316536623 Frigidaire Ignitor/Orifice assembly is a combined ignition and gas metering component used on Frigidaire gas cooking appliances; it pairs an ignitor element with a precisely sized orifice or jet to initiate and control combustion at a burner. as a discrete service part, the assembly locates at the burner port and integrates mechanical mounting, the gas orifice that determines flow rate, and the ignition element that produces the spark or hot surface required to ignite the fuel.The assembly is manufactured to withstand high temperatures and exposure to combustion by‑products and is specified to match the appliance’s fuel pressure and burner design.
Within the appliance the ignitor/orifice assembly directly interfaces with the gas delivery system (manifold, valve and regulator), the burner head, and the ignition control circuitry.The orifice determines the local fuel flow and, together with the burner geometry and air mixture, defines flame shape and BTU output; the ignitor provides the energy source for ignition and, depending on system design, may also be monitored by the control board or a flame-sensing device for safety interlocks. Proper seating, alignment and electrical connection are required to prevent delayed ignition, gas leakage, misfires or erratic flame behavior, and the assembly’s characteristics must match the appliance’s designed gas type and pressure to ensure correct combustion and compliance with safety margins.
In this article readers will find a technical description of how the 316536623 assembly functions, guidance on confirming compatibility with specific Frigidaire models, common symptoms of failure (such as no ignition, sustained clicking, weak or lifting flames, or gas odor), and step‑by‑step troubleshooting tests a technician can perform (visual inspection, continuity and voltage checks, and basic orifice verification). Replacement considerations are also covered, including matching orifice size and fuel type, proper mounting and sealing practices, and post‑replacement safety checks to verify correct ignition timing and flame characteristics. The focus is on practical diagnostics and safe,standards‑aware replacement rather than promotional data.

Functional Role and Performance Parameters of the Ignitor/Orifice Assembly
the 316536623 Frigidaire Ignitor/Orifice Assembly combines an ignition element with a precisely machined gas orifice to initiate and regulate combustion for a gas burner. The ignitor provides the electrical spark or hot surface energy to light the fuel-air mixture, while the orifice sets the volumetric fuel flow so the flame achieves the intended BTU output and shape. Prosperous operation depends on matching the ignitor type and its energy output with the orifice diameter and the applianceS supply pressure; mismatches will produce delayed ignition, unstable flames, or inadequate heat delivery rather than improving performance.
Performance parameters to evaluate include ignition response time, repeatability of spark or hot-surface heating, orifice diameter (expressed in thousandths of an inch or an OEM code), and compatibility with natural gas versus LP. Common practical checks for technicians are inspection for carbon or particulate blockage at the orifice, verification of correct orifice part for the gas type, and measurement of manifold pressure; verify manifold pressure before assuming the ignitor/orifice assembly is at fault. In service contexts, symptoms such as long ignition delay, yellow-tipped flames, or sputtering are indicative of either a restricted orifice, incorrect gas type, or inadequate ignitor energy rather than a single-component failure, so diagnosis should include both mechanical and fuel-delivery measurements.
- Ignition energy: spark voltage or hot-surface temperature affecting initial light-off
- Orifice sizing: small diameter limits flow and BTUs, larger diameter increases flame size
- Gas compatibility: distinct orifices for natural gas versus LP conversion
- Common failure modes: clogging, corrosion, incorrect orifice selection, or weakened ignitor output

How the 316536623 Frigidaire Ignitor/Orifice Assembly Operates Within the Appliance Gas Delivery System
The 316536623 Frigidaire Ignitor/Orifice assembly is a combined ignition and gas-meting component used to establish and regulate the burner flame in compatible Frigidaire gas ovens and ranges. The ignitor portion provides the thermal or spark energy necessary to ignite the fuel delivered thru the orifice; the orifice itself is a precision orifice that restricts gas flow to a rate specified by the appliance design. Together the two elements determine ignition timing, flame size and stability by matching the energy delivered for ignition with the correct volumetric flow of gas into the burner manifold. In practical service,replacement of the assembly restores the factory-set relationship between ignition energy and gas flow,avoiding mismatched flames that can cause incomplete combustion or cycling problems.
Functionally the assembly interfaces with the appliance gas valve, manifold and the electrical harness; compatibility considerations include the appliance’s fuel type (natural gas vs. LP), the orifice size required for the model and the connector style for the ignitor. Common operational failures include delayed ignition, a weak yellow flame, or the burner failing to light; these can result from a weak ignitor, a partially clogged orifice, incorrect orifice sizing, or wiring and valve control faults. Technicians typically verify operation by observing ignition sequence, checking continuity or current draw of the ignitor, and inspecting the orifice for deposits - replacing the assembly is recommended when the orifice is corroded or the ignitor does not meet its specified electrical or thermal behavior.
- Common symptoms: delayed ignition, weak flame, intermittent burner operation, or no ignition at all.
- Compatibility: verify natural vs.LP orifice and match electrical connector to the appliance harness.
- Service checks: inspect orifice for debris, measure ignitor continuity/current, confirm valve actuation timing.

Common Failure Modes and Diagnostic Symptoms of the Ignitor/Orifice Assembly
The 316536623 Frigidaire Ignitor/Orifice Assembly combines the resistive glow ignitor and the matched gas orifice into a single service component that controls initial flame establishment and primary gas metering in compatible Frigidaire ranges and ovens. Functionally, the ignitor must draw sufficient current and reach a specified temperature to allow the safety valve to open; concurrently the orifice size determines flow for the appliance’s design pressure and fuel type (natural gas or LP). In practice, technicians should verify that the replacement assembly matches the appliance’s model number and fuel configuration as an incorrect orifice will produce improper flame characteristics even if the ignitor itself is functioning correctly.
Common failure modes are manifested as electrical,thermal,or flow-related symptoms that are straightforward to isolate with basic tools: a multimeter to check continuity and resistance,an inspection of the orifice for deposits,and observation of flame color and ignition timing. Typical diagnostic signs include no glow or open-circuit ignitor readings, delayed ignition with repeated valve cycling, yellow or sooty flames indicating restricted orifice or incorrect fuel mixture, intermittent operation from corroded connectors, and, in some cases, a gas odor that requires immediate valve shutoff and leak testing. The following list summarizes the practical symptoms a technician will encounter during troubleshooting.
- No glow / open circuit: ignitor filament is broken or wiring has an open connection; multimeter shows infinite resistance.
- Weak or slow glow: degraded ignitor resistance leads to delayed valve operation and long ignition times.
- Delayed ignition or repeated cycling: orifice partially blocked or incorrect orifice size causes slow gas flow and intermittent lighting.
- Yellow, sooty flame or uneven burners: dirty orifice or incorrect fuel/pressure; indicates incomplete combustion.
- Intermittent operation: corroded terminals, loose harness, or thermal cycling faults in the assembly.
| Item | Description |
|---|---|
| Open circuit | Ignitor fails continuity; no heat generation and gas valve will not open. |
| Clogged orifice | Restricted flow produces delayed ignition, weak flame, or soot formation. |
| Connector corrosion | Intermittent resistance changes cause sporadic ignition or long glow cycles. |
Replacement Procedures, Installation Requirements and Model Compatibility for the Ignitor/Orifice Assembly
The 316536623 Frigidaire Ignitor/Orifice Assembly combines the ignition element and a precision gas orifice to control both the initiation of combustion and the metered fuel flow to the burner.Depending on the specific Frigidaire model, the ignition element may be a spark electrode or a hot surface style, so mechanical mounting, electrical connector type, and the orifice orientation must match the appliance’s design. As orifice diameter directly determines gas flow rate, verify model compatibility and fuel type (natural gas vs LP) before replacement to prevent improper mixture, regulator overload, or unsafe combustion characteristics.
Replacement requires shutting off gas and electrical power, confirming the assembly’s fit and orifice size, and using appropriate gas-rated thread sealant on fittings where specified. After installation,perform a pressure- and leak-check,then cycle the burner several times to observe ignition consistency and flame quality: a steady blue flame with a small,well-defined inner cone indicates acceptable fuel/air mixture while repeated delayed ignition,yellow tipping,or soot indicates incorrect orifice sizing,poor electrode gap/alignment,wiring faults,or manifold pressure issues. for conversions or intermittent faults, compare the installed orifice marking to the appliance conversion kit and inspect wiring and control module continuity before replacing additional components.
- Verify appliance model number and fuel type; match orifice diameter and connector geometry.
- Isolate gas and power, remove old assembly, and inspect mounting surfaces for damage.
- Use proper thread sealant where required and torque fittings to manufacturer torque ranges.
- Perform a leak test and observe multiple ignition cycles; note flame color and stability.
- If problems persist, check electrode gap, wiring, and manifold pressure before replacing controls.

Q&A
What is the 316536623 Frigidaire Ignitor/Orifice Assembly and what does it do?
The 316536623 is an OEM replacement assembly that combines the oven ignitor (hot surface or hot surface/glow type) with the gas orifice/nozzle used on certain Frigidaire ranges/ovens. The ignitor heats and produces the energy needed to allow the safety gas valve to open; the orifice meters the amount of gas delivered to the burner. Together they provide controlled ignition of the oven burner.
How do I know if this exact part is compatible with my oven model?
Always verify compatibility by matching your appliance model number to the part number in Frigidaire’s parts list or a trusted parts supplier. The same physical-looking assembly can have different orifices or mounting brackets for specific models or for natural gas vs LP conversions. If you cannot find the model lookup, take the old part number and your oven model number to a parts dealer or refer to the oven’s service manual before ordering.
What are the common symptoms that indicate the ignitor/orifice assembly has failed?
Typical failure symptoms include: the oven will not light (no flame), very long pre‑ignition delay, repeated clicking or trial-for-ignition cycles, weak or yellow flame (if it lights), and sometimes visible cracking or blackening of the ignitor element. Smelling gas without ignition is an emergency-shut off the gas and ventilate, then call a professional.
How can I test the ignitor to determine if it needs replacement?
Start with a visual inspection: a cracked, broken, or heavily blackened ignitor should be replaced. Use a multimeter to check for continuity; most hot‑surface ignitors show a cold resistance in the tens to low hundreds of ohms (values vary by model), while an open circuit indicates failure.A more definitive test is an amperage draw test while the oven attempts to ignite-an operating ignitor typically draws enough current to allow the gas valve to open (many hot surface types draw roughly 2.5-3.5 A at 120 V, but check OEM specs).If the ignitor glows but does not draw sufficient current to open the valve, replace it.
Can I replace the 316536623 myself? What are the safety steps and basic replacement steps?
Qualified DIYers can replace it, but because this involves gas and electrical connections you must follow safety precautions: turn off and isolate both the electrical supply (unplug or switch off breaker) and the gas supply before beginning. Basic steps: remove the oven access panel or burner box, disconnect electrical connectors to the ignitor, unthread the mounting screws, remove the old assembly, install the new assembly in the exact position, reconnect wiring, restore gas and power, and perform a leak test (soapy water) and ignition test. If you are unsure or uncomfortable with gas work,hire a licensed technician.
Do I need a different orifice if I convert my oven from natural gas to propane (LP)?
Yes. Orifices are sized for the specific fuel type.Propane requires a smaller orifice and often a regulator orifice change and/or pressure adjustment. The 316536623 assembly might potentially be configured for natural gas; if you plan to convert to LP you must use the correct LP orifice or an official conversion kit and follow the manufacturer’s conversion instructions or have a qualified technician perform the conversion.
How long does the ignitor/orifice assembly last and what causes premature failure?
Service life varies with usage but many ignitors last 5-15 years. Common causes of premature failure include power surges,repeated cycling from ignition problems (stress),physical damage,contamination (food spills,grease),and corrosion. Ensuring good ventilation, keeping the oven clean, and addressing slow ignition problems early can extend service life.
Is it better to buy the OEM 316536623 or an aftermarket replacement,and is there a warranty?
OEM parts are engineered to match the original specifications (mounting,electrical properties,orifice size) and are generally recommended to avoid fitment or performance issues. Quality aftermarket parts can be acceptable but verify that the orifice size and ignitor type match your oven and fuel type.Warranty terms vary by supplier; OEM parts from Frigidaire-authorized dealers commonly include a limited warranty-confirm warranty length and terms before purchase.
