316536623 Frigidaire Ignitor/Orifice Assembly is a combined ignition and gas metering component used on Frigidaire gas cooking appliances. The assembly typically integrates an ignitor element (either a spark or hot surface type) with a fixed orifice or jet that meters fuel to a specific burner port; it is a mechanical and electrical subassembly mounted at the burner that determines how and when gas is delivered and ignited.
Within the appliance, this assembly serves two primary functions: initiating combustion and controlling the local fuel flow to produce the intended flame size and heat output. It directly interfaces with the appliance’s gas valve and regulator, the burner head, and the ignition/control module or spark generator, and its performance affects flame stability, combustion efficiency, and safe shutoff behavior. Because the orifice size sets the fuel delivery for a given gas pressure, and the ignitor governs the timing and reliability of ignition, the part is vital both for correct thermal performance and for preventing unburned gas accumulation.
In this article readers will find a technical overview of how the 316536623 assembly functions, guidance on identifying compatible appliances and the meaning of orifice sizing, common failure symptoms to recognize (for example, no ignition, delayed ignition, weak or uneven flames, or continuous sparking), and systematic troubleshooting approaches a technician can use to isolate ignition versus fuel-delivery faults. The piece also covers practical replacement considerations-matching part numbers and orifice specifications, inspection of seals and mounting interfaces, and post‑replacement verification-framed with safety and diagnostic best practices suitable for technicians, engineers, and informed appliance owners.

Functional Role and Operational Requirements of the Ignitor/Orifice Assembly
The 316536623 Frigidaire Ignitor/Orifice Assembly is a combined ignition and fuel‑metering component used on compatible Frigidaire gas cooktops and ranges. In this assembly the ignitor (spark electrode) and the orifice are located in a fixed relationship so that a controlled gas jet is presented to the spark at the correct distance and angle; that spatial relationship is critical for consistent ignition.The ignitor generates the high‑voltage spark pulse while the orifice limits and shapes the gas flow from the manifold to produce a combustible mixture; both elements must be matched to the appliance’s gas type (natural or LP) and manifold pressure to ensure the correct flame size and heat output.
operational requirements for reliable performance include secure mechanical mounting, leak‑tight gas connections, proper electrode gap and alignment, and a clean, unobstructed orifice. Technicians diagnose faults by observing symptoms such as continuous clicking without flame, delayed ignition, weak or yellow flames, or audible gas leaks; remedial actions range from cleaning the orifice and re‑setting electrode position to replacing the entire assembly if the electrode is cracked or the orifice is eroded. Practical service steps include verifying that the replacement assembly matches the appliance’s specification, confirming electrical continuity to the ignitor circuit, and performing a controlled ignition test while monitoring flame pattern and stability.
- Common symptoms: repeated sparking with no ignition, weak/flashing flame, delayed light‑off.
- Rapid checks: visual electrode gap/alignment, orifice obstruction, continuity of ignitor wiring, and gas valve output at the manifold.
- When to replace: visible damage to the electrode, persistent clogging after cleaning, or mismatch of gas type.

How the 316536623 Frigidaire Ignitor/Orifice Assembly integrates with Burner Control and Gas Delivery
The 316536623 Frigidaire Ignitor/Orifice Assembly is a combined ignition and gas‑metering component that interfaces directly with the appliance control circuitry and the gas manifold. Mechanically it seats between the manifold/gas valve and the burner head so the orifice produces a calibrated jet while the ignitor provides the energy required to establish combustion. Electrically the ignitor is part of the ignition circuit: the control board or ignition module supplies power and monitors the ignitor or flame signal,and the gas valve will onyl open when the ignition circuit indicates the correct pre‑ignition condition. This assembly therefore performs both metering and safety functions, and replacement must match the original orifice size and ignition characteristics to maintain designed air/fuel ratio and valve timing.
In operation,the control board issues an ignition command and the ignitor either heats to the specified temperature or generates a spark; once the ignition condition is satisfied the gas valve supplies fuel through the orifice to the burner head. Practical compatibility issues include using the correct orifice for the gas type (natural vs LP), matching the ignitor’s electrical characteristics and mounting orientation to the appliance, and ensuring the flame‑sensing pathway (if present) is intact. Technicians commonly trace problems to a faulty ignitor when the valve refuses to open,to an incorrect orifice when flame quality is poor (yellow,sooting,or too large/small),or to wiring/connectors between the control board and assembly when intermittent operation occurs.
- Signal path: control board → ignitor/ignition module → gas valve; flame feedback returns to controller.
- Safety interlock: ignitor condition or flame sense required before valve energizes.
- Metering: orifice size determines volumetric flow at given manifold pressure.
- Compatibility checks: verify gas type, mounting, and electrical connector pinout.
| Item | Description |

| Ignitor | Provides ignition energy (hot surface or spark) and can participate in safety interlock/flame sensing. |
| replacement check | Confirm orifice size, ignitor electrical characteristics, connector type, and appliance model compatibility. |
Diagnostic Indicators and Common Failure Symptoms of the Ignitor/Orifice Assembly
The 316536623 Frigidaire Ignitor/Orifice assembly is a combined ignition and gas-metering module used on compatible Frigidaire gas ranges and ovens. The ignitor element provides the thermal or ionization stimulus to permit gas flow and establish a stable flame, while the orifice precisely meters gas flow to the burner for correct flame geometry and heat output. Because the assembly couples an electrical heating element and a sized orifice, failures can be electrical (open circuit, reduced heating), mechanical (clogged orifice, damaged seating), or interface-related (wiring, connector or valve drive). Confirming compatibility requires matching the oven model number to the parts list; the assembly will function only when the orifice size and ignitor characteristics match the appliance’s gas type and control strategy.
Common diagnostic indicators are delayed or absent ignition, a persistent weak or yellow flame, soot accumulation, or frequent control lockouts and cycling. Practical troubleshooting begins with a visual and electrical check: inspect the ignitor for cracks or breakage, verify continuity and resistance against the manufacturer’s specification, and observe whether the ignitor reaches a visible glow during the ignition sequence. A useful rule: if the ignitor glows but the burner does not light, suspect gas flow or valve control; if voltage is present at the connector but the ignitor does not glow, replace the ignitor assembly. Check the orifice for carbon deposits or physical restriction when low flame or poor combustion is present, and always isolate power and shut off gas before disassembly or replacement.
- Failure to ignite or long ignition delays
- weak, lifting, or yellow-tipped flame indicative of poor gas metering or incomplete combustion
- Visible soot or carbon buildup on burner head
- Intermittent ignition or cycling of the burner control
- No glowing element despite applied voltage at the connector
| Item | Description |
|---|---|
| Delayed ignition | Commonly caused by a weak ignitor that heats slowly or a partially obstructed orifice reducing gas flow. |
| No glow, voltage present | Indicates ignitor element failure; replace the ignitor/orifice assembly or test wiring and connector for intermittent contact. |
| Yellow flame or soot | Suggests incorrect air/gas mixture or a clogged orifice; clean or replace the orifice and verify correct orifice sizing for the appliance gas type. |
Troubleshooting Procedures,Replacement Considerations,and Installation Best Practices for the Ignitor/Orifice Assembly
The 316536623 Frigidaire Ignitor/Orifice Assembly combines the ignition element and a matched gas orifice to initiate and regulate burner combustion in compatible Frigidaire ranges. The ignitor provides the electrical heating and timing signal required by the gas valve; when its temperature and current draw reach the designed threshold the valve opens and gas is released through the orifice. Orifice size and geometry determine fuel flow for a given manifold pressure, so correct orifice selection (natural vs. LP) and seating are essential for stable flame shape and complete combustion.Technician inspections should consider ignitor heating time, steady-state current draw, visual flame quality, and whether the assembly matches the appliance model’s service specifications before approving reuse or replacement.
Troubleshooting begins with measured electrical and visual checks: measure ignitor resistance and running current against the service manual values, confirm the ignitor reaches proper glow in the expected timeframe, and observe whether the flame establishes promptly and remains steady. Replacement considerations include verifying the orifice size, thread and sealing method for the manifold connection, and ensuring the replacement assembly is listed for the appliance model and gas type; mismatched orifices can cause high CO, weak flames, or frequent valve cycling. Installation best practices include torquing fasteners to manufacturer specs, orienting the ignitor to prevent contact with burner components, performing a pressure and leak test after assembly, and re-checking flame characteristics and safety interlocks before returning the range to service.
- Common symptoms to check: delayed ignition,yellow or lifting flame,repeated valve cycling,and visible damage or cracking of the ignitor element.

| Mounting | Proper screw torque, alignment, and gasket/seal type to prevent gas leaks and ensure correct burner spacing. |
Q&A
What is the Frigidaire 316536623 Ignitor/Orifice Assembly and what does it do?
The 316536623 is a combined ignitor and burner orifice assembly used on gas ranges and ovens. The ignitor provides the heat or spark to ignite the gas, and the orifice is the small jet that meters gas flow to the burner. Together they control ignition and initial flame characteristics for one burner or oven burner tube.
How do I know if this part is compatible with my appliance?
this assembly fits a range of Frigidaire (and some associated brand) gas ovens and ranges, but compatibility varies by model and production year. The correct way to confirm fitment is to check yoru appliance model number against the part listing from Frigidaire or an authorized parts dealer, or to compare the existing assembly visually and by mounting/connector type. if in doubt, provide the exact model number to the parts supplier or technician.
What are common symptoms that the ignitor/orifice assembly is failing?
Common symptoms include: the oven or burner will not light, long ignition delays, weak or intermittent flame, continuous clicking without ignition, or visible damage/burn marks on the ignitor.Smelling gas before ignition is a serious symptom – stop using the appliance, turn off the gas and power, ventilate the area, and call a technician instantly.
How can a technician test whether the ignitor or orifice is bad?
A technician will first visually inspect the ignitor for cracks or burns. They can test the ignitor for electrical continuity with a multimeter (a failed ignitor usually shows an open circuit). More functional testing involves observing whether the ignitor glows when the oven calls for gas; if it does not glow,it is likely faulty. Orifice problems are usually diagnosed by observing flame size and shape; a clogged orifice will cause small or irregular flames. Never test live gas components without proper safety precautions.
Can I replace just the ignitor, or do I have to replace the whole assembly?
Sometiems the ignitor can be replaced separately if the orifice and mounting hardware are intact and compatible. However, many owners and technicians prefer replacing the combined ignitor/orifice assembly to ensure correct alignment, orifice sizing and to avoid fitment issues. Always verify whether your appliance uses a combined assembly or separate components before ordering parts.
What tools and safety steps are required to replace this assembly?
Tools commonly needed: screwdrivers or nut drivers, an adjustable wrench, a multimeter for tests, and a soap solution or leak detector spray for gas checks. Safety steps: disconnect electrical power, shut off the gas supply, work in a well-ventilated area, and do not smell-test for leaks with your nose.After installation, restore gas and use a soapy solution or approved leak detector at connections to check for leaks.If you are not comfortable working on gas appliances,hire a qualified technician.
After replacing the part, the oven still won’t ignite properly – what should I check next?
Check that the new assembly is installed correctly and that electrical connectors are tight. Verify the orifice is the correct size for your fuel type (natural gas vs. LP/propane) – wrong orifice can cause poor combustion. confirm the ignitor receives power when the burner is commanded (use a multimeter),ensure gas supply and shutoff valve are open,and inspect the gas regulator,safety valve,and wiring. If everything appears correct but the problem persists, contact a qualified service technician.
How long does this part typically last and where should I buy a replacement?
Service life varies with usage and conditions; many ignitors last several years but can fail sooner due to thermal stress or electrical issues. buy replacements from Frigidaire-authorized dealers,reputable appliance parts suppliers,or directly from the manufacturer to ensure OEM quality. Keep your appliance model number handy when ordering to avoid incorrect parts.
