316536610 Frigidaire Ignitor/Orifice Assembly is a combined ignition and gas-metering component designed for use in gas cooking appliances. The assembly integrates an ignitor element with a precisely sized orifice to control fuel flow to a specific burner or burner cluster; as a replaceable module it is identified by the Frigidaire part number 316536610 for compatibility with specified ranges and ovens.
Within the appliance, the ignitor/orifice assembly serves two primary functions: initiating combustion and regulating the volume of gas delivered to the burner. It interfaces directly with the burner manifold and gas valve, and it is monitored by the appliance control circuitry and any flame-sensing or safety interlock systems. Correct operation of the assembly affects ignition timing, flame stability and combustion quality, and any degradation or mismatch in orifice size or ignitor performance can lead to delayed lighting, incomplete combustion, or safety interlocks preventing burner operation.
In this article readers will find a technical overview of the assembly’s function and design considerations, guidance on model compatibility and how to confirm the correct part for a given appliance, common failure symptoms to look for (such as failure to ignite, slow ignition, weak or uneven flame, or fault codes), and the logical steps for troubleshooting and assessing whether replacement is required. The discussion will also cover practical replacement considerations-correct orifice sizing for fuel type, electrical and mechanical connection points, safety precautions and why following manufacturer specifications matters-so that a technician, engineer, or informed appliance owner can make sound diagnostic and service decisions.

Functional Role and Operational Requirements of the Ignitor/Orifice Assembly
The 316536610 Frigidaire Ignitor/Orifice Assembly integrates the ignition source and the gas metering orifice into a single serviceable component that controls both flame initiation and fuel flow in compatible Frigidaire gas ranges and ovens. The ignitor provides the energy required to create a spark or reach a hot surface temperature for ignition, while the orifice physically restricts gas flow to establish the intended BTU delivery and flame shape. Proper operation depends on matching the assembly’s ignition type (spark vs. hot surface), connector and mounting geometry, and orifice sizing to the appliance model and fuel type (natural gas or propane) to ensure consistent timing, complete combustion, and safe shutoff behavior in response to control inputs and safety interlocks.
Operational requirements for reliable performance include a correct electrical supply and grounding for the ignitor circuit, leak-tight mechanical mating to the burner manifold, and an orifice sized for the appliance’s regulator pressure and fuel. Contamination, misalignment, or an incorrect orifice will produce delayed ignition, unstable or yellow flames, or incomplete combustion; conversely, an ignitor with excessive resistance or an intermittent connection can cause repeated sparking or failure to light. Technicians performing replacements should verify fuel type and manifold pressure, use the specified orifice jet for conversions, and confirm that connector pins and mounting surfaces are secure and free of debris before returning the unit to service.
- Symptoms of improper operation: delayed ignition, continuous sparking, weak or yellow flame, or no ignition.
- Key service checks: verify electrical continuity and voltage to the ignitor, inspect orifice size and fit, and test for gas leaks at the assembly seal.
- Compatibility concerns: confirm ignition type and model fitment; replace orifice jets for fuel-type conversions.
| Item | Description |
|---|---|
| Ignitor | Generates ignition energy (spark or hot surface); requires correct voltage, continuity, and secure connector. |
| Orifice | Restricts gas flow to set BTU and flame characteristics; must match fuel type and manifold pressure. |
| Mounting/Seals | Ensures alignment to burner and a leak-tight connection to the manifold to prevent combustion issues. |
How the 316536610 Frigidaire Ignitor/orifice assembly Interfaces with Burner, Gas Flow, and Control Electronics
The 316536610 Frigidaire ignitor/Orifice Assembly combines the spark (or hot‑surface) ignition element and the gas orifice into a single mounting that interfaces directly with the burner manifold and the appliance’s control electronics. Mechanically, the orifice threads into the gas manifold outlet and meters fuel flow to the burner ports; the ignitor is positioned and insulated to create a reliable ignition source at the burner face. Electrically,the ignitor connects to the range’s spark module or hot‑surface circuit via insulated leads and a chassis ground; the control electronics sequence the ignition by providing high‑voltage pulses (spark systems) or controlled current to a glow element (hot‑surface systems) while simultaneously opening the gas valve so fuel arrives only when ignition energy is present.
Behavioral compatibility depends on orifice sizing, gas type, and electrical interface: the orifice diameter must match either natural gas or LP specifications and the thread/seat geometry must match the manifold, while the ignitor’s connector, lead routing, and required operating voltage must match the control module. Practical faults include a clogged orifice producing a low, yellow, or fluttering flame; an electrode that is misaligned, cracked, or shorted causing intermittent or continuous sparking; and mismatched orifice size causing over‑ or under‑firing. Technicians typically verify correct interface by confirming secure mechanical fit, checking continuity and insulation of the ignition lead, observing spark position and flame characteristics, and verifying the appliance control supplies the expected ignition signal before replacing the assembly.
- Typical checks: spark presence/position, flame color/height, orifice cleanliness and size, lead continuity, and manifold sealing.
- Common symptoms of interface failure: delayed ignition, continuous sparking, weak flame, or gas odor at rest.
- Replacement guidance: match gas type, orifice size, thread form, and electrical connector style to the original part.
| Item | Description |
|---|---|
| ignitor | Provides ignition energy (spark electrode or hot‑surface element) and interfaces electrically with the control module. |
| Orifice | Precision orifice that meters fuel flow to the burner ports; size must match gas type and manifold pressure. |
| Control Interface | Electrical connection to the spark module or oven/range control that sequences ignition and verifies combustion where applicable. |
Diagnostic Indicators and Common Failure Symptoms of the Ignitor/Orifice Assembly
The 316536610 Frigidaire Ignitor/Orifice Assembly combines the ignition element and the metering orifice that together initiate and regulate combustion at the oven burner. The ignitor provides either a hot-surface heat source or a spark to actuate the gas valve and establish a stable flame, while the orifice determines the gas flow rate and primary air mixture for correct flame shape and temperature. Functionally, both pieces must match the oven’s manifold pressure, gas type (natural or LP), mounting geometry, and electrical connector; an otherwise correct-looking replacement can still produce poor combustion if the orifice size or ignitor draw does not conform to the original specification.
Technically, failures fall into electrical, thermal, and mechanical categories and are diagnosed with basic observation and measurements. Use a multimeter to check ignitor continuity and current draw against OEM service limits, observe warm-up (glow) time and flame characteristics during ignition, and inspect the orifice for restriction or deformation. Common, practical indicators include the oven failing to light or requiring multiple ignition attempts, a long pre-ignition glow period before gas flows, yellow or lifting flame and soot (indicative of poor air-fuel ratio), intermittent operation, and visible cracks or carbon buildup on the ignitor. Below are the typical symptoms technicians check and a concise reference for speedy tests.
- No ignition / extended glow: ignitor glows but burner never lights - frequently enough an ignitor that does not reach required temperature or draws insufficient current to open the safety valve.
- Delayed or intermittent ignition: Sporadic lighting or long ignition delays-can indicate weakened ignitor life, intermittent electrical connections, or partial orifice blockage.
- Poor flame quality or soot: Yellow, lifting flame or black deposits – suggests incorrect orifice sizing, clogged orifice ports, or improper primary air mixture.
- Continuous sparking or valve chatter: Persistent electrode spark or gas flow cycling – electrical fault at ignitor or control,or pressure/valve inconsistency.
- Visible damage: Cracked ceramic, glazing, or heavy carbon on the ignitor or deformity in the orifice – typically requires replacement rather than cleaning.
| Item | Description |
|---|---|
| Resistance/continuity | Ignitor should show continuity and fall within the manufacturer’s resistance/current draw range; an open circuit or abnormally high resistance indicates failure. |
| Warm‑up (Glow) Time | Ignitor must reach operating temperature within the OEM-specified warm-up window (commonly under 30 seconds); excessive time often precedes complete failure. |
| Orifice Condition | Orifice must be the correct size for gas type and free of debris or deformation; mismatches lead to weak flame, soot, or unsafe combustion. |
Replacement Considerations, Installation Procedure, and Post‑Install Safety/Performance Checks
The 316536610 Frigidaire Ignitor/Orifice Assembly combines the ignition element and the gas metering orifice into a single replaceable unit that controls initial spark/ignition timing and the localized gas flow for a specific burner.In practice this assembly affects flame establishment, burn pattern, and the ability of safety interlocks to detect a successful light; mismatches in orifice size or ignition type will produce slow ignition, yellow tipping, or repeated shutdowns by flame-sensing circuits. Compatibility depends on manifold pressure, gas type (natural vs.LP), and the appliance model’s burner geometry, so technicians must confirm that the assembly’s orifice and connector style match the range model and service specifications before installation.
When replacing the assembly, isolate electrical power and the gas supply, then remove only the fasteners and seals required to access the burner feed and ignitor connector; clean the mating surfaces to ensure a gas-tight seat and correct burner alignment, and install the new unit with the same orientation and connector retention as the original. After mechanical and electrical connections are restored, perform a sequence of functional checks-verify no gas leaks, confirm reliable ignition across low-to-high settings, observe stable flame shape and sensor response, and monitor for any delayed ignition or repeated lockouts. If a multimeter or manometer is used, compare measurements to the appliance service manual rather than relying on generic values.
- Install: shut off power and gas; remove old assembly; inspect and replace gaskets or seals; seat new assembly and secure fasteners to hand-tight plus specified turn if documented.
- Electrical: reconnect ignitor harness and confirm continuity per service manual; ensure connectors are fully engaged and routed away from heat paths.
- Leak test: apply a soapy solution or electronic leak detector to fittings and orifice area at normal supply pressure.
- Operational check: cycle through low, medium, and high settings; observe ignition timing, flame stability, color, and sensor feedback; verify no fault codes persist.

Q&A
What is the 316536610 Frigidaire Ignitor/Orifice assembly?
The 316536610 is an ignitor and orifice assembly used on certain Frigidaire gas ranges and ovens. The ignitor is a hot-surface device that heats and glows to open the gas valve,and the orifice is the small jet that meters gas flow into the burner.The assembly replaces a failed ignitor and its matched orifice to restore reliable ignition and correct gas flow.
How do I know the ignitor/orifice assembly is bad?
Common symptoms include the oven burner failing to light, long ignition delay, the ignitor glowing dimly or taking a long time to reach bright orange, or the oven cycling on/off without sustaining a flame. A bad orifice could cause weak or uneven flame.Note: an ignitor can show electrical continuity yet still be too weak to draw the required current to open the gas valve.
Can I safely replace the 316536610 myself?
Yes, a mechanically inclined homeowner can replace it, but observe safety precautions: shut off the gas supply and disconnect electrical power before beginning. Work in a well-ventilated area, avoid damaging gas lines, and follow the appliance’s service manual. If you’re uncomfortable working with gas or electrical components, hire a qualified appliance technician.
How do I test the ignitor to confirm it needs replacement?
Initial checks: visually inspect for cracks or breakage and see if the ignitor glows.Use a multimeter to check for continuity-loss of continuity indicates a failed element. Though, continuity alone isn’t definitive: a functional-looking ignitor can be electrically weak. The most reliable test is measuring the ignitor’s operating current (using a clamp ammeter) while it attempts to ignite-if it draws less than the manufacturer’s specified amperage or doesn’t get bright orange quickly, it should be replaced.
Do I need a different orifice for natural gas versus LP (propane)?
Yes. Orifice size and flow characteristics differ between natural gas and LP. If your appliance was converted to LP, you must use the proper LP orifice and conversion kit. Using the wrong orifice can cause improper flame, unsafe combustion, or poor heating performance. Check the appliance model’s conversion instructions or consult Frigidaire for the correct orifice for your gas type.
What tools and parts do I need for the replacement?
Typical tools: screwdriver set (Phillips and flat), socket set, pliers, adjustable wrench, and possibly a nut driver. You may need replacement mounting screws, a gasket or seal if the original is damaged, and a thread sealant appropriate for gas fittings if the job requires loosening pipe threads (follow the manufacturer’s instructions). Always confirm whether the replacement assembly includes mounting hardware and the correct orifice for your gas type before starting.
After installing the new assembly the oven still doesn’t light – what should I check?
Check that power and gas are turned back on and connections are tight. Verify the ignitor is securely connected and positioned correctly near the burner port. Inspect the safety valve and wiring for damage, and ensure the orifice is the correct size and not clogged. If the ignitor glows but the valve never opens,the gas safety valve or control board might potentially be faulty. If uncertain, contact a qualified technician to perform pressure and electrical tests.
Is the 316536610 an OEM part and where should I purchase it?
316536610 is an OEM Frigidaire part number (or commonly listed for Frigidaire appliances). For best fit and reliability buy from authorized frigidaire parts dealers, the manufacturer’s parts website, or reputable appliance parts suppliers. Aftermarket alternatives exist but verify compatibility, warranty, and that the orifice matches your gas type before purchasing.
