounting component that establishes the gas flow rate to the main burner while positioning the ignitor relative to the burner port. The orifice element controls volumetric flow for a given manifold pressure so the ignitor lights a stable, correctly sized flame; incorrect orifice size, debris, or improper orientation changes flame shape and heat output and can cause delayed ignition or valve cycling. This assembly is designed to match Frigidaire manifold fittings and ignition systems, so technicians should verify the part number and manifold pressure specifications before replacement rather than substituting a diffrent orifice size or generic fitting.
In operation the assembly behaves as a passive flow limiter that must be coordinated with the appliance’s ignition sequence and manifold valve characteristics. Practical diagnostics include measuring flame pattern (sharp blue cone vs. yellow or lifting flame), observing ignition delay, and checking for soot or gas odor that indicate under- or over-fueling; swapping to the correct 316237805 assembly or the appropriate LP conversion orifice typically resolves those issues. Installation best practices are to inspect and clear the burner tube and orifice seat of debris, torque the fasteners to avoid gas leaks, and confirm compatibility with the oven’s ignitor type and manifold pressure to ensure consistent combustion and safe operation.
- Function: meters gas flow and positions the ignitor for reliable ignition.
- Common symptoms of failure: delayed ignition, sooting, weak flame, or valve cycling.
- Compatibility: match part number and fuel type (natural vs LP) to manifold pressure.
- Service notes: inspect for blockages, gaskets, and correct mounting orientation during replacement.

How the 316237805 frigidaire Ignitor Orifice Assembly works inside Frigidaire gas ranges and refrigerators
The 316237805 Frigidaire Ignitor Orifice Assembly combines the gas metering orifice and the ignitor mounting point into a single serviceable component. Gas from the control valve passes through a precisely sized aperture that establishes the downstream pressure and volumetric flow; the ignitor (spark electrode or hot surface element) is located immediately adjacent to the orifice so ignition occurs at the correct mixture and location. The assembly’s geometry and orifice diameter determine flame size, stability, and the timing required for the ignition sequence, and it must align with the burner ports and valve outlet to ensure consistent combustion and reliable operation.
Technically, failures manifest as restricted flow, delayed ignition, continuous sparking, or a weak/sooty flame; these symptoms often point to a clogged orifice, damaged electrode insulation, or mismatched orifice size. Compatibility depends on thread form, sealing method and the OEM-calibrated aperture, so replacements should match the original 316237805 specification or an approved cross-reference to avoid altered combustion characteristics.For service,inspect the orifice for carbon or debris,verify electrode positioning and insulation integrity,and confirm that the replacement part matches the valve interface and orifice rating before reassembly.

Common failure symptoms, measurable performance indicators, and when to suspect orifice/ignitor faults
The 316237805 Frigidaire Ignitor Orifice Assembly integrates a precisely sized orifice that meters gas flow and an ignitor element that provides the energy needed to initiate combustion. In practical systems the ignitor either produces a high-voltage spark or heats to a glowing temperature, and the orifice determines the fuel/air ratio delivered to the burner port; both functions must match the appliance’s manifold pressure and burner geometry for reliable operation. Technicians should view this assembly as a paired hydraulic/electrical component: a blocked orifice or incorrect orifice sizing will produce fuel-flow symptoms even when the ignitor is functioning, while a failed ignitor, wiring fault, or ignition module issue will present electrical symptoms despite an unobstructed orifice.
Common,measurable indicators that point to orifice or ignitor faults include ignition delay,intermittent lighting,abnormal flame shape or color,and electrical test results. If the ignitor shows open circuit or abnormally high resistance on a multimeter, or if there is no voltage present at the ignitor terminal during an ignition cycle, suspect an ignitor or wiring/ignition-module failure; if the ignitor is producing a spark or glow but the burner fails to sustain a flame, check for orifice blockage, incorrect orifice size, low manifold pressure, or restricted gas lines. For troubleshooting, record ignition time, measure ignitor resistance and applied voltage, inspect flame appearance (sooting or yellowing), and compare observed values to the appliance service specifications to determine whether to replace the 316237805 Frigidaire Ignitor Orifice Assembly or address upstream gas/electrical issues.
- Delayed ignition or long ignition time (multiple seconds) – could be ignitor weak or reduced gas flow.
- Intermittent lighting or clicking with no flame – suspect ignitor/wiring or spark-generator faults.
- Weak, yellow, or sooting flame despite a glowing/sparking ignitor – indicates orifice restriction, wrong orifice, or pressure issues.
- No continuity or abnormal resistance on the ignitor element - electrical failure of ignitor.
| Item | description |
|---|---|
| Ignitor continuity | Measure ohms across element; open or very high resistance indicates ignitor failure. |
| Applied ignition voltage | Verify correct voltage present during cycle; absence points to wiring or ignition module faults. |
| Ignition time | Time from command to flame; extended times suggest weak ignitor or restricted gas flow. |
| Flame appearance | Blue, stable flame vs yellow/sooting flame helps differentiate fuel flow/orifice issues from ignition energy problems. |
Compatibility matrix, replacement considerations, installation steps and post‑install diagnostic checks
The 316237805 Frigidaire Ignitor orifice Assembly combines the ignition element and the gas metering orifice into a single serviceable component that controls both spark/hot-surface initiation and the initial gas flow to the burner. Functionally, the orifice diameter determines gas flow rate and pressure drop while the ignitor provides the energy source to achieve flame establishment; mismatches in orifice size, mounting orientation, or electrical connector type will change flame geometry and ignition timing. Confirm compatibility by matching the appliance model number and OEM cross-reference, verifying whether the unit is configured for natural gas or liquid propane (LP), and checking that the assembly’s mounting footprint and connector pinout align with the range’s manifold and wiring harness.
Installers should follow standard safety procedures: isolate gas and power, remove the old assembly, inspect and replace any degraded gaskets or manifold fittings, and torque fasteners to the manufacturer’s specification before re‑energizing. Perform post‑install diagnostics to validate fit and operation: confirm there are no gas leaks at the orifice/manifold interface, verify correct ignition sequence and flame characteristics (stable flame without lift or yellow tipping), and measure ignitor resistance/current and supply voltage to ensure the ignition circuit operates within expected ranges. The checklist below summarizes key verification points technicians typically perform after replacement.
- Confirm part-to-model match and gas type (NG vs LP).
- Inspect and replace sealing gaskets; torque fasteners per spec.
- Perform a soap/leak-test at manifold and orifice connections.
- Verify ignitor electrical continuity, resistance, and supply voltage.
- Observe flame color, size, and stability during several ignition cycles.
