316536610 Frigidaire Ignitor/Orifice Assembly is an integrated ignition and gas metering component used in Frigidaire gas ranges and ovens. The assembly combines an ignitor element (either a hot surface or spark-type ignitor depending on the specific model) with a precision orifice that meters gas flow to a burner. As a discrete replaceable part, it is a mechanical and electrical interface between the appliance’s fuel delivery system and its ignition circuit.
Inside the appliance the ignitor/orifice assembly performs two primary functions: it provides the energy source required to ignite the gas, and it controls the rate of gas delivered to the burner through a fixed orifice size. The component interfaces directly with the burner head,the gas manifold and valve,and the appliance control/ignition module or switch wiring. It also works in conjunction with safety features such as flame sensing circuits and pressure regulation on the manifold to ensure reliable and safe ignition and combustion.
In this article you will find a technical overview of the 316536610 assembly covering how it functions, how to determine compatibility with specific Frigidaire models, common failure symptoms (for example no ignition, delayed ignition, weak or yellow flame, or gas odor), and a structured approach to troubleshooting (electrical checks, visual inspection for clogging or damage, and interface verification with the gas valve and control board). The article will also discuss replacement considerations including correct orifice sizing for natural gas versus LP conversions, proper mechanical fit and electrical connectors, and safety and code-related checks to observe when installing and testing the replacement part.

Function and Role of the frigidaire Ignitor/Orifice Assembly in Gas Burner Operation
The 316536610 Frigidaire Ignitor/Orifice Assembly is a combined ignition and gas metering component used on specific frigidaire gas burners. The ignitor portion produces the spark (or hot surface heat in some oven applications) to initiate combustion while the orifice controls the volumetric flow of fuel leaving the manifold to the burner head; together they determine ignition reliability and flame characteristics. Proper operation requires matching the orifice diameter to the appliance’s gas type (natural gas vs. LP) and the correct electrode gap and orientation so the spark reliably crosses the combustion air/fuel stream at the burner port.
Typical failure modes include delayed ignition with audible clicking, sustained clicking without lighting, weak or lifting flames, or a persistent smell of gas if the ignitor fails to light the gas quickly. Technicians should inspect for clogged orifices, corroded electrodes, broken ceramic insulators, and incorrect part substitution.Basic diagnostic steps include a visual inspection, checking electrode gap (~1.5-3 mm), verifying continuity of the ignitor circuit with a multimeter, confirming orifice marking for correct gas type, and performing a post-installation gas-leak and flame-shape check after replacing the assembly. Installation requires correct seating, gasket use, and appropriate torque on fittings to avoid distortion of the orifice or damage to the electrode.
- Primary functions: ignition initiation and gas metering at the burner.
- Common diagnostics: spark observation, continuity/resistance check, orifice inspection for debris.
- Installation considerations: verify part/model compatibility, gas type, electrode gap, and leak test.
- Symptoms of failure: delayed ignition, continuous sparking, weak/yellow flame.

How the 316536610 Frigidaire Ignitor/Orifice Assembly Works Inside the Appliance
The 316536610 Frigidaire Ignitor/Orifice Assembly combines a hot-surface ignitor element with a precision gas orifice into a single serviceable unit that mounts at the burner manifold.In operation the appliance control module applies voltage to the ignitor so the ceramic element heats and begins to conduct; when the ignitor reaches its operating temperature it allows sufficient current flow for the gas valve to open and release fuel through the matched orifice. The orifice portion meters the gas flow and shapes the fuel/air mixture so the flame geometry and heat delivery match the oven’s design, which is why the correct part number and orientation are critical for safe, consistent combustion and proper temperature control.
- features: integrated ignitor plus metered orifice for correct flame sizing and simplified replacement.
- Common symptoms of failure: long glow time before ignition, no flame despite glowing element, yellow or sooty flame indicating orifice or mixture issues.
- compatibility notes: must match manifold mounting, connector type, and orifice size specified for the model to maintain OEM performance.
Technicians typically verify operation by observing ignitor glow profile and measuring circuit continuity/voltage at the connector, then inspecting the orifice for clogging or deformation; replacement with the 316536610 assembly restores both the heat source and the gas metering geometry in one service step. After installation, confirm proper electrical connections, check for gas leaks at the seal, and verify stable flame and expected heat-up times during a controlled test cycle.When troubleshooting, distinguish an electrical ignitor fault (open circuit, no glow or intermittent glow) from an orifice-related combustion issue (unstable flame, sooting), because repair actions differ: electrical diagnostics and connector replacement for ignitors versus cleaning or correct-orifice replacement for flow problems.

Common Failure symptoms and Diagnostic Indicators of Ignitor/Orifice Malfunction
The 316536610 Frigidaire Ignitor/orifice Assembly houses two tightly coupled functions: the ignitor that produces the initial energy to light the fuel and the orifice that meters gas flow into the burner. In practice, the ignitor might potentially be a spark-type or a hot-surface element depending on model, and the orifice is sized to match manifold pressure and burner characteristics; using the correct assembly for a given Frigidaire model maintains the intended air-fuel ratio and stable combustion. Technicians should verify physical compatibility (mounting, connector type, and orifice size) before replacement, and inspect the assembly for carbon buildup, corrosion, or damaged insulation that can alter ignition timing or flow characteristics.
- Delayed ignition or repeated clicking before a steady flame
- Intermittent or weak flame,yellow tipping,or soot deposits
- No ignition while gas is present (detectable odor or hissing)
- Frequent burner shutdowns or inconsistent heat output across cycles
| Item | Description |
|---|---|
| Delayed ignition | Often caused by weak spark/glowing ignitor or partially obstructed orifice; verify ignitor output and inspect orifice for deposits |
| Yellow or lifting flame | Indicates rich mixture from oversized orifice,or air shutter/purge issues; compare flame pattern to factory reference |
| No ignition with gas present | Could be failed ignitor,faulty wiring/connector,or safety interlock; check for continuity,voltage at the ignitor connector,and proper valve actuation |
Diagnostic steps should combine visual inspection,basic electrical checks,and operational observation: look for cracked ignitor ceramics or frayed leads,measure continuity and supply voltage to the ignitor during a startup cycle,and observe flame shape and stability instantly after ignition. Practical examples: a burner that produces a loud pop then lights usually signals delayed ignition from weak spark or partial blockage in the orifice, whereas a continuously yellow flame after ignition suggests incorrect orifice size or restricted primary air; correcting the issue requires matching the assembly and verifying manifold pressure and air inlet conditions rather then replacing parts by guesswork.
Compatibility, Replacement considerations, and Installation Procedures for the 316536610 Frigidaire Ignitor/Orifice assembly
the 316536610 Frigidaire Ignitor/Orifice assembly combines the gas metering orifice and the ignition element into a single serviceable unit that controls fuel flow and initiates combustion in compatible Frigidaire gas ranges and ovens. the orifice determines the maximum gas flow and must match the appliance’s design and fuel type (natural gas or LP) to achieve correct flame characteristics; the ignitor provides the high-temperature element or spark necessary to light the gas. Functionally, failures of either subcomponent produce distinct symptoms: a blocked or mismatched orifice causes low or uneven flames and poor heat output, while a degraded ignitor causes delayed ignition, repeated sparking, or no ignition at all. Technicians should verify appliance model numbers and fuel type before assuming interchangeability, as physical fittings, thread types, and electrical connector styles vary across production years and models.
Replace the assembly only after confirming the correct part and preparing the appliance for safe service. disconnect power and gas supply, depressurize the gas line, and ventilate the area before removing the old unit. Typical installation steps include removing the burner housing, gently unthreading the existing orifice, verifying and replacing any gaskets, installing the new assembly with a gas-rated thread sealant if required by manufacturer instructions, reconnecting electrical leads, and performing an initial functional and leak test at low pressure. Practical items to check after installation are steady flame shape, consistent ignition timing, absence of gas smell, and no audible leaks; bench-testing the ignitor for expected resistance or spark behavior before assembly can save time during field service.
- Verify model and fuel type against manufacturer parts data before ordering the replacement.
- Use only gas-rated sealants or tapes specified by the appliance manufacturer.
- Check electrical connectors for corrosion and secure mechanical mounting to avoid misalignment.
- Perform a soap or electronic gas-leak test and confirm correct flame pattern during first heat cycle.

Q&A
What is the Frigidaire 316536610 Ignitor/orifice Assembly and what does it do?
The 316536610 Ignitor/Orifice assembly is a gas appliance service part used on certain Frigidaire gas ranges/ovens. it combines the gas orifice (which meters fuel flow) and the ignitor (which lights the gas). Together the components ensure the burner or oven pilot receives the correct amount of gas and a reliable ignition source for safe operation.
how do I know if the 316536610 assembly is the right replacement for my appliance?
Confirm compatibility by checking your appliance model number (usually on a sticker behind the oven door, on the frame, or on the back of the range) and cross-referencing it with the part listing from Frigidaire or an authorized parts dealer. Do not rely on visual similarity alone-OEM part numbers ensure proper fit, gas orifice size, and mounting orientation.
What are common symptoms that indicate the ignitor/orifice assembly is failing?
Common signs include: the oven or burner will not light, slow or incomplete ignition, unusually long preheat times, weak or uneven flame, repeated clicking or continuous sparking, and smelling gas without ignition. If you see a cracked ignitor,corrosion,or a clogged orifice,replacement is usually required.
Can I clean or repair the orifice instead of replacing the whole 316536610 assembly?
minor clogs in the orifice can sometimes be cleared with careful cleaning using compressed air or approved orifice-cleaning tools. Though, as the assembly integrates the ignitor and orifice and ignition components can be fragile or degraded, technicians frequently enough recommend replacing the entire assembly to restore reliable performance and ensure correct gas metering.
Is this a challenging part to install and can I replace it myself?
Installation difficulty varies by model. Basic mechanical skills and the right tools may allow a competent DIYer to replace the part, but it requires shutting off power and gas, proper reassembly, and a leak test on gas fittings. Because gas work involves safety risks (gas leaks, improper ignition), manufacturers and safety codes recommend using a qualified appliance technician unless you are experienced with gas appliance repairs.
Are there any safety precautions I should follow when handling or installing the 316536610 assembly?
yes.Always turn off electrical power and the gas supply before beginning work. Avoid touching the ignitor element with bare hands (oils can damage it). After installation, perform a gas leak test with soapy water or a gas leak detector on all fittings and confirm proper ignition and flame characteristics. If you smell gas at any time, stop and ventilate the area, do not operate electrical switches, and contact your gas supplier or a technician.
How can a technician test whether the ignitor portion of the assembly is bad?
A technician will visually inspect for damage and then test electrical continuity and current draw. A hot surface ignitor typically shows continuity; more critically important is that it draws the correct current when powered-if it fails to draw sufficient current it won’t open the gas valve. Technicians may use a clamp meter to measure amp draw or a multimeter for resistance checks, and will also observe ignition timing and flame behavior during a functional test.
Can using the wrong orifice size cause problems, and should orifice size ever be changed?
Yes. Orifice size determines gas flow and proper combustion for the burner or oven. using an incorrect orifice can cause weak flames, soot, incomplete combustion, higher carbon monoxide risk, or overheating. Orifice changes should only be done for specific conversions (such as, changing fuel types) and must follow manufacturer specifications and local codes-performed by a qualified technician.
